Description
Technical field
Reinforced the present invention relates to Rock And Soil and support technology, more particularly to a kind of compound anchoring and its anchoring process.
Background technology
In decades, the prevention and controls and technology on landslide have obtained faster development, especially anchorage technology, and it is by burying
If anchor cable in the earth formation tightly locks together on stratum, in mine, water conservancy, water power, highway, railway, municipal administration, city
Build, the field such as geology, military project obtains extensive use, and key effect is played in national economy key project construction.But it is existing
The anchorage technology or anchor force that can be provided is limited, consolidation effect is not ideal enough, or cost is high, difficulty of construction is big, technique
Complicated the problems such as, serious restriction is constituted to the application of its further genralrlization.
The content of the invention
The technical problems to be solved by the invention, which are to provide one kind, can provide huge anchor force, improve anchoring effect, and
Cost is low, construction is easy, technique is simply combined anchoring.
Another technical problem to be solved by this invention is to provide the anchoring process of the compound anchoring.
To solve the above problems, a kind of compound anchoring of the present invention, it is characterised in that:It includes anchor cable body and pad
Platform, backing plate and anchor slab;The pad on the backing plate with being equipped with anchor cable hole;The top of the anchor cable body sequentially passes through the pad
The anchor cable hole of platform and the backing plate is connected together with the anchor slab;The anchor cable body bottom be stratiform ladder be distributed by
The Cable Structure of steel wire composition, the cylindric explosive of the water resistant equipped with detonator is accompanied between the outer layer and internal layer of every rank.
The length of each layer steel wire differs in the anchor cable body, and outer layer is short, internal layer length, central shaft are most long.
An injected hole is provided with the backing plate.
A kind of anchoring process of compound anchoring as described above, comprises the following steps:
(1) anchor hole is bored to rock and soil slope by design requirement;
(2) the explosive of the detonator is housed to the anchor cable body per arranging section between rank outer layer and internal layer;
(3) the anchor cable body that will be equipped with the explosive is placed in the anchor hole bottom hole;
(4) the slip casting into the anchor hole, makes the injecting cement paste bury the anchoring section of the anchor cable body completely, at once detonating charge;
(5) it is described after applying the pad at the opening of the anchor hole after injecting cement paste consolidation and allowing the anchor cable body top to pass through
Pad and the anchor cable hole at the backing plate center, and apply prestressing force and lock the anchor cable body on the anchor slab;
(6) it is suitable for reading to the injected hole to refilling the injecting cement paste in the anchor hole by the injected hole on the backing plate, together
When cast the injecting cement paste in wall-rock crack.
The present invention has advantages below compared with prior art:
1st, detonation driving anchor cable body scatters per the steel wire of rank outer layer to anchor hole wall and rock cranny in the present invention, drives slip casting
Body drives the part steel wire of anchor cable body to penetrate among Rock And Soil crack, and anchor cable body is anchored in anchor hole by injecting cement paste.
2nd, in the present invention after the cylindric explosive charge of water resistant, the different steel wire of length corresponding to anchor cable body different layers is built
Comprehensive, three-dimensional compound anchoring is played, the different steel wire of length is anchored, while providing anchor force, played a role respectively
And cooperate, make the whole anchoring section anchor hole of anchor hole with the shearing stress distribution on slip casting body interface than more uniform.
3rd, the present invention calls the ground in the range of whole anchoring section to greatest extent by the cooperation of the different steel wires of length
Layer intensity, and anchor force can be improved with the increase of the anchor cable body number of plies and length in theory, the security of engineering is obtained significantly
Enhancing.
4th, simple in construction, easy construction of the invention, with low cost, can significantly speed up project progress.
