[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Referring to Figs. 1-3 The embodiment aims to provide a detachable settlement measuring marker, and detailed structures and functions are as follows.

[0025] The detachable settlement measuring marker mainly comprises a base 1, a marker body 2, a detachable nail 3 and a protective cover 4.

[0026] The base 1 is used for embedding in a preset position of a wall to be observed. The base 1 is internally provided with internal threads, which are designed to be threadedly connected to one end of the marker body 2. The outer surface of the base 1 is processed into a zigzag shape, which can increase the friction between the base 1 and the wall, so that the base 1 is more stably embedded in the wall. In addition, in the embodiment, the diameter of the base 1 is set to 25 mm, and the length is set to 50 mm.

[0027] One end of the marker body 2 is provided with external threads matched with the internal threads of the base 1, so that the marker body 2 can be firmly fixed on the base 1 through thread connection. The other end of the marker body 2 is provided with a marker ball head 21, which facilitates the observation personnel to intuitively observe the settlement data. An insertion hole is formed in the rod body of the marker body 2, and the insertion hole can be in the shape of a straight line, a cross, a pentagon or a hexagon, and can be a groove or a through hole. Such a design is to cooperate with the use of the detachable nail 3, so that the observation personnel can form a cross wrench by inserting the detachable nail 3 into the insertion hole, and then rotate the marker body 2 to realize the detachable connection with the base 1. In the embodiment, the length of the marker body 2 is 120 mm.

[0028] The detachable nail 3 is used to cooperate with the insertion hole on the marker body 2 to realize the dismounting operation of the marker body 2 and the base 1. The observation personnel only need to insert the detachable nail 3 into the insertion hole, and then rotate the detachable nail 3, so as to easily rotate the marker body 2 on or off the base 1.

[0029] In order to protect the base 1 from being eroded by the external environment, the embodiment further comprises a protective cover 4. The inner side of the protective cover 4 is provided with threads matched with the internal threads of the base 1, so that the protective cover 4 can be tightly covered on the base 1. In addition, the protective cover 4 is further provided with a second insertion hole matched with the detachable nail 3, and the axis of the second insertion hole is perpendicular to the axis of the protective cover 4, which makes it convenient for the observation personnel to install or dismount the protective cover 4. In order to reduce the number of specifications of the detachable nail 3, the hole diameters of the insertion hole and the second insertion hole are set to be the same. The protective cover 4, the base 1 and the marker body 2 are all made of stainless steel, which has the advantages of corrosion resistance, high strength and the like, and can ensure the long-term stable operation of the settlement measuring marker.

[0030] During installation, first, a hole is drilled in the wall, bridge pier or concrete structure to be observed at a predetermined position. The predetermined position is usually selected at a distance of 0.5 meters from the ground to ensure the representativeness of the measurement data. The diameter of the hole must match the diameter of the base 1 so that the base can be tightly embedded in the hole. For this purpose, a drill can be used to drill a hole slightly larger than the serrated outer periphery of the base so that the marble glue can be fully filled and solidified to enhance the bonding force between the base and the wall. It should be noted that the installation of the base 1 can also be based on the design drawings during the construction of the building or structure, and the base 1 is placed at the predetermined position and directly poured to become an integral part of the building, thereby making the marker more stable and solid.

[0031] Then, an appropriate amount of marble glue is applied to the serrated outer periphery of the base 1 to ensure a firm connection between the base 1 and the wall. Then, the base 1 is knocked into the hole to ensure that it is tightly bonded to the wall. Before the marble glue completely solidifies, avoid applying any external force to the base 1 to affect its solidification effect.

[0032] Under normal conditions, to protect the base 1 from damage, the protective cover 4 is tightened on the base 1. The protective cover 4 is designed to tightly fit the base to prevent debris from entering and clogging the base. When it is necessary to remove the protective cover 4 for settlement observation, only the disassembly nail 3 is inserted through the second insertion hole at the outer end to form a cross-shaped handle, which can be easily disassembled without tools.

[0033] When performing settlement observation, first, the protective cover 4 is removed, and then the disassembly nail 3 is inserted into the insertion hole in the middle of the marker body 2 to form a handle, so that the marker body 2 is fixed on the base 1 by threaded connection. After installation is complete, the bottom of the leveling staff is placed on the marker ball head 21 at the outer end of the marker body 2 to accurately measure the elevation of the marker point.

[0034] It is worth noting that when using this structure type marker, only one base 1 and protective cover 4 are needed for each monitoring point in the settlement project. The marker body 2 can be equipped as needed and installed flexibly according to the progress of field measurement. This not only saves costs but also improves measurement efficiency.

[0035] After observation is complete, the marker body 2 is rotated down from the base 1. To avoid clogging the base 1 with debris, the protective cover 4 should be rotated onto the base 1 after use. The entire process is simple and convenient, and the settlement measurement marker after installation is stable and reliable, which can intuitively reflect the settlement of the building and provide strong support for settlement monitoring work.
