Technical Field
[0001] This invention relates to a device and method for continuously observing the uneven settlement on both sides of a connecting corridor of a high-rise building. It belongs to the field of building inspection technology and specifically relates to an observation device that can automatically monitor the settlement difference between the buildings on both sides of the connecting corridor in real time, avoiding the trouble and lag of manual monitoring. Background Technology
[0002] For high-rise buildings, underground construction, unevenness of the foundation over a large area, excessive extraction of groundwater and brine, and the continuous effects of heavy pressure and low load on the high-rise building can all cause ground settlement. Uniform settlement generally poses less harm to the building, but excessive settlement can lower the building's elevation and affect its usability. Uneven settlement is more harmful to the building, causing additional stress that can lead to cracks and even the fracture of local components, endangering the building's safety. This is especially true when there is a difference in settlement between the two sides of the building. After installation, connecting corridors must ensure that stress and strain are controllable to avoid settlement differences. The installation of the connecting corridor can lead to uncontrollable stress and strain on both sides, resulting in damage. Therefore, during the installation of the connecting corridor, it is necessary to ensure that the overall settlement difference between the two buildings is controlled within the error range. For high-rise buildings with elevated connecting corridors, considering that the external environment of the two buildings is different due to their different orientations, including differences in ground stability, groundwater content, and gravity load on both sides, there is a high possibility of uneven settlement between the two buildings. When uneven settlement occurs on both sides of the connecting corridor of a high-rise building, timely detection and diagnosis are required to prevent accidents caused by overall building instability. Summary of the Invention

[0011] The difference between this embodiment and Embodiment 1 is that: the observation protective cylinder is provided with a set of anti-collision strips, which consist of multiple anti-collision strips. These multiple anti-collision strips are equidistantly distributed along the circumference of the observation protective cylinder wall. The anti-collision strips have an arc-shaped structure, and their thickness gradually decreases from the middle to both ends. In use, the anti-collision strips can provide secondary protection for the observation protective cylinder, increasing its robustness and preventing it from being easily damaged by external forces. Example 3
[0012] The difference between this embodiment and Embodiment 1 is that: the observation protective cylinder has a protective groove, which is a ring structure. The protective groove is close to the opening of the observation protective cylinder, and the width of the protective groove gradually increases from the bottom to the opening. A set of indicator lights is built into the protective groove, and the set of indicator lights consists of multiple indicator lights located at the bottom of the protective groove. The multiple indicator lights are equidistantly distributed along the circumference of the bottom of the protective groove. In use, the indicator lights can remind passing personnel to avoid the device and prevent damage. At the same time, the protective groove can protect the indicator lights and prevent them from being damaged, going out, or losing their function. The observation protection cylinder has a cylindrical structure, and its diameter gradually increases in an arc shape from the opening to the bottom. This design increases the contact area between the observation protection cylinder and the building base plate, making the installation more secure and stable, and preventing it from easily loosening or falling off, thus affecting the accuracy of the observation results. The design of having multiple water passages equidistantly distributed around the circumference of the observation protective cylinder near the bottom of the cylinder allows for timely drainage of water when it is stored in the cylinder, preventing damage to the laser rangefinder from prolonged immersion. The edge of the observation support plate is located below the water passage hole. The design of the observation support plate extending horizontally from the middle to the edge and then diagonally downward to the edge allows the accumulated water to be discharged in time before it reaches the laser rangefinder, preventing the laser rangefinder from being damaged by long-term immersion. The design of the laser rangefinder being located on the reverse extension line of the center line of the observation isolation cylinder allows the laser emitted by the laser rangefinder to hit the observation target plate to observe the height of the target plate, thereby observing the building settlement difference. The conical protective cylinder is located near the bottom of the observation isolation cylinder. The diameter of the conical protective cylinder gradually decreases from one end near the bottom of the observation isolation cylinder to the other end. This design can block debris falling into the observation isolation cylinder and prevent debris from falling and damaging the laser rangefinder, thus preventing it from properly observing the building settlement difference. The conical protective fence is located near the opening of the observation isolation cylinder and is situated above the conical protective cylinder. The conical protective fence is designed with a conical structure to work with the conical protective cylinder to block debris falling into the observation isolation cylinder, preventing debris from falling and damaging the laser rangefinder and thus preventing it from properly observing the building settlement difference. The goal is to achieve real-time automatic monitoring of the settlement difference between the buildings on both sides of the connecting corridor using a laser rangefinder and observation markers, thus avoiding the inconvenience and delays of manual monitoring.
[0013] It should be noted that, unless otherwise explicitly specified and limited, the terms "placed," "connected," and "linked" should be interpreted broadly. For example, they can refer to fixed connections such as folded edges, rivets, pins, adhesives, and welds; detachable connections such as threaded connections, snap-fit connections, and hinges; integral connections; electrical connections; direct connections; or indirect connections via an intermediate medium; or internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.
[0014] It should be further noted that, in order to keep the description simple and clear, the above specific embodiments only describe the differences between them and other embodiments. However, those skilled in the art should know that the above specific embodiments are also independent technical solutions.
