Connecting device for burying pile casing and construction method

Abstract

The invention discloses a connecting device for burying a pile casing and a construction method. The connecting device comprises a connector connected with a rotary drilling rig, an oil pump cylinderlocated in the pile casing is connected to the lower portion of the connector, a first hydraulic oil pump and a second hydraulic oil pump are arranged at the upper end and the lower end of the oil pump cylinder correspondingly, a first tray moving in the axial direction of the oil pump cylinder is arranged at the bottom of the first hydraulic oil pump, a second tray moving in the axial direction of the oil pump cylinder is arranged at the top of the second hydraulic oil pump, a plurality of mechanical arms arranged in the radial direction of the oil pump cylinder are arranged between the firsttray and the second tray, and supporting plates abutting against the inner wall of the pile casing are arranged at the ends, away from the oil pump cylinder. When the first tray and the second tray move close to each other, the mechanical arms drive the supporting plates to expand in the radial direction, and when the first tray and the second tray move away from each other, the mechanical arms drive the supporting plates to contract in the radial direction.

Description

Technical field [0001] The present invention relates to the technical field of building construction, and more particularly to a connection apparatus and construction method of a burying cartridge. Background technique [0002] At present, the method of burying the cartridge in the industry is based on the geological conditions, in which the construction method is divided into two, the first is to directly be directly impeded, using a field excavator or vibration device directly to directly It is buryed, the second is to dig the burying method, and then apply the cartridge after 1 to 2 meters before proper excavation. [0003] In the process of the discharge cartridge, check whether the cartridge is vertical, and the vertical process is often checked, and there is a certain safety hazard, and there is a certain safety hazard, and if it is found that it is found, it should be corrected in time, however The correction process is a process of continuous debugging, which is generally...

AI Technical Summary

Problems solved by technology

[0003] In the process of lowering the protective tube, it should be checked whether the protective tube is vertical. In the process of checking the verticality, people often use a level or other instruments to check the verticality to check. There are certain potential safety hazards. If any deviation is found, it should be corrected in time. However , the correction process is a process of continuous debugging. Generally, the rotary drilling rig adjusts its moving distance through its own verticality automatic detection device. In this way, it is easy to cause insufficient accuracy and the hidden danger of damaging the casing.
