Embodiment Construction
[0032] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0033] Due to the inaccurate measurement of the horizontal displacement and vertical displacement of the rockfill dam by using the tension line horizontal displacement meter and the water pipe settlement meter in the prior art, the present invention provides a monitoring pipeline for the internal deformation of the rockfill dam Layout method, specifically as figure 1 shown in . The internal deformation monitoring pipeline layout method of the rockfill dam specifically includes:

The invention discloses a method and system for laying monitoring pipelines for internal deformation of a rock fill dam. The method comprises steps that when the rock fill dam is constructed, a firstcurved flexible pipeline is buried at the to-be-monitored area inside the rock fill dam body, and the curved flexible pipeline deforms along with deformation of the dam body; operation analysis of therock fill dam body is performed, and the position where maximum horizontal displacement of the rock fill dam body occurs is determined; a second curved pipeline is disposed at the position where maximum horizontal displacement occurs, the second curved pipeline is spaced apart from the first curved pipeline by the predetermined distance, and the second curved pipeline has the same shape as the first curved pipeline. The method is advantaged in that compared with the traditional technology of monitoring the rock fill dam by using different sensors, a problem of sensor failure caused by protection pipeline damage of the sensor is effectively avoided, monitoring precision is improved, and horizontal displacement and vertical displacement of the rock fill dam can be simultaneously monitored,and cost is effectively saved.
Description
technical field [0001] The invention relates to the technical field of dam safety monitoring and measurement, in particular to a pipe laying method and system for monitoring internal deformation of a rockfill dam. Background technique [0002] The face rockfill dam is an important type of dam. The vertical settlement and horizontal displacement inside the dam body are important safety indicators to reflect the deformation status of the face rockfill dam. When these safety indicators exceed a certain threshold, the safety of the dam will be affected, so precise monitoring of these safety indicators is required. [0003] At present, the methods commonly used to monitor the internal deformation of rockfill dams include tension line horizontal displacement gauge and water pipe settlement instrument, among which tension line horizontal displacement gauge measures the horizontal displacement of rockfill dam, and water pipe settlement instrument measures the vertical displacement...
