Construction method of non-collision throwing and filling of face protection gabion net bag

Abstract

The invention discloses a facing stone cage net bag bump-free dump filling construction method. The method comprises the steps that a stone cage net bag dump filling device is prepared; the stone cagenet bag dump filling device is placed on a barge deck, end steel slings located on the front side of an upper frame body are lifted to lifting hooks of crane equipment; the lifting hooks are lifted to pull up the upper frame body, a stone cage net bag is placed on an openable rolling bottom plate, and the upper frame body is placed down to be folded with the openable rolling bottom plate; the twoend steel slings are connected with the end lifting hooks, the steel slings are connected with the lifting hooks connected with an automatic hook disengagement device above the upper frame body, thelifting hooks connected with the automatic hook disengagement device and the two end lifting hooks are connected to the lifting hooks of the crane equipment through a three-leg chain; the stone cage net bag dump filling device is lifted and placed into water, the lifting hooks connected with the automatic hook disengagement device are disengaged, and the stone cage net bag slides down towards thesteel cylinder revetment direction. By means of the method, the stone cage net bag can accurately fall down to the position tightly attached to the steel cylinder revetment structure.

Description

technical field [0001] The invention relates to the technical field of offshore steel cylinder bank revetment structure construction, in particular to a non-collision throwing and filling construction method for face protection gabion net pockets. Background technique [0002] The steel cylinder revetment structure is an emerging technology in the construction of offshore artificial islands. The structure has the characteristics of fast construction, factory manufacturing, and low impact on the environment. It is the key technology to realize the rapid construction of artificial islands. However, because the structure has long-term anti-corrosion requirements in the sea, the outer wall of the steel cylinder is coated with an anti-corrosion coating. Since the steel cylinder bank revetment structure needs to be thrown and filled with various specifications of stones, gabion nets, etc. during the construction process, the coating on the surface of the steel cylinder bank revet...

AI Technical Summary

Problems solved by technology

It is not easy to arrange double-hook lifting equipment on a conventional crane ship for offshore construction, and this kind of structure adopts a split-down structure. When the gabion net bag falls, it falls directly below the spreader, because the overall size of the spreader is larger than the gabion net bag. Therefore, there is no guarantee that the gabion net bag structure can cling to one side of the steel cylinder revetment structure, and the spreader does not have the protective function of anti-corrosion coating on the steel cylinder revetment structure
