Embodiment 1

[0021] Various standards related to the settlement of the storage tank foundation have different requirements for the settlement. However, the specific requirements are the settlement difference between adjacent points (not greater than 10m) and between two points in the diameter direction upward of the foundation ring. Therefore, it is necessary to measure the coordinates of the tank foundation in the same coordinate system, so as to evaluate whether the foundation meets the requirements.

[0022] device installation

[0023] For specific measurements, such as figure 1 and figure 2 As shown, the tripod is placed in the upper left corner of the fire embankment, and the distance from the north and west wall dikes is about 2m. After the tripod stand is placed, fix the total station on the stand and level it. The recorder is connected to the total station via Bluetooth.

Abstract

The invention relates to a method for external measurement of settlement of the foundation of a storage tank. The method for external measurement of settlement of the foundation of the storage tank mainly solves the problem that in the prior art, measurement of all coordinate points in the circumferential direction of the storage tank can not be achieved at one position. According to the method for external measurement of settlement of the foundation of the storage tank, the height of the coordinate of a foundation point of the storage tank is measured by means of a total station, communication between a data recorder and the total station is established, data obtained through measurement of the total station are stored automatically, a prism is adopted to serve as a measurement point for the height of the foundation of the storage tank and is placed on the foundation of the storage tank, and the prism is moved to the next position each time a settlement point is measured; after settlement measurement of one station measurement point is completed, measurement is conducted on another station, at least three groups of switching points are arranged, coordinate points of different measured stations are converted into the same coordinate system through coordinate transformation, and then measurement of the coordinates of the settlement points is well completed. The method is used for external measurement of settlement of the foundation of the storage tank.

Description

technical field [0001] The invention relates to an external measurement method for the foundation settlement of a storage tank. Background technique [0002] The settlement of the storage tank foundation refers to the subsidence of the foundation surface caused by the compaction of the foundation of the storage tank under the stress of the storage tank itself, the oil in the tank and the external load (wind, rain, etc.). Excessive settlement, especially uneven settlement, will cause the storage tank to tilt and deform, resulting in the increase of the liquid level of the storage tank and the occurrence of accidents such as floating disc chucking. [0003] The tank foundation settlement measurement assessment is to calculate the height difference between the foundation measurement points along the circumference of the tank. Therefore, it is necessary to measure the height of the tank foundation in the same coordinate system. [0004] CN201110029507.6 relates to a large-scal...
