Anti-sliding construction method for unbalance loading steel cofferdam and anti-sliding structure of unbalance loading steel cofferdam
The invention discloses an anti-sliding construction method for an unbalance loading steel cofferdam and an anti-sliding structure of the unbalance loading steel cofferdam. The anti-sliding construction method comprises the steps that the steel cofferdam is arranged at a preset position on one side of a slope body and abuts against the slope body; the top, abutting against the steel cofferdam, of the slope body is subjected to flattening treatment; a plurality of notches for mounting anchoring piles are formed in the top of the slope body, and mounting grooves for communicating the notches with the steel cofferdam are formed in the top of the slope body; the anchoring pile is placed in the notch, and the anchoring pile is inserted and driven until the first preset requirement is met; the steel cofferdam is inserted and hit until a second preset requirement is met; at least one connecting part is laid in the mounting groove, and the two ends of the connecting part are fixedly connected with the anchoring piles and the steel cofferdam correspondingly; tensioning and anchoring the connecting part until the prestress of the connecting part reaches a preset standard; and concrete is poured on the connecting part for covering protection. The pressure of a slope body on the single side of the steel cofferdam is effectively counteracted, the requirement for counteracting unbalanced side pressure in the deep foundation pit cofferdam under the similar complex geological conditions is met, and the construction period is effectively shortened.
一种偏载钢围堰抗滑移的施工方法及其抗滑移结构，包括：将钢围堰置于坡体一侧的预定位置并与坡体抵接；对与钢围堰抵接的坡体顶部进行平整处理；在坡体顶部开设多个用于安装锚固桩的槽口，并与坡体顶部开设有连通槽口与钢围堰的安装槽；将锚固桩置于槽口内，对锚固桩实施插打，直至达到第一预定要求；对钢围堰进行插打操作，直至达到第二预定要求；在安装槽内铺设至少一个连接部，连接部两端分别固定连接锚固桩和钢围堰；张拉锚固连接部，直至连接部的预应力达到预定标准；在连接部上浇筑混凝土覆盖保护。本发明有效抵消坡体对钢围堰单侧的压力，满足同类复杂地质条件下深基坑围堰中抵消不平衡侧压力要求，有效缩短施工工期。
