The invention relates to a presetting and measuring device for a setting elevation of a hydrostatic leveling instrument and a measuring method, and aims at effectively solving the setting elevation presetting problem of the hydrostatic leveling instrument and striving to enable the device and the method to achieve the advantages of being simple, practical and economical.According to the technical scheme, the presetting and measuring device for the setting elevation of the hydrostatic leveling instrument is characterized by being composed of a datum water tank, a communication pipe, a pressure gauge and two switch valves, wherein one switch valve is installed at the bottom of the datum water tank and connected with one end of the communication pipe, and the other end of the communication pipe is connected with the pressure gauge through the other switch valve.The device is suitable for determining the setting elevation of the hydrostatic leveling instrument and also can be used for setting embedding of other elevation measuring points.
Description
technical field [0001] The invention relates to the technical field of deformation measurement, in particular to a static level gauge installation elevation preset measurement device and measurement method. It is mainly used to determine the installation elevation of the static level, and can also be used for the installation and embedding of other elevation measuring points. Background technique [0002] At present, the static level has been widely used in the settlement monitoring of tunnels, bridges, houses and other buildings, but the level is often used to measure the installation elevation when the static level is installed. Due to the high requirements of the erection conditions of the level and the limitation of the visibility conditions, etc., The actual operation is very inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is: in view of the above reasons, the present invention provides a static level insta...
