Abstract

The invention discloses a culvert structure adopting HDPE winding reinforced pipe and foam concrete, which comprises a culvert foundation, a culvert pipe, and filling bodies located on both sides and above the culvert pipe. The filling body is a foam concrete filling body; A HDPE winding reinforced pipe, an annular steel belt is wound on the inner side of the connection between two adjacent HDPE wound reinforced pipes, an anti-seepage sealing structure is arranged between the annular steel belt and the HDPE wound reinforced pipe, and a sealing strengthening device is arranged on the annular steel belt. The culvert structure has light weight and low requirements on the bearing capacity of the foundation, which can effectively solve the problems of uneven settlement of culverts and collapse of culverts. Suitable for corrosive and abrasive environmental conditions. The invention discloses a construction method of a culvert structure. Step 1: culvert pipe foundation construction; Step 2: culvert pipe installation; Step 3: Filling body construction; Step 4: Road surface construction. In this construction method, foam concrete is used as filling material, and the filling compaction link of vault and culvert side is canceled.

Description

technical field [0001] The invention belongs to the technical field of highway culvert structures, in particular to a highway culvert structure and a construction method using HDPE winding reinforcing pipes and foam concrete. Background technique [0002] In the domestic highway and railway construction, culverts occupy a large proportion. At present, most culverts are designed with reinforced concrete or masonry structures. The culvert masonry has a large amount of work, complicated construction and long construction period. Under complex geological conditions, foundation treatment and foundation engineering account for a large amount of engineering, making construction difficult. Although the round pipe culvert has the advantages of good cross-sectional stress conditions and strong integrity, but there are many longitudinal joints in the culvert, and the ability to adapt to the deformation of the foundation is poor. When the foundation is unevenly deformed, the pipe join...
