摘要： PURPOSE:To prevent the slackening and falling of planting materials sprayed on the upper part of a water-impermeable slope by dividing the water-impermeable slope into contour lined sections by using horizontal cement mortar beams inserted with iron bars having a high bonding strength. CONSTITUTION:Fibrous composite mats 3 are laid in a contour lined manner on a water-impermeable slope 1 by means of concrete nails 4. Then, anchor bolts 5 are driven at equal intervals along the lower ends of the mats 3 in such a way that the heads of the anchor bolts 5 are exposed about 15cm or more from the mats 3. Then, the heads of the anchor bolts 5 are connected by iron bars 6 and on the upside of the part, drain pipes 7 are inserted at equal intervals into the mats 3. Then, cement mortar is sprayed on the drain pipes 7, the iron bars 6, and anchor bolts 5 in such a way as to cover all of them. And so, a planting material 10 consisting of soil, fertilizer, seeds, etc, is sprayed on the slope 1 divided by cross beams 2 on cotrour lines.

摘要： PURPOSE:To lessen the loss of a spraying material by a method in which anchor nails are pierced through a metal netting through a coil spring-like spacer provided underlying the metal netting and fixed to the ground, and then the thickness of the spraying material is controlled so that the metal netting is positioned at the intermediate level of the spraying material. CONSTITUTION:In fixing a metal netting 1 to a sloped land by anchor nails 2, the anchor nails 2 are driven into the ground 6 through a coil spring-like spacer 3 provided under-side of the metal netting 1, whereupon the metal netting 1 is lifted by the spring force of the coil spring-like spacer 3 and held down by the keyed portion of the head of the anchor nail 2 in such a way that the metal netting 1 is held at a given interval from the surface of the sloped surface 5.

摘要： PURPOSE:To provide the efficient forming of a proper sprayed soil thickness as well as to make a better growing of plant in the spraying of seeds on the face of slope by a method wherein an artifitial active soil is mixed in a mixture composed of seed, curing agent and fertilizer etc. and then they are sprayed on the face of slope. CONSTITUTION:Water, seed 3, curing agent such as wooden fiber etc. and fertilizer are fed in the agitating mixer of a hydroseeder spraying machine and at the same time, artificial active soil such as SOIL GOLD of 0.02-1kg for one liter of water, adhesion intensifying agent such as AQUA KEEP etc. of 1-10g for one liter of water is added and they are agitated, transmitted by a pump under their uniform slurry 2, they are sprayed by a nozzle on the face of slope to show a thickness of 0.5-2.0cm.
