Embodiment Construction

[0015] Below in conjunction with embodiment the present invention is further described.

[0016] A construction technique for pouring concrete into a railway crossing, the construction steps of which are:

[0017] The first step: Excavation of the foundation pit; first remove the track, disassemble the line rails and sleepers, pile them up on site and arrange timely processing, excavate the foundation pit within the determined length, width and elevation of the crossing pavement, and use a level Repeatedly measure and proofread each control point of the excavated foundation pit;

[0018] The pavement elevation in the area of ​​the new pavement crossing should be 10-20mm higher than the design rail surface elevation, as the reserved amount for settlement (depending on the firmness of the foundation); the excavation width of the foundation pit is: panel width 3 meters + reserved amount 0.3 ~0.4m=3.2~3.4m, and at the same time, pay attention to ensure that it is on the same cent...

Abstract

The invention relates to a construction technology for forming a railway crossing by pouring of concrete. The construction technology comprises the following construction steps: firstly, excavating a foundation pit; then fabricating an integral mould on site; and finally, mixing concrete paste by adopting a filling machine. The obtained railway crossing of the structure is good in integrity, a road bed is stable, bearing pressure is high, the 'twist warp' phenomenon of a track, caused by mud pumping of the road bed and track settlement, is avoided, and operation security of a train is guaranteed; besides, a rim channel of the railway crossing is subjected to integral pouring, so that a 'pad derailment' accident caused by the fact that a rim channel of a steel rail is easy to deviate and run off is completely eradicated. Therefore, an automobile, a non-motor vehicle and pedestrians can be as steady and immovable as on a dry land when passing through the railway crossing, heavy load resistance is realized, the service life is long, one-step construction forming and maintenance-free using effect are achieved, and manpower and materials are greatly saved for an enterprise.

Description

technical field [0001] The invention belongs to the technical field of crossing construction design used by factories, mines and enterprises, and relates to a construction technique for pouring concrete into a railway crossing. Background technique [0002] At present, the types of railway crossing pavement used by local factories and mines include wooden sleeper plane crossing, wooden sleeper + steel plate plane crossing, rubber plate pavement crossing, concrete (stone) block pavement crossing, asphalt pavement crossing, integral prefabricated steel structure pavement crossing, and rail side-by-side structure Pavement crossings, integral reinforced concrete crossing slabs, etc., are common problems: the installation between crossing slabs and between crossing slabs and railway lines cannot achieve effective rigid fixed connection, poor stability, short service life, and high maintenance costs. Contents of the invention [0003] In order to overcome the above-mentioned tec...
