Embodiment 1

[0036] Embodiment 1: A construction method for integrally spreading a turnout, comprising the following steps:

[0037] Step 1, construction preparation: complete the pre-laying of the turnout, the welding flaw detection of the rail inside the turnout, and the combined engineering and electricity adjustment; polish the turnout, store the ballast under the pre-laid turnout; block the line.

[0038] Step 2, cutting the rail: cutting the rail with a cutting machine, so that the rail to be cut is separated from the original rail.

[0039] Step 3, remove the rails and sleepers: use an excavator to transport the cut rails and the sleepers at the bottom of the rails, and transport the rails and sleepers out of the site.

[0040] Step 4, track ballasting: After the line is removed and the old materials are transported out of the construction site, use an excavator to clean the ballast bed. The depth of the track bed is not less than 10cm, and the ballast is placed between the two line...

Abstract

The invention discloses a construction method of integrally pulling and laying a turnout. The construction method comprises the following steps: (1) preparing for construction; (2) cutting rails; (3)dismounting the rails and sleepers; (4) removing ballasts on tracks; (5) inserting the turnout; (6) adjusting the position of the turnout; (7) placing the ballasts on the tracks; (8) tamping the tracks; (9) performing combined adjustment of maintenance with telecommunication and signaling; (10) clearing a site; (11) operating a line. A replacing and laying device is utilized to hoist and transversely move the turnout, and an on-site commander monitors and controls the state of the device so as to ensure the normal operation of the replacing and laying device, reduce the manual pushing, save labor and facilitate the transverse movement of the turnout. A rail jack is utilized to finely adjust the turnout to reduce the installation error of the turnout so as to improve the construction quality of the turnout.

Description

technical field [0001] The invention relates to the construction field of railway turnout laying, in particular to a method for integrally laying a turnout. Background technique [0002] Turnout is a line connection device that enables rolling stock to transfer from one track to another. It is also one of the weak links of the track, and is usually laid in large numbers at stations and marshalling. [0003] The existing technology can refer to the Chinese invention patent whose authorized announcement number is CN106351093B. This patent discloses a construction method for inserting and laying 1 / 42 turnouts in the existing line interval. The second step is the construction steps of pre-assembled turnout: (1) bulk rail material; (2) line drawing square pillow; (3) loose parts; (4) assembly; (5) turnout welding; the third step , Preparations for the overall lateral movement of the turnout: (1) Complete the assembly and welding of the turnout on the pre-assembled platform, and ...
