Site pile driver manufacturer: Steel sheet pile is a type of steel with a lock, and its cross section has straight plate, groove, Z-shaped interlocking forms. The common ones are Larsonian, Lakwanaian and so on. Its advantages are high strength and easy to penetrate into hard soil; it can be built in deep water and can be tilted to form a cage if necessary. The water-proof performance is good, and the cofferdams formed into various shapes can be used repeatedly according to the needs, so it is widely used.

Setting steps of steel sheet pile machine:

(1) Selection of the driving method of the steel sheet pile machine

The method of entering individually is to start from the corner of the board wall and hit one block at a time (or two blocks as a group) until the end of the project. Its advantage is that the construction is simple and quick, and no other auxiliary support is needed. The disadvantage is that it is easy to tilt the sheet pile to one side, which is wrong. It is difficult to correct cumulative differences. Therefore, the single driving method is only suitable for sheet pile walls with low requirements and short sheet pile length (such as less than 10m).

(2) Screen driving method of steel sheet pile machine

When 10-20 steel sheet piles are inserted into the guide frame in a screen-like row, and then driven in batches, the steel sheet piles at both ends of the screen wall will be driven into the design elevation or a certain depth to become positioning steel sheet piles. Drive in l/3 and 1/2 sheet piles step by step in the middle. The advantage of the screen driving method is that it can reduce the tilt. Accumulation of tilt error, avoid excessive tilt, easy to achieve closure, and can ensure the quality of sheet pile wall construction. The disadvantage is that the self-standing height of the plug-in pile is relatively large, so attention should be paid to the stability of the plug-in pile and construction safety.

(3) Construction

When the steel sheet pile machine is driving, the driving position and direction of one or two steel sheet piles to be driven at the beginning should be accurate and can be used as a template guide. For movement, it should generally be measured-times per 1 meter. Special-shaped sheet piles can be used for corner construction of sheet piles. Fitting method, overlapping method, axis adjustment method, etc. To ensure safe construction, attention should be paid to observe and protect the scope of work. Important pipes and high-voltage cables in the enclosure.

(4) Pull out the steel sheet pile by the steel sheet pile machine

When the foundation pit is backfilled, the steel sheet pile should be pulled out and reused after completion. Before pulling out, study the pulling out of the steel sheet pile. Demolition sequence, demolition time and pile hole treatment method. Pull out the steel sheet pile, in order to overcome the resistance of the steel sheet pile, according to the use.

Site pile driver manufacturers: pile pulling machinery, pile pulling methods include static pile pulling, vibration pile pulling and impact pile pulling. Pay attention to observation and balance when disassembling. Protect important pipelines and high-voltage cables within the scope of work.
