Integral ballast bed lateral restraining device

Abstract

An integral ballast bed lateral restraining device belongs to the field of rail traffic, is suitable for reinforcing a heavy-duty or high-speed ballast bed structure, and solves the problems that the existing ballast bed structure has insufficient lateral restraint, insufficient vertical and horizontal resistance and short ballast bed maintenance period. First to fourth left connecting pieces (a1,a2,a3 and a4) are prefabricated at the lower end of the ballast stopping surface of a left integral reinforced concrete baffle plate (4); the first to fourth internal thread sleeves (c1,c2,c3 and c4) are prefabricated at the lower end of the ballast stopping surface of a right integral reinforced concrete baffle plate (2); and first to fourth right connecting pieces (b1,b2,b3 and b4) are in threaded connection with the first to fourth internal thread sleeves respectively. When the integral ballast bed lateral restraining device is in use, the end rings at one ends of first to fourth epoxy resin steel wire ropes are inserted into the holes of the first to fourth left connecting pieces and fixed through bolts and nuts; and the end rings at the other ends of the first to fourth epoxy resin steel wire ropes are inserted into the holes of the first to fourth right connecting pieces and fixed through bolts and nuts.

Description

technical field [0001] The invention relates to a reinforcing device for ballasted track bed, which belongs to the field of rail transportation. It is suitable for the reinforcement of heavy-duty or high-speed ballast bed structures. Background technique [0002] Ballasted track is an important part of rail transit structure. The disadvantages of ballasted track structure maintenance are: [0003] 1. In high-speed railways, especially in bridges and tunnels, the vibration is strengthened, and the lateral restraint is insufficient. The ballast is easy to fluidize, collapse, and the geometric size changes, resulting in a short maintenance cycle of the ballast bed. [0004] 2. For heavy-duty lines, due to the huge dynamic effect of the train and insufficient lateral restraint, the ballast particles are easily broken and pulverized, resulting in increased maintenance costs; especially in curved sections, the ballast bed has insufficient vertical and lateral resistance, and the ...
