In order to ensure to reinforce anchor pole 31 pairs of rock matter slope bodies 11 reinforcement effect well, the diameter range reinforcing anchor pole 31 is 30-35mm, to ensure that reinforcing anchor pole 31 has enough intensity.The length range reinforcing anchor pole 31 is generally 2.5-3m, and is fixed in rock matter slope body 11, and its one end only needs the length range stretched out outside this rock matter slope body 11 to be 10-20cm, convenient fixing active protecting net 32; Ensure that reinforcing anchor pole 31 is fixed to rock matter slope body 11 part and has enough degree of depth, play rock matter slope body 11 reinforcement effect well.
In order to ensure the application life of reinforcing anchor pole 31, prevent its corrosion, reinforce on anchor pole 31 and be coated with zinc layers, namely this reinforcing anchor pole 31 is galvanized anchor rod.Certainly, conveniently active protecting net 32 is fixed on and reinforces on anchor pole 31, reinforce on one end that anchor pole 31 stretches out rock matter slope body 11 and can external screw thread be set.
In addition, in order to make the reinforcement effect that reinforcing anchor pole 31 pairs of rock matter slope bodies 11 are good, then on rock matter slope body 11, install reinforcing anchor pole 31 needs suitable density, reinforces anchor pole 31 density and arranges overstocked, can increase difficulty of construction and cost.Generally level interval 2.5-3.5m, and vertical interval 2-2.5m arrange one reinforce anchor pole 31 comparatively suitable, namely two reinforcing anchor poles 31 that level is adjacent are at a distance of 2.5-3.5m, reinforce anchor pole 31 at a distance of 2-2.5m for vertically adjacent two, both can ensure rock matter slope body 11 intensity, can ensure again difficulty of construction and cost lower.In order to make active protecting net 32 better be paved with corresponding rock matter slope body 11, need respectively at the bottom of the Po Ding and slope of each rock matter slope body 11 to fix a row and reinforce anchor pole 31.
In general domatic 111 areas of the rock matter slope body 11 of gentle slope belt 1 at different levels are larger, and protective screening generally makes relative narrower, thus, in order to be paved with active protecting net 32 on rock matter slopes at different levels body 11, generally that polylith protective screening is overlapped, be paved with rock matter slope body 11, the active protecting net 32 namely on every one-level gentle slope belt 1 is overlapped by polylith protective screening and forms.And protective screening is generally relatively long, thus for ensureing the intensity of active protecting net 32, every block protective screening is laid from top to bottom along this gentle slope belt 1.
The lap width scope of adjacent two pieces of protective screenings is 10-15cm, and its overlapping regions is fixedly linked by wire rope 33 is interspersed from top to bottom; Namely use steel cable 33, at overlap these two pieces of protective screenings interspersed from top to bottom of adjacent two pieces of protective screenings, thus the protective screenings that two pieces overlap mutually are fixed up.And use steel cable 33 to carry out interspersed connection two pieces of protective screenings, the intensity connected can be ensured, this protective screening can also be held by wire rope 33, and then strengthen bonding strength and the stability of whole active protecting net 32.The diameter range of wire rope 33 is 10-12mm, through ensureing that wire rope 33 has enough intensity, ensures that wire rope 33 can conveniently intert fixing simultaneously.Certainly in order to fixedly secure active protecting net 32 further, iron wire line or steel wire can also be used, at portion, the wire gauze 22 of active protecting net 32 with supporting component 2 is fixedly linked, this connected mode, also active protecting net 32 can be made to fix and support wire gauze 22, increase the steadiness of wire gauze 22.Active protecting net 32 can random selecting with the link position of wire gauze 22.
The steel wire diameter scope of protective screening is 3-4mm, and the sizing grid scope of protective screening is 50*50mm-70*70mm, to ensure that protective screening has sufficient intensity, thus is combined with reinforcing anchor pole 31 and reinforces rock matter slope body 11 and grow basic unit 5.
In addition, reinforce on anchor pole 31 in order to active protecting net 32 is securely fixed in, wire rope 33 can also be set and laterally intert each protective screening (i.e. wire rope 33 level intert each protective screening), and wire rope 33 is fixed on reinforcing anchor pole 31, reinforce on anchor pole 31 to ensure that protective screening is securely fixed in.Protective screening adopts high-tensile steel wires grid, after carrying out longitudinally (i.e. the above-below direction of wire rope 33 along domatic 111) through wire rope 33, laterally linking, being fixed on rock matter slope body 11 by reinforcing anchor pole 31, forming engineering protection, to prevent and treat all kinds of slope geological.And be that main active protecting net 32 carries out domatic 111 covered protections by wire rope 33 net or high-tensile steel wires grid, rock mass structure easily loose, broken, the scar weathering of high precipitous rock slope can be solved, cause the geological disaster such as falling rocks, landslide, and a difficult problem for system anchor bolt anchoring Hou Pen Quan bank protection cannot be carried out.
In like manner, because domatic 111 areas of the rock matter slope body 11 of gentle slope belt 1 at different levels are larger, and wire gauze 22 generally makes relative narrower, in order to be paved with wire gauze 22 on rock matter slopes at different levels body 11, generally that wire gauze 22 is overlapped, be paved with rock matter slope body 11, the wire gauze 22 namely on every one-level gentle slope belt 1 is overlapped by polylith and forms.And wire gauze 22 is general relatively long, thus for ensureing the intensity of wire gauze 22, every block wire gauze 22 is laid from top to bottom along this gentle slope belt 1.The overlap of adjacent two pieces of wire gauze 22 is bundled by iron wire line and is fixedly linked.The lap width scope of adjacent two pieces of wire gauze 22 is generally 10-20cm, and iron wire line can choose the iron wire that diameter is 1.2mm, to reduce difficulty of construction and cost, ensures the bonding strength of wire gauze 22 simultaneously.In order to increase the application life of wire gauze 22, prevent wire gauze 22 corrosion, wire gauze 22 can use galvanized wire mesh 22.
The iron wire diameter range of wire gauze 22 is 2.8-3.5mm, and the sizing grid scope of wire gauze 22 is 50*50mm-70*70mm, plants the carded sliver 4 to ensure that wire gauze 22 has sufficient intensity to support.
