Photovoltaic support prefabricated pipe pile foundation construction method under stone-containing soil condition
The invention provides a construction method for a photovoltaic support prefabricated pipe pile foundation under the condition of stone-containing soil. The construction method comprises the steps that S1, a site is leveled; s2, pile position paying-off; s3, guiding a hole through a down-the-hole drill; s4, auxiliary steel pile reaming is carried out, if auxiliary steel pile reaming is blocked, the step S5 is carried out, and otherwise, the step S7 is carried out; s5, secondary splitting and chambering are conducted, specifically, the blocked auxiliary steel pile is pulled out, and a plunger type hydraulic splitting rod is adopted to be placed in the original down-the-hole drill hole guiding position for secondary splitting and chambering; s6, secondary reaming of the auxiliary steel pile; s7, checking and accepting formed holes; s8, pressing the prefabricated pipe pile in place; s9, correcting the deviation; s10, reinforcing the composite cement soil slurry; and S11, heat preservation and maintenance. According to the method, the applicability problem of the photovoltaic support prefabricated pipe pile foundation under the rock-containing geological condition is ingeniously solved, the prefabricated pipe pile with good economical efficiency continues to be used under the geological condition, use of foundation types such as a concrete cast-in-place pile with low economic indexes, low environmental protection performance and low recoverability is avoided, construction is convenient, the cost is low, and the method is suitable for large-scale popularization and application. And the method has relatively high popularization and application values.
本发明提供了一种含石土质条件下的光伏支架预制管桩基础施工方法，包括：S1场地平整；S2桩位放线；S3潜孔钻引孔；S4辅助钢桩扩孔：若辅助钢桩扩孔受阻则进入步骤S5，否则，进入步骤S7；S5二次劈裂扩孔：将受阻的辅助钢桩拔出，采用柱塞式液压劈裂棒放入原有潜孔钻引孔位置中进行二次劈裂扩孔；S6辅助钢桩二次扩孔；S7成孔验收；S8预制管桩压桩就位；S9纠偏；S10复合水泥土浆补强；S11保温和养护。本发明巧妙解决了光伏支架预制管桩基础在含岩石地质条件下的适用性问题，使经济性良好的预制管桩在此类地质条件下继续适用，避免了混凝土灌注桩等经济指标、环保性和可回收性不强的基础型式的使用，施工方便，成本经济，具有较强的推广应用价值。
