[0001] The utility model embodiment relates to the technical field of pile foundation construction, and in particular to an auxiliary cleaning tool for a cast-in-place pile conduit. Background Art
[0002] Cleaning of bored pile conduits is an essential part of pile foundation construction. During the bored pile construction process, if the concrete conduits are not cleaned properly, concrete will remain on the inner wall. When used again, the solidified concrete will hinder the injected concrete, resulting in more and more concrete remaining on the inner wall, which will affect the quality of the bored piles.
[0003] At present, workers usually use water pipes to clean the conduits. This method not only wastes water resources, but also requires special construction personnel to be responsible, which wastes manpower. In addition, the conduits are not cleaned thoroughly during manual cleaning, and concrete residues are easily left on the inner wall of the conduits, which in turn affects the next pouring of pile foundation concrete.

DETAILED DESCRIPTION
[0015] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0016] like Figure 1 to Figure 2 As shown, the embodiment of the utility model provides a cast-in-place pile conduit auxiliary cleaning tool, which is used for cleaning the internal concrete of the cast-in-place pile conduit, and includes a top bracket 1, a guide rod 2, an annular flushing bracket 3, a water pipe wheel 4, and a control line wheel 5;
[0017] A top bracket 1 is provided at the top of the cast-in-place pile conduit, and the top bracket 1 is used to fix the cleaning tool at the top of the cast-in-place pile conduit, so as to facilitate and quickly adjust the working environment and improve the working efficiency.
[0018] A water pipe wheel 4 is provided above the top bracket 1, and the water supply pipe 8 of the water pipe wheel 4 can be quickly retracted and released, so as to facilitate the stable water supply during the lifting and lowering process of the annular flushing bracket 3.
[0019] A water pump 14 is provided on one side of the cast-in-place pile conduit, and the water pump 14 is connected to the water pipe wheel 4 through an upper water pipe 15. The water pipe wheel 4 is separated from the water supply, which facilitates the movement of the module when adjusting the working environment.
[0020] A control wheel 5 is provided on one side of the water pipe disc 4, and a guide rod 2 is provided below the top bracket 1. A ring-shaped flushing bracket 3 is sleeved on the outer edge of the guide rod 2. The ring-shaped flushing bracket 3 is connected to the control wheel 5 through a rope 6. The control wheel 5 is operated to drive the rope 6 to control the lifting of the ring-shaped flushing bracket 3. The outer edge of the guide rod 2 is sleeved with the ring-shaped flushing bracket 3, so that the ring-shaped flushing bracket 3 moves up and down along the direction of the guide rod 2, thereby preventing the uncontrollable movement of the ring-shaped flushing bracket 3 due to the impact force of the water flow during the flushing process.
[0021] A flushing water inlet 7 is provided on the annular flushing bracket 3 , and the flushing water inlet 7 is connected to a water supply pipe 8 of the water pipe wheel 4 .
[0022] The annular flushing support 3 includes a diversion water pipe 9 , an annular water pipe 10 , a fan-shaped nozzle 11 , an annular support frame 12 , and an elastic steel wire grid 13 .
[0023] The water supply pipe 8 of the water pipe wheel 4 is connected to the diverter pipe 9 through the flushing water inlet 7, and the diverter pipe 9 is connected to the annular water pipe 10. A plurality of fan-shaped nozzles 11 are evenly distributed on the annular water pipe 10. The diverter pipe 9 is used to ensure the water pressure balance at various locations of the annular water pipe 10, so that the fan-shaped nozzles 11 can achieve a better flushing effect. The nozzle direction of the fan-shaped nozzle 11 is at an upward angle of 45° with the horizontal direction. The fan-shaped nozzle 11 at a horizontal angle of 45° upward provides downward force to prevent the concrete from having too much resistance to the elastic steel wire mesh 13, which cannot be moved under the action of gravity, and at the same time performs oblique flushing, which is convenient for controlling the lifting.
[0024] An annular support frame 12 is provided below the annular water pipe 10, and an elastic steel wire mesh 13 is provided on the outer edge of the annular support frame 12. The elastic steel wire mesh 13 is used to cut concrete, so that the concrete on the inner wall of the cast-in-place pile conduit has grooves, which is convenient for the fan-shaped sprinkler 11 to flush it.
[0025] The top bracket 1 is provided with a guide rod positioning groove 16, and the guide rod positioning groove 16 matches the structure of the guide rod 2. A latch can be provided on the guide rod 2 to fix the annular flushing bracket 3.
[0026] During operation, for the bored pile conduit which is placed vertically and is inconvenient for manual cleaning, the guide rod 2 can be inserted into the bored pile conduit, the guide rod 2 is sleeved with the annular flushing bracket 3 and fixed by a latch, the top of the guide rod 2 is cooperated with the top bracket 1 to be installed through the guide rod positioning groove 16, the top bracket 1 is installed with the water pipe wheel 4 and the control line wheel 5, the rope 6 of the control line wheel 5 is connected to the annular flushing bracket 3, the water supply pipe 8 of the water pipe wheel 4 is connected to the flushing water inlet 7 of the annular flushing bracket 3, the latch is pulled out, the lifting and lowering of the annular flushing bracket 3 is controlled by the control line wheel 5, the upper water pipe 15 of the water pump 14 is connected to the water pipe wheel 4, and flushing starts.
[0027] During the operation, the control wheel 5 must be properly waterproofed and leak-proofed.
[0028] Under the action of the fan-shaped nozzle 11, the annular flushing support 3 cuts the concrete on the inner wall of the bored pile conduit through the elastic wire mesh 13 to destroy its integrity, and then the fan-shaped nozzle 11 flushes it to improve the flushing efficiency.
[0029] The direction of the fan-shaped nozzle 11 can also be adjusted as needed to achieve a better flushing effect.
[0030] After the operation is completed, the annular flushing bracket 3 is raised to the top by the control wire wheel 5 and fixed by a pin, the connection between the rope 6, water supply pipe 8 and the annular flushing bracket 3 is released, the connection between the water pump 14 and the water pipe wheel 4 is released, and the integrated structure of the top bracket 1, water pipe wheel 4 and control wire wheel 5 is directly transported to the top of the next cast-in-place pile conduit where the guide rod 2, cast-in-place pile conduit, power supply and water supply have been installed for the next flushing step.
[0031] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
