Culvert structure adopting high density polyethylene (HDPE) winding reinforcement pipes and foam concrete and construction method of culvert structure

Abstract

The invention discloses a culvert structure adopting high density polyethylene (HDPE) winding reinforcement pipes and foam concrete. The culvert structure comprises a culvert pipe foundation, culvert pipes and filling bodies located on the two sides and the upper portions of the culvert pipes. The filling bodies are foam concrete filling bodies. The culvert pipes comprise the multiple HDPE winding reinforcement pipes which are connected in an end-to-end mode in sequence. The inner side of the connecting position of every two adjacent HDPE winding reinforcement pipes is provided with an annular steel band in a winding mode. Seepage-proofing sealing structures are disposed between the annular steel bands and the HDPE winding reinforcement pipes. Sealing reinforcement devices are disposed on the annular steel bands. The culvert structure is small in self weight, low in requirement for foundation bearing capacity, capable of effectively solving the problems of differential settlement and cambering of the culvert pipes and suitable for the environment conditions of corrosion and abrasion. The invention discloses a construction method of the culvert structure. The construction method includes the steps of (1) culvert pipe foundation construction, (2) culvert pipe mounting, (3) construction of the filling bodies and (4) construction of a road surface. By means of the construction method, the foam concrete is used as a filling material, and the link of compacting the fillers on the arch apex and culvert sides is omitted.

Description

technical field [0001] The invention belongs to the technical field of culvert structures, and in particular relates to a culvert structure and a construction method using HDPE winding reinforcement pipes and foam concrete. Background technique [0002] In domestic highway and railway construction, culverts occupy a large proportion. At present, most culverts are designed with reinforced concrete or masonry structures. The culvert has a large amount of masonry, cumbersome construction and long construction period. Under complex geological conditions, foundation treatment and foundation engineering account for a large amount of work, making construction difficult. Although the circular pipe culvert has the advantages of good cross-section 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, it will cause the pipe joints t...

AI Technical Summary

Problems solved by technology

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
