Seawall protection structure

Abstract

The invention discloses a seawall protection structure. The structure comprises a plurality of thin-wall cylinders which are continuously arranged on a coastal bank line, the thin-wall cylinders are tightly attached to one another and are vertically arranged, and the depth of the thin-walled cylinders inserted into a soil foundation is at least more than half of the height of the thin-wall cylinders. The seawall protection structure combines the advantages of a gravity type structure and a pile foundation structure, a thin-walled cylinder structure is utilized, the thin-walled cylinders are inserted into the soil foundation to be fixed, compared with a traditional seawall structure which is easier to damage, the seawall protection structure has excellent shear resistance, anti-skid and anti-washing capabilities, and the seawall protection structure is simple and convenient to construct and high in popularization value in coastal regions.

Description

technical field [0001] The invention relates to the technical field of coastal protection engineering, in particular to a seawall protection structure. Background technique [0002] In order to resist natural disasters such as typhoon surges and protect the lives and properties of coastal people, seawalls, as the most direct and effective coastal defense engineering measures, have been widely used in coastal areas at home and abroad. Most of the currently used seawall structures are trapezoidal sections, using local materials, using sand as the embankment material, and adding rigid surface protection structures such as concrete or masonry on the seaside; at the same time, in order to prevent the loss of sand, sand A layer of geotextile is placed between the rigid protective surface. [0003] When the giant waves caused by typhoons in the coastal area propagate to the shore, the huge pressure load caused by the standing waves can easily crack the rigid armor surface, resulti...

AI Technical Summary

Problems solved by technology

[0003] When the huge waves caused by typhoons in the coastal area propagate to the shore, the huge pressure load caused by the standing waves can easily crack the rigid armor surface, resulting in the loss of embankment sand. The poor shear resistance between layers is also one of the reasons, and some dike sections are filled with loose powder and fine sand, the dike body is loose, and the anti-sliding stability is very poor, which seriously endangers the life and property safety of the people in coastal areas.
