Description

Technical Field

[0001] The utility model relates to the technical field of bridge and tunnel detection, and more specifically, to a bridge and tunnel settlement observation device. Background Art

[0002] Traffic construction plays a very important leading role in the national economic development. In the construction of highways, railways and urban traffic, various structures such as bridges and tunnels need to be built to cross rivers, deep valleys and straits or cross mountains and underwater. Since bridges and tunnels are indispensable in traffic construction, it is necessary to observe the settlement of bridges and tunnels during the construction of bridges and tunnels in order to understand the settlement of bridges and tunnels. A settlement observation device for bridges and tunnels described in the publication number (CN129745270U) is used. By screwing the bolts, the bolts no longer fix the thick rods, and the embedded plates are filled into the roadbed of the bridge tunnel. After the construction of the bridge tunnel is completed, the sleeve is put on the thick rod, and the limit block will be located in the slide groove. At this time, the bottom plate fits the roadbed and plays a supporting role. The observation rod is screwed, and the observation rod will drive the threaded block to rotate in the threaded groove to squeeze the pressure plate. The pressure plate will squeeze the telescopic rod and the spring. A scale mark is set on the observation rod, and as the observation rod rotates.

[0003] However, when the above device is in use, the scale mark on the observation rod can be adjusted to facilitate the user to record the observation data, which can effectively avoid the rotation of the embedded plate and improve the accuracy of the observation data. It can also avoid the separation of the thick rod and the sleeve when not in use. However, the internal structure of the above device is relatively complicated, and when it is installed and used, the vehicle generates a lot of dust when driving inside the tunnel or bridge, and the dust can easily enter the inside of the sleeve, thereby affecting the sliding of the thick rod. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a bridge tunnel settlement observation device. The technical problem to be solved by the utility model is: how to prevent external dust from entering the interior of the observation device body and affecting the sliding stability of the limit sleeve and the observation marker rod and make adjustments.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bridge tunnel settlement observation device, comprising an observation device body, a square groove is provided on one side of the outer end surface of the observation device body, a limit sleeve is provided on the inner end of the observation device body, a threaded groove is provided in the middle of the upper end of the observation device body, a mounting rotating block is provided on the outside of the upper end of the observation device body, and a rotating dial is provided in the middle of the upper end of the mounting rotating block;

[0006] A rotating block is provided in the middle of the lower end of the rotating installation block, and an external thread is provided on the outer end face of the rotating block. A limited mounting groove is provided in the middle of the lower end of the rotating block, and a limited sliding block is provided inside the limited mounting groove. An observation marking rod is provided on the lower end face of the limited sliding block, and an L-shaped sliding block is provided on the upper side of the outer end face of the observation marking rod. A limited slot is provided on the inner end face of the thread groove at the upper end of the main body of the observation device.

[0007] In a preferred embodiment, a transparent observation plate is provided on the inner end surface of the square groove, and a first placement support plate is provided on the outer side of the lower end of the observation device body;

[0008] A second placement support plate is provided at the lower end of the limiting sliding sleeve, and a reinforcement support plate is provided at the upper end of the first placement support plate on the outside of the observation device body and at the upper end of the second placement support plate on the outside of the limiting sliding sleeve.

[0009] In a preferred embodiment, an observation marking rod is provided on the lower end surface of the limit slider, and the outer end surface of the first placement support plate in the top view direction is larger than the outer end surface of the second placement support plate in the top view direction;

[0010] The number of the reinforcement support plates is multiple, and they are arranged in a ring array outside the center points of the first placement support plate and the second placement support plate in the top view direction.

[0011] In a preferred embodiment, the inner end surface of the limit sleeve is matched with the outer end surface of the observation marking rod, the outer end surface of the observation marking rod is provided with a settlement height indication mark, and the upper side of the outer end surface of the limit sleeve is provided with an extended external thread;

[0012] The rotating clamping block is connected to the observation device body in a state where the external thread and the thread groove are correspondingly clamped, and the outer end surface of the limit sliding block is adapted to the inner end surface of the limit installation groove.

[0013] In a preferred embodiment, the number of the limit slots is two, and they are arranged in a mirror image state on both sides of the vertical central axis of the main body of the observation device in the top view direction;

[0014] The number of the L-shaped sliding blocks is two, and they are arranged in a mirror image state on both sides of the vertical central axis of the main viewing direction of the observation marking pole.

[0016] Technical effects and advantages of the utility model:

[0017] When the utility model is actually used, the corresponding setting state of the limit sleeve and the observation marker rod can facilitate the sliding of the limit sleeve on the outer end face of the observation marker rod, so that the height of the bridge and tunnel settlement can be accurately measured. At the same time, when the limit slot and the L-shaped slider are set in the corresponding state, the stability of the installation of the observation marker rod can be effectively increased to avoid the rotation and sliding of the observation marker rod, which makes it inconvenient to observe the punctuation points on the surface of the observation marker rod, thereby causing inconvenience to the observation of the bridge and tunnel settlement. At the same time, when the rotating block, the rotating dial plate, the external thread and the thread groove are installed in the corresponding state, the sealing of the interior of the observation device body can be effectively increased to avoid external dust from entering the interior and affecting the sliding effect between the limit sleeve and the observation marker rod.
