Structure and construction method of muddy coast sheet pile wharf

Abstract

The invention discloses a structure and a construction method of a muddy coast sheet pile wharf. The wharf is formed by combining a temporary causeway, a front sheet pile wall, a rear anchoring wall, an anchoring pull rod and a reinforcing soil body between the front sheet pile wall and the rear anchoring wall, wherein the temporary causeway is arranged on a muddy foundation, the front sheet pile wall and the rear anchoring wall penetrate through a dike body and a sludge layer to enter into a soil layer with high bearing capacity; a track pile foundation is piled; reinforcing the sludge between the front sheet pile wall and the rear anchoring wall by virtue of a cement mixing pile; throwing and filling rock mound behind the front sheet pile wall and the rock mound in front of the rear achoring wall; and connecting the front sheet pile wall with the rear anchoring wall by virtue of the anchoring pull rod, and finally combining the integral sheet pile structure. The sheet pile wharf constructed by the invention can be directly applied to the muddy foundation.

Description

technical field [0001] The invention relates to a coastal wharf, in particular to a wharf with a sheet pile structure and a corresponding construction process. Background technique [0002] With the development of my country's waterway transportation, the site selection and construction of new ports have to expand towards the muddy coast. Breakwaters are often used in the construction of port areas on silt coasts, and the dug-in type harbor basin is the main type. In order to increase investment benefits, it is necessary to expand the land area of ​​the port area and make full use of the water area of ​​the harbor basin. Therefore, full hall layouts are often used in such port areas. . In the full hall layout, the structure type that saves the area of ​​the harbor basin and increases the land area most should be the sheet pile structure. However, the traditional sheet pile wharf structure has a narrow scope of application, and is only suitable for sites with small tonnage ...

AI Technical Summary

Problems solved by technology

[0003] (1) The friction angle of the silt is very small, and a huge horizontal force is generated with the increase of the height difference of the filling, resulting in excessive bending moments of the curtain sheet pile and the front wall of the sheet pile;

[0004] (2) The shear strength of the silt is low, and the blind sheet piles cannot play the role of a blind, and the silt can bypass the blind piles and act on the front wall;
