Abstract

The invention discloses a self-falling type flexible leveling rod and a using method thereof. The self-falling type flexible leveling rod comprises a foldable tripod, a telescopic rod, a flexible leveling rod body and a heavy punch, and the telescopic rod is connected with a screw rod on a bearing platform at the top of the foldable tripod through threads; a cross rod is connected to the top of the telescopic rod, a flexible leveling rod is fixed to the other end of the cross rod, and a circular counter weight is connected to the bottom of the flexible leveling rod. The principle that the flexible leveling rod is automatically erected under the action of gravity is utilized, uncertain errors caused by manual leveling rod supporting are overcome, meanwhile, the adjustability of the length of the flexible leveling rod body is considered, and the proper telescopic rod is selected, so that the length of the leveling rod has a large adjusting space, and special site conditions during leveling point measurement can be overcome. The device is simple in structure, is small and portable after being folded, facilitates the operation of field leveling operation, is very high in practicality,is wide in application prospect, and is better in economic benefit.

Description

technical field [0001] The invention belongs to the field of civil engineering geotechnical testing, and in particular relates to a self-falling flexible level gauge and a using method thereof. Background technique [0002] The definition of the leveling rod is: the leveling rod is a ruler used for leveling, and it is made of high-quality wood or fiberglass, aluminum alloy and other materials. Commonly used leveling rulers include tower ruler, folding ruler and double-sided leveling ruler. [0003] Under existing conditions, using a leveling rod to keep it vertical is mostly an artificial support. Chinese patent (application publication number: CN108088415A) discloses a support-free leveling rod, which is to support the leveling rod by setting up a tripod for leveling . The Chinese patent (Application No.: 201711494226.1) of "a leveling rod with an automatic straightening device", in which a gyroscope is installed in the device, and the vertical is corrected by electronic ...
