It needs that the axle power of bracing members is adjusted, then main control unit 110 controls solenoid valve 123 and opens, and controls hydraulic pump to phase
The compensating hydraulic cylinder 122 answered is depressurized, and when detecting pressure value lower than the second preset pressure value, then stops hydraulic station 121
Compensating hydraulic cylinder 122 is depressurized, solenoid valve 123 is closed；The axle power of bracing members can be carried out according to the deformation situation of bracing members
It adjusts, it is ensured that engineering construction does not interfere with the safety of subway tunnel, surrounding building, effectively control surface subsidence, strict control
Situations such as foundation pit enclosure structure deforms；Supervise compensating hydraulic cylinder in real time by rangefinder 132 and level meter 133 simultaneously
Control is changed, the axis for the compensating hydraulic cylinder that rangefinder 132 is obtained by the wheelbase that rangefinder 132 is monitored compensating hydraulic cylinder
Main control unit 110 is sent in real time away from numerical value, when main control unit 110 judges that the wheelbase numerical value received is more than or lower than default
When wheelbase numberical range, then main control unit 110 issues alarm；The horizontal variation of compensating hydraulic cylinder is detected by level meter 133,
The horizontal values that level meter 133 passes through the compensating hydraulic cylinder that will acquire are sent to main control unit 110, when main control unit 110 judges
When the horizontal values received are more than or are lower than preset level numberical range, then the 110 yuan of sendings alarms of main control list, work as compensation
When the position of hydraulic cylinder changes, personnel in work can be made to make a response in time.
Please refer to figs. 2 and 3, in the present embodiment, the fluid pressure line between compensating hydraulic cylinder 122 and hydraulic station 121
When fracture, 122 decompression of compensating hydraulic cylinder will cause, and 122 decompression of compensating hydraulic cylinder, bracing members are unable to get effective support,
It is be easy to cause the deformation of surrounding enviroment, in order to avoid 122 decompression of compensating hydraulic cylinder causes significant impact, the compensation to bracing members
