Embodiment 1

[0025] Embodiment 1: A MEMS array-based continuous observation device for dam deformation during construction, see Image 6 with Figure 8 , the embedded MEMS sensors 12 are distributed in the strip (or columnar) carrier 11, and each MEMS sensor 12 is connected to the processor 15 through the data line 13, and the processor 15 transmits to the monitoring system through wired or wireless means. The belt-shaped (or columnar) carrier 11 is made of flexible anti-corrosion and tensile materials. According to the position changes of the sensors at different positions and the angle changes between adjacent position sensors, it is converted into a visible state or a monitorable state, so as to determine the degree of deformation of the dam body 2 .

Embodiment 2

[0026] Example 2: see Figure 7 , is a further supplement to Embodiment 1. If the length of the strip (or columnar) carrier 11 is insufficient, adjacent strip (or columnar) carriers 11 can be connected through the data line plug 16 and the data line slot 17 fixed.

[0027] Embodiment 3: The first MEMS array-based method for continuous observation of dam deformation during construction is a foundation monitoring method. A MEMS array-based continuous observation device for dam deformation during construction is buried at a certain depth of the foundation by drilling holes, and a certain point in the foundation is set as a reference point to start the layout for observing the deformation of the foundation. Among them, the MEMS array-based continuous observation device for dam deformation during the construction period is distributed with embedded MEMS sensors 12 in the strip (or columnar) carrier 11, and each MEMS sensor 12 is connected to the processor 15 through the data line 13, and the processor 15 passes Wired or wireless transmission to the monitoring system.

Abstract

The invention discloses a continuous observation method and a continuous observation device for dam deformation based on an MEMS array. The continuous observation device for dam deformation based on the MEMS array is embedded at a certain depth of a foundation in a punching manner. Furthermore a certain point in the foundation is used as a reference point for starting arrangement, thereby observing deformation of the dam. The observation device is provided with embedded MEMS sensors which are distributed in a band-shaped carrier. Each MEMS sensor is connected with a processor through a data line. The processor transmits a signal to a monitoring system in a wired or wireless manner. The continuous observation method and the continuous observation device perform the following functions in the construction period of a high concrete dam and a period after completing, monitoring the deformation state of the dam body in real time, monitoring the change state between the dam body and the foundation in real time, and quickly and comprehensively reflecting all changes. Therefore an effective observation means for dam body deformation of the high concrete dam is added. The continuous observation method and the continuous observation device have advantages of simple method, easy application, high monitoring precision, comprehensive monitoring, high real-time performance and high effect. Furthermore manpower, physical resource and cost are saved.

Description

technical field [0001] The invention belongs to the technical field of deformation monitoring during construction of high dams, and in particular relates to a method and device for continuously observing deformation during construction of a dam based on a MEMS array. Background technique [0002] High concrete dams are generally divided into joints and blocks, and the size of the columnar pouring blocks depends on the width of the dam block and the distance between the joints along the river. During the pouring process of the dam, as the dam block rises, the self-weight load continues to increase, and both the dam block itself and the foundation deform. When the allowable value is exceeded, it will affect the safety of the dam during the construction period and the safety of the later operation. Therefore, the code stipulates the height difference and cantilever height of the corresponding dam blocks of the concrete dam, but the actual construction often exceeds the specifi...
