Detection device and method for recoverable pressure dispersion type anchor cables

Abstract

Embodiments of the invention disclose a detection device and method for recoverable pressure dispersion type anchor cables. The device comprises: a dispersion type anchor cable guider, which guides a plurality of to-be-detected anchor cables to pass through the dispersion type anchor cable guider; a plurality of jacks, which are vertically arranged at the top of the dispersed anchor cable guider, wherein each anchor cable to be detected independently locks one anchor cable to be detected; a power assembly, which is connected with the jacks, wherein the jacks apply upward pulling force to the anchor cables to be detected under the power action of the power assembly; and a displacement measuring mechanism, which is arranged at the parts, penetrating out of the jacks, of the plurality of to-be-detected anchor cables so as to measure the displacement of the to-be-detected anchor cables generated under the action of the upward pulling force of the jacks. According to the invention, synchronization effect during detection is ensured, the number of workers required for detection is reduced, overall test cost is reduced, and reasonable accuracy of detection is ensured.

Description

technical field [0001] The invention relates to the field of anchor cable detection, more specifically to a detection device and method for a recoverable pressure dispersion type anchor cable Background technique [0002] The foundation pit support anchor cable is mainly used in the foundation pit support stage to ensure that the foundation pit has sufficient anchoring force to resist the active earth pressure on the foundation pit without inward collapse. [0003] Ordinary anchor cables mainly obtain pullout resistance through the bonding between the anchor cable and the grouting body in the anchor section, but the bond stress distribution of ordinary anchor cables on the anchorage length is uneven, which easily leads to the bond stress at the proximal end of the anchor section. Concentration is not conducive to the work effectiveness of the anchor cable, and once a certain anchor cable is damaged, it is very likely to cause the failure of the entire hole anchor cable, and ...

Problems solved by technology

[0006] 1. For the detection of parallel jacks, if one jack corresponds to one pressurized oil pump, four oil pumps are required to detect the four-bar anchor cable, and each oil pump needs to be equipped with an inspector. The required personnel are more than twice that of ordinary inspections. , and the synchronous pressurization rate of different oil pumps is difficult to ensure consistency, and it is difficult to achieve a completely synchronous effect
