Description
Technical field:
The utility model relates to a kind of ground anchorage anchor cable, particularly a kind of Pile plate anchorage cable.
Background technology:
At present at geotechnical anchor engineering---in the construction of side slope of backfilled roadbed supported reinforcing technique, the pressure that adopt are concentrated or pulling force concentrated earth anchor construction more, widely used is pulling force concentrated anchor cable, by the stake plated construction with sloping body with the backfill integral fastening, whole steel strand of anchor cable all pass backfill and are anchored on the backfilled roadbed supported stake plated construction of supporting, the stake plate is stressed big, thereby, stake plate cross sectional dimensions is big, it is many to pass steel strand, and because the difference of backfill and geotechnical body physico-mechanical properties, with the backfill integral fastening, sloping body is stressed unreasonable with stake with sloping body, two parts discontinuity is unfavorable for the permanent anchoring of a plate and anchor cable; In addition because slurry tensile strength is low, during stretch-draw, slurry tensile stress occurs and concentrates at the interface on anchoring section, and under the excessive action of pulling stress, crackle can appear in the injecting paste material of this part, thereby make slurry lose antiseptic effect to anchor cable, along with stretching force increases, progressive failure appears easily, and then the slurry tensile failure, and progressively move down, entirely ineffective until anchoring.
Technology contents:
The technical problems to be solved in the utility model is: solve that the stake plate bears that active force is big, size big and the problem of stake plate and sloping body discontinuity, constructional difficulties, anchoring effect difference, provide a kind of and make that stress distribution is more even, the transmission of power more is tending towards rationally, anchor cable structure simply, pressure dispersing anchorage cable---the Pile plate anchorage cable of easy construction.
The solution of the utility model is: adopt the pressure dispersing anchorage cable with two outer anchor heads, with side slope and backfill anchoring respectively; In the construction, adopt and divide three stretch-draw, locking.
Its concrete technical scheme is:
A kind of Pile plate anchorage cable, comprise outer anchor head, free section, anchoring section, outer anchor head is by intermediate plate, anchor slab, backing plate constitutes, be with inner support frame on the non-bending steel cable of anchoring section, outer support frame, there is guiding cap on the top of longest steel strand, be distributed with a plurality of supporting bodies on the described anchoring section, each supporting body is by non-bending steel cable and be enclosed within loaded plate on the non-bending steel cable successively, elastomeric pad, extruded sleeve is formed, be drilled with through hole and an injected hole of equating with the required number that passes steel strand on each loaded plate, do not wait by the non-bending steel cable number on each loaded plate, every non-bending steel cable end exceeds loaded plate and partly peels off to the bonding steel strand are arranged, it is characterized in that: this anchor cable has a plate anchor head A and two outer anchor heads of sloping body anchor head C, all steel strand all pass sloping body anchor head and constitute anchoring section, a part of steel strand are anchored on the plate anchor head A, a part of steel strand are anchored on the sloping body anchor head C, the number of the supporting body that links to each other by the outer anchor head of steel strand and each can equate, can not wait yet, the supporting body that links to each other with stake plate anchor head has m, the supporting body that links to each other with sloping body anchor head has n, both additions add up to m+n, in the formula: 1≤m≤4,1≤n≤10, n 〉=m, 2≤m+n≤12.
The steel strand number that passes on the loaded plate of each outer anchor head anchor slab and each supporting body does not wait, on the anchor slab of stake plate anchor head A at least 2, be at least 4 on the body anchor head C anchor slab of slope, on the loaded plate of the supporting body of top at least 2, increase progressively successively by 2 or 3 multiple from the top to sloping body anchor head C, on the loaded plate of the supporting body of the most close sloping body anchor head C on the number of steel strand and the sloping body anchor head C anchor slab number of steel strand consistent, be generally 4～36.
Because adopt said structure, the Pile plate anchorage cable of the utility model is compared with existing Pile plate anchorage cable, has the following advantages:
1, stressed mechanism is more reasonable: the root load of the Pile plate anchorage cable of the utility model is big, obviously diminishes near aperture direction load, helps the sloping body of instability is anchored at earth formation deep, makes full use of effective anchoring section, shortens the length of anchor cable greatly; Owing to the slurry segmentation pressurized of anchor cable, can greatly utilize the bearing capacity of the soil body, under same geological conditions, can provide bigger anchored force.
Each root anchor cable of the utility model is all used a part of steel strand anchoring slope body, a part of steel strand anchoring cantilever pile, like this, just make the stressed clear and definite, reasonable of sloping body and stake, greatly improve the stressing conditions of stake, help the long-term stability of sloping body and stake, and can reduce the sectional dimension of a plate, reduce the steel strand consumption.
2, stress distribution is more even, anchoring effect is better;
As previously mentioned, the Pile plate anchorage cable of the utility model has the stressed mechanism of pressure dispersing type, and this mechanism is by two or more supporting bodies and have the bond-anchorage section to produce, and each supporting body is made up of loaded plate, elastomeric pad, extruded sleeve and steel strand.When applying stretching force with the jack pair non-bending steel cable, steel strand are passed to slurry with load with the form of compressive stress by extruded sleeve, elastomeric pad, loaded plate, last slurry acts on the soil body (rock mass) in the shear stress mode, like this, load is disperseed and be evenly distributed in the anchoring body by loaded plate, slurry is not destroyed, anchoring effect is good.
3, guarantee the anchor cable life-span, be applicable to permanent protection.Because pressure disperses, slurry can not crack, favorable anti-corrosion effect, has adopted the non-bending steel cable that is with high density polyethylene (HDPE) again simultaneously, has formed multilayer proofing, has played the effect of permanent protection.
4, can shorten anchor cable length.Because stress distribution is even, has given full play to the geotechnical body supporting capacity, thereby can shorten anchor cable length, reduces cost.
Below, in conjunction with the accompanying drawings and embodiments, the architectural feature of the pressure dispersing type Pile plate anchorage cable of the utility model is further described.
