Through the utility model provides a pair of prestressing force combined method highway high slope supporting construction, reinforcing bar protection network and the firm of side slope have been guaranteed and have been connected that the body of rod of stock forms the frictional force that has increased stock and soil for the heliciform, has further realized reinforcing bar protection network and the firm of side slope and has been connected to the setting up of stock, concrete placement makes the reinforcing bar protection network become permanent strutting from an interim protection shape of face on the reinforcing bar protection network.
Description
Technical field
This utility model relates to a kind of high slope rockmass technology, particularly a kind of prestressing combination method High Slope on Expressway supporting construction.
Background technology
Highway is in order to account for farmland, arable land less as far as possible now, can walk across Gu Jinshan, for mountain highway, and inevitable crossing-river tunnel, level off hilltops and cut slope, form cutting, the most more stable massif, through construction and excavation, easily cause the most more stable massif, through construction and excavation, rock mass is disturbed, internal stress disequilibrium, and stress once discharges, just Instability of Rock Body may be made to be deformed, lax, rubbing, extruding, fracture, causes falling rocks and landslide etc. to endanger.
Therefore, find a kind of effective measures to solve the slope retaining problem under massif side slope, sand gravel side slop's conditions, and ensure reliability and the economy of its supporting simultaneously, become those skilled in the art problem of extremely paying close attention to of row.
Utility model content
For solving the problem that existing massif side slope loss of stability is deformed causing falling rocks with landslide, this utility model provides a kind of prestressing combination method High Slope on Expressway supporting construction.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
A kind of prestressing combination method High Slope on Expressway supporting construction, including side slope, it is arranged at the reinforcing bar protection network on described side slope surface, described slope retaining structure also includes that the body of rod is formed as the anchor pole of spiral helicine column structure, described anchor pole one end is welded on described reinforcing bar protection network, and the other end of described anchor pole is inserted in inside described side slope；Described reinforcing bar protection network includes being enclosed by bar-mat reinforcement and sets the box body formed and be arranged at the building stones of described tray interior；Having poured concrete layer outside described reinforcing bar protection network, described concrete layer is provided with at least two rhones.
Preferably, described anchor pole is provided with and prolongs described rock-bolt length direction and be provided with at least two plasma discharge hole.
Preferably, the cross section of described side slope is formed as stepped.
Preferably, described anchor pole is many, is set in row along described side slope surface is longitudinally spaced.
Preferably, described concrete layer uses high flow load to make.
A kind of prestressing combination method High Slope on Expressway supporting construction provided by this utility model, the setting of anchor pole ensure that reinforcing bar protection network is connected with the firm of side slope, the body of rod of anchor pole is formed as helical form and increases the frictional force of anchor pole and soil, furthermore achieved that reinforcing bar protection network is connected with the firm of side slope；Concrete layer is cast on reinforcing bar protection network and makes reinforcing bar protection network be formed as permanent supporting from a provisional protection face.

Description of reference numerals: side slope 1, reinforcing bar protection network 2, anchor pole 3, concrete layer 4, box body 21, building stones 22, rhone 41.
Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, it is described in detail below in conjunction with the accompanying drawings and the specific embodiments.
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of prestressing combination method High Slope on Expressway supporting construction, including side slope 1, it is arranged at the reinforcing bar protection network 2 on described side slope 1 surface, described slope retaining structure also includes that the body of rod is formed as the anchor pole 3 of spiral helicine column structure, described anchor pole 3 one end is welded on described reinforcing bar protection network 2, and it is internal that the other end of described anchor pole 3 is inserted in described side slope 1；Described reinforcing bar protection network 2 includes being enclosed by bar-mat reinforcement and sets the box body 21 formed and be arranged at the building stones 22 within described box body 21；Described reinforcing bar protection network 2 is outside has poured concrete layer 4, and described concrete layer 4 is provided with at least two rhones 41.
The body of rod of anchor pole 3 be formed as spiral helicine purpose be strengthen anchor pole 3 grab ground effect, realize the bonding strength of reinforcing bar protection network 2 and side slope 1 soil by increasing with the frictional force of soil.Reinforcing bar protection network 2 is formed as rectangular structure, and what multiple reinforcing bar protection networks 2 were overlapped mutually is arranged in side slope 1.Rhone 41 extends to the bottom of concrete layer 4 from the top of concrete layer 4, and rhone 41 is for when sleety weather, and the water come by eminence stream, is avoided in the soil horizon that water penetrates within side slope 1 to road ditch venting by rhone 41 as far as possible.
A kind of prestressing combination method High Slope on Expressway supporting construction provided by this utility model, the setting of anchor pole 3 ensure that reinforcing bar protection network 2 is connected with the firm of side slope 1, the body of rod of anchor pole 3 is formed as helical form and increases the frictional force of anchor pole 3 and the soil within side slope 1, furthermore achieved that reinforcing bar protection network 2 is connected with the firm of side slope 1；Concrete layer 4 is cast on reinforcing bar protection network 2 and makes reinforcing bar protection network 2 be formed as permanent supporting from a provisional protection face.
Preferably, described anchor pole 3 is provided with and prolongs described anchor pole 3 length direction and be provided with at least two plasma discharge hole (not shown).
With reference to Fig. 1, it is preferable that the cross section of described side slope 1 is formed as stepped.The cross section of side slope 1 is formed as stair-stepping purpose and is to ensure when landslide phenomenon occurs in side slope 1, be positioned at the mountain stone of higher position, earth will not fall directly on highway, but buffered during dropping at the fast speed, avoid to the full extent and vehicular traffic is caused damage.
With reference to Fig. 1, it is preferable that described anchor pole 3 is many, longitudinally spaced it is set in row along described side slope 1 is domatic.
Preferably, described concrete layer 4 uses high flow load to make.Its performance also can rely on its deadweight to fill in block stone and template equably everywhere for the construction that is not added with vibrating, and need to use polycarboxylate high performance water-reducing agent.When construction, provisional protection body reinforcing bar protection network 2 directly pours high flow load and can form permanent support.
The above is preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
