喷射混凝土:干喷还是湿喷?
Sprayed Concrete:Dry or Wet?
         为进入长期被忽视的德国市场,
MBT Woermaan地下工程公司以
“2000年隧道建设”为题召开了一次专
业会议,并展示了该公司提供的混凝土
喷射的产品和方法。通过展示干喷和混
喷的方法,对这两种系统的优缺点进行
了比较。
德国—采用湿喷少吗?
        MBT国际地下建筑工程公司总经理
汤姆-梅拜是湿喷法的积极拥护者。据
他介绍,在德国湿喷法和干喷法的比例
是20:80,在斯堪底那维亚和意大利湿
喷法则占100%,而在瑞士和法国湿喷法
和干喷法的比例是80:20。
        出售单个设备的时代已经过去,如
今隧道施工人员要求提供完整的解决方
案。最便宜的产品并不总是最经济的方
案,所需要的应当是符合技术要求的经
济的方案。
The MBT Woermann Untertagebautechnik GmbH
staged a special congress with demonstrations
of the products and methods it markets for
concrete spraying under the slogan Tunnelling
2000 upon entering the German market, a field,
which it had long neglected. As both the
dry-mix and wet-mix methods were offered, the
pros and cons of both systems were up for
comparison.
Germany-deficit in
Wet-Mix application?
Tom Melbye, director of MBT International
Underground Construction and an active
champion of the wet-mix method, quoted a
ratio for the wet-mix to dry-mix methods of
20:80 in Germany, whereas in Scandinavia and
Italy, wet-mix holds a 100% share, while in
Switzerland and France the ratio stands at
80:20 in favour of wet-mix.
The times when ponents were
sold are over, tunnellers expect global
solutions. The cheapest products do not
always lead to the most economic solution.
The target must be the economic solution for
