DETAILED DESCRIPTION

[0020] In order to make those skilled in the art better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0021] As Figure 1 shown, a kind of underground continuous wall waterproof construction structure, including basement concrete side wall 1, the side of this side wall stably set blocking side wall 2, forms the first line of defense to groundwater penetration.

[0022] Meanwhile, the embodiment is located between adjacent four basement concrete side walls 1, and bearing column 3 is set with accurate spacing. The top of these bearing columns 3, prefabricated concrete bridge block 4 is fixed firmly, and the end of these bridge blocks is ingeniously embedded in the recess specially provided in the side wall of basement concrete side wall 1, to ensure the stability and waterproof performance of the structure.

[0023] On the upper surface of the prefabricated concrete bridge block 4, a layer of cold primer leveling layer 5 is first laid, which not only enhances the flatness of the surface, but also provides a solid foundation for the subsequent coating. Above the cold primer leveling layer 5, there is a fixed epoxy floor paint layer 6, which gives the floor excellent wear resistance, slip resistance and easy cleaning properties.

[0024] In the specific construction process, first, the basement concrete side wall 1 is poured, and after it is completed, the formwork is removed, and then the pouring of the blocking side wall 2 is carried out. It is worth noting that the blocking side wall 2 adopts a trapezoidal structure with an inclined edge, which closely fits the outer wall of the basement concrete side wall 1, effectively enhancing the waterproof effect. After the formwork is removed, a layer of polyurethane non-woven fabric 7 is fixedly laid on the inclined surface of the blocking side wall 2, and then an asphalt sealing layer 8 is fixedly arranged on the outer surface, which further improves the impermeability of the side wall.

[0025] In addition, between the four adjacent basement concrete side walls 1, from bottom to top, there are stone filling layer 9, fine sand filling layer 10 and backfill soil layer 11, forming a multi-level waterproof and drainage system. The height of the stone filling layer 9 is controlled at 30-40 cm, and the height of the fine sand filling layer 10 is between 10-15 cm. After the fine sand filling layer 10 is laid, vibration equipment is used for vibration treatment to ensure that the fine sand can fully fill into the gaps of the stone filling layer 9. The selected stone size is 5-10 cm in diameter, ensuring the stability and permeability of the filling layer. Finally, the backfill soil layer 11 is used for tamping treatment, and the water absorption of the fine sand plays a key role in effectively absorbing and removing excess water in the backfill soil layer.

[0026] The last step is to erect the prefabricated concrete bridge block 4 between the bearing column 3 and the basement concrete side wall 1, and firmly fix it through anchor bolts. Then, use cement mortar for leveling treatment, and then lay the cold primer leveling layer 5 and the epoxy floor paint layer 6 in turn to complete the construction of the entire waterproof construction structure.

[0027] The implementation of the above technical scheme not only increases the blocking side wall 2 to increase the lateral thickness of the basement concrete side wall 1 in contact with the soil, effectively reducing the risk of side penetration; but also through the continuous construction of the prefabricated concrete bridge block 4, the ground level of the entire basement is raised, thereby effectively avoiding the situation of basement ground water seepage, significantly reducing the potential threat of continuous heavy rainfall to the safety of the basement

[0028] The above has only described certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
