Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as figure 1 , 2 As shown, the method of using pressure difference to monitor the displacement of the anchor ingot structure adopts a pressure difference monitoring device in this method. The pressure difference monitoring device includes a reference point liquid pressure sensor 1, a measuring point liquid pressure sensor 2, a water tank 3 and water pipe 4.

[0026] The method for monitoring the displacement of an anchor ingot structure by using a pressure difference comprises the following steps:

[0027] 1) Fix the reference point liquid pressure sensor 1 in the anchor chamber, install the measuring point liquid pressure sensor 2 on the surface of the anchorage area 5, and install the water tank 3 at a certain distance above the reference point liquid pressure sensor 1.

[0028] 2) Fill the water tank 3 with water, an...

Abstract

The invention discloses a method for monitoring displacement of an anchor structure by utilizing a pressure difference. The method includes: step one, fixedly arranging a datum-point liquid-pressure sensor outside an anchor room, arranging a survey-point liquid-pressure sensor to a surface of an anchorage zone, and arranging a water tank above the datum-point liquid-pressure sensor; step two, filling monitoring ports of the datum-point liquid-pressure sensor and the survey-point liquid-pressure sensor with water through a valve and a water pipe, and removing the air; and step three, calculating the displacement of the anchorage zone in a forced direction according to changes of the pressure difference measured by the survey-point liquid-pressure sensor, and obtaining data such as wriggle frequency, range and long-term trend of the anchorage zone. According to the method, the pressure difference is used for monitoring displacement of the anchor structure so as to obtain relevant data such as the wriggle frequency, the range and the long-term trend of the anchorage zone, the monitoring accuracy and speed are high, a network can be accessed directly, requirements of internet of things are satisfied, and the detecting cost is low.

Description

technical field [0001] The invention relates to a method for monitoring the displacement of a suspension bridge, in particular to a method for monitoring the displacement of an anchor ingot structure by using pressure difference. Background technique [0002] Suspension bridge is one of the most commonly used extra-large and large-scale bridge types. These large-scale bridges are located in various traffic arteries, and the investment is huge, and the investment and maintenance costs are the highest among all bridge types. During the operation process, the traffic flow is very large and the load is heavy, which is of great significance to the construction of the national economy that cannot be underestimated. Once a safety accident occurs on these bridges, it will have serious consequences for the country's economic construction and social stability. Since the anchorage of the suspension bridge bears the horizontal force and vertical reaction force from the main cable, it i...
