On reinforced concrete supports.
2) the every reinforced concrete that system, temperature sensing device in monitoring unit and displacement monitor will record is started
Temperature and end displacement data that soil supports are sent to monitor terminal.
If the displacement δ s of the reinforced concrete support end corresponding to a certain monitoring unitnLess than or equal to its permissible value [δ
sn], illustrate the foundation ditch displacement of position corresponding to this reinforced concrete support in span of control, the axle of reinforced concrete support
Power meets requirement.Now, control monitor terminal and simultaneously close off thermal source by switching device connection low-temperature receiver, utilize conduction device to conduct
Reinforced concrete support is lowered the temperature by low-temperature receiver, it is ensured that reinforced concrete support can apply stable support, especially all the time to foundation ditch
It is when temperature affects reinforced concrete support, reduces the temperature of reinforced concrete support, it is to avoid foundation pit deformation.
If the displacement δ s of the reinforced concrete support corresponding to a certain monitoring unitnMore than its permissible value [δ sn], explanation
Corresponding to this reinforced concrete support, the foundation ditch of position is located at outside span of control, the axle power of this root reinforced concrete support
Requirement cannot be met.Now, control monitor terminal and simultaneously close off low-temperature receiver by switching device connection thermal source, utilize conduction device to pass
Reinforced concrete support is heated by heat conduction source, improves the axle power of reinforced concrete support.
During heating increases axle power, set classification according to on-site actual situations and apply axle power, i.e. use fractional heating
Mode reinforced concrete support is heated, the reinforced concrete support end that monitor terminal is passed back according to displacement monitor
Position shifting parameter adjusts the conduction time of thermal source, i.e. heat time heating time.The axle power of reinforced concrete support all can be entered by heating every time
Row compensates, thus causes its end displacement to change, between degree and the displacement variable of reinforced concrete support end of heating
Just there is corresponding relation.Therefore, determine the degree of heating every time according to the displacement variable of reinforced concrete support end, from
And the classification realizing axle power applies, so, can avoid disposably being applied to the unstable factor that foundation ditch brings.
The displacement variable of reinforced concrete support end after axle power applies when setting heating every time, when heating reaches every time
During this displacement variable, heating stops；Reciprocal fractional heating according to this, until δ snLess than or equal to its permissible value [δ sn] and when stablizing
Stop heating.
3) temperature parameter passed back according to temperature sensing device, it is judged that the deformation of concrete support after intensification, if going out
Existing variations in temperature is relatively big and time change in displacement is the least, should check equipment, discharge fault.
Meanwhile, can judge according to the change in displacement of the temperature of reinforced concrete support combined with steel reinforced concrete supporting base end portion
Heating or the cooling impact on the axle power of concrete support, thus accurately control heating or the degree of cooling and position.
4) repeat the above steps 2)-3), the axle power of reinforced concrete support is monitored in real time and compensates.
It is arranged on the heat pipe 3 within reinforced concrete support 1 and conducting strip 4 at assembling reinforcement concrete support 1 reinforcing bar
While complete install, the remaining part in monitoring unit completes in concreting and treats that its intensity meets requirement, and foundation ditch is opened
After digging, it is installed on reinforced concrete support 1 by the structure of above-mentioned each monitoring unit, finally each monitoring unit is passed through
Wired or wireless mode is connected with monitor terminal.
Although design and the embodiment of this utility model purpose is elaborated by above example referring to the drawings,
But those skilled in the art will realize that under the precondition limiting scope without departing from claim, still may be used
This utility model is made various modifications and variations, such as: the concrete version of each parts, size, quantity etc., therefore
This repeats the most one by one.
