Reinforced culvert

Abstract

The invention discloses a reinforced culvert. The reinforced culvert comprises a culvert top and side walls. A prestress top plate which is composed of a symmetrically fastened double-layer corrugated steel is arranged at the bottom of the culvert top, single-layer corrugated steels are arranged on the inner sides of left and right side walls, the top plate is installed on the single-layer corrugated steels of the side walls, reinforcing steel bars are arranged in a cavity cylinder formed by the double-layer corrugated steel, the cavity cylinder is filled with concrete, and simultaneously, concrete is filled between the culvert top and the prestress top plate as well as between left and right side walls and the single-layer corrugated steels. The reinforced culvert has the advantages that a corrugated steel rigid support is added on the basis of the original culvert structure, and further expansion of cracks is prevented, so that the internal force and deformation of the original culvert structure are reduced greatly, simultaneously, the original structure is fully utilized, and shared force bearing of new and old structures is guaranteed with the using function of the original culvert unchanged.

Description

technical field [0001] The invention relates to a culvert, in particular to a reinforced culvert. Background technique [0002] In recent years, with the construction and development of infrastructure, more and more new roads have been built. Among them, mountainous roads often pass through the complex terrain of high mountains and ravines, and the phenomenon of high filling and deep excavation of the roadbed is inevitable, so the phenomenon of high filling of culverts is inevitable. Box culverts and slab culverts in high-fill areas have a large top cover soil, and it is difficult for designers to fully understand the geological conditions of the culvert base when designing culverts. If construction personnel do not strictly follow reasonable construction methods during construction The operation will cause damage to the culvert during the construction process or early use, such as bending and tensile cracks under load. A culvert ranges from tens of thousands of yuan to mi...

AI Technical Summary

Problems solved by technology

Traditional culvert reinforcement methods include embedded box structure method, enlarging cross-section method, joist pulling column method, etc. Among them, the embedded box structure method is to add a reinforced concrete box support structure on the basis of the original structure of the culvert; The large section method is to pour members of the same material inside the original culvert to increase the bearing capacity of the culvert; the joist and column method is a comprehensive technical means to remove the substructure without dismantling the superstructure; these reinforcement methods need to be used during construction. The turnover materials removed from the site are inconvenient for construction and the construction period is long. When the reinforcement components do not reach the strength, the upper part of the culvert cannot be constructed, which seriously affects the construction period.
