End-bearing type threaded displacement pile forming equipment and pile forming construction method
The invention discloses end-bearing type threaded displacement pile forming equipment and a pile forming construction method. The end-bearing type threaded displacement pile forming equipment and the pile forming construction method have the advantages that a 'solid base' is formed at the bottom of a pile body by means of ejecting cement paste at the bottom of the pile body, so that resistance of the bottom of the pile body is enhanced, and piercing of the bottom of the pile body is controlled effectively; a section of the formed pile body is thread-shaped, and a thread of the pile body is meshed with a soil thread beside a pile tightly, so that frictional resistance around the pile is improved obviously, vertical bearing capacity of the single pile is improved remarkably, the designed pile length can be decreased effectively, and engineering cost is reduced; pile forming is synchronously finished when pile body grouting is finished, so that construction period is shortened obviously, and construction efficiency is improved; soil beside the pile body is squeezed and densified during pile forming, so that performance of the soil around the pile body can be improved, a long-term function of a pile foundation is benefited, outward waste slag transport, site mud pollution and site mud treating are avoided fundamentally, and civilized construction is achieved.
