Description
Technical field
The utility model is related to Open caisson construction technology fields.More specifically, the utility model is related to one kind based on long-range
The large-scale well-sinking foundation construction real-time monitoring system of Radio Transmission Technology.
Background technology
Open caisson is the works of pit shaft shape, it is sunk after overcoming borehole wall frictional resistance by its own gravity with cutting the earth in well
To designed elevation, then passes through concrete sealing bottom and clog wellhole, become the basis of Bridge Pier or other structures object.
Open caisson construction monitors, and refers to being adopted to the data of open caisson itself and periphery structures during open caisson construction
The process of collection.Present open caisson construction monitors mostly by staff in certain construction speed, at the construction field (site) into pedestrian
Work acquires, then collected original data processing is become achievement, but such collecting method disadvantage has very much：
1, artificial collecting work amount is larger, and handles data and be easy error.
Since open caisson construction is related to the stress, water level, degree of disturbing to open caisson bottom and the borehole wall, the slope etc. of surrounding buildings
Etc. parameters acquisition, the number that either frequency acquisition still acquires is all very huge, and efficiency is low by the way of manually acquiring
It is very easy to mistake occur down and when handling data.
2, only have the data of acquisition time at that time, the other time data of section to have no way of inquiring, the continuous of data can not be grasped
Situation of change.
It is exactly that can only often find the data of acquisition time at that time, the number of other times section using the result manually acquired
It is searched from archive office according to needs, it is difficult to can be inquired in first time, and the result manually acquired can not be intuitively
Observe the consecutive variations situation of data.
3, real time monitoring and early warning be cannot achieve.
It calculates result due to manually acquiring there are certain lag from collecting, while the frequency manually acquired is not
Height, therefore construction personnel can not obtain monitoring result in real time, thus also just can not in time to the situation that is likely to occur in construction into
Row early warning.
