Description

Technical Field

[0001] The utility model relates to the technical field of secondary lining vault voiding, in particular to a tunnel secondary lining pouring monitoring device. Background Art

[0002] There are two solutions to the problem of secondary lining vault voids in the prior art. One is to use radar to detect after the final setting of the pouring is completed, and then inject grouting to fill the vault again; the other is a tunnel vault void alarm system, which uses four sensors arranged in a continuous manner in the longitudinal direction of the vault. When the concrete pouring reaches the top, the sensor alarm is triggered to determine whether the vault concrete is poured full.

[0003] However, radar detection technology is used to detect vault voids only after the secondary lining has been cast and finally set. The grouting measures taken are time-consuming and labor-intensive. Excessive voids may even lead to the dismantling of the first mold and the second lining, and the solution to the vault voids is not timely. The tunnel vault void alarm system is too expensive and is directly left in the secondary lining concrete after use, which has a certain impact on the integrity of the secondary lining concrete. Utility Model Content

When leakage is found, concrete can be supplemented immediately. The cost is low, and the observed materials can be withdrawn from the secondary lining, ensuring the integrity of the secondary lining. It solves the problems in the prior art that the radar detection technology grouting measures are time-consuming and labor-intensive, and the timeliness is poor, and the tunnel vault de-airing alarm system is too expensive, which has a certain impact on the integrity of the secondary lining concrete.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The radar detection technology in the prior art performs vault void detection only after the secondary lining is poured and finally set. The grouting measures taken are time-consuming and labor-intensive. Excessive voids may even lead to the removal and redoing of the first mold and the second lining. The solution to the vault void is not timely. The cost of the tunnel vault void alarm system is too high, and it is directly left in the secondary lining concrete after use, which has a certain impact on the integrity of the secondary lining concrete. The following describes a tunnel secondary lining pouring monitoring device provided by some embodiments of the utility model in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] In order to monitor the pouring process of the tunnel secondary lining in real time, so as to timely supplement the concrete bonding Figure 1 , Figure 2 and Figure 3As shown, a tunnel secondary lining pouring monitoring device is proposed, wherein a fixing mechanism 1 serves as the device body, and a monitoring mechanism 2 is arranged at one end of the fixing mechanism 1, through which the monitoring mechanism 2 is used to monitor the concrete pouring process in real time, and an adjusting mechanism 3 is arranged on the monitoring mechanism 2, through which the adjusting mechanism 3 is used to simply adjust the monitoring angle of the monitoring mechanism 2, so that the staff can monitor the concrete pouring process more comprehensively.

[0026] In order to avoid the situation where the workers rely on experience alone to judge, resulting in the second lining vault being emptied, a more direct and more real-time observable adjustment mechanism 3 is proposed. The adjustment mechanism 3 is provided with a fixed ring a301 and a fixed ring b302. The fixed ring a301 and the fixed ring b302 are respectively fixedly connected with a pull rope a303 and a pull rope b304. Two limit blocks a306 are fixedly connected to the middle part of the outer tube 101, and two limit blocks b307 are fixedly connected to the outer tube 101 near the port. One end of the outer tube 101 is equipped with a pull rope for pulling. The clamp block 305 for fixing the rope a303 and the pull rope b304 is symmetrically arranged in the connecting shell 102. The pull rope a303 is fixedly connected to the pull ring a at one end connected to the outside of the outer tube 101, and the pull rope b304 is fixedly connected to the pull ring b at one end connected to the outside of the outer tube 101. The fixing ring a301 and the fixing ring b302 are both fixedly connected to one side of the casing 202. The fixing ring a301 and the fixing ring b302 are symmetrically located above and below one side of the casing 202. The pull rope a303 is fixedly connected to the pull rope a303 through the pull ring a and the pull ring b. The casing 202 rotates with the rotating rod 201 under the action of the fixing ring a301 and the fixing ring b302, and the moving paths of the pulling ropes a303 and b304 are restricted by the two limiting blocks a306 and the two limiting blocks b307. When the staff needs to fix the pulling length of the pulling ropes a303 and b304, the clamping block 305 is clamped with one end connected to the outer tube 101 to fix the pulling ropes a303 and b304, so that the staff can fix the pulling ropes a303 and b304. The recording direction of the camera 203 is easily controlled, so as to monitor the internal pouring process in all directions, reduce the situation where workers rely on experience to judge, resulting in the second lining vault being hollowed out, and greatly reduce the hollowing rate of the second lining vault. Compared with the radar detection method, it is more real-time, and when the void is found, the concrete is immediately supplemented to avoid spending a lot of money, manpower and time on grouting after the final setting of the second lining, thereby reducing costs and increasing efficiency. Compared with the tunnel vault hollowing alarm system, the construction cost is greatly reduced, and the required observation materials can be removed from the second lining, ensuring the integrity of the second lining.

[0027] The fixing mechanism 1 includes a connecting outer tube 101 and a connecting outer shell 102, and the monitoring mechanism 2 includes a rotating rod 201 rotatably connected to the inside of the connecting outer shell 102, and a casing 202 is fixedly connected to the rotating rod 201, and a camera 203 is installed in the casing 202. The position of the rotating rod 201 is fixed by the connecting outer shell 102, and the angle of the camera 203 can be adjusted following the rotating rod 201 through the casing 202, thereby ensuring the monitoring effect.

[0028] Embodiment 2:

[0029] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problems in the prior art that the radar detection technology grouting measures are time-consuming and labor-intensive, have poor timeliness, the tunnel vault de-airing alarm system is too expensive, and has a certain impact on the integrity of the secondary lining concrete. However, when the camera 203 records the pouring process, dust may be generated inside the tunnel secondary lining during the pouring process, thereby affecting the clarity of the picture recorded by the camera 203.

[0030] In order to ensure the clarity of the picture during the pouring process, Figure 1-Figure 4 As shown, a cleaning component 308 is proposed for easily cleaning the surface of the camera 203. The cleaning component 308 is connected to an arc-shaped fixing plate 3081 fixedly on the inner side of the connecting shell 102. An arc-shaped groove 3082 is provided on one side of the arc-shaped fixing plate 3081. An arc-shaped clamping plate 3083 is clamped in the arc-shaped groove 3082. A connecting frame 3084 is fixedly connected to one side of the bottom of the arc-shaped clamping plate 3083. An arc-shaped connecting plate 3085 is fixedly connected to one side of the connecting frame 3084. A cleaning cotton 3086 is detachably installed on one side of the arc-shaped connecting plate 3085. The arc-shaped clamping plate 3083 is clamped and fixed by the arc-shaped groove 3082 on the arc-shaped fixing plate 3081, and the arc-shaped connecting plate 3085 is fixed by the connecting frame 3084. The radius of the arc-shaped connecting plate 3085 is slightly larger than the rotation radius of the housing 202. Therefore, when the staff rotates the camera 203 90° through the pull rope a303 or the pull rope b304, the cleaning cotton 3086 on the arc-shaped connecting plate 3085 will be tightly attached to the surface of the camera 203, so that the camera 203 can be easily cleaned and the clarity of the monitoring image is ensured.

[0031] A circular hole a and a circular hole b are respectively provided on the two limit blocks a306 and the two limit blocks b307. The pull rope a303 passes through the circular hole a and the circular hole b on one side in turn, and the pull rope b304 passes through the circular hole a and the circular hole b on the other side in turn, so as to avoid the entanglement of the pull ropes a303 and b304 during the control process of the staff, thereby ensuring the adjustment effect of the device.

[0032] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
