Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction, in particular to a side wall anti-drainage structure. Background Art
[0002] Modern buildings often have deep underground foundations, with the side walls often designed as extra-long concrete structures. These walls are compacted with backfill soil around them. To facilitate construction and reduce costs, this backfill contains large amounts of construction waste, resulting in extremely low water absorption and drainage rates. In extreme weather conditions, such as sudden increases in rainfall, surface water will rapidly seep into the ground through the backfill, causing a sudden increase in pressure on the side walls. This can lead to cracking, dampness, and water seepage, compromising the safety of the building structure.
[0003] The existing methods to solve the above problems are generally to use plugging materials for sealing, or to install a moisture-proof wall on the inside of the side wall, or to install a waterproof layer (waterproof coating or waterproof membrane) on the side wall. Among them, the plugging measures are often not thorough, leakage is prone to recurrence, and it costs a lot of manpower and material resources. The moisture-proof wall approach takes up a large indoor space, has low construction efficiency, and unstable construction quality. The waterproof layer has no drainage measures and is soaked for a long time, which greatly shortens the service life of the waterproof layer. In addition, for some old buildings without basements, their underground foundations are relatively weak, and the walls of the above-ground buildings are more prone to moisture and water seepage, resulting in damage to the walls and posing a threat to personal safety. The above-mentioned waterproof measures need to be implemented on the inside of the underground foundation, which is difficult to apply to such buildings. Even if they are barely applied to above-ground buildings, their waterproofing effect will be greatly reduced.
[0004] In summary, the existing side wall drainage structure has the problems of high cost and poor effect. Utility Model Content
[0005] The utility model discloses a side wall anti-drainage structure with a simple structure, aiming to improve the problems of high cost and poor effect of the existing side wall anti-drainage structure.
[0006] The utility model adopts the following scheme:
[0007] A side wall waterproof and drainage structure, comprising a collecting pipe, a drainage component, and a geotextile wrapped around the outer periphery of the collecting pipe and the drainage component.

The drainage component is fixed on the outer wall of the side wall and is located within the backfill soil layer, and includes drainage plates distributed crosswise and longitudinally. Each drainage plate is provided with a water passage, a first water inlet, and a second water inlet communicated with the water passage. Among them, the water passage is arranged through along the extending direction of the drainage plate. The first water inlet is arranged on the side surface of the drainage plate and is opened along the extending direction of the water passage.

The ends of the longitudinally distributed drainage plates are connected to the collecting pipe through a connecting piece, thereby forming a grid-shaped drainage layer.
[0008] As a further improvement, each of the drainage plates is formed by stacking a plurality of plate bodies with an S-shaped cross section. Each plate body is provided with a water passage, a first water inlet, and a second water inlet.
[0009] As a further improvement, the cross section of the drainage plate is rectangular, and at least three layers of the plate bodies are stacked in the width direction.

[0013] As a further improvement, the collecting pipe is a bundled pipe, and the outer sheath diameter of the bundled pipe is 100 mm.
[0014] As a further improvement, each drainage plate is fixed to the side wall through a stool-shaped fastener, and the stool-shaped fastener is locked to the side wall through a nail.

[0018] 1. The drainage component of the present application is fixed to the side wall, including a first drainage board distributed horizontally and a second drainage board distributed vertically. A plurality of first drainage boards and the second drainage boards are arranged crosswise to form a drainage layer. When surface water seeps into the ground along the backfill soil layer, the water flow can enter the water passage from the first water inlet on the side of the drainage board. The two second water inlets are connected through joints between the drainage boards, so that the water flow can enter each drainage board along the water passage and flow into the second drainage board at the bottom of the side wall to enter the water collecting pipe, and then flow from the water outlet end of the water collecting pipe to the municipal pipe network or the water collecting well, thereby realizing the drainage of the accumulated water in the backfill soil layer, reducing the pressure of groundwater on the side wall, and avoiding problems such as cracking, dampness return, and water seepage of the side wall.

[0036] Embodiment
[0037] Combined with Figures 1 to 5, this embodiment provides a side wall waterproof and drainage structure, which is applicable to the side walls 3 of underground areas such as basements, parking lots, underground passages, and stations, and is also applicable to old buildings without basements. A trench with a depth of 1 - 1.5 m can be dug around the building, and then a concrete wall is poured through a formwork and a steel bar structure, and the side wall waterproof and drainage structure is arranged on the side of the concrete wall. Specifically, the side wall waterproof and drainage structure includes a water collecting pipe 1, a drainage component 2, and a geotextile wrapped around the outer periphery of the water collecting pipe 1 and the drainage component 2. The water collecting pipe 1 is arranged along the bottom of the side wall 3, and its water outlet end is connected to the municipal pipe network or a sump well; the drainage component 2 is fixed on the outer wall of the side wall 3 and is located in the backfill soil layer 4, and includes a plurality of drainage plates distributed crosswise in the horizontal and vertical directions. Each drainage plate is provided with a water passage 231, a first water inlet 232, and a second water inlet 233 communicated with the water passage 231. Among them, the water passage 231 is arranged through along the extending direction of the drainage plate, the first water inlet 232 is arranged on the side of the drainage plate and is opened along the extending direction of the water passage 231, the second water inlet 233 is arranged at the end face of the drainage plate, and the second water inlets 233 on two drainage plates are communicated through a joint 5. The ends of the drainage plates distributed longitudinally are connected to the water collecting pipe 1 through a connecting piece 6, thereby forming a grid-shaped drainage layer.
[0038] Exemplarily, the side wall 3 is a concrete shear wall. The drainage plates distributed horizontally are the first drainage plates 21, and the drainage plates distributed longitudinally are the second drainage plates 22. A plurality of first drainage plates 21 and second drainage plates are arranged crosswise to form a drainage layer. When surface water seeps into the ground along the backfill soil layer 4, the water flow can enter the water passage 231 from the first water inlet 232 located on the side of the drainage plate. The two second water inlets 233 are communicated through the joint 5 between the drainage plates, so that the water flow can flow into each drainage plate along the water passage 231 and converge into the second drainage plate 22 located at the bottom of the side wall 3 to enter the water collecting pipe 1, and then flow from the water outlet end of the water collecting pipe 1 to the municipal pipe network or the sump well, thereby realizing the discharge of the accumulated water in the backfill soil layer 4, reducing the pressure of groundwater on the side wall 3, and avoiding problems such as cracking, dampness return, and water seepage of the side wall 3.
[0039] It should be noted that in this embodiment, a grid-shaped drainage layer with vertical and horizontal intersections is arranged on the wall surface of the side wall 3 to achieve the discharge and dredging of groundwater and avoid the influence of water flow pressure on the side wall 3. Its structure is simple, only requiring the installation of pipes with low cost, and the mesh drainage layer has good drainage effect, which can form a favorable protection for the side wall 3. Even on a building foundation without a basement, side walls 3 can be arranged around its bottom, and by setting a waterproof and drainage structure on the side walls 3, the problems of water seepage and damp return of the above-ground building walls can be prevented, improving the safety of the building. There is no need to construct inside the underground wall, and it is also convenient to be applied to existing buildings without damaging the internal structure of the existing buildings. In addition, by arranging geotextiles wrapped around the outer periphery of the drainage component 2 and the water collecting pipe 1, external soil particles, etc. can be filtered to avoid blockage of the drainage component 2 and the water collecting pipe 1.
[0040] In a preferred embodiment, the water collecting pipe 1 is a bundled pipe. The outer sheath diameter of the bundled pipe is 100 mm, and a plurality of micro pipes are arranged inside the outer sheath. The arrangement density of the micro pipes inside the outer sheath is high, which can reduce the noise generated by water flow impact. At the same time, the cost of the bundled pipe is low, which can further reduce the overall cost of the side wall waterproof and drainage structure.
[0041] Based on the above embodiments, in an alternative embodiment of the present utility model, referring to Figure 5 , each drainage board is formed by stacking a plurality of plate bodies 23 with an S-shaped cross-section. Each plate body 23 is provided with a water passage 231, a first water inlet 232, and a second water inlet 233. The plate body 23 can be formed by extrusion, with light weight, thus improving the construction efficiency. The two openings of the S shape form the second water inlet 233, enabling water flows from various angles to enter the drainage board. The arrangement of the S-shaped plate body 23 can also enhance the side compressive resistance, with strong overall bearing capacity. Preferably, the cross-section of the drainage board is rectangular, and at least three layers of plate bodies 23 are stacked in the width direction, and its length direction fits with the side wall 3, thereby increasing the drainage area of the drainage board on the side wall 3. The stacking of three layers of plate bodies 23 can further enhance the side bearing capacity of the drainage board.
[0042] In a preferred embodiment, each drainage board is fixed to the side wall 3 through a stool-shaped fastener 7, and the stool-shaped fastener 7 is locked to the side wall 3 via a nail. Preferably, the joint 5 is cross-shaped for connecting two first drainage boards 21 and two second drainage boards 22. The connecting member 6 is a T-shaped square-to-round joint 5, and the outer peripheries of both the connecting member 6 and the joint 5 are wrapped with geotextiles. Further, the distance between two adjacent first drainage boards 21 is not greater than 2 m, and the distance between two adjacent second drainage boards 22 is not greater than 10 m to ensure the drainage effect and prevent the problem of low drainage efficiency caused by too large a distance. In other embodiments, in combination with Figure 3 and Figure 4 , two or three layers of drainage boards can be arranged horizontally to improve the drainage efficiency.
[0043] On the basis of the above embodiments, in an alternative embodiment of the present utility model, a gravel layer 11 is laid between the outer wall of the water collecting pipe 1 and the geotextile. The gravel layer 11 and the geotextile are tightly wrapped around the outer periphery of the water collecting pipe 1, thereby forming a water blocking layer on the peripheral side of the water collecting pipe 1 to prevent external water flow from entering. Preferably, a pressure sensor is installed in the water collecting pipe 1 for monitoring the groundwater pressure. Among them, the pressure sensor is electrically connected to a control component, and the control component can be a circuit board, a computer or other terminals. By detecting the water pressure in the water collecting pipe 1 through the pressure sensor, the state of the groundwater can be intelligently monitored to facilitate taking emergency measures. The circuit principle and circuit structure between the control component and the pressure sensor are prior arts and will not be elaborated here.
[0044] The implementation of this embodiment includes the following construction steps:
[0045] 1. First, stack the S-shaped plates 23 by gluing or welding to form a drainage board; then, according to the size of the side wall 3, select the appropriate number of drainage boards.
[0046] 2. Lay out the water collecting pipe 1 and insert a connecting piece 6 on the water collecting pipe 1.
[0047] 3. Arrange the drainage boards in a transverse and vertical cross pattern. The cross parts are connected by cross-shaped joints 5, and the vertical drainage boards at the bottom are inserted into the connecting piece 6 to form a grid-like drainage layer; at the same time, fix each drainage board on the side wall 3 through horse stool-shaped fasteners 7. Preferably, four horse stool-shaped fasteners 7 are arranged at a distance of 10 cm around the joint 5, and the distance between the remaining horse stool-shaped fasteners 7 at non-joint 5 positions is 2 m to ensure the connection strength of the drainage assembly.
[0048] 4. Lay a gravel layer 11 on the peripheral side of the water collecting pipe 1.
[0049] 7. Lay geotextiles with a standard of 300 g / m 2 on the outer periphery of both the drainage assembly 2 and the gravel layer 11.
[0050] 8. Lay the backfill soil layer 4.
[0051] The above is only the preferred implementation manner of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model.
