Description

Technical Field

[0001] The utility model relates to the technical field of caisson construction, in particular to a monitoring device for measuring the overall inclination of a caisson. Background Art

[0002] Caisson structures can effectively utilize underground space and reduce floor space, and have great potential in the development of urban underground space. As the diameter and depth of the caisson increase, the volume and weight of the assembled caisson increase significantly. Once the caisson tilts during sinking, it will bring great construction difficulties to the project.

[0003] Traditionally, caisson sinking is mainly measured by placing an inclinometer tube on the inner wall of the caisson. The measurement result is the inclination at a point on the caisson side wall, and the overall inclination of the caisson cannot be accurately measured.

[0004] Therefore, a device that can effectively measure the inclination of caisson is needed to solve the above problems. Summary of the invention

[0005] The purpose of the utility model is to provide a monitoring device for measuring the overall inclination of a caisson based on the above-mentioned deficiencies of the prior art. The monitoring device is implemented by buckling a ring-shaped transparent box body on the top of the caisson and calculating the inclination of the caisson by the angle between the liquid surface in the transparent box body and the horizontal scale.

[0006] The purpose of this utility model is achieved by the following technical solutions:

[0007] A monitoring device for measuring the overall inclination of a caisson, characterized in that the monitoring device comprises a transparent box body and water filled in the transparent box body, the transparent box body is detachably mounted on the top of the caisson pipe segment via a fixing device, and a horizontal scale is arranged on the vertical plate surface of the transparent box body.

[0008] A top cover is arranged on the top of the transparent box body.

[0009] The transparent box body is annular and its outer diameter is the same as the inner diameter of the caisson.

[0010] A plurality of fixing devices are arranged at intervals along the circumferential direction of the transparent box body, and the fixing devices include a vertical steel plate for connecting the transparent box body and a horizontal steel plate for connecting the top surface of the caisson, the horizontal steel plate is connected to the top of the vertical steel plate, and the end of the horizontal steel plate pointing to the outside of the caisson has a downwardly bent limit plate so that the horizontal steel plate can be buckled on the top surface of the caisson.

[0011] The utility model has the advantages that the transparent box body is arranged in a ring shape and is buckled on the top of the caisson, so that the overall inclination of the caisson can be measured, thereby overcoming the shortcoming that the traditional inclinometer can only measure the local inclination.

[0015] The features of the present invention and other related features are further described in detail below through embodiments in conjunction with the accompanying drawings to facilitate understanding by technicians in the same industry:

[0016] like Figure 1-3 , the marks in the figure are: caisson 1, transparent box 2, fixing device 3, vertical steel plate 31, horizontal steel plate 32, limit plate 33, horizontal scale 4, liquid level 5.

[0017] Example: Figure 1 , 2 As shown in FIG. 3 , this embodiment specifically relates to a monitoring device for measuring the overall inclination of a caisson. The main body of the monitoring device is a transparent box body 2 , which is fixedly arranged at the top end of a caisson 1 via a fixing device 3 .

[0018] like Figure 1-3 As shown, the transparent box body 2 is made of acrylic material, and the transparent box body 2 is annular as a whole, and its outer diameter matches the inner diameter of the caisson 1, and can be just assembled on the top of the caisson 1 and detachably fixed through the fixing device 3. The transparent box body 2 is filled with water, and a horizontal scale 4 is engraved on the vertical plate surface of the transparent box body 2, as shown in FIG. Figure 3 shown.

[0019] like Figure 1-3 As shown, the fixing device 3 is arranged at intervals along the annular direction of the transparent box body 2, and the fixing device 3 includes a vertical steel plate 31 for connecting and fixing the transparent box body 2 and a horizontal steel plate 32 for connecting the top surface of the caisson 1. The end of the horizontal steel plate 32 pointing to the outside of the caisson 1 has a downwardly bent limit plate 33, so that the transparent box body 2 can be directly buckled on the top of the caisson 1 through the fixing device 3 during installation, which is convenient for subsequent disassembly and movement. It should be noted that the vertical steel plate 31, the horizontal steel plate 32 and the limit plate 33 adopt an integrated bending molding process.

[0020] like Figure 1-3As shown, during the sinking process of the caisson 1, if the liquid surface 5 remains horizontal, it means that the caisson 1 has not tilted. When an angle is formed between the liquid surface 5 and the horizontal scale 4, it means that the caisson 1 has tilted during the sinking process. The inclination of the caisson 1 is calculated by the angle between the liquid surface 5 and the horizontal scale 4, and the maximum value of the change between the liquid surface 5 and the horizontal scale 5 is the horizontal inclination direction of the caisson 1.

[0021] The utility model has the advantages that the transparent box body is arranged in a ring shape and is buckled on the top of the caisson, so that the overall inclination of the caisson can be measured, thereby overcoming the shortcoming that the traditional inclinometer can only measure the local inclination.
