Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a cavity drainage structure between an enclosure structure and an inner lining wall. Background Art
[0002] When the two walls of the basement enclosure wall are constructed in one, there is a certain gap between the basement lining wall and the enclosure structure, which easily causes groundwater to infiltrate into the gap and cannot be discharged in time, thereby causing leakage of the basement lining wall. In the existing process, waterproof mortar is usually used to fill the gap to solve the leakage problem of the lining wall, but due to the narrow gap, the filling density of the waterproof mortar cannot be guaranteed, and thus the leakage problem of the lining wall after long-term use cannot be completely solved. Therefore, it is necessary to provide a cavity drainage structure between the enclosure structure and the lining wall, which can solve the problem of easy leakage of the lining wall in the prior art. Summary of the invention

DETAILED DESCRIPTION
[0017] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0018] Please see attached Figure 1 A cavity drainage structure between a retaining structure and an inner lining wall, comprising a floor drain 1, a drainage pipe 2 and a drainage trough 3; the floor drain 1 is arranged in the gap between the retaining structure 4 and the inner lining wall 5, one end of the drainage pipe 2 is arranged in the gap between the retaining structure 4 and the inner lining wall 5 and is connected to the bottom of the floor drain 1, and the other end of the drainage pipe 2 penetrates the inner lining wall 5 and is connected to the drainage trough 3; the drainage trough 3 is arranged on the basement floor 6 and extends to a sump (not shown in the figure), and the drainage trough 3 is located on the inner side of the inner lining wall 5 and is filled with pebbles.
[0019] By setting the floor drain 1 in the gap between the enclosure structure 4 and the lining wall 5, the accumulated water in the gap can be collected in the floor drain 1, and then discharged into the drainage trough 3 through the drainage pipe 2. The water in the drainage trough 3 is discharged to the sump through the gaps between the pebbles.
[0020] Preferably, the drainage ditch 3 is located inside the basement, which can discharge the accumulated water in the gap between the enclosure structure 4 and the lining wall 5 through the drainage pipe 2, and can also discharge the accumulated water on the basement floor 6, effectively ensuring the drainage effect inside and outside the basement, thereby ensuring the use quality of the basement.
[0021] The floor drain 1 can be selected according to the actual use requirements. The corresponding model and specification, the drainage pipe 2 can be a PVC pipe or a metal pipe. The floor drain 1 and the drainage pipe 2 are both commonly used drainage tools in building structure construction, and will not be repeated here.
[0022] The setting height of the floor drain 1 is higher than the setting height of the drainage groove 3. The drainage pipe 2 is an L-shaped curved pipe structure, so that the upper end of the vertical section of the drainage pipe 2 is connected to the bottom of the drainage groove 3, and the horizontal section of the drainage pipe 2 passes through the lining wall 5 and is connected to the drainage groove 3.
[0023] The setting height of the floor drain 1 can be adaptively adjusted according to the actual working conditions to ensure that the water in the gap is collected to the floor drain 1 by utilizing the height difference and then discharged into the drainage trough 3 in a timely and complete manner through the drainage pipe 2, ensuring that there is no water accumulation in the gap between the enclosure structure 4 and the lining wall 5, thereby avoiding leakage of the lining wall 5.
[0024] A filling layer 9 is provided at the bottom of the gap between the enclosure structure 4 and the lining wall 5 , the floor drain 1 is installed on the filling layer 9 , and the portion of the drainage pipe 2 located in the gap is arranged in the filling layer 9 .
[0025] Preferably, the filling layer 9 may be made of fine stone concrete, which is used to install the floor drain 1 to a specified height, while wrapping and supporting the drainage pipe 2 to ensure the installation and use stability of the drainage pipe 2.
[0026] A waterproof cement mortar layer 8 is provided in the gap between the enclosure structure 4 and the inner lining wall 5 . The waterproof cement mortar layer 8 is located on the top of the filling layer 9 and slopes to the floor drain 1 .
[0027] The waterproof cement mortar layer 8 is formed by waterproof cement mortar construction and is used to form a 2% slope structure around the floor drain 1, so that all water in the gap between the enclosure structure 4 and the lining wall 5 can be collected into the floor drain 1 to avoid residue.
[0028] The inner lining wall 5 is embedded with an inspection door 501 which is slightly higher than the floor drain 1 , so that the floor drain 1 can be easily maintained and repaired through the inspection door 501 , and the inner lining wall 5 will not leak due to the setting of the inspection door 501 .
[0029] A slope layer 701 , a hydrophobic plate 702 , a protective layer 703 and a leveling layer 704 are constructed on the surface of the basement floor 6 from bottom to top; the slope layer 701 is sloped in the direction of the drainage trough 3 .
[0030] By setting the slope layer 701 with a slope of 0.5%, the water in the hydrophobic plate 702 can be diverted to the drainage groove 3, thereby ensuring that there is no water accumulation on the basement floor 6. The protective layer 703 and the leveling layer 704 can be constructed by concrete mortar according to the design requirements of the basement floor 6, which will not be repeated here.
[0031] The edge of the basement floor 6 extends outward into the enclosure structure 4 and is sealed and connected to the enclosure structure 4 via a seal 601 . The filling layer 9 is constructed on the basement floor 6 .
[0032] The basement floor 6 is integrally cast, which is beneficial to improving the waterproof and anti-seepage performance of the lining wall 5 and the basement bottom, and also facilitates the installation of the floor drain 1 and the drainage pipe 2. The sealing member 601 can preferably be a sealing material such as a water-stopping rubber strip.
[0033] Please see attached Figure 1 , the working principle of the utility model is:
[0034] When water accumulates in the gap between the enclosure structure 4 and the inner lining wall 5, the water is diverted to the floor drain 1 through the waterproof cement mortar layer 8, and is drained to the drainage trough 3 through the drainage pipe 2 through the floor drain 1, and is drained to the sump through the gaps between the pebbles in the drainage trough 3, thereby draining the accumulated water in the gap between the enclosure structure 4 and the inner lining wall 5, thereby preventing leakage of the inner lining wall 5.
[0035] At the same time, the water on the finished surface of the base plate 6 can be guided into the drainage ditch 3 through the hydrophobic plate 702 and the slope layer 701, and discharged to the sump through the drainage ditch 3, thereby draining the water on the base plate 6 and avoiding water accumulation in the basement structure.
[0036] If the floor drain 1 is damaged or blocked, resulting in drainage difficulties and causing leakage in the lining wall 5 , the floor drain 1 can be repaired through the inspection door 501 .
[0037] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
