The corrugated culvert equipment is a flexible structure, which has excellent characteristics of lateral compensation for displacement in the structure, can fully exert the characteristics of strong tensile strength and superior deformation function of steel, and has a large ability to resist deformation and settlement, which can avoid the superstructure For questions such as material damage, it is usually selected for factory manufacturing.The culverts and supporting accessories are processed by hot dip galvanizing before leaving the factory.Each manufacturing process has strict quality inspection checks.After being transported to the construction site, paint them on the construction site. Asphalt, to further enhance the maintenance and anti-corrosion of its appearance, in order to strengthen its planned service life, in the later operation process, it can also be reinforced and maintained by adding an asphalt coating on the inner wall of the pipe according to detailed conditions, which is more durable than traditional masonry culverts. The advantages of low maintenance cost and low reconstruction rate.
The corrugated pipe culvert equipment is a flexible structure. After it is built, it forms a combined structure with the surrounding soil and is under common stress. The wedge of the corrugated pipe culvert and the backfill soil on both sides are critical. Some of the large stones directly act on the pipe body, which will show some large deformation or some protrusions. There are hidden dangers to safety and serious quality accidents may occur. Strict control is required. The steel bellows is round or arched along the diameter direction, and there are several small corrugated arches in the longitudinal direction, forming a double-curved arch vertically and horizontally, which has similar properties to the double-curved arch bridge in China. It is known from mechanics that the arch type is under vertical load , The support will not only produce vertical reaction force, but also produce a degree of thrust. Due to the existence of the degree of thrust, the bending distance of the arch will be much smaller than that of the beam or bridge of the same span, so that the entire arch mainly receives pressure. Bellows There are several support points around the culvert, which form a stable bearing capacity.
The soil body around the corrugated culvert pipe equipment forms a support under load, and the soil body and the corrugated pipe form a combined structure, so that the corrugated pipe can accept a great bearing capacity. Metal materials and metal corrugated culverts mainly discuss the relationship between the composition of metals and alloys, the heat treatment process experienced and their internal organization and performance, and how to improve the organization and performance of metals and alloys. As long as these knowledge are controlled, they can be rationally selected. Metal corrugated culvert can fully utilize its potential, extend the service life of corrugated culvert and reduce the cost. In addition, in order to correctly formulate casting, forging, welding, heat treatment and cutting processing of metal corrugated culverts, and improve the quality and output of products, it is also necessary to learn the knowledge of metal corrugated culverts.
The application scope of corrugated culvert pipe equipment is universal, and it can be applied to common ground, soft ground, collapsible loess ground, and rock foundation. In the case of severe acid and alkali corrosion, the anticorrosion plan can be adjusted, and the compliance is universal. Steel corrugated culvert is a culvert tube made of corrugated steel plate and rolled or assembled. It is used in highway and railway culverts and other projects. It can also be made into cross-line passages, tunnels and roadway roofs in semicircular or other curved ways. Protect. The steel corrugated culvert has a wave shape along the length of the pipe, and it has a strong ability to conform to the longitudinal deformation. It can prevent the formation of damage due to uneven settlement of the foundation. Without increasing the amount of data, the radial load of the pipe can be improved several times. Because of its superior performance and compliance, it can be widely used abroad for highway engineering, railway engineering, mine tunnels, tunnel engineering, municipal engineering and military passages
