Embodiment Construction

[0013] The device includes a reference static level, a measurement static level, and a data processing module. The reference static level and the measurement static level are connected to the data processing module respectively; The level is arranged on the top of the space structure, and the reference static level and the measurement static level are connected through pipelines.

[0014] The reference static level is communicated with the measuring static level through water or oil provided in the pipeline. All measuring static levels are set at the same height. The data processing module is a PC.

[0015] The measurement method using the above equipment is:

[0016] 1. Select test points and reference points according to the test requirements.

[0017] 2. Lay out the pipeline along each test point.

[0018] 3. Fix each static level to the corresponding test point and reference point, and adjust the relative height of each measurement static level (preferably on the same ...

Abstract

The invention relates to a measuring device, in particular to an accurate measuring device for the vertical deformation of a space structure. The space structure vertical deformation measuring device of the present invention comprises a reference static level, a measurement static level, and a data processing module, and the reference static level and the measurement static level are respectively connected to the data processing module; the reference static level is arranged in the space structure On the fixed datum point of , the measurement static level is arranged on the top of the space structure, and the reference static level and the measurement static level are connected through pipelines. The device measures the vertical deformation of the space structure, has high measurement accuracy, long-term stable and reliable performance, a large measurement range and high sensitivity.

Description

technical field [0001] The invention relates to a measuring device, in particular to an accurate measuring device for the vertical deformation of a space structure. Background technique [0002] Foundation settlement refers to the subsidence of the foundation surface caused by the compaction of the foundation soil layer under the action of additional stress. Excessive settlement, especially uneven settlement, will cause the building to tilt and crack so that it cannot be used normally. [0003] Before buildings and geotechnical structures are built, the self-weight stress of the soil's own gravity already exists in the foundation. The load of buildings and geotechnical structures is transmitted to the foundation through the bottom surface of the foundation or embankment, which changes the original stress state of the natural soil layer. Under the action of the additional three-dimensional stress component, the foundation produces vertical, lateral and shear forces. Shear d...
