摘要

The present invention is a perforated hole excavated with an excavation bit to supplement and prevent slope collapse for each slope (slope) due to cutting of the soil, cutting of rocky slopes, and prevention of natural slope landslides in civil engineering and building construction By inserting and installing the wire or nail body, one end is connected to the fixed anchor, and the other end is fixedly coupled to the acupressure plate provided on the slope surface to apply a tensile force, so that the acupressure plate can prevent sliding of the slope, and at the same time, the fixed anchor A pair of expansion and fixation wedge members are drawn out to face each other to the outer periphery of the fixed anchor so as not to be separated from the perforation hole and to be firmly coupled, and a stranded wire such as a wire is fixed and fastened to a portion drilled from the bottom surface of the perforation hole to a predetermined position. In addition to preventing the fixed anchor from being separated from the drilling hole even under the tension of the nail body, the fixed anchor is combined on various ground surfaces such as slopes or slopes to prevent soft ground or slope collapse, and to maximize the ease of vegetation and drainage on the ground. It relates to a multi-purpose fixed anchor for slope protection using a multi-hole bit that also considers the environment, aesthetics and other eco-friendly aspects, and a construction method using the same, The specific solution of the present invention is, "In the state in which the drilling hole H is formed by drilling and narrowing the slope using the excavation bit 10, the fixed anchor 20 inserted and fixed in the drilling hole H is inserted long in the center A groove 201 is formed, and a long hole-shaped cut-out 202 is formed in the longitudinal direction opposite to a predetermined position on the outer peripheral surface near the lower end, and the incision hole 202 is formed at a predetermined position on the outer peripheral surface near the lower end where the incision hole 202 is not perforated. A cylindrical housing 200 in which a pin hole 203 is perforated to face each other so that the pin P can be inserted therethrough; a sliding hole 212 is perforated in the center so that the expansion fixing rod 211 can slide through the sliding hole 212 A fixing member 210 fixedly coupled to one side of the wire 213 on all four sides of the outer circumferential surface of the ball 212; a spring 220 having an elastic force at a lower portion of the fixing member 210; a lower portion of the spring 220 in the center A sliding member 230 in which a through hole 231 is perforated so that the expansion fixing rod 211 can slide therethrough, and a lower portion of the sliding member 230 through the cutout 202 to the outside of the housing 200 Includes a pair of expansion and retention wedge members 240 that can be extended and drawn out; an expansion spring 250 provided between the pair of expansion and fixing wedge members 240 to enable expansion of the expansion and fixing wedge members 240; A multi-purpose fixed anchor for slope protection using a multi-hole bit, Drilling holes (H) with an excavation bit (10) to supplement and prevent slope collapse for each slope (slope) due to cutting of the soil, cutting of rock slopes, and prevention of natural slope landslides in civil engineering and building construction ) when excavating the drilling hole excavation step (S10) of forming an expansion perforation by a certain length upward from the bottom surface of the perforation hole (H), and in the center, the expansion fixing rod 211 is a sliding hole 212 A through hole provided in the sliding member 230 at the lower portion of the sliding hole 212 after passing through the center of the spring 220 to the lower portion of the fixing member 210 to which the wire 213 is fixedly coupled to the four sides of the sliding hole 212 . After passing through the expansion fixing rod 211 to 231, the coupling bars 251 of the expansion spring 250 are respectively fastened to the coupling grooves 242 respectively formed in the pair of expansion fixing wedge members 240 to match each other. And when the circular shape of the expansion spring 250 is fastened and coupled to the groove 244 of the expansion fixing wedge member 240 and the pair of expansion fixing wedge members 240 are matched, the semi-circular groove 241 is matched and the perfect circle groove Insertion step (S20) of inserting the fixed anchor 20 formed by fastening the expansion fixing rod 211 to the groove of the round circle and inserting it into the insertion groove 201 of the housing 200 into the drilling hole (H) (S20) ), and when the fixing anchor 20 reaches the bottom surface expansion perforation of the drilling hole (H), pull the expansion fixing rod 211 upward from the ground and the semi-circular groove 241 coincides with the round shape formed When the expansion fixing rod 211 is withdrawn from the groove, the expansion fixing wedge member 240 is rotated and expanded through the cut-out hole 202 of the housing 200 at the same time so that the fixing anchor 20 is inserted into the perforation hole (H). Anchor fixing step (S30) to fix it to the bottom surface drilling hole, and a wire tensioning step (S40) of pulling the wire 213 from the ground and fixing it to the acupressure plate (S) while maintaining the tensile force (S40), and the acupressure plate Fixing the wire 213 fixed to (S), but fixing the block plate (B), which is easy to drain and vegetation, to the outer periphery of the acupressure plate (S) using a fixing nut. As a structural feature of "a construction method using a multi-purpose slope protection fixed anchor using a multi-hole bit including a block plate fixing step (S50)", The present invention configured as described above compensates for and prevents slope collapse for each slope (slope) due to cutting of the soil, cutting of rock slope, and prevention of natural slope landslides in civil engineering and building construction. It is eco-friendly and can prevent the collapse of slopes or soft ground by forming and combining various block plates to further solidify and maximize the ease of vegetation or drainage on the ground surface. In addition, drill using an excavation bit capable of drilling, but after relatively drilling the bottom surface of the drilling hole, insert and install a fixed anchor into the drilling hole to connect one end of the wire or nail body to the fixed anchor, and the other end to the slope surface. A pair of expansion and fixed wedge members are opposed to the outer periphery of the fixed anchor so that the acupressure plate can be fixedly coupled to the provided acupressure plate and applied to a tensile force to prevent the sliding of the slope, and at the same time, the fixed anchor is firmly coupled without being separated from the drilled hole. To prevent the sliding of the slope by preventing the fixed anchor from being separated from the drilling hole even with a tensile force of a strand or nail body such as a wire by fixing and fastening it to the part drilled from the bottom surface of the drilling hole to a predetermined position, It has the effect of improving the slope load resistance and binding tension of the ground and maintaining strong tensile force even after a lot of time has passed after construction. have
