Prefabricated pipe gallery assembling system

Abstract

The invention provides a prefabricated pipe gallery assembling system which comprises a plurality of tensioning devices, a plurality of tensioning adjusting devices and a control device. Each tensioning device comprises a steel strand and a tensioning drive, wherein the steel strand penetrates through tensioning holes of two adjacent pipe gallery sections, the tensioning drive is used for tensioning the steel strand, and an optical fiber is arranged in the steel strand; the tension adjusting device comprises a collector used for collecting and demodulating tension data and an optical fiber sensor in communication connection with the collector, and the optical fiber sensor is used for detecting the wavelength change of the optical fiber and is arranged in the steel strand; the control device is in communication connection with the tensioning adjusting device and the tensioning drive. The optical fiber is arranged in the steel strand, and the optical fiber strain is monitored in real time through the optical fiber sensor and the collector, so that the tension stress of the steel strand can be regulated and controlled in real time, the tension force of each tension point is ensured to be greater than a preset value, the tension quality is ensured, the sealing performance of the pipe gallery section is improved, and the normal operation and maintenance of the pipe gallery can be ensured.

Description

technical field [0001] The invention relates to the technical field of pipe gallery construction, in particular to a prefabricated pipe gallery assembly system. Background technique [0002] The existing prefabricated pipe gallery mainly relies on the tension and locking of prestressed steel strands for assembly. According to the number of cabins, the hydraulic tension system will set multiple tension points on the assembly section. During the tensioning process, the synchronization of each tensioning point and whether the tension value of each point can meet the design requirements will directly affect the waterproof performance of the pipe gallery joint waterstop strip joint, and the traditional hydraulic prestressed tensioning system is difficult. Quantitative control, and in the process of use, due to the different tensile stress of each tension point, the tension stress of a certain tension point is likely to be insufficient, which may easily lead to leakage of the pref...
