Full-lead-hole construction method for PHC tubular pile under complex geological conditions of deep sand layer
The invention discloses a PHC (prestressed high-strength concrete) tubular pile full-lead-hole construction method under a deep sand layer complex geological condition, which adopts full-lead-hole construction, can solve the problem of construction difficulty of a deep sand interlayer PHC tubular pile, is stable and reliable, and has popularization reference significance. Compared with the measure of replacing the pile tip type, the full guide hole construction plays a great role; the method is widely applied to friction type pipe piles or friction-end bearing type pipe piles; compared with hammering method construction and full guide hole matched static press construction, the construction method has the advantages of being convenient to construct, high in work efficiency, good in pile forming quality and the like, and the friction coefficient of a pile body and a soil body is prevented from being reduced; the method breaks through the current specification suggested value, has certain degree of innovation, and accumulates experience for pipe pile construction under similar geological conditions.
本发明公开了一种深厚砂层复杂地质条件下PHC管桩全引孔施工方法，本发明采取全引孔施工，可解决深厚砂夹层PHC管桩施工困难，施工方法稳定可靠，具有推广借鉴意义；相比于更换桩尖类型措施，全引孔施工发挥作用较大；本发明广泛应用于摩擦型管桩或摩擦‑端承型管桩；本发明相比于锤击法施工，全引孔配合静压机施工，具有施工方便、工效高，成桩质量好等优点，避免桩体与土体摩擦系数降低；本发明突破现行规范建议值，具有一定程度创新，为类似地质条件管桩施工积累经验。
