South-to-North Water Diversion Project - Hutuohe Inverted Siphon

In 2004,Sanbo contracted to undertake the Fully Automatic Hydraulic Liner Trolley for Hutuohe Inverted Siphon Project of the South-to-North Water Diversion Project-one of the state’s key projects. Hutuohe Inverted Siphon Project is situated in Zhengding County,Hebei Province,which is the first project to be kicked off in the Jing-Shi Section of the South-to-North Water Diversion Emergency Water Supply Project. The inverted siphon pipe adopts three-hole one-connection reinforcement concrete box type construction. Project use of the liner trolley has proven that fully automatic hydraulic liner trolley is featured by good grouting quality,quick formwork installation and removal,good results,easy operation and high degree of safety and reliabilty. Use of this product has overcome shortcomings of traditional formwork grouting,thus bringing about another major breakthrough and leap in concrete construction technology.

On October 22th,2006, the first concrete casting gets a successful performance on the jobsite of ShiTai(Shijiazhuang-Tai yuan) intercity passenger special line (contractor: Bureau No.22, CRCC). The MSS entire hydraulic inner form used on this project was made by SANBO.

For the time being, the inner form of MSS is usually formed by segmentations at home and abroad. It is the first time that moving in and out the form as a whole on a 32m-long beam in the world. The MSS, on a finished pier, can perform a piece of beam casting through a series of working procedures .The processes goes as follows: template adjustment -- reinforced lashing -- concrete pouring -- curing -- inner form removing--tensioning--outer form removing.

It is light in weight, full-hydraulic synchronizer in control, reliable in system characters, well-driven by synchronizer, reasonable in structure. It works automatically by hydraulic system. The effect of the concrete after removing the form is quite good. It can save 30% of time.
