Description
Technical field
The utility model relates to Anchor Cable Technique field, especially a kind of Recyclable anchor rope.
Background technology
Along with the development of China's urban construction, deep-foundation pit engineering increases, and in deep-foundation pit engineering, usually use anchor cable to carry out temporary lining, but complete its steel strand rear of existing cable bolting are all not recyclable or the rate of recovery is low, cause great waste.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Recyclable anchor rope, can solve the problem that the anchor cable rate of recovery is low, and the rate of recovery is high and easy, greatly reduces construction cost.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of Recyclable anchor rope, comprises steel strand,
Steel strand are built in sleeve pipe, and steel strand one end is fixedly connected with fixed base, and the steel strand other end is connected with Recyclable anchor rope head;
In Recyclable anchor rope head, anchor cable casing inside is provided with elastic clip, elastic clip is socketed on steel strand, back-up block is positioned at anchor cable casing side, first spring one end is fixedly connected with back-up block, and the first spring other end is connected with briquetting, and flat head screw is arranged in anchor cable casing by the second spring, flat head screw is positioned on briquetting, and briquetting withstands the end of elastic clip.
Elastic clip is the cone of hollow, and the size of middle part circular hole matches with steel strand external diameter.
Leakproof oxidant layer is filled with in sleeve pipe.
A kind of Recyclable anchor rope that the utility model provides, steel strand are socketed on by elastic clip, briquetting withstands the end of elastic clip, and and spring, cooperation between flat head screw, make when slip casting completes and carries out stretch-draw, prestressing force is greater than insurance power, elastic clip produces compressive strain, under the effect of spring with pulling force, briquetting will come off, therefore when reclamation is performed, steel strand are made to produce slight vibrations, 3 elastic clips will come off, steel strand just can be extracted out, namely complete and reclaim anchor cable process, the problem that the anchor cable rate of recovery is low can be solved, the rate of recovery is high and easy, greatly reduce construction cost, the design being filled with leakproof oxidant layer in sleeve pipe can prevent steel strand from getting rusty, and guarantees that it is re-used after reclaiming.
Be example according to certain building site practice of construction project, amount to construction anchor cable 191, after adopting the utility model, reclaiming the steel strand that also secondary utilizes is 191, the Φ 15.2mm steel strand of depreciation process amount to 13503m, the heavy 1.102kg of every linear meter(lin.m.), amounts to 14.88T, can save construction cost 140,000 yuan altogether.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model Recyclable anchor rope head.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of Recyclable anchor rope, comprises steel strand 3,
Steel strand 3 are built in sleeve pipe 2, and steel strand 3 one end is fixedly connected with fixed base 4, and steel strand 3 other end is connected with Recyclable anchor rope head 1;
In Recyclable anchor rope head 1, anchor cable casing 1-1 inside is provided with elastic clip 1-2, elastic clip 1-2 is socketed on steel strand 3, back-up block 1-3 is positioned at anchor cable casing 1-1 side, first spring 1-4 one end is fixedly connected with back-up block 1-3, and the first spring 1-4 other end is connected with briquetting 1-5, and flat head screw 1-6 is arranged in anchor cable casing 1-1 by the second spring 1-7, flat head screw 1-6 is positioned on briquetting 1-5, and briquetting 1-5 withstands the end of elastic clip 1-2.
Elastic clip 1-2 is the cone of hollow, and the size of middle part circular hole matches with steel strand 3 external diameter.
Leakproof oxidant layer is filled with in sleeve pipe 2.
Installation of the present utility model and the course of work as follows:
1) hole.
2) the utility model is installed:
Be built in by steel strand 3 in sleeve pipe 2, the leakproof oxidant layer of filling in sleeve pipe 2 is used for steel strand 3 and injecting cement paste to isolate, and prevents it from getting rusty; Be fixed on fixed base 4 by steel strand 3 one end, steel strand 3 other end is fixed on Recyclable anchor rope head 1.
3) cement injection:
A, once grouting: once grouting pipe is apart from being preferably 100 ~ 200mm at the bottom of hole, and with Special plaster pulp grinder and grouting pump slip casting, slurry is M30 straight cement slurries, stirs, with mix with, cement paste water/binder ratio is 0.5 intensity >=30MPa.Slurries are discharged by the bottom of hole by Grouting Pipe outside hole, and rig sleeve pipe is transferred on marginal not slurry limit, overflow after slurries can stop slip casting until aperture, as there is decline in slurry face, need mend slurry till Starch Level no longer declines;
B, secondary grouting: carry out after the cement consolidating strength that secondary splitting grouting should be formed at once grouting reaches 5.0MPa, grouting pressure should be greater than 2.5MPa, and high-pressure slip-casting should select the cement paste of water/binder ratio 0.45 ~ 0.5.Secondary grouting pressure and slip casting time can be determined according to the volume of anchoring section, and segmentation is from top to bottom carried out successively.Grouting amount depends on the circumstances, and is generally flow out slurries from gap, aperture till.
4) outer protection: after slip casting, cement paste will carry out maintenance, reaching until its intensity can stretch-draw after setting.Curing time should reach anchoring body intensity and be greater than 15MPa, and reaches design strength more than 75%.
5) tensioning fixation: anchorage cable stretching, to design strength, locks by injecting cement paste maintenance.Before locking, each anchor cable of reply carries out stretch-draw, and stretch-draw value should reach design load and obtain 1.05-1.1 times, to check the uplift resistance of anchor cable.
6) anchor lock reclaims: can carry out anchor lock and reclaim after agent structure side wall completes, anchor cable reclaims and adopts mechanics recovery method, namely the steel strand 3 of tensioning fixation are first discharged pulling capacity by jack, then the recovery steel strand 3 of centre not stretch-draw are extracted from fixed base 4, thus in generation space, fixed base 4 center, crimping place is scattered, and the steel strand 3 of all the other stretch-draw are just lax also can be extracted.
It is as follows that the utility model reclaims principle:
Steel strand 3 first apply certain insurance power and then adopt briquetting 1-5 and flat head screw 1-6 to withstand the end of elastic clip 1-2, when slip casting completes and carries out stretch-draw, prestressing force is greater than insurance power, elastic clip 1-2 can produce compressive strain, under the effect of the first spring 1-4 with pulling force, briquetting 1-5 is come off;
When reclamation is performed, only steel strand 3 need be allowed to produce slight vibrations, elastic clip 1-2 will come off, steel strand 3 can be extracted out in Recyclable anchor rope head 1, namely complete and reclaim anchor cable process, the problem that the anchor cable rate of recovery is low can be solved, the rate of recovery is high and easy, greatly reduces construction cost.
