1 薄壁沉井技术及其特点薄壁沉井技术是指因设计或施工需要,在地下工程周围增设一定高度的竖向钢筋混凝土薄板墙(导沉薄壁),并通过底板与原结构相联成一整体,以满足工程设计或施工某种要求的技术措施。这项技术具有以下特点:1.1 该技术与沉井技术施工方法相近,结构在现场浇筑,通过取土下沉方式没入土中,但沉井是利用原结构的外壁导沉,而该技术是利用增设的钢筋
1 thin-walled sunk well technology and its characteristics Thin-walled sunk well technology refers to the need to design or construction, in the underground works to add a certain height of vertical reinforced concrete thin-walled wall (thin walled), and through the floor and the original structure phase United into a whole, to meet the engineering design or construction of certain requirements of technical measures. The technology has the following characteristics: 1.1 The technology and caisson technology similar to the construction method, the structure pouring in the field, by soil subsidence sinking into the soil, but the caisson is the use of the outer wall of the original structure of Shen Shen, and the technology is to use Additional reinforcement
