Description
Technical field
The utility model relates to tunnel deformation monitoring field, is specifically related to a kind of tunnel convergence deformation monitoring device.
Background technology
Convergence gauge is the instrument of the convergent deformation monitoring after being widely used in tunnel excavation at present.The convergence measuring point that ordinary convergence meter needs cooperation to be anchored at tunnel week could measure the relative displacement between Wall Rock of Tunnel two point of fixity, judges deformation tendency and the stability of country rock with this.The typical attachment method of convergence gauge as shown in Figure 1, as shown in Figure 1, convergence gauge carries two hooks, one is the steel ruler hook that can stretch, another is mounted in the fixed hook of the convergence gauge other end, by arranging convergence measuring point A, convergence measuring point B and convergence measuring point C (convergence measuring point is anchored in the Zhou Yanti of hole) on tunnel inner wall top and both sides, two of convergence gauge hooks are connected with the annulus on convergence measuring point respectively, just can measure relative displacement between two anchor points by convergence gauge.Two hooks at convergence gauge two ends need to be connected with the annulus on convergence measuring point respectively just can measure, and when convergence gauge only needs to be fixed on A point and C point, operation is very convenient, but when needing to be fixed to B point, just very difficult.On the one hand, due in order to ensure measuring accuracy, it is smaller that the annulus on convergence measuring point does, when restraining measuring point distance bottom surface and being higher, be difficult to hook to hang up annulus, now need to set up stand or ladder just can be installed, therefore belong to work high above the ground and there is certain risk; And Convergence monitoring generally carries out in the construction time, site operation cross-operation impact is large, and actual enforcement is very difficult.On the other hand, when restraining measuring point and being in higher position, due to people and measuring point spacing far, and measuring point itself is very little, add that in hole, light condition is very poor, therefore survey crew needs to spend a lot of time to go for point, takes aim at and could be suspended on annulus by hook, particularly, tunnel that barrel is long large for footpath, hole, and this shortcoming is especially obvious.Above shortcoming is all that the personnel by having wide experience just can overcome usually, but there is the problems such as enforcement speed is slow, success ratio is not high, installation quality is poor equally.In addition, after convergence measuring point is installed at present, some exposes tunnel wall, easily destroyed by external factors such as vehicles in blasting broken stone, hole, and current convergence measuring point can not carry out angular setting, can affect measuring accuracy.
Utility model content
The utility model aims to provide a kind of tunnel convergence deformation monitoring device, to solve the problem such as operating difficulties, potential safety hazard is large, speed is slow, success ratio is low, installation quality is poor, rapid wear existing when existing tunnel convergent deformation is monitored.
The utility model is achieved by following technical solution:
A kind of tunnel convergence deformation monitoring device, comprise reflective absorption measuring point and bindiny mechanism, reflective absorption measuring point comprises the base that bottom surface is provided with reflecting coating, and base top middle portion is connected with tapered thread anchor pole; Bindiny mechanism comprises magnet base, and magnet base top is provided with column by screw thread, and column top is connected with universal joint, and the universal joint other end is connected with connecting rod, and connecting rod end is connected with annulus.
Described base thickness is 10mm, and its area > magnet base floorage.
Described magnet base outside is provided with switch.
The material of described base is stainless steel.
The beneficial effects of the utility model are:
Compared with prior art, the tunnel convergence deformation monitoring device that the utility model provides has the following advantages:
1) bottom surface of exposing of the utility model convergence measuring point scribbles reflecting coating, therefore in tunnel, under the low light level or dark surrounds, can find the position of convergence measuring point fast and accurately;
2) the utility model convergence measuring point is secured entirely in tunnel week ground, therefore there is not the possibility destroyed by external factor, plays a very good protection to measuring point;
3) convergence gauge is fixedly connected with reflective absorption measuring point by the adsorption magnetic force that the utility model is provided by magnet base, and bindiny mechanism just can link up with convergence gauge to be connected before fixing, therefore connected mode is very convenient, quick, improve work efficiency and difficulty action accomplishment, effectively prevent because space is little, distance and not easily hang up hook and the problem such as work high above the ground is dangerous;
4) bindiny mechanism of the present utility model is with universal joint, therefore can carry out the adjustment of angle to the installation of convergence gauge, improve measuring accuracy;
5) bindiny mechanism is namely recoverable after being finished, and carries annulus and link up with most of convergence gauge and all can be connected, therefore have can reuse, service time is long, applicability is wide feature;
6) the reflective absorption measuring point of the utility model and bindiny mechanism's structure are simple, easy processing and fabricating and cost of manufacture is low.
