Decoration technology sharing: construction technology of indoor decoration water pipe

Waterway water pipe installation is an essential process in family decoration. At present, the installation of water pipes in home decoration is mainly carried out by the decoration master, but many owners and friends also hope that they can understand the construction technology of water pipes, so that they can clearly understand the installation of water pipes at home. Today, Bian Xiao will talk about the construction technology of indoor decoration water pipes:

Construction technology of indoor decoration water pipe;

Construction process: installation preparation-prefabrication-pipeline installation-pipeline pressure test-pipeline anticorrosion and thermal insulation-pipeline flushing.

Construction technology of indoor decoration water pipe: 1, installation preparation

Familiar with the drawings carefully, refer to the civil structure diagram, decoration diagram and related equipment professional drawings, check whether the coordinate elevations of various pipelines intersect and whether the space occupied by pipeline layout is reasonable, discuss and solve problems with designers and related personnel in time, and handle the change negotiation records.

According to the design drawings, check whether the reserved hole size is correct, and draw lines to locate the pipeline coordinates and elevation.

Construction technology of indoor decoration water pipe: 2. Prefabrication

According to the drawing requirements and the actual situation, measure the size according to the position of the reserved hole, and draw the processing sketch. Measure the pipe size according to the sketch and disconnect the pipe. The fracture surface should be even, and the flying thorns inside and outside the fracture surface should be removed with a milling cutter or scraper, and the outer edge should be milled into an angle of15. Before bonding, the socket should be inserted for testing, but not all, which is generally 3/4 of the depth of the socket. After the trial insertion is qualified, wipe the moisture and dust of the socket to be bonded with cotton cloth. If there is oil, acetone should be removed. Apply adhesive with a brush, first coat the socket and then the socket, and then insert it vertically with force. When inserting and bonding, gently rotate the socket to facilitate the uniform distribution of the adhesive, and the adhesive can be firmly bonded in about 30 seconds to 1 minute. Wipe the adhesive on the spill immediately after it is secured.

Construction technology of indoor decoration water pipe: 3. Pipeline installation:

(1) According to the design position of the piping system and sanitary equipment, combined with the size of the equipment drain and the structural requirements of the drain pipe nozzle, and in coordination with the construction of civil structures, nozzles or pipe fittings are reserved on the walls, beams and floors;

(2) Check the position and size of each reserved hole and connect them;

(3) Measure according to the direction of the pipeline and the centerline mark of each pipe section, draw the measurement template diagram, and indicate the size in detail;

(4) According to the measured sample diagram, select qualified pipes and fittings for piping and pipe cutting. After the prefabricated pipe section is made, check the size between nodes and the orientation of pipe joint according to the small sample diagram;

(5) According to the specifications, select the forms of the support and the fixed bracket, and determine the specifications and quantity of the support;

(6) After the civil wall is painted, the materials and prefabricated pipe sections can be transported to the installation site, and the pipes and expansion joints are installed in turn according to the reserved nozzle position and the center line of the pipes, and the nozzles are connected;

(7) On the floor where a fire sleeve or fire ring needs to be installed, first put the fire sleeve or fire ring outside the pipe section, and then connect the pipe interface.

(8) Pipeline installation shall be carried out in layers from bottom to top, with riser installed first, horizontal pipe installed later and continuous construction;

(9) After the pipeline system is installed, the appearance quality and installation size of the pipeline should be re-checked. After recheck, conduct water test.

Construction technology of indoor decoration water pipe: 4. Pipeline pressure test.

Buried pipes, vertical pipes in pipe wells, horizontal branch pipes in ceiling and pipes with dew prevention requirements need to be watered before concealment. The irrigation height should not be lower than the upper edge of the bottom sanitary ware or the height of the bottom ground. After filling water 15 minutes, fill it for 5 minutes, the liquid level will not drop, and the pipes and interfaces will be qualified without leakage. In the toilet branch pipe irrigation test, if each floor needs to be closed, there are two ways to place the airbag: one is to install a horizontal drainage branch pipe while doing it, and put the airbag down from the tee; One is the final unified operation. If there is an inspection port on this floor, install the airbag above the inspection port; If there is no inspection port on this floor, connect the airbag to a 5m-long trachea (oxygen belt can be used), and slowly lower the airbag from the inspection port on the upper floor until it is estimated that the airbag is under the tee. Inform relevant personnel before the pressure test, sign and accept after the pressure test is qualified, and go through the process handover procedures. Then drain water, and then proceed to the next hidden process.

Construction technology of indoor decoration water pipe: 5. Anticorrosion and heat preservation of pipelines.

In pipeline anticorrosion, the anticorrosion of water supply pipeline laying and installation should be carried out according to the design requirements and national acceptance specifications, and all damaged parts of galvanized steel brackets and pipelines and exposed buckles should be painted with antirust paint. Pipeline insulation should meet the design and the requirements of the owner. The water supply pipeline laid in the basement and equipment layer should be insulated with 40mm thick glass wool pipe shell, and then wrapped with composite aluminum foil after galvanized iron wire binding.

Construction technology of indoor decoration water pipe: 6. Pipeline flushing

Pipeline pollution will be caused during pipeline installation, so the pipeline should be washed clean after installation. Generally speaking, the water should be pumped directly, and the water should be adjusted to the maximum to allow the water to flush the water pipe.

The above is a detailed introduction to the construction technology of indoor decoration water pipes, hoping to help everyone. For more decoration knowledge, please continue to pay attention to the decoration of Tuba Rabbit, and Bian Xiao will continue to provide you with more contents.
