[0002] A deep foundation pit refers to a project with an excavation depth of more than 5 meters (including 5 meters), or a project with a depth of less than 5 meters but with particularly complex geological conditions, surrounding environment and underground pipelines. The characteristics of a deep foundation pit include a large excavation depth, complex geological conditions and surrounding environment, and the need to take special support and precipitation measures to ensure construction safety. Due to construction problems in deep foundation pits, various potholes will appear, and water will accumulate in the potholes due to rainfall or groundwater seepage, which will affect normal construction. Therefore, the accumulated water in the potholes in the deep foundation pit needs to be drained before normal construction can be resumed. Construction is carried out; but nowadays, water pumps are used to pump out the randomly distributed accumulated water in the deep foundation pit. Therefore, after the accumulated water in one part of the deep foundation pit is discharged, the staff is required to move the water pump and then pump out the accumulated water in other parts of the deep foundation pit. Each time the accumulated water in different parts of the deep foundation pit is pumped out, the staff is required to manually carry and transfer the water pump.

The No. 1 hose 51 and the No. 2 hose 81 can be respectively passed around a group of bearing rods 41, so that the No. 1 hose 51 and the No. 2 hose 81 are respectively in contact with the two groups of rotating drums 42, and the No. 1 hose 51 and the No. 2 hose 81 are arranged in a serpentine state on the inner side of the connecting frame 4, so that when the pumping ends of the No. 1 hose 51 and the No. 2 hose 81 move, the parts of the No. 1 hose 51 and the No. 2 hose 81 located in the connecting frame 4 can be slightly straightened or retracted to avoid the No. 1 hose 51 and the No. 2 hose 81 from being entangled or squeezed, so as to better allow water to enter the No. 1 hose 51 or the No. 2 hose 81; when the No. 1 hose 51 and the No. 2 hose 81 are pumped When the end moves, the parts of the No. 1 hose 51 and the No. 2 hose 81 located in the connecting frame 4 also start to move. After the No. 1 hose 51 and the No. 2 hose 81 respectively generate friction with the two groups of rotating drums 42, the rotating drum 42 can be rotated to avoid damage to the No. 1 hose 51 and the No. 2 hose 81 due to long-term friction with the load-bearing rod 41; the No. 1 electric telescopic rod 44 is located between the two groups of rotating drums 42, and the No. 1 electric telescopic rod 44 can adopt a three-section telescopic rod, and the load-bearing rod 41 is hollow to reduce the weight of the connecting frame 4, and the fixed end of the No. 1 electric telescopic rod 44 passes through several load-bearing rods 41 away from the ring 3 and is fixed to several load-bearing rods 41.

The part of the No. 1 hose 51 that passes through the connecting shell 5 is fixed to the connecting shell 5. After the automatic telescopic rod 53 is started, the telescopic end of the automatic telescopic rod 53 can drive the No. 1 connecting tube 52 to move downward through the connecting rod, so that the No. 1 connecting tube 52 can drive the telescopic end of the No. 1 hose 51 to move downward. When the No. 1 connecting tube 52 enters the accumulated water, the water pump 31 can be turned on to pump the accumulated water into the No. 1 hose 51, and then discharged through the drainage end of the water pump 31. The filter holes on the No. 1 connecting tube 52 can filter the impurities in the accumulated water; when there are too many impurities accumulated in the No. 1 connecting tube 52, the automatic telescopic rod 53 can be started to make the No. 1 connecting tube 52 drive the fixed tube 6 to move upward, so that the bottom end of the vertical pipe 7 passes through the fixed tube 6 and the top of the No. 1 connecting tube 52 in sequence. After the jack of the No. 1 connecting tube 52 is inserted into the vertical tube 7, the vertical tube 7 pushes the cleaning brush 62 (the cleaning brush 62 is arranged in a circular shape, and the bristles are in contact with the inner wall of the No. 1 connecting tube 52) downward, and the movable end of the spring telescopic rod 61 extends downward (the spring telescopic rod includes a sleeve, a spring and a rod body, the spring is fixed in the sleeve, and the rod body is slidably connected to the inner wall of the sleeve and fixed to the spring). As the cleaning brush 62 moves downward, the inner wall of the No. 1 connecting tube 52 can be cleaned and impurities can be scraped off. At the same time, the cleaning brush 62 can drive the sealing block 64 to move downward through the short rod 63. After the sealing block 64 moves to the bottom of the No. 1 connecting tube 52, the impurities in the No. 1 connecting tube 52 can be discharged through the perforation at the bottom of the No. 1 connecting tube 52, thereby completing the automatic cleaning of the impurities inside the No. 1 connecting tube 52.

When the vertical pipe 7 moves downward and enters the fixed cylinder 6 and approaches the cleaning brush 62, the bottom end of the thin rod 72 first contacts the top of the cleaning brush 62, and then the thin rod 72 pushes the counterweight block 71 upward, and at the same time, the bottom end of the vertical pipe 7 contacts the top of the cleaning brush 62, and after the cleaning brush 62 is pushed downward, when the vertical pipe 7 enters the No. 1 connecting cylinder 52, the rainwater in the connecting shell 5 can be discharged through the water outlet on the vertical pipe 7, and the interior of the No. 1 connecting cylinder 52 is cleaned with the cleaning brush 62, so that the impurities accumulated in the No. 1 connecting cylinder 52 can be cleaned more effectively; when the short rod 63 moves downward, the cleaning plate 65 also moves downward, and the impurities adhered to the inner wall of the No. 1 connecting cylinder 52 can be scraped off. The top of the sealing block 64 is arranged in an arc shape, and the connecting ring 57 with an inclined inner ring surface can make the impurities slide better from the top of the sealing block 64, and slide from the inside of the No. 1 connecting cylinder 52 to the outside.

[0022] like Figure 1 , Figure 4 and Figure 6 As shown, the drainage end of the No. 2 hose 81 is connected to the No. 2 connecting tube 82 with sieve holes on the surface, the telescopic end of the No. 2 electric telescopic rod 83 is fixed to the No. 2 connecting tube 82 through a control rod, and a cleaning brush 84 is fixed to the bottom of the connecting frame 8 through a fixing rod. The No. 2 connecting tube 82 is located on the inner side of the cleaning brush 84, and a notch is provided on the cleaning brush 84 for the control rod fixed to the telescopic end of the No. 2 electric telescopic rod 83 to enter. After starting the No. 2 electric telescopic rod 83 to move the No. 2 connecting tube 82 downward into the water pit, start the water pump 31 to pump the accumulated water into the No. 2 hose 81, and then discharge it through the drainage end of the water pump 31; the inner diameter of the sieve hole on the No. 2 connecting tube 82 is smaller than the diameter of the filter hole on the No. 1 connecting tube 52. When it is necessary to clean the impurities on the No. 2 connecting tube 82, the No. 2 electric telescopic rod 83 can be started to move the No. 2 connecting tube 82 upward, and the cleaning brush 84 can be used to clean the impurities on the No. 2 connecting tube 82 to prevent the impurities from being blocked in the sieve holes on the No. 2 connecting tube 82.

[0023] like Figure 1 and Figure 4As shown, the connection frame 4, the connection shell 5 and the connection frame 8 are respectively provided with a No. 1 battery 43, a No. 2 battery 54 and a No. 3 battery 85; a partition 55 is fixed in the connection shell 5, and the partition 55 is located between the No. 2 battery 54 and the water inlet hole 56. The No. 1 battery 43, the No. 2 battery 54 and the No. 3 battery 85 can respectively supply power to the No. 1 electric telescopic rod 44, the automatic telescopic rod 53 and the No. 2 electric telescopic rod 83; the partition 55 can separate the No. 2 battery 54 from the water in the connection shell 5.

[0024] like Figure 1 and Figure 3 As shown, the drainage ends of the No. 1 hose 51 and the No. 2 hose 81 are respectively fixed to the two water inlet ends of the tee pipe 35 by bolts, and the tee pipe 35 is fixed to the water pump end of the water pump 31 by a flange. The drainage ends of the No. 1 hose 51 and the No. 2 hose 81 can be passed through the gap between every two adjacent bearing rods 41 in sequence, so that the No. 1 hose 51 and the No. 2 hose 81 are in a serpentine state, and then the drainage ends of the No. 1 hose 51 and the No. 2 hose 81 are respectively fixed to the two water pump ends of the tee pipe 35.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a water bag 33 is fixed on the outer ring surface of the ring 3, a drain pipe 34 is connected to the water bag 33, and a connecting pipe 32 connected to the water bag 33 is connected to the drain end of the water pump 31. The water bag 33 can be placed on the bottom surface, so that when the water pump 31 discharges the accumulated water into the water bag 33 through the drain pipe 34, the water bag 33 can store the accumulated water, and then after the pumping end of the external pump is connected to the connecting pipe 32, the water is discharged through the external pumping pump. Therefore, when the ring 3 rotates, the staff only needs to separate the pumping end of the external pump from the connecting pipe 32, and then connect the pumping end of the external pump to the connecting pipe 32, without repeatedly adjusting the position of the drain end of the water pump 31, which further reduces the labor intensity of the staff and avoids the repeated friction of the drain end of the water pump 31 on the ground.

[0026] When in use, a slider is fixed on the inner wall of the sleeve 21, and a slideway adapted to the slider is opened on the column 2, so that the sleeve 21 can move up and down more smoothly; a counterweight plate away from the connecting frame 4 is fixed to the bottom of the ring 3 to ensure the stability of the ring 3; the bottom plate 1 is placed in the center of the deep foundation pit, and then according to the position of the water pit, the No. 1 motor 23 is started to drive the ring 3 to rotate, the position of the connecting frame 4 is adjusted, and then the No. 1 electric telescopic rod 44 is started to drive the connecting shell 5 to move, so that the pumping end of the No. 1 hose 51 is in the water pumping position. When the first hose 51 is in use, the valve on the three-way pipe 35 connected to the first hose 51 can be opened. Subsequently, according to the position of the water pit, the automatic telescopic rod 53 can be started to adjust the position of the water pumping end of the first hose 51, so that the water pumping end of the first hose 51 is close to or away from the connecting frame 4.

[0027] When the water accumulation pit is located directly below the connecting frame 4, the valve connected to the No. 1 hose 51 on the three-way pipe 35 can be closed, and the valve connected to the No. 2 hose 81 on the three-way pipe 35 can be opened. Then, the No. 2 motor 9 is started to rotate the screw rod 91, and the connecting frame 8 is close to or away from the ring 3, so that the pumping end of the No. 2 hose 81 is located directly above the water accumulation pit, and the No. 2 electric telescopic rod 83 is started to make the pumping end of the No. 2 hose 81 enter the water accumulation pit, and then the accumulated water can be pumped out; subsequently, by rotating the ring 3 and making the pumping ends of the No. 1 hose 51 and the No. 2 hose 81 close to or away from the ring 3, all the water accumulation pits in the deep foundation pit can be covered, so as to accurately locate the water accumulation pits in the deep foundation pit, and then the accumulated water can be discharged to the outside of the deep foundation pit;

[0028] At the same time, according to the location of the water pit, the first hose 51 and the second hose 81 can be used together to pump water from different water pits, thereby further improving the discharge efficiency of the accumulated water.
