Larsen steel sheet pile instability will bring the impact of the ground

Views:2    

Larsen steel sheet pile construction If the Larsen steel sheet pile is not deep enough, then Larsen steel sheet pile support stiffness is not enough, it will lead to groundwater or groundwater into the trench. A vicious cycle will lead to Larsen steel sheet pile behind the deformation of the soil is too large, a direct result of Larsen steel sheet pile instability. Here we come to analyze the impact of the Larsen steel sheet pile will bring the impact of the ground?


1、small deformation of the ground settlement value ≤ 50mm, it will affect the range of 1-1.5 times the depth of the trench;

2、moderate deformation of the ground subsidence value of 50-100mm, it will affect the scope of more than 1.5 times the depth of excavation pit;

3、large deformation of the ground settlement value ≥ 100mm, it will affect the scope of more than 2.5 times the depth of excavation pit.


So the use of Larsen steel sheet pile to do the retaining works, the pile into the ground when the ground should pay attention to not let the soil into the pile empty, the place of the lock, generally for the convenience of use, usually at the lock Grease to facilitate construction operations. In the process of piling, we must keep the Larsen steel sheet pile vertical, usually with the theodolite to detect, piling, we must keep the front of the two Larsen steel sheet pile in the direction to be consistent in order to facilitate the later Larsen steel Pile pile in front of the pile.

    

Larsen steel sheet pile is a type of steel with a lock, in recent years, with its high strength, good water barrier, simple construction, can shorten the construction period, a large reduction in the amount of soil and the use of concrete and anti- And other advantages, widely used in the terminal, embankment protection shore, retaining walls, docks, drying, bridge cofferdam and other projects. In recent years, with the rapid development of China's economy, Larsen steel sheet pile with its high strength and light weight, good water, durable, high construction efficiency, less land itself inherent unique performance, is applied to a variety of projects in.
