Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an on-site soil cleaning device in a pile hole for a construction project. Background Art

[0002] Cleaning the soil in the pile hole at the construction site is an important part of pile foundation construction. It mainly involves cleaning the soil and impurities generated by excavation in the pile hole to ensure the stability and construction quality of the pile foundation. The pipe pile core cleaner is a device specially used to remove soil and gravel from the pile foundation. It is widely used in pipe pile construction in bridges, buildings, subways and other engineering construction. It uses the rotation of the spiral drill rod to throw out the soil and gravel in the pile hole, thereby realizing the soil cleaning operation.

[0003] When the pile core cleaning machine in the prior art cleans the soil in the pile hole, the soil thrown out of the pile hole will accumulate on the outside of the pile hole on the surface. The operator needs to hold the shovel and gradually shovel the soil away from the pile hole to avoid backfilling of the soil. However, manual shoveling is inefficient and labor-intensive. During the shoveling process, some of the soil is easily loosened and falls into the pile hole. Therefore, an on-site pile hole cleaning device for construction projects is proposed to solve the above problems. Utility Model Content

Figure 5 As shown, when the bulldozer plates 115 are closed, the two bulldozer plates 115 together surround the periphery of the auger rod 203;

[0028] One end of the side wall of the mounting frame 107 is fixedly mounted with the motor 108, the output shaft of the motor 108 penetrates the interior of the mounting frame 107, and the output shaft of the motor 108 is fixedly connected with a threaded rod 109, and threads are provided on both sides of the outer wall of the threaded rod 109, and the threads on both sides of the outer wall of the threaded rod 109 face opposite directions, such as Figure 3 As shown, when the threaded rod 109 continues to rotate, the two sliders 110 are pushed in different directions by the threads;

[0029] The outer wall of the threaded rod 109 is threaded with sliders 110 on both sides. The top of the slider 110 is slidably connected along the top of the inner wall of the mounting frame 107. The bottom surfaces of the two sliders 110 are fixedly mounted on the moving rods 111 respectively. The upper end of the outer wall of each moving rod 111 is provided with a positioning hole 112. The upper end of the outer wall of each sleeve 114 is threadedly connected with a threaded shaft 116. The end of the threaded shaft 116 is plugged into the inner part of the positioning hole 112. Figure 3-Figure 4 As shown, the sleeve 114 is lifted along the surface of the moving rod 111, so that the threaded shaft 116 is aligned with the positioning hole 112, thereby facilitating the height locking of the sleeve 114 and the bulldozer blade 115;

[0033] When the device is in use, by pushing the push rod 105 and cooperating with the support wheel 106, the auger rod 203 is aligned with the pile hole, the motor 202 is started to drive the auger rod 203 to rotate, and the extended end of the hydraulic cylinder 102 pushes the lifting platform 201 to descend, so that the auger rod 203 is inserted into the pile hole and the internal soil is brought out to the surface. When the soil outside the pile hole forms a pile and needs to be cleaned, the motor 202 is stopped, and the loose threaded shaft 116 is twisted, the sleeve 114 falls, and the bulldozer 115 is pressed downward to insert it into the pile. Then the motor 108 is started again to drive the threaded rod 109 to rotate. At this time, the thread pushes the slider 110 to move linearly along the length direction of the installation frame 107, and the movement directions of the two sliders 110 are opposite, thereby driving the sleeve 114 and the bulldozer 115 to move in the direction away from the auger rod 203, and the bulldozer 115 pushes the pile to the outside of the pile hole;

[0034] Secondly, after the soil pile is away from the pile hole, the sleeve 114 is pushed upward, and the threaded shaft 116 is tightened and inserted into the positioning hole 112. Then the motor 202 is reversed to drive the two sliders 110 to reset along the inner side of the installation frame 107.
