Embodiment Construction
[0028] The present invention is introduced below by accompanying drawing.
[0029] In this application, it should be noted that the direction in which the culvert extends is defined as "longitudinal", and the direction perpendicular to the direction in which the culvert extends and extends horizontally is defined as "horizontal". In addition, it should be noted that the directional terms or qualifiers "upper" and "lower" used in the present invention are all for the referenced drawings. They are not intended to define the absolute positions of the parts involved, but may vary on a case-by-case basis.
[0030] According to the invention, a construction method for reinforcing a culvert is provided. According to the construction method of reinforcing the culvert, the corrugated plate is used to reinforce the culvert, the construction process is simple, the construction period is short, and the passage of local personnel and vehicles is not affected, and the construction cost is ...

The invention provides a construction method for reinforcing a culvert. The construction method comprises the steps that an existing road surface in the culvert is cut and excavated to the surface ofa foundation of an existing culvert, and concrete is poured to form a corrugated pipe culvert foundation; existing failure settlement joints are remediated, and drainage devices are arranged at the settlement joints on the bottom surface of a top plate of the existing culvert; corrugated plates are laid on the inner wall of the existing culvert, wherein the end parts of the corrugated plates are fixedly installed in the corrugated pipe culvert foundation; and grouting and backfilling are carried out between the corrugated plate and the inner wall of the existing culvert, wherein the corrugatedplates are assembled in pieces between an upper ring plate and plates and are assembled between a longitudinal upper ring and rings in an overlapping manner, and fixing pieces are adopted for installation to form a fixed connection.
Description
technical field [0001] The invention belongs to the technical field of bridge and culvert construction, and in particular relates to a construction method for reinforcing a culvert, in particular to a construction method for reinforcing a culvert by using a corrugated plate. Background technique [0002] With the rapid development of railway technology, the speed and load of railway trains continue to increase. Some railway culverts cannot withstand the high-speed operation and load of trains, and there are cracks, leaking reinforcement and water leakage and other diseases. [0003] The culverts with serious diseases need to be reinforced and rehabilitated. At present, the culvert scheme is usually used for renovation. The culvert scheme mainly includes the concrete culvert scheme and the corrugated plate culvert scheme. Among them, although the concrete culvert scheme is economical to a certain extent, its construction process is complicated and its construction period is ...
