Abstract

PURPOSE:To make easier the delivery and storage of slope forms by a method in which an annular member consisting of a netting having a rigidity enough to stand by itself and a flexibility enough to be bent by manpower is joined in large numbers by stoppers in such a way as to make their compression and extention easier. CONSTITUTION:A large number of annular members 2 consisting of a material having large numbers of water-permeable holes 1 as well as a rigidity enough to stand by itself and a flexibility enough to be bent by manpower at least, e.g., plastic netting, etc., are arranged vertically and horizontally on a flat surface and then joined with one another at their contact points of the adjacent annular members by metal rings, metal stoppers, binding ropes, hot bonding, etc., to form a slope form. In layer the slope form, compressed annular members 2 are placed on a slope, extended vertically and horizontally, and fixed by anchor pins 5, and then the insides of the slope frames are embedded with soil.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a slope frame used for stabilizing soil on a slope, and is an improvement on the method disclosed in Japanese Patent Publication No. 16730/1983.

The framework according to the above-mentioned published patent No. 16730/1987 has very excellent features such as being able to be expanded on site and being able to construct a large area at once. Due to the manufacturing method, it is approximately rectangular. on the other hand.

The shape of the slope is not necessarily rectangular, but is often triangular or trapezoidal, and large slope frames are often cut and used (this creates waste and is problematic in terms of construction efficiency.

The present invention aims to correct these drawbacks and provide a legal framework that takes advantage of the conventional features as they are.

Embodiments of the invention will be described in detail with reference to the drawings.

As shown in Figure 1, a material with many water holes (L), such as a plastic net, has at least enough rigidity to stand on its own and is flexible enough to be bent without the need for large-scale machinery. Prepare a large number of annular bodies (2) consisting of metal rings (3), fasteners, binding strings, etc., and arrange them vertically and horizontally on a plane, and connect the adjacent annular bodies at their contact points using metal rings (3), fasteners, binding strings, etc. The frame is constructed by joining them using an appropriate method such as gluing or gluing.

The annular bodies constituting the legal frame of the present invention include meshes woven from plastic nets and monofilaments of synthetic fibers, wire meshes formed by weaving and welding flexible metal wires,
Exband metal.

It is made of materials such as bamboo, knitted fabrics made of bamboo bark, porous plastic, metal sheets, etc., and the material is not particularly specified, but it has the rigidity to at least be able to stand on its own when formed into a ring, and the ring can be compressed from the side to make it compact. In summary, it should be flexible enough to be expanded into a ring near the site, and waterproof and durable enough to maintain its strength in the soil for at least 2 to 3 years.

The method for forming the annular body may also be to form a ring in advance.

A sheet-like material may be formed into a ring by a method such as gluing, or, in the case of a woven fabric, it may be formed by placing the selvedge part on a border as shown in FIG.

As shown in FIG. 3, a plurality of annular bodies may be successively formed with ears.

The height of the toroid is usually 3-3Qcfn, preferably 5-2
051. The diameter is usually 10 cm to 2 m, preferably 20 to 1 m, and both the height and size are 0 m.It is common to use the same diameter1, but it is also possible to use different sized ones. .

When constructing the slope of the present invention, as shown in Figure 4, place the slope on the slope, pull it all the way in the vertical and horizontal directions, and fix it at appropriate points using anchor pins (5), etc. . Since the annular body is stretched, it usually deforms into a substantially diamond shape. In this way, soil is applied to the inside of the annular bodies and also to the gap P1161 formed in a substantially diamond shape between the annular bodies.

Since the present invention is configured as described above, it has the following features.

(1) As shown in Figure 5, the frame can be compressed to make it compact, making it easy to transport and store.

■ It can cover a large area at once, and construction is quick because it only needs to be expanded on site.

■ Because it is porous, excess water does not accumulate inside the soil.

Native plants become one with each other.

(4) As shown in Figure 6, a legal frame of any shape such as a triangle or trapezoid can be easily formed by juxtaposing the annular bodies.

In addition, the shape of the rectangular frame can be easily changed by removing the connectors, and the removed annular body can be used elsewhere, so there is no waste.

In the case of JP-A No. 56-16730, it is difficult to manufacture the deformed frame, and when deforming it on-site, the main body of the material must be cut, which requires a lot of labor, and it is difficult to reuse the cut material. It is.

Claims (1)

[Claims] Arrange a plurality of annular bodies with a large number of water holes, such as a plastic net, that is rigid enough to stand on its own and flexible enough to be bent by hand, and connect the adjacent annular bodies to each other at their contact points using a fastener, etc. as appropriate. A legal frame characterized by being constructed so that it can be compressed and expanded by being joined using materials and methods.
