Method for positioning concrete turnout sleeper embedded sleeve pipe

Abstract

The invention relates to a method for positioning a concrete turnout sleeper embedded sleeve pipe, and belongs to a method for positioning the concrete turnout sleeper embedded sleeve pipe in railway track construction. The method aims to solve the problem that the method for positioning the concrete turnout sleeper embedded sleeve in the prior art is not easy to meet precision requirements and not convenient to use. The method comprises the following steps: designing the sizes of an upper positioning shaft, a lower positioning shafting and a positioning hole on a turnout sleeper mould shell substrate which are matched with the embedded sleeve pipe according to the shape and the inside diameter size of an embedded sleeve pipe, wherein one end of the upper positioning shaft is provided with threads, and one end of the lower positioning shaft is provided with an inner thread hole matched with the threads; in the process of turnout sleeper production, the embedded sleeve pipe is mounted on the mould shell substrate before concrete is poured into the turnout sleeper mould shell; the lower positioning shaft is penetrated into the sleeve pipe from the lower side of the positioning hole by penetrating the shell substrate; and the upper positioning shaft and the lower positioning shaft are helically connected after the upper positioning shaft is penetrated into the embedded sleeve. The method is suitable for positioning the embedded sleeve pipe in the process of the concrete turnout sleeper production.

Description

technical field [0001] The invention belongs to a positioning method for a pre-embedded casing of a concrete turnout sleeper in railway track construction. Background technique [0002] The concrete turnout sleeper is one of the main components in the turnout structure, and the fasteners are installed on the turnout sleeper by using the sleeves and bolts embedded in the turnout structure to install the turnout. [0003] With the development of domestic high-speed railways, turnouts have higher and higher requirements for the position accuracy of embedded casings in concrete turnout sleepers. At present, the casing pre-embedded positioning method and its device used in the domestic production of concrete turnout sleepers are not easy to meet the accuracy requirements of the casing hole distance of passenger-only turnout sleepers, and it is also inconvenient to use. Contents of the invention [0004] The purpose of the present invention is to solve the problem that the posi...
