[导读]: 钢接头内圈连接钢板与外圈连接钢板同样处理, 其区别仅是吊耳焊接位置不同。通过该方法处理了顶墙以及侧墙部分连接钢板组件,最终悬挂到最终接头上的连接钢板约占连接钢板总量的25%, 这也就大大减少了相应连接钢板现场的搬运及安装。

钢接头连接钢板悬挂

在工厂内将部分连接钢板组件悬挂到最终接头结构上,以此来减少现场钢接头连接钢板搬运,安装的工作量。

在最终接头钢结构的倾斜面上焊接耳板,连接钢板组件上同样焊接相配套的耳板组合件,并利用销轴连接耳板和耳板组合件。钢接头内圈连接钢板与外圈连接钢板同样处理, 其区别仅是吊耳焊接位置不同。通过该方法处理了顶墙以及侧墙部分连接钢板组件,最终悬挂到最终接头上的连接钢板约占连接钢板总量的25%, 这也就大大减少了相应连接钢板现场的搬运及安装。

The steel connector connects the steel plate suspension

In order to reduce the work load of handling and installation of steel joint joint plate, some parts of the joint plate assembly are suspended to the final joint structure in the factory.

The lugs are welded on the inclined surface of the final joint steel structure, and the lug assembly is also welded on the connecting steel plate assembly, and the lug assembly and the lug assembly are connected by the pin shaft. Steel joint inner ring connection steel plate and outer ring connection steel plate are treated the same, the difference is only the lifting lug welding position is different. Through this method, the top wall and part of the side wall connection steel plate assembly are processed, and the connection steel plate finally hanging to the final joint accounts for about 25% of the total connection steel plate, which greatly reduces the corresponding connection steel plate field handling and installation.

钢接头部分隔板改造

在对钢接头连接钢板施焊前,顶推小梁的临时支撑管是要拆除的。拆除临时支撑的同时,顶推小梁所受外力将会发生变化,这就可能导致顶推小梁发生不可控的位移,止水橡胶就可能受到破坏,其带来的后果就是结合腔内止水失效,这对整个沉管隧道来说,是灾难性的。为了确保这一情况不会发生,我们在顶推小梁钢管拆除前,对结构先行加固。在狭小的空间内,如新增结构加固,将会增加焊接难度,使焊接质量变得更难以控制,最可靠的方案就是对已有结构进行改造。

钢接头结构是由连接钢板与隔板组成,对部分隔板结构进行改造,将隔板改成纯“工”字型结构(去除原先的小加劲板),其上翼缘板为外圈连接钢板,腹板为隔板,下翼缘板为内圈连接钢板,并在上翼缘顶部增设垫板。

对于整圈钢接头来说,我们改造的隔板涉及到顶墙区域四处,侧墙区域两处,底墙区域七处,改造的隔板结构在临时撑管拆除(或部分拆除)前先行焊接,加固顶推小梁,从而避免结合腔止水失效的情况发。

Modification of steel joint partition

The temporary support pipe pushing the trabeculae is to be removed before welding the steel connector to the steel plate. When the temporary support is removed, the external force on the pushing trabecular beam will change, which may lead to uncontrollable displacement of the pushing trabecular beam, and the water-stop rubber may be damaged. The result is combined with the failure of water stop in the cavity, which is disastrous for the whole immersed tube tunnel. To ensure that this will not happen, we will reinforce the structure before removing the trabecular steel pipe. In a narrow space, if the new structure reinforcement, will increase the difficulty of welding, welding quality becomes more difficult to control, the most reliable program is to transform the existing structure.

The steel joint structure is composed of connecting steel plate and baffle plate. Part of the baffle plate structure is transformed and the baffle plate is changed into pure "h" type structure (the original small stiffening plate is removed). The upper flange plate is the outer ring connection steel plate, the web plate is the baffle plate, and the lower flange plate is the inner ring connection steel plate.

For the whole circle of steel joints, the baffle we modified involves four areas of the top wall, two areas of the side wall and seven areas of the bottom wall. The baffle structure is welded before the temporary support pipe is removed (or partially removed), and the trabecula is strengthened to avoid the failure of water stop in the cavity.

通过钢接头连接钢板分块的优化,连接钢板的悬挂以及隔板结构的改造,降低了现场焊接的工作量和施工难度,提高现场结构的安全性,为隧道后续混凝土浇注和最终隧道的全线贯通铺平道路。

Through the optimization of steel connector connecting steel plate, the suspension of connecting steel plate and the transformation of diaphragm structure, the workload and construction difficulty of on-site welding were reduced, the safety of on-site structure was improved, and the road was paved for the subsequent concrete pouring of the tunnel and the completion of the tunnel.
