[0002] A deep foundation pit refers to an excavation, support and dewatering project with an excavation depth of more than five meters or a depth of less than five meters but with particularly complex geological conditions, surrounding environment and underground pipelines. Due to the complex underground structure, in the process of digging the deep foundation pit, it is easy for the pit wall to leak or seep through the pit wall. In order to ensure the quality of the deep foundation pit, it is usually necessary to use plugging materials to seal the leaking parts to repair the deep foundation pit.

[0003] The prior art discloses a deep foundation pit plugging device with a patent announcement number of CN213651713U. The above patent uses a lifting device to drive a lifting plate to lift and lower, so that the plugging device installed on the lifting plate can plug the leaks on the side walls of the deep foundation pit. The entire plugging operation is simple and convenient, and there is no need to manually climb a ladder to plug the side walls of the deep foundation pit. However, the following deficiencies still exist in actual use: From a practical point of view, the depth of the leakage position of the deep foundation pit is usually uncertain, and the device cannot adjust the length of the pumping pipe and the slurry delivery pipe according to the leakage at different depths, which affects the plugging effect. The pumping pipe and the slurry delivery pipe need to be disassembled and replaced, affecting work efficiency.

[0004] Therefore, a deep foundation pit plugging device is needed to solve the problem in the prior art that the lengths of the water pumping pipe and the slurry delivery pipe cannot be adjusted according to the different depths of the leak. Utility Model Content

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that the output pipe 807 is fixedly connected to the inside of the connection block 806, and one end of the output pipe 807 is connected to the telescopic pipe 808, and the telescopic pipe 808 slides on the vertical plate of the fixing frame 801;

[0028] The telescopic tube 808 can ensure that when the output tube 807 is telescoped, the water pump 6 or the slurry delivery pump 7 can operate normally, thereby improving the practicability of the mechanism.

[0029] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that one end of the two telescopic tubes 808 is connected to the input end of the water pump 6 and the output end of the slurry delivery pump 7 respectively.

[0030] According to the above working process, it can be known that: through the telescopic mechanism 8, the output pipe 807 can be driven to telescopically move, which is convenient for adjusting the length of the output pipe 807 for leaks of different depths, thereby improving the plugging effect of the leak, and there is no need to disassemble and replace the output pipe 807, thereby improving work efficiency.
