Feature

1. The section width is large, and the pile sinking effect is remarkable.

2. Large section modulus.

3. The higher moment of inertia increases the rigidity of the steel sheet pile wall and reduces structural deformation.

4. Excellent anti-corrosion effect.

Advantage

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 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 excellent.

Use

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

Device Selection

The Z type steel sheet pile is sunk by a vibratory pile driver, so 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 easily damaged, 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, reduce the resistance around the Z type steel sheet pile, and facilitate the penetration of the sheet pile.

Construction process

The Z type steel sheet piles are driven by the vibratory piling method, and the piles are pulled out by a 50-ton crawler crane with a vibratory hammer. The construction steps of Z type steel sheet piles are in order: set guide pile frame→clean up Z type steel sheet pile→insert and drive Z type steel sheet pile→set inner support→plug leak→suction mud→harden base→construction of cap and pier body→remove Z type steel sheet pile.

Insert and drive Z type steel sheet piles. Fix the temporary guide frame on the drilling platform, and place the pile hammer under stable conditions. Insert the stakes until they are all closed, and then drive to the elevation in sections and in stages. The sequence of pile insertion starts from the middle of the upstream and is symmetrically inserted on both sides to the downstream. The single sheet pile construction method combined with the screen method is used for piling. First, drive the sheet piles into the soil one by one. In order to prevent tilting, after a pile is driven in, it is welded firmly with the previous one, which prevents tilting and prevents the piles driven later from being brought into the soil. 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 order, so as to prevent the inclination of the sheet piles and turn.

plugging. After the Z type steel sheet pile is inserted and driven in place, a circle of colored cloth can be wrapped around it, and the lower end of the cloth is bound with a steel pipe to sink into the river bed and pressed with a sandbag. When the weir sucks mud, the outer water pressure can push the colored cloth It is close to the sheet pile to play a certain role in waterproofing, and cotton sand is used to plug the leaking place where the lock on the side of the sheet pile is not tight, and the blocking effect is obvious. For deeper leaks, coal slag, etc. can be sent to the leaking place to plug the leak.
