Resilient pad, mold and method for manufacturing open track bed

Abstract

The invention discloses an elastic cushion for manufacturing an open-type rail bearing groove roadbed. The cylindrical elastic cushion comprises an attaching surface I and an attaching surface II which are oppositely arranged; and the shape of the attaching surface I is fitted with the shape of a section of the end part of a sleeper. Through the adoption of the elastic cushion disclosed by the invention, one surface of the elastic cushion is connected to the sleeper, and the other opposite surface of the elastic cushion is used for connecting a mold plate for casting a roadbed; and the elastic cushion can be bended and compressed, so that the purpose that when the sleeper is obliquely arranged, the end part of the sleeper is still tightly attached to the mold plate can be met, the purpose that no matter whether the roadbed is cast in a straight section or a curve super-elevation section, after the mold plate and the elastic cushion are disassembled, an opening in a required shape is formed in the position of the original elastic cushion, at the end part of the roadbed in which a rail bearing groove of the sleeper is formed is guaranteed, and the defects that in the prior art, if a harmful layer is not removed, an opening is not formed in the rail bearing groove, besides, the harmful layer is thin, chipping is easy to generate, if the harmful layer is removed, secondary construction is required, the workload is large, the quality is not liable to guarantee, and time and labor are wasted are avoided.. The elastic cushion disclosed by the invention is simple in structure, convenient to use and low in cost.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an elastic pad, a mold and a method for manufacturing an open rail bearing channel bed. Background technique [0002] Ballastless track has the advantages of high stability, less maintenance and long service life, and is widely used in rail transit. As the country and society pay more and more attention to environmental protection and green development, the vibration reduction type developed on the basis of ordinary ballastless track Ballastless track has been widely used in urban rail transit, one of which is to set a vibration-damping layer on the sleeper. With the rapid development of my country's rail transit, there are more and more cases of urban rail transit, passenger dedicated lines, and high-speed railways connecting to densely populated urban areas. Rail vibration reduction measures are adopted in the above-mentioned higher-speed rail transit to reduce the impact ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the problem existing in the prior art that when manufacturing a ballast bed in a curved superelevation section, a harmful gap is formed between the end face of the sleeper and the template due to the inclination of the sleeper, and the concrete will fill these gaps when the concrete is poured in the subsequent sequence. A harmful layer is formed in the gap. After the formwork is removed, if the harmful layer is not removed, there will be no openings in the rail support groove, and the harmful layer is thin, and it is easy to fall off. If the harmful layer is removed, secondary construction is required, the workload is large, and the quality is not easy Guaranteed, time-consuming and labor-intensive problems, providing an elastic pad, mold and method for manufacturing open rail bearing groove track beds
