Description

Technical Field

[0001] The utility model relates to the technical field of basement waterproofing, in particular to a basement drainage structure. Background Art

[0002] Basements are very popular for their function of expanding the usable space, which has led to the continuous expansion of the construction area and depth of basements. Therefore, with the rapid advancement of China's urbanization process, in order to improve land utilization rate, ensure the structural safety of high-rise buildings, and enhance the urban air defense and anti-destruction capabilities, a large number of basements (including civil air defense basements) have been built in large, medium and small cities.

[0003] The basement bears all the loads of the building and transfers the loads to the soil layer. Its stability is of great significance to the safety and service life of the building. Traditional basements usually adopt negative-pressure waterproofing. Negative-pressure waterproofing first plugs obvious leakage points, then sprays rigid waterproofing, and is paired with a two-component epoxy interface agent to prevent the intrusion of water vapor. Finally, high-flexibility waterproofing is brushed to isolate the indoor and outdoor moisture. However, once leakage occurs, the repair is not only time-consuming but also costly. Moreover, relying solely on waterproofing often fails to achieve the desired effect, and problems such as basement leakage, water accumulation, and dampness often occur due to the damage of the waterproof layer, making the subsequent treatment difficult and costly.

[0026] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Such as Figure 1As shown in the figure, it is a schematic diagram of the basement drainage structure of the present utility model. This structure includes a side wall 1, a main foundation 2, a secondary foundation 3, a partition board 4, a transition hole 13, a drainage unit, a transition groove 14, a drainage groove 15, a transition inclined plane 16, a rammed plain soil layer 17, a drainage inclined plane 18, a leveling layer 19, a waterproof layer 20, an isolation layer 21, a protective layer 22, a coating layer 23, a main water-stop board 24, a secondary water-stop board 25, an embedded board 26, and a support board 27. The side wall 1 and the main foundation 2 are formed by concrete pouring. There is a gap between the side wall 1 and the main foundation 2 for forming the drainage structure.

[0028] The secondary foundation 3 is formed by concrete pouring and is located on the side of the side wall 1 close to the main foundation 2. The top of the secondary foundation 3 is inclined with a transition inclined plane 16, thereby timely draining the rainwater in the transition groove 14 to the drainage groove 15. The higher side of the transition inclined plane 16 is close to the side wall 1, and the lower side of the transition inclined plane 16 is close to the main foundation 2 to prevent the backflow of accumulated water.

[0029] The partition board 4 is fixed on the side of the secondary foundation 3 close to the main foundation 2. One side of the partition board 4 is the transition groove 14, and the other side of the partition board 4 is the drainage groove 15. The transition hole 13 penetrates through the partition board 4 and connects the transition groove 14 and the drainage groove 15. The rainwater, accumulated water, etc. in the basement enter the transition groove 14 through the drainage unit, then enter the drainage groove 15 through the transition hole 13, and finally are timely discharged from the drainage groove 15.

[0030] As Figure 1 shown, the transition groove 14 is arranged above the secondary foundation 3, and the drainage groove 15 is arranged between the partition board 4 and the main foundation 2. The lowest part of the transition inclined plane 16 is connected to the transition hole 13 to ensure that the rainwater in the transition groove 14 can be timely drained through the transition hole 13, avoiding the occurrence of penetration due to long-term accumulation of rainwater.

[0031] The drainage unit is arranged above the partition board 4 and is used to connect the side wall 1 and the main foundation 2. The drainage unit includes a support plate 5, a rubber layer 6, a secondary foundation 7, a first drainage surface 8, a second drainage surface 9, a first drainage hole 10, a second drainage hole 11, and a through hole 12. The support plate 5 is placed on the top of the partition board 4, which is convenient for disassembly to perform internal maintenance. The support plate 5 is made of stainless steel plate. The secondary foundation 7 is arranged on the top of the support plate 5. The secondary foundation 7 is pre-cast and formed by a casting mold and then placed on the support plate 5, which is convenient for disassembly to perform internal maintenance.

[0032] The first drainage hole 10 vertically penetrates through the secondary foundation 7, and the second drainage hole 11 vertically penetrates through the support plate 5. The diameters of the first drainage hole 10 and the second drainage hole 11 are the same and their axes coincide, ensuring that the rainwater flows more smoothly. A rubber layer 6 is arranged between the support plate 5 and the secondary foundation 7 to improve the sealing performance at the joint of the two, avoiding the occurrence of penetration of rainwater through the gap between the two.

[0033] The first drainage surface 8 and the second drainage surface 9 are inclined and arranged at the top of the secondary foundation 7, and the lowest parts of the first drainage surface 8 and the second drainage surface 9 are connected to the first drainage hole 10. Through the inclined first drainage surface 8 and the second drainage surface 9, the rainwater is guided to ensure that the rainwater can be discharged to the first drainage hole 10 in time.

[0034] As Figure 2 shown, the rammed plain soil layer 17 is filled in the drainage trough 15, and an inclined drainage slope 18 is arranged at the top of the rammed plain soil layer 17 to ensure that the rainwater can be discharged in time. Plain soil is the soil in the natural sedimentary soil layer without being doped with other impurities, with a fine, uniform density and a certain viscosity. The plain soil is filled in the drainage trough 15 and then tamped to form an inclined drainage slope 18 at its top. At the same time, the structure of the tamped plain soil layer is more compact and firm, avoiding the collapse caused by the looseness of the plain soil layer.

[0035] The leveling layer 19 is arranged at the top of the rammed plain soil layer 17. The leveling layer 19 is 1:3 cement mortar with a laying thickness of 20 mm. The leveling layer 19 mainly plays a role in leveling, laying the foundation for the subsequent laying of the waterproof layer 20, avoiding the situation of uneven surface and thus affecting drainage.

[0036] The waterproof layer 20 is laid at the top of the leveling layer 19. Usually, the waterproof coiled material is laid on the leveling layer 19 to form the waterproof layer 20. The waterproof coiled material can be selected as ethylene propylene diene monomer (EPDM) waterproof coiled material.

[0037] The isolation layer 21 is arranged at the top of the waterproof layer 20. The isolation layer 21 uses polyester geotextile as the isolation layer 21 to protect the waterproof layer 20 and avoid foreign objects piercing the waterproof layer 20 below, thus avoiding the occurrence of penetration.

[0038] The protective layer 22 is arranged at the top of the isolation layer 21. The protective layer 22 is a C20 fine aggregate concrete layer, which is used to flatten and compact the waterproof layer 20 and the isolation layer 21 below.

[0039] The coating layer 23 is arranged at the top of the protective layer 22. The waterproof coating is coated on the top of the protective layer 22 to form the coating layer 23 (the waterproof coating can be selected as polyurethane waterproof coating or acrylic waterproof coating).

[0040] In actual use, a "concave" - shaped channel steel structure can also be installed on the top of the coating layer 23, and the drainage is carried out by relying on the stainless - steel channel.

[0041] As Figure 3As shown in the figure, the water-stop main board 24 is embedded in the side wall 1 and the auxiliary foundation 3, and the water-stop main board 24 is poured in when the side wall 1 and the auxiliary foundation 3 are poured. The water-stop auxiliary board 25 is integrally connected to both sides of the water-stop main board 24, and the included angle with the water-stop main board 24 is an obtuse angle, preventing rainwater, accumulated water, etc. from penetrating through the gap between the side wall 1 and the auxiliary foundation 3.

[0042] The embedded board 26 is vertically embedded in the side wall 1 and the main foundation 2, and the water-stop main board 24 is poured in when the side wall 1 and the main foundation 2 are poured. The support board 27 is integrally connected to the inner side of the embedded board 26. The support board 27 and the embedded board 26 are in a "T" shape. The support board 5 is placed on the partition board 4 and is supported on the support boards 27 on both sides, improving the stability of the support board 5 and also facilitating disassembly, so as to perform maintenance on the interior.

[0043] The support board 27 and the embedded board 26 are in a "T" shape. Besides satisfying the support for the support board 5, it can also play a role in water-stop, preventing rainwater from penetrating through the gap of the support board 27.

[0044] The basement drainage structure of the present utility model sets drainage holes near the side wall 1, drains rainwater, accumulated water, etc. in the basement into the transition trough 14 through the drainage holes, and then timely drains the water into the drainage trough 15 through the transition holes 13, avoiding the occurrence of groundwater leakage, water accumulation, and dampness, and reducing the construction difficulty, and being more convenient and labor-saving during subsequent maintenance.

[0045] The above embodiments are only used to illustrate the technical concept and characteristics of the present utility model, and their purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it accordingly, and cannot be used to limit the protection scope of the present utility model. All equivalent changes or modifications made according to the spirit and essence of the present utility model should be covered within the protection scope of the present utility model.
