Description

[Detailed description of the invention] This invention relates to a highly water-containing net-like material for use in improving the water retention capacity of the ground.

Highly water-containing resins (polymers) that can absorb several tens to hundreds of times their own weight in water are already known, and are used to improve water retention by spreading them on easily dry ground. Also, a rope-like rope made by wrapping such a high water content resin with a braid has recently been developed. Such highly water-containing ropes are often used in flowerpots and the like, but they are also often used to improve water retention in large areas such as farmlands and playgrounds. The purpose of this invention is to provide a rope with high water content that is easy to install over such a large area. Embodiments of this invention will be described in detail below with reference to the drawings.

Figure 1 shows fine granular high water content resin 1
This is a highly water-containing rope 2 formed by wrapping the rope with a braid. This rope usually has a diameter of 5 to 30 mm and a weight of several tens to several hundred grams per meter. As shown in FIG. 2, a plurality of such highly water-containing ropes are attached substantially parallel to a large net 3 to form a highly water-containing net A. In this case, the distance between the ropes is usually 20-100 cm. The material for the braid needs to be water-permeable and have a certain level of strength, and once it has been laid, it can get wet and tear in the rain, so cheap materials such as cotton or cellulose thread are preferable. Net 3 is usually made of synthetic fibers.
The size of one piece made from synthetic resin thread is several dozen or more.
A ^size of several hundred square meters is used. In the case of this embodiment, since the main purpose is to spread the rope evenly, the net does not need to be very strong, and the mesh may be coarse, ranging from several cm to 20 cm.

Of course, the rope can be attached to the net by tying it with thread or stapled, but it is most convenient to weave the rope into the net. In particular, since ropes made of braided cords are flexible, using a ratchet knitting machine makes it possible to weave the ropes simultaneously during the process of producing the net, which is efficient. In the string state, the highly water-containing polymer is an essential element and other materials, e.g.
Of course, fertilizers, seeds, soil improving materials, etc. may also be included at the same time.

Another embodiment of the invention is shown in FIG.
It is a highly water-containing net-like material especially for use in vegetation on slopes. Four or more chains of slow-release fertilizer formed into large particles weighing 10 to 30 g each wrapped in a water-permeable sheet material and connected in a chain, and two or more of the above-mentioned high water content ropes are placed at appropriate intervals. , usually attached to the net 3 in parallel. In this embodiment, since mud-like soil is sprayed onto the net or vegetation seeds are sprayed onto the net, a relatively fine-grained and strong net is suitable.
In addition, when used on slopes, even if it is not a net in the strict sense, it is generally a slope spread material made of water-permeable sheet-like materials such as wire mesh, locking material, straw, and non-woven fabric, which are laid down when there is vegetation. There is no problem.

Since it is technically difficult and troublesome to spread a small amount of highly water-containing polymer evenly over a large area of ground, the workability was greatly improved by forming it into a rope shape. In this invention, the ropes are evenly attached to the net-like material, so the highly water-containing polymer can be evenly distributed by simply laying the net on the ground. Since this type of highly water-containing resin can repeatedly absorb and release water, the use of the net-like material of this invention is suitable for use on ground that is prone to drying. In particular, if used together with a slow-release fertilizer that is effective for 2 to 3 years, it becomes an optimal vegetation material for slopes with poor vegetation conditions, such as bedrock.
