Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1 to 4, a waterproof structure for a basement comprises a basement outer wall 1, a polymer composite waterproof roll layer 2, a first protective layer 3, a second protective layer 4 and a concrete retaining wall 5, wherein the polymer composite waterproof roll layer 2 is pasted on the outer vertical surface of the basement outer wall 1, the first protective layer 3 is pasted on the outer vertical surface of the polymer composite waterproof roll layer 2, the second protective layer 4 is installed on one side, facing the basement outer wall 1, of the concrete retaining wall 5, the second protective layer 4 is close to the first protective layer 3, one side, away from the basement outer wall 1, of the concrete retaining wall 5 is a slope 9, so that the backfill outside the concrete retaining wall applies downward pressure to the concrete retaining wall and the pressure towards the basement outer wall direction, and the concrete retaining wall is prevented from toppling towards the backfill direction.
The first protective layer 3 is formed by splicing a plurality of extruded polystyrene foam boards 10; the second protective layer 4 is formed by splicing a plurality of extruded polystyrene foam boards 10, and the transparent adhesive tape is pasted at the splicing joint of the second protective layer 4 facing one side of the concrete retaining wall 5, so that slurry generated when the concrete retaining wall 5 is poured is prevented from flowing between the first protective layer 3 and the second protective layer 4 from the splicing joint.
The opposite face of first protective layer 3 and second protective layer 4 is brushed with one deck paraffin film respectively, utilizes paraffin film to reduce the frictional force between first protective layer and the second protective layer, scrapes each other when avoiding subsiding between first protective layer and the first protective layer and causes first protective layer and second protective layer to drop, and then avoids causing the separation of polymer composite waterproof coiled material layer and basement outer wall.
The concrete retaining wall 5 is internally provided with a vertical reinforcing mesh 6, one surface of the second protective layer 4 close to the concrete retaining wall 5 is provided with a steel plate 7, the center of the steel plate 7 is welded with a connecting rib 8 perpendicular to the steel plate 7, the connecting rib 8 is bound on the reinforcing mesh 6 by a thin iron wire, on one hand, the second protective layer is supported by the reinforcing mesh before pouring, and on the other hand, the second protective layer is used as a template when the concrete retaining wall is poured.
If the height of the concrete retaining wall is less than 4m, the thickness of the top end of the concrete retaining wall 5 is 8cm, and the included angle between the slope surface 9 and the horizontal plane is 89 degrees; if the height of the concrete retaining wall is between 4 and 6m, the thickness of the top end of the concrete retaining wall 5 is 6cm, and the included angle between the slope surface 9 and the horizontal plane is 88 degrees; if the height of the concrete retaining wall is larger than 6m, the thickness of the top end of the concrete retaining wall 5 is 5cm, and the included angle between the slope surface 9 and the horizontal plane is 89 degrees. The construction cost of the concrete retaining wall is reduced on the premise of ensuring the stability of the concrete retaining wall.
