Embodiment Construction

[0024] Below in conjunction with embodiment technical solution of the present invention is made more specific description:

[0025] like figure 1 As shown, a glass fiber-reinforced concrete pile containing optical fibers includes a pile body 1 and a glass fiber reinforcement 2 that is located in the pile body 1 and constitutes the longitudinal main reinforcement of the pile body 1. The glass fiber reinforcement 2 has built-in glass fiber reinforcement 2 An optical fiber 3 arranged in the longitudinal direction and a plurality of strain sensors 4 and / or acoustic wave sensors 5 arranged at intervals along the longitudinal direction of the glass fiber rib 2, the detection signals of the strain sensors 4 and acoustic wave sensors 5 are output through the optical fiber 3.

[0026] The glass fiber reinforcement 2 is bound on the reinforcement cage in the pile body 1, and the end of the optical fiber 3 extends beyond the end of the pile body 1 to connect with the signal acquisition m...

Abstract

The invention relates to a glass fiber-reinforced polymer concrete pile containing optical fibers. The glass fiber-reinforced polymer concrete pile comprises a pile body and glass fiber-reinforced polymers located in the pile body to form a longitudinal main polymer of the pile body; an optical fiber arranged in the length direction of the corresponding glass fiber-reinforced polymer and a plurality of strain sensors and/or sonic wave sensors arranged along the length direction of the corresponding glass fiber-reinforced polymer at intervals are arranged in each glass fiber-reinforced polymer; and a detecting signal of the strain sensors and a detecting signal of the sonic wave sensors are outputted by the corresponding optical fiber. After the glass fiber-reinforced polymer concrete pile disclosed by the invention is used as a building foundation, even the glass fiber-reinforced polymer concrete pile is under a concealed condition, the situations whether the glass fiber-reinforced polymer concrete pile is complete or not or the stress is changed or not can also be detected in a real-time manner; strain data of the pile body is transmitted to a signal acquiring module through the optical fibers by the strain sensors, so that the situation whether the stress of the concrete pile is changed or not can be achieved; the wave velocity of sonic waves broadcasted in the pile body is transmitted to the signal acquiring module by the sonic wave sensors, so that the wave velocity distribution of the sonic waves in the pile body can be achieved; and through the changes of the wave velocity, the situation whether the pile body is complete or not can be judged, and according to the wave velocity distribution, the length of the pile body can also be achieved.

Description

technical field [0001] The invention belongs to the field of building foundations, in particular to a fiberglass-reinforced concrete pile containing optical fibers. Background technique [0002] Concrete piles are the basis of construction, including prefabricated piles and cast-in-place piles. The integrity of the concrete piles directly affects the quality of construction projects. After the construction of general concrete piles, especially the permanent and concealed concrete piles, it is difficult for the inspector to directly know whether the structure of the pile body is complete and whether the force on the pile body meets the design requirements. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a fiberglass-reinforced concrete pile containing optical fibers. [0004] In order to realize the purpose of the present invention, the present invention has adopted following technical scheme: [0005] A gl...
