Abstract

The invention discloses an end thorn area reinforcing structure and a construction method. The end thorn area reinforcing structure comprises n-shaped end thorns; a first shield steel wall is horizontally arranged below main end thorns of the n-shaped end thorns, and the top of the first shield steel wall is connected with bottoms of the main end thorns through implanted reinforcing ribs; a secondshield steel wall and a third shield steel wall are arranged on a left side and a right side of the first shield steel wall, and reinforcing meshes are woven in the first shield steel wall, the second shield steel wall and the third shield steel wall and permeation-expansion type self-compacting concrete is filled; and the reinforcing meshes and the reinforcing ribs in the first shield steel wall, the second shield steel wall and the third shield steel wall are connected into a whole. According to the end thorn area reinforcing structure, the n-shaped end thorns are connected with the first shield steel wall, the second shield steel wall and the third shield steel wall through the reinforcing ribs, the reinforcing meshes and the permeation-expansion type self-compacting concrete, the original n-shaped end thorns are changed into inverted T-shaped end thorns, a track structure and a roadbed are well fixed together, and a reinforcing effect is better achieved.

Description

technical field [0001] The invention relates to the technical field of ballastless track, in particular to a reinforcement structure and a construction method for an end stab area of ​​a ballastless track. Background technique [0002] In recent years, my country's high-speed railway has developed rapidly. High-speed railway has the characteristics of high ride comfort and high stability. To achieve this goal, my country's high-speed railway lines generally adopt ballastless track structure. Compared with other track structures, ballastless track structure has Strong integrity, high stability and good durability. The anchoring structure behind the CRTS Ⅱ slab track platform consists of friction plates, small end spines, main end spines and transition plates. Two layers of geotextiles are installed on the surface of the friction plate to isolate it from the base plate, and water seepage bricks are installed behind the abutment to isolate it from the abutment, and are consolid...
