Problems solved by technology
However, this construction method has the following problems: when there are existing and newly-built electrified railway equipment distributed within the construction scope, such as catenary, and the catenary is just above the cover plate, since the boom of the crane is usually very high, it is different from the The distance between catenaries cannot meet the requirements of the catenary limit of 2m stipulated in the electrified railway safety code, so this method cannot be used for safe construction

Embodiment Construction
[0025] The construction method for replacing the culvert cover plate under the charged condition of the railway catenary provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] Such as figure 1 — Figure 7 As shown, the construction method of replacing the culvert cover plate under the electrified condition of the railway catenary provided by the invention comprises the following steps carried out in order:
[0027] 1) First determine the area affected by the replacement of the cover plate. If there are old cover plates 1 to be replaced under the two parallel existing lines in the affected area, take the outer part of any existing line as the operating side 2, close to the operating side The existing line on side 2 is used as the inner line 3, and the existing line away from the operating side is used as the outer line 4; if there is only one existing line in the affected area and the...

The invention provides a construction method for replacing culvert a cover plate under railway catenary charged conditions. The construction method comprises the steps of installing a gantry crane at a construction site, blocking an existing line under influence, dismounting old cover plate, discarding the old cover plate externally, replacing a new cover plate, restoring the existing line and the like. The construction method for replacing the culvert cover plate under the railway catenary charged conditions has the following advantages that in the whole construction period, the catenary has no power outage, normal operation of the existing line can be guaranteed, meanwhile, the cover plate replacement and construction process can be safely and quickly completed, the safety is high, the practicability is high, and standard requirements can be met.
Description
technical field [0001] The invention belongs to the technical field of railway culvert construction, in particular to a construction method for replacing a culvert cover plate under the charged condition of a railway catenary. Background technique [0002] Railway culverts refer to drainage channels or water passages under the subgrade in order to allow the railway to pass smoothly without hindering traffic during the construction of railway projects. According to the structural form, railway culverts can be divided into circular pipe culverts, arch culverts, slab culverts and box culverts. The cover culvert is mainly composed of cover plate, culvert platform and foundation. As we all know, when the cover plate has been used for a long time, it will develop damage and need to be replaced at this time. At present, the commonly used construction method of demolition and replacement is to first block the existing railway above the railway culvert and remove it, then use a cra...
