摘要

1994年6月2日,Riva del Garda水电站的混凝土高度运输创下了新的世界纪录(532米)。该项目要求建造一个新的测压井和进水管道,并将现有的地面压力管道替换为一个新的地下压力管道,以减少对环境的影响。两条平行的隧道被挖掘:一条用于莱德罗-加尔达湖的位置,另一条用于运输管道的金属元素。通过用5000平方米的混凝土填充开挖墙和管道之间的环形空间,将自支撑金属管的所有长度(790米)都堵住了。为了减少对环境的影响,决定从厂房附近的下端和挖掘室泵送混凝土。记录高度:532米(垂直)和790米(总长度)远远超过1985年西班牙“ESTANGENTO SALLENTE”发电厂获得的前记录(432米)。

Concrete Pumping: A New World Record
New world record of altitude transportation of concrete (532 m) was reached on the 2nd of June 1994 in Riva del Garda Hydroelectric Power Plant. The requirement involved the construction of a new piezometric well and intake conduit and the replacing of the existing surface penstock with a new one built underground to reduce environmental impact. Two parallel tunnels were excavated: one for Ledro - Garda lakes location, the other for transporting penstock's metal elements. The self supporting metal pipe has been blocked for all its length (790 m) by filling of the ring space between the excavation wall and the piping with 5,000 m2 of concrete. In order to reduce environmental impact it was decided to pump concrete from the lower end from and excavated chamber near the Powerhouse. The record level: 532 m (vertical) and 790 m (total length) widely exceeded the former one (432 m) obtained in 1985 in Spanish "ESTANGENTO SALLENTE" Power Plant.
