Laser Inclinometer and Inclinometer Method

Abstract

The invention discloses a novel laser tilt checking device and a novel laser tilt checking method, aiming at solving the problems that the loss is great, the precision is low, and the efficiency and the digital degree are low in the tilt checking tube process adopted for manually checking the perpendicularity of a checked object in the prior art, and in the prior art, the perpendicularity of the checked object is measured by adopting a conventional tilt meter process, so that the normal tilt meter cannot be easily installed and positioned on the checked object. The tilt laser checking method comprises the following steps: ingeniously combining laser with the tilt meter, precisely and quickly positioning the laser tilt meter on the checked object by virtue of laser, then, reading the perpendicularity deviation condition of the checked object in real time by virtue of the tilt meter of a tilt checking integrated circuit board. The novel laser tilt checking device has the advantages of convenience in position and installation of the laser clinometers on the checked object, high checking precision, high checking efficiency, simplicity and convenience in operation.

Description

technical field [0001] The invention relates to a laser inclinometer and an inclination measuring method thereof. Background technique [0002] At present, underground works are often constructed using the top-down method. The reverse construction method of underground engineering is an advanced construction technology that reduces deformation of foundation pit, saves support costs, shortens construction period, and has the advantages of green construction such as energy saving and environmental protection. [0003] In the construction process of the deep foundation upside-down method, the intermediate support columns are composed of concrete piles and steel columns, and the steel columns are inserted at the upper end of the concrete piles. Among them, some steel columns of the intermediate support columns are constructed during the upside-down construction process. It is a temporary structural member that replaces the engineering structural column, which is mainly used to ...

Problems solved by technology

Otherwise, the additional bending moment of the steel column will be increased, resulting in the stress deviation of the structure, which will cause structural damage

[0004] At present, the existing technology mainly uses the inclinometer method to measure the inclination of the steel column. This method has a large loss, low precision, low efficiency, and low degree of digitization; It is very difficult to install and position on the top, which is very time-consuming and labor-intensive

Therefore, no matter whether the inclinometer tube method of tying the inclinometer tube on the steel column or using the crane, laser theodolite and scaffolding to install the inclinometer on the steel column, it cannot adapt to the reverse construction of the construction project and the verticality of the steel column is efficient and high. Accurate, high-quality measurement requirements, so it is necessary to develop a new type of laser inclinometer and its inclinometer method with high measurement accuracy, high efficiency and convenient operation
