Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a real-time measurement and monitoring system for the verticality of lattice columns in construction engineering. Background technique [0002] In current construction projects, it is still a difficult problem to monitor the verticality of one column and one steel lattice column in the reverse construction method. If the vertical accuracy of the steel lattice column is to reach 1 / 500 (projection to pipe length ratio) or higher , it is difficult to guarantee in actual construction operations. [0003] At present, the method of inclinometer tube is commonly used in construction engineering to measure the vertical accuracy of the steel lattice column, that is, the inclinometer tube is bound on the outside of the steel lattice column, and the inclinometer tube is parallel to the central axis of the steel lattice column. After the lattice column is lowered into the shaft hole,...

Problems solved by technology

[0005] No matter which method we use in engineering, we have to go through a process of measurement→adjustment→retest→adjustment→retest→... such a process is time-consuming and laborious, and the efficiency is very low, and this measurement method is widely used. Affected by various factors, there are many errors, such as the production error of the inclinometer tube, that is, the error caused by the wall thickness of the inclinometer tube and the depth of the guide groove; the inclinometer is caused by temperature changes at the bottom and top of the inclinometer tube. error; error caused by the way the measurer pulls and releases the cable

In the above three cases, the errors caused by the latter two are often large, and these errors will have a serious impact on the quality of the project.

[0006] In addition, there are also a few researchers who directly use high-precision inclinometers that can measure small angles to measure the verticality of steel lattice columns in the upside-down method of column-by-pile construction. Due to the difficulty of positioning and installation, and the error caused by the positioning accuracy will directly affect the vertical accuracy of the steel lattice column measured in the future, it is difficult to really apply it in engineering
