Foundation pit construction method based on micro-disturbance construction method pile
The invention provides a foundation pit construction method based on a micro-disturbance construction method pile. The construction method comprises the steps of construction preparation, temporary wall reinforcement and roof dismantling, micro-disturbance construction method pile construction, earth excavation, coping beam construction, first steel pipe supporting, earth excavation to bottom elevation of second supporting, enclosing purlin and second steel pipe supporting construction, earth excavation to bottom elevation of a basement bottom plate cushion layer, (basement bottom plate construction completion), second steel supporting dismantling, (negative two-story structure construction completion), first steel supporting dismantling, (negative one-story structure construction completion) and void grouting after profile steel pulling. Foundation pit construction is conducted in an existing building, a micro-disturbance construction method is used for driving the construction method pile in a foundation pit, the disturbance to the existing old building is reduced, and the construction safety is improved.
本发明提供一种基于微扰动工法桩的基坑施工工法，工法包括：施工准备→墙体临时加固及屋面拆除→微扰动工法桩施工→土方开挖→压顶梁施工→第一道钢管支撑→土方开挖至第二道支撑底标高→施工围檩和第二道钢管支撑→土方开挖至地下室底板垫层底标高→(地下室底板施工完成)→拆除第二道钢支撑→(负二层结构施工完成)→拆除第一道钢支撑→(负一层结构施工完成)→型钢拔除后空隙注浆，在既有建筑的中进行基坑施工，使用微扰动工法对基坑进行工法桩打设，降低对既有老旧建筑的扰动，提高施工的安全性。
