Description

A kind of bracket for civil engineering measuring instrument

technical field

The invention relates to the field of civil engineering, in particular to a support for a civil engineering measuring instrument.

Background technique

The construction of an engineering facility generally has to go through three stages of survey, design and construction. It is necessary to use engineering geological survey, hydrogeological survey, engineering survey, soil mechanics, engineering mechanics, engineering design, building materials, construction equipment, construction machinery, construction economy knowledge in the fields of construction technology, construction organization, and technologies such as electronic computers and mechanical testing.

Among them, civil engineering is a discipline with strong practicality. In the early days, civil engineering was developed through engineering practice, summarizing successful experiences, and especially learning from failures. For civil engineering, the measurement of the geographical environment is an indispensable practical and theoretical basis, mainly because the objective conditions of most of the sites are too complex, and it is difficult to carry out indoor experiments or field tests and theoretical analysis. For example, the state of stress and deformation of foundations, tunnels and underground projects and their changes with time, so according to the needs of the project, the measurement in the early stage, construction and acceptance is very critical.

Common measuring instruments include level, theodolite, total station, concrete rebound tester, crack width gauge, floor thickness gauge, etc. The above instruments are high-precision electronic instruments, which have extremely high stability and fine angle adjustment. requirements. For example, a total station, that is, a total station electronic distance meter (Electronic Total Station), is a high-tech measuring instrument integrating light, machine and electricity. A surveying and mapping instrument system integrating the functions of distance) and height difference measurement. Compared with the optical theodolite, the electronic theodolite replaces the optical dial with a photoelectric scanning dial, and replaces the manual optical micrometer readings with automatic recording and display readings, which simplifies the angle measurement operation and avoids the generation of reading errors. It is called a total station because it can complete all the measurement work on the station once the instrument is installed. It is widely used in the fields of precision engineering measurement or deformation monitoring such as large-scale buildings above ground and underground tunnel construction.

Although the instruments are very advanced and accurate, if the supporting structure is unstable and not conducive to adjustment, it will also directly affect the accuracy of the measurement data. At the same time, since a large amount of measurement work is required from the early stage to the end of the civil engineering, and the base points of the measurement should be dispersed into many measurement points according to the needs, it is necessary to carry the instrument. Not only do you need to carry the instrument, but also the stand. The instrument is generally carried in a special bag, and the volume is not large, but the stand is relatively large, so its portability and stretchability are very important for carrying. At the same time, in view of the above The stability of the telescopic structure is also very critical.

In addition, since the surveyors still need to record after using the instrument to measure, the current on-site recording method cannot be separated from the paper recording requirements, the configuration cost of electronic equipment is too high, and the related system software is not very convenient, so the data The viewing and recording also need to be manually marked and recorded, which further increases the workload of the surveying and mapping personnel.
