Cast-in-place pile with enlarged-diameter conical pile sections, drill bit for pile forming and pile forming construction method
The invention relates to a cast-in-place pile with enlarged-diameter conical pile sections, a drill bit for pile forming and a pile forming construction method. The cast-in-place pile with the enlarged-diameter conical pile sections comprises a main body cylindrical cast-in-place pile and a conical pile bottom, wherein a plurality of enlarged-diameter conical pile sections of an integrated structure are manufactured on the outer edge of the main body cylindrical cast-in-place pile, and the enlarged-diameter conical pile sections comprise one or two of enlarged-diameter conical thread pile sections and enlarged-diameter conical re-compaction pile sections; the enlarged-diameter conical thread pile sections are structurally characterized in that threads I of an integrated structure are manufactured on the outer edge of the main body cylindrical cast-in-place pile, and the outer edges of the whole threads I form a conical body; and the enlarged-diameter conical re-compaction pile sections are structurally characterized in that re-compaction column pile sections are manufactured on the upper portion of the outer edge of the main body cylindrical cast-in-place pile, re-compaction conical pile sections are manufactured on the lower portion of the outer edge of the main body cylindrical cast-in-place pile, and the outer edges of the re-compaction column pile sections and the outer edges of the re-compaction conical pile sections are wrapped with re-compaction reinforcing layers. The cast-in-place pile is high in bearing capacity, energy-saving and environment-friendly.
本发明创造涉及一种带有扩大径锥形体桩段的灌注桩及成桩用钻头和成桩施工方法。所述带有扩大径锥形体桩段的灌注桩包括主体柱形灌注桩和锥形桩底，所述主体柱形灌注桩外缘上制有若干段一体结构的扩大径锥形体桩段，所述扩大径锥形体桩段包括扩大径锥形体螺牙桩段和扩大径锥形体复挤密桩段的一种或二种；所述扩大径锥形体螺牙桩段的结构是在主体柱形灌注桩的外缘制有一体结构的螺牙Ⅰ，整体螺牙Ⅰ的外缘构成锥形体；所述扩大径锥形体复挤密桩段的结构是在主体柱形灌注桩的外缘制有一体结构的上部为复挤密柱体桩段和下部为复挤密锥体桩段，复挤密柱体桩段和复挤密锥体桩段的外缘包裹一层复挤密增强层。本发明创造的灌注桩承载能力高、节能环保。
