Construction method of octahedral wave-breaking block

Abstract

The present invention provides a construction method for an octahedral wave-breaking block, which significantly improves the production and installation efficiency of special-shaped wave-breaking blocks. By designing a casting mold with movable side molds and top molds, a continuous and efficient prefabrication process is achieved, which speeds up the overall construction progress. In particular, for the potential safety hazards that may be encountered during the flipping process, a hoist with a damper function is used to effectively alleviate the violent vibration caused by the center of gravity shifting, ensuring operational safety and stability. This method not only improves work efficiency, but also greatly reduces construction risks, and solves the problem that during the construction of traditional octahedral wave-breaking blocks, when the center of gravity shifts, the entire hoisting vehicle will vibrate violently, thereby affecting the construction efficiency.

Description

Technical Field

[0001] The invention relates to the field of construction of special-shaped wave-breaking blocks, and in particular to a construction method of an octahedral wave-breaking block. Background Art

[0002] With the development of the marine economy and the acceleration of coastal urbanization, the protection of the coastline has become increasingly important. As one of the key structures in seawall construction, wave-breaking blocks are mainly used to resist the impact of waves, reduce erosion, and provide necessary protection for infrastructure such as docks and ports. Traditional wave-breaking block construction methods usually use on-site casting or prefabricated components transported to the construction site for installation, but these methods have certain limitations.

[0003] The continuous operation capacity during pouring is poor, so a mold that can be repeatedly and continuously poured is needed to speed up the construction process. And because of its special octahedral structure, there is a momentary shift in the center of gravity when it is turned over. When the center of gravity shifts, it will cause the entire lifting vehicle to vibrate violently, and the next step can only be carried out after the vibration ends. There are great safety hazards and construction risks. Therefore, a construction hoist that can reduce the vibration caused by the center of gravity shift is needed to improve construction efficiency and reduce construction risks.
