Remote automatic monitoring system and method for pre-compaction treatment of soft soil foundation

Abstract

The invention provides a remote automatic monitoring system and method for pre-compaction treatment of a soft soil foundation, wherein the system comprises a monitoring sensor module, a field control center module and a remote control center module; the detection sensor module comprises a monitoring sensor module which comprises a plurality of automatic sensor groups; the field control center module comprises a plurality of smart measurement and control units and a field control center; the plurality of automatic sensor groups are connected with the corresponding smart measurement and control units, respectively; the smart measurement and control units are in communication connection with the field control center through an Internet of things or a wireless network; and the field control center is in wireless communication connection with the remote control center module. The remote automatic monitoring system provided by the invention is capable of setting up real-time data of formation consolidation key parameters, controlling the consolidation process development of the soil body immediately and controlling the construction quality, and also capable of finally evaluating the reinforcing efficiency and the reinforcing effect of the pre-compaction reinforcing method in Shanghai district, as a result, the measurement accuracy can be effectively improved, the interference of human factors can be avoided and the engineering field line network can be simplified.

Description

technical field [0001] The invention belongs to rock and soil monitoring methods, in particular to a remote automatic monitoring system and method for soft soil foundation preloading treatment. Background technique [0002] Most of Shanghai is located on soft soil foundations, and surcharge preloading method and vacuum preloading method are widely used for treating deep and thick soft foundations because of their advantages such as simple methods, low cost for large-area treatment, and simple equipment. Regardless of the surcharge preloading method or the vacuum preloading method, there is a process of transferring the preloading energy to the deep layer. The transfer process is essentially a process of energy attenuation, which affects the consolidation process of the deep soil. [0003] The soil parameters during the preloading process are an important basis for judging the effect of preloading, whether the construction is completed, and whether the pump can be stopped or ...

AI Technical Summary

Problems solved by technology

[0004] However, most of the monitoring methods currently used are ordinary manual traditional monitoring. Due to the limitations of construction technology and on-site machinery and other conditions, the traditional monitoring methods are more difficult to apply:

[0005] ①The influence of human factors is large, the measurement error is large, and the monitoring frequency is low, which cannot meet the requirements of high-precision measurement

[0006] ②It does not have real-time performance, and the manual general monitoring data has a lag, which is not conducive to project quality and safety monitoring

[0007] ③On-site measurement is labor-intensive and data processing is complicated, so it cannot form an automatic monitoring system

[0008] ④ Long-term operation monitoring is not possible, and the settlement and stability of the subgrade in the later stage of the project cannot be evaluated
