The attemperator 5 of device 4 periphery and be arranged on the displacement monitoring between reinforced concrete support 1 and reinforced concrete fortifield village purlin 7
Device 6；Wherein temp sensor device 2 measures the temperature of reinforced concrete support 1, heat-transfer device 3 for adding in real time
The even heat of thermal 4 is delivered on reinforced concrete support 1, and heater 4 is for adding reinforced concrete support 1
Heat, attemperator 5 is for being incubated reinforced concrete support 1, and displacement monitor 6 monitors armored concrete in real time
Support the displacement of 1.Generally speaking, the device of external monitoring unit is arranged at the periphery of reinforced concrete support 1, and it adds
Heat is to heat from outside to reinforced concrete support 1.
Embodiment two: as shown in Figure 5 and Figure 6, the present embodiment is compared to the difference of embodiment one: the present embodiment
Using built-in monitoring unit, wherein heat-transfer device 3, heater 4 are arranged at the inside of reinforced concrete support 1,
It is accomplished that and heats from inside to reinforced concrete support 1.Specifically, heat-transfer device 3 is fixedly installed on reinforced concrete
Soil supports on the reinforcing bar of 1, and heater 4 is fixedly installed on the periphery of heat-transfer device 3.
Embodiment three: as shown in Figure 7 and Figure 8, the present embodiment is compared to the difference of embodiment one, two: this reality
Executing example and use inside and outside combination type monitoring unit, it is built-in monitoring unit and the combination of external monitoring unit, it is achieved
Be reinforced concrete support 1 to be heated from internal, outside simultaneously.Specifically, within reinforced concrete support 1
It is fixedly installed a set of heat-transfer device 3 and heater 4 with reference to built-in monitoring unit on reinforcing bar, and at reinforced concrete support
The periphery of 1 is then fixedly installed a set of heat-transfer device 3 and heater 4 with reference to external monitoring unit, so, by interior
The heat-transfer device 3 in portion and heater 4 realize reinforced concrete support 1 carries out internal heating from inside, are led by outside
Thermal 3 and heater 4 realize carrying out reinforced concrete support 1 from outside external heat, improve heats, same to phase
For external or built-in monitoring unit, the heating to reinforced concrete support 1 is more uniform.
When above-described embodiment is embodied as:
Heat-transfer device 3 includes but not limited to rectangular slab or the tubulose being made up of Heat Conduction Materials such as iron sheet, aluminum skins, by fixing
Element is wrapped in the periphery of reinforced concrete support 1 or is placed in the inside of reinforced concrete support 1 and along armored concrete
Support the elongated layout in support direction of 1.
Heater 4 includes but not limited to the resistance wire that the materials such as nickel chromium triangle are made, and resistance wire can uniform winding fill in heat conduction
Put outside 3 and along the elongated layout in support direction of reinforced concrete support 1, it is ensured that being heated evenly of reinforced concrete support 1.
Attemperator 5 includes but not limited to the heat-insulation layer that the material such as glass fibre, asbestos is made, and is wrapped up by retaining element
At the circumferential periphery of reinforced concrete support 1 and support the elongated layout in direction along it, layer parcel should be added at node and mix along reinforcing bar
Solidifying soil contact bar direction development length is not less than 1.0m, it is ensured that the heat insulation function of attemperator at node.
In conjunction with Fig. 1 and Fig. 2, the axle force compensating device in above-described embodiment has a following compensation process:
1) set up said system, and each device relevant to reinforced concrete support in system is respectively provided to every steel
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 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, and now heater is off work.
If the displacement δ s of the reinforced concrete support end corresponding to a certain monitoring unitnMore than its permissible value [δ sn],
Illustrate that corresponding to this reinforced concrete support, the foundation ditch of position is located at outside span of control, this root reinforced concrete support
Axle power cannot meet requirement.Now, being opened by switching device by controlling terminal, switching device controls heater and works to steel
Reinforced concrete supports and heats.
Axle power sets classification according to on-site actual situations and applies, and i.e. uses the mode of fractional heating to reinforced concrete support
Heating, monitor terminal adjusts switching device according to the displacement parameter that displacement monitor is passed back and opens and closes heater
Time.The axle power of reinforced concrete support all can be compensated by heating every time, thus causes reinforced concrete support end
Change in displacement, just there is corresponding relation between degree and the displacement variable of reinforced concrete support end of heating.Therefore,
Displacement variable according to reinforced concrete support end determines the degree of heating every time, thus the classification realizing axle power is executed
Add, 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 sentence according to the displacement variable of the temperature of reinforced concrete support combined with steel reinforced concrete supporting base end portion
The disconnected heating impact on the axle power of concrete support, thus accurately control degree of heat and heating location.
4) repeat the above steps 2)-3), the axle power of reinforced concrete support is monitored in real time and compensates.
When using built-in monitoring unit or inside and outside combination type monitoring unit, it is arranged on reinforced concrete support 1 internal
Heat-transfer device 3 and heater 4 complete to install while assembling reinforcement concrete support 1 reinforcing bar, its in monitoring unit
Remaining part part completes in concreting and treats that its intensity meets requirement, after excavation of foundation pit, by the knot of above-mentioned each monitoring unit
Structure is installed on reinforced concrete support 1, finally by each monitoring unit by the way of wired or wireless with monitor terminal phase
Connect.
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.
