Specific implementation mode
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It is said according to following
Bright, the purpose of this utility model, technical solution and advantage will be apparent from.It should be noted that described embodiment is this
The preferred embodiment of utility model, instead of all the embodiments.
In conjunction with shown in Fig. 1 and Fig. 2, a kind of real-time inspection and control system of diaphram wall, it include pre-buried steel lath 1,
Several hydraulic support devices 5, hydraulic control unit 8 and wall sidesway monitoring device.
The pre-buried steel lath 1 is uniformly embedded in diaphram wall 6, (in figure not with the steel reinforcement cage in diaphram wall
Indicate) it makes together, 1 place plane of the pre-buried steel lath is parallel to the metope of diaphram wall 6.Pre-buried steel lath according to
Design of foundation pit is embedded in diaphram wall designated position, and size is determined according to specific design of foundation pit, its effect is by steel branch
It supports increased axle power to be uniformly and effectively applied on diaphram wall, to preferably control foundation pit deformation；
5 top pressure of the hydraulic support device is on the metope at the embedded place of pre-buried steel lath 1.
The hydraulic control unit 8 is connected with each hydraulic support device 5 respectively by hydraulic tube 7, is realized to hydraulic pressure branch
The hydraulic control of support arrangement.
The wall sidesway monitoring device includes single mounted on the displacement meter 2 of each measurement point of diaphram wall and control centre
Member 4, between the displacement meter 2 and control centre's unit 4 and control centre's unit 4 passes through signal with hydraulic control unit 8
Line 3 connects.
Preferably, in order to by the axial force of the supports stepless action of hydraulic support device at top pressure metope, and it is continuous to underground
Wall plays the role of localised protection, is provided between the metope at the hydraulic support device 5 and its top pressure and reinforces backing plate 9.Institute
It states and reinforces the preferably steel plate of backing plate 9.Hydraulic support device acts on diaphram wall pre-buried steel lath position by reinforcing backing plate
Place is set, hydraulic pressure control can be passed through according to control centre's unit to the comparing result of diaphram wall sidesway monitoring data and setting value
Unit processed adjusts bracing members axle power size in real time, to balance diaphram wall sidesway caused by excavation stress.
In conjunction with Fig. 3, preferably, the hydraulic support device 5 is including bracing members 5a and passes through bolt 10 and steel branch
