Vacuum dewatering combined in-hole dynamic compaction gravel composite pile soft foundation treatment construction method
The invention discloses a vacuum dewatering combined in-hole dynamic compaction gravel composite pile soft foundation treatment construction method, and belongs to the technical field of soft soil foundation treatment. According to the construction method, dewatering well pipes are arranged in a quincunx shape, the distance is equal to that of tamping points, the tamping points are processed through in-hole dynamic compaction gravel piles, and the dewatering well pipes are arranged in the quincunx shape; the in-hole dynamic compaction gravel pile is provided with three stages of dynamic compaction layers, and the three stages of dynamic compaction layers are sequentially widened from bottom to top; the in-hole dynamic compaction gravel pile is used as a moisture suction passage of a deep soft soil layer, so that the transverse penetration effect of vacuum suction is effectively enhanced; the method has the advantages of being simple in construction process, high in construction speed, good in treatment effect, stable in later-stage quality, economical and environmentally friendly.
本发明公开一种真空降水联合孔内强夯碎石复合桩软基处理施工方法，属于软土地基处理技术领域。本发明施工方法采用降水井管，按梅花型布置，间距同夯点间距，夯点采用孔内强夯碎石桩处理，梅花形布置；孔内强夯碎石桩设三级强夯层，三级强夯层自下至上依次变宽；通过孔内强夯碎石桩作为深层软土土层的水气抽吸通路，有效增强了真空抽吸的横向穿透效果；该方法具有施工工艺简单、施工速度快、处理效果好、后期质量稳定、经济环保的优点。
