摘要： PURPOSE:To improve reinforcing effect by inserting a reinforcing member with the specified thickness into a drilled ditch formed by inserting a saw body into a bed rock, and thereby anchoring the base end of the reinforcing member onto a slope. CONSTITUTION:A saw body having numbers of drilling blades on its circumference is inserted into a bed rock while drilling the bed rock by each drilling blade so that a thin walled drilled ditch 40 is formed, which reaches the specified depth. Then, after the saw body has been pulled out, a reinforcing member 1 of a belt form which is 0.6-20mm in thickness, is inserted into the drilled ditch 40. Following which, grout G is injected between the reinforcing member 1 and the drilled ditch 40. In addition, an anchor plate 4 is arranged onto a protective wall 3, the base end of the reinforcing member 1 is extracted from the anchor plate, then, a wedge 5 is driven so that the reinforcing member 1 is anchored.

摘要： PURPOSE:To make anchorage of solid reinforcing material feasible by a method wherein a form is arranged on a threshold of an excavated groove, a blind cover is provided to an opening on the outside of the groove, the inside of the form is filled with filling agent, and a protection wall is formed to the surface of a natural ground except the place of the form. CONSTITUTION:An excavated groove 2 is formed and, at the same time, a belt-like reinforcing material 1 is inserted therein. A form 3 is placed on a threshold of the excavated groove 2, and a blind cover 6 is attached to the form 3. A grout hose 8 is inserted through an insert hole 10 provided to the blind cover 6, and filling agent such as grout is injected through the hose 8. Then a space around the belt-like reinforcing material 1 in the excavated groove 2 is filled therewith, and filling to the inside of the form 3 follows. After the filling is finished, the grout hose 8 is removed from the insert hole 10, and mortar 15 is sprayed to the natural ground surface Ms to construct a protection wall for the natural ground M. On spraying the mortar, the thickness of spraying is determined by using the outer edge of the form 3 as a ruler.

摘要： PURPOSE:To increase anchoring force with simplified structure by a method wherein holders of chucks are pulled outwardly by operation of a jacking means with a projecting part of a belt-like body held firm, and wedges are made to thrust deeply into insert holes. CONSTITUTION:A belt-like body 1 is fixed firm in a natural ground 2 and grout 4 is injected to places surrounding the belt-like body 1. After curing of the grout 4, a pressure bearing body 10 is provided to a protection wall 3, and the belt-like body 1 is temporarily fixed with wedges 12A, 12B inserted into insert holes 10a. And a press-in body 13A is placed on the wedges 12A, 12B, and jacks 15A, 15B and holders 14A, 14B are placed thereon. By turning clamping handles 18A, 18B, a space between the holders 14A, 14B is narrowed, and chuck pieces 16A, 16B are pressed against the opposite faces of the belt-like body 1, and thereby the belt-like body 1 is held tight. Then the hydraulic jacks 15A, 15B are extended and the wedges 12A, 12B are forcibly pressed into the insert holes 10a, thrusting the press-in body 13 toward the natural ground side. Thereby the belt-like body 1 is fixed firm to the pressure bearing body 10.

摘要： PURPOSE:To increase the load of an anchor, by making the width and thickness of an anchor-casting section larger than those of other sections, for construction of the form of slope. CONSTITUTION:Forms 4 are arranged on the face R of slope and are assembled in the shape of parallel crosses, so that the thickness H of an anchor-casting section 2 is larger than that h of other sections 1a, 1b. After that, at the central position of the casting section 2, a reinforcing pipe 5 is set; mortar 6 is cast in the forms 4 by a spraying method. Then, an anchor pit is board through to a deep section of the surface of sliding, and an anchor steel rod 3a is inserted into the pit and is fixed by injecting cement milk at the anchorage section. As a result, anchor yield strength can be economically obtained, and the applica tion range can be widened.
