Reverse construction method upside-down well construction process
The invention provides a reverse construction method upside-down well construction process. The reverse construction method upside-down well construction process comprises the following steps that 1, construction preparation is conducted; step 2, field leveling; step 3, paying off and positioning; 4, hole guiding through a geological drilling machine; 5, double-liquid grouting is carried out; step 6, breaking the concrete pavement; step 7, manufacturing an intercepting ditch and a water-collecting well; step 8, construction of an I-shaped section; step 9, construction of a type II section; step 10, constructing a type III section; step 11, construction of an IV type section; 12, a drainage ditch and a water collecting well are excavated; 13, the bottom of the well pit is cleared and leveled; 14, a cushion layer is poured; 15, construction of the catch basin; and step 16, road surface recovery. According to the method, foundation pit excavation supporting is simple, large equipment such as a pile driver is not involved, the corresponding work amount is small, the well wall can be manufactured after the first section of the foundation pit is excavated, and the construction period is shortened. In the subsequent excavation construction process, only one long-arm excavator is needed to be matched to complete foundation pit excavation construction.
本发明提供了一种逆作法倒挂井施工工艺，包括以下步骤：步骤1，施工准备；步骤2，场地平整；步骤3，放线定位；步骤4，地质钻机引孔；步骤5，双液注浆；步骤6，混凝土路面破除；步骤7，截水沟及集水井制作；步骤8，Ⅰ型节段的施工；步骤9，Ⅱ型节段的施工；步骤10，Ⅲ型节段的施工；步骤11，Ⅳ型节段的施工；步骤12，排水沟及集水井开挖；步骤13，清平井坑底；步骤14，浇筑垫层；步骤15，截流井施工；步骤16，路面恢复。本发明的方法开挖基坑支护简单，不涉及打桩机等大型设备，相应工程量少，在基坑开挖完第一节后即可制作井壁，节省工期。在后续开挖施工时，仅需一台长臂挖掘机即可配合完成基坑开挖施工。
