Construction method of gravel pile penetrating through rubble layer
The invention provides a rubble layer penetrating gravel pile construction method which comprises the steps of field investigation, measurement positioning, pile machine in-place, pile pipe sinking, gravel pouring, first-time pipe pulling vibration, gravel pouring while pipe pulling during vibration, pile forming and the like. The stability of the gravel pile machine is guaranteed through the rubble layer site, it can be guaranteed that the guide frame is perpendicular to the ground, the differential settlement risk of a roadbed is reduced, safety accidents are effectively avoided, meanwhile, the gravel pile construction technology is optimized, the construction efficiency is improved, and the construction cost is reduced. The adopted pile pipe structure can ensure that the pile head can smoothly penetrate through a backfilled rubble layer, the reverse insertion construction effect of the gravel pile is improved, the rotation angle of the reverse insertion pressing plate is limited through the reverse insertion check ring and the check block, it is ensured that the reverse insertion pressing plate can press gravel in the reverse insertion process of the gravel pile, and the construction quality of the gravel pile is further improved; and large-scale popularization and application can be realized.
本发明提供一种穿越片石层的碎石桩施工方法，包括现场勘察、测量定位、桩机就位、桩管下沉、碎石灌入、首次拔管振动、边振动边拔管边灌碎石、成桩等步骤，本发明提供的穿越片石层的碎石桩施工方法，片石层场地使得碎石桩机的平稳得到保障，能够保障导向架与地面垂直，降低了路基的不均匀沉降风险，有效避免安全事故的发生，同时优化碎石桩施工工艺，提高施工效率，降低施工成本。所采用的桩管结构能够确保桩头能顺利穿过回填的片石层，提升碎石桩反插施工效果，通过反插挡圈与挡块限制反插压板的旋转角度，确保反插压板能够在碎石桩在反插工序中压紧碎石，进一步提升碎石桩的施工质量，能够实现大范围的推广应用。
