Embodiment Construction

[0037] About ballastless bed track laying

[0038] See Figure 1: Construction is carried out according to the following process:

[0039] The track laying unit is grouped sequentially according to the track laying direction: work car 1, auxiliary power car 2, sleeper rail transport car group 3 and locomotive 8.

[0040] 1. Preparation

[0041] The track laying unit must first reach the state of laying ballastless track.

[0042] (1) The locomotive 8 sends the track-laying unit to the ballastless bed to stop, and the locomotive 8 picks up and returns to the base; the unit is adjusted to the self-propelled state (as shown in Figure 1(a))

[0043] (2) 4m short rails are pre-laid, and the unit aligns itself; 10 sets of rail guides are installed every 5m, and there are four sets in total, and then a pair of rollers 9 are preset every 5m along the bearing groove of the ballastless ballast bed; (as shown in Figure 1(b))

[0044] (3) Unload the locking device of a pair of long rai...

Abstract

The present invention relates to a construction method for laying seamless line rail track by using CPG 500 seamless line long rail string track-laying machine unit. It is characterized by that it utilizes CPG 500 model seamless line long rail string track-laying machine unit to lay long rail track with 500 m by means of one-step operation, and has no need of other equipment, and its working efficiency is high and laying quality is good.

Description

technical field [0001] The invention relates to a construction method for laying seamless track. Background technique [0002] The length of the long rails welded in our bases is generally 25m to 250m or 300m; the length of the long rails welded in foreign bases is usually no more than 300m. The Hening Passenger Dedicated Railway under construction by China Railway No. 4 Engineering Bureau welded 100m steel rails into 500m long rails, and then used long rail laying units to lay 500m long rails at a time. It is the first time in foreign countries and China. [0003] The CPG500 seamless line long track laying unit currently being used in the construction of the Hening Railway is a special equipment capable of laying 500m long rails at a time. As a construction method for the track laying unit, the closest one is the SVM1000CH imported from Austria. Track laying unit. The SVM1000CH track laying unit can only lay ballasted bed tracks, and special equipment is required for the ...
