Embodiment 1

[0041] (1) Process a plurality of steel cylinders 1 and a plurality of steel auxiliary grids 2, and then paste the rubber protective layer 3 on the lower wall of each steel cylinder 1 and the lower outer wall of each steel auxiliary grid 2 with superglue Above, the rubber protective layer 3 covers the entire surface of the steel cylinder 1 and the steel sub-grid 2 in the riprap area of ​​the front seaside area during installation, and the adhesive height of the rubber protective layer 3 is the same as the set riprap area. The riprap heights in the area are the same;

[0042] (2) Lower the steel cylinder 1 and the steel sub-grid 2 to the revetment position of the artificial island to be built, drive the lower part of the steel cylinder 1 into the seabed, and then insert the two sides of the steel sub-grid into two adjacent intervals. In the slot of a steel cylinder 1, the steel cylinder 1 and the steel sub-grid 2 are connected into one to form a revetment structural system;

Abstract

The invention discloses a construction method of an anti-corrosion coating protection structure of a steel cylinder bank revetment structure in riprap construction, comprising the following steps: processing a steel cylinder and a steel sub-grid, and then pasting a rubber protective layer on each steel cylinder with superglue on the lower wall of the cylinder and the lower outer wall of each steel auxiliary grid; lower the steel cylinder and the steel auxiliary grid to the bank revetment position of the artificial island to be built, and drive the lower part of the steel cylinder into the seabed; on the side of the backfill area The outer wall of each steel cylinder and steel auxiliary grid is covered with double-layer geotextile; transport and throw gabion net bag; throw backfill block stones outside the steel cylinder and steel auxiliary grid on the side of the backfill area and throw stone cage net bag outside Fill the block stones near the sea; use the floating crane to hoist and install the presser foot hollow squares on the gabion net bag; use the riprap boat to throw backfill block stones on the steel cylinder and steel sub-grid at the side of the backfill area at the same time and place them on the presser foot The outside of the hollow block is thrown and filled with block stones facing the sea. Adopting the method is helpful to realize the long-term anticorrosion of the steel cylinder revetment structure.

Description

technical field [0001] The invention relates to the field of offshore artificial island construction, in particular to a method for constructing an anti-corrosion coating protection structure of a steel cylinder revetment structure in riprap construction. Background technique [0002] It is an emerging technology in the construction of offshore artificial islands to use steel cylinders as the revetment structure, and then perform internal reclamation to build islands after the revetment is formed. The construction method has the characteristics of fast construction, factory manufacturing, and small impact on the environment. In the current known field, the steel cylinder revetment structures adopted are all temporary structures, and the steel cylinder revetment no longer plays the role of enclosure after the island is formed, so there is no excessive requirement on the service life of the structure. However, if the steel cylinder revetment structure involved is used as a pe...
