METHOD FOR NON EXCAVATED EXCAVATING CONSTRUCTION USING STEEL PIPE AND STEEL PIPE WITH HOLE

摘要

The present invention relates to a non-excavation method using the drilling steel and yugonggwan, press fitting at a predetermined interval in the ground The operation by which the press-yugonggwan obliquely upward between a large steel pipe after the grouting over the longer yugonggwan sheets by drilling unit drilling the inside after forming the hypothesis loop and placing the wall between the large steel tubes to make room to form a lining You can easily and shorten the construction period, and if great through the girder and slab to form a structure to provide a non-excavation excavation method using a steel pipe and yugonggwan that can be excavated inside. ; The purpose Large steel press fitting step of press fitting a large number of steel the present invention in the width direction and the height of the space to be excavated for achieving; Towards the formation of a large steel pipe steel pipe inside the neighboring press-fitted into the indentation direction along the width direction upward at a slope of a large steel pipe pushing the number of yugonggwan then the grouting between the internal yugonggwan by large steel pipe to penetrate the grout material into the surrounding yugonggwan hypothesis hypothesis that the loop forming step of forming a loop; After the hypothesis of a loop between the large steel pipe was excavated by a certain depth, while the lower reinforcing the bottom of the loop, forming a hypothesis lining and forward them to the hypothesis loop iterations performed by lining up the indentation depth of forming large steel pipe; Press-fitting a plurality of yugonggwan inclined outwardly toward the formation of a large steel pipe steel pipe inside the neighboring two sides of a large steel pipe is press-fitted into the vertical direction at a predetermined interval, and the grout material is as close to the grouting yugonggwan through the interior of yugonggwan hypothesis wall forming step such that the height direction is formed on both sides in the hypothesis wall between the large steel pipes by allowing penetration; The hypothesis was digging through the wall at a predetermined depth between a hypothesis and then while reinforcing walls and large steel pipe to form a lining and enforce them repeatedly to form hypotheses advanced to the indentation depth of the wall lining of the large steel pipe stage; Coupling the hypothesis underlying loop and placing a large steel pipe press-fitted in the width direction and the height direction through the space between the excavation wall, and installing the slab in the girder being connected to the girder structure to form a side-end in the ground; Be made to the technical subject matter, including the steps of digging a digging inside the great surface structure.
