A kind of bridge hanging basket Deck curing control method, comprising the following steps:
S1 presets the safe preset value of cradle construction environment, including smokescope value and temperature value；
S2, A/D acquisition module acquire current smokescope value and temperature value, the smokescope value and temperature value of acquisition with
Preset value in PLC control module compares, and PLC control module issues trigger signal, alarm device alarm when exceeding preset value；
S3, spray system start automatically, and spray head sprays cooling medium.
Bridge construction is built by Hanging Basket equipment paragraph by paragraph pouring, during pouring maintenance bridge section, the temperature on mixed mud surface
Degree need to be strictly controlled, and the mixed mud pouring quality that temperature crosses relative superiority or inferiority is poor, and the anti-pressure ability of bridge pier in the future is insufficient, and mixed mud
Native internal the case where there are smokes, smoke amount show greatly internal temperature height, need to carry out cooling processing.
In step S1 in the present invention, by the way that detector is added in Hanging Basket equipment in the present embodiment, mixed mud is supported
The surface temperature of external temperature environment, mixed mud during shield and the smokescope value in existing smoke carry out
Detection is located at 2 top of bridge floor of maintenance on the couplet on the door 1 of Hanging Basket as shown in Fig. 2 and is provided with heat detector 3 and sense cigarette
Detector 4, heat detector 3 and smoke detector 4 respectively by A/D acquisition module complete data mode conversion after with PLC
Control module 7 connects；The smokescope value on the detection maintenance of smoke detector 3 road surface, and smokescope value signal is reached into PLC control
Molding block, similarly, the temperature value on the detection maintenance of smoke detector 4 road surface, and temperature value signal is reached into PLC control module.
In step S2, the signal that heat detector 3 and smoke detector 4 detect is after the judgement of PLC control module, output
It is connected to spray system 5 and alarm device 6, the output of heat detector 3 and smoke detector 4 respectively through PLC control module is adopted
With the relationship of logical "or", guarantee that heat detector 3 and smoke detector 4 can individually trigger spray system 5.
To ensure to conserve the quality on road surface, the preset operating temperature value of PLC control module is 50 degrees Celsius, smoke detector
4 preset smokescope values are 0.8ppm
The spray system 5, including storing the water tank 51 using water as cooling medium, the work for passing through piping connection with water tank 51
For the water pump 52 of the power source of liquid water flowing, the terminal of pipeline, which is sprayed, is provided with spray head 53 at direction face maintenance road surface,
The solenoid valve 54 with the output connection of PLC control module, the water are provided on the pipeline between spray head 53 and water pump 53
Pump 52 is connect with the output of PLC control module, also, an output port of water pump 52 and the total PLC control module of solenoid valve 54.It opens
When dynamic, heat detector 3 and smoke detector 4 trigger PLC control module and issue enabling signal, and enabling signal is transferred to water simultaneously
Pump 52 and solenoid valve 54, solenoid valve 54 act immediately, pipeline access, and water pump 53 starts, and the starting of water pump 53 generally requires 30~55
Safety problem is not present in the starting time of second, pipeline.
