Description

Technical Field

[0001] The present application relates to the field of bored pile construction equipment, and in particular to a device for removing sediment from bored pile holes. Background Art

[0002] Cast-in-place piles are a type of pile made by drilling holes in place and pouring concrete or reinforced concrete. Cast-in-place piles are widely used in construction because of their advantages such as no vibration, no soil squeezing, low noise, and suitability for use in densely built urban areas.

[0003] During the impact drilling construction, the drill bit repeatedly hits the bedrock, turning the bedrock into stone chips and fine powder particles. The relatively small stone chips and fine powder are suspended in the mud and carried out of the hole by the mud, while the larger particles slowly settle and accumulate at the bottom of the pile hole, making it difficult to remove, affecting the construction progress and the quality of the pile. In order to prevent the residue at the bottom of the pile from being too thick and reducing the bearing capacity of the pile, it is usually necessary to remove the debris remaining at the bottom of the hole before pouring underwater concrete.

[0004] A Chinese patent with publication number CN110777791A discloses a sediment cleaning device for a bored pile hole, comprising a cylinder, a passage, a chamber one and a chamber two are arranged inside the cylinder, the passage runs through the cylinder and the chambers one and two, an air supply pipe is passed through the passage, a gear one and a gear two are arranged in a rotational match with the passage, three gears two are arranged and arranged in a circular array, each gear two is respectively meshed with the gear one, a motor one is fixedly connected to the top of the chamber one, a gear three is fixedly connected to the output shaft of the motor one, the gear three is meshed with the gear one, each gear two is fixed with a rotating shaft, one end of the rotating shaft passes through the lower bottom surface of the chamber one and enters the chamber two, three slag removal mechanisms are arranged in the chamber two, each slag removal mechanism is respectively fixedly connected to the rotating shaft.

[0005] The above-mentioned device for cleaning sediment in the bored pile hole is placed into the pile hole by the staff using a lifting device. The staff has no way of knowing the thickness of the sediment in the pile hole, nor the extent to which the sediment is cleaned by the cleaning device. In order to thoroughly clean the sediment in the pile hole, the cleaning device needs to be placed at the bottom of the pile hole for a long time, which results in low efficiency in cleaning the sediment in the pile hole by the cleaning device. Utility Model Content

[0006] In order to improve the cleaning efficiency of a cleaning device for pile hole sediment, the present application provides a device for removing sediment from a bored pile hole.

[0007] The present application provides a device for removing sediment from a bored pile hole using the following technical solution:

[0008] A device for removing sediment from a bored pile hole comprises a sealed tank, on which a vacuum pump connected to a cavity in the tank is provided, on which a bottom wall of the sealed tank is provided a plurality of telescopic rods parallel to the length direction of the sealed tank, and each of the telescopic rods is provided with a locking piece for locking the length of the telescopic rod, the bottom ends of the plurality of telescopic rods are commonly connected to a fixed frame, on which a plurality of suction heads are mounted, a bellows is provided in communication between each of the suction heads and the sealed tank, a drill bit is rotatably provided at the bottom of the fixed frame, and a motor for driving the drill bit to rotate is provided on the fixed frame, and a visual window is vertically provided on the side wall of the sealed tank, and a scale is provided on the visual window.

[0009] By adopting the above technical solution, the staff first adjusts the length of the telescopic rod according to the depth of the pile hole where the sediment is to be cleaned, and locks the telescopic rod with a locking piece, then starts the motor, inserts several telescopic rods on the cleaning device into the pile hole, and the output shaft of the motor rotates to drive the drill bit to rotate synchronously, so that the drill bit breaks up the accumulated or even compacted sediment until the bottom wall of the sealed tank touches the ground. At this time, the vacuum pump is started, and the suction head sucks the scattered sediment into the sealed tank through the bellows. At this time, the sediment can be observed entering the sealed tank through the visual window. After the cleaning device absorbs the sediment for a certain period of time, the vacuum pump is turned off, and the volume indication of the scale on the visual window is observed at this time, and then the vacuum pump is started again to suck again, and the volume indication of the scale on the visual window is observed to increase. If there is no change, it means that the sediment in the pile hole has been cleaned up at this time, so that the staff can find the cleaning status of the sediment in time, thereby improving the cleaning efficiency of the cleaning device for the pile hole sediment.

[0010] Optionally, each of the telescopic rods comprises a telescopic sleeve fixedly arranged on the bottom wall of the sealed tank and a telescopic sleeve rod slidably sleeved in the telescopic sleeve, and each of the telescopic sleeve rods is electroplated with scale marks along its length direction.

[0011] By adopting the above technical solution, the scale markings on the telescopic sleeve rod improve the accuracy of workers in adjusting the length of the telescopic rod.

[0013] By adopting the above technical solution, the latch rod is inserted into the latch through hole to achieve a stable locking of the telescopic rod length. Not only is the operation simple, but the manufacturing process of the latch rod is simple, saving manufacturing costs, and it is also convenient for staff to adjust its length at any time.

[0014] Optionally, the drill bit is configured in a conical shape.

[0015] By adopting the above technical solution, the drill bit is set in an inverted triangular cone, which is easy to insert into the sediment to break up the sediment, and also easy for the cleaning device to quickly contact the inner bottom of the pile hole, thereby improving the cleaning efficiency of the cleaning device for the pile hole sediment.

[0016] Optionally, a plurality of pointed cone blades are arranged on the side wall of the drill bit facing the bottom of the pile hole.

[0017] By adopting the above technical solution, the arrangement of several pointed cone blades facilitates the drill bit to break up larger particles in the sediment during the rotation process of breaking up the sediment, thereby reducing the possibility of the suction head being blocked by larger sediment particles when absorbing the sediment.

[0023] By adopting the above technical solution, the setting of the slag discharge port makes it convenient for the staff to dump the sediment absorbed in the sealed tank. At the same time, the setting of the sealing strip and the baffle ensures that the sealed tank still maintains good sealing after the sediment is dumped.

[0024] Optionally, a handle is provided on the top of the sealed can for easy carrying.

[0025] By adopting the above technical solution, the provision of the handle improves the convenience for the workers to lift the cleaning device into the pile hole to remove the sediment.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The staff first adjusts the length of the telescopic rod according to the depth of the pile hole where the sediment is to be cleaned, and locks the telescopic rod with a locking piece, then starts the motor, inserts several telescopic rods on the cleaning device into the pile hole, and the output shaft of the motor rotates to drive the drill bit to rotate synchronously, so that the drill bit breaks up the accumulated or even compacted sediment until the bottom wall of the sealed tank touches the ground. At this time, start the vacuum pump, and the suction head will suck the broken sediment into the sealed tank through the bellows. At this time, the sediment can be observed entering the sealed tank through the visual window. After the cleaning device absorbs the sediment for a certain period of time, turn off the vacuum pump, observe the volume indication on the scale on the visual window, and then start the vacuum pump again to re-absorb, and observe whether the volume indication on the scale on the visual window increases.

If there is no change, it means that the sediment in the pile hole has been cleaned up at this time.

[0039] Reference Figure 1 and Figure 2 The dust collection assembly 3 includes a vacuum pump 31, a bellows 32 and a suction head 33. The vacuum pump 31 is fixedly arranged on the top of the sealed tank 1 and is connected to the inner cavity of the sealed tank 1. In this embodiment, four bellows 32 are taken as an example. The four bellows 32 are fixedly connected and arranged at the bottom of the sealed tank 1.
