Description

Technical Field

[0001] This utility model relates to the field of construction drainage technology, specifically a dewatering well structure for building construction drainage. Background Technology

[0002] Traditional dewatering wells often use brick-built protective sleeves or ordinary concrete pipes. In soft soil strata or deep foundation pit construction, the protective sleeves are prone to cracking and collapse due to the lateral pressure of the surrounding soil, causing a large amount of mud and sand to flow into the well, directly damaging the submersible pump. There is no standardized protective structure at the wellhead, and debris can easily fall into the well during construction, clogging the filter pipe or jamming the pump. In addition, there are no sealing measures, and surface water can easily seep into the well, diluting the groundwater concentration and increasing the pumping load. In extremely cold regions, the submersible pump cable and outlet pipe inside the well are prone to freezing, causing equipment shutdown. In industrial sites, acidic substances or heavy metal ions in the groundwater can quickly corrode the steel pipe protective sleeves and pump impellers, requiring the pump to be replaced every 1-3 months on average, resulting in high operation and maintenance costs.

[0003] Currently, the drainage well structure used for construction drainage in this building still has the problem of incomplete flushing of the filter layer. Utility Model Content

[0004] To solve the above problems, this utility model is implemented through the following technical solution: a dewatering well structure for building construction drainage, including a wellhead protective layer, a well pipe connected to the bottom of the wellhead protective layer, a filter pipe connected to the bottom of the well pipe, a water collection pipe connected to the bottom of the filter pipe, a first water pump fixedly connected to one side of the inner wall of the wellhead protective layer, a water outlet pipe connected to the outlet end of the first water pump, a connecting pipe connected to the inlet end of the first water pump, and the connecting pipe penetrating the wellhead protective layer and extending to the bottom of the water collection pipe; The wellhead protective layer includes a well cover, a rotating shaft is fixedly connected to one side of the bottom of the well cover, a protective sleeve is rotatably connected to the bottom of the rotating shaft, a flushing device is fixedly connected to one side of the protective sleeve, a sliding groove is provided on the top of the inner wall of the protective sleeve, and a collection plate is slidably connected to the inner wall of the sliding groove. The rotating shaft can open and close freely without damaging the well cover and the protective sleeve.

[0005] Preferably, the bottom of the protective sleeve is connected to the well pipe, the first water pump is fixed on the inner wall of the protective sleeve, and one side of the inner wall of the protective sleeve is penetrated by the water outlet pipe.

[0006] Preferably, the flushing device includes a water tank, a first pipe connected to one side of the water tank, an inlet of a second water pump connected to the end of the first pipe away from the water tank, a second pipe connected to the outlet of the second water pump, a rotating device slidably connected through the second pipe, a conical barrel connected to the end of the second pipe away from the second water pump, and a nozzle connected to the bottom of the conical barrel. The conical barrel and the nozzle can perform 360-degree all-round flushing of the filter pipe.

[0007] Preferably, one side of the water tank is fixedly connected to the protective sleeve, and the first pipe passes through the protective sleeve and is fixedly connected to the protective sleeve.

[0008] Preferably, one side of the second water pump is fixedly connected to the inner wall of the protective sleeve, the side of the rotating device is fixedly connected to the inner wall of the protective sleeve, and both the rotating device and the conical barrel are penetrated by a connecting pipe.

[0009] Preferably, the rotating device includes a fixed plate, a second motor is fixedly connected to the top of the fixed plate, a roller is fixedly connected to the drive shaft of the second motor, and a friction pad is sleeved and fixedly connected to the roller.

[0010] Preferably, the side of the fixing plate is fixedly connected to the protective sleeve, the top of the fixing plate is penetrated by the second pipe and the connecting pipe, and the second motor is provided with two sets located on both sides of the second pipe respectively.

[0011] This utility model provides a dewatering well structure for building construction drainage. It has the following beneficial effects: 1. The construction drainage well structure is equipped with a wellhead protection layer. The design of the wellhead protection layer, the design of the well cover and the protective sleeve can provide a first layer of protection for the wellhead, which can prevent debris from falling in accidentally. The collection plate intercepts and reduces the situation where debris falls in due to the well cover being opened for a long time. The setting of the flushing device reduces the clogging of the filter layer. The first water pump draws water out of the water collection pipe and discharges it into the drainage system through the outlet pipe.

[0012] 2. The construction drainage well structure is equipped with a flushing device. The design of the flushing device, through the water tank, can ensure that sufficient water is provided when needed. The fixed connection between the conical barrel and the nozzle allows the water flow to be sprayed at a specific angle and range, thereby improving the flushing effect. The design of the rotating device allows the water pipe to be retracted for easy flushing next time.

[0013] 3. The dewatering well structure for construction drainage is equipped with a rotating device. This rotating device is driven by a second motor to rotate the drum, which in turn drives the friction pad to rotate. The automatic telescopic rod can push the curved panel to press the second pipe onto the friction pad. The fixed plate and the protective sleeve are fixedly connected to ensure the stability of the device. At the same time, the second pipe and the connecting pipe pass through the top of the fixed plate, which facilitates the connection and layout of the pipe. Attached Figure Description
