A utility pole buried grouting device based on spiral multi-directional expansion

Abstract

The invention discloses a telegraph pole embedding and slurry spreading device based on spiral multidirectional expansion. A hollow screw hole is meshed through a meshing rotating head, thus a slurryspreading cylinder is settled downwards; cement is guided into the side wall of a round hole by a uniform distribution pipe; soil at the top of the round hole can be expanded outwards through an end widening device, so that the diameter of the round hole is increased; at the moment, the meshing rotating head is driven to rotate reversely, thus the slurry spreading cylinder moves upwards; the bottom of the slurry spreading cylinder is designed into a thickness expanding structure; the cement can be forcibly extruded to be attached to the side wall of the round hole through a thickness expandingface, the automatic mud laying function is achieved. More cement can be poured through the widened round hole, the firmness of the hole is improved, laid mud can be reinforced when the device is integrally used, the cement can be prevented from flowing into the bottom of the round hole, and a predetermined embedding depth of a telegraph pole in the later period is prevented from being affected.

Description

technical field [0001] The invention relates to the field of utility pole embedding, in particular to a utility pole embedding grouting device based on spiral multi-directional expansion. Background technique [0002] Before the utility pole is buried, it is necessary to dig a hole with drilling equipment, and then put the head end of the utility pole into the drilled round hole with the help of lifting equipment. The inner wall of the round hole needs to be grouted before use to avoid collapse. Phenomenon, the construction workers currently use wooden boards to surround and block, and then introduce mud. There are such problems in the use of existing grouting methods on the market: [0003] The existing grouting method is prone to deformation after the cement is introduced, and the wooden board is not easy to fix, and the bottom often leaks. After solidification, the depth of the round hole is cushioned, which affects the predetermined buried depth of the utility pole. The...

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a utility pole burying grouting device based on spiral multi-directional expansion to solve the problem that the existing grouting method is prone to deformation after the introduction of cement, the wooden board is not easy to fix, and the bottom Leakage often occurs, and the depth of the round hole is raised after solidification, which affects the predetermined buried depth of the utility pole. Therefore, it is urgent to invent a stable grouting device.
