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

Embodiment Construction

[0022] The reinforcement construction method of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] The construction schematic diagram of the reinforcement of the guide rail at the level crossing place of embedded rail transit project of the present invention is as shown in Figure 1 and Figure 2, and the resin product of this method mainly adopts the resin material of international EDILON company, is respectively Edilon Primer U90WB (being called for short U90) , Edilon Primer21 (referred to as P21) and Edilon Corkelast To (referred to as epoxy resin), according to the construction process of the embedded rail transit project, the three products are applied to the guide rail and the bearing groove in turn, and finally the guide rail is locked with resin. Concrete track bed. This construction method comprises the following steps:

[0024] 1. Measuring and setting out: Measure and set reinforce...

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...
