Gu, thus overcoming the deficiencies in the prior art.
The technical solution of the utility model is realized in：
A kind of anchor structure of rock side slope of the present utility model is that this structure includes rock side slope, the table of rock side slope
There is soft layer in face；It is provided with the anchor caverns along rock side slope length direction arrangement, anchor caverns run through through working tunnel in rock side slope
Soft layer leads to outside rock side slope；The inwall of anchor caverns is provided with a series of anchor holes, and anchoring in the hole is provided with two-ended cables；To wearing
Anchor cable two ends are provided with anchored end.
In aforementioned structure, described two-ended cables include a branch of steel strand wires, a branch of steel strand wires midfeather be provided with isolating frame,
The part that anchor hole is exposed at two-ended cables two ends is provided with anchored end, and the part that two-ended cables are located at anchor hole has poured binding agent.
In aforementioned structure, described anchored end includes being located at the positioning pipe in anchor hole aperture, is provided with flange outside positioning pipe；Turn over
Side is provided with connecting bolt, and connecting bolt is connected with the anchor plate on work anchor, and work anchor is through intermediate plate and the steel through work anchor
Twisted wire is fixedly connected.
Due to employing technique scheme, compared with prior art, this utility model can be in anchor cable position for this utility model
One end setting anchored end in anchor caverns, improves the pulling force of anchor cable by anchored end.Have that easy to maintenance, fraction is high, pre-
The advantage that stress loss is less, anchor cable length is short.Anchor caverns and working tunnel can double as scupper, effectively reduce slope underground water
Bit line, and quickly drain and infiltrate rainwater.This utility model is particularly adapted to the rock side slope administered using anchor cable.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is two-ended cables structural representation.
In figure is labeled as：1- rock side slope, 2- soft layer, 3- anchor caverns, 4- working tunnel, 5- two-ended cables, 6- anchoring
End, the former phreatic line of 7-, 8- improve after phreatic line, 9- anchor hole, 10- steel strand wires, 11- isolating frame, 12- binding agent,
13- positioning pipe, 14- flange, 15- connecting bolt, 16- work anchor, 17- anchor plate, 18- intermediate plate.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, but not as new to this practicality
Any restriction of type.
This utility model is constructed by the anchoring process according to a kind of following rock side slopes, as described in Figure 1：The method
It is that a series of working tunnel extending within rock side slope are beaten on rock side slope, then open to both sides in the bottom of working tunnel
Dig the anchor caverns extending along length of slope direction；Then beat a series of between the soft layer of anchor caverns and rock side slope outer surface
Anchor hole, and in anchoring in the hole, two-ended cables are installed, two-ended cables two ends are respectively provided with anchored end；By two-ended cables two ends
Anchored end improves the pulling force of two-ended cables.A series of described anchor hole is in fan-shaped distribution in vertical direction, and anchoring in the hole has poured
Binding agent, the quantity of anchor hole not can exceed that limited number in the range of anchor caverns rock mass ultimate bearing capacity.In described working tunnel
High outer low outward-dipping i=0.003～0.005；Anchor caverns and the highly minimum two ends in working tunnel junction are to intermediate, inclined i=
0.003～0.005；Anchor caverns and working tunnel double as scupper, infiltrate rainwater for quickly draining, and effectively reduce side slope underground
Waterline.Excavating in described side slope has at least one working tunnel, and each working tunnel bottom has all been excavated along length of slope side
To anchor caverns；The quantity of working tunnel depends on length and the height of side slope.
The anchor structure of the of the present utility model a kind of rock side slope constituting as stated above, as depicted in figs. 1 and 2, should
Structure includes rock side slope 1, and there is soft layer 2 on the surface of rock side slope 1；It is provided with rock side slope 1 along rock side slope 1 length direction
The anchor caverns 3 of arrangement, anchor caverns 3 run through soft layer 2 through working tunnel 4 and lead to outside rock side slope 1；Set on the inwall of anchor caverns 3
There are a series of anchor holes 9, in anchor hole 9, be provided with two-ended cables 5；Two-ended cables 5 two ends are provided with anchored end 6.Described two-ended cables 5
As shown in Fig. 2 including a branch of steel strand wires 10, a branch of steel strand wires 10 midfeather be provided with isolating frame 11, two-ended cables 5 two ends are revealed
The part going out anchor hole 9 is provided with anchored end 6, and the part that two-ended cables 5 are located at anchor hole 9 has poured binding agent 12.Described anchoring
