Larsen steel sheet pile models are generally: 6 meters, 9 meters, 12 meters, 15 meters, 18 meters and so on.

When choosing sheet piles, pay attention to the following points:

1. The location of the steel sheet piles should meet the design requirements and facilitate the earthwork construction of the trench foundation, that is, leave room for formwork and formwork removal outside the protruding edge of the foundation.

2. The shape of the support plane of the trench steel sheet piles in the foundation pit should be as straight and neat as possible to avoid irregular corners, so as to facilitate the use and support of standard steel sheet piles. The dimensions of each peripheral should be as many as possible to install the module of the composite board.

3. During the entire foundation construction period, during the construction operations such as digging, lifting, tying steel bars, pouring concrete, etc., it is strictly forbidden to collide with the support, prohibit the arbitrary removal of the support, prohibit any arbitrary cutting on the support, and do not place heavy objects on the support.
