Description

Technical Field

[0001] This utility model relates to the field of anti-seepage structure technology, and in particular to an auxiliary component for preventing rainwater from entering deep foundation pits. Background Technology

[0002] The main function of dewatering and seepage prevention devices for deep foundation pit support is to prevent groundwater and rainwater from seeping into the foundation pit, maintain a dry environment inside the foundation pit, thereby facilitating construction work and ensuring construction quality and safety. It can increase the stability of the slope and the bottom of the pit, prevent soil particles from being lost due to water, and effectively protect surrounding buildings, roads, and underground pipelines, avoiding damage to the surrounding environment caused by water level changes or soil instability.

[0003] An existing deep foundation pit support dewatering and seepage prevention structure (Announcement No.: CN222252145U) has at least the following drawbacks: The device introduces rainwater into the foundation pit through an arc-shaped guide plate for unified extraction, but debris such as dead branches, fallen leaves, gravel, and soil particles will enter the foundation pit along with the rainwater, causing blockage of the water pipes during pumping, and the gravel and soil particles will settle at the bottom of the foundation pit, which is not conducive to cleaning. Utility Model Content

[0004] This utility model is a deep foundation pit anti-rainfall auxiliary component proposed to overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A deep foundation pit dewatering auxiliary component includes a water collection tank, a drain frame, and a pump. The water collection tank is located between the steel sheet pile supports of the deep foundation pit. Side baffles are respectively installed on the upper parts of the left and right sides of the water collection tank. Several square grooves are formed on the top of both sides of the water collection tank, and the side baffles are respectively inserted into the corresponding square grooves and connected to the water collection tank by bolts. The drain frame is located inside the water collection tank, and its outer side is fitted to the inner wall of the water collection tank. A pipe groove is formed through the bottom of the drain frame. The pump is used to extract and discharge the water accumulated inside the water collection tank. A first water-retaining frame and a second water-retaining frame are respectively provided on both sides of the water collection tank, and the first and second water-retaining frames are connected to the upper part of the corresponding steel sheet pile supports of the deep foundation pit.

[0006] Preferably, the bottom front and rear sides of the side baffle are both attached to the top of the corresponding first and second water baffles. The second water baffle has the same structure as the first water baffle, and the first water baffle includes a docking groove, a sliding groove, and a mounting plate.

[0007] Furthermore, a connecting groove is provided through one side of the first water-retaining frame, and the first water-retaining frame is inserted through the connecting groove into the upper part of the I-beam in the deep foundation pit steel sheet pile support. A sliding groove is provided on the side of the first water-retaining frame near the water collection tank, and the top two sides of the water collection tank are slidably connected to the sliding grooves provided on the corresponding side of the first water-retaining frame and the second water-retaining frame.

[0008] Furthermore, both the first and second water-blocking frames are provided with side baffles at their tops. Each side baffle includes a partition and a top seat, with the top seat fixedly connected to one side of the partition.

[0009] Furthermore, the bottom of the top seat is provided with a slot, which is adapted to the top of the U-shaped steel in the deep foundation pit sheet pile support. The top seat is inserted into the top of the deep foundation pit sheet pile support through the slot. The outer side of the partition is flush with the outer side of the corresponding deep foundation pit sheet pile support. Several ear plates are fixedly connected to the side of the top seat away from the partition. The ear plates are located on the upper part of the corresponding first water-retaining frame or second water-retaining frame.

[0010] Furthermore, the ear plate is fixedly connected to the corresponding first or second water baffle by bolts. A water guide channel is provided on the outer side of the side baffle. The side of the water guide channel is fixedly connected to the side of the corresponding partition. A pipe is fixedly connected through the end of the water guide channel. The pipe and the pipe channel are both located on the same side of the water collection tank.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. During rainy weather, workers install the rainproof components on the sheet pile support of the deep foundation pit. The water pump is placed at the edge of the foundation pit, and the water pipe is inserted into the slot of the sluice frame. The partition and side baffles block the top of the water collection tank, which can block the water flow to a certain extent. When the water flow is large and passes through the partition and side baffles into the water collection tank, the sluice frame at the top of the water collection tank filters the fallen leaves and mud particles in the water, causing the fallen leaves and mud particles to fall into the sluice frame and prevent them from entering the water pipe and causing pipe blockage. The bottom of the water collection tank is inclined, which guides the water flow to the bottom side of the water collection tank. The water pump is started to pump the water inside the water collection tank and discharge the water. Workers lift the sluice frame to remove it from the water collection tank and dump the fallen leaves and sand inside. This method is more time-saving and labor-saving, and improves work efficiency.

[0012] 2. The soil layers near the foundation pit are mostly slope-shaped. To reduce the amount of water flowing directly into the foundation pit along the slope, trenches are dug at the edge of the deep foundation pit sheet pile support and at the lowest point of the slope. A drainage ditch is located in the trench on one side of the side retaining seat, which isolates the slope from the foundation pit. The upper part of the drainage ditch is flush with the ground, which facilitates the direct flow of water into the drainage ditch. The drainage ditch is inclined to guide the flow of water. The connecting pipe at the end of the drainage ditch is connected to a water pipe, so that the water flows from high to low through the drainage ditch to the connecting pipe. The water then enters the water pipe for drainage and discharge. Attached Figure Description

Therefore, after installing this utility model above the deep foundation pit, the side baffle 102 and the cover plate are used to block the water collection tank 1. The first and second water-blocking frames 5 and 6 essentially achieve the blocking and sealing of the deep foundation pit. When the accumulated water is too large and overflows the side baffle 102, the first water-blocking frame 5, or the second water-blocking frame 6, the accumulated water carrying fallen leaves and mud enters the upper part of the water collection tank 1. The sieve frame 2 at the top of the water collection tank 1 filters the water, causing the fallen leaves and mud particles to fall into the sieve frame 2 and separate from the water flow, preventing the fallen leaves and mud from entering the water pump 3's pumping pipe and causing blockage. The water pump 3 is started to pump the water inside the water collection tank 1 and discharge the water from the water collection tank 1. The workers lift the sieve frame 2, and the sieve frame 2 is moved out of the water collection tank 1 to dump the fallen leaves and sand inside. This device can effectively prevent excessive precipitation from entering the foundation pit from the top and also facilitates the workers to clean up the fallen leaves and sand brought by the accumulated water.
