The present invention relates to a tension-type Removable Nail and the construction process, firmly reinforced soil through fixation strength and stiffness caused by grouting due to mechanical friction and removes the nail bars as well as to reduce the cloth factories close construction is possible An object.
Tension-type expression removed four days according to the present invention, the inclined surface facing the rear portion (11) a fixing head (10) and formed; Type four days removal rod 20 to which the leading end is releasably connected to the fixing head and; The support tube (30) surrounding the removed four days type rod distal end coupled to the head and the fixing; And the support to the circumference of the pipe supporting pipe are installed through the extension is to allow sliding around squeezed additional fixed to the wall of underground four days of ball-packer; Is mounted so as to be expanded toward the wall of the four days the ball between the inclined portion of the fixing head circumference of the support tube of said jungle room earth is extended by the tension of the four days rod and the fixing head into the ground around the four days Ball inserted into the ground and is fixed by the fixing piece in a nail hole (1) on the ground, including the two or more that fixing the fixing piece (40).
Construction method of the tension-type expression removed four days according to the present invention, the first step of puncturing the nail hole (1) in the ground; A second step of inserting the Tensile scrubber formula nail (100) installed inside the perforated ball four days through the first step; And the third step of the second stage after removing the tension-type equation of the earth around the jungle room jungle room to expand the district to be part of the nail fixed to the wall of the compression ball four days; A fourth step of the first and through the step 3 Tensile the removal type four days rod of the tension-type Removable four days so that the fixing extend toward the wall surface of the moving ball the fixing piece four days the (40) by the said fixing head toward the ground Wow; And Step four days five and removing the removal-type rods removed from the fixing head to the exterior of support tube 30, four days of the tension-type expression removed; Characterized in that it comprises a sixth step of grouting the four days between the ball and the support tube.
