Description

Technical Field

[0001] The present invention relates to the technical field of plastic-steel sheet piles, and in particular to an ecological plastic-steel sheet pile component and an ecological plastic-steel sheet pile. Background Art

[0002] Plastic steel sheet pile is a new type of water conservancy material, which can be used for river bank protection, waterway bank protection, hydraulic construction anti-seepage and other projects. Plastic steel sheet pile is a high molecular resin polymer, which performs well in corrosion resistance, UV resistance, corrosion resistance, weather resistance, oxidation resistance, ant resistance, frost resistance and high temperature resistance. Plastic steel sheet pile has strong tensile strength, compressive strength, bending strength, and strong impact resistance. The material composition of plastic steel sheet pile is stable, does not contain heavy metal substances and various plasticizers, is not affected by climate and water quality, has anti-pollution properties, and has no toxic and harmful substances. The construction is convenient and fast, occupies less land, and has no maintenance cost in the later stage. It provides an economic and environmentally more optimized option for river and water environment management. Traditional plastic steel sheet piles have no water-permeable and air-permeable holes, and have good anti-seepage properties, but at the same time they also block the connectivity between groundwater and surface water, and block the replenishment and discharge relationship between groundwater and surface water. In order to solve this technical problem, some solutions open circular holes in the plastic steel sheet piles to open up the connection between groundwater and surface water. However, this solution will not only reduce the tensile, compressive and bending strength of the plastic steel sheet piles, but also easily cause pipe bursts and soil erosion, seriously affecting the safety of the river.
