Basic Engineering\x0d\1. Construction Technology\x0d\Site Leveling → Positioning and Setting Out → Foundation Trench Excavation → Support Formwork → Pouring Concrete strip foundation → inspection and acceptance → removal of formwork → backfill soil → moisture-proof layer → acceptance of basic structure. \x0d\① Among them: the earth excavation process is as follows: \x0d\ Positioning measurement - burying the axis guide pile - spreading the excavation line - manual excavation - foundation trench inspection - foundation abnormality treatment - entering the next road process. \x0d\2. Construction points\x0d\1) During the earth excavation process, the amount of soil should be piled near the site for backfilling. \x0d\2) During the excavation process, surveyors shall level the pit at any time and nail elevation control piles on the pit wall to control the excavation depth at any time and prevent over-excavation. \x0d\3) When digging, the distribution of underground pipelines should be ascertained in advance and properly handled. \x0d\4) During earthwork construction, attention should be paid to the safe use of construction machinery and maintenance should be carried out before entering the site. During excavation, no other operations are allowed within the working range of the excavator. When loading soil, the driver should leave the cab. Loading soil is strictly prohibited when there are people in the car. \x0d\②This project is C20 concrete. \x0d\After the foundation axis size and base elevation are accepted and the hidden inspection procedures are completed, the measurement and release personnel will promptly calibrate the elevation control line of the 400mm thick concrete epithelium. Before pouring concrete, check whether the size and shape of the cushion is correct and whether the formwork support is firm. When pouring cushion concrete, send special personnel to check the quality of commercial concrete at any time. The concrete surface is scraped with a scraper, and then smoothed and calendered with a wooden trowel. During the construction process, samples should be taken in time and test pieces should be retained.

\x0d\③Earthwork backfill\x0d\After the completion of the foundation project, and after passing the inspection and acceptance by the quality inspection station, the earthwork backfilling will be carried out.\x0d\1) Process flow\x0d\Base layer cleaning → soil quality inspection → layered soil spreading and raking → Ramming and compacting → Inspecting the density → Trimming and leveling → Acceptance. \x0d\2) Construction method\x0d\ Before filling, garbage and other debris at the bottom of the foundation trench should be cleaned up. Before backfilling the foundation, it must be cleaned to the elevation of the bottom surface of the foundation, and loose garbage, mortar, stones and other debris that have fallen back must be removed. \x0d\ Check whether there are any debris in the backfill soil, whether the particle size meets the regulations, and whether the moisture content is within the controlled range. If the moisture content is high, measures such as plowing, drying and evenly mixing dry soil can be used; if the water content of the backfill soil is low, measures such as pre-sprinkling water and moistening can be used. \x0d\After all filling is completed, surface leveling should be carried out. Areas that exceed the design elevation should be leveled in a timely manner according to the line. Areas below the design elevation should be filled with soil and compacted. \x0d\3) Quality standards\x0d\Main control items: Allowable elevation deviation -30mm, layered compaction coefficient meets design requirements. \x0d\General projects: The backfilled soil materials must comply with the design or construction specifications. The layer thickness and moisture content must comply with the design or construction specifications. The allowable deviation of the surface flatness shall not be greater than 20mm. \x0d\ 2. Fence project\x0d\ Laying out → Formwork → Pour concrete base → Maintenance, removal of formwork → Lay brick columns → Install and fix iron railings \x0d\ (1) Foundation cushion concrete \x0d\ Foundation During concrete construction, the concrete cushion and surface must be cleaned and there is no accumulation of water. No soil should fall into the groove. When the side formwork is supported on the foundation pit wall, attention must be paid to the stability of the reinforcement. The formwork support rods must not be directly supported on the soil wall. On top, the lower opening of the support must be supported on the dense soil layer with a backing plate to prevent formwork from occurring due to weak support when pouring concrete. The foundation beam formwork can be reinforced with diagonal braces and opposite braces. The width of specially made bayonet steel bars or angle steel at the upper part of the beam body should be limited. \x0d\When pouring foundation concrete, no construction joints shall be left. \x0d\ (2) Brick foundation \x0d\ Before the construction of the brick foundation, when backfilling the soil on the side of the foundation beam, avoid scattering the soil on the foundation beam. If so, clean the upper part of the foundation beam and pop up the center line and Spread a layer of cement mortar on the edge line, level the local unevenness of the wall above the foundation beam, and then lay bricks to build the wall. You can also backfill the soil after the brick foundation is laid to keep the original concrete surface clean during the brick foundation laying stage, so as to further ensure the quality of the masonry. \x0d\3. Main structure project\x0d\1. Wall project\x0d\Masonry materials of this project:\x0d\Bricks for wall: Masonry materials:\x0d\Use MU10 cement concrete, M7.5 cement Mortar masonry, with off-white cultural stone on the outside \x0d\ (1) The materials used in the masonry project must be tested before use, and unqualified materials are strictly prohibited. \x0d\ (2) Masonry mortar: The variety and labeling of mortar must meet the design requirements. The yellow sand must not contain debris. Tap water is used. The impurity content of the yellow sand is controlled to be less than 3%. \x0d\ (3) Construction preparation. Bricks or blocks must be soaked with water before laying, but the site must not be overly wet or unevenly wet. \x0d\ (4) Before masonry, the mortar debris on the base surface must be cleaned up and watered to moisten it. At the same time, it should be tested; before masonry, openings, pipes and embedded parts should be reserved according to the design requirements of the drawings. \x0d\ (5) The brickwork construction specifications should be strictly followed. Calculate the skin number of the bricks on the layer, the thickness of the mortar joints and other data based on the floor height, window sill and window top height. Pop up the wall axis at the construction site and set it up. Use the skin number rod to control the thickness of the mortar joints to control the height of the masonry, and use three-quarter bricks or small size blocks to match the whole bricks to build the corners and wall ends to achieve the purpose of staggered joints. \x0d\ (6) When masonry is connected, the surface of the joint must be cleaned, watered and moistened, and mortar should be filled to keep the mortar joints straight. \x0d\ (7) When repairing the wall, the corrosion of the tie bars should be checked. If the corrosion is severe, the rust must be removed with a wire brush and other tools before the construction can be concealed. \x0d\ (8) Make mortar test blocks according to the specifications and test them on schedule. \x0d\ (9) The internal and external scaffolding shall be mobile temporary scaffolding.

\x0d\Construction points:\x0d\Before installing the wrought iron fence, you must ensure that the concrete supports are formed and whether the position of the embedded parts is correct. You should also pay attention to the finished wrought iron during transportation. Do not deform or distort it by force. Place it on the axis during installation. and must be firmly fixed. \x0d\2. Steel bar engineering\x0d\1.2.1 Steel bar processing\x0d\A. Steel bars are processed centrally in the on-site steel bar processing room (see the general construction layout plan). When making, attention should be paid to the correct shape of the steel bars, and there are no flat surfaces. Uneven warping phenomenon; the clearance of the hook at the end of the steel bar is not less than 2.5 times the diameter of the steel bar; there must be no cracks at the bending point of the steel bar. For this reason, steel bars above grade II cannot be bent over and then back; the allowable deviation after the steel bar is processed and formed is: ±10mm, stirrup side length ±5mm. \x0d\B. Each batch of steel entering the site must undergo mechanical performance testing in accordance with regulations. Only after passing the test can it be processed and bound. Sampling must be witnessed when submitting for inspection, otherwise it cannot be used as a test piece for inspection. The incoming and finished formed steel bars must be listed and stacked according to specifications and parts. Steel bars should be stacked on pads to prevent corrosion. \x0d\B. Steel bars are connected by binding. \x0d\C. 8.1.3.2 Preparatory work should be done before binding, that is, use the material list to check whether the finished steel bars are consistent with the material list; prepare the required steel bar pads; Draw steel bar location lines on site. \x0d\B. When tying the raft foundation steel bars, the intersection of the upper and lower layers of steel bars should be tied firmly at every point. When tying, attention should be paid to the fact that the wire buckles at adjacent ligating points should be in a figure-eight shape to prevent the mesh from skewing and deforming. The upper steel bars of the raft foundation are supported by steel horse stools. \x0d\C. The protective layer of steel bars is ensured by using 1:1 cement mortar to make pads. The thickness of the pad should be consistent with the required size of the protective layer. \x0d\3Formwork project\x0d\ Use stereotyped combined steel formwork. The formwork should have sufficient strength and stiffness. After entering the factory, the formwork should be classified and stacked neatly according to specifications and models, and the stacking height should not exceed 1.5m. \x0d\The formwork should be cleaned and leveled before use, and a release agent should be applied. After the formwork is removed, it should be stacked in a designated place in time. \x0d\ If the formwork is installed without rushing to the modulus, a small amount of wood formwork should be used. The surface of the wood formwork should be planed, and the connection between the steel and wood formwork should be firm and smooth to prevent convex and concave phenomena after the concrete construction is completed. \x0d\After the formwork is installed, the casting point must be adjusted to ensure the accuracy of the position, verticality and surface flatness of the formwork. If there is no problem, it must be fixed in time (by pulling the top to ensure). \x0d\Formwork removal time, the side formwork concrete strength can ensure that the components will not deform, and the edges and corners can be intact before they can be removed. The internal formwork for the holes can be reserved only after the concrete strength can ensure that the components and the surface of the holes will not collapse or crack. Dismantling; the dismantling time of the formwork should be strictly regulated and controlled. \x0d\4 Concrete Project\x0d\1.4.1 Concrete Supply\x0d\ A JGZ350 concrete mixer is set up on site for mixing and transported to the pouring site with a motorized dump truck. \x0d\1.4.2 Concrete pouring and vibrating\x0d\The foundation concrete is poured at one time, and no artificial joints are required. During the construction process, pay attention to the pouring speed and thickness. \x0d\When vibrating concrete, the duration of vibration at each vibrating point should be such that floating slurry appears on the surface of the concrete and no bubbles are generated. When using a plug-in vibrator, collisions with steel bars, formwork, etc. should be avoided; the depth of the vibrator inserted into the underlying concrete should be no less than 50mm. When using a surface vibrator, the moving distance should ensure that the flat plate of the vibrator can cover the edge of the vibrated part. \x0d\When pouring construction on rainy days, covering measures must be taken after the concrete is poured to prevent the rain from washing away the mud and affecting the quality of the concrete. \x0d\1.4.3 Concrete maintenance and testing\x0d\ After the concrete is poured, the concrete should be covered and watered within 12 hours; the time for watering and curing of concrete should be determined for Portland cement and ordinary silicic acid. The duration of concrete mixed with salt cement or slag Portland cement shall not be less than 7 days. For concrete mixed with admixtures or with impermeability requirements, the duration shall not be less than 14 days; the frequency of watering shall be enough to keep the concrete in a moist state; The curing water should be the same as the mixing water. \x0d\1.4.4 Transportation and pouring of concrete \x0d\ The foundation pouring concrete is transported to the site with a motorized dump truck. When the mixed concrete is transported to the site, it should be watered in time to avoid construction joints.

\x0d\5 Maintenance\x0d\ Cover with plastic sheet or straw curtain for moist curing, and spray part of the area with curing solution. \x0d\6 Scaffolding Project\x0d\1.6.1 In order to ensure that the construction does not interfere with each other, the external scaffolding is required to meet the construction requirements\x0d\1.6.2 Material requirements\x0d\ The scaffolding uses ?48mm, wall thickness 3.5mm steel pipe, which is severely corroded , Bent, flattened or cracked steel pipes are strictly prohibited from being used; \x0d\ Fasteners must use qualified malleable steel fasteners and obtain a production certificate. When the fastener clamps the steel pipe, the minimum distance between the openings should be no less than 5mm; \x0d\Wooden scaffolding boards should be made of pine or fir, and the thickness should not be less than 50mm. Two hoops of galvanized steel wire with a diameter of 4mm should be used at both ends of the scaffolding board. \x0d\1.6.3 Dismantling of the outer frame\x0d\A. The dismantling sequence should be carried out layer by layer from top to bottom. It is strictly forbidden to work up and down at the same time. \x0d\B. All wall-connecting parts should be dismantled layer by layer along with the scaffolding. It is strictly forbidden to remove them first. The scaffolding should be dismantled after the whole or several layers of wall parts are dismantled;\x0d\C. When the scaffolding is dismantled to the height of the last long steel pipe at the bottom (about 6.5 meters), temporary support reinforcement should be erected at the appropriate location first, and then dismantled. Wall-connecting parts; \x0d\1.6.4 Scaffolding allowable deviation\x0d\ Correct the vertical and horizontal deviations of the poles at any time to avoid excessive deviations. \x0d\A. The vertical deviation and total height deviation of the vertical poles shall not exceed 100mm; \x0d\B.
