What model of groove steel sheet pile to choose for maintenance

Steel sheet piles with grid structure are divided into straight web steel sheet piles and shallow arc steel sheet piles. The grid structure can be a grid with a connecting arc or a partition type grid with a common straight partition. The grid is connected to the supporting arc by 30 ° Y piles or 90 ° T piles (hereinafter referred to as irregular piles). The 30 ° Y pile connection leaves a large space in the grid and reduces the circumferential tension in the grid. The partition type grid structure is connected by 120 ° Y piles, and the grid structure usually has 4 irregular piles. Irregular piles are made of steel sheet piles connected by welding, riveting, or high-strength bolts.
Before installing the lattice structure, check the straightness, lock shape, steel sheet pile shape, and laminated cracks of the steel sheet piles. If this inspection work is not done carefully, the pile will not be able to be inserted during pile driving, or the pile will be driven out of the lock during pile driving.
Therefore, a lock mouth of the same shape with a length of 2 meters is used to check the straightness of the steel sheet pile through the lock mouth of each steel sheet pile, and steel sheet piles with local kinks, excessive bending or warping along the lock mouth of the steel sheet pile are scrapped. Each steel sheet pile lock must be clean and free of debris, and the iron sand and paint adhered during sandblasting, rust removal, and protective paint spraying must be removed thoroughly.
Some users have better satisfaction when using steel sheet piles, but there are also some users who do not have better satisfaction during use. So, what are the reasons why users do not have better satisfaction when using this type of pile? Firstly, there are issues with the company's equipment in terms of service. Generally, users also provide services through leasing companies. However, some companies have better equipment imports, while others are inferior, resulting in a decrease in service quality.
Another issue is that the company did not consider the convenience of users in its services. When users use steel sheet piles, they not only hope to satisfy themselves in terms of quality, but also hope to have better convenience in their services. Therefore, users are eager to have better installation teams and vehicles, which naturally leads to better service convenience. On the contrary, companies without such service capabilities will find it difficult for users to be satisfied with the quality of this service.
Of course, there are differences in specifications and types when using steel sheet piles, so when users use this service, they also need to have better comprehensiveness in service. However, this is also a matter of strength. If a company does not have comprehensive strength, it is difficult for users to have better satisfaction when using the service.
So, whether there is comprehensive service in the entire steel sheet pile service is also an aspect of user satisfaction. Finally, it should be mentioned whether there is corresponding construction quality in the service. Generally, users also use steel sheet pile products together with their construction workers. If the company does not have a better construction team, users will find it difficult to be satisfied with the service quality.
Check the size and connection of each irregular pile. When the irregular pile is made by welding, the welding quality should be carefully checked to prevent the strength failure of the grid structure at the welding of the irregular pile after backfilling with filling material.
Dig out pebbles, sediments, fiber deposits that hinder the construction of grid piles, as well as silt or other unfavorable soil layers that affect the bearing capacity and stability of the grid structure, and backfill with medium coarse sand that is easy to sink.
In the implementation of steel sheet pile lattice structure technology, the following types of equipment are mainly applied:
Grid lifting equipment
The onshore assembly grid scheme requires the use of a lifting device to lift each grid pile along with the steel fence to the installation site. Before inserting steel sheet piles, the length scale mark of each pile should be marked at the height above the water surface for observation during pile sinking. There is no problem using a single point suspension for the 21m long straight composite pile. The use of a single point crane for 21~26m straight composite piles requires careful operation to prevent steel sheet piles from exceeding their yield limit.
The auxiliary arc guide frame is supported by the installed grid pile. The arc guide frame should consider the possible deviation of the four irregular piles of two grids, leaving a space of 30-40cm in the longitudinal direction of the grid.
Steel fence is used to accurately install steel sheet piles in grid structures. What is the longest length of Larson Steel Sheet Pile 2? The outer diameter of the steel fence should be 50cm smaller than the inner diameter of the grid to provide sufficient swing and rotation space for the insertion of the steel sheet pile, as well as space for the vibration hammer clamp to pass through. At the same time, it should also avoid collision with the grid pile when the steel fence is lifted out after the installation of the grid.
Land assembly grid equipment and lifting installation equipment.
