Construction method for rigid pile composite foundation
The invention discloses a construction method for a composite foundation. The method mainly comprises the following steps that firstly, rigid pile point positions and granular pile point positions in a construction area are determined; secondly, at the rigid pile point positions, construction of rigid piles is carried out; thirdly, at the granular pile point positions, construction of granular piles is carried out; and fourthly, a mattress layer is laid on the surface of a construction site, and the composite foundation is formed. Through combination of down-hole dynamic consolidation and rigid pile construction, losses of side extrusion of dynamic compaction inside the hole can be greatly reduced, the down-hole dynamic consolidation is improved, and bearing force of earth among the piles and the granular piles is fully exerted. Therefore, according to the method, the bearing force between the earth among the piles and the granular piles is fully utilized, under the condition that the number of the rigid piles is small, the composite foundation can achieve the bearing force obtained only through many rigid piles, the cost is reduced, and the construction efficiency is improved.
