In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
[0022] Please also read Figure 1 to Figure 2 As shown, the utility model provides the following technical solutions: a bored pile core hole 200 imaging detection hole wall cleaning device 100, comprising a water pipe 10, an umbrella-shaped nozzle 30, a water connecting pipe 20 and a brush cylinder 40; the umbrella-shaped nozzle 30 is connected to one end of the water pipe 10; one end of the water connecting pipe 20 is connected to the other end of the water pipe 10, and the other end of the water connecting pipe 20 is connected to a high-pressure water source; the brush cylinder 40 is sleeved on the outer wall of the water pipe 10, the water connecting pipe 20 is configured as a hard rubber hose, and the water pipe 10 is configured as a metal pipe.
[0023] When imaging and testing the core drilling hole 200 of the pile foundation, since the hole wall of the core drilling hole 200 is covered with mud, the camera cannot obtain a clear image, so the hole wall of the core drilling hole 200 must be cleaned first.
[0024] In the bored pile core hole 200 imaging detection hole wall cleaning device 100 provided in the present embodiment, a high-pressure water source is connected to the water connecting pipe 20, and then one end of the water delivery pipe 10 connected to the umbrella-shaped nozzle 30 is inserted into the core hole 200, and the high-pressure water source connected to the water connecting pipe 20 flows through the water delivery pipe 10 to spray an umbrella-shaped high-pressure water flow from the umbrella-shaped nozzle 30, and the umbrella-shaped high-pressure water flow washes the mud skin attached to the hole wall of the core hole 200. Subsequently, the user can slowly move the cleaning device 100 down from the hole mouth of the core hole 200 to the bottom of the core hole 200, and then slowly pull the cleaning device 100 from the bottom of the core hole 200 to the hole mouth of the core hole 200. In this process, the brush tube 40 on the outer wall of the water delivery pipe 10 can contact and clean the hole wall of the core hole 200, that is, complete the cleaning work of the hole wall of the core hole 200. The cleaning device 100 can quickly and efficiently clean the wall of the bored pile core hole 200 by combining spraying and brushing.
[0025] In some embodiments, the water receiving pipe 20 is connected to the water delivery pipe 10 through a first pipe joint 50; the umbrella-shaped nozzle 30 is connected to the water delivery pipe 10 through a second pipe joint 60; and the brush tube 40 is located between the first pipe joint 50 and the second pipe joint 60. The water receiving pipe 20 and the water delivery pipe 10 are connected through the first pipe joint 50, so that the water receiving pipe 20 can be easily disassembled from the water delivery pipe 10. The umbrella-shaped nozzle 30 and the water delivery pipe 10 are connected through the second pipe joint 60, so that the umbrella-shaped nozzle 30 can be easily disassembled from the water delivery pipe 10. The brush tube 40 is located between the first pipe joint 50 and the second pipe joint 60, so that the brush tube 40 is limited between the first pipe joint 50 and the second pipe joint 60, so as to prevent the brush tube 40 from being separated from the water delivery pipe 10 when cleaning the wall of the core drilling hole 200.
[0026] In some embodiments, a first water delivery channel 201 is disposed inside the water receiving pipe 20, and a second water delivery channel 101 is disposed inside the water delivery pipe 10, and the first water delivery channel 201 disposed inside the water receiving pipe 20 is connected to the second water delivery channel 101 disposed inside the water delivery pipe 10. When the water receiving pipe 20 is connected to a high-pressure water source, the water receiving pipe 20 delivers the high-pressure water source to the second water delivery channel 101 inside the water delivery pipe 10 through the first water delivery channel 201 inside the water receiving pipe 20, and then the water delivery pipe 10 delivers the high-pressure water source to the umbrella-shaped nozzle 30 through the second water delivery channel 101 inside the water delivery pipe 10 for spraying.
[0027] In some embodiments, the brush cylinder 40 is detachably connected to the water pipe 10. When the brush cylinder 40 is aged due to long-term use, the brush cylinder 40 can be removed and replaced on the water pipe 10. After the brush cylinder 40 is removed, a brush cylinder 40 of different specifications can be installed to better clean the wall of the core hole 200.
[0028] In some embodiments, the brush barrel 40 includes a sleeve 401 and bristles 402. The sleeve 401 is sleeved on the outer wall of the water pipe 10, and the bristles 402 are connected to the outer wall of the sleeve 401. The sleeve 401 is set to be a material with elasticity such as silicone. The brush barrel 40 is elastically sleeved on the water pipe 10 through the sleeve 401. The brush barrel 40 cleans the hole wall of the core hole 200 through the bristles 402. When the brush barrel 40 needs to be disassembled and replaced on the water pipe 10, since the sleeve 401 is set to be a material with elasticity such as silicone, the sleeve 401 can be manually pulled away from the water pipe 10 by force, and the brush barrel 40 can be disassembled from the water pipe 10.
