Abstract

PURPOSE:To effectively perform the protection work of a slope by a method in which connecting members consisting of large numbers of concrete frames are set in a lattice form vetically and horizontally on a slope and then fixed with anchors. CONSTITUTION:A connecting member 5 is formed by connecting concrete frames 1 arranged in the longitudinal direction through the projected ends 3a of reinforcing wires 3. The connecting members 5 are set in plural rows along the vertical direction on the slope 6 while vertically hanging them through a rope passing through the through pipes 4 of the frames 1 by means of a crane, etc. Then, the connecting members 5 are set in plural rows along the horizontal direction on the slope 6 while hanging them horizontally by the crane so as to form a latticed body 7, and then the connecting members 5 are mutually crossed at the projected ends 3a of the reinforcing wires 3 and the crossing points are fixed to the slope 6 with anchors 8. Then, soil is placed on a metal netting 10 attached to the meshes of the latticed body 7 to form a banking and then young trees, etc., are planted on the banking.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a slope protection method used when constructing a slope protection device to be installed on a slope for the purpose of preventing slope collapse.

2. Description of the Related Art Slope protection devices are generally installed on steep slopes along roads to prevent them from collapsing. As one of this type of equipment, there is a device in which a large number of concrete frames are installed on a slope in a vertical and horizontal grid pattern, and the slope is maintained with these frames.

However, in the past, when constructing such equipment,
Each frame member is individually installed on the slope, and after the installation, the frame members are connected to each other, which has the disadvantage of poor workability and requiring a great deal of labor and time.

This invention was made with attention to these points, and its purpose is to connect the frame materials in advance, suspend the connected bodies, and install the grid on the slope in a vertical and horizontal grid pattern. The aim is to achieve efficient construction by doing so.

An embodiment of the present invention will be described below with reference to the drawings. The IFi frame material shown in Fig. 1 is made by installing a plurality of reinforcing wires 3 along the longitudinal direction and a plurality of insertion tubes 4 along the width direction in a concrete member 2 formed into a prismatic shape. Both ends Ja of the fist reinforcing wire 10 protrude from both ends of the concrete member 10, respectively. Compensation! [4
As the material 3, a normal steel wire, a steel wire, a PCH wire, or a PC steel wire is used.

The frame members 1 thus formed are arranged in sequence along the longitudinal direction as shown in FIG.
They are connected via the protruding end S1 of the material 3. That is, the frame members 1 are connected to each other by twisting the terminals Jm together, by hooking them together in a rib shape, or by connecting them to each other by using a shackle or the like. The connecting body 5 constructed by connecting the frame members 1 together in this way is
As shown in FIG. 3, a lobe is passed through one push-through pipe 4 of the frame member 1 disposed on one end side, and the connecting body 5 is vertically suspended by a crane force via this rogue a. The connecting body 5 is installed on the vertical axis 1ilrc along its longitudinal direction.

In this way, a plurality of rows of connecting bodies 5 are provided on the slope 6, each extending in the vertical direction of the slope 6. Next, as shown in FIG. 3, pass the low f & through the two insertion tubes 4 of the other connecting body 6, attach a chestnut, gouge b, etc. to the terminal side, and move the connecting body 5 with a crane etc. through the low go. The connected body 5 is installed horizontally on the slope 6 so as to be horizontally suspended.

Connecting bodies 5 are successively installed in the lateral direction of the slope 6 in a lattice pattern to form a lattice-like main body 7 as shown in FIG. The vertical and horizontal connecting bodies 5 intersect with each other at the terminal ends 3a of the reinforcing wire 3, and each of the intersecting parts is anchored to the p-slope by an anchor 8. Furthermore, if necessary, concrete, molten glast, or glue may be poured into each intersection to make the area brazed. In this case, corrosion of the terminal Ja of the reinforcing wire 3 can be prevented, and , has the advantage of being able to reinforce the intersection.

9. In the main body 7, wire mesh I is stretched vertically and horizontally through each insertion tube 4.
Qt-The above wire league and install it, and this wire mesh J
An embankment is placed on the surface of O, and seedlings, etc. are planted on this embankment.

In addition, when installing the connecting bodies 5t in the lateral direction of the slope 6, a number of connecting bodies 5 are suspended at the same time via four gangs, and they are arranged on the slope 6 all at once. Good too.

Furthermore, the frame material 1 is not limited to the case where reinforcing wires 3 are buried in a single concrete member 2, but also when a plurality of concrete members 2 are used as shown in Fig. 6, and the reinforcing wires 3 are buried between them. It may be configured as follows. Furthermore, the frame material has an appropriate notch on its side wall surface, and after installation on the rough surface, the earth retaining concrete panel, extract / motherboard / 4-nel, net-embedded panel for slope surface use is inserted through the notch. Or, by incorporating multiple darts, you can fix it after installing it on the slope. The wire mesh for contacting the slope surface may be locked through the bolt.

As explained above, according to the present invention, a plurality of frame members are connected by joining the protruding ends of the reinforcing wire rods, and the connected bodies are suspended and arranged in a vertical and horizontal lattice pattern on a slope. The reinforcing wires are intersected at their terminal ends, and each of these intersections is anchored to the slope via an anchor. Compared to the case where they are interconnected, workability is greatly improved and efficient construction can be achieved. In addition, each frame material has reinforcing wire embedded in it, which improves its strength and allows it to stably protect slopes over long periods of time.
