Tubular pile grouting type expanded bore pile for geology with sand and stone clamped in sludge and construction method of tubular pile grouting type expanded bore pile
The invention provides a tubular pile grouting type expanded bore pile for the silt and sand-mixed geology and a construction method of the tubular pile grouting type expanded bore pile, and relates to the field of building construction. The device comprises a plurality of pipe piles which are coaxially arranged, a positioning pipe is arranged at the end, facing the other pipe pile, of one pipe pile, and every two adjacent positioning pipes are welded to each other; the outer side of the bottommost tubular pile is sleeved with a geotechnical cloth bag, an opening of the geotechnical cloth bag is hooped on the outer wall of the bottommost tubular pile, and grouting pipes are arranged in the multiple tubular piles in a penetrating mode and used for conveying cement mortar to the geotechnical cloth bag. The construction method has the characteristic of improving the construction efficiency and the base expanding effect of the base expanding pile.
本申请提供了一种淤泥夹砂石地质用管桩注浆型扩底桩及其施工方法，涉及建筑施工领域。其包括若干同轴设置的管桩，一个管桩朝向另一个管桩的一端设有定位管，相邻两个定位管之间相互焊接；位于最下方的所述管桩的外侧套设有土工布袋，所述土工布袋的开口箍扎在位于最下方的所述管桩的外壁上，若干所述管桩内穿设有注浆管，所述注浆管用于向所述土工布袋输送水泥砂浆。本申请具有提高扩底桩施工效率及扩底效果的特点。
