Description

A large-scale hoisting machinery station foundation settlement monitoring system Technical Field

[0001] This utility model relates to the field of hoisting engineering monitoring technology, and in particular to a large hoisting machinery station foundation settlement monitoring system. Background Technology

[0002] When large equipment hoisting machinery operates on soft foundations, especially in coastal areas, it is crucial to strictly control the settlement of the soft foundation at the machinery's location. Before hoisting operations, the foundation in the area is typically treated with siltation or replacement methods to improve its bearing capacity and reduce foundation settlement caused by the large loads transferred by the hoisting machinery. Differential settlement, in particular, directly impacts the safety of hoisting operations; therefore, monitoring foundation settlement during hoisting operations is essential to ensure project safety. Currently, settlement observation during hoisting operations primarily relies on manual observation using a level instrument. This method involves time-consuming measurements at multiple points and requires extensive data processing, making it difficult to promptly grasp the foundation settlement situation during hoisting operations and affecting the assessment of hoisting safety. Therefore, there is an urgent need for a monitoring system that eliminates the need for manual measurement and data processing, automatically collects settlement data from multiple foundation points, calculates differential settlement at related points, and provides a direct reflection of the real-time condition of the foundation at the hoisting location. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and to provide a monitoring system that can automatically collect settlement data at multiple points of the foundation without manual measurement and office calculation, and can calculate the differential settlement of related points, thus intuitively reflecting the real-time situation of the foundation at the hoisting station.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A large-scale hoisting machinery foundation settlement monitoring system includes a static level, a liquid storage tank, a data acquisition instrument, and a computer. The static levels are continuously arranged at equal heights within the foundation treatment area. Adjacent static levels are connected sequentially by cables, liquid hoses, and air hoses. Each static level is positioned to correspond to the middle of a roadbed box above the foundation treatment area. Foundation piers are located outside the foundation treatment area. Each foundation pier has a separate static level connected to cables, liquid hoses, and air hoses extending from within the foundation treatment area. The cables are connected to the data acquisition instrument, the liquid hoses are connected to the liquid storage tank on the foundation pier, and the end of the air hose is open to the outside atmosphere. The liquid storage tank is filled with antifreeze, which fills the liquid hoses of each static level, maintaining a stable liquid level in the tank.

[0006] Furthermore, the static level is equipped with a pressure-bearing protective cover, and pressure-bearing protective pipes are connected between the pressure-bearing protective covers. Cables, liquid hoses, and gas hoses are all installed inside the pressure-bearing protective pipes.

[0007] Furthermore, the data acquisition instrument consists of an acquisition module, a communication module, and a power supply module. The acquisition module is connected to the hydrostatic level via a cable to acquire data, and the communication module interacts with the computer via a wired or wireless network.

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

[0009] This invention utilizes a hydrostatic level, a data acquisition instrument, and a computer to achieve real-time monitoring of foundation settlement. The data acquisition instrument automatically collects and transmits data, avoiding data loss and delays caused by offline recording and transmission. The computer receives, calculates, and stores the data, reducing the workload for surveyors and ensuring data reliability and long-term storage. Simultaneously, it can calculate differential settlement at related points and issue alarms for points exceeding preset thresholds, facilitating decision-making by relevant personnel.

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

[0016] As shown in Figures 1 and 2, a large-scale hoisting machinery station foundation settlement monitoring system includes a hydrostatic level 1, a liquid storage tank 2, a data acquisition instrument 3, and a computer 4. The hydrostatic level 1 is continuously and uniformly arranged within the foundation treatment area 7. Adjacent hydrostatic level 1s are connected sequentially via cables 8, liquid hoses 9, and gas hoses 10. Each hydrostatic level 1 is positioned to correspond to the middle of the roadbed box 6 above the foundation treatment area 7. The foundation treatment area 7 is externally equipped with… A foundation pier 5 is provided; a static level 1 is separately installed on the foundation pier 5. The static level 1 is connected to a cable 8, a liquid hose 9, and a gas hose 10 extending from the foundation treatment area 7. The cable 8 is connected to a data acquisition instrument 3, the liquid hose 9 is connected to a storage tank 2 on the foundation pier 5, and the end of the gas hose 10 is open to the outside atmosphere. The storage tank 2 is filled with antifreeze and the liquid hoses 9 of each static level 1 are filled to maintain a stable liquid level.

[0017] The static level 1 is equipped with a pressure-bearing protective cover, and pressure-bearing protective pipes are connected between the pressure-bearing protective covers. The cable 8, liquid hose 9, and air hose 10 are all run through the pressure-bearing protective pipes. The pressure-bearing protective covers and pressure-bearing protective pipes are used to protect the static level 1, cable 8, liquid hose 9, and air hose 10. The pressure-bearing protective pipes are connected by flexible connectors to ensure coordination with soil settlement and deformation.

[0018] The data acquisition instrument 3 consists of a data acquisition module, a communication module, and a power supply module. The data acquisition module is connected to the hydrostatic level 1 via a cable 8 to acquire data, and the communication module interacts with the computer 4 via a wired or wireless network. The automatic data acquisition and transmission via the data acquisition instrument avoids data loss and delays caused by offline recording and transmission. The computer receives, calculates, and stores the data, saving surveyors' workload and ensuring data reliability and long-term storage. In this embodiment, the data acquisition instrument 3 is an RS485 data acquisition instrument.

[0019] As shown in Figure 3, the static level instruments 1 arranged continuously within the foundation treatment area 7 serve as settlement measuring points to measure the settlement of each roadbed box 7. A separate static level instrument 1 arranged on the foundation pier 5 serves as a settlement benchmark, used for comparison after differential settlement is observed in the static level instruments 1 within the foundation treatment area 7. The static level instruments 1 within the foundation treatment area 7 are connected sequentially. The static level instrument 1 closest to the foundation pier 5 is connected to the static level instrument 1 serving as the settlement benchmark via cable 8, liquid hose 9, and air hose 10. Antifreeze is filled into the storage tank 2 and the liquid hoses 9 of each static level instrument 1 are filled to maintain a stable liquid level in the storage tank 2. The air hose 10 is connected to atmospheric pressure and works in conjunction with the static level instrument 1. The liquid storage tank 2 and the hydrostatic level 1 are connected by a liquid hose 9 to realize the principle of communicating vessels. The liquid hose 9 is filled with antifreeze, and the liquid storage tank 2 is stationary, which is equivalent to a fixed water level. When the hydrostatic level 1 settles, the water pressure it feels is greater, and the amount of settlement can be calculated based on the pressure.

[0020] Computer 5 is the system and hardware used to receive data from data acquisition instrument 3, and to perform calculations, store, and display the data. During the j-th measurement, the settlement value ΔH of settlement measurement point i relative to the settlement reference is... ij It can be calculated by the following formula: ΔH ij =(H 00 -H i0 )-(H 0j -H ij ); where H 00 H is the initial stable measurement value of the settlement benchmark point. i0 H represents the first stable measurement value at settlement measuring point i, taken simultaneously with the settlement reference point. 0j H is the measured value of the j-th settlement benchmark. ij Let be the settlement measurement value of settlement point i at the j-th time (i,j≥1).

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