Abstract
The utility model provides a rock earth corrosion-proof anchorage cable with flexible self-sealing structure under the anchor that relates to a pre-stressing tendon anchoring body device, comprising an integral anchorage cable body and an outer anchor head. The anchorage cable is characterized in that: the anchorage cable is provided with a flexible self-sealing structure under the anchor successively assembled by an anchorage (1), an anchoring bottom plate (2), a sealing ring (14), a flexible sealing cylinder (3), a sealing device, and a thermal shrinkable sleeve (9) ; one end of the flexible sealing cylinder is fastened on the sealing device and forms an integral with the thermal shrinkable sleeve, the sealing device and the anchorage cable body; the other end of the flexible sealing cylinder is pressed on the anchoring bottom plate (2) by the sealing ring (14) on which the anchorage is directly pressed; the anticorrosion fat and oil (12) is filled in an under anchor sealing cavity formed by the anchorage (1), the anchoring bottom plate (2), the sealing ring (14), the flexible sealing cylinder (3) and the sealing device. The under anchor free segment of the anchorage cable, which is provided with triple sealing of mortar, the sealing device and anticorrosion fat and oil, reinforces largely the anticorrosion capacity of the anchorage cable under anchor and consequently enhances the service life of the whole anchorage cable.
Description
Technical field:
The utility model relates to a kind of presstressed reinforcing steel anchoring body device, and particularly a kind of have an anticorrosion anchor cable of the ground of flexible self sealing structure under the anchor.
Background technology:
In the current prestressing force geotechnical engineering practice, the engineering of utilizing prestress anchorage cable to reinforce is more and more, yet the anticorrosion process of anchor cable also lags far behind the application demand of anchor cable.Investigation result from international prestress anchoraging association, anchor cable is the free section that occurs in anchor cable because of the inefficacy major part that is corroded, the anchor lower part that particularly links to each other with anchor head, though the appearance of unbonded prestressing tendon has improved the interior anchoring section antiseptic property of prestress anchorage cable, but the free section for prestress anchorage cable just adopts traditional perfusion mortar anticorrosion, not having other effective anti-corrosion measures, is the main cause that causes anchor cable to be corroded and to lose efficacy.
Summary of the invention:
The technical problems to be solved in the utility model is: existing ground anchorage is perfect inadequately with the anti-corrosion measure of the free section of prestress anchorage cable, and the imperfect problem of antiseptic property provides a kind of anticorrosion anchor cable of ground that flexible self sealing structure is arranged under the anchor of anchor cable.
The scheme that solves its above-mentioned technical problem is: a kind of have an anticorrosion anchor cable of the ground of flexible self sealing structure under the anchor, comprise the non-bonded anchorage cable cable body that fuses and by ground tackle, the anchor head that anchor plate constitutes, it is characterized in that: this anchor cable also has by ground tackle, anchor plate, joint ring, the flexible sealing tube, sealing device, thermal shrinkable sleeve assembles flexible self sealing structure under the anchor of formation successively, flexible sealing tube one end is fastened on the sealing device, by thermal shrinkable sleeve and sealing device, the anchor cable cable body is linked to be an integral body, joint ring is pressed in the other end of flexible sealing tube on the anchor plate, ground tackle directly is pressed on the joint ring, and anticorrosion grease is filled in by ground tackle, anchor plate, joint ring, in the anchor lower seal chamber that flexible sealing tube and sealing device form.
In the anchor lower seal chamber that sealing device and ground tackle, anchor plate, joint ring, flexible sealing tube form.
Owing to adopt said structure, the utility model have that the anticorrosion anchor cable of the ground of flexible self sealing structure with the beneficial effect that existing ground anchor cable is compared generation is under the anchor:
1, strengthened the antiseptic power of the free section of anchor cable cable body greatly, improved the application life of whole anchor cable, existing ground anchor cable is perfusion mortar one deck preserving and sealing in the anchor lower part that links to each other with anchor head, to have mortar, anchor lower seal chamber and an anticorrosion grease triple seal anticorrosion for the anticorrosion anchor cable of the ground of flexible self sealing structure that has under the anchor of the utility model, strengthened the antiseptic power of the free section of anchor cable cable body greatly, thus the application life of having improved whole anchor cable.
2, can resist the above hydraulic pressure of 0.35Mpa, can completely cut off of the influence of outside aqueous vapor, play permanent corrosion-resistant effect the anchor cable body.
3, adopt anchor plate, joint ring, flexible sealing tube, sealing device, thermal shrinkable sleeve integral installation, can effectively improve the sealing reliability of self sealing structure.
4, having under the anchor the anticorrosion anchor cable of the ground of flexible self sealing structure can on-the-spotly install, installs simple and reliable, and since employing be flexible self sealing structure under the anchor, can adapt to position, anchor cable hole and ground tackle mounting hole site deviation reaches 7 °, it is convenient to construct.
Below, the technical characterictic to the anticorrosion anchor cable of ground that the utlity model has flexible self sealing structure under the anchor is further described in conjunction with the accompanying drawings and embodiments.
Description of drawings:
Fig. 1: the utility model have an anticorrosion anchor cable structure schematic diagram of the ground of flexible self sealing structure under the anchor.
