Shield tunnel segment joint deformation measuring device and measuring method

Abstract

The invention relates to a shield tunnel segment joint deformation measuring device. The device comprises a probe assembly, a current assembly and a data acquisition unit, and is characterized in that the probe assembly is electrically connected with the data acquisition unit through the current assembly. The probe assembly comprises a plurality of probes, each probe comprises a movable section and a fixed section which are sequentially arranged from top to bottom, the movable section can move up and down, and when the movable section moves downwards, the probe is compressed. The current assembly converts the compression amount of each probe into current intensity and transmits the current intensity to the data acquisition unit, and the data acquisition unit converts the current intensity into position information of the probe and calculates, stores and derives the slab staggering amount and the opening amount at the joint of two adjacent segments. The invention further relates to a measuring method of the shield tunnel segment joint deformation measuring device. The invention has the beneficial effects that the slab staggering amount and the opening amount at the joint of two adjacent segments can be conveniently, efficiently and accurately measured and directly obtained at the same time, and the slab staggering amount and the opening amount can be conveniently stored and guided.

Description

technical field [0001] The invention relates to the technical field of segment joint deformation measurement, in particular to a measuring device and method for segment joint deformation of a shield tunnel. Background technique [0002] With the development of technical level and equipment manufacturing industry, the shield tunneling method has become one of the alternatives for tunnel excavation, and it has become the first choice in the water-rich and weak strata and the crossing projects of major water bodies. Shield tunneling is used in my country such as It sprung up like mushrooms after rain. [0003] The shield tunnel lining is assembled by segments, and the adjacent segments are bolted to form the inner space of the tunnel, and the joints between the tunnel segments are the weak areas of its structure. Affected by construction quality, surrounding rock loads, operational loads, and the surrounding environment, excavated by the shield method is always accompanied by d...
