Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering construction, and specifically relates to a civil engineering foundation pit drainage structure. Background Technique

[0002] In civil engineering construction, foundation pit excavation is one of the important construction links. However, during the foundation pit excavation process, water sources such as groundwater and rainwater often pour into the foundation pit. If effective drainage cannot be carried out in time, it will seriously affect the construction progress, increase the construction cost, and even threaten the construction safety. Traditional foundation pit drainage methods often have problems such as low drainage efficiency and easy damage to the drainage structure, and it is difficult to meet the requirements of modern civil engineering construction.

[0003] The utility model with the publication number of CN220521380U provides a civil engineering foundation pit drainage structure, including a foundation pit and a collection mechanism. A water pump is fixedly installed on the surface of the foundation pit. One end of the water pump is fixedly connected with a connecting ring. A fixing mechanism is arranged at one end of the water suction pipe. A groove is opened inside the foundation pit, and a collection mechanism is arranged on the surface of the groove. A filtering mechanism is arranged at the other end of the water pump. In this civil engineering foundation pit drainage structure, through the setting of the collection mechanism, the collection box is placed in the groove, and the water suction pipe is fixed by the fixing block and the fixing ring. Then, the fixing block is connected to the fixing ring through the fixing block groove, the first threaded hole and the first screw, and then the first screw is tightened to fix the fixing block and the fixing ring together, so that the water suction pipe is fixed on the fixing block and will not fall off during use. After the water pump finishes working, the sediment on the surface of the filter plate will fall into the collection box due to gravity, thus facilitating the cleaning of the sediment in the collection box.

[0004] However, the above patent still has the following problems: When draining the civil engineering foundation pit, some sediment will flow into the interior of the device due to the water flow, and some sediment adheres to the inner wall of the device, which is likely to cause blockage of the inlet and outlet of the device, affecting the drainage efficiency of the device. Sediment blockage will not only affect the drainage speed, but may also cause equipment failures, increase the maintenance cost and time, and even lead to paralysis of the entire drainage system, seriously affecting the construction progress and safety. When the device is placed on the edge or inside of the foundation pit, due to factors such as water flow impact, vibration during foundation pit excavation, and uneven distribution of the equipment's own weight, the device may shift or tip over, and the fixing structure of the device needs to be improved.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0042] Embodiment 3: On the basis of Embodiment 1 and Embodiment 2, specifically as Figure 1 and Figure 4 shown, a water inlet 12 is formed on the outer wall of one side of the water accumulation tank 10, and the bottom of the second limiting plate 32 is in close contact with the side wall of the foundation pit edge.

[0043] In summary, through the structures of the water inlet 12, the filter water trough plates 13, the filter water trough 14 and the fixing plate 15, the purpose of filtering, screening and discharging the accumulated water is achieved, improving the flexibility of the device during use, reducing the influence of sediment on the water pump, prolonging the service life of the device, and improving the durability of the device.

[0044] Working principle: The accumulation water tank 10 is placed inside the civil engineering foundation pit, and its top is open, facilitating the natural inflow of the accumulated water in the foundation pit. An inlet 12 is provided on one outer wall of the accumulation water tank 10 to further ensure the smooth introduction of the accumulated water in the foundation pit into the tank. The accumulation water tank is firmly installed in the foundation pit through the fixed ring plate 11 and the limiting structure on one side thereof (including the first limiting plate 31, the third limiting plate 35, the guide rod 36, the second limiting plate 32, the ground-inserting rod 34 in the clamping rod groove 33, etc.), and at the same time, it is ensured that the first connecting plate 30 is closely matched with the limiting structure to increase the stability of the structure. After the accumulated water enters the accumulation water tank, it is preliminarily filtered through two groups of filter water tank plates 13. The filter water tank 14 inside the filter water tank plate 13 is designed to intercept and precipitate larger particulate matters to keep the water quality relatively clear. A filter screen cover 20 is installed at the bottom of the water pumping head 22 of the water pump 27 to further filter fine impurities and prevent the impurities from entering the water pump and the subsequent drainage pipeline. When the water pump 27 is started, the filtered accumulated water is pumped out from the accumulation water tank 10 through the second water delivery pipe 25 and the third water delivery pipe 26, and finally discharged outside the foundation pit through the drainage pipe 29. The threaded sleeve 21 at the top of the filter screen cover 20 is spirally connected with the threaded groove 23 inside the water pumping head 22 to ensure the close fit of the two and improve the water pumping efficiency. To maintain the filtering effect of the filter water tank 14, the cleaning part is connected to the first water delivery pipe 19 between the two water tanks 16 through another input end (the water outlet pipe 28) of the water pump 27 to deliver water to the high-pressure nozzle 18. The high-pressure nozzle 18 rinses the filter water tank 14 to remove impurities such as sediment adhering to the tank wall. This cleaning process can be combined with the drainage process to form an automated cycle, which is started regularly or as needed to keep the drainage structure unobstructed.

Those skilled in the art know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. In addition, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model.
