[0005] In order to make up for the above deficiencies, the utility model provides a cave plugger for bored pile construction in housing construction projects, aiming to improve the prior art in which a plugging plate blocks the entrance of an underground cave on the inner wall of a pile hole. However, the thickness of the plugging plate is relatively thick as a whole due to its peculiar shape and the clamping edge of the outer wall of the cave, which makes it inconvenient to subsequently install the steel cage into the interior of the pile hole for construction. At the same time, the inner wall of the cave is clamped by an arc-shaped clamping plate, and the contact surface is small, so it is easy to be squeezed and fall off and displaced when pouring concrete.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a karst cave plugger for bored pile construction of a building construction project, comprising an adjusting cylinder, a sealing plate being clamped on the front outer wall of the adjusting cylinder, a sealing mechanism being arranged on the adjusting cylinder, an auxiliary mechanism being arranged on the sealing mechanism, the sealing mechanism comprising a worm, one end of the worm being rotatably connected to the bottom inner wall of the adjusting cylinder through a bearing, a worm wheel being meshingly connected to the worm, a rotating rod being fixedly connected to the inner ring of the worm wheel, a fixed disk being fixedly connected to the rotating rod, a first hinged rod being hinged to the outer wall of one side of the fixed disk, a transverse semicircular disk being hinged to the end of the first hinged rod away from the fixed disk, a second hinged rod being hinged to the outer wall of one side of the fixed disk, and a vertical semicircular disk being hinged to the end of the second hinged rod away from the fixed disk.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, by arranging structures such as a worm, a worm wheel, and a rotating rod, different-sized karst caves are sealed and fixed on the inner wall, and the plugging plate is improved to block the opening of the underground karst cave on the inner wall of the pile hole. However, the thickness of the plugging plate is relatively thick as a whole due to its peculiar shape and the edge of the outer wall of the karst cave, which makes it inconvenient to install the steel cage inside the pile hole for construction later. At the same time, the inner wall of the karst cave is clamped by the arc-shaped clamping plate, and the contact surface is small, which is easy to be squeezed and fall off and displaced when pouring concrete.

[0016] 2. In the utility model, by providing installation ports, pull plates, arc blocks and other structures, the sealing plate can be easily separated for maintenance and replacement, which improves the deformation and aging of the sealing plate caused by long-term use but inconvenient replacement, affecting the sealing performance of the cave. At the same time, after the sealing plate is disassembled, the internal parts of the regulating cylinder can be easily checked and maintained, which improves the inconvenience of maintenance for personnel when problems occur with the parts of the sealing mechanism.
