Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further details.
As shown in Fig. 1,2,3,4,5, a kind of domatic building concrete layer landslide-proofing construction technology, including following construction step
Rapid:
(1), rock stratum perforate: offering anchor hole 2 on ground horizon d 1, anchor hole 2 is obliquely installed, and its angle is by domatic matrix 10
Domatic 14 determine, domatic 14 vertical with domatic matrix 10, the anchor hole degree of depth is 2-6m;
(2), arranging anchoring section: after anchor hole 2 is offered, put into multiple anchor cable 3 being connected to each other in anchor hole 2, anchor cable 3 stretches out
Anchor hole 2 port, puts into Grouting Pipe at anchor hole 2 end 50-100mm;
(3), anchoring section slip casting: after Grouting Pipe puts into anchor hole 2, inject concrete in anchor hole 2 by Grouting Pipe and carry out one
Secondary slip casting, until concreting is to anchor hole 2 port position, uses once grouting pipe 4, once grouting pipe 4 during once grouting
The mouth of pipe is in 50-100mm position below slurry all the time, and marginal not slurry limit is moved to anchor hole 2 port until detaching anchor hole 2,
Once grouting completes in 1h, and once grouting pressure is 5Mp;
(4), anchoring section slip casting is closely knit: after once grouting completes, the empty place producing anchor hole 2 inner concrete carries out secondary injection
Starching closely knit, use secondary grouting pipe 5 during secondary grouting, secondary grouting pipe 5 tube wall is offered injected hole, and is sealed injected hole
Stifled, secondary grouting pressure is 0.25Mp;
(5), pretension section is set: after secondary grouting completes, the anchor cable 6 of prestressing force rope 7 with anchor hole 2 port is fixed, in advance
Stress rope 7 uses before pouring and eliminates rust, and at its surface brush Colophonium, finally parcel Colophonium glass-fiber-fabric, the parcel number of plies is not
Less than two layers, place the sleeve pipe 8 allowing the anchor cable 6 stretched out to penetrate in anchor hole 2 port, in the socket of sleeve pipe 8 two ends, use butter
Filling, depth of cracking closure is 100-200mm, welds reinforcement 13 outside sleeve pipe 8 tube wall, and prestressing force rope 7 is through sleeve pipe 8 and extends
Outside sleeve pipe 8, sleeve pipe 8 and anchor hole 2 port are carried out encapsulation process, seal and use coarse cloth or sealing rubber ring;
(6), pouring domatic matrix: after pretension section is provided with, to carrying out concreting around sleeve pipe 8, concreting is arrived
At sleeve pipe 8 mouth of pipe, making and carry angled domatic matrix 10, domatic the 14 of domatic matrix 10 are vertically arranged with sleeve pipe 8;
(7), pretension anchoring: after domatic matrix 10 has poured, place prestressed slab 9, prestressing force rope 7 at sleeve pipe 8 mouth of pipe
Through prestressed slab 9, when the coagulation grade of the concrete at domatic matrix 10 is more than 80%, stretch-draw pretightning force rope 7 makes tension force
Reach 1.1-1.2N, stretch-draw 2 times, keep 15min every time, be offloaded to lock load, use anchor head 11 will be in pretightning force state
Prestressing force rope 7 be fixed on prestressed slab 9, anchor head 11 locking after, if be found to have obvious pretightning force loss be in lax
Time, stretch-draw should be compensated, if find pretightning force increment exceed design axle power 10% time, after should loosening again stretch-draw to turn down
Prestress value;
(8), closure: after pretension has anchored, exposed sleeve pipe 8, prestressed slab 9 and anchor head 11 outside concrete is mixed
Solidifying soil pours closure, and anchor head 11, before closure, uses rust cleaning, painting corrosion resistant coating to carry out antirust, during closure, bar-mat reinforcement is being placed above
Cover increases the bonding strength between domatic matrix 10, and reinforcing steel net cover thickness is not less than 50mm, the concrete closure at anchor head 11
Thickness is not less than 100mm, completes construction.
Although the detailed description of the invention of the present invention is described by above-mentioned combination, but not to scope
Limiting, one of ordinary skill in the art should be understood that, on the basis of technical scheme, those skilled in the art need not
Pay various amendments or deformation that creative work can make still within protection scope of the present invention.
