Embodiment Construction

[0026] see Figure 1 to Figure 3 , shows the inclinometer platform of the present invention.

[0027] The inclinometer platform 10 includes two upper struts 11 and two vertical struts 12 .

[0028] The two upper struts 11 are arranged parallel to each other and a snap ring 13 is fixed between them, the snap ring 13 is hollow cylindrical, and its axis is on the same plane and parallel to the two upper struts 11, wherein , the periphery of the snap ring 13 is provided with three first fastening bolts 14 penetrating the snap ring 13 to fasten the snap ring 13 when it is set on the freezing tube, wherein the inner diameter of the snap ring is 110 mm.

[0029] One end of the two upright rods 12 is movably connected to the ends of the upper rod 11 respectively, so that the upright rods 12 can move freely at the ends of the upper rod 11, and two second fastening rods are arranged between the two. Bolts 15 are tightened when necessary.

[0030] Wherein, the two vertical struts 12 a...

Abstract

The invention discloses a slope measuring platform. The slope measuring platform comprises two upper supporting rods and two vertical supporting rods, wherein the two upper supporting rods are parallel to each other; a clamping ring is fixed between the two upper supporting rods and is of a hollow cylinder shape; the axis of the clamping ring is coplanar and parallel to the two upper supporting rods; one end of each of the two vertical supporting rods is movably connected to the tail end of the corresponding upper supporting rod; a second fastening bolt is arranged between each vertical supporting rod and the corresponding upper supporting rod; a placement platform perpendicular to the two vertical supporting rods is arranged on the two vertical supporting rods. Therefore, the slope measuring platform is short in consumed time, and is not limited by environment positions; an operation process is simple and convenient, and a fixing structure is steady; moreover, all component parts can be disassembled completely and are convenient to carry.

Description

technical field [0001] The invention relates to the field of measurement in frozen shields, in particular to an inclinometer platform. Background technique [0002] The artificial ground freezing method is to use artificial refrigeration technology to freeze the water in the ground rock and soil, turn the natural rock and soil into frozen soil, increase its strength and stability, and isolate the connection between groundwater and underground engineering, so that it can be frozen in the frozen wall. It is a special construction technology for underground engineering construction under protection. Its essence is to use artificial refrigeration to temporarily change the properties of rock and soil to strengthen the formation. The artificial ground layer freezing method is basically not limited by the support range and support depth, and can effectively prevent water gushing and adjacent soil deformation during urban excavation and drilling construction. means. [0003] With ...
