Embodiment Construction

[0029] The comprehensive detection method for the anchorage state of the prestressed anchor cable in this embodiment includes the following steps:

[0030] a. Detect the anchor length, grouting fullness, prestress and corrosion degree of the prestressed anchor cable, and obtain the measured values ​​of the four indicators;

[0031] b. The comprehensive inspection of anchorage status is divided into anchorage quality inspection and anchorage safety inspection;

[0032] b1 Anchorage quality inspection is divided into anchorage quality single index comparison inspection and anchorage quality comprehensive inspection;

[0033] Anchorage quality single index comparative inspection: According to the three measured values ​​of the anchor length, grouting fullness and prestress measured in step a, the measured values ​​are compared with the standard values ​​of each quality index. If there are unqualified items, the anchorage The quality is unqualified; otherwise, carry out comprehen...

Abstract

The invention discloses a comprehensive detection method of anchoring status of a prestress anchor cable. By detecting the anchor length, grouting plumpness, prestress and corrosive degree of the prestress anchor cable, the method conducts the contrastive analysis and comprehensive analysis of a single index and consequently analyzes the anchorage quality and safety performance of the prestress anchor cable. The detection method has great significance to control the construction quality of newly built anchoring engineering and grasp the operating status and safety of the existing anchoring engineering.

Description

technical field [0001] The invention relates to a method for detecting civil engineering structures, in particular to a method for comprehensively detecting the anchoring state of prestressed anchor cables. Background technique [0002] The prestressed anchor cable anchoring technology is a slope reinforcement technology that develops rapidly and is widely used in recent years. Prestressed anchor cable anchoring can give full play to the self-supporting ability of rock and soil, adjust and improve the self-strength and self-stabilization ability of rock and soil, and can provide a strong active support method, which is the result of non-prestressed support measures. unattainable. [0003] Anchorage is a permanent project, concealed project and prestressed project, and the safety and stability of the project depends to a large extent on the reinforcement of prestressed anchor cables. The anchoring quality and safety of the prestressed anchor cable are the necessary conditio...
