Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a foundation pit drainage device for construction engineering construction. Background Technique

[0002] A foundation pit is an earth pit excavated at the designed position of the foundation according to the base elevation and the foundation plane size. With the rapid development of modern construction industry, high-rise and super high-rise buildings are increasing day by day. Due to the large upper load of high-rise and super high-rise buildings, compensatory foundations are mostly adopted, and multiple basements are generally set to facilitate the stability of the buildings. However, this leads to a large buried depth of the foundation and a deep excavation of the foundation pit. When excavating a deep foundation pit in an area with a high groundwater level, the soil aquifer is cut off, and groundwater will continuously seep into the foundation pit, causing quicksand, slope instability or a decrease in the bearing capacity of the foundation. Therefore, drainage work needs to be carried out on the foundation pit;

[0003] In this regard, it can be known from the retrieval of the novelty search agency that the publication number CN218405508U discloses a foundation pit drainage device for construction engineering construction, including a main body and a drain pipe. The lower end of the drain pipe is provided with a conveniently detachable ring frame. The lower end position inside the ring frame is provided with an outwardly protruding guide ring. A filter plate for filtering impurities and guiding them is arranged inside the ring frame; after filtering impurities such as gravel through the filter plate, its inclined structure and the impact force of water flow can make it slide outward to push the limit ring outward for discharge, and then flow outward after being guided by the guide ring. The operation is simple and can effectively avoid the blockage of impurities.

[0004] The above-mentioned foundation pit drainage device disclosed in the technology uses a water pump to pump the water in the construction foundation pit through the drain pipe for external drainage, and uses the filter plate to filter and intercept the sediment solid impurities in the water during pumping. However, there are still the following deficiencies in use: 1. (Although the bottom of the filter plate has an inclination, and the inclination can be appropriately used to wash the solid impurities to the side for discharge when water enters), some solid impurities will get stuck in the filter holes of the filter plate itself, and there will still be a large blockage and poor drainage phenomenon of the filter plate, and the filter plate cannot be effectively cleaned and dredged during filtration and pumping, and the dredging effect is not ideal; 2. (For larger solid impurities, there will also be a phenomenon of accumulation and covering outside the filter plate and being unable to be discharged from the side gaps), and the larger solid impurities outside the filter plate cannot be stably removed during use; In view of this, this application proposes a foundation pit drainage device for construction engineering construction to solve the above problems.

The backwash dredging component is used to backwash and dredge the cylindrical stainless steel filter screen 6 from the inside out, reducing the phenomenon of poor water inlet caused by solid impurities clogging the mesh holes of the cylindrical stainless steel filter screen 6 itself;

[0028] A driving motor 8 is fixedly installed on the left side of the round box 2 and is located inside the fixed box 7.

The rotating shaft 11 is fixedly installed with the bottom end of the output shaft of the driving motor 8; the arranged rotating shaft 11, gear 9, external gear ring 10 and dial rods 12 cooperate. The driving motor 8 is used to drive the rotating shaft 11 to rotate. The rotating shaft 11 drives the rotating pipe 5 to rotate through the gear 9 and the external gear ring 10 in sequence, realizing further driving the cylindrical stainless steel filter screen 6 to rotate. The rotating shaft 11 also drives a plurality of dial rods 12 to rotate to dial and clean the solid impurities adhering to the outer side of the cylindrical stainless steel filter screen 6 outward, preventing the impurities from statically accumulating on the outer side and causing blockage, and further improving the cleaning and dredging effect.

[0031] The usage method of this embodiment is as follows: When the foundation pit drainage device for building construction is in use, the bottom end of the water pipe 101 is placed in the building construction foundation pit. The drainage pump 1 is used to pump the water in the building construction foundation pit through the water pipe 101 and perform the external drainage work. The cylindrical stainless steel filter screen 6 is used to filter and intercept the sediment solid impurities in the water in the foundation pit, achieving the effect of draining the building engineering foundation pit.

[0032] During drainage, the operator uses an external remote control to operate the small water pump 13 and the driving motor 8 to start. When the driving motor 8 starts, it drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the gear 9 to rotate. The gear 9 drives the external gear ring 10 meshing with it to rotate. The external gear ring 10 drives the rotating pipe 5 to rotate. The rotating pipe 5 drives the cylindrical stainless steel filter screen 6 to rotate. When the rotating shaft 11 rotates, it also drives a plurality of dial rods 12 to rotate. When relatively large solid impurities adhere and accumulate on the outer side of the cylindrical stainless steel filter screen 6, the rotation of the cylindrical stainless steel filter screen 6 in cooperation with the rotation of the dial rods 12 can dial and move the relatively large solid impurities accumulated on its outer side outward, preventing the impurities from statically accumulating on the outer side and causing blockage, and improving the cleaning effect.

[0033] When the small water pump 13 is started, a part of the filtered water inside the cylindrical stainless steel filter 6 is extracted through the L-shaped suction pipe 14 and pumped into the L-shaped pipe 15. The water then passes through multiple backwash pipe heads 16 in a close manner from the inside to the left to dredge the cylindrical stainless steel filter 6. In conjunction with the rotation of the cylindrical stainless steel filter 6, the entire circle of the inner side of the cylindrical stainless steel filter 6 is backwashed, cleaned and dredged during water pumping and filtering.
