How many types of piling are there on the site?
According to the construction process and divided into cast-in-place pile and precast pileThe resistance of the soil to the pile is overcome by the impact of the pile hammer, so that the pile sinks to a predetermined depth or reaches the bearing layer. (of course, this is to explain "piling". There are several ways to make a precast pile to a predetermined depth or a bearing layer, such as static pressure, vibration, water, etc.)
According to the pile force divided into friction pile and end bearing pile. The friction pile is a friction pile wall and the use of sediment to bear the weight of the upper building structure; end bearing pile is the pile formation hit solid ground, and the load of the upper structure of pile to solid strata.
Divided and prefabricatedAfter pouring into the hole, pouringPrefabricated is to direct the already installed loading, hit with a pile driver
