Tunnel push-out type joint deviation correcting system and construction method
The invention discloses a tunnel push-out type joint deviation correcting system which comprises a push-out type joint and anchoring piles arranged at the two radial sides of the push-out type joint; a winch is installed on the top of each anchoring pile; at least two fixed pulleys are arranged on each anchoring pile in the vertical direction; the two radial sides of the push-out type joint are respectively provided with a deviation correcting lug seat; and steel wire ropes wound on the winches penetrate through the fixed pulleys and are connected with the deviation correcting lug seats. When the push-out type joint is pushed out, if deviation occurs, the winches tighten the steel wire ropes to pull the push-out type joint to rectify deviation. The invention further discloses a corresponding construction method of a push-out type final joint deviation correcting system for a steel shell concrete immersed tube tunnel. The tunnel push-out type joint deviation correcting system is simple, the construction method is easy and convenient, when the push-out type joint is pushed out of a steel shell, the push-out type joint can be pulled through the winches to conduct timely deviation correction according to deviation generated when the push-out type joint is pushed out of the steel shell, and the butt joint efficiency is improved.
本发明公开一种隧道推出式接头纠偏系统，包括推出式接头及设置在所述推出式接头径向两侧的锚固桩，每一所述锚固桩的顶部安装有卷扬机，所述锚固桩上沿垂直方向设置有至少两个定滑轮，所述推出式接头径向两侧分别设有纠偏耳座，所述卷扬机上缠绕的钢丝绳穿过所述定滑轮并与所述纠偏耳座连接，所述推出式接头在推出时，如发生偏移则通过所述卷扬机收紧钢丝绳拉动所述推出式接头进行纠偏。本发明还公开相应的一种钢壳混凝土沉管隧道推出式最终接头纠偏系统的施工方法。本发明结构简单，施工方法简便，在推出式接头推出钢壳时能够根据其推出发生的偏移通过卷扬机拉动推动式接头进行及时的纠偏，提高对接效率。
