Jacking axis offset measuring device and application method thereof

Abstract

The invention discloses a jacking axis offset measuring device and an application method thereof, which relate to the technical field of engineering machinery. The jacking axis offset measuring device is simple in structure, easy to operate and high in accuracy degree. The jacking axis offset measuring device comprises two anchoring structures, a measuring structure and a steel wire, wherein the two anchoring structures are used for fixing both ends of the steel wire; orthographic projection of the steel wire coincides with that of a designed jacking axis on the horizontal plane; the measuring structure comprises a measuring bracket, a measuring ruler and a measuring plumb bob, the measuring bracket is arranged on the steel wire and can move along the steel wire, the measuring ruler is arranged at the bottom part of the measuring bracket, the top part of the measuring plumb bob passes through an axis of the steel wire, a tip of the measuring plumb bob is close to the measuring ruler, orthographic projection of the measuring plumb bob coincides with that of the steel wire on the horizontal plane, and an arbitrary scale of the measuring ruler is parallel to the steel wire. The jacking axis offset measuring device and the application method thereof are used for measuring offset between a framework jacking axis and the designed jacking axis.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a measuring device for the offset of a jacking axis and a method for using the same. Background technique [0002] With the development of urban economy and the expansion of city scale, there are more and more constructions of various municipal projects such as subways, cross-river tunnels, and sewage pipelines. As a non-excavation construction method for laying underground pipelines, the pipe jacking construction method has little impact on the surrounding environment and relatively low cost. Therefore, it has been widely used. [0003] In actual jacking, the frame jacking axis and the design jacking axis often deviate, so corrective measures should be taken to reduce the deviation between the frame jacking axis and the design jacking axis to make them as consistent as possible, otherwise it will be Affect the effect of jacking construction. However, traditional methods a...
