Corrugated Steel Is Used Very Much On Construction Sites



Corrugated steel is a rugged economic section of steel, with convenient construction, light weight, corrosion resistance, terrain pressure, low price advantages. The United States, Canada, Japan, Korea and other countries of road engineering has been widely used corrugated steel, Corrugated Steel and developed a design, manufacturing, construction and installation manuals and specifications.

Corrugated steel is now used in construction sites is very large, it is a structural defect of concrete replacement materials. Corrugated steel has many advantages, such as: very durable, shorten the construction time, green environmental protection and so on. Apply to a variety of environment, currently in rural areas, urban buildings, oceans and so on are applied corrugated steel. And the service life of corrugated steel is very long, which greatly saves the maintenance period of the building, Corrugated Steel which saves the capital and the environment.

With the continuous progress of steel structure application technology in China, corrugated steel culvert has been used more and more in highway construction, including Cross River Bridge, tunnel, cold area windproof channel, near the road to prevent talc hole, open coal mine coal conveying channel, roadway and other fields, at present, has accumulated a relatively mature corrugated culvert design methods and construction experience. In recent years, Corrugated Steel Nanjing Beltway Expressway, Shanghai A15 Expressway, Jiangsu-Anhui Trans-Boundary Highway, Jurong Expressway, such as a number of corrugated steel highway construction has been completed. In addition, the corrugated steel culvert has been successfully applied to the construction of the Weihe River Bridge, which has also been explored in the application of corrugated steel to large-scale bridges with load-bearing requirements and adapting to overload deformation.

The wide application of corrugated steel has benefited from its excellent performance. The corrugated design makes it have excellent mechanical characteristics, vertical, axial, and circumferential distribution can be distributed at the same time because of compression strain caused by pressure, flexible, Corrugated Steel high-strength bellows and backfill material interaction can form an effective support to achieve more high pressure bearing force. Especially suitable for ground deformation, frost heave and settlement of frozen soil area, cold area and soft soil area, can effectively avoid the deformation of reinforced concrete bridge and culvert, Corrugated Steel cracking and other problems arise.

Characteristics of corrugated steel structure

Corrugated steel is a certain size and thickness of steel plate by a specific mold roll pressure into corrugated shape of structural plate, due to the existence of waveform, the steel corrugated steel to increase the bending inertia moment, so that it has a high bearing capacity and stability.

Corrugated Steel Advantages:

Short construction period

Corrugated steel pipe corridor for the whole corrugated steel pipe (pipe diameter <3m) or assembled corrugated steel plate, its material in the factory processing production, on-site assembling, construction speed, compared to traditional concrete structure cast-in-place pipe corridor construction cycle can save more than 30%.

II. Price Advantage

Corrugated steel structure is a thin steel shell with simple structure and low engineering cost. Take 4x3.5m reinforced Concrete Pipe corridor For example, the cost of its civil construction is about 80 million yuan per kilometer, and the use of φ4.5m corrugated steel pipe replacement, Corrugated Steel its civil construction cost of about $MODELTYPE million per kilometer, its function can meet the demand. It has obvious advantage over traditional concrete structure in cost.

III. Strong adaptability

When the reinforced concrete structure has uneven settlement deformation, it is easy to produce cracks and other diseases, and the corrugated steel structure has the ability to adapt to the Foundation and foundation deformation, Corrugated Steel so as to avoid the structural damage caused by uneven settlement of the foundation.

IV. Standard Environmental protection

The corrugated steel structure uses the factory standardized design, the production, the structure is simple, the quality is easy to control. Corrugated steel structure reduces the amount of natural materials such as cement, gravel, sand and so on, protecting environment and low carbon environment.
