Steel Sheet pile Description 

The steel sheet pile is a kind of steel structure with a linkage device on the edge, and this linkage device can be freely combined to form a continuous and compact steel structure with a retaining wall or a water retaining wall.

definition

The steel sheet pile is a type of steel with a lock. Its cross-sections are straight, trough and Z-shaped. There are various sizes and interlocking forms. The common ones are Larsonian, Lakwanaian and so on. Its advantages are: high strength, easy to penetrate hard soil; can be constructed in deep water, if necessary, add diagonal support to become a cage. It has good waterproof performance; it can be formed into cofferdams of various shapes as required and can be reused many times. Therefore, it has a wide range of uses.

classification

Steel sheet pile products are classified into cold-formed thin-walled steel sheet piles and hot-rolled steel sheet piles according to the production process.
(1) There are two types of cold-formed steel sheet piles: non-bite type cold-formed steel sheet piles (also called channel plates) and bite type cold-formed steel sheet piles (divided into L-shaped, S-shaped, U-shaped, and Z-shaped) . Production process: Use thinner plates (commonly used thickness 8mm ~ 14mm) to be continuously rolled and formed in the cold bending unit. Advantages: less investment in the production line, lower production cost, flexible control of product size. Disadvantages: the thickness of each part of the pile body is the same, the section size cannot be optimized, which leads to an increase in steel consumption, the shape of the lock part is difficult to control, the joint is not tightly buckled, and the water cannot be stopped, and the pile body is easy to tear during use.
(2) Hot-rolled steel sheet piles Hot-rolled steel sheet piles in the world mainly include U-shaped, Z-shaped, AS-shaped, H-shaped and dozens of specifications. The production, processing and installation processes of Z-type and AS-type steel sheet piles are relatively complicated, and are mainly used in Europe and America; U-type steel sheet piles are mainly used in China. Production process: It is formed by high temperature rolling by a section steel rolling mill. Advantages: standard size, superior performance, reasonable cross-section, high quality, and tight water barrier for the lock bite. Disadvantages: technical difficulty is relatively high, production cost is relatively high, specification series are not flexible.
In engineering construction, the application range of cold-formed steel sheet piles is relatively narrow, and most of them are used as supplementary materials for applications. Hot-rolled steel sheet piles have always been the leading product for engineering applications. Based on the many advantages of steel sheet piles in construction operations, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the National Standardization Management Committee issued the national standard for "Hot Rolled U-shaped Steel Sheet Pile" on May 14, 2007, and on December 1, 2007 Formally implemented. At the end of the 20th century, Maanshan Iron & Steel Co., Ltd. produced more than 5,000 tons of U-shaped steel sheet piles with a width of 400mm with the introduction of the universal rolling mill production line from abroad. The U-shaped steel sheet piles were successfully used in the cofferdam of Nenjiang Bridge and the 300,000 tons of Jingjiang New Century Shipyard. Ton shipyard and Bangladesh flood control projects. However, due to the low production efficiency, poor economic efficiency, low domestic demand and insufficient technical experience during the trial production period, continuous production was not possible. According to statistics, the annual consumption of steel sheet piles in my country remains at about 30,000 tons, accounting for only 1% of the world’s total, and it is limited to permanent projects such as the construction of some ports, wharves, and shipyards, as well as the construction of bridges, cofferdams, and foundation pit support Temporary works.
The cold-formed steel sheet pile is continuously rolled and formed by the cold-formed unit, and the side lock can be continuously overlapped to form a steel structure of the sheet pile wall. The cold-formed steel sheet pile is made of thinner plates (commonly used thickness is 8mm-14mm) and processed by cold-formed forming units. The production cost is lower and the price is cheap, and the fixed-length control is more flexible. However, due to the simple processing method, the thickness of each part of the pile body is the same, the cross-sectional size cannot be optimized, which leads to an increase in steel consumption; the shape of the lock part is difficult to control, the joint is not tightly buckled, and the water cannot be stopped; limited by the capacity of cold bending processing equipment, It can produce low-strength steel products with relatively thin thickness; and the stress generated in the cold bending process is relatively large, and the pile body is easy to tear during use, and the application has greater limitations. In engineering construction, the application scope of cold-formed steel sheet piles is relatively narrow, and most of them are only used as supplementary materials. The characteristics of cold-formed steel sheet piles: According to the actual situation of the project, the most economical and reasonable section can be selected to achieve the optimization of engineering design. Compared with the hot-rolled steel sheet piles of the same performance, the material can be saved by 10-15%, which greatly reduces the construction cost.

Shape category

U-shaped steel sheet pile
basic introduction
1. The section structure design of WR series steel sheet piles is reasonable, and the forming technology is advanced, so that the ratio of section modulus to weight of steel sheet piles is continuously improved, so that it can obtain good economic benefits in application, and broaden cold-formed steel sheet piles. Application areas.
2. The specifications and models of WRU steel sheet piles are abundant.
3. Designed and produced according to European standards, the structure is symmetrical to facilitate repeated use, and is equivalent to hot rolling in repeated use, and has a certain angle of rotation, which is convenient for correcting construction deviation;
4. The use of high-strength steel and advanced production equipment ensure the performance of cold-formed steel sheet piles;
5. The length can be specially customized according to customer requirements, which brings convenience to the construction and reduces the cost.
6. Due to the convenient production, it can be pre-ordered before leaving the factory when it is used with combined piles.
7. The production design and production cycle are short, and the performance of steel sheet piles can be determined according to customer requirements.

advantage:
1) The U-shaped steel sheet pile has various specifications and models.
2) Designed and produced according to European standards, the structure is symmetrical, which is conducive to repeated use, and is equivalent to hot rolling in repeated use.
3) The length can be specially customized according to customer requirements, which brings convenience to the construction and reduces the cost.
4) Due to the convenience of production, it can be pre-ordered before leaving the factory when it is used with combined piles.
