Method and device for dynamically detecting foundation constraint capacity of civil engineering structure

Abstract

The invention belongs to the technical field of civil engineering, and discloses a civil engineering structure foundation constraint capacity dynamic detection method and device. The civil engineering structure foundation constraint capability dynamic detection device comprises a constraint force detection module, a bearing capacity test module, a density detection module, a data transmission module, a data processing module, a wireless communication module, a wireless base station and a cloud server. According to the invention, excessive bearing capacity data does not need to be processed through the bearing capacity test module, so that the data processing amount can be effectively simplified, and the burden of data processing is reduced; meanwhile, the foundation soil dry density obtained through the density detection module is small in error and high in accuracy rate, the detection method can obtain the result of one group of samples in a short time, data can be rapidly provided, site construction can be accurately guided, and the detection accuracy is high. The problems that a traditional foundation soil compactness detection method adopted in a construction site is large in detection frequency, low in detection speed and slow in detection result, and then the project progress is affected are solved.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a method for dynamically detecting the restraint capacity of a civil engineering structure foundation and a device method thereof. Background technique [0002] Civil Engineering is a general term for the science and technology of building various land engineering facilities. It refers not only to the applied materials, equipment and technical activities such as survey, design, construction, maintenance and repair, but also to the object of engineering construction. That is to say, various engineering facilities, such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, power stations, Airports, offshore platforms, water supply and drainage and protection works, etc. Civil engineering refers to the survey, planning, design, construction, installation and maintenance of various technical works such as surveying, planning, design, co...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the existing problems in the existing technology are: the existing dynamic detection method and device for the verification of the foundation bearing capacity of civil engineering structures need to test a variety of bearing capacity data, such as the bearing capacity of different positions, the average Bearing capacity, maximum bearing capacity, minimum bearing capacity, etc., only when the above bearing capacity data meet the corresponding required data, the bearing capacity of the rectangular foundation is considered to meet the bearing capacity requirements, the burden of data processing is relatively large, and the required consumption There may be more time and resources; at the same time, the existing dry density of foundation soil generally has the disadvantages of long detection time, low accuracy, complicated operation of instruments and equipment, and high detection cost. It takes at least 24 hours for the detection results to come out. When it came out, it was far behind the progress of the project. Even if it was found that the inspection indicators were not satisfied or there were problems, the on-site fill had already covered several layers, and it had no guiding significance for the engineering quality of the construction site.
