sheet pile bending locking structure of steel sheet pile and the sides of the.

Steel sheet pile as a building foundation construction efficient building material, can be divided into two kinds of hot rolling and cold bending.

Cold-formed steel sheet pile (Cold formed steel sheet pile), the thinner plate cold bending forming machine, with continuous rolling. The lower production cost, fixed length of flexible control, according to the actual engineering, the most economical and reasonable selection section, to realize the optimization of Engineering design.

In the actual production of cold-formed steel sheet pile locking joint shape is difficult to control, joint locking is not strict, unable to stop; restricted capacity of cold processing equipment, only the production of steel strength level low, the thickness is thin products; and bending stress generated in the process of pile body is large, easy to produce in the tear, with great processing, the limitations of use, mostly as the supplementary application materials. Thus the current hot rolled steel sheet piles into the mainstream of steel sheet pile product development.

Hot rolled steel sheet piles (Hot rolled steel sheet pile) by continuous casting and rolling process, the cogging mill and rail mill or universal mill through high temperature rolling forming, has the advantages of size specification, stable performance, reasonable section, high quality, good sealing property, strong durability etc.. The thermal processing of steel sheet pile monolithic maximum width can reach about 900mm monolithic, section modulus can reach 4000cm3. From the cross section shape, hot rolled steel sheet pile is divided into U type, Z type, H type, AS type and linear type, as shown in fig.. Because Z type, H type, AS type steel sheet pile production, processing and installation is complex, and the price is U higher than about 1/3, mainly in Europe and the United States used throughout the Asia Pacific region, including China, most of the use of U type steel sheet pile.

U type steel sheet pile code named: SP-U (SP sheet pile), Belval U (BU) Arbed U (AU) - two. (1) BU steel sheet pile more commonly used width is 600mm; the elastic bending moment values can be from 600cm3/m to 3300cm3/m; repeated use rate can reach 30; very thick, related project for high salinity, strong durability. (2) AU steel sheet pile width is 750mm, the elastic bending moment from 1400cm3/m to 2600cm3/m; and BU steel sheet pile compared, AU steel sheet pile thinner, lighter but stronger; the other angle is big, easy to pull the sheet from the soil.
