Abstract
An anchor wire construction leaf proof antisepsis equipment for the rock and soil anchoring construction mainly solve the problem that the grouting liquid drains away substantively and corrodes the anchor line when the stitching hole is two large in the anchoring construction. The peripheral of the stretching segment is sheathed with a tube-shaped geotextile and a canvas. When grouting the weight of the serous supports the geotextile and makes the geotextile combine with the hole wall closely, thereby preventing the serum running off in the direction of the cracks and the cavitations and guaranteeing the construction quality.
Description
Technical field
The utility model relates to device used in the geotechnical anchor engineering, the leakproof anti-corrosive apparatus in particularly a kind of anchor cable construction.
Background technology
At present, distinguish developmentally at rock mass detrition, crack hole, when adopting the anchor cable strengthening construction, hole wall is worn by crack, hole behind the pore-forming, and slurries will run off in a large number during grouting, then is difficult to realize sealing of hole grouting, before sealing of hole grouting, must adopt consolidation grouting for this reason, the seam hole is blocked, and following anchor cable behind the cleaning bottom of hole is then by interior anchoring section grouting, stretch-draw, locking, sealing of hole grouting (non-bending steel cable anchor cable grouting procedure can once be finished).
Because the existence of crack, hole during consolidation grouting, adopts cement mortar (or mixing other fillers) to add the accelerating admixture leak stopping.But slurries will run off in a large number when crack, hole are too big, the difficult quality guarantee of sealing of hole grouting, also will there be hidden danger in the anticorrosion problem of anchorage cable stretching section thereupon, this has not only improved cost greatly, and owing to employing limit consolidation grouting leak stopping, limit cleaning bottom of hole pore-forming cause efficient to reduce greatly, construction delay.Simultaneously, because a large amount of slurries flow into rock mass, usually cause with serious consequences such as near anchor cable hole, grout pipe, drain hole, the drain of finishing operation are blocked.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, respond well anchor cable construction leakproof anti-corrosive apparatus, thereby improves work efficiency, the reduction of erection time, improves construction quality.
In order to realize the purpose of this utility model, intend taking following technical scheme:
Stretch-draw section outer race at anchor cable is equipped with the tubular geotextiles.
Above-mentioned tubular geotextiles outside also is equipped with canvas.
Advantage of the present utility model is simple in structure, realizes that easily easy and simple to handle feasible, with low cost, the leakproof antiseptic effect is good, uses it can avoid all harm that spillage is caused when anchor hole is in the milk, thereby improves work efficiency, the reduction of erection time, improves construction quality.
Description of drawings
Accompanying drawing is structure of the present utility model and user mode schematic diagram.
The specific embodiment
The disclosed structure of accompanying drawing is an embodiment of the present utility model.Among the figure, 1 is geotextiles; 2 is canvas; 3 are the stretch-draw section; 4 are boring; 5 is anchor cable; 6 is the plastics Grouting Pipe; 7 is the crack; 8 is hole; 9 is guiding cap; 10 is anchor head; 11 is ground.
Principle of the present utility model is: the purpose of the anchor cable body stretch-draw section grouting that non-bending steel cable is formed is in order to protect steel strand, with geotextiles, the post-grouting of canvas parcel, not only to reach the purpose of protection steel strand but also can avoid slurries to run off.After steel strand were wrapped up by geotextiles, grout coordinate ratio was constant in the construction, guarantees its intensity, and the weight by slurries during grouting can strut geotextiles, and itself and hole wall are combined closely, thereby stoped the past crack of slurries, hole direction to run off effectively.The bag canvas is for the protection geotextiles, avoids when the anchor cable hand-hole by the hole wall hanging breaking.
When the utility model is implemented, 400 gram geotextiles can be placed on cutting on the fine canvas, its length is identical with the stretch-draw section, and the diameter after anchor cable is wrapped is bigger by 10% than bore diameter, and it is stitched into tubular, is enclosed within anchor cable body stretch-draw section, and two ends are fixed on the anchor cable body.
Use of the present utility model has prospect preferably, China's hydroelectric project, expressway slope etc. from now on, to face a large amount of fragmented rock bodies and reinforce improvement, when anchor cable construction, cement paste runs off and is difficult to avoid, and the solution of this problem is not only the direct investment of saving engineering, also can shorten the needed duration of consolidation grouting operation greatly, avoid again because various interference and the future trouble that spillage causes.
Claims (2)
1, a kind of anchor cable construction leakproof anti-corrosive apparatus is characterized in that: the stretch-draw section outer race at anchor cable is equipped with the tubular geotextiles.
2, by the described anchor cable construction leakproof of claim 1 anti-corrosive apparatus, it is characterized in that: above-mentioned tubular geotextiles outside also is equipped with canvas.
