Embodiment Construction

[0017] see figure 1 , figure 2 and image 3 According to the prior art, the structural composition of the ladder-shaped track includes: steel rail 1, buckle fittings 2, ladder-shaped sleeper 4 and "L" shaped concrete support 6; between the ladder-shaped sleeper 4 and "L" shaped concrete support 6 An "L"-shaped mating surface is formed between them. On the "L"-shaped mating surface, each segment of "L"-shaped vibration-absorbing parts composed of bottom damping pads 5 and side buffer pads 7 is arranged at intervals. The ladder-shaped sleeper is composed of left and right strips. It is composed of 3-shaped sleepers and intermediate connecting steel pipes. Nylon sleeves are embedded in the sleepers to install buckle accessories. Vibration noise reduction effect.

[0018] In the present embodiment, adopt following construction method for trapezoidal track:

[0019] First, before the ladder-shaped sleeper 4 is in place, the bottom and side of the ladder-shaped sleeper 4 are re...

Abstract

The invention discloses a construction method of a ladder-shaped track in urban track traffic, which is characterized by comprising the following steps of: firstly, before ensuring ladder-shaped sleepers in position, completely adhering parts located among sections of vibration reduction members by using cystosepiments according to the thicknesses the same with those of a bottom vibration reduction pad and a side cushion pad respectively at the bottom part and the side part of the ladder-shaped sleeper; hoisting the ladder-shaped sleepers adhered with the cystosepiments in position, arranging brackets to ensure that the ladder-shaped sleepers are erected by the brackets, installing buckle accessories on the ladder-shaped sleepers, and laying steel rails and arranging a rail state; then placing support concrete with a vertical mold; and after the placing of the support concrete is completed, manually removing the cystosepiments to form the ladder-shaped track in a floating state. In the invention, the whole track bed is integrally formed, the process is simple, the construction efficiency is high, the ladder-shaped sleepers can effectively float, and the performances of vibration reduction and noise reduction are effectively ensured.

Description

technical field [0001] The present invention relates to a kind of construction method, more specifically is the construction method of urban rail transit ladder-shaped track Background technique [0002] The ladder-shaped track is a new damping track structure that has appeared in recent years, such as figure 1 , figure 2 and image 3 As shown, its structural composition includes: rail 1, buckle fittings 2, ladder-shaped sleeper 4 and "L"-shaped concrete support 6; an "L" shape is formed between the ladder-shaped sleeper 4 and "L"-shaped concrete support 6 On the matching surface, on the "L" shaped matching surface, each section of "L"-shaped vibration damping parts composed of bottom damping pad 5 and side buffer pad 7 is arranged at intervals. The ladder-shaped sleeper is composed of left and right strip sleepers and middle connecting steel pipes 3. The nylon casing is pre-embedded in the sleeper to install buckle fittings. After the ladder-shaped ballast bed is formed...
