Short installation and construction period
Corrugated metal pipe culvert is one of the new technologies promoted in highway engineering projects in recent years, it is 2.0-8.0mm high-strength thin steel plate pressed into corrugated steel, according to different pipe diameter rolled into a pipe section to replace the reinforced concrete culvert. Corrugated pipe culvert installation period is only 3-20 days, compared with concrete cover culvert, box culvert, saving more than 1 month, wide range of application, social and economic benefits.
Strong resistance to deformation and settlement
Highway constructed in coal mining hollow area, due to underground mining can cause the ground to different degrees of decline, resulting in uneven settlement, the general cement composition of different degrees of damage. Steel corrugated steel pipes culvert is a flexible structure, corrugated steel pipe in the structure of the lateral compensation of the displacement of the excellent characteristics, can give full play to the strong tensile properties of steel, deformation of the characteristics of superior performance, with greater resistance to deformation and settlement capacity. Especially suitable for soft soil, swelling land, wet loess foundation bearing capacity of low places and earthquake-prone places.
High corrosion resistance
Corrugated pipe culvert has higher corrosion resistance than traditional reinforced concrete pipe culvert. The pipe joints are hot dip galvanized and the ports are sprayed with asphalt for anti-corrosion treatment. It solves the problem of damage to concrete structure in wet and cold areas, and the effective working life is longer than that of traditional culverts.
Environmental protection and low carbon
Corrugated metal pipe culvert reduces or simply abandon the use of conventional building materials, such as cement, medium and coarse sand, gravel, wood. Corrugated metal pipe culvert is made of green and non-polluting materials, which is conducive to the protection of the environment and the reduction of carbon emissions.
Fast opening time and easy maintenance
Corrugated metal pipe culvert from excavation to backfill can be completed in one day, compared with the traditional reinforced concrete structure, greatly saving the construction time, so that the duration of the consumption of the cost is also significantly reduced. Corrugated metal pipe culvert later maintenance is convenient, in a considerable part of the environment and even without maintenance, so that the maintenance cost is greatly reduced, the economic benefits are outstanding.
Summarize
Corrugated metal pipe culvert in highway engineering has a short installation and construction period, fast opening time, easy maintenance, low carbon and environmental protection, high corrosion resistance, high resistance to deformation and corrosion resistance. In the construction of highway projects, the use of corrugated pipe culvert can also make the road transportation efficiency is not affected, but also to strengthen its application in the maintenance project, the social benefits are significant.
