Z-shaped steel sheet piles, building materials, and Z-shaped steel sheet pile locks are symmetrically distributed on both sides of the neutral axis. Coupled with the continuity of the web, the section modulus of the steel sheet pile has been improved to a large extent. Ensure that the mechanical properties of the section are fully utilized.

Feature
1. The cross-section width is large, and the pile sinking effect is obvious.
2. The section modulus is large.
3. The higher moment of inertia enhances the rigidity of the steel sheet pile wall and reduces structural deformation.
4. Excellent anti-corrosion effect.

Liansen Brand Z-shaped steel sheet piles Advantage

1. Economical
Z-shaped steel sheet piles can construct continuous walls with large cross-sectional shapes through the design of the locks at both ends. Compared with the cross-sections of general steel sheet piles such as U-shaped steel sheet piles, it is a product with lighter weight, higher cross-section performance, and higher efficiency. It is for this reason that the cost of materials can be greatly reduced when the cross-sectional properties are the same.
2. Shorten the construction period 　　
The Z-shaped steel sheet pile with a larger cross-sectional shape can reduce the number of construction roots when the length of the construction is the same, so as to reduce the time for picking and driving the steel sheet pile and shorten the construction period.
3. Water stop 　　
The Z-shaped steel sheet pile with a larger cross-sectional shape can be reduced by reducing the number of construction when the length of the construction is the same, and the lock part that will cause a little water leakage will also be greatly reduced, and the amount of water leakage can be effectively suppressed. In addition, the GQNS-Z type lock has a smaller clearance than the existing cold-formed steel sheet piles, which can exert more excellent water resistance.
4. The reliability of the structure 　　
The lock position of the Z-type steel sheet pile is located outside the central axis, and will not be affected by the longitudinal shear force generated near the central axis during bending deformation, and the lock will not trip. It is a reliable product that will not reduce the interface performance due to tripping.

Applications

Z-type steel sheet piles are widely used in automobiles, railway vehicles, shelves, electrical cabinets, highway guardrails, building steel structures, containers, transmission towers, steel sheet piles, cable bridges, agricultural machinery, furniture, vegetable greenhouses, pipe supports and other fields.

Device Selection

The Z-type steel sheet pile is sinked by a vibratory pile driver, the construction speed is fast, and the pile pulling effect is better. Compared with the impact pile driver, the construction noise is small, the pile top is not easy to damage, the operation is simple, and there is no smoke generated by diesel or steam hammer construction. The principle of the vibratory pile driver is to transmit the vertical vibration generated by the machine to the pile body to reduce the resistance around the Z-shaped steel sheet pile, which is conducive to the penetration of the sheet pile.

Construction process

The Z-type steel sheet pile is driven by vibration piling method, and the pile is pulled out by a 50-ton crawler crane with a vibrating hammer. The construction steps of Z-type steel sheet piles are in order: set guide pile frame→clean up Z-type steel sheet piles→insert and drive Z-type steel sheet piles→set internal supports→plug leakage→suction mud→harden base→construction of platform and pier body→remove Z Type steel sheet pile.

Insert Z-shaped steel sheet piles. Fix the temporary guide frame on the drilling platform and install the pile hammer under stable conditions. Insert the piles until they are all closed, and then drive them to the elevation in sections and times. The sequence of pile-inserting starts from the middle of the upstream and symmetrically inserts on both sides of the pile and closes in the downstream. The single sheet pile construction method and the screen method piling are combined during pile driving. First drive the sheet piles into the soil one by one. In order to prevent tilting, after one pile is driven, weld it to the previous one to prevent tilting and avoid being carried into the soil by the piles driven later. Insert 10-20 sheet piles into the soil to a certain depth, make the pile machine hammer back and forth, and drive the piles at both ends to the required depth first, and then drive the sheet piles in the middle part in sequence to prevent the sheet piles from tilting And turning.

Plugging. After the Z-type steel sheet pile is inserted in place, a circle of colored strips can be enclosed on its outer side, and the steel pipes can be tied to the bottom of the cloth to sink into the river bed, and pressed with sand bags. Close to the sheet pile, play a certain role in waterproofing, use cotton sand to plug the leaking part of the side of the sheet pile that is not dense, and the blocking effect is obvious. The deeper leakage can sink coal ballast to the leaking place to stop the leakage.
