Truss type steel aqueduct with corrugated web plates

Abstract

The invention discloses a truss type steel aqueduct with corrugated web plates. The truss type steel aqueduct with corrugated web plates comprises a steel box girder body using the corrugated web plates, and at least two truss supporting structures, wherein the steel box girder body is symmetrically arranged along the central axis, uses a groove-shaped or U-shaped cross section, and consists of the corrugated web plates and a bottom plate; the at least two truss supporting structures are symmetrically arranged along the central axis; each truss supporting structure consists of chord members, lateral bracings arranged between two truss lower chord members, web members, and cross bracings arranged between two truss web members; each corrugated web plate is positioned between the lateral bracings of the truss supporting structures; the bottom plate is supported on the cross bracings; and partition plates are arranged at the inner sides of the lateral bracings for providing lateral supportfor the corrugated web plates. An all-steel structure is used; the watertight performance is good; the structure can be assembled and constructed on site after being prefabricated in sections in a factory; the construction speed is high; and the construction quality can be easily guaranteed. Compared with a concrete structure, the steel structure has the advantages of small dead weight and higherspanning capacity, so that the steel structure is more suitable for construction of large flow cross section and large-span aqueducts.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering and building structure, and relates to a truss-type navigable steel aqueduct with corrugated webs. Background technique [0002] An aqueduct is a water delivery system consisting of bridges, tunnels or ditches for water, traffic and navigation. Aqueducts are usually erected on rivers or valleys, and are widely used in water conservancy projects and drinking water projects. In order to ensure the safety of the water delivery process, aqueducts need to meet the requirements of bearing capacity and watertightness. Traditional aqueducts usually use prestressed reinforced concrete structures. Prestressing is applied to the bottom plate and side walls to avoid tensile cracking of the concrete structure. The number of prestressed tendons is large and the layout is complicated. The on-site construction work is very cumbersome and difficult to guarantee the quality of the project. Due to the la...

AI Technical Summary

Problems solved by technology

Traditional aqueducts usually adopt prestressed reinforced concrete structures. Prestressing is applied to the bottom plate and side walls to avoid tensile cracking of the concrete structure. The number of prestressed tendons is large and the layout is complicated. The on-site construction work is very cumbersome and difficult, and the quality of the project is difficult to guarantee.

Due to the large loss of lateral prestress of the traditional bottom plate and the problem of prestress relaxation over time, this will increase the risk of cracking of the concrete tank body and make it difficult to repair after cracking
