【正文】 ce to poor vulgar resistance, management, etc. pruning application conditions 22 Design stable soil and rock slope soil barren slope, especially the earthrock fill slope with mixed can play a solid earth prevent blunt and improve plant grass quality good effects. steel wire s active protection Through the anchor and support rope with a fixed pattern will cover the slope of steel wire mesh surface. For through the fixed mechanism in anchor or impose certain support line and gets the tension of steel wire s, as well as in used as weathered peel, slipped and fell flat or tiny particles, the protection of inhibiting when soil erosion diffused or with metallic s or spread to the whole slope and geogrid form a continuous support. The tension system gets homework clingy slope formed local soil should move or happen or the small displacement wrapped after orthotopic stuck to its near, thus realize the prestressed active protection function. The system function principle similar spray anchor bracing level protection system. But its flexible characteristics can make the system will local body around in to downslide evenly transfer of the whole system so as to give full play to defend ability, so that the system can bear larger downslide, at the same time it and threedimension vegetation as and plant supporting realize plant protection, make the plant roots hold the soil slope protection system function, to achieve the best massing of slope protection and environmental protection. steel wire s passive protection This method is a kind of can intercept and stockpiling rockfalls flexible block stone s, steel wire s, by fixed system, depression ring and steel column four parts. . Application conditions Rock mass slope surface interactive development, integrity is poor, has the fine may be high cutting slope. mechanism When rockfalls shock block stone, its impact of flexible to first via web abreaction, and the remaining load from the impact point to the rope system load, and eventually spread to neighboring cascade 23 bedrock and stratum, and anchoring bolt and by the final residual loads based bear to reach a small degree. 24 4 Comprehensive Protection rocky slope greening hydroseeder technology Greening hydroseeder technology, its core is in the rocky slope build a can let plant growth and planting matrix and not be scoured the porous stable structure. It USES special spray mixing machine will soil and fertilizer, anic matter, waterretaining material, plant seeds, cement mixing water sprayed into dry material after sheared off, because the bonding effect, the cement mixture can be in rock surface to form a layer of hardening body with continuous space. Some degree of sclerosis that grow from erosion, and within a seed, fill gaps of soil, water materials, filling in the gaps is planting matrix space, it is to plant roots growth space. application conditions Not only applicable to all the slope rock mass after excavation, but also for rock pile, soft rock, fractured rock, rock, extremely acidic soil medium and retaining wall, HuMianQiang rock slope, concrete structures such as the bad environment is unfavorable greening. construction method (1) trim slope In highway slope shoring slope engineering, pares level, typically require cleared surface sundry can. If there are very bump place must undertake handling. (2) the anchor, hang s First, then drilling in slope surface will machine woven s openbook pave hung on slope surface, reoccupy anchor or anchor nail fixed. For smaller ( 1:1) slope rock mass structure stability of the slope, already do, or the steep slope of the arch frame hang s, facing not directly spray mixing rockface good materials. (3) spray mixing Materials after mixing proportional using custom spray water and mix mechanical mixture sprayed into the PH slow granule rockface after. Injection points twice, first jet does not contain the seeds of mixture 7 ~ 25 8cm, spray, followed closely by the thickness of the second injection contains seeds, spray the mixture of 2 ~ 3cm. Spray thickness of mixed materials 10cm average thickness for 3 ~ 15cm, the variation. (4) cover But after the jets covering . fabric, careless, shade s, straw and prevent the rains washed out such moisturizing. (5) maintenance If not raining hydroseeder is required watering everyday keep moist soil. 7 days or so monly, a month, lawn or produce sod was lessened germinate two months coverage after more than 90%, and the lawn or produce sod was lessened, can reduce gradually watering frequency. frame space slope protection . 1the applicable condition: Weathering more serious rocky slope and slope stability of soil slope higher. out frame space form Frame space revetment can choose diamond frame space, hexagon frame space, masterslave frame case, etc structural requirements: (1) frame space inside plant grass, usually adopts borrow soil hydroseeder method or plant turf techniques. (2) the frame space forms square, lozenge, vaulted, main ribs with oblique cross rib or wavy horizontal rib and several geometry bination and other forms, frame space and cross rib wide ~ m, main ribs wide about 1m monly, frame space span ~ m. (3) should be based on the conditions set fixed pile or anchorage muscle fixed.
