Description

Technical Field

[0001] This utility model relates to the field of spatial deformation measurement of caisson foundation technology, specifically to a combined device for measuring the vertical and horizontal displacement of caisson foundations. Background Technology

[0002] Caisson foundations, used along coastlines and revetments, are a crucial foundational structure for offshore engineering. They provide support through their large weight and extensive contact area, bearing the weight of structures or equipment above them. They offer stable foundations for buildings, docks, bridges, offshore wind turbines, and more, ensuring their safe placement in the marine environment.

[0003] The settlement and horizontal displacement of the caisson foundation directly affect the stability of the overall structure. Therefore, the settlement and horizontal displacement values ​​of the caisson foundation can be used to assess the stability of the foundation, thereby guiding the construction of the superstructure. Construction of the superstructure should only proceed after the caisson foundation has stabilized, and the displacement changes of the caisson foundation during the entire superstructure construction process can be monitored to ensure the safety of the project.

[0004] The level of automation in the field of civil engineering is extremely low. In conventional projects, manual monitoring is commonly used, with monitors employing total stations and levels to observe settlement. This method introduces a significant portion of errors due to human factors, is not only time-consuming and labor-intensive, but also unsuitable for underwater caisson foundations such as those on the coast or revetments. In the emerging field of automated monitoring, hydrostatic levels are used for settlement monitoring. Hydrostatic levels operate on the principle of "connecting pipes," but they are relatively large and difficult to install on structural components such as rails and turnouts. They are easily affected by the superstructure, and underwater operation can lead to water ingress and damage to the connecting pipes, causing the equipment to malfunction.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] refer to Figures 1 to 6As shown, the first embodiment of this utility model discloses a combined device for measuring the vertical and horizontal displacement of a caisson foundation, which includes: a cloud platform, a magnetostrictive displacement meter assembly, and a wireless composite sensor assembly. The permanent building structure and multiple caisson foundations are connected by the magnetostrictive displacement meter assembly, and the wireless composite sensor assembly is configured on the caisson foundation.

[0028] The magnetostrictive displacement meter assembly is configured to collect the vertical relative displacement and the horizontal relative displacement of the caisson foundation.

[0029] The wireless composite sensor assembly is configured to collect angle information;

[0030] The cloud platform is configured to calculate the settlement and horizontal displacement values ​​of the caisson foundation based on the vertical relative displacement, horizontal relative displacement, and angle information.

[0031] Preferably, the angle information includes the angle data between the caisson foundation and the xy, xz, and yz planes.

[0032] Preferably, the magnetostrictive displacement meter assembly includes a first magnetostrictive displacement meter and a second magnetostrictive displacement meter, the same number as the number of caisson foundations. The first magnetostrictive displacement meter is disposed on the upper side of the first end face of the caisson foundation, and the second magnetostrictive displacement meter is disposed on the lower side of the first end face of the caisson foundation. The first magnetostrictive displacement meter is configured to collect the vertical relative displacement of the caisson foundation, and the second magnetostrictive displacement meter is configured to collect the horizontal relative displacement of the caisson foundation.

[0033] Preferably, the first magnetostrictive sensor and the second magnetostrictive sensor are configured to detect the relative deformation between two objects by means of the relative position change of the magnetic ring 1 and the top sensor 2.

[0034] Preferably, the first end face of the caisson foundation is the side facing away from the sea.

[0035] Preferably, the wireless composite sensor assembly includes the same number of wireless composite sensors as the caisson foundations, the wireless composite sensors being configured on the caisson foundations, and the wireless composite sensors being configured to detect the angular changes between the top surface of the caisson foundation and the established coordinate axes xy plane, xz plane, and yz plane.

[0036] Preferably, the caisson foundation is located on the opposite side from the sea.

[0037] Preferably, the permanent building structure is a building structure that is considered not to undergo relative deformation and horizontal deformation after experiencing a preset period of historical settlement.

[0038] Please see Figure 1In this embodiment, the foundation of caisson No. 1 is connected to the permanent building structure using a magnetostrictive displacement meter, and the foundations of the remaining caissons are also connected to each other using magnetostrictive displacement meters. Wireless composite sensors are deployed on each caisson foundation. The intelligent detection terminal acquires data from the magnetostrictive displacement meters and wireless composite sensors in real time and transmits the data to the platform.

[0039] Specifically, a spatial rectangular coordinate system is established with the midpoint of the side of the permanent building structure closest to the caisson foundation as the origin. The various structures are connected via magnetostrictive displacement gauges, allowing for the measurement of the relative displacement between connected points. The caisson foundation is equipped with wireless composite sensors, initially calibrated to 0°. Intelligent detection terminals monitor in real-time the angles between the caisson foundation and the xy, xz, and yz planes, as well as the magnetostrictive displacement gauge values, transmitting the data to the platform. This effectively solves the problem of not being able to monitor the spatial deformation of discontinuous caisson foundations in real-time in existing technologies, addressing the issue of unknowable spatial deformation of the caisson foundation during the entire construction process of the superstructure, thus ensuring the safety of construction and building.

[0040] The permanent building structure is considered to be one that will not undergo relative or horizontal deformation after a certain period of historical settlement. The magnetostrictive displacement gauge measures the relative deformation between two objects by the relative positional change of the magnetic ring 1 and the top sensor 2 (the magnetic ring 1 is relatively large in practical engineering applications, and lateral deformation will not be damaged). The caisson foundation is a reinforced concrete structure. The wireless composite sensor can measure the angular changes between the top surface of the caisson foundation and the established coordinate axes xy, xz, and yz planes. The magnetostrictive displacement gauge and the wireless composite sensor are positioned on the opposite side from the sea, and cannot be placed close to the center (as this would affect the sensor during the pouring of the superstructure).

[0041] In this embodiment, because the caisson foundation is a rigid body and its surface does not deform, with each surface remaining planar, the rotation of the entire caisson foundation in space can be obtained by observing its rotation. Adding this to the calculated settlement and horizontal displacement, the spatial changes of each caisson foundation can be determined. Based on data transmitted to the platform in real time, the spatial deformation of each caisson foundation can be calculated. Specifically, the settlement value H at the rightmost end of each caisson foundation is calculated. i And the rightmost horizontal displacement value L i The specific formula is: H i =H i-1 +g i +a i *sinα i and L i =L i-1 +k i +b i *(1-cosα i ), H iLet L be the rightmost settlement value corresponding to the i-th caisson foundation. i Let be the corresponding rightmost horizontal displacement value. Real-time monitoring is performed on the angles between the caisson foundation and the xy, xz, and yz planes, as well as the displacement values ​​of the magnetostrictive displacement gauges. Because the caisson foundation is a rigid body, its surface will not deform, and each surface remains planar. Therefore, by rotating the caisson foundation... The angles between the i-th caisson foundation and the xy, xz, and yz planes are denoted as α... i β i and γ i The length, width, and height of each caisson foundation are a, ... i b i and c i The vertical relative displacement obtained by the magnetostriction gauge connected to the left side of the caisson foundation is denoted as g. i The vertical relative displacement obtained by the magnetostrictive displacement meter connected to the right side of the caisson foundation is denoted as g. i+1 The horizontal relative displacement obtained by the magnetostrictive displacement meter connected to the left side of the caisson foundation is denoted as k. i The horizontal relative displacement obtained by the magnetostrictive displacement meter connected to the right side of the caisson foundation is denoted as k. i+1 1 ≤ i ≤ n, where n is the number of caisson foundations. The caisson foundation connected to the permanent building structure is designated as caisson foundation number one, the caisson foundation connected to caisson foundation number one is designated as caisson foundation number two, and so on.

[0042] It is important to note that the real-time spatial deformation of each caisson foundation can be obtained based on the transmitted data. The calculation results are not limited to the settlement and horizontal displacement values ​​at the rightmost end of each caisson foundation, as these two data points are representative. Therefore, the formula shown above is used to calculate and output these values ​​for each caisson foundation. Since settlement is the primary factor in the vertical direction of the caisson foundation, for ease of calculation, the vertically downward direction is taken as positive, and the angle is taken as positive in the counterclockwise direction. The method for calculating length in a spatial rectangular coordinate system is not unique; it can also be calculated using other side lengths and angles.

[0043] In summary, the combined device for measuring the vertical and horizontal displacement of the caisson foundation includes a magnetostrictive displacement meter, a wireless composite sensor, and a cloud platform. The No. 1 caisson foundation is connected to the permanent building structure using a magnetostrictive displacement meter, and the remaining caisson foundations are also connected using magnetostrictive displacement meters. Wireless composite sensors are deployed at each caisson foundation. Intelligent detection terminals acquire data from the magnetostrictive displacement meters and wireless composite sensors in real time. After the data is transmitted to the platform, calculations are performed to monitor the spatial changes of each caisson foundation in real time. This achieves real-time monitoring of the spatial deformation of discontinuous underwater caisson foundations, preventing the undetected abnormal spatial deformation of the caisson foundation and ensuring the safety of the entire superstructure construction process.

[0044] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
