Embodiment Construction

[0015] The specific implementation manners of the present invention will be discussed in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 , figure 2 with image 3 As shown, a static level monitoring system in this embodiment includes a data acquisition system 1, a cable 6, a reference water tank 3, a static level 2, a connecting pipe 5 and a free water level end 4; the data acquisition system 1 adopts a GT-204 vibrator String reading instrument, or other vibrating wire frequency reading devices such as XTX-04 vibrating wire sensor measurement unit or other vibrating wire automatic measurement modules can be used to obtain monitoring data. The cable 6 uses an ordinary signal cable, and the data acquisition system 1 passes through the 6 is connected to the signal end of the static level 2, the reference water tank 3 adopts a stainless steel container that can store liquid, and the connecting pipe 5 adopts a nylon connecting pipe, or a conn...

Abstract

The invention provides a static level monitoring system, comprising a data acquisition system, a reference water tank, a static level gauge and a communicating pipe; at least one static level gauge is respectively connected with the reference water tank through the communicating pipe; and the data acquisition system is connected with the signal end of the static level gauge. The invention has the following advantages: the sedimentation or flotation of structures such as foundation fill is measured in time; the measuring range is large, the sensitivity is high, and the measuring efficiency is high; and the system is applied to round-the-clock remote monitoring and automatic data acquisition.

Description

technical field [0001] The invention relates to a precision measurement system for settlement or buoyancy of foundation filling structures in civil engineering, in particular to a static level monitoring system. Background technique [0002] With the development of society and economy, infrastructure construction is in the ascendant, and a large number of hydropower dams, high-rise buildings, highways, bridges, embankments, oil and gas pipelines, and oil storage tanks have been built in large quantities, and it is necessary to carry out settlement or buoyancy of the foundation filling structure. Take a lot of precision measurements. At present, the measurement of subsidence or buoyancy is mainly carried out manually through precise level gauges, resulting in large measurement errors, low efficiency, and high labor intensity. Measurements cannot be carried out around the clock. There is no real-time risk assessment and monitoring system, and engineering buildings cannot be fo...
