Description
Technical field
The present invention relates to the technical field of geotechnical engineering, relate in particular to the technical field of base pit engineering wireless automatic monitoring warning system.
Background technology
Along with the development of urban construction, the cutting depth of foundation pit construction is more and more darker, develops into from initial 5～7 meters to have reached more than 20 meter the deeplyest the most at present.Because the complexity of underground soil mass property, loading condition, construction environment, the monitoring that soil body proterties, environment, adjacent structure, the underground installation that causes in work progress changed has become the requisite important step of engineering construction.By the various testing elements of in supporting and protection structure and ground, imbedding in advance, realize dynamic monitoring to excavation of foundation pit and underground construction process, become the important means that realizes safe construction and information-aided construction.The monitoring content of foundation ditch mainly contains: observation and soil pressure test etc. are pressed in the axial force test that the axial force test that supports in the deep horizontal displacement of top horizontal movement of supporting and protection structure wall and vertical displacement, supporting and protection structure, the concrete, steel pipe support, water-level observation, hole.
Traditional artificial observation method is because its observation time is long, and observation period and frequency limited system are measured and finished the back and limitations such as monitoring length reporting period occur, and can't satisfy growing rapid construction and improve constantly the requirement of operation maintenance efficient.At present China is also very backward aspect the foundation pit construction automated security monitor, particularly monitoring, control and network in conjunction with aspect very weak, also do not form stable, practical, the long distance control system reliably of a cover.
