Combined device for safety protection for steel casing of cast-in-place pile, and construction method

Abstract

The invention provides a combined device for safety protection for a steel casing of a cast-in-place pile. The combined device for safety protection for the steel casing of the cast-in-place pile comprises a steel ring, a main panel and a hinge element, wherein the centers of the steel ring and the steel casing of the cast-in-place pile are coaxial; the main panel is arranged on the steel ring; and the hinge element is arranged on the curved surface of one side of the steel ring. The invention further discloses a construction method of the combined device for safety protection for the steel casing of the cast-in-place pile. The combined device for safety protection for the steel casing of the cast-in-place pile effectively guarantees the production safety of working personnel while providing an effective working plane; the combined device is convenient to detach and install, high in turnover efficiency, and capable of lowering the production cost; construction for cast-in-place piles with pile hole diameters in a certain range can be adapted through an adjustment bolt, the matched combined device can further be provided to meet different steel casing needs and different field needs, and high flexibility and applicability are achieved.

Description

technical field [0001] The invention belongs to the construction fields of civil construction, industrial construction, bridges, etc., and in particular relates to a steel casing safety protection combination device for cast-in-situ piles and a construction method. Background technique [0002] At present, in the construction process of cast-in-situ piles, the method of setting steel casings on the upper part of the pile holes is often used to facilitate the control of the pile body position and prevent the displacement deviation of the pile body. The pile diameter of cast-in-place piles in larger projects will exceed 1m, while the steel casing of cast-in-place piles is generally only required to be 300mm-500mm above the ground, which is significantly lower than the safety height requirements of temporary protective railings. [0003] During the construction process, operators need to be close to the steel casing to measure the depth of the hole, disassemble the concrete pum...

AI Technical Summary

Problems solved by technology

Since the operator has no effective operating surface when the pile diameter is large, the safety protection cannot meet the requirements, causing the operator to easily slip into the pile hole, and the safety guarantee factor is low, which seriously affects the safety of personnel.

Moreover, during the construction process, the ground around the cast-in-situ pile steel casing is wet and slippery. During construction in winter, ice around the steel casing may occur from time to time, which increases the safety risk of workers falling into the pile hole.
