Abstract

The invention belongs to the technical field of in-situ test equipment and relates to a creep test loading device for a non-metal anti-floating anchor. An anchor body is of a solid rod-shaped structure and is bonded with a steel casing pipe. H-shaped steel is perpendicular to a concrete cushion layer and is symmetrically arranged on the two sides of the anchor body. A counterforce beam is a box-type section formed by welding two pieces of H-shaped steel. The counterforce beam is provided with a steel base plate. The steel base plate, a penetrating jack, a spring, a steel plate, an anchor cable axial force meter and an anchorage device are stacked on the counterforce beam and arranged outside the steel casing pipe in a sleeved mode. The anchorage device is welded to the outside of the steel casing pipe. A dial indicator is arranged on L-shaped organic glass in an erecting mode. The L-shaped organic glass is arranged on the interface of the concrete cushion layer and the anchor body. A magnetic indicator base of the dial indicator is arranged on a standard beam arranged on a concrete buttress. The concrete buttress is arranged on the concrete cushion layer. The creep test loading device is simple in overall structure, convenient to install, high in testing precision and high in operability.

Description

Technical field:

[0001] The invention belongs to the technical field of in-situ test equipment, and relates to a non-metallic anti-floating anchor rod creep test loading device, which is used for measuring and analyzing the creep deformation of the non-metallic anti-floating anchor rod. Background technique:

[0002] With the development and utilization of urban underground space, the foundation depth of buildings continues to increase, and the problem of anti-floating becomes more and more prominent. The bolt has the advantages of strong stratum adaptability, dispersing stress, easy construction, cost saving, and large bearing capacity in hard rock and soil layers. The appearance of glass fiber reinforced polymer (GFRP) bolts has added a new means for geotechnical anchoring, especially the excellent corrosion resistance and anti-electromagnetic interference characteristics of GFRP materials, which solves the problems that plagued the geotechnical anchoring industry.
