Construction Technique of Self propelled Steel Trestle for Small Hydraulic Tunnel |
| |
| Abstract: | In view of problems of small hydraulic tunnel, such as small cross section, narrow construction site, complex construction process and interference problems, self propelled steel trestle is researched. The early stage strength of concrete is fully used to provide support for the trestle sole weight and traffic load. With the special flexible base and hydraulic pressure for control of track, the construction technique of self propelled steel trestle for small hydraulic tunnel has been explored. So, it solves the problems of excavation and lining construction with cross operation effectively. It has been used to construction of diversion tunnel with length of 22.377 km for Jiniu hydropower station, and guarantees the engineering quality and construction period, which can provide reference for similar projects. |
