Abstract

PURPOSE:To save materials and to enhance the workability by developing nonwoven fabric sheet having staggering cut yarns, over a slope surface, and by deforming the cut yarns so as to form deformed apertures which are then used for a tree-planting multiplying process, a forming process or a retaining wall forming process. CONSTITUTION:A nonwoven fabric sheet 1 having staggering cut yarns 2 having a substantially equal length, is fixed to the ground surface or a slope surface with fittings 3 or the like. In this case, the cut yarns 2 are expanded so as to form deformed apertures 4 having various shapes, and strips 5 defining the apertures 4 are made to rise up. In the case of a tree-planting multiplying process, seeds are set in the holes. In the case of a retaining wall forming process, blocks are laid in a conventional procedure with the use of the sheet 1 as a back filling material. Further, in the case of a forming process, the cut yarns 2 are maximumly expanded so as to form the apertures 4 having a maximum size, and the strips 5 are used as forms. With this arrangement, a field job is simplified so as to shorten the construction period and the number of members to be worked can be reduced, and further, it is possible to facilitate the maintenance and management of the members to be worked.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to, for example, a slope greening mulching method, a method frame method, a retaining wall method, etc. by effectively utilizing a non-woven sheet having a zigzag cut wound in a roll. Non-woven sheet construction method most suitable for construction of various construction methods.

[0002]

2. Description of the Related Art Conventionally, in the slope vegetative mulching method, seeds are planted on the slope by a seed spraying method, or means for preventing seed outflow and collapse are laid, and then seeds (seedlings) are planted. The construction method is used, and the so-called on-site construction method is the mainstream.

In addition, in the method of frame method, method of retaining wall, etc., first, the slope is made almost uniform, and then a framework for stabilizing the backing material is formed.
After that, as a backfilling operation, chestnut-stuffing, earth-sand-stuffing, etc., are laid in order up to a predetermined site in the framework, and then mortar or a mixed material of mortar and sand is laid in the site, or mortar is installed. A construction method of sequentially laying blocks, method frame blocks, and other retaining wall constituent materials via a joint adhesive such as is adopted, and the so-called on-site construction method is predominant.

[0004]

In the slope vegetation mulching method, the method frame method, etc. detailed above, since they are on-site construction, the number of construction parts, the number of points increases, and the number of points increases, Problems such as complicated setup and management may be considered.

Further, since the multi-step work is carried out sequentially and while taking a curing time or the like, it is inevitable that the working period is prolonged.

Further, as mentioned above, since many working steps are required, a large number of personnel are required, and there is a problem in the lack of human resources today.

[0007]

SUMMARY OF THE INVENTION Therefore, the present invention has the following objects for the purpose of facilitating and simplifying on-site construction, reducing the number of construction members and accompanying transportation thereof. Adopted the configuration.

That is, the construction method of the non-woven fabric sheet which can be used in the various construction methods of the present invention is, for example, a slope greening mulching construction method, a frame construction method, or a retaining wall construction method. The non-woven sheet according to the present invention, which is provided with a large number of streaks having substantially the same length in a staggered manner, and at the construction site, the staggered cuts of the non-woven sheet are formed in a hexagonal shape, a tire shape, and a substantially oval shape. While laying on the ground surface etc. while deforming into a deformed through hole, then using the deformed through hole of the stretched non-woven sheet, greening mulching work, method frame work, holding of the various construction methods This structure is characterized by wall work and the like.

[0009]

Next, the operation (construction method) of the present invention will be described.

First, in the slope greening mulching method shown in FIGS. 3 to 5, a roll-wound non-woven sheet (hereinafter referred to simply as roll-wound non-woven fabric) provided with staggered cuts of substantially the same length. The sheet) is brought to the construction site, and its end face is fixed on the slope, for example, via a fastener (hereinafter, simply fixed).

Thereafter, while expanding the roll-wound non-woven sheet, its slits are expanded and stretched until a deformed through hole is formed,
The other end face is fixed on the slope, for example, via a stopper (hereinafter, simply fixed).

[0012] As a result, a ground surface for preventing disintegration or seed sowing, which is made of a non-woven sheet, is formed on the slope, and so the seed surface is sowed by various methods.

It is possible to previously incorporate seeds into the roll-shaped nonwoven fabric sheet.

Next, in the retaining wall construction method shown in FIGS. 6 and 7, a roll-wound non-woven sheet (in this case, the roll-wound non-woven sheet is ideally thick). The same operation as described above is performed to spread it on the slope, spread the cut strip of the roll-wound nonwoven sheet, and stretch it until it becomes a deformed through hole, and fix the other end face firmly. .

As a result, the backing material made of a non-woven sheet is laid on the slope, and thereafter, the blocks are laid one by one through substantially the same operation or procedure as the conventional one. Of course, this backing material can be used as a drain.

In another greening mulching method shown in FIGS. 8 to 9, the roll-wound non-woven sheet is spread and laid in the same manner as in FIGS. 3 to 5, and then tree planting or natural wind masonry is applied. You can create a feeling of greening and natural retaining walls.

Although not shown, in the frame method, when a roll-wound non-woven sheet (thick one is preferable, as described above) is spread on the slope, the cut is expanded to the maximum extent. do it,
This is a construction method in which the largest deformed through hole is used and the band body forming this modified through hole is used as a frame.
