In the present utility model, for convenience of description, the description of the relative positional relationship of each component is described according to the layout manner of fig. 1 of the specification, for example: the positional relationship of up, down, left, right, etc. is determined in accordance with the layout direction of fig. 1 of the specification.
The utility model is further described below with reference to examples and figures, in which: as shown in figure 1, the waterproof structure for the bottom of the basement outer wall comprises a waterproof wall 1, a first elastic layer 2, a second elastic layer 3 and a basement outer wall 4, wherein the right side wall surface of the waterproof wall 1 is attached to the outer side wall surface of the basement outer wall 4, an outer waterproof coating 5 is clamped between the right wall surface of the waterproof wall 1 and the outer side wall surface of the basement outer wall 4, the first elastic layer 2 is paved on the left wall surface of the waterproof wall 1, and the second elastic layer 3 is paved on the bottom ground of the left wall surface of the waterproof wall 1.
The backfill layer 9 is filled in the outer sides of the first elastic layer 2 and the second elastic layer 3, the main effect of the first elastic layer 2 and the second elastic layer 3 is to help disperse the pressure of soil, prevent the backfill layer 9 from excessively extruding the basement outer wall 4 and avoid gaps of the backfill layer 9 caused by larger sedimentation, and further induce leakage risk of the basement.
The first elastic layer 2 and the second elastic layer 3 are made of the same material and can be polystyrene foam plates, the polystyrene foam plates are light materials and have good compression resistance and waterproof performance, and meanwhile, the polystyrene foam plates are good heat insulation materials and have the main effects of uniformly dispersing the force of the backfill soil layer 9 to a large area, so that the pressure born by the basement outer wall 4 is reduced, the probability of larger sedimentation of the backfill soil layer 9 is greatly reduced, the generation of cracks of the backfill soil layer 9 is effectively avoided, the probability of surface water leaking into a basement through the cracks is greatly reduced, and the polystyrene foam plates have good ageing resistance and can play a role stably for a long time.
The waterproof wall 1 is in a reinforced concrete structure, the waterproof wall 1 is generally nailed on the basement outer wall 4, the bearing and tensile capacity of the basement outer wall 4 can be enhanced, the backfill layer 9 is convenient to subside, the waterproof coating on the basement outer wall 4 cannot be pulled apart, and the outer surface of the waterproof wall 1 is further coated with a first waterproof coating to prevent groundwater infiltration. The first waterproof coating can generally effectively improve the waterproof performance of the basement and prevent the basement from being damaged due to long-term erosion by water. The first waterproof coating may be a polyurethane waterproof coating, an asphalt waterproof coating, or the like.
The basic steps for preparing the reinforced concrete waterproof wall 1 are as follows:
1. preparing materials: cement, sand, crushed stone, steel bars and waterproof agents;
2. building templates according to design requirements, wherein the size and shape of the templates are matched with those of the waterproof wall 1 to be built;
3. reinforcing steel bars are paved in the templates and fixed in place, so that sufficient strength and stability are ensured;
4. according to the requirement of the concrete proportion, adding cement, sand, broken stone and a proper amount of waterproof agent into a concrete mixer for mixing and stirring;
5. pouring the mixed concrete into the formwork to form a layer of thick concrete around the reinforcing steel bars;
6. leveling the surface of the concrete, and adopting a trowel or a scraper to carry out finish treatment so as to ensure that the surface of the concrete is flat and smooth;
7. when the concrete is not completely dried, a layer of first waterproof paint can be brushed to ensure that the waterproof effect is better;
8. when the concrete is completely dried, the template can be removed, and the reinforced concrete waterproof wall 1 is prepared.
It should be noted that the thickness of the reinforced concrete waterproof wall 1 is generally between 15cm and 25cm, and the specific size should be adjusted according to the specific design requirements, and in addition, the amount of the waterproof agent should be noted when the concrete is stirred, so as to ensure that the concrete has sufficient waterproof performance.
According to actual needs, the waterproof structure for the bottom of the basement outer wall is further optimized or/and improved: further, as shown in fig. 1, a water-stopping mortar layer 7 is further disposed on the inside corner of the joint between the waterproof wall 1 and the basement outer wall 4, and the water-stopping mortar layer 7 is located between the upper end surface of the waterproof wall 1 and the outer wall surface of the basement outer wall 4.
The water-stopping mortar layer 7 is a known technology, and by arranging the water-stopping mortar layer 7, the water-stopping mortar layer can further avoid that surface water erodes the junction between the waterproof wall 1 and the basement outer wall 4 along the ground seam, thereby causing the waterproof failure between the waterproof wall 1 and the basement outer wall 4 and finally affecting the waterproof performance of the basement outer wall 4.
Further, as shown in fig. 1, a water guiding gentle slope 8 with a lower left and a higher right is arranged on the ground below the second elastic layer 3.
The water guiding gentle slope 8 can drain the water in the backfill layer 9 to one side far away from the basement outer wall 4, so that the long-term erosion of the waterproof wall 1 and the basement outer wall 4 by the groundwater can be further avoided, and the risk of leakage of the basement in the later stage is greatly reduced.
Further, as shown in fig. 1, an inner waterproof coating 6 is further coated on the inner wall surface of the basement outer wall 4.
Before the waterproof wall 1 is installed, the inner and outer wall surfaces of the basement outer wall 4 are required to be cleaned, and then a layer of second waterproof coating, namely an inner waterproof coating 6 and an outer waterproof coating 5, is coated, wherein the second waterproof coating can be polyurethane waterproof coating, asphalt waterproof coating and the like, and the basement outer wall 4 can have better waterproof capability by arranging the outer waterproof coating 5 and the inner waterproof coating 6, so that the basement water leakage condition is further avoided. The structure of the basement exterior wall 4 should be maintained as uniform as possible to prevent the difference in permeability of the waterproof paint. Meanwhile, the surface is tidy and smooth, and burrs or adherends cannot be formed, so that the waterproof effect is ensured.
