Abstract
Description
Technical Field
[0001] The present application relates to the technical field of building drainage, and in particular to a drainage structure for underground garage floors. Background Art
[0002] What owners of public areas and garages are most concerned about are hollowing, cracking and leakage. Among them, garage floor leakage receives the most attention and the most complaints.
[0003] At present, the traditional approach to garage flooring in housing construction projects is waterproof reinforced concrete base plate + slope leveling layer + surface layer. The construction unit simply constructs according to the drawings, and does not make optimization suggestions based on the actual situation of the project during the construction process, which often leads to some common quality problems. For example, the spacing between garage collection pits is too large, and there are no drainage ditches on the sides, which cannot quickly drain the ground water to the collection pits, causing water accumulation in the garage. Especially for areas with high groundwater levels, there is a high probability of leakage at the construction joints of the base plate or the post-casting joints after the project is delivered. Groundwater seeps through the gaps to the garage floor, causing water accumulation on the ground, affecting the passage of passing vehicles and owners. Summary of the invention
[0004] In order to overcome the existing deficiencies, an embodiment of the present application provides a drainage structure for an underground garage floor, which can solve the problems of poor drainage and groundwater leakage in the basement mentioned in the above background technology.

[0006] In a specific embodiment, the bottom layer includes a plain soil layer, and a cushion layer is laid on the plain soil layer.
[0007] In a specific embodiment, a waterproof layer is laid on the cushion layer, and a protective layer is laid on the waterproof layer.
[0008] In a specific embodiment, an anti-seepage layer is laid on the protective layer, and the guide groove is opened on the anti-seepage layer.
[0009] In a specific embodiment, the surface layer includes a steel-concrete layer and a decorative layer.
[0010] In a specific embodiment, the surface of the decorative layer is sloped toward the drainage ditch, and the bottom of the drainage ditch is sloped toward the water collection well.
[0011] In a specific embodiment, the drainage ditch passes through the door of the external functional room and a water pipe is provided under the wall.
[0012] In a specific embodiment, the drainage ditch is arranged along an external wall.
[0013] The advantages of the embodiments of the present application are:
[0014] A drain layer and a diversion trough are set between the bottom layer and the surface layer to divert the leaked groundwater along the drain plate to the drainage ditch. Each drainage ditch is connected to a collection well, and finally collected in the collection well and pumped to the outdoor pipeline network, which improves the drainage efficiency and avoids a series of problems such as traffic difficulties, complaints and repairs caused by groundwater seeping into the surface of the basement.

DETAILED DESCRIPTION
[0020] The technical solution in the embodiment of the present application is to solve the problems mentioned in the above background technology, and the overall idea is as follows:
[0021] See also Figure 1-Figure 4A drainage structure for underground garage floor, including a bottom layer 10 and a surface layer 20, a guide groove 30 is provided on the upper surface of the bottom layer 10, a hydrophobic layer 40 is laid on the bottom layer 10, a surface layer 20 is arranged on the hydrophobic layer 40, a drainage ditch 50 is arranged outside the hydrophobic layer 40, and the drainage ditch 50 is connected to an external water collection well. The hydrophobic layer 40 and the guide groove 30 are arranged between the bottom layer 10 and the surface layer 20, which are used to guide the leaked groundwater along the hydrophobic plate to the drainage ditch 50, each drainage ditch 50 is connected to the water collection well, and finally collected in the water collection well to be pumped to the outdoor pipe network, which improves the drainage efficiency, thereby avoiding a series of problems such as difficulty in passage, complaints, and repairs caused by groundwater seeping into the surface of the basement.
[0022] See also Figure 1-Figure 4 The bottom layer 10 includes a soil layer 11, and a cushion layer 12 is laid on the soil layer 11. Here, the soil is compacted, the compaction coefficient is not less than 0.94, and the cushion layer 12 is 100 thick C15.
[0023] See also Figure 1-Figure 4 A waterproof layer 13 is laid on the cushion layer 12, and a protective layer 14 is laid on the waterproof layer 13. Here, the waterproof layer 13 adopts 4mm thick SBS modified asphalt tire waterproofing membrane, and the protective layer 14 adopts 50mm thick C20 fine stone concrete.
[0024] See also Figure 1-Figure 4 , an impermeable layer 15 is laid on the protective layer 14, and a guide groove 30 is opened on the impermeable layer 15. Here, the impermeable layer 15 is poured by concrete, and a Φ20PVC wire pipe is half-buried during pouring as the guide groove 30, with a spacing of 6*6m, which is removed after curing.
[0025] See also Figure 1-Figure 4 The surface layer 20 includes a steel-concrete layer 21 and a decorative layer 22. Here, the steel-concrete layer 21 is a 70-thick C30 fine stone concrete with a single layer of bidirectional steel bars Φ6@250mm, and the decorative layer 22 is laid on it.
[0026] See also Figure 1-Figure 4 The surface of the decorative layer 22 is sloped toward the drainage ditch 50, and the bottom of the drainage ditch 50 is sloped toward the water collection well. Here, the surface of the decorative layer 22, i.e., the garage floor, is sloped by 0.5% toward the drainage ditch 50. If there are drainage ditches 50 on both sides of the garage wall, the drainage ditch 50 is sloped from the middle of the span to the drainage ditches 50 on both sides. The drainage ditch 50 is sloped at a slope of 1%, and the bottom and sides of the ditch are smoothed with 1:3 cement mortar.
[0027] See also Figure 1-Figure 4 , the drainage ditch 50 passes through the external function room door and is provided with a water pipe 60 to pass through the wall. Here, the water pipe 60 passed under is used for the drainage ditch 50 to be connected, and the ground is kept flat, so that it is convenient to enter and exit the function room.
[0028] See also Figure 1-Figure 4 The drainage ditch 50 is set along the external wall. Here, the drainage ditch 50 is set along the inner corner of the ordinary wall, the width of the drainage ditch 50 is 100mm, the location where the drainage ditch 50 is set has a structural column protruding outward, and the center line of the drainage ditch 50 is 100mm outward from the outermost edge of the column. The location where the drainage ditch 50 is set has no structural column protruding outward, and the center line of the drainage ditch 50 is 150mm outward from the inner corner line of the wall root.
[0029] When the present application is used, the hydrophobic layer 40 adopts a 0.5mm thick hydrophobic plate. The water seeping from the bottom layer 10 quickly enters the peripheral drainage ditch 50 through the hydrophobic layer 40. The setting of the guide groove 30 facilitates the rapid drainage of the seepage water. The seepage water finally flows into the collection well along the drainage ditch 50, thereby realizing the rapid discharge of underground seepage water.
[0030] In summary, a hydrophobic layer 40 and a diversion groove 30 are arranged between the bottom layer 10 and the surface layer 20 to guide the leaked groundwater along the hydrophobic plate to the drainage ditch 50. Each drainage ditch 50 is connected to a collection well, and finally collected in the collection well and pumped to the outdoor pipe network, thereby improving the drainage efficiency, thereby avoiding a series of problems such as difficulty in passage, complaints, and repairs caused by groundwater seeping into the surface of the basement.
[0031] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
