The utility model discloses a be applied to the waterproof, dampproofing structure of formula of sinking building can prevent that infiltration or moist condition from appearing in formula of sinking building, and the seepage does not take place for the building surface course of protection formula of sinking building.
Please refer to fig. 1 together, for the embodiment of the present invention provides a waterproof and moisture-proof structure for a sunken building, the sunken building includes a building surface layer 10 and a concrete cushion 20 stacked in sequence from top to bottom, the waterproof and moisture-proof structure includes a waterproof layer 30 and a permeable layer 40, the waterproof layer 30 is used for locating between the building surface layer 10 and the concrete cushion 20 to prevent groundwater from upwards permeating to the building surface layer 10, the permeable layer 40 is located below the waterproof layer 30 and is used for locating above the concrete cushion 20, the permeable layer 40 is used for discharging the groundwater.
In this embodiment, the sinking structure can be a basement or a sinking square without a reinforced concrete structural bottom plate. Specifically, this building surface course 10 is the concrete layer, and this formula of sinking building still includes tamped soil layer 50, and this tamped soil layer 50 is folded and is located under this concrete cushion 20, and this concrete cushion 20 is used for supporting other each layer that is located on this concrete cushion 20. The waterproof layer 30 may be a waterproof coating film, a waterproof mortar, a waterproof roll, or the like.
By adopting the scheme of the embodiment of the utility model, the waterproof layer 30 arranged below the building surface 10 is utilized to separate the underground water which possibly permeates upwards from the concrete cushion 20 from the building surface 10, and the underground water is prevented from continuously permeating upwards to the building surface 10, thereby solving the problem of water seepage of the building surface 10; the permeable layer 40 arranged below the waterproof layer 30 is blocked by the waterproof layer 30 and cannot permeate upwards and underground water accumulated below the waterproof layer 30 is actively discharged, so that the humidity degree below the building surface layer 10 is reduced, and the problem that the building surface layer 10 leaks when being affected with damp is solved.
In this embodiment, in order to collect the groundwater having permeated into the water permeable layer 40 and prevent the groundwater from permeating up to the waterproof layer 30 and the building surface 10 on the waterproof layer 30, the water permeable layer 40 is provided with a leakage pipe 41, and the leakage pipe 41 is used for collecting and discharging the groundwater.
Further, the wall of the leakage pipe 41 is provided with a hollow portion 41a, and the hollow portion 41a is used for guiding the groundwater into the leakage pipe 41. Specifically, the hollow portion 41a may be formed by forming one or more through holes on the pipe wall of the leakage pipe 41, and preferably, the hollow portion 41a may be formed by forming a plurality of through holes on the pipe wall of the leakage pipe 41, so that the processing process is simple, and the cost can be reduced. The area of the hollow part 41a is 1/4-3/4 of the area of the pipe wall, the hollow part 41a is approximately tile-shaped, and the cross section of the hollow part is arc-shaped. Preferably, the area of the hollow portion 41a is 3/4 of the area of the pipe wall, that is, the arc length of the arc-shaped cross section of the hollow portion 41a is 3/4 of the pipe diameter of the pipe wall. After the hollow portion 41a of the leakage pipe 41 guides the groundwater into the leakage pipe 41, the groundwater is discharged along the inner surface of the wall 1/4 of the leakage pipe 41.
By adopting the above mode, the efficiency of the groundwater entering the leakage pipe 41 can be improved, so that the efficiency of the groundwater collected and discharged by the leakage pipe 41 is improved, the humidity degree below the building surface layer 10 is reduced, the building surface layer 10 is protected from being affected with damp, and meanwhile, the area of the hollow part 41a is 3/4 of the area of the pipe wall, so that the strength of the leakage pipe 41 can be guaranteed. If the area of the hollow portion 41a is smaller than 3/4 of the area of the pipe wall, the efficiency of the groundwater entering the leaking pipe 41 from the hollow portion 41a is low; if the area of the hollow portion 41a is greater than 3/4, the strength of the leakage pipe 41 is low and the leakage pipe is easily damaged. It can be understood that, the size design of the hollow portion 41a not only improves the efficiency of the groundwater entering the leakage pipe 41, but also ensures the strength of the leakage pipe 41, prolongs the service life, and avoids the situation of secondary construction caused by fracture and damage, thereby increasing the cost.
Furthermore, in order to improve the efficiency of the leakage pipe 41 for collecting the groundwater, the waterproof and moisture-proof structure further comprises a geotextile 42, the geotextile 42 is wrapped outside the pipe wall of the leakage pipe 41, and the geotextile 42 is used for guiding the groundwater into the leakage pipe 41. Specifically, since the geotextile 42 has good water permeability, the groundwater can be guided into the leaking pipe 41, and the geotextile 42 wrapping the wall of the leaking pipe 41 can seal the hollow portion 41a, so as to prevent the condition that the leaking pipe 41 is blocked due to the fact that the gravels outside the wall of the leaking pipe 41 enter the leaking pipe 41 from the hollow portion 41 a.
In this embodiment, in order to enhance the moisture-proof function of the permeable layer 40, the leaking pipes 41 are preferably arranged in pairs, and two adjacent pairs of leaking pipes 41 are spaced and arranged in parallel. At this time, the groundwater in the interval region between the two adjacent pairs of the leaking pipes 41 can be discharged to the two pairs of the leaking pipes 41, respectively, to improve the drainage efficiency of the leaking pipes 41, thereby achieving the moisture-proof effect of the reinforced permeable layer 40.
Further, as shown in fig. 2, arrows in fig. 2 show the flow direction of the groundwater, in order to realize multi-line drainage and improve drainage efficiency, a pair of the leaking pipes 41 are respectively a first leaking pipe 411 and a second leaking pipe 412 connected to the first leaking pipe 411, and the first leaking pipe 411 and the second leaking pipe 412 are arranged in a straight line, so that the groundwater can be discharged along the first leaking pipe 411 and the second leaking pipe 412 in a dispersed manner after entering the first leaking pipe 411 and the second leaking pipe 412. It is understood that, when the waterproof and moistureproof structure is applied to a sunken structure, the groundwater is discharged in a manner of approximately discharging from the center to the periphery, that is, a central diffusion type drainage. Adopt this drainage mode, can improve the efficiency of this infiltration pipe 41 drainage groundwater, and the regional humidity degree all around of building surface course 10 is less than the humidity degree all around of building surface course 10 to this groundwater is less to the central region's of this building surface course 10 influence, avoids appearing building surface course 10 and wets and by the center to the condition of collapsing fast all around.

Specifically, the arrangement that the second end is lower than the first end mainly means that: after entering the first leakage pipe 411, the groundwater flows along the direction from the first end to the second end of the first leakage pipe 411 and is discharged from the second end, and similarly, after entering the second leakage pipe 412, the groundwater flows along the direction from the third end to the fourth end of the second leakage pipe 412 and is discharged from the fourth end. It can be understood that the first leakage pipe 411 and the second leakage pipe 412 are obliquely disposed, and the groundwater in the first leakage pipe 411 and the second leakage pipe 412 can be accelerated to be discharged to the second end or the fourth end under the action of gravity, so as to increase the speed of the groundwater discharged by the leakage pipe 41, reduce the humidity of the submerged structure, and protect the building surface 10 of the submerged structure from leakage.
More specifically, the first end of the first leakage pipe 411 is connected to the third end of the second leakage pipe 412, and when the first leakage pipe 411 or the second leakage pipe 412 is blocked or damaged and the groundwater cannot be drained in time, the groundwater in the first leakage pipe 411 or the second leakage pipe 412 can flow back to the second leakage pipe 412 or the first leakage pipe 411 and be drained, thereby ensuring normal drainage of the leakage pipe 41.
In this embodiment, the water permeable layer 40 is further provided with a drainage pipe 43, the drainage pipe 43 is perpendicular to the leakage pipe 41, and the drainage pipe 43 is connected to the leakage pipe 41 for draining the groundwater in the leakage pipe 41. Specifically, the pipe diameter of the drain pipe 43 may be equal to or greater than that of the leakage pipe 41, thereby ensuring that the drain pipe 43 sufficiently receives the groundwater of the leakage pipe 41. Preferably, the pipe diameter of the drain pipe 43 is larger than that of the leakage pipe 41. The water discharge pipes 43 are provided in two pairs. The second end of the first leakage pipe 411 is connected to one of the pair of drainage pipes 43, and the fourth end of the second leakage pipe 412 is connected to the other pair of drainage pipes 43, so that the groundwater in the first leakage pipe 411 and the second leakage pipe 412 can be drained to the two pairs of drainage pipes 43 respectively.

Accordingly, the groundwater can be drained to both sides along the first drain pipe 431 and the second drain pipe 432, and the efficiency of draining the groundwater of the water permeable layer 40 is improved. Specifically, since the first drain pipe 431 is communicated with the second drain pipe 432, when the first drain pipe 431 or the second drain pipe 432 is blocked or damaged, the groundwater in the first drain pipe 431 or the second drain pipe 432 may flow back to the second drain pipe 432 or the first drain pipe 431 and be discharged, thereby ensuring the normal drainage of the drain pipe 43.
In this embodiment, the waterproof and moisture-proof structure further includes a sump 50, the drainage pipe 43 is connected to the sump 50, the drainage pipe 43 is obliquely disposed on the permeable layer 40, and one end of the drainage pipe 43 connected to the sump 50 is lower than the other end of the drainage pipe 43. Accordingly, the groundwater in the drain pipe 43 can be discharged to the sump 50 at an accelerated speed by gravity, and the drainage efficiency of the drain pipe 43 can be improved.
It can be known that the leaking pipe 41 and the draining pipe 43 in this embodiment are both disposed obliquely in the permeable layer 40, i.e., the leaking pipe 41 and the draining pipe 43 drain water at a certain slope. If the leakage pipe 41 and/or the drainage pipe 43 are not disposed obliquely, the groundwater in the leakage pipe 41 is not easy to flow into the drainage pipe 43, and the groundwater in the drainage pipe 43 can flow back into the leakage pipe 41, which affects the efficiency of the leakage pipe 41 and the drainage pipe 43 for discharging groundwater, and the drainage effect is not good. The leakage pipe 41 and the drain pipe 43 are obliquely arranged, so that the underground water can be orderly drained along the leakage pipe 41, the drain pipe 43 and the water collecting pit 50, and the drainage efficiency is high.
As an alternative embodiment, the groundwater drained into the sump 50 through the drain pipe 43 may be pumped by a water pump.
As another alternative, the sump 50 may be in communication with a ground drain 60, and groundwater discharged into the sump 50 via the drain pipe 43 may be discharged directly to the ground drain 60.

And through the communication of the first leakage pipe and the second leakage pipe and the communication of the first drain pipe and the second drain pipe, when one of the leakage pipes or one of the drain pipes is blocked or damaged, the underground water can flow back to the other leakage pipe or the other drain pipe, so that the normal drainage of the leakage pipes and the drain pipes is ensured.
