The steel sheet pile is a kind of steel structure with linkages on the edge, and the linkages can be freely combined to form a continuous and compact retaining wall or water retaining wall.
Steel sheet pile is a kind of section steel with lock. Its section has straight plate shape, groove shape and Z shape, etc., and there are various sizes and interlocking forms. The common ones are Larson type, Lackawanna type and so on. Its advantages are: high strength, easy to drive into hard soil layer; it can be constructed in deep water, and if necessary, it can be added with oblique support to form a cage. Good waterproof performance; cofferdams of various shapes can be formed according to needs, and can be reused many times, so it has a wide range of uses.
Z type steel sheet pile
The locks are symmetrically distributed on both sides of the neutral axis, and the web is continuous, which greatly improves the section modulus and bending stiffness, and ensures that the mechanical properties of the section can be fully utilized. Because of its unique cross-sectional shape and reliable Larssen lock.
Advantages of Z-shaped steel sheet piles:
1. Flexible design, relatively high section modulus and mass ratio;
2. Higher moment of inertia, which increases the stiffness of the sheet pile wall and reduces displacement deformation;
3. The width is large, which effectively saves the time for hoisting and piling;
4. The increased section width reduces the number of shrinkages of the sheet pile wall and directly improves its water-tight performance;
5. The thickening treatment is carried out on the severely corroded parts, and the corrosion resistance is more excellent.
Steel sheet piles have a wide range of applications, as listed below;
(1) River bank protection and flood control. Steel sheet piles are often used in river revetment, ship locks, ship lock construction, flood control, etc. The advantage is that they are suitable for water conservancy projects and have a long service life.
(2) Ports and terminals. Steel sheet piles are a more suitable material for wharf construction. It meets the requirements of rapid and economical wharf construction, and has good mechanical properties, and can withstand large vertical loads and lateral bending moments.
(3) Water collection stations. Previously used as temporary support for pumping stations, sheet piles can also be used in structures, significantly reducing construction time and costs. The pump station is usually a rectangular structure, but judging from the existing open structure, the circular shape will be the future development trend.
(4) Piers. Sheet piles are economical when the pile foundation is load bearing or when speed of construction is required. It can function as a foundation and a pier at the same time, or it can work in one direction, taking up little time and space.
(5) Road widening retaining wall. The key to road widening lies in the amount of land acquisition and construction speed, especially in the case of borrowing other lanes, steel sheet piles can meet the above requirements without excavating and clearing the soil.
(6) CELLAR. Because it takes up so little space, sheet piles are ideal for building basement walls. This feature of steel sheet piles is utilized both temporarily and structurally, which can greatly reduce costs. In addition, sheet piles can also withstand vertical loads from the superstructure.

(7) Underground garage. Steel sheet piles have become a more effective material for building underground garages. They can be driven firmly into the ground, and the relatively small thickness of the sheet piles themselves means that space and cost in car parks can be maximized.
(8) Insulation arrangement. The sealed steel sheet pile is a material for isolating sundries, and some special sealants can be used to meet the anti-seepage requirements in specific cases. Guangxi steel sheet pile
(9) Bearing foundation. As an ideal load-bearing infrastructure, sheet piles can be combined with special corner piles to form closed structures with small diameters. As sheet piles are increasingly used as support systems for road signs, the concept is also being used for foundation piles for bridges.
(10) Temporary works. For projects requiring support and excavation, in temporary projects, the basic performance of high strength and simple construction of steel sheet piles is brought into play. At the same time, the steel sheet pile can be pulled out and reused after use, which is a design choice.
Zhengde Hot-rolled steel sheet piles mainly have three shapes: U-shaped steel sheet piles, Z-shaped steel sheet piles and linear steel sheet piles, as shown in Figure 1. Among them, Z-shaped steel sheet piles and linear steel sheet piles are relatively complicated in production, processing and installation. The price is 1/3 higher than that of U-shaped steel sheet piles.
Steel sheet pile construction adopts vibration pile sinking construction, erecting single-layer double-sided guide frames, and screen-type driving method to drive steel sheet piles.

Our Advantages
Excellent characteristics
As a reusable green and environment-friendly foundation structure material, hot-rolled U-shaped steel sheet piles are highly efficient, durable, simple, lightweight, and have an excellent cross-sectional shape that is sealed and anti-seepage. And unique advantages such as safety and environmental protection.Compared with other structures, it has a light structure, strong bearing capacity, and good earthquake resistance; strong water insulation, which can make the structure quickly stop water or plug leaks, impervious to penetration and easy to construct.
Major application
The first phase project of Shanghai Changxing Island Shipbuilding Base, Tangshan Caofeidian Coal Wharf and other major projects, the amount of one-time steel sheet piles for these projects has reached 10,000 tons. In addition, in the application of foundation pit enclosure, water retaining cofferdam, wharf construction, etc., such as the second phase project of Pudong International Airport, Shanghai World Expo Project, and the temporary enclosure of steel sheet piles for Hangzhou Bay Bridge are also relatively large.
Attention to detailSteel sheet piles are inspected for appearance surface defects, length, width, thickness, height, end square ratio, straightness and lock shape, and channel steel piles are inspected for appearance surface defects, length, width, thickness, height, end angle , straightness and other inspections, cut off the welded parts on the pile that affect the pile driving (there are cut holes and section defects should be reinforced).
Full range
Cold-formed steel sheet piles and hot-rolled steel sheet piles can be produced in U-shape, Z-shape, and W-shape. The manufacturing process is different. The wall thickness of cold-formed steel sheet piles is the same, and the thickness of hot-rolled steel sheet piles is different in different parts. do thick.
The length of hot-rolled steel sheet piles is generally limited, mainly 9 meters, 12 meters, 15 meters, 18 meters, 400 wide, and 600 wide. The water stop effect is generally better than that of cold bending, and the market stock is large.
