Strengthening method of high polymer grouting and flexible revetment of coral reef island airport revetment

Abstract

The invention discloses a strengthening method of a high polymer grouting and flexible revetment of a coral reef island airport revetment. High polymer is injected into materials such as coral sand or coral stone, a three-dimensional latticed structure is formed by a high polymer material, and the coral sand or coral stone is wrapped to form a flexible strengthening body. The shape of the side, close to the sea, of the strengthening body is arranged to be arc, and the side, close to islands, of the strengthening body is arranged to be in erect type. After formed, the strengthening body has elasticity and belongs to the flexible revetment. After waves effect on the revetment, seawater flows along the arc side and returns to the sea after self energy dissipation. The invention further discloses a construction method of the revetment. By means of the strengthening method, the defect of traditional cement slip casting can be overcome; and the flexible revetment manner is adopted, so that the problems of wave prevention and leakage prevention are solved, the structure is simple, the construction is convenient, and the wide application scope is achieved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and particularly designs a polymer grouting self-dissipating flexible revetment for protection of coral islands and reefs and a construction method thereof. Background technique [0002] In recent years, the economy of various regions in our country has developed rapidly, among which the coastal areas have developed the fastest, and problems such as scarcity of land resources and increasing population have become more and more prominent, and some projects related to national interests and major livelihood issues There is almost no land to use, and the good coastline resources suitable for building ports and wharves are also dwindling. Therefore, people began to turn their attention to the ocean, which occupies most of the earth, to obtain more coastlines and land resources, leading to land reclamation and land reclamation. The utilization of natural islands and reefs is deve...

AI Technical Summary

Problems solved by technology

Compared with the gentle slope revetment, the steep slope revetment can be applied to different wave, water depth and foundation conditions, but this kind of revetment is not economical when the water depth is large

The second type is vertical revetment, but this kind of revetment has a large wave reflection and cannot self-dissipate energy, and the erosion in front of the wall is also serious, causing erosion

[0005] The traditional cement grouting method is usually used for revetment reinforcement. The disadvantage is that water is corrosive to cement grout, and the revetment of cement grouting is relatively brittle. It will produce impact cracks under long-term wave impact, which is not conducive to the anti-seepage of revetment. and stability
