As protection of cut ground (cut ground) such as reservoirs,
Concrete construction framing, concrete retaining wall construction, mortar spraying, machin block masonry, etc. are performed, but the concrete surface exposed on the surface is hard, so plants can not extend the root part In addition, vegetation has not been carried out because water retention is low and sufficient water is not supplied to plants. For this reason, a concrete surface that turns from white to gray remains in the surrounding natural environment, giving an inorganic impression. In addition, when the cut slope is clay soil or bedrock, it may be left as it is without being covered with concrete or mortar, etc. It was not suitable for vegetation. The landfill site was not suitable for vegetation because it was easy to dry because there was no underground water vein when a park or road was created, and watering work was required during the dry season and maintenance was complicated.

However, the conventional water retaining material has the following problems. The water retention material made of a porous material such as urethane resin and sponge as described in 1) has a problem that the water absorption amount is small because water can be absorbed only in the holes, and the water retained at one end is easily lost. Was. Since the water retention material of 2) is filled only in the pores of the porous concrete, it has a problem that it is difficult to secure a sufficient water retention amount.
Just storing the water-absorbing polymer of the water retention material in the cylindrical bag body in 3) has a problem that the water-absorbing polymer is gradually biased and the bag body is easily deformed and lacks durability. .
The sandbag containing the water-absorbing polymer of the water retention material and the soil as in 4) can be vegetated only at the sandbag portion. Therefore, if the sandbag does not cover the entire surface of the low water retention slope such as the concrete surface, There was a problem that the slope of that part remained without vegetation. 5) The water-absorbing polymer of the water retention material is particularly susceptible to ultraviolet rays when it contains water, and is gradually decomposed and scattered, resulting in a loss of water retention ability, resulting in insufficient vegetation. . The water-absorbing polymer tends to decrease its water retention capacity as the temperature rises, so on a slope where the soil temperature rises to 50 ° C or more during the daytime in summer, sufficient water cannot be supplied to the plants and vegetation cannot be performed. There was a problem that.

The above-mentioned conventional slope greening structure and slope greening method have the following problems. When a water retention material made of a porous material such as urethane resin and sponge 1) is used, water retained at one end of the water retention material becomes underground water and easily flows away, and sufficient water retention power cannot be obtained, and vegetation is not obtained. There was a problem that the amount of water supply to the substrate was limited. In 2), the concrete itself is made porous, and the concrete strength tends to decrease.
It has to be reinforced with aramid chips, etc., which increases the production cost, and it is difficult to increase the diameter of the holes, so that the vegetated plants cannot grow thick roots and the growth tends to be poor. Had a point.
Laying a net or a mat as in 3) gives an artificial impression, and thus has a problem of giving a sense of incongruity with the surrounding natural environment. In addition, since the part where the plant can extend the root is limited to the part of the water retention material containing the water-absorbing polymer or the like in the bag, it is not possible to grow the flower whose root grows large or the shrub such as azalea or azalea. There was a problem that. When the sandbag is disposed on the low water-retentive slope as in 4), there is a problem that unevenness occurs and vegetation can be vegetated only in the sandbag portion, so that the vegetation becomes sparse. When the slope of the slope is large, there is a problem that sandbags are likely to slip off or deform from the slope and stable vegetation cannot be performed for a long period of time. When the water-absorbent polymer of the water retention material is mixed with the soil as in 5), it is difficult to mix uniformly because the specific gravity of the soil and the water retention material is greatly different, and the distribution in the vegetation base is poor. There was a problem of uniformity. In addition, the part where the water-absorbing polymer is biased absorbs a large amount of water, and when the root of the plant comes into contact with the water-retaining material, the root rots. Water is deprived, and sufficient water is not supplied to the root, and the plants die. Since the volume of the water-absorbent polymer expands significantly as it absorbs water, the water-absorbent polymer expands too much in the unevenly distributed portion, causing cracks and peeling of the vegetation base, resulting in poor durability.

According to this configuration, the following operation is provided in addition to the operation of the first aspect. a. The water absorption and water retention can be adjusted by appropriately selecting the water retention body, and the water supply can be adjusted appropriately by the difference in steam generation rate. Therefore, the optimum water supply can be adjusted according to the condition of the slope, vegetation base, vegetation, etc. Vegetation can be performed. b. When an inorganic porous material such as silica gel, alumina, zeolite, ceramics, and charcoal is used, there is no change in the shape due to the ingress and egress of water, so that the water-permeable container is excellent in durability without deformation. c. When an organic porous material such as foamed synthetic resin having continuous cells such as urethane foam, viscose foam, nylon foam, foamed phenolic resin, foamed urea resin, or sponge or cellulose is used, moisture can be quickly absorbed and discharged. d. When natural polymers such as starch, pectin, glucomannan, agar, carrageenan, algin, alginic acid and its derivatives, xanthan gum, guar gum, psyllium seed gum, etc. are used, handling is easy,
A large amount of water can be retained. e. In particular, when a water-absorbing polymer is used, it is possible to hold about 100 to 1500 times the volume of the dried volume, and a large amount of water can be secured with a small amount of the water-absorbing polymer. Further, even if the volume changes from water absorption-swelling and water discharge-shrinkage, the water-permeable container does not move inside because the movement preventing portion is formed, so that it is possible to prevent the shape of the laid water retaining material from being distorted. . f. Even if the water-absorbing polymer swells due to water absorption, the amount of water absorption is substantially the upper limit of the internal volume of the water-permeable container, so that it is possible to prevent the laid water retention material from absorbing excessive water. g. Furthermore, since the laid water retention material does not expand excessively, even if the vegetation base is formed on the upper surface, it is possible to prevent the vegetation base from being damaged or peeled off due to excessive force, and to prevent the water absorbing polymer from absorbing water and swelling. The influence on the vegetation base by the volume change of dehydration-shrinkage can be minimized.

Here, the shape of the water-absorbing polymer is not particularly limited, but those in the form of powder, particles, flakes, fibers and the like are preferably used. These may be stored in the water-permeable container as it is, and may be bonded to a sheet or the like forming the water-permeable container in advance with a water-resistant adhesive such as a cellulose-based, polyurethane-based, reactive acrylic-based, or rubber-based adhesive. Alternatively, a mixture of a water-absorbing polymer and an adhesive may be sprayed on a sheet or the like. The water-absorbing polymer is used in an amount of 0.02% to 5%, preferably 0.03% to 3%, more preferably 0.05% to 2% of the inner volume of the water-permeable container at the time of maximum expansion. Is done. As the amount of the water-absorbing polymer becomes less than 0.05%, even if it swells, it does not reach the maximum inner volume of the water-permeable container, and it tends to be impossible to secure a sufficient amount of water absorption. As the swollen water-absorbing polymer reaches the maximum internal volume of the water-permeable container before reaching its maximum water-absorbing capacity, the water-absorbing polymer does not run out and becomes wasted. When an excessive internal pressure is applied to the water-permeable container to absorb water, and a flexible water-permeable container is used, the deformation tends to be remarkable. Further, if the ratio is less than 0.03% or more than 3%, the above tendency becomes remarkable, and if the ratio is less than 0.02% or more than 5%, the above tendency becomes more remarkable.
