Abstract

The invention belongs to the field of civil engineering testing equipment, and relates to a full-automatic testing apparatus for nonmetal anti-floating anchor long-term deformation. A fastening nut and an anchoring tray are connected to an anchor rod body, a steel shim is placed on the surface of a concrete cushion, an I-shaped buttress is placed on the upper surface of the steel shim, a second cross-core steel base plate is placed on the upper surface of a cross-core counter-force beam, and the second cross-core steel base plate, an oil pressure type cross-core jack, a first cross-core steelbase plate and a loading sensor are sequentially stacked on the upper surface of the cross-core counter-force beam from bottom to top; the oil pressure type cross-core jack is connected with an electric oil pump, and the electric oil pump is connected with an anchor rod test testing system and a repeater; the inner wall of a semi-circular steel pipe is pasted to the outer side of the anchor rod body; an angle iron is welded to the outer side face of the semi-circular steel pipe, and a centering support is fixed to the outer surface of the anchor rod body of an anchor section; and displacementsensors are installed on the surfaces of the angle iron and a grouting body. The full-automatic testing apparatus is simple in structure, convenient to test, high in testing accuracy, high in maneuverability and capable of achieving full-automatic monitoring.

Description

Technical field: [0001] The invention belongs to the field of civil engineering test equipment, and relates to a long-term deformation test device for a non-metallic anti-floating anchor rod, in particular to a fully automatic test device for the long-term deformation of a non-metallic anti-floating anchor rod. Background technique: [0002] With the development and utilization of urban underground space, the foundation burial depth of buildings continues to increase, and the problem of anti-floating has become more and more prominent. The pole has the advantages of strong adaptability to the stratum, dispersing stress, convenient construction, cost saving, and large bearing capacity in hard rock and soil layers. The emergence of glass fiber reinforced polymer (GFRP) bolts has added new means to rock and soil anchoring, especially the excellent corrosion resistance and anti-electromagnetic interference characteristics of GFRP materials, which have solved the problems that pl...
