PC The construction method and structure of non-excavation tunnel that extrudes pc structure into the steel pipe

摘要

[0001] The present invention relates to a method and a construction for a non-unfired tunnel, and more particularly, to a method for constructing a non-unfired tunnel using a large diameter, a small diameter, A construction method for propelling a deck frame so as to prevent an outflow of the earth particles to an interval between the steel pipes while preventing the steel pipe from being pushed forward in the method of propelling the steel pipe,A first effect that a tunnel can be constructed using only a steel pipe having a constant standard so that the demand of the type of the steel pipe required for the construction of the non-installation type tunnel, that is, the large diameter steel pipe and the small diameter steel pipe,Since the deck frame and the guide frame are used, not only the second effect of enabling coping with the change in the width and height of the tunnel,The third effect is that the number of steel pipes used is reduced by using deck molds,The fourth effect of eliminating the problem caused by the construction error of the steel pipe between the large-diameter steel pipes due to the absence of the large-diameter steel pipe,The fifth effect of eliminating the problem of displacement of the ground due to the lack of the upper surface soil due to not using the upper large-diameter steel pipe,It is possible to extract 3/4 of the press-fitted steel pipe pieces, so that it is possible to remarkably reduce the construction cost through reuse,A method of forming a tunnel structure by putting in the field so that a tunnel structure can be formed safely using a PC structure and a steel pipe is minimized and a method of forming a tunnel structure by a non-The present invention relates to a construction method and structure of a non-installation tunnel in which a PC structure is extruded into a steel pipe so that a total of seven places, such as air, construction cost, and aesthetic appearance, can be expected to be provided with simplicity and ease of construction and efficiency of operation.;
