Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 schematically shows a kind of a kind of end optical fiber circuit protection dress of embodiment according to the present utility model
It sets.As shown in Figure 1, the device includes the bend pipe 1 of an arc, bend pipe 1 is generally made of materials such as stainless steels, and radian is preferred
It is 180 °.And it is equipped with a connector 11 at the both ends of bend pipe 1, connector 11 is preferably that internal thread nut is arranged
It is usually one Deng, connector 11 and bend pipe 1, can also be designed to when necessary dismountable.In addition, on the outer wall of bend pipe 1
Equipped with rough striped portion 12, the frictional force that striped portion 12 is capable of increasing the outer wall of bend pipe 1 and external environment is in contact, with
Enable bend pipe 1 stronger in Transducers Embedded in Concrete bored concrete pile etc., is not easy to slip.
Fig. 2 shows the use principle of the stake end optical fiber circuit protective device in Fig. 1.As shown in Fig. 2, in the every of bend pipe 1
Equal 2 connector 11 of casing is held to be connected with a casing 2, wherein the end of casing 2 is equipped with external screw thread, thus can be with connector 11
On internal screw thread match, casing 2 is mounted on bend pipe 1.
When carrying out strain testing, the drilling construction of stake is irrigated in foundation soil first, then makes bored concrete pile
Steel reinforcement cage, then the inside that mounting hole is placed into casing 2 that mutual installation is fixed, and by optical fiber 3 from one of casing 2
Insertion, and be pierced by after passing through bend pipe 1 from another casing 2；Optical fiber 3 is connected to a light to receive on instrument 4, while to bend pipe 1
With grout injection in casing 2, and in stake holes casting concrete at cast-in-place concrete pile.As a result, carry out load test or
Under working condition, data shown by instrument 4 can be received by observing light, realize the strain testing to cast-in-place concrete pile.Wherein,
Optical fiber 3 is known as the position of turning back of the optical fiber circuit at stake end by the position of bend pipe 1, by the protection of bend pipe 1, bending angle
It is more steady, and be not damaged.
In addition, can pour to form multiple cast-in-place concrete piles, and be used cooperatively when related test scope is larger
