Longitudinal horizontal displacement meter anchoring end mounting structure and construction method

Abstract

The invention discloses a longitudinal horizontal displacement meter anchoring end mounting structure and a construction method. The longitudinal horizontal displacement meter anchoring end mounting structure comprises a soft base and four anchor rods inserted into the soft base; the four anchor rods are arranged on the soft base in a # shape; a steel base plate is placed in the center of the # shape; the steel base plate is fixed on the soft base through a first bolt; the flange end of the horizontal displacement meter is arranged on the steel base plate through a second bolt; a concrete block is poured on the outer side of the soft base; the steel base plate and the flange end of the horizontal displacement meter are pre-embedded in the concrete block; and the soft base and the concreteblock are fixed through the exposed ends of the anchor rods. The steel base plate is arranged on the surface of the soft base and the concrete is poured to fix, so the problem that the longitudinal horizontal displacement meter needs to be mounted when the soft base is encountered is solved, the anchoring end of the horizontal displacement meter and the soft base are connected together and are arranged firmly, the measured value is reliable, and a transport management personnel can effectively master the operation state and the safety state of a dam through the change of the measured value ofthe horizontal displacement meter.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower applications, and in particular relates to an installation structure and a construction method for an anchor end of a longitudinal horizontal displacement meter. Background technique [0002] When selecting a water retaining dam, if the surrounding rock at the dam site is a soft foundation, generally choose a local material dam such as a rockfill dam. The displacement of the dam body is one of the key monitoring points of the rockfill dam. The displacement of the dam body is divided into surface displacement and internal displacement. The horizontal displacement meter is used as a conventional monitoring instrument for monitoring the internal horizontal displacement of the dam body. The principle of the instrument to monitor the deformation of the dam body along the river direction is as follows: the two ends of the installation elevation installed inside the dam body alo...
