Abstract
The invention relates to a monitoring technology for soft ground treatment engineering and in particular relates to an automatic intelligent vacuum preloading monitoring system. The automatic intelligent vacuum preloading monitoring system comprises a monitoring sensing unit, an automatic control unit, a remote transmission unit and a monitoring terminal unit. The automatic intelligent vacuum preloading monitoring system can continuously monitor vacuum preloading construction in real time and remotely monitor working states of all sets of vacuumizing equipment in the whole vacuum preloading construction region and all vacuum negative pressure and pore water pressure monitoring points in real time, and therefore, the monitoring effect and the monitoring efficiency can be obviously improved, and the monitoring cost can be obviously reduced.
Description
Technical field
The present invention relates to the monitoring technology of soft foundation processing engineering, especially vacuum preloading automatic intelligent monitoring system.
Background technology
Vacuum preloading is the main construction of soft foundation processing engineering construction, and market application is more and more general.For ensureing the soft foundation processing construction effect of vacuum preloading, the construction requirement of vacuum preloading carries out 30-120 days vacuumize continuously and discharging consolidation construction operation to vacuum preloading soft foundation processing region maintaining under 80kpa vacuum negative pressure condition under vacuum seal film, therefore the process of vacuum preloading construction is carried out to lasting Real-Time Monitoring extremely important.
The Real-Time Monitoring of vacuum preloading construction process comprises to the monitoring of vaccum-pumping equipment duty, to the monitoring of vacuumizing effect and the monitoring to discharging consolidation effect, to the monitoring of vaccum-pumping equipment duty require vaccum-pumping equipment in 30-120 days 24 hours every days all in normal duty, to the monitoring of vacuumizing effect, require the vacuum negative pressure under diaphragm seal during vacuum preloading soft foundation processing to reach 80kpa, the monitoring of discharging consolidation effect is required to understand to the situation of change of soil body pore water pressure.
Because the construction area area of vacuum preloading construction is large; vaccum-pumping equipment quantity is many, layout dispersion and uninterruptedly operation for a long time; existing monitoring method and monitoring technology are to estimate by the mode of artificial inspection start or the stopped status of understanding vaccum-pumping equipment; by bury the mode of mechanical type vacuum meter and artificial inspection underground in vacuum preloading soft foundation processing region, estimate the vacuum negative pressure of understanding under diaphragm seal, by the mode of temporary construction opening gap WG, understand pore water pressure situation.The existing requirement that can not reach lasting Real-Time Monitoring to the monitoring method of vacuum preloading construction and monitoring technology, monitoring result is affected by human factors greatly, monitoring inefficiency, monitoring cost is high.
In Construction practices, unit in charge of construction often takes to bribe owner, management, over contract side's field supervisor or takes advantage of field supervisor and when building-site, do not close down especially at night all or part of vaccum-pumping equipment to save construction cost, and take artificial mode to destroy the internal construction of vacuum meter after mechanical type vacuum meter is installed in verification, the pointer of vacuum meter is navigated to 80kpa to manufacture false vacuumizing effect.
In order to overcome that can not realizing of the monitoring method of existing vacuum preloading construction and monitoring technology continues Real-Time Monitoring and in the deficiency aspect monitoring effect, monitoring efficiency, monitoring cost, technical scheme disclosed by the invention has adopted sensing, control automatically, remote transmission and system integration technology, realized the automation of vacuum preloading construction and intelligent monitoring, filled up the technological gap of domestic market in the automatic intelligent monitoring technical field of vacuum preloading construction.
