Abstract
The utility model relates to a tunnel crossing construction disturbance grading early warning system in a power tunnel. The tunnel crossing construction disturbance grading early warning system comprises a displacement sensor, a display unit, a processing unit, a value setting unit and a warning unit, the displacement sensor is mounted on the top of the tunnel and used for detecting displacement information of a detected position, the display unit is used for displaying the displacement information, the processing unit is used for forecasting the displacement information of the top of the tunnel and judging a safe state of the top of the tunnel, the value setting unit sets the information, the warning unit is used for giving an alarm for the displacement information and/or a dangerous state, and the processing unit is respectively connected with the displacement sensor, the display unit, the value setting unit and the warning unit. Compared with the prior art, the tunnel crossing construction disturbance grading early warning system has the advantages of convenience, instantaneity, accuracy, reliability and the like.
Description
Technical field
The utility model relates to a kind of cable and uses support, especially relates to a kind of electric power tunnel and passes through constructing tunnel disturbance grading forewarning system system.
Background technology
Along with the carrying out of China's infrastructure, the underground construction of every profession and trades such as water conservancy, traffic, mine, building is just in the ascendant.Especially the high speed development of the construction of subway all cable need be installed in the tunnel under a lot of situation, and situation is complicated in the tunnel, especially being in complex geological conditions such as zone of fracture and weak band, the landslide accident takes place easily.Shield machine is installed the displacement monitoring on ground and the forecast of landslide seems extremely important to it in without the soft soil layer of reinforcing closely in the traversing operation during subway tunnel.Traditional displacement generally removes to read displacement data through manual regular; Analyze by the technician then; The possibility of on the one hand abominable geological conditions and landslide has very big danger for reading the survey personnel, and the poem of data is got with analysis and had certain hysteresis quality on the other hand.The problems referred to above are unfavorable for guaranteeing tunnel and personnel's safety, cause the accident easily.
Summary of the invention
The purpose of the utility model is exactly to provide a kind of convenience immediately, electric power tunnel passes through constructing tunnel disturbance grading forewarning system system accurately and reliably in order to overcome the defective that above-mentioned prior art exists.
The purpose of the utility model can realize through following technical scheme: a kind of electric power tunnel passes through constructing tunnel disturbance grading forewarning system system, it is characterized in that, comprising:
Be installed in the displacement transducer that tunnel top detects detection position top offset information,
Be used to show the display unit of displacement information,
Be used for processing unit that the tunnel top displacement information is predicted and its safe condition is judged,
The setting value unit of set information,
Be used for caution unit to displacement information and/or precarious position warning;
Described processing unit connects displacement transducer respectively, display unit, setting value unit and caution unit.
Described displacement transducer is through signal transmitting device connection processing unit.
Described caution unit comprises language output unit and warning lamp output unit.
Compared with prior art, the utility model can detect tunnel internal strain data by automatic on-line, and through deformation data is analyzed and calculated, realizes online automatic monitoring forecast, and reaction is instant, accurately and reliably.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment 1
As shown in Figure 1, a kind of electric power tunnel passes through constructing tunnel disturbance grading forewarning system system, comprising:

Be used to show the display unit 5 of displacement information,
Be used for processing unit 3 that the tunnel top displacement information is predicted and its safe condition is judged,
The setting value unit 4 of set information,
Be used for the caution unit to displacement information and/or precarious position warning, the caution unit comprises language output unit 6 and warning lamp output unit 7;
Described processing unit connects displacement transducer respectively, display unit 5, setting value unit 4 and caution unit.Described displacement transducer 1 is through signal transmitting device 2 connection processing unit 3.
Shield machine in without the soft soil layer of reinforcing closely in the traversing operation during subway tunnel line security normally run requirement:
The horizontal discrepancy in elevation≤the 2mm of two tracks in a, the tunnel
B, rail are to deviation and difference of height＜2mm/10m (being lateral variation sedimentation＜1.4 ‰)
C, malformation control require: vertical sedimentation of tunnel structure and protuberance≤± 5mm
D, the displacement of tunnel structure vertical equity :≤± 5mm
E, tunnel convergence value＜20mm
Report to the police when monitor value surpasses total deformation 1/2, and take emergency measures.
