Embodiment Construction

[0032] This specific embodiment discloses a prefabricated assembly device for quickly improving the bearing capacity of a culvert, such as image 3 As shown, it includes a top plate 31 and flanges 32 on both sides of the top plate. The top plate 31 is used to be installed on the top of the culvert 1, and the flange 32 is used to be installed on both sides of the culvert 1. The dimensions of the top plate 31 and the flanges 32 are based on the size of the culvert 1. The size is prefabricated, the thickness of the top plate 31 can be designed according to the stiffness according to the increase of the design load, and the height of the flange 32 is mainly a fixing device to prevent the top plate 31 from torsion. Such as figure 2 As shown, the prefabricated assembly device 3 also includes a cushion 2 , wherein a part of the cushion is installed between the roof 31 and the culvert 1 , and the remaining cushion is installed between the flange 32 and the culvert 1 . This can buffe...

Abstract

The invention discloses a prefabricated assembly device for rapidly increasing culvert bearing capacity, comprising a top plate and flanges on both sides of the top plate, the top plate is used for mounting on the top of the culvert, the flanges are used for mounting on both sides of the culvert, and the dimensions of the top plate and the flanges are prefabricated according to the dimensions of the culvert. The invention also discloses a method for strengthening a culvert by adopting the prefabricated assembly device. The invention excavates part of the culvert to cover soil, not all of it; the reinforcement position is outside the culvert, not inside; the construction difficulty is low, the construction efficiency is high, does not need to enter the narrow culvert, greatly enhances the culvert's bearing capacity; the construction process of the invention is all on the outside of the culvert, and the bad construction environment of the culvert sewer pipe is avoided. The prefabricatedassembly device of the invention is integrated with the culvert after being strengthened, and does not need to be dismantled; the invention can greatly reduce the deflection deformation of the top ofthe culvert.

Description

technical field [0001] The invention relates to the field of culvert reinforcement, in particular to a prefabricated assembly device and a method for reinforcing a culvert. Background technique [0002] Culverts are drainage channels built under the roadbed and built below the road surface. The function of the culvert is to quickly remove the surface water along the highway to ensure the safety of the roadbed. As one of the important components of highway, culverts account for a large proportion in highway engineering and are an important part of highway engineering. [0003] With the increase of the operating life of the culvert, culvert leakage and erosion diseases have appeared due to the environment, load, and foundation deformation, which have affected the normal use and long-term performance of the culvert. When the originally designed load level is not enough for the current design requirements, it is necessary to quickly increase the bearing capacity of the existin...
