The foundation pit drainage structure of this embodiment is applicable to the narrow and small place foundation pit drainage in place. Because in-process to the foundation ditch construction, precipitation weather can make place ponding, so the foundation ditch drainage has important effect that can not neglect to whole foundation ditch engineering safety. For solving the drainage problem, most constructors need set up the escape canal at the top of foundation ditch, but when the place was comparatively narrow, the top of foundation ditch did not have unnecessary space and sets up the escape canal. In view of the above situation, as an embodiment of the drainage structure of the foundation pit, as shown in fig. 1 and fig. 2, in this embodiment, the drainage structure of the foundation pit includes a foundation pit 102, a drainage strip 107 and a pipe 105, the foundation pit 102 includes a bottom plate 101 and a side wall 103, a drainage groove 104 is disposed between the bottom plate 101 and the bottom of the side wall 103, the drainage groove 104 is used for storing accumulated water, the drainage strip 107 includes a first end 109 and a second end 110, the first end 109 is connected with a drainage pump 106 and then disposed in the drainage groove 104 for pumping the accumulated water in the drainage groove 104, the second end 110 of the drainage strip 107 is located at the top of the side wall 103 and is used for draining water outwards, the pipe 105 is located at the top of the foundation pit 102 and includes a water inlet and a water outlet 201, the water inlet is connected with. When there is accumulated water in the drainage channel 104, the accumulated water is firstly pumped into the drainage belt 107 by the drainage pump 106, and then the accumulated water can enter the pipeline 105 through the drainage belt 107 and be pumped out of the pipeline 105 by the drainage pump through the cooperation of the drainage device and the drainage pump 106, so that the accumulated water is drained. Known through the above-mentioned structure, during the ponding that is arranged in water drainage tank 104 can be absorbed pipeline 105 through water drainage belt 107, the ponding that is arranged in pipeline 105 can be taken out by the device that draws water, the work of accomplishing the ponding of discharging, compare in the scheme that needs set up the escape canal at the top of foundation ditch 102, in this embodiment, only need set up pipeline 105 at the top of foundation ditch 102, when the place is narrow can't set up the escape canal at foundation ditch 102 top, the foundation ditch drainage structures that this embodiment provided also can guarantee the smooth completion of the work of discharging ponding.

Specifically, referring to fig. 1, the foundation pit 102 includes a bottom plate 101 and a side wall 103, the side wall 103 is disposed obliquely, a drainage groove 104 (which may surround only a part of the bottom plate 101) is formed around the bottom plate 101 between the side wall 103 and the bottom plate 101, and the drainage groove 104 may have any shape, such as a square shape or a circular shape, as long as the drainage groove 104 can be disposed around the bottom plate 101. Also, in the above embodiment, the shape of the pipe 105 is not limited, and may be a square pipe 105, or may be a circular pipe 105, as long as the drainage requirement of the pipe 105 can be satisfied.

As another example, the foundation pit drainage structure further includes a water conduit 108, and the water conduit 108 includes a third end 111 and a fourth end 112, as shown in fig. 1, the third end 111 penetrates through the sidewall 103 of the foundation pit 102 and extends into the soil, and the fourth end 112 extends to the outside of the sidewall 103, and the water conduit 108 is gradually inclined downward from the third end 111 to the direction in which the fourth end 112 extends. During rainfall, contain more moisture in the soil for the soil is easy to landing in to foundation ditch 102, outwards drainage through leading water pipe 108 to the moisture in the soil, make the moisture that is arranged in the soil discharge the moisture in the soil through the leading water pipe 108 that the slope set up, and make moisture flow into water drainage tank 104 in, rethread drainage zone 107 and pumping device are got rid of it outside foundation ditch 102, reach the purpose that reduces the possibility of soil to foundation ditch 102 landing.

As an example, the drainage structure of the foundation pit further comprises a water collection well, the water collection well is distributed in the drainage channel 104, the drainage channel 104 slopes towards the water collection well, and the first end 109 of the drainage strip 107, to which the drainage pump 106 is connected, is located in the water collection well. Since the drain tank 104 is sloped toward the sump, the accumulated water in the drain tank 104 flows into the sump and then is discharged out of the pipe 105 through the pipe 105 by the operation of the drain pump 106 so that the accumulated water can enter the drain zone 107.

Specifically, the distance between two adjacent water collecting wells is 20 meters to 30 meters, and the arrangement ensures that the excessive water collecting wells do not need to be additionally arranged on the premise of meeting the drainage requirement of the foundation pit 102, so that manpower and material resources are wasted.

As an embodiment, the drainage structure of the foundation pit includes a plurality of drainage strips 107, a plurality of three-way nodes 202 are disposed on the pipe 105, one branch of the three-way nodes 202 is connected to the water inlet of the pipe 105, and the other branches can be connected to the second end 110 of the drainage strip 107. The three-way junction 202 eliminates the need for additional openings in the pipe 105 for connection to the drain strip 107.

Referring to fig. 2, as another embodiment, the drainage structure of the foundation pit further includes a grit chamber, and the pipe 105 is in communication with the grit chamber. When the accumulated water enters the pipeline 105, a part of water flowing into the pipeline 105 is pumped out of the pipeline 105 through a water pumping device, and the silt remained in the pipeline 105 flows into the grit chamber.

As another example, as shown in fig. 2, the pipe 105 is inclined from the end far from the grit chamber to the end near the grit chamber (for example, a 1.5% slope is provided for the pipe 105), which can accelerate the flow of the silt in the pipe 105 into the grit chamber while ensuring that part of the water is pumped out by the water pumping device.

As another embodiment, as shown in fig. 1, the drainage structure of the foundation pit further includes a guardrail 113, and the guardrail 113 is located at the other side of the pipeline 105 relative to the foundation pit 102 to protect the pipeline, so as to ensure the safety of personnel.

As another example, the material of the pipe 105 is PVC.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art. Furthermore, the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
