Construction method for embedded guided way at orbit traffic engineering across

Abstract

The present invention discloses a construction method of the guided way at the level-crossing in embedded track traffic engineering, it aims at providing a construction method for reinforcing the guided way at the level-crossing to reduce the damage of guided way at the level-crossing caused by heavy trucks, protect the life of rail and protect the operation safety. It includes the following steps: measuring and releasing lines; preparing the guided way; construction of chemical anchor bolt; putting the guided way into groove; installing bolts insulation bearing plate around the bolts, installing iron buckle on the bolts insulation bearing plate, installing insulation buckle press plate between the iron buckle and the bottom of the guided way, tightening the screw cap to fasten the insulation buckle press plate, iron buckle and the insulation bearing plate; casting epoxy sand pulp, shelling-out the rail holding groove and two sides of guided way with P21 priming paint; casting epoxy resin. The construction method reinforces the guided way, can release the damage of guided way at the level-crossing caused by heavy trucks, protect the life of rail and protect the operation safety, and the method is easy to be operated.

Description

technical field [0001] The invention relates to a construction method, more specifically, relates to a construction method of a large level crossing embedded track traffic engineering guide rail. Background technique [0002] The embedded rail transit project is a brand-new urban rail transit project. This new type of traffic project is the first in China. The project adopts the guide rail of the TRANSLOHR system and the special turning turnout, and introduces the mature construction technology of the French LOHR company. Cut longitudinal concave grooves in the pavement to bury fixed guide rails, and the guide rails are fixed with epoxy resin instead of traditional subway fasteners. The guide rail is a guide rail with a special cross-sectional shape. Generally, the top of the rail is about 3mm higher than the road surface, and the traction current returns to the substation through the guide rail. There is no special design for level crossings in European countries, which is...

AI Technical Summary

Problems solved by technology

Since the entire line of rail transit is an open road, at level crossings, in addition to bearing the force of the guiding system, ordinary traffic loads and the loads of Translohr vehicle tires, trucks at major intersections frequently pass by, or even seriously overloaded. The rail also needs to bear the force of heavy trucks on it. If it is not reinforced, the guide rail is easily damaged, and it is difficult to guarantee the service life of the line, which will affect the safe operation of the line.
