Before use, it should be sent to the legal testing unit for testing, and steel pipes and fasteners with incomplete documents and unqualified testing should not be used.
Tower cranes, external elevators and tic-tac-toe frames shall be installed and dismantled by qualified units according to regulations.
(2) Special rectification of collapse accidents
The preparation of the special construction scheme for anti-collapse should be scientific, targeted and operable, and be approved and signed by relevant personnel, and strictly implemented in 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, operating 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 slope. 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 setting pit (trough) wall support for foundation pit (trough) and slope, the support design should be based on excavation depth, soil condition, groundwater level, construction method and adjacent buildings (structures). When removing the support, it should be removed layer by layer according to the backfill 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 pre-plan measures.
During formwork operation, steel supporting materials and bamboo and wood materials with serious corrosion, deformation, fracture, desoldering and loose bolts 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. The diagonal brace and the column should be firmly connected to form a whole.
During the construction of foundation pit (groove), slope, foundation pile and formwork operation, there should be special personnel to command and supervise. In case of displacement, cracking, leakage, etc., the construction should be stopped immediately, and the operators should be evacuated from the operation 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 shall 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 reinforced.
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 for preventing falling and collapse on the construction site 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. ,
Special rectification scheme for anti-collapse
The second stage: centralized rectification stage (from XX to XX), all construction and supervision units completely eliminate the existing safety hazards, and the supervision team will check the rectification situation and rectify the nonconformities within a time limit.
Three stages: acceptance stage (from XX to XX). Before XX, the supervision team will accept the rectification measures of the supervised project, and those who fail to pass the acceptance will be ordered to stop work immediately for rectification and be informed criticism; From May to May, the District Construction Bureau organized personnel to supervise the development of rectification work in our district, and reported the supervision on the website of Panyu District Construction Bureau.
Four stages: the summary stage (from XX to XX), the district construction bureau summarizes the experience and achievements of special rectification work.
