GEODETIC WORKS IN MICRO TUNNELING PROJECTS EXCAVATED BY PIPE-JACKING METHOD
Abstract
Installation techniques of pipes line, such as water, sewerage, gas etc. are changed nowadays. Because of conventional inst allation of pipes in trench has many disadvantages, such as disruption to traffic flow, loss of access, noise, additional safety and technical problems with other buried se rvices, trenchless pipeline technologies are used widely nowadays. Settlements of the road surface are not to be expected as well as road repair work is not necessary along the pipeline for trenchless installation. There have been considerable advances in trenchless pipeline installation techniques during the last decade. Pipe jacking, that is a method to install a pipeline section trenchless from the jacking shaft to the ta rget shaft, is one of these trenchless techniques. The problems caused by trench tec hniques and their associated costs can be reduced with pipe jacking method. Pipe jacking method can be used in micro tunnelling technology. Tunnel survey methods are also changed continuously depending on changes occured in tunnel excavation methods. As a result of considerable advances in tunnel survey methods, there is no need to make geodetic measurements in the tunnel. All geodetic measurements can performed out of the tu nnel automatically. Es pecially in micro tunnels, geodetic measurements can not performed in tunnel, because the size of it is not suitable to make measurements in tunnel. Because of the control of micro tunnel alignment is performed by computer suppo rted, accuracy of guiding of the tunnel machine has been increased horizontally and vertically. Because of increased work safety, accidents, that will be in tunnel excavation works, have been decreased to minimum level by the new techniques deve loped in tunnelling. Because of the automation in tunnel works, persons, who work in tunnel project, and the equipments, that are used in tunnel projec t have been decreased, as a result of this, economical advantages have been obtained.
