Description

Technical Field

[0001] This utility model relates to the field of drainage structure technology, and in particular to a foundation pit drainage structure. Background Technology

[0002] In construction engineering, foundation pit construction is a crucial component of foundation engineering. Especially during deep foundation pit excavation, due to complex geological structures and high groundwater levels, continuous groundwater seepage and rainfall-induced water accumulation within the pit can easily disrupt excavation and support operations. This can lead to slope instability, foundation softening, and even landslides, seriously threatening the lives of construction workers and project progress. Furthermore, prolonged water accumulation can negatively impact concrete pouring quality and the waterproofing performance of underground structures, ultimately reducing the overall durability and stability of the project. To ensure construction safety and project quality, a reasonable and efficient drainage system is typically required to promptly collect and quickly remove accumulated water from the foundation pit, ensuring a dry and stable construction site and improving construction efficiency and safety.

[0003] Currently, traditional foundation pit drainage methods mostly use a single drainage pipe in conjunction with a sump well for pumping operations. However, this type of structure has many shortcomings, such as a single drainage path, low drainage efficiency, and a tendency to cause local water accumulation; the drainage outlet is easily blocked by silt, affecting the drainage effect; and it lacks automatic control functions, requiring frequent manual intervention, which increases management costs and operational risks.

[0004] Therefore, a foundation pit drainage structure needs to be designed to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0023] Example: A foundation pit drainage structure, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the structure includes a foundation pit body 1, drainage pipes 2, water pumps 5, water pumping pipes 6, fixing plates 7, and filter components. Multiple drainage pipes 2 are evenly distributed and connected to the four upper walls of the foundation pit body 1. Inclined grooves 3 are respectively opened on the four sides of the foundation pit body 1, and the four inclined grooves 3 are interconnected. Water collection troughs 4 are respectively opened at two diagonally arranged positions on the left and right sides of the foundation pit body 1, and the inclined grooves 3 and water collection troughs 4 are interconnected. Water inlet grooves are respectively opened on the two sides where the water collection troughs 4 and inclined grooves 3 are interconnected. Water pumps 5 are respectively installed at the bottom of the two water collection troughs 4, and a water pumping pipe 6 is respectively connected to the top of the two water pumps 5. The other ends of the two water pumping pipes 6 extend out of the foundation pit body 1. Fixing plates 7 are respectively welded to the upper inner walls of the two water collection troughs 4, and the fixing plates 7 are located in the middle of the water pumping pipes 6. Filter components are slidably connected inside both water collection troughs 4.

[0024] like Figure 3 , Figure 5 and Figure 6As shown, the filter assembly includes a filter frame 8, a pull rod 9, and a filter screen 10. The upper part of the two water collection tanks 4 is slidably connected to the filter frame 8. The filter frame 8 is made of stainless steel. The filter frame 8 is in sliding contact with the fixing plate 7. Two pull rods 9 are installed on the top of the two filter frames 8 by bolts. The filter screen 10 is installed at the bottom of the two filter frames 8.

[0025] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it also includes a water level detector 11, a detection rod 12, a control module 13, a support plate 14, and an alarm 15. The tops of the two water collection tanks 4 are respectively connected to the support plate 14 by welding. The tops of the two support plates 14 are respectively equipped with water level detectors 11. The bottoms of the two water level detectors 11 are respectively equipped with detection rods 12. The bottom ends of the two detection rods 12 pass through the support plate 14 and extend to the bottom of the water collection tank 4. The tops of the two support plates 14 are respectively equipped with the control module 13 by bolts. The control module 13 is electrically connected to the water level detectors 11, the detection rods 12, and the water pump 5. The left and right sides of the upper part of the pit body 1 are respectively equipped with alarms 15 by bolts at diagonally arranged positions. The alarms 15 are electrically connected to the control module 13.

[0026] When this device is needed, its operation procedure is as follows: During the construction of the foundation pit, multiple drainage pipes 2 are evenly arranged and installed on the four upper walls inside the foundation pit body 1 according to the design drawings to ensure that seepage water from all directions can be discharged in time. When seepage or rainwater accumulation occurs in the foundation pit, the water flows into the inclined trough 3 through the drainage pipes 2. The four interconnected inclined troughs 3 effectively collect the water flow and guide it into the collection tank 4 through the inlet trough. As the water flow continues to enter, the water level in the collection tank 4 gradually rises. At this time, the water level detector 11 senses the water level change through the detection rod 12. When the water level reaches the set start value, the control module 13 automatically starts the water pump 5 to discharge the water accumulated in the collection tank 4 to the outside of the foundation pit through the pumping pipe 6. During this process, the water flow needs to pass through the filter frame 8, where impurities such as mud, sand, and gravel are intercepted by the filter screen 10, thereby effectively preventing the water pump 5 from being affected by impurities and affecting normal operation. The control module 13 continuously monitors the water level change in the collection tank 4 and automatically controls the start and stop of the water pump 5 according to the water level, realizing the drainage operation. In the intelligent management of the industry, if the water level rises rapidly due to heavy rain or other emergencies and exceeds the safety threshold, the control module 13 will determine it as an abnormal state and trigger the alarm 15 to issue an audible and visual alarm, reminding on-site personnel to handle it in time. Personnel can manually start the backup pump or perform manual drainage intervention to ensure the safety of the foundation pit. After each use, the device should be inspected and maintained, including: checking whether the drainage pipe 2 is unobstructed and removing blockages; cleaning the sediment in the inclined chute 3 and the inlet chute to keep the water flow smooth; pulling the lever 9 to remove the filter frame 8 and cleaning the filter screen 10 to prevent clogging caused by long-term use. The filter frame 8 is made of stainless steel, which has good corrosion resistance and mechanical strength and is suitable for long-term use in humid environments. In the absence of water, the control system will automatically stop the water pump 5 and put the equipment into standby mode to prepare for the next use. When used again, simply repeat the above operation process. It is easy to operate and maintain, and is suitable for the actual application needs of various foundation pit projects.
