Description

Technical Field

[0001] This utility model relates to the field of building construction equipment, and more particularly to a borehole covering device. Background Technology

[0002] Currently, in the foundation stage of engineering, after the rotary drilling rig completes the hole, before the steel reinforcement cage is placed down and concrete is poured in time, the hole is usually covered by a mesh of steel bars welded longitudinally and transversely. This wastes steel bars and welders, and the turnover efficiency is not high. Utility Model Content

The round rod slides in the round tube through the cooperation of the long sliding grooves and the long sliding rods, so that it can be used for drilling holes of multiple diameters. Therefore, multiple sets of cover plates with different diameters can be made to accommodate drilling holes of various different specifications.

[0013] A mounting plate is provided on the outer end face of the round rod. A through hole is provided on the mounting plate, and a fixing pin is provided through the through hole. The lower end of the fixing pin is pointed so that it can be easily inserted into the ground, and the upper end of the fixing pin is a metal end.

[0016] A locating pin is coaxially arranged on the upper side of the cylindrical platform. The upper end of the locating pin is a truncated cone. The center of the cover plate is provided with a locating hole that mates with the locating pin. When installing the cover plate, the cover plate is installed on the cross by mates with the locating pin through the locating hole. Then, the edge of the cover plate is fixed by the U-shaped clip. The truncated cone facilitates the installation and mating of the locating hole and the locating pin.

[0017] A handle is provided on the side of the cover plate, which facilitates the installation of the cover plate.

[0018] The beneficial effects of this utility model are: simple structure, convenient installation and disassembly, strong practicality, reusability, which effectively improves work efficiency, facilitates turnover, and avoids material waste. Attached Figure Description
