Embodiment approach １

[0059] Implementation mode 1: The device consists of a first liquid level sensor 1, a first floating ball 2, a first floating magnetic ring 3, an inert water 4, a pipeline 5, a first micro-deformation sensor 6, a second liquid level sensor 7, and a second floating ball 8 , the second floating magnetic ring 9, the third liquid level sensor 10, the third floating ball 11, the third floating magnetic ring 12, the second micro-deformation sensor 13, the data collector 14, the connection line 15, the first cover 16, the second Two cover 17, the 3rd cover 18, the first bowl body 19, the second bowl body 20, the 3rd bowl body 21, computer 22 form, as figure 1 As shown, the monitoring device is composed of three monitoring bowls, the first bowl 19 is the reference monitoring point, the second bowl 20 and the third bowl 21 are used for the purpose of real-time deformation monitoring. Then the liquid level difference between the initial moment of the first bowl 19 and the i-th moment...

Embodiment approach 2

[0061] Implementation mode 2: In the case of Embodiment 1, the third bowl 21 is removed, and the device consists of the first bowl 19 and the second bowl 20 to form a connecting device. The first bowl 19 is the reference monitoring point, and the second bowl 20 is used for real-time deformation monitoring. , the same as in Embodiment 1, the calculation formula lacks the part where the fourth monitoring point 204 and the fifth monitoring point drop, that is

[0062] ?H 201i =(?H 202下 ) / 2

[0063] ?H 202i =(?H 202下 ) / 2

[0064] ?H 203下 =?H 203i +(?H 202下 ) / 2

[0065] In the same way, it can be concluded that ?H 202203 is ?H 202203 =?H 202下 -?H 203下 , according to ?H 202203 If the value is , the synchronization of the deformation of the monitoring point 202 and the monitoring point 203 can be obtained. The larger the difference, the worse the synchronization of the deformation.

Embodiment approach 3

[0066] Implementation mode 3: In the case of Embodiment 1, the fourth bowl 22 is added, and the device is composed of the first bowl 19, the second bowl 20, the third bowl 21 and the fourth bowl 22 to form a connecting device, and the first bowl 19 is used as the reference monitoring point, the second pot body 20, the third pot body 21 and the fourth pot body 22 are used as the purpose of real-time deformation monitoring, same as embodiment 1, here there are more sixth monitoring point 206, seventh monitoring point 207, then in the calculation formula The descending parts of the sixth monitoring point 206 and the seventh monitoring point 207 are added. Through the above three implementation methods, the formula can be summarized as follows:

[0067] Let 20S be the S monitoring point, and t be the total number of bowls (t≥2).

[0068] Then? H 201i =(?H 202下 +...+?H 20S下 ) / t {s=2n,n=1,2,...,2(t-1)}

[0069] ?H 20Si =[(t-1)?H 20S下 ] / t-(?H 202下+...+?H 20[2(t-1)]下 -?H 2...

Abstract

The invention discloses a device for measuring elevation position variation at different levels of monitoring points and an application method, which belong to the technical fields of construction of large bridges, high-rise buildings, high-speed railways, mines, large equipment, geological environmental monitor, geological disaster prewarning, and the like, as well as the deformation monitoring during the operation management. The device is characterized in that measurement bowls are placed at an elevation deformation monitoring station and connected with bowls installed at an elevation deformation stable point, so as to form a communicating vessel; and inertia water of appropriate amount is added, so as to timely and accurately measure the elevation position variation and the rate of the elevation position variation at different levels of the monitoring points. The variation of the elevation position at different levels of the monitoring points can be real-time and on-line mastered in a centralized manner through a computer, and construction of large bridges, high-rise buildings, high-speed railways, mines, large equipment, geological environment, geological disaster prewarning, and the like, as well as deformation operating condition during the operation management can be effectively monitored and controlled in a real-time and on-line manner. The device is simple, stable, reliable and not easy to damage.

Description

technical field [0001] The invention relates to a device and an application method for measuring elevation position changes at different levels of monitoring points, which belong to deformation monitoring in the construction and operation management process of large bridges, high-rise buildings, high-speed railways, mines, large equipment, geological environment monitoring, geological disaster early warning, etc. Technical field, specifically, a real-time online monitoring and monitoring device for timely and accurately measuring elevation position changes of monitoring points at different levels. Background technique [0002] In the process of construction and operation management of large bridges, high-rise buildings, high-speed railways, mines, large-scale equipment, geological environment monitoring, geological disaster early warning, etc., deformation monitoring often fails to take timely measures based on the deformation due to the inability to measure the deformation o...
