The invention discloses a plastic drainage structure for a seawall foundation soil layer and a construction method of the plastic drainage structure. The plastic drainage structure comprises a vacuum pumping tank and at least two plastic drainage plates, wherein the two adjacent plastic drainage plates are connected by transverse water delivery pipes; four-way valves are arranged on the transverse water delivery pipes; rubber cover plates are arranged on the top surfaces of the plastic drainage plates, and connected with the vacuum pumping tank by pumping pipes; every two adjacent rubber cover plates are connected by a connecting hose; a drainage pipe is arranged on the top surface of the vacuum pumping tank. The construction method of the plastic drainage structure comprises the steps of performing survey setting-out, mounting the plastic drainage structure, filling a sand gravel layer and laying a block stone cushion layer. The method can meet solidification and construction of the seawall foundation soil layers with different soft soil foundations; compared with the traditional solidification method, a plastic drainage system is more reliable; water in the soil layers can be rapidly pumped out; the solidification strength of the soil layers can be improved.
Description
technical field [0001] The invention relates to a plastic drainage structure for seawall foundation soil layer and a construction method thereof. Background technique [0002] With the rapid development of the economy in the southeast coast of our country, various forms of cross-sea passages have emerged as the times require. Compared with bridges and tunnels, building seawalls has the advantages of low cost, providing shelter for ships, and reasonable use of cuttings at both ends of seawalls to excavate stonework. [0003] In the coastal area, due to the influence of rivers flowing into the sea, the seabed is mostly silty soft soil layer, which has the characteristics of high water content, high compressibility, low strength, poor water permeability and thick soil layer. The long-term uneven settlement of backwater affects the firmness of the building. Therefore, the plastic drainage board consolidation method is more and more widely used. [0004] In the construction of...
