Drainage device

Abstract

The invention discloses a drainage device. The drainage device comprises a pressure device; the bottom of the pressure device is provided with a pressure pipe; the top of the pressure pipe extends into the pressure device; the bottom of the pressure pipe is located on a base; the pressure pipe is provided with a water pump; the water pump is detachably connected with the pressure pipe; a connecting pipe is horizontally arranged on the water pump in a penetrating mode; each end of the connecting pipe extends into a water storage device; the connecting pipe is communicated and connected with the two water storage devices; the bottom of each water storage device is fixed on the base; the bottom of each water storage device extends into the base; the inner bottom surface of each water storage device is provided with a speed reduction device, wherein a waterproof casing wraps each speed reduction device; each speed reduction device is electrically connected with the water pump. According to the drainage device, the traditional construction method is broken through, the water surging in the process of initial setting of concrete is eliminated, the effect of the underground water on basement floors is effectively reduced to zero, the waterproof and drainage requirements under different conditions can be met, and accordingly the subsequent construction quality is ensured.

Description

technical field [0001] The invention relates to a drainage facility, in particular to a drainage device. Background technique [0002] With the development of urban construction, the distance between adjacent buildings is getting smaller and smaller. During the construction of the basement of high-rise buildings, the use of deep foundation pits and large-area well points will affect the settlement of adjacent building foundations, which will easily lead to cracks in the outer walls and even fractures of building components. Therefore, drainage ditches can only be set on the top of the foundation pit, open ditches are set around the bottom of the pit, and water collection wells are set at a certain distance. After sedimentation in the sedimentation tank, it is discharged into the municipal rainwater pipe network. However, the drainage performance of the general drainage structure cannot achieve the best effect, and it is prone to blockage, and the speed of the water pump is u...
