Description
Technical field
The present invention relates to Geotechnical Engineering fields, are specifically related to a kind of Slope Treatment side using adit formula to anchor
Case.
Background technique
Anchor cable refer in suspension bridge it is lateral opening main push-towing rope is anchored when, by main push-towing rope be divided into many stock steel beams difference anchors in
In anchor ingot, these steel beams are just referred to as anchor cable.Anchor cable is that slope surface is fixed on by outer end, and the other end is anchored within sliding surface
The prestress wire that slope sliding face is passed through in rock mass stability, directly generates sliding resistance on sliding surface, increases antiskid friction
Resistance makes structural plane be in impaction state, to improve the globality of slope rock mass, to fundamentally improve the mechanical property of rock mass
Can, the displacement of rock mass is efficiently controlled, its stabilization is promoted, achievees the purpose that renovate concordant, landslide and crag, danger stone.
But anchor cable is usually since anchored end country rock relaxation destruction, Anchor Agent aging, anchored end stress concentrate gradual break
The reasons such as bad, anchor cable creep relaxation cause failure of cable, and then induce slope problem.It is now novel in order to avoid the above problem
Pressure dispersing anchorage cable, pressure anchor wire etc., its purpose is to guarantee the reliability of anchored end and actual effect.
Summary of the invention
In view of the above problems, the present invention provides a kind of using adit formula to the treatment schemes of anchor.
The technical scheme is that it is a kind of using adit formula to the treatment schemes of anchor, comprising the following steps:
Step 1: slope geological exploration
The slope geological to need reinforcement is surveyed, processing scheme is formulated by slope geological parameter, draws engineering drawing
Paper；
Step 2: anchor caverns are set
The anchor caverns of specified quantity are set into side slope in the two sides designated position of side slope according to engineering drawing, pass through longitude and latitude
Instrument is according to the anchoring hole site on engineering drawing on side slope surface, the position of anchor caverns inner marker anchor hole；
Step 3: anchor hole and two-ended cables are set
Mark position using drilling machine in slope surface anchor hole is drilled with anchoring to the anchor caverns internal labeling position of identical label
Anchor cable is worn in hole in anchor hole after punching, the anchor cable one end for exposing slope surface is fixed in slope surface with outer anchorage head, by anchor caverns
Interior anchor cable end is fixed with interior anchorage head, applies certain pulling force to anchor cable both ends, then blocks outer anchorage head, interior anchorage head；
Step 4: reinforcing bar connection
The outer anchorage head being arranged on side slope surface is interconnected using reinforcing bar and is fixed, by the interior anchoring in same anchor caverns
Head is connected with reinforcing bar；
Step 5: drainage hole is set
It pushes up to anchor caverns top and equidistantly sets three drainage holes in vertical anchor caverns hole.
Further, the processing scheme includes the need reinforcement area of side slope, the quantity of anchor caverns and position and anchoring
The quantity in hole and position.
Further, the anchor hole label same numbers number of interconnection is compiled same numbers in the step 2
Number anchor hole label get through and be formed anchor hole, digital number is convenient for construction identification.
Further, Fast Setting Cement Slurry, perfusion speed will be perfused in the step 3 after the block of anchor cable both ends into anchor hole
Condensate cement mortar avoids leak in anchor hole that anchor hole is caused to collapse.
Further, connecting the connection type of outer anchorage head with reinforcing bar in the step 4 is to intersect latticed connection, is handed over
It is more firm to pitch grid type connection.
Further, the bottom surface of the anchor caverns is the slope surface shape that two sides are low, centre is high, convenient for the row of water in anchor caverns
Out.
Further, the bottom end of the drainage hole is equipped with barrier net, and the barrier net can will fall off in drainage hole
Sundries barrier, avoiding drainage hole from largely falling off causes to collapse.
The beneficial effects of the present invention are: it is provided by the invention it is a kind of using adit formula to the treatment schemes of anchor, compare
For the prior art, first the slope geological to need reinforcement is surveyed, processing scheme system is carried out according to specific geological conditions
It is fixed, anchor caverns then are set in side slope two sides, the anchor hole label same numbers number of interconnection numbers same numbers
Anchor hole label get through and be formed anchor hole, Fast Setting Cement Slurry will be perfused into anchor hole after the block of anchor cable both ends, be perfused
Accelerated cement mortar avoids leak in anchor hole that anchor hole is caused to collapse, the outer anchorage head being arranged on side slope surface using reinforcing bar
Intersect latticed interconnection to fix, set drainage hole vertically upward in anchor caverns, at the same the bottom surface of anchor caverns be two sides it is low,
Intermediate high slope surface shape, convenient for the discharge of water in anchor caverns.In short, the present invention has, scheme is perfect, construction is convenient, highly-safe
The advantages that.
Detailed description of the invention
Fig. 1 is side slope sectional view of the invention.
Wherein, the outer anchorage head of 1- side slope, 2- anchor caverns, 3- anchor hole, 4- anchor cable, 5-, anchorage head, 7- reinforcing bar, 8- in 6-
Drainage hole.
