Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as Figure 1~3 As shown, a self-unloading steel corrugated plate arched culvert includes an arched steel corrugated plate 1 arranged along the direction of the culvert, and a concrete foundation 6 is arranged at the arch foot of the steel corrugated plate 1; 1 The upper self-unloading unit; the self-unloading unit includes a plurality of steel pipes 3 arranged along the direction of the culvert and uniformly distributed on the outside of the steel corrugated plate 1, and a steel plate 2 is arranged above the steel pipes 3; unloading effect.

[0027] A filling layer 4 is arranged between adjacent steel pipes 3 . The filling layer 4 is formed by mixing one or two of crushed stones or sand pebbles in any proportion; the steel pipe 3 is provided with cement slurry 7 . The filling layer 4 and the cement slurry 7 are injected through t...

Abstract

The invention discloses a self-unloading steel corrugated plate arch culvert. The self-unloading steel corrugated plate arch culvert comprises a steel corrugated plate of an arch structure arranged inthe culvert direction, and a concrete foundation is arranged at the arch foot position of the steel corrugated plate; the self-unloading steel corrugated plate arch culvert further comprises a self-unloading unit arranged at the upper part of the steel corrugated plate; the self-unloading unit comprises a plurality of steel pipes which are uniformly distributed on the outer side of the steel corrugated plate in the culvert direction, and a steel plate is arranged above the steel pipes; and in the culvert filling process, the steel pipes have certain deformability and can play a role in reducing the arch load of the culvert, meanwhile, gravel or sandy gravel can be duly blown and filled among the steel pipes according to the deformation condition of the culvert so as to limit further deformation of the steel pipes, and after the filling height is reached, grouting is conducted through reserved grouting holes, so that the integrity and durability of the structure are guaranteed. The culvert is complete in functions, flexible, simple, convenient, environment-friendly and efficient, greatly reduces the investment of engineering materials, accelerates the construction progress, guarantees the construction safety, shortens the construction period, and is obvious in economic benefit.

Description

technical field [0001] The invention relates to the technical field of culvert support systems, in particular to a self-unloading arched culvert with corrugated steel plates. Background technique [0002] In recent years, with the rapid improvement of my country's economic strength and comprehensive national strength, the state's investment in infrastructure construction has continued to increase. As an important part of railways and highways, culverts account for about 60% to 70% of the total bridges and culverts, and their cost accounts for about 40% of the total bridges and culverts, occupying an important position in engineering construction. At present, the supporting structure of culverts mainly adopts reinforced concrete, and its construction efficiency is low, and its economic benefits are not obvious. [0003] At the same time, my country is gradually focusing its work on developing a low-carbon economy and protecting the environment. Therefore, the research and d...
