[0038] Application of Prefabricated Box Culvert in Yecheng-Moyu Highway Construction Project

[0039] (1) Project introduction: This project is located at the northern foot of the Karakorum Mountains in the Xinjiang Uygur Autonomous Region and the southern edge of the Tarim Basin. The route connects Yecheng in Kashgar, Pishan County and Moyu County in Hotan, with a total length of 227km.

[0040] The length of this reconstruction is 182km. The whole line adopts the secondary road standard. The project started in 2008 and was completed in 2010 with a construction period of two years.

[0041] (2) Application of results in the research stage: prefabricated box culverts, steel bellows culverts

[0042] (3) The project is divided into five contract sections. The fifth contract section is located in the farmland area, the surface is mostly fine-grained soil, and the bearing capacity of the foundation is low. Therefore, this time, the fifth contract section chose the higher part...

Abstract

The invention discloses a prefabricated assembled box culvert and a construction method thereof. The box culvert is in an assembled structure and consists of a reinforced concrete culvert body, wing walls, a foundation and deformation joints, wherein the culvert body of the box culvert is in an integral closed-type reinforced concrete framework structure formed by combining transition culvert joints, non-standard culvert joints and standard culvert joints. The culvert body and the wing walls adopt assembly and construction. By utilizing the prefabricated assembled box culvert, batch production can be performed in a factory, field assembly is realized, the construction progress of the culvert is accelerated, the construction period is shortened and the quality of the culvert is ensured. Therefore, the problems of long culvert construction period and difficult control on the quality during the current road construction can be solved.

Description

technical field [0001] The invention relates to a prefabricated box culvert and a construction method thereof. Background technique [0002] The box culvert used in the field of engineering and construction refers to the culvert built with reinforced concrete box-shaped pipe joints. Box culverts consist of one or more square or rectangular sections, generally made of reinforced concrete or masonry, but reinforced concrete is widely used. When the span is less than 4m, box culverts are used. For pipe culverts, reinforced concrete box culverts are An inexpensive alternative, the piers, upper and lower slabs are all poured in unison. [0003] The box culvert can be used for drainage, passing people and vehicles. The main components are reinforced concrete culvert, wing wall, foundation, deformation joints, etc. [0004] The number of holes in the culvert supports the layout of any hole culvert; the layout of the culvert supports oblique front and oblique construction except ...
