Description

Technical Field

[0001] The invention relates to the technical field of remote grouting pressure monitoring devices, in particular to a remote grouting pressure monitoring device for a dark excavation tunnel face. Background Art

[0002] During the tunnel excavation process, the heading face needs to be grouting treated. The tunnel heading face is generally located deep underground, so a remote grouting control mechanism is needed to grout the heading face. In addition, the underground pressure will change during the grouting process, thereby increasing the grouting pressure. Increasing the grouting pressure will cause cracks in the ground. If there are buildings nearby, it will also cause damage to the buildings. Therefore, it is necessary to monitor the underground pressure during the grouting process.

[0003] Considering that the grouting pressure involves the face pressure and the internal pressure of the grouting machine during the grouting pressure monitoring process, and whether the face pressure is too high is mainly inferred by monitoring the pressure inside the grouting machine, the accuracy of the internal pressure of the grouting machine needs to be guaranteed. Therefore, some grouting pressure monitoring devices with special functions can be used.

[0004] Generally, the traditional grouting pressure monitoring device mainly affects the grouting pressure of the grouting machine by the reverse effect of the pressure of the face after grouting, and then infers whether the face pressure is too high. Once the grouting machine is blocked during this process, the internal pressure will rise rapidly, which can easily lead to misjudgment and mistakenly believe that the pressure is too high. At this time, if the pressure is controlled to drop, the pressure of the originally blocked pipe mouth will be insufficient, which will further aggravate the blockage and is very inconvenient.

[0005] In summary, it is necessary to propose a remote grouting pressure monitoring device for the face of a dark excavated tunnel to solve the above problems. Summary of the invention

At this time, the limiting screw 811 is rotated, so that the limiting screw 811 can be fixed with the limiting screw hole 89, and then the data connection line 14 can be limited;

[0082] When the mounting plate 10 needs to be supported on the ground for installation, the second screw rod 916 is rotated at this time, so that the second screw rod 916 can drive the first screw hole block 92 and the second screw hole block 93 to move, and then the L-shaped rod 95 can be driven to move upward, and the data connection line 14 located on one side of the mounting plate 10 is clamped into the wire clamping groove 97, and the round clamping rod 99 on the protective cover plate 910 is clamped into the round clamping hole 98.
