Problems solved by technology

This construction method is not only easy to damage the concrete surface, but also easy to damage the formwork. At the same time, due to the underwater environment, the operators are affected by unfavorable factors such as low visibility, water buoyancy and resistance, and the demolition speed is slow. The construction intensity is high and the work efficiency is low. , not safe

Abstract

The invention discloses an underwater concrete template stripping device which comprises an integral template, wherein a screw rod is arranged on the integral template through a base, one end of the screw rod is movably connected with a steel sleeve, the steel sleeve is fixedly connected with a steel panel, the steel panel is embedded and installed on the working surface of the integral template, and the working surface of the steel panel is level with the working surface of the integral template. The invention provides the underwater concrete template stripping device and method. By adopting the structure and the method, an operator operates the screw rod to drive the steel sleeve to move, the steel panel drives the underwater integral template to separate from the concrete surface under the counter force by using the concrete surface as a fulcrum, thus the underwater template is stripped. The underwater concrete template stripping device provided by the invention has the advantages of being simple and convenient for operation, reducing labor intensity, being high in template stripping speed and working efficiency, being beneficial to safety construction, ensuring template integrity, and increasing template stripping efficiency without influencing pouring quality.

Description

technical field [0001] The invention relates to the field of underwater concrete formwork construction, in particular to an underwater concrete formwork removal device and method. Background technique [0002] Underwater concrete projects often use large-scale overall formwork construction, and are installed and dismantled underwater, which is more difficult to construct than underwater construction. At present, the underwater formwork removal mostly follows the method of water (dry land) formwork removal, mainly by selecting an appropriate prying point on the joint surface between the formwork and concrete, and slowly prying the formwork open with a crowbar. This construction method is not only easy to damage the concrete surface, but also easy to damage the formwork. At the same time, due to the underwater environment, the operators are affected by unfavorable factors such as low visibility, water buoyancy and resistance, and the demolition speed is slow. The construction ...
