Description

Technical Field

[0001] The present invention relates to the technical field of hoisting engineering monitoring, and in particular to a large-scale hoisting machinery station foundation settlement monitoring system. Background Art

[0002] When large equipment lifting machinery is used for lifting operations on soft foundations, especially in coastal areas, it is necessary to strictly control the settlement of the soft foundation at the machinery station. Before the lifting operation, the foundation of the station area is usually treated with silt solidification or replacement methods to improve the bearing capacity of the foundation and reduce the foundation settlement caused by the lifting machinery transferring a large load to the foundation under its station. In particular, differential settlement will directly affect the safety of the lifting operation. Therefore, it is necessary to monitor the foundation settlement during the lifting operation to ensure the safety of the project. At present, the settlement observation during the lifting operation is mainly carried out manually using a level. This method takes a long time to measure multiple points at a time, and the amount of data calculation is large. It is impossible to grasp the foundation settlement during the lifting operation in a timely manner, which affects the judgment of the lifting safety. Therefore, there is an urgent need for a monitoring system that does not require manual measurement and internal calculations, can realize the automatic collection of multi-point foundation settlement, and can calculate the differential settlement of related points, and intuitively reflect the real-time situation of the foundation of the lifting station. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art and to provide a monitoring system that does not require manual measurement and internal calculations, can automatically collect the settlement of multiple points of the foundation, and can calculate the differential settlement of related points, intuitively reflecting the real-time situation of the foundation at the lifting station.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] A large-scale lifting machinery station foundation settlement monitoring system includes a static level, a liquid storage tank, and a data acquisition instrument. The static levels are continuously arranged at the same height in a foundation treatment area. Adjacent static levels are connected in sequence through liquid hoses and gas hoses. Each static level matches the position of a roadbed box above the foundation treatment area and corresponds to the middle of the roadbed box. A foundation pier is provided outside the foundation treatment area; a static level is separately provided on the foundation pier, and the static level is connected to the liquid hose and gas hose extending from the foundation treatment area, wherein the liquid hose is connected to the liquid storage tank on the foundation pier, and the end of the gas hose is connected to the external atmosphere; after antifreeze is poured into the liquid storage tank and the liquid hoses of each static level are filled, the liquid level in the liquid storage tank is kept stable.

[0006] Furthermore, a pressure-bearing protective cover is provided on the outside of the static level, a pressure-bearing protective tube is connected between the pressure-bearing protective covers, and cables, liquid hoses and gas hoses are all passed through the pressure-bearing protective tube.

[0007] Furthermore, cables are connected between adjacent static levels. The data acquisition instrument consists of an acquisition module, a communication module, and a power supply module. The acquisition module is connected to the static level through a cable to collect data, and the communication module exchanges information with the computer through a wired or wireless network.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] This invention combines a static level with a data acquisition device and a computer to achieve real-time monitoring of foundation settlement. The data acquisition device automatically collects and transmits data, avoiding the loss and delays caused by offline recording and transmission. The computer receives, calculates, and stores the data, reducing surveyors' workload and ensuring data reliability and long-term storage. It also calculates differential settlement at associated points and issues alerts for points exceeding preset thresholds, facilitating decision-making. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0016] like Figures 1 to 2As shown, a large-scale lifting machinery station foundation settlement monitoring system includes a static level 1, a liquid storage tank 2, and a data acquisition instrument 3. The static levels 1 are continuously arranged at the same height in the foundation treatment area 7, and adjacent static levels 1 are connected in sequence through liquid hoses 9 and air hoses 10. Each static level 1 matches the position of the roadbed box 6 on the upper part of the foundation treatment area 7 and corresponds to the middle part of the roadbed box 6. A foundation pier 5 is provided outside the foundation treatment area 7; a static level 1 is separately provided on the foundation pier 5, and the static level 1 is connected to the liquid hose 9 and the air hose 10 extending from the foundation treatment area 7, wherein the liquid hose 9 is connected to the liquid storage tank 2 on the foundation pier 5, and the end of the air hose 10 is connected to the external atmosphere; after antifreeze is poured into the liquid storage tank 2 and the liquid hoses 9 of each static level 1 are filled, the liquid level of the liquid storage tank 2 is kept stable.

[0017] The static level 1 is provided with a pressure-bearing protective cover on its exterior, connected to a pressure-bearing protective tube. The cable 8, liquid hose 9, and gas hose 10 are all threaded through the pressure-bearing protective tube. The pressure-bearing protective cover and the pressure-bearing protective tube protect the static level 1, cable 8, liquid hose 9, and gas hose 10. The pressure-bearing protective tubes are connected by flexible connectors to ensure coordination with soil settlement and deformation.

[0018] A cable 8 connects adjacent static levels 1. The data acquisition device 3 comprises an acquisition module, a communication module, and a power supply module. The acquisition module is connected to the static levels 1 via cable 8 to collect data, and the communication module interacts with a computer 4 via a wired or wireless network. Automatic data collection and transmission by the data acquisition device avoids loss and delays caused by offline recording and transmission. Data is received, calculated, and stored by a computer, saving surveyors' workload and ensuring data reliability and long-term storage. In this embodiment, the data acquisition device 3 utilizes an RS485 data acquisition device.

[0019] like Figure 3As shown, the static levels 1 arranged continuously within the foundation treatment area 7 serve as settlement measurement points, used to measure the settlement of each roadbed box 7. The static levels 1 individually positioned on the foundation piers 5 serve as settlement references, used for comparison after differential settlement occurs among the static levels 1 within the foundation treatment area 7. After the static levels 1 within the foundation treatment area 7 are connected sequentially, the static level 1 closest to the foundation pier 5 is connected to the static level 1 serving as the settlement reference via a cable 8, a liquid hose 9, and an air hose 10. Antifreeze is then poured into the liquid reservoir 2, filling the liquid hoses 9 of each static level 1 to maintain a stable liquid level. The air hose 10 is connected to atmospheric pressure and works in conjunction with the static level 1. The liquid storage tank 2 and the static level 1 are connected by a liquid hose 9 to realize the principle of a communicating vessel. The liquid hose 9 is filled with antifreeze liquid, and the liquid storage tank 2 is stationary, which is equivalent to a constant water surface. When the static level 1 sinks, the water pressure felt is greater, and the amount of settlement can be calculated based on the pressure.

[0020] The computer 5 is a system and hardware used to receive data from the data acquisition device 3 and to calculate, store and display the data. ij It can be calculated by the following formula: ΔH ij =(H 00 -H i0 )-(H 0j -H ij ); where H 00 is the first stable measurement value of the settlement benchmark, H i0 is the first stable measurement value of the settlement measuring point i at the same time as the settlement reference point, H 0j is the measured value of the jth settlement benchmark, H ij is the j-th settlement measurement value of settlement measuring point i (i, j ≥ 1).

[0021] Differential sedimentation s can be calculated by the following formula: s = |ΔH aj -ΔH bj | / l ab ; where ΔH aj is the settlement value measured at settlement measuring point a for the jth time, ΔH bj is the settlement value of settlement measuring point b at the jth measurement, l ab The distance between settlement measuring point a and settlement measuring point b. The computer 5 can also monitor the settlement value ΔH of each point in the data. ij Or the differential sedimentation s is compared with a preset threshold and an alarm signal is issued if it exceeds the limit.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
