(2) Special rectification of collapse accidents

The compilation of the special construction scheme for collapse prevention should be scientific, targeted and operable, and be approved and signed by relevant personnel, and strictly implemented at the construction site according to the specific requirements of the special scheme; And should formulate special emergency rescue plan.

Before foundation pit (groove), slope, foundation pile, formwork and temporary construction, the construction scheme shall be prepared according to the requirements of the design unit and the geological conditions, construction technology, working conditions and surrounding environment. Deep foundation pit and ultra-high formwork engineering still need to organize scheme demonstration and review as required.

The construction unit shall plan the temporary drainage system in the construction area, and the temporary drainage shall not damage the foundation of adjacent buildings (structures) and dig and fill the slopes. When excavating in areas with complex terrain and geological conditions where landslides and collapses may occur, the design unit shall determine the drainage scheme. When there is surface water confluence, drainage or underground water pipe leakage around the site, the construction unit should organize drainage and take protective measures for the foundation pit. When excavating foundation pits (troughs), slopes and foundation piles below the groundwater level, the construction unit shall reasonably choose dewatering measures to reduce the groundwater level.

When pit (trough) and slope are provided with pit (trough) wall support, the support should be designed according to excavation depth, soil conditions, groundwater level, construction method and adjacent buildings (structures). When removing the support, it should be removed layer by layer according to the backfilling sequence of foundation pit (groove), and it should be removed and filled at the same time to prevent the slope from collapsing or damaging adjacent buildings, and reinforcement measures should be taken when necessary.

All kinds of building materials should be piled up at the edge of foundation pit (groove), slope and foundation pile hole, and piled up at a specified distance. During mechanical excavation of earthwork, operators are not allowed to enter the scope of mechanical operation to clean up or find slopes. After the excavation of foundation pit (trough), the underground structure and installation works should be carried out in time, and the excavation or backfilling of foundation pit (trough) should be carried out continuously. The construction plan should fully consider the inducing factors such as rainy season construction, and put forward the pre-plan measures.

During formwork operation, steel supporting materials and bamboo and wood materials with serious corrosion, deformation, fracture, desoldering and bolt looseness shall not be used as columns. The supporting column foundation should be firm, and the settlement of formwork support system should be strictly controlled according to the design calculation. Braces and columns should be firmly connected to form a whole.

During the construction of foundation pit (groove), slope, foundation pile and formwork operation, special personnel shall be assigned for command and supervision. In case of displacement, cracking and leakage, the construction should be stopped immediately, and the operators should be evacuated from the job site, and the operation can only be started after the danger is eliminated.

When building materials, templates, construction machinery and other materials are stacked on the floor and roof, the construction unit should strictly control the quantity and weight to prevent overloading. When the number of piles is large, the load should be calculated and the floor and roof should be strengthened.

Temporary buildings should be built safely and reliably, and temporary buildings built along the street, open space and at the foot of the mountain should take measures such as wind prevention, flood control, rainstorm prevention and debris flow prevention. The assembled trailer used in the construction site shall have the product certificate.

Eight. Implementation steps

The special rectification work of anti-falling and anti-collapse in construction sites is divided into four stages.

The first stage: the investigation stage (XX to XX). All construction and supervision units carry out self-examination and self-correction, investigate potential safety hazards, eliminate them in time, and formulate corresponding rectification measures and plans for existing problems; The supervision team is responsible for the special inspection of the supervision projects, registering and filing the projects with problems one by one, and tracking and implementing the rectification. ,
