Problems solved by technology

The above phenomenon reduces the bearing capacity of the slab culvert, reduces the shear strength, and poor stability, and most of the waterproofing of the slab culvert has been damaged. Humid air and rain and snow erode the steel bars inside the slab, which makes the disease further develop, seriously threatening the safety of driving and affecting transportation. Production, need immediate remediation

Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing.

[0028] figure 1 An installation view of a corrugated plate assembly according to the present invention is shown. The following is based on figure 1 The reinforcement methods used for railway culverts are discussed in detail. The method includes the following steps. First, a foundation pit is excavated along the side wall on the inner side of the culvert, and the embedded part 1 is implanted on the bottom of the foundation pit. Then, a corrugated plate assembly 2 matching the shape of the culvert is arranged inside the culvert. Both sides of the corrugated plate assembly 2 are respectively fixedly connected with the embedded part 1 . Next, concrete is poured into the pit to form the foundation. Finally, fill the gap between the corrugated sheet assembly and the inner side of the culvert.

[0029] In a preferred embodiment, the foundation pit is excavated along the sid...

Abstract

The invention provides a reinforcing method for a railway culvert. The reinforcing method includes: a first step, digging a foundation pit along a lateral wall edge of an inner side surface of a culvert, and implanting a pre-buried member in a bottom surface of the foundation pit; a second step: arranging a corrugated plate assembly matching the shape of the culvert in the culvert, wherein two sides of the corrugated plate assembly are fixedly connected to the pre-buried member; a third step, pouring concrete into the foundation pit so as to form a foundation; and a fourth step, filling a gap between the corrugated plate assembly and the inner side surface of the culvert. In the method, the corrugated plate assembly is used to maintain the existing culvert; the flexure strength and the compressive strength of a corrugated plate are excellent, and then the corrugated plate assembly has high bearing capability, is excellent in resistance to earthquake, and can adapt to large sedimentation and deformation.

Description

technical field [0001] The invention relates to the technical field of post-reinforcement of culverts, in particular to a reinforcement method for railway culverts. Background technique [0002] Railway culverts are tunnels located under the railway subgrade. Railway culverts are used to quickly drain surface water along the railway to ensure roadbed safety. At the same time, it can be used as an overpass for people, livestock and vehicles, or as a water channel for farmland irrigation. The culvert is mainly composed of the cave body, foundation, end and wall. [0003] With the long-term high-density operation of trains, some diseases may appear in the culverts. For example, there are many cracks in the reinforced concrete cover plate and side wall of the culvert, and some steel bars have even been exposed. The settlement joints generally seep water, causing the surrounding concrete to peel off and expose the tendons, the side walls of the culverts are generally corroded...
