Abstract

The invention discloses a device for measuring freezing borehole deflection and relates to the technical field of freezing borehole deflection measuring. The device comprises an upper cover plate, a lower cover plate, a cylinder with inner screw threads and a plurality of vertical fine tuning spirals. The upper cover plate is fixed to the lower cover plate through the vertical fine tuning spirals. The cylinder with inner screw threads is fixed on the bottom end face of the lower cover plate. A transparent plate provided with a central hole is movably mounted on the upper cover plate. The centers of the upper cover plate, the lower cover plate, the transparent plate and the cylinder with inner screw threads are on a vertical straight line. Central holes are reserved on the upper cover plate and the lower cover plate correspondingly. Notches are reserved on one sides of the upper cover plate and the lower cover plate correspondingly. Two leveling tubes perpendicular to each other are disposed on the upper cover plate. An opening is reserved on one side of the cylinder with inner screw threads. A transverse rod which can rotate horizontally is mounted at the opening. A guide wheel is mounted on the transverse rod. The device is simple in structure and simple to operate, and measuring precision is improved.

Description

technical field [0001] The invention relates to the technical field of frozen borehole deflection measurement, in particular to a frozen borehole deflection measurement device [0002] ; Mainly applicable to the situation where the hole depth is less than 100 meters and the electronic inclinometer is inconvenient to use. Background technique [0003] At present, the inclinometer chuck commonly used by construction units is composed of a chuck, a center plate, a guide wheel, and a small hammer. The level ruler uses a small hammer to hit the chuck to make it level, and then mounts the theodolite to measure the casting point. The parts of the swash plate are scattered, the structure is complicated, the procedure is cumbersome to use, the operation time is long, and the error is large. Contents of the invention [0004] In order to solve many problems of the original swash plate, such as scattered parts, complex structure, cumbersome procedures, long operation time and lar...
