摘要
The present invention relates to a method and construction for constructing a non-unfired tunnel, and more particularly, to a method of constructing a non-unfired tunnel by using a guider, In case of inserting horizontal steel pipe, it is required to carry out steel pipe at the same time, but it is required to construct the steel pipe at the same time by fixing the deck steel to the side of the steel pipe adjacent to the horizontal steel pipe adjacent thereto. It is possible to maintain a constant gap between the steel pipes by inserting a horizontal gap material on the side of the horizontal steel pipe and by keeping the interval between the steel pipe upper part particles And a structure capable of supporting an upper load without leakage, In case of vertical indentation, pressurized deck steel is constructed as a unit, vertical spacing is used to adjust the height between steel pipes. And the steel pipe is press-fitted while longitudinal excavation is performed. In addition, for smooth construction of long-distance un-installation, the system is to be installed as a system that pushes forward the steel structure with the reaction force of the leading structure and post-press-in the structure at the gap. In order to prevent the subsidence in the soft ground, And the method of inserting the structure by repeatedly using the method of cutting the rock mass between the steel pipe and the steel pipe through the side opening of the steel pipe after the propelling of the steel pipe in the rock is repeatedly used to realize the unfolding method in the rock, Method is adopted to pull air forward so as to prevent roll-off bedrock settlement due to excavation and to reduce the traction force by using a roller-type moving device to reduce the friction at the bottom of the structure when the structure is towed In the construction method, Since the steel pipe and the deck steel are integrally joined to each other during the construction of the non-installation type tunnel, it is possible to achieve the first effect of reducing the air and the construction cost, It is possible to provide a second effect of realizing a shape in which a steel pipe and a steel pipe are attached so as to cope with a change in thickness of the upper slab, A third effect of arranging a horizontal spacing member as a distance adjusting device between horizontal steel pipes to cope with changes in the width of the structure, A fourth effect that a vertical spacing member, which is a height adjusting device, is disposed on the vertical steel pipe to cope with a change in the height of the structure, A fifth effect that can be applied to a non-unfolded tunnel in a pole section by reducing the frictional force by pre-pushing the steel pipe frame with the indentation, The sixth effect that the structure can be constructed while reinforcing the foundation so that the differential settlement does not occur in the soft ground, The seventh effect that the deck steel can be installed together while facilitating the steel pipe propulsion in the rock layer, The eighth effect that the air and the construction cost are reduced through the mechanical excavation when the steel pipe is propelled, As the ninth effect of reducing the friction force concentrated on the lower part of the structure through the roller type moving device on the foundation for towing the structure, it is possible to improve the simplicity and easiness of the tunnel construction and the efficiency of the work, The present invention relates to a method of constructing a non-opening tunnel using an easy pouring method of steel pipes and deck steels,
