Description

The present invention relates to slope stabilizing structures.

On slopes where landslides are likely to occur, it is necessary to stabilize the slope by allowing soil to settle on the slope in advance. Conventionally, Patent Documents 1 and 2 have disclosed techniques for preventing slope collapse using a net.

Patent Document 1 describes a net that covers a slope, a cable routed between anchor members on the net, a restraining member disposed above the cable with the male threaded portion of the anchor member passing through, and a cable that is connected to the cable. A slope stabilizing structure is disclosed that includes a cable coupling member that couples to a restraining member, and a nut that is threaded onto a male thread to support the restraining member toward the cable. In the slope stabilizing structure of Patent Document 1, the cable is fixed to the lower surface of the main body of the restraint member by the cable coupling member, and the restraint member is applied bearing pressure toward the cable by a nut screwed into the male threaded part of the anchor member. As a result, the cable is held on the lower surface of the main body while being pressed upwardly by the cable coupling member and downwardly by the protrusion of the restraining member.

Patent Document 2 discloses a method that is composed of a base that is attached to a slope and a clamping frame, the base has one or more openings, and a rib that attaches the clamping frame, and a legal frame is configured between the pressure receiving plate and the clamping frame. A slope stabilizing structure is disclosed in which a porous band-like body is sandwiched and fixed at the center.

By the way, the net in Patent Document 1 and the porous strip in Patent Document 2 are flexible enough to follow the unevenness of the slope and are suitable for preventing slope surface erosion. Strength is not expected, and relatively low-strength materials such as rhombic wire mesh and resin nets with wire tensile strength of 290 to 540 N/mm ² are used.

In order to prevent the slope from collapsing (sliding), it is necessary to drive a plurality of anchor members into the slope and suppress (tighten) the slope using a bearing plate provided at the head of the anchor member. Furthermore, it is necessary to prevent local collapse of the slope that occurs between the anchor members, and when a net is used as a slope work installed on the slope surface, it is desired that the net has high strength and is difficult to deform.

However, in the technique disclosed in Patent Document 1, a flat plate-shaped restraining member is supported by a nut, and the net is fixed between the restraining member and the slope. In the case of such a fixing method, since the net is directly installed on the slope surface and fixed with a bearing plate, followability can be ensured to some extent. However, when the net is changed to a high-strength one to prevent local collapse, the net is difficult to deform and has no flexibility, so the bearing plate may float depending on the unevenness of the slope around the bearing plate, making it necessary to use the bearing plate. The tightening force may not be transmitted to the ground.

Similarly, in the fixing method according to the technology disclosed in Patent Document 2, since the porous strip is installed between the pressure receiving plate and the clamping frame, the porous strip is replaced with a high-strength net with less flexibility in order to prevent local collapse. If changed, there is a risk that the ability to follow the slope will deteriorate and the effect of preventing local collapse may not be sufficiently exerted.

The present invention has been made in view of the above circumstances, and its purpose is to provide a slope stabilizing structure that can suppress collapse of the entire slope and local collapse of the surface layer of the slope.

A slope stabilizing structure according to the present invention is a slope stabilizing structure installed on a slope to stabilize the slope, and includes a plurality of anchor members embedded in the ground of the slope, and the anchor members can penetrate. a lower bearing pressure member installed on the slope, in which a lower through hole is formed; and an upper support installed above the lower bearing pressure member, in which an upper through hole through which the anchor member can pass is formed. a pressure member; and a high-strength net disposed between the lower bearing pressure member and the upper bearing pressure member, which covers a region of the slope in which the plurality of anchor members are embedded, and the upper bearing pressure In the member, a first inclined surface is formed on the lower surface facing the high-strength net, and the first inclined surface is inclined so as to approach the slope toward the outside from the upper through-hole, and the high-strength net has a tensile strength of 550 N/. The lower bearing pressure member is a high-strength wire mesh made of wires with a diameter of mm ² or more, and the lower bearing pressure member has a flat lower surface, and a second sloped on the upper surface so as to approach the slope outward from the lower through hole. An inclined surface is formed, and the high-strength net is in contact with the first inclined surface and the second inclined surface .

According to the present invention, it is possible to suppress the collapse of the entire slope and the local collapse of the surface layer of the slope.

The high-strength net 7 is brought into contact with the first inclined surface 52 of the inclined plate section 54 and the extended surface 56 of the edge plate section 55.

Next, a method for constructing the slope stabilizing structure 1 according to the present embodiment will be described.

First, the embedded portion 21 of the anchor member 2 is embedded in the ground to a depth deeper than the sliding surface P between the moving layer 91 and the immobile layer 92 of the ground, and is fixed to the ground.

Then, the lower bearing pressure member 30 is placed on the anchor member 2 from above, the anchor member 2 is passed through the lower through hole 31, and the lower bearing pressure part 3 is installed on the slope 9. Then, the lower nut 4 is screwed onto the male threaded portion 22 of the anchor member 2, and the lower bearing pressure portion 3 is supported through the spherical washer 42.

The high-strength net 7 is then used to cover the region of the slope 9 where the plurality of anchor members 2 are embedded. At this time, the anchor member 2 is passed through the mesh of the high-strength net 7 and installed so that the high-strength net 7 does not move (slip) with respect to the slope 9.

Then, the upper bearing pressure member 50 is placed on the anchor member 2 from above, the anchor member 2 is passed through the upper through hole 51, and the upper bearing pressure part 5 is placed on the high strength net 7. Then, the upper nut 6 is screwed onto the male threaded portion 22 of the anchor member 2, and the upper bearing pressure portion 5 is pressed through the spherical washer 62. As a result, the high-strength net 7 is forcibly deformed along the first slope 52 and brought into contact with the slope 9.

FIG. 7 is a diagram for explaining the effects of the slope stabilizing structure 1 according to the embodiment. The entire slope of the ground having the slope 9 tends to collapse with the sliding surface P between the moving layer 91 and the immobile layer 92 of the ground as the boundary. Further, in the ground having the slope 9, the surface layer of the slope tends to collapse locally in the area between the plurality of anchor members 2, 2, with the sliding surface Q as the boundary.

According to the present embodiment, a plurality of anchor members 2 are embedded in the ground of the slope 9, and a lower bearing member 30 installed on the slope 9 has a lower through hole 31 through which the anchor members 2 can pass. , an upper bearing pressure member 50 installed above the lower bearing pressure member 30 in which an upper through hole 51 through which the anchor member 2 can pass is formed, and an area on the slope 9 in which a plurality of anchor members 2 are embedded. The upper bearing pressure member 50 has an upper through hole 51 on its lower surface facing the high strength net 7. A first inclined surface 52 is formed which is inclined toward the outer side and approaches the inclined surface 9, and the high-strength net 7 is brought into contact with the first inclined surface 52.

Thereby, the pull-out resistance force T1 due to the lower bearing pressure member 30 and the pull-out resistance force T2 due to the peripheral surface friction of the anchor member 2 can be applied to the ground of the slope 9. In addition, the high-strength net 7 is pressed by the upper bearing pressure member 50, and the pressed high-strength net 7 is deformed along the first inclined surface 52. Therefore, the bearing force Tp that supports the slope 9 by the high-strength net 7 can be applied to the region between the plurality of anchor members 2 , 2 . Therefore, it becomes possible to suppress the collapse of the entire slope with respect to the slip surface P.

In particular, the high-strength net 7 supported by the upper bearing pressure member 50 is forcibly deformed along the first slope 52 and comes into contact with the slope 9. This allows the high-strength net 7 to exert a bearing force Tp on the slope 9 in the region between the plurality of anchor members 2 , 2 . Therefore, it is possible to suppress local failure of the slope surface layer relative to the slip surface Q. Therefore, it is possible to suppress the collapse of the entire slope and the local collapse of the surface layer of the slope.

According to the present embodiment, the lower bearing pressure member 30 includes a lower nut 4 that is screwed onto the anchor member 2, and a lower bearing pressure part 3 that is supported by the lower nut 4 and in which the lower through hole 31 is formed. The upper bearing pressure member 50 includes an upper nut 6 that is screwed onto the anchor member 2, and an upper bearing pressure part 5 that is supported by the upper nut 6 and has an upper through hole 51 formed therein. have

Thereby, the fastening force of the lower nut 4 is transmitted to the lower bearing pressure part 3, and the pulling resistance force T1 by the lower bearing pressure part 3 and the pulling resistance force T2 due to the peripheral surface friction of the anchor member 2 are transferred to the ground of the slope 9. can be made to act. In addition, the fastening force of the upper nut 6 is transmitted to the upper bearing pressure part 5, the high strength net 7 is supported by the upper bearing pressure part 5, and the high strength net 7 subjected to the pressure is applied to the first inclined surface 52. deformed along the line. Therefore, the bearing force Tp that supports the slope 9 by the high-strength net 7 can be applied to the region between the plurality of anchor members 2 , 2 . Therefore, it becomes possible to suppress the collapse of the entire slope with respect to the slip surface P.

In particular, although the high-strength net 7 is composed of strands with a tensile strength of 550 N/mm ² or more and has low flexibility, by screwing the upper nut 6 into the male threaded portion 22, the high-strength net 7 can be It is forcibly deformed along the slope 52 and comes into contact with the slope 9. This allows the high-strength net 7 to exert a bearing force Tp on the slope 9 in the region between the plurality of anchor members 2 , 2 . Therefore, it is possible to suppress local failure of the slope surface layer relative to the slip surface Q.

The resistance force necessary to suppress the collapse of the entire slope can be borne mainly by the pull-out resistance force T1 and the pull-out resistance force T2 obtained by making the lower nut 4 bear the lower bearing pressure part 3. . Further, the resistance force necessary to suppress local collapse of the slope surface layer can be borne by the bearing force Tp obtained by mainly causing the upper nut 6 to bear the upper bearing pressure part 5. Therefore, it is possible to suppress the collapse of the entire slope and the local collapse of the surface layer of the slope.

According to this embodiment, the distance L1 from the upper through hole 51 to the tip 52b of the first inclined surface 52 is larger than the distance L2 from the lower through hole 31 to the outer edge 5c of the lower bearing pressure section 3. Thereby, the high-strength net 7 deformed along the first slope 52 can be brought into reliable contact with the slope 9. For this reason, in the area between the plurality of anchor members 2, 2, the bearing force Tp for bearing the slope 9 by the high-strength net 7 can be reliably applied. Therefore, it becomes possible to further suppress local failure of the slope surface layer with respect to the slip surface Q.

According to the present embodiment, the upper bearing pressure portion 5 is provided with an extended surface 56 extending along the slope 9 on the outer edge side of the first slope 52 . Thereby, the sharp portion of the outer edge 5c of the upper bearing pressure portion 5 can be prevented from coming into contact with the high-strength net 7, and the high-strength net 7 can be supported by the stretched surface 56. Therefore, it is possible to prevent the high-strength net 7 from being damaged by the sharp portion of the outer edge portion 5c of the upper bearing pressure portion 5.

According to this embodiment, the lower bearing pressure portion 3 has a second inclined surface 32 formed on the upper surface facing the high-strength net 7 so as to approach the inclined surface 9 toward the outside from the lower through hole 31. , the high-strength net 7 is brought into contact with the second inclined surface 32 . Thereby, the second inclined surface 32 can maintain the deformation of the high-strength net 7 that is pressed against the upper bearing pressure portion 5. For this reason, in the area between the plurality of anchor members 2, 2, the high-strength net 7 can more reliably apply the bearing force Tp against the slope 9.

According to this embodiment, the high-strength net 7 is a high-strength wire mesh made of strands with a tensile strength of 550 N/mm ² or more. Thereby, the bearing force exerted on the slope 9 by the high-strength net 7 can be sufficiently ensured. Therefore, in combination with the bearing force of the lower bearing pressure member 30, it becomes possible to suppress collapse of the entire slope and local collapse of the surface layer of the slope.
