What Are The Preparation Procedures For Steel Sheet Pile Construction?

1. Prepare

(1) Construction preparations: Before the steel sheet pile is driven in, the groove at the tip of the pile should be closed to prevent mud from entering, and the lock should be coated with butter or other grease. For steel sheet piles that have been in disrepair for a long time, the locks are deformed, and the corrosion is serious, they should be repaired and corrected. The bent and deformed piles can be corrected by pressing with an oil hydraulic jack or by fire.

(2) Division of piling water section.

(3) During the piling process. In order to ensure the verticality of the steel sheet pile. Controlled in both directions with two theodolites.

(4) The position and direction of the first and second steel sheet piles to be driven should be accurate so as to serve as a guiding model. Therefore, it should be measured every 1m driven in, and immediately after driving to the predetermined depth, use steel bars or steel plates and purlin The bracket is welded for temporary fixation.

2. Equipment preparation

1. Impact piling machinery: free fall hammer, steam hammer, air hammer, hydraulic hammer, diesel hammer, etc.

2. Vibration piling machinery: This kind of machinery can be used for both piling and pile pulling, and the most commonly used one is the vibrating pile pulling hammer.

3. Vibration and impact piling machinery: This kind of machinery is equipped with an impact mechanism between the body of the vibratory piling machine and the fixture. When the vibrating machine vibrates up and down, it generates impact force, which greatly improves construction efficiency.

4. Static pile pressing machine: press the sheet pile into the pile by static force.
