The method not only solves the problem of righting and restoring safety after falling and toppling due to the fact that the waterproof protection plate is adhered to the basement and is easy to be affected by external force, but also reduces labor and materials, and solves the problem that backfill filler possibly damages a waterproof layer, so that the whole waterproof effect of the basement is guaranteed.
Description
Technical Field
The invention relates to the field of waterproof layer construction of an outer wall, in particular to a construction process for preventing a protective plate of a waterproof layer of an outer wall of a basement from being stuck and toppled.
Background
With the development of building construction technology, the technology of the space required underground becomes more mature, and underground buildings become larger. The realization of underground building functions requires that the structure body has good waterproof and anti-permeability performances. The structure can ensure good waterproof and anti-permeability performance of the underground building under the combined action of the waterproof layer and the waterproof layer.
When the underground structure uses the external water-proof structure of the building, the backfilling of the fertilizer groove earthwork can be completed in time by proper protection measures and a reasonable construction method, and the water-proof layer can be well protected from being damaged.
In the environment of energy conservation and emission reduction, the waterproof protective layer is usually made of a polystyrene board with certain elasticity and heat insulation performance. Before earth backfilling of the fertilizer groove, a worker at the project part fixes the polystyrene board on the waterproof layer by adopting a point bonding method, but whatever materials are used for point bonding, but the time after point bonding is prolonged, and the polystyrene board and the waterproof layer can be loosened and toppled; meanwhile, when the earthwork slides down along the pit slope, the loosening and the toppling of the polystyrene board are accelerated by wind power generated in the process of sliding down the soil material. If the polystyrene board is not supported in time and is attached again, the backfilled soil and the waterproof layer are easy to be impacted to cause damage to the waterproof layer. And unnecessary injury can be caused to personnel holding the polystyrene board on the working surface in the process of the soil material sliding downwards. The problem that the safety of workers for supporting the polystyrene board on the working surface cannot be avoided is guaranteed while the waterproof protection board is in a good state in the backfilling process.
In the application of patent publication No. CN 111005443A, a construction method for punching and pasting a heat insulation board of a waterproof protection layer of an outer wall of a basement is disclosed, wherein the heat insulation board is punched and pasted, the position of the heat insulation board is fixed, construction is carried out, but through the pasting mode, the subsequent construction time is prolonged, accidents such as falling and toppling of a waterproof layer can possibly occur, and the convenient and practical effect cannot be achieved.
