【中外运沙伦氏】荷兰海牙盾构机运输及装置工程

这次项目包括三个阶段:

1. 将盾构机运输至海牙现场并停止装置。

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终点。

3. 在第二条隧道挖穿后将盾构机拆解并运走。

沙伦氏(Sarens)现在已完成第二阶段的任务。为停止第三阶段任务,盾构机需求被拆解成部件,运输至第二条隧道终点后再停止装置。

这项工程也带来不少应战。比方,盾构机拆解的最初一个部件却需求第一个停止组装。因而团队需求慎重地方案整个转移操纵,以尽能够延长等候日期。

别的,固然大局部盾构机部件能经过公路停止运输,但由于质量和尺寸的缘由。有6个部件必需由SPMT和驳船来停止运输。这些部件尺寸约8.4*8.4米,包括一台重130吨的驱动安装。特殊的是,另有一台直径118米,重115吨的刀盘。

由于路途和桥梁的宽度无法包容刀盘的直径,因而刀盘无法在程度形态下运输。为理解决这个题目,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,如许就可以将刀盘从SPMT吊装到驳船上,运输到目标地后再吊装至SPMT。

转移阶段的任务运用了以下设置装备摆设:

•350T 履带吊 (CC2800-1)

•24 轴线  SPMT

•700吨汽车吊

•45*7*1.9 米驳船

一切的盾构机部件转移操纵都在晚间停止,共停止两晚。由于700T汽车吊必需在公路停止吊装,而白昼操纵会影响正常交通。别的,用于拆解盾构机的履带吊也必需转移至接纳井以停止盾构机的重新装置。

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.
