Embodiment Construction

[0022] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0023] a. Select a pre-paved site:

[0024] a.1 When the conditions of the construction site are good, the construction platform shall be filled outside the shoulder of the existing railway line insertion position, and the control piles shall be measured and placed on the platform according to the design insertion position, and the crossover line pre-laying shall be carried out strictly according to the control piles;

[0025] a.2 When the construction site is narrow and there are pull-out lines and safety lines, optimize the railway transportation plan in conjunction with the railway bureau, and give priority to occupying the existing lines for pre-paving if the transportation is not affected;

[0026] a.3 When there are existing equipment such as catenary poles and hard beam steel columns, formulate a transition plan for equipment relocation;

Abstract

The invention discloses a railway existing double crossover integral insertion and pavement construction method. The method comprises the following steps that 1, a pre-paving site is selected; 2, a double crossover is paved in advance, and control piles on the two sides of the double crossover are rechecked and accepted; 3, the double crossover is reinforced; and 4, double crossover sliding ways are arranged, the double crossover is integrally inserted and laid in place, an existing line in the inserting range is detached according to the design position in the skylight point, a ballast bed iscleared, the double crossover is slowly and transversely moved forwards, and the force of each part is guaranteed to be uniform. Compared with railway existing double crossover disintegration insertion and pavement, double crossover integral insertion and pavement is adopted, so that the number of the skylights is saved, the influence on normal transportation of the railway is reduced, the construction period is short, the efficiency is high, the overall structural size of the double crossover after being inserted is good, the diseases are few, the later maintenance cost is greatly reduced, the railway transportation is safe and reliable, the economic benefit is obvious, and the method can be widely popularized and used.

Description

technical field [0001] The invention relates to a construction method for inserting and laying turnouts of existing railway lines, in particular to a construction method for integrally inserting and laying crossover lines of existing railway lines, and belongs to the field of railway track construction. Background technique [0002] Crossover is a track equipment that railway rolling stock can enter from one line and cross another line. It can shorten the length of the station and reduce the occupied area, so it is widely used in railway operations. The crossover line is generally composed of four groups of single or symmetrical switches and a group of rhombus crossovers. The plane form of the crossover line is related to the opening direction of the single-opening turnout at both ends. The plane form that is more commonly used is the crossover line set between two parallel lines, that is, two sets of left-opening and two sets of right-opening are arranged symmetrically. Acc...
