【中外运沙伦氏】荷兰海牙盾构机运输及安装工程

此次项目包含三个阶段:

1. 将盾构机运输至海牙现场并进行安装。

2. 在第一条隧道挖穿后将盾构机拆解并运输至第二条隧道起点。

3. 在第二条隧道挖穿后将盾构机拆解并运走。

沙伦氏(Sarens)目前已完成第二阶段的工作。为进行第三阶段工作,盾构机需要被拆解成部件,运输至第二条隧道起点后再进行安装。

这项工程也带来不少挑战。例如,盾构机拆解的最后一个部件却需要第一个进行组装。因此团队需要谨慎地计划整个转移操作,以尽可能缩短等待时间。

另外,虽然大部分盾构机部件能通过公路进行运输,但由于质量和尺寸的原因。有6个部件必须由SPMT和驳船来进行运输。这些部件尺寸约8.4*8.4米,包含一台重130吨的驱动装置。特别的是,还有一台直径118米,重115吨的刀盘。

由于道路和桥梁的宽度无法容纳刀盘的直径,因此刀盘无法在水平状态下运输。为了解决这个问题,沙伦氏(Sarens)团队设计了一个能使刀盘垂直运输的支架。团队将刀盘放在这个支架上,这样就可以将刀盘从SPMT吊装到驳船上,运输到目的地后再吊装至SPMT。

转移阶段的工作使用了以下设备:

•350T 履带吊 (CC2800-1)

•24 轴线  SPMT

•700吨汽车吊

•45*7*1.9 米驳船

所有的盾构机部件转移操作都在晚间进行,共进行两晚。因为700T汽车吊必须在公路进行吊装,而白天操作会影响正常交通。此外,用于拆解盾构机的履带吊也必须转移至接收井以进行盾构机的重新安装。

The operation involves three distinct phases: 

1. Transport and assembly of a tunnel boring machine (TBM) to a site in The Hague.

2. Intermediate transport of TBM parts back to the launch shaft after boring of the first tunnel.

3. After boring of the second tunnel, disassembly and transport of the TBM.

Sarens recently completed Phase 2 of the project. To do phase 3, Sarens had to first disassemble the TBM, transport it piece by piece, and then reassemble it so that it could bore a second tunnel. 

This operation came with very particular challenges, however. For example, the last part of the TBM to be disassembled was also the first part required for reassembly. The team had to carefully plan the entire transfer operation so as to minimize downtime.

Furthermore, while most of the TBM parts could undergo normal road transport, six parts had to be specially transferred by SPMT and barge due to their weight and dimension. These shield parts measured approximately 8.4 x 8.4m with a 130T main drive and, most notably, a 115T cutting wheel with an 11,8m diameter. 

The cutting wheel could not be transported horizontally because both roads and bridges were too narrow to accommodate its size. To address this issue, Sarens created a support that allowed for vertical transport. The crew fixed the support to the cutting wheel so it could be lifted in one piece during transfer from the SPMTs to the barge, and then back to the SPMTs again.

For this transfer operation, Sarens used the following equipment: 

•350T crawler crane (CC2800-1)

•24 axle lines SPMT

•Mobile cranes up to 700T

•River barge measuring 45x7x1.9 metres 

All the TBM parts were transferred over the course of two nights, as the 700T crane had to be removed during the daytime to accommodate traffic on the public road. Additionally, the crawler crane used for disassembly had to be demobilized, transported, and remobilized at the reception shaft so it could assist with the TBM\'s reassembly.
