Counter-force supporting open caisson bottom sealing construction method
The invention discloses a counter-force support open caisson bottom sealing construction method, which relates to a building method and comprises the following steps: step A, sinking an open caisson to a design position without draining water; b, bottom sealing concrete is poured below the waterline in the open caisson till the bottom sealing is formed in the design position; c, after bottom sealing concrete pouring is completed, a counter-force supporting device is installed immediately; d, after the bottom sealing concrete reaches the design strength, accumulated water in the open caisson is pumped; f, reinforcing steel bars used for bottom plate pouring are bound to the sealing bottom; and G, bottom plate concrete is poured, and then concrete curing is conducted. Compared with the prior art, the thickness of the bottom sealing concrete can be effectively reduced, the thickness of the bottom sealing concrete can be reduced by 40%, materials are saved, cost is reduced, and the counter-force supporting device can be adjusted according to open caissons of different sizes.
本发明公开了一种反力支撑的沉井封底施工方法，涉及一种建筑方法，包括以下几个步骤：步骤A：沉井不排水下沉直至设计位置；步骤B：向沉井内水线下灌注封底混凝土直至设计位置形成封底；步骤C：封底混凝土浇筑完成后立即安装反力支撑装置；步骤D：当封底混凝土达到设计强度后将沉井内的积水抽取；步骤F：在封底上绑扎用于底板浇筑的钢筋；步骤G：浇筑底板混凝土，然后进行混凝土养护。与现有技术相比，通过本申请可有效减少封底混凝土的厚度，封底混凝土的厚度可减少40%，节约了材料，降低了成本，并且反力支撑装置可根据不同大小的沉井进行调整。
