Description

Technical Field

[0002] With the acceleration of urbanization, underground culverts, as key infrastructure for drainage, transportation and pipeline transportation, are facing increasingly severe challenges. High embankments, geological subsidence and complex hydrological conditions lead to a decline in the structural bearing capacity of culverts. The surge in urban traffic flow and environmental erosion exacerbate the aging of culverts. Traditional open-cut repair methods require traffic closure, which seriously disrupts urban operations and causes huge economic losses.

[0003] A search revealed Chinese Patent Publication No. CN209468705U, which discloses a structure for rapid reinforcement and repair of culverts using corrugated steel. This structure includes a corrugated steel structure and symmetrically arranged on both sides of the culvert to be repaired: a first soft soil base layer, a second soft soil base layer, and a reinforced concrete reinforcement layer. The reinforced concrete reinforcement layer is laid on the first and second soft soil base layers respectively. A first groove is pre-embedded in the reinforced concrete reinforcement layer within the first soft soil base layer, and a second groove is pre-embedded in the reinforced concrete reinforcement layer within the second soft soil base layer. The left side of the corrugated steel structure is mounted on the slide rail of the first groove via a first sliding support, and the right side of the corrugated steel structure is mounted on the slide rail of the second groove via a second sliding support. This invention solves the problems of cumbersome procedures and low construction efficiency in current road and bridge culvert construction, enabling rapid on-site construction, reducing manpower and equipment input, and ensuring normal road operation during construction.
