Construction method of multi-layer reinforced gravel pile
The invention discloses a construction method of a multi-layer reinforced gravel pile. The construction method comprises the following steps that S1, a pile body material is selected; s2, a geosynthetic material wrapping layer is selected and manufactured according to the property of soil around the pile; s3, judging a field soil layer; s4, a pile forming manufacturability test is conducted, and a compaction method construction scheme is obtained; s5, construction by a compaction method; s6, a pile forming manufacturability test is conducted, and a replacement method construction scheme is obtained; and S7, construction by a replacement method. Compared with the pure construction of the geogrid reinforced gravel pile, the multi-layer reinforced gravel pile comprising the geosynthetic material wrapping layer is wrapped with the geotextile, so that the requirement on the construction precision is higher, and the method can protect the integrity of the geotextile to the maximum extent. The geotextile can achieve the effects of draining water and blocking flowing of fine particles, it is guaranteed that the gravel pile serves as a drainage channel all the time under the long-term service effect, consolidation of a soft soil foundation is accelerated, and dissipation of excess pore water pressure of a liquefiable site is promoted during an earthquake.
本发明公开了一种多层加筋碎石桩的施工方法，包括以下步骤：S1，选取桩体材料；S2，根据桩周土的性质选取和制作土工合成材料包裹层；S3，判断现场土层；S4，进行成桩工艺性试验，获得挤密法施工的方案；S5，挤密法施工；S6，进行成桩工艺性试验，获得置换法施工的方案；S7，置换法施工。与单纯的对土工格栅加筋碎石桩的施工相比，包含土工合成材料包裹层的多层加筋碎石桩由于包裹有土工织物，对施工精度要求更高，此方法能最大限度保护土工织物的完整性。土工织物可以起到排水和阻隔细颗粒流动的作用，保证碎石桩在长期服役作用下一直作为排水通道，加速固结软土地基并在地震时促进消散可液化场地超孔隙水压力。
