Spiral soil squeezing recompaction cast-in-place concrete pile, pile forming drill bit and construction method
The invention relates to a spiral soil squeezing recompaction cast-in-place concrete pile, a pile forming drill bit and a construction method. According to the adopted technical scheme, the spiral soil squeezing recompaction cast-in-place concrete pile comprises a primary soil squeezing pile section and a plurality of recompaction sections, the primary soil squeezing pile section is a concrete pile I, concrete piles II arranged inside the recompaction sections, the outer diameter of the concrete piles II is larger than that of the concrete pile I, the concrete piles II are wrapped by a recompaction layer formed by mixing rock soil and concrete, and the concrete pile I and the concrete piles II are of an integrated structure. The spiral soil squeezing recompaction cast-in-place concrete pile can carry out strengthened compaction on a rock soil layer with the large compressibility in the pile depth range, the pile bearing capacity is further improved, and energy conservation and emissionreduction are achieved.
本发明创造涉及螺旋挤土复挤密混凝土灌注桩及成桩用钻头及施工方法。采用的技术方案是：螺旋挤土复挤密混凝土灌注桩，包括一次挤土桩段和若干段复挤密段；所述一次挤土桩段为混凝土桩Ⅰ，所述复挤密段为，内部为混凝土桩Ⅱ，混凝土桩Ⅱ的外径大于混凝土桩Ⅰ的外径，混凝土桩Ⅱ外包裹为由岩土与混凝土混合的复挤密层，混凝土桩Ⅰ和混凝土桩Ⅱ为一体结构。本发明创造的螺旋挤土复挤密混凝土灌注桩在桩深范围内，可对压缩性大的岩土层进行加强挤密，进一步提高桩承载能力，节能减排。
