Example Embodiment

[0032] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0033] As shown in the drawings, the construction method of the present invention for the surface protection gabion net bag without bumping and filling includes the following steps:

[0034] (1) Preparation of a gabion net bag throwing and filling device. The gabion net bag throwing and filling device includes an upper frame 1 with an open bottom and a rectangular cross-section. The upper frame includes two rows of frames arranged in parallel on the left and right. The vertical support column of the frame body, each column of the frame body vertical support column includes a plurality of frame body vertical support columns 1-1 arranged in parallel and spaced apart from each other, and the top and the middle between the two adjacent frame body vertical support columns The top connecting beams 1-2 and the middle connecting beams 1-4 are respectively connected in t...

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...
