首次采用长方形钻凿机挖掘地下道

为了不干扰地面上的交通流量，兴建中的汤申—东海岸线两个地铁站的地下行人通道将采用中国中铁装备集团研制的新的长方形隧道钻凿机建造，可节省约30％的人力。

这是本地首次采用长方形的钻凿机，传统的隧道钻凿机是圆形的。

合乐（Havelock）站和史蒂芬（Stevens）站的地下行人通道建在繁忙的交通路口和道路之下，地底下已铺有许多水管和电缆等设施。如果使用传统的随挖随铺法（cut and cover）建造地下行人通道，将得进行多次交通改道，影响车流量。

陆路交通管理局于是采用无开挖（trenchless）技术兴建地下通道，工程分包商中国中铁隧道集团引进长方形隧道钻凿机进行挖掘，以避免干扰路面上的活动，也可减低噪音和灰尘，提高生产力。

合乐站的地下行人通道约长150米，挖掘工程已在上月动工，预计9月前挖好。到明年初，长方形隧道钻凿机将运到史蒂芬站工地挖掘60米长的地下通道。

新的隧道钻凿机耗资约650万元，但可节省30%的人力，也可明显缩短挖掘地下通道的工程时间。

New tunnel-boring machine makes cutting corners perfectly sound

SINGAPORE -The Land Transport Authority has become the first to use a rectangular tunnel-boring machine here, paving the way for future rail and road projects which could be speedier, cleaner and significantly less disruptive.

The first rectangular tunnel-boring machine - which excavates rectangular instead of circular tunnels -was deployed on May 11 for an underpass at the MRT Thomson-East Coast Line's Havelock MRT station.

Using a set of six cutter heads, the machine supplied by China Railway Engineering Equipment Group has since completed about 20 per cent of the 150m underground pedestrian walkway that goes under Zion Road to give commuters of the future line easy access to current and future developments in the area.

This new construction method is four times the cost of a cut-and-cover method, but LTA project director Henry Foo said it saves time, manpower and is far less disruptive.

A cut-and-cover method would involve multiple diversions to road and human traffic above ground, is dustier and noisier, and would have taken much longer.

With the new method, the underpass will be completed in "six to eight months", instead of "three to four years" with the cut-and-cover method -which involves excavating deep trenches along the entire stretch of the underpass.

The underpass is constructed under sections of Zion Road, Havelock Road and Ganges Avenue.

Mr Foo said: "It is hard for people to appreciate the benefits of this new method if we don't tell them about the long roundabout way pedestrians will have to walk if we had used the cut-and-cover, the several stages of road diversion, and the noise and dust residents in the nearby HDB blocks have to bear with."

Mr Foo said rectangular tunnel-boring machines are used extensively in China, where they are employed not only for underpasses but for underground roads too.

The unique machine - the first of its kind in Singapore - will be moved to the Thomson-East Coast Line's Stevens interchange station for another underpass that goes under the Bukit Timah canal.

In future, larger machines may be used to build MRT lines here. If so, such a machine would be able to bore a box tunnel large enough to accommodate two train tunnels as well as stations - significantly shortening the completion time of a new rail project and reducing disruption to the public.
