What are the specific provisions of emergency preventive measures for safety production in furniture industry?

Common preventive measures for safe production

Safety production runs through the whole process of construction production from commencement to completion, so safety

Work exists in every sub-project and every working procedure, that is, safety protection is there.

If measures are not implemented, there may be casualties there. Safety supervision should not only supervise and inspect.

To implement the safety protection measures of various parts, we should also understand the main safety technologies in building construction.

Effective measures can be taken during operation to prevent all kinds of casualties and ensure safe production.

I. Earthwork

1. Construction preparation

(1) Investigate the site and remove the ground and ground obstacles. Find out the engineering site situation, open

Geological and hydrological conditions of excavation layer, transportation road, adjacent buildings and underground buried objects.

Objects, ancient tombs, old civil air defense tunnels, cables, water pipes, gas pipes,

Ground obstacles, water and electricity supply, etc. In order to take targeted security measures.

Clear the ground and underground obstacles in the construction area.

(2) Do a good job in flood control and drainage at the construction site, make overall planning and level the site.

Elevation, ensure the smooth drainage of the construction site without water, and set the necessary around the site.

Interception ditch, drainage ditch.

(3) Protect the survey benchmark piles to ensure that the elevation position and size of earthwork excavation are accurate.

Wrong.

(4) Prepare facilities such as electricity, water and roads for construction.

(5) For deep foundation pits that need retaining piles, retaining piles should be made first.

2. Matters needing attention in earthwork excavation

(1) Choose mechanical and manual excavation according to the depth of earthwork excavation and the size of engineering quantity.

Soil or mechanical excavation scheme.

(2) If the excavated foundation pit (groove) is deeper than the foundation of adjacent buildings, a certain elevation shall be maintained during excavation.

Distance and slope, so as not to affect the stability of adjacent buildings during construction, if not.

Can meet the requirements, slope support and reinforcement measures should be taken. And sink during construction.

Drop and displacement observation.

(3) The spoil shall be shipped out in time. If temporary soil piling is needed, backfill and slope of soil piling shall be reserved.

The distance from the toe of the slope to the pit edge should be determined according to the excavation depth, slope and soil type.

Additional lateral pressure of pile and soil should be considered in slope support design.

(4) In order to prevent the soil at the bottom of the foundation pit from being disturbed, the exposure time should be reduced as much as possible after the foundation pit is dug.

Carry out the construction of the next procedure in time. If the next process cannot be carried out immediately.

Reserve 15 ~ 30cm thick overburden soil layer, and dig again during foundation construction.

basis

Attention should be paid to prevent the foundation pit from being soaked, resulting in collapse and landslide accidents.

Healthy. Therefore, drainage measures should be taken when making earthwork construction plan.

3. Safety measures

(1) There should be a single earthwork construction plan in the construction organization design to carry out the construction accurately.

The preparation work, excavation method, slope laying, drainage and slope support should be designed according to the requirements of relevant specifications, and the slope support should have a design calculation.

(2) When digging a foundation pit manually, operators should keep a safe distance, generally 2.5m；;

For multiple mechanical excavations, the distance between excavators should be greater than 10m, and the excavation should be carried out from top to bottom, layer by layer. It is forbidden to dig the toe of the slope first.

(3) Before excavation, carefully check the surrounding environment, not on dangerous rocks or buildings.

Working under an object.

(4) The excavation of foundation pit should be carried out in strict accordance with the requirements, and attention should be paid to the stability of slope at any time during the operation.

Set up the situation and reinforce it in time when problems are found.

(5) Mechanical excavation, multi-step simultaneous excavation of earthwork, should check the stability of the slope.

Determine the safe distance between the excavator and the slope according to the regulations and checking calculation.

(6) Protective railings should be set around the deep foundation pit, and personnel should have special ladders up and down.

(7) The slope and turning radius of the earth-moving road shall comply with the relevant safety regulations.

(8) Blasting earthwork shall comply with the relevant provisions on the safety of blasting operation.

Second, scaffolding

(1) Types of scaffolding

With the increasing scale of infrastructure, there are more and more kinds of scaffolding. Start with an erection

In terms of materials, there are both traditional bamboo scaffolding and metal steel pipe scaffolding. golden

It belongs to steel pipe scaffold, which is divided into fastener type, bowl type and portal type, and there are many varieties. From an upright vertical pole

According to the number of rows, it can be divided into single bent, double bent and full bent. Judging from the purpose of erection, it is also

Divided into masonry frame and decorative frame. However, no matter from the erection of materials, erection of poles to unloading,

Or according to its use, generally speaking, scaffolding is divided into the following three categories.

1. External scaffolding

(1) Single-row scaffold, which is made up of many single-row vertical poles that fall to the ground and are bound by large and small cross bars.

Or fastened together, and erected on the periphery of the building or structure. The main components are uprights, main rails, small rails, poles or supports. , and connected to the wall in accordance with the provisions.

Rachel.

(2) Double-row scaffolding, consisting of multiple rows of vertical rods and large and small cross bars.

Tie or buckle the tie rod and erect it on the periphery of the building or structure. primary

There are vertical rods, main rails, small rails, scissors, diagonal braces and throwing support bases.

Composition. If connected with fasteners, there are three types of fasteners: rotary, cross and straight.

Should be in accordance with the provisions and Rachel wall.

2. Internal scaffolding

(1) Horse-stool-type internal scaffold, in which several horse-stools are evenly placed along the inside of the wall.

Scaffolding shall be laid on the top surface, and diagonal bracing or scissors shall be added at an appropriate distance between stools. The horse stool itself can be made of wood, bamboo, steel or section steel.

(2) Scaffolding in column, consisting of steel columns and cross bars, laid with feet.

Scaffolding, according to the appropriate distance added a certain brace or scissors, and build.

Located on the inner surface of the outer wall.
