Abstract
The utility model discloses a strengthening net for active protection and control of debris flow. The strengthening net comprises a loose solid stacking layer penetrating the earth surface, anchor cables deeply fixed in a stiff ground layer, a net body covered on the anchor cables and anchor cable piers positioned on the net body and fixing the net body and the anchor cables together, wherein the net body adopts an up-and-down double-layer structure, and comprises a cable net in the upper layer and an ecological layer in the lower layer; and the ecological net is made from a completely biodegradable material and grass seeds are mixed in the ecological net. According to the utility model, the anchor cables are deeply fixed in the stiff ground layer, can not move and are covered with the net body; the net body is fixed together with the anchor cables through the anchor cable piers to form a permanent coverage area; a certain pre-tightening pressure can be exerted on substances in the coverage area to fix the substances in the primary position; and the net body adopts the up-and-down double-layer structure, the cable net in the upper layer mainly plays roles of stopping and locking substances in a source area and the ecological net in the lower layer mainly improves the properties of the loose solid stacking layer.
Description
Technical field
The utility model relates to the Geotechnical Engineering field, relates in particular to a kind of mud-rock flow and initiatively protects the improvement reinforcing network.
Background technology
Mud-rock flow is that mountain area cheuch or mountain region are domatic upper, is excited soil, water, the gas mixed flow between sediment laden flow and the landslide that contain a large amount of silt stones by water sources such as heavy rain, ice dissolutions.The formation of your strength must possess following three conditions simultaneously, and the suitable landform of the precipitous thing of being convenient to catchment is 1. arranged, and having to pile up on 2. has abundant bulk solids material, and sudden a large amount of flowing water source is 3. arranged in a short time.At present, mud-rock flow is a kind of global geological disaster, annual in frequently generation all over the world, and it is also very common in China, and in numerous geological disasters, mud-rock flow is considered to a kind of of lethality maximum, there is outburst suddenly, break with tremendous force, the characteristics such as rapidly, and have an avalanche, the double action that landslide and flood destroy, endanger larger, at present, the method of the source area of mud-rock flow being protected by protective screening is arranged, although this method can play certain Intercepting effects, and can eliminate an essential condition---the bulk solids material of debris flow formation, but eliminate not thorough, poor effect, can not improve the present situation of bulk solids material layer.
Summary of the invention
The purpose of this utility model just is that providing a kind of addresses the above problem, can be in the source area of mud-rock flow, and locking bulk solids material layer, and the mud-rock flow that improves the loose proterties of bulk solids material initiatively protects the improvement reinforcing network.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of mud-rock flow initiatively protects the improvement reinforcing network, comprise through earth's surface bulk solids accumulation horizon, deeply be fixed on anchor cable in firm hard formation, cover the dictyosome on anchor cable, be positioned on dictyosome the anchor cable pier that dictyosome and anchor cable are fixed together, described dictyosome is the Dual-layer structure, be respectively the steel rope net on upper strata and the ecological net of lower floor, described ecological net adopts the material of complete biodegradable to make, and is mixed with grass-seed in ecological net.
As preferably: described steel rope net adopts anticorrosion wire rope to work out.
As preferably: the mesh of described ecological net is less than the mesh of steel rope net.
Compared with prior art, the utility model has the advantage of: anchor cable is through earth's surface bulk solids accumulation horizon, deeply be fixed in firm hard formation, can not move, and be coated with dictyosome on it, and dictyosome is fixed together by anchor cable pier and anchor cable, formed fixing overlay area, the source area that this zone is mud-rock flow, can form to the material in this overlay area certain preload pressure, material is fixed up in situ, prevent that it from moving, even under the condition suddenly increased at heavy rain or current, water can flow away by the mesh of dictyosome, but can not take away the material under the dictyosome covering, in addition, dictyosome is the Dual-layer structure, the steel rope net on upper strata mainly rises and stops, the effect of locking source area material, and the ecological net of lower floor mainly improves the proterties of bulk solids accumulation horizon, be mixed with grass-seed in ecological net, after a period of time, grass-seed roots on the bulk solids accumulation horizon, can effectively improve the proterties of bulk solids accumulation horizon, avoid soil erosion, better protecting effect.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The structural representation that Fig. 2 is dictyosome in Fig. 1.
In figure: 1, source area; 2, bulk solids accumulation horizon; 3, firm hard formation; 4, anchor cable; 5, anchor cable pier; 6, dictyosome; 61, steel rope net; 62, ecological net.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1: referring to Fig. 1, Fig. 2, a kind of mud-rock flow initiatively protects the improvement reinforcing network, comprise through earth's surface bulk solids accumulation horizon 2, deeply be fixed on the anchor cable 4 in firm hard formation 3, cover the dictyosome 6 on anchor cable 4, be positioned on dictyosome 6 the anchor cable pier 5 that dictyosome 6 and anchor cable 4 are fixed together, described dictyosome 6 is the Dual-layer structure, be respectively the steel rope net 61 on upper strata and the ecological net 62 of lower floor, described ecological net 62 adopts the material of complete biodegradable to make, and be mixed with grass-seed in ecological net 62, described steel rope net 61 adopts anticorrosion wire rope to work out, the mesh of described ecological net 62 is less than the mesh of steel rope net 61.
Compared with prior art, the utility model has the advantage of: anchor cable 4 is through earth's surface bulk solids accumulation horizon 2, deeply be fixed in firm hard formation 3, can not move, and be coated with dictyosome 6 on it, and dictyosome 6 is fixed together by anchor cable pier 5 and anchor cable 4, formed fixing overlay area, the source area 1 that this zone is mud-rock flow, can form to the material in this overlay area certain preload pressure, material is fixed up in situ, prevent that it from moving, even under the condition suddenly increased at heavy rain or current, water can flow away by the mesh of dictyosome 6, but can not take away the material under dictyosome 6 coverings, in addition, dictyosome 6 is the Dual-layer structure, main the rising of steel rope net 61 on upper strata stops, the effect of locking source area 1 material, and the ecological net 62 of lower floor mainly improves the proterties of bulk solids accumulation horizon 2, be mixed with grass-seed in ecological net 62, after a period of time, grass-seed roots on bulk solids accumulation horizon 2, can effectively improve the proterties of bulk solids accumulation horizon 2, avoid soil erosion, better protecting effect.
