Design and Construction of the Circular Shape Shaft Using the Reverse Construction Method
* Corresponding author: tangzq1974@sina.com
Restricted by the environment and the city’s planning, some pipe jacking used for the HV cable tunnel have to pass through some roads which has been build. Different kind of equipment has certain applicability in the pipe jacking construction procedure, especially with the geological condition, and encountering in the boulder is a common problem in the residual soil or in the strong weathered rock stratum, in this situation, a vertical shaft is needed to remove the boulder. In order to save the site area, a new shaft which is in circular shape is designed, and this paper introduces the main procedure of how to design and construct the new circular shaft. In a Fuzhou HV cable tunnel, the new shape shaft clears away the stone in the clay successfully, and reduces the impact on the ground traffic, the design and construction procedure of the new shaft have been analyzed in this paper, which provides reference for similar construction.
