Design and construction of pressure-groutedreinforcement for drilled pile
Zeng Wei Xu Wu(Jiangxi provincial Institute of chemical Industry Nanchang 330002)
In the base work of the building in chemical plant,due to excessive bottom sttlings, pile load Capacity is not strong enough to support the building. The pile can be reinforced by two ways. One is to drill holes on pile shaft, then flush the holes and finally grout the holes under pressure. the other is to increase the adhesion between pile shaft, pile tip and basement concrete.
