The construction process of pipe pile

The construction process of pipe pile: This project venue silt audience distribution, maximum thickness of 13.5 meters at the pile tip bearing layer is relatively hard weathered granite layer; taking into account the construction of pile construction process of hammering method, and static construction pile pressure method compared to pile more likely to cause cracks, especially in the silt soil, thereby reducing corrosion resistance pile, the design requirements hydrostatic method construction. In addition, static method of construction on the site soil endurance higher, the case of large-scale construction of "squeezing effect" is obvious. Therefore, the construction should take measures to avoid the pile driver "trap machine", "tilt" cause Piles inclined cracks or fracture, as can pile on the backfill surface routes within the scope of artificial compaction or before construction mechanical rolling compaction; measures should be taken to avoid "squeezing effect" makes the pile "deviation" and "floating pile" pile caused cracks and, if necessary, can be preset in the range of pile foundation intensive "observation post" in pressure piles at any time during the observation "observation post" the deviation and the amount of floating pile, ready to adjust the pressure line and the pressure piles pile intervals to avoid pile cracks. Cracks appear inevitably pile pile of reducing corrosion resistance, durability and impact pile of carrying capacity.

In the coastal geology corrosive environment, especially when the medium - highly corrosive groundwater environment, using a solid foundation in the form of pile foundation pile is preferred. But when using solid foundation piles subject to conditions or a higher cost, to take adequate precautions, you can still consider using prestressed pipe pile foundation, its durability and use of safety can be guaranteed.
