Abstract
A longitudinal no-slip strain test optical fiber cable comprises a tight package sheath layer (2) that is externally extruded by the test optical fiber cable (1), and an outer sheath layer (3) that is externally extruded by the tight package sheath layer (2). The inner wall of the outer sheath layer (3) has a cylindrical shape and the outer wall has a corrugated tube shape. The tight package sheath layer (2 is a nylon tight package layer, and the outer sheath layer is a protective layer of polyester resin elastomer. The utility model is widely applicable in the strain tests of concrete buildings, bridges and dams, etc. The cable has the advantages of that the cable has a strong binding force with the tested object and no horizontal slip, which substantially elevates the precision and sensitivity of the strain data tests.
Description
Affiliated technical field
The utility model relates to a kind of optical communication optical cable, and especially a kind of test of vertical no slippage strain is vertical no slippage test optical fibre cables with optical cable.
Background technology
The outer jacket surface of existing strain testing optical cable is smooth cylindrical, this kind strain testing optical cable before concrete is imbedded in construction as surface contamination dust, greasy dirt etc., after imbedding concrete structure, bridge, dam body, hold thing between optical cable outer jacket and measured object and produce straight skidding, strain data be can not accurately reflect, the precision and the sensitivity that detect strain data had a strong impact on.
Summary of the invention
In order to overcome existing strain testing optical cable outer jacket smooth in appearance and detected material adhesion weakness, easily cause straight skidding and influence strain testing precision and the relatively poor deficiency of sensitivity, the utility model provides a kind of test optical fibre cables of not having the slippage strain, it is combined firmly with tested object, vertically no slippage significantly improves the sensitivity and the measuring accuracy of test optical fibre cables.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of vertical no slippage strain testing optical cable is to constitute at light transmitting fiber outer coated sheath layer, it is characterized in that with the strain testing light transmitting fiber be inner core, the hard-pressed bale restrictive coating that outsourcing extrudes, outside the hard-pressed bale restrictive coating, extrude external sheath layer, the inwall of this external sheath layer is cylindrical, the outer wall of external sheath layer be shaped as bellow-shaped, the above-mentioned described hard-pressed bale restrictive coating that extrudes outside measuring fiber is a nylon hard-pressed bale layer, and the above-mentioned described external sheath layer that extrudes outside the hard-pressed bale restrictive coating is a vibrin elastic body sheath.
The beneficial effects of the utility model are between measuring fiber and the hard-pressed bale sheath, each interlayer firm binding force between hard-pressed bale sheath and the outer jacket, do not produce straight skidding, the appearance of external sheath layer is a bellow-shaped, be solidified as one with measured object after being poured into the concrete structure, bridge, dam body of tested strain, can not produce straight skidding, thereby can reflect measured object strain situation occurred more objectively, significantly improve strain testing precision and sensitivity.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the local longitudinal sectional view of the utility model.
In Fig. 1: 1. test and use light transmitting fiber, 2. hard-pressed bale restrictive coating, 3. external sheath layer.
Embodiment
In Fig. 1, a kind of vertical no slippage strain testing optical cable is made of light transmitting fiber outer coated sheath layer, it is characterized in that the outer hard-pressed bale restrictive coating (2) that extrudes of strain testing optical fiber (1), the outer external sheath layer (3) that extrudes of hard-pressed bale restrictive coating (2), the inwall of this external sheath layer (3) is cylindrical, outer wall be shaped as bellow-shaped.The outer hard-pressed bale restrictive coating (2) that extrudes of above-mentioned described measuring fiber (1) is the tight restrictive coating of nylon, and the above-mentioned described external sheath layer (3) that extrudes outside hard-pressed bale restrictive coating (2) is a vibrin elastic body sheath.
Claims (3)
1, a kind of vertical no slippage strain testing optical cable is made of light transmitting fiber outer coated sheath layer, it is characterized in that the outer hard-pressed bale restrictive coating (2) that extrudes of measuring fiber (1), hard-pressed bale restrictive coating (2) is outer to extrude external sheath layer (3), and the inwall of this external sheath layer (3) is cylindrical, outer wall be shaped as bellow-shaped.
2, vertical no slippage strain testing optical cable according to claim 1 is characterized in that above-mentioned described hard-pressed bale restrictive coating is a nylon hard-pressed bale layer.
