The invention provides a deeply-buried rain water pipe deformation monitoring device and method, and relates to the technical field of underground pipe deformation monitoring. The method is used for solving the problem that deformation of a deeply-buried rain water pipe cannot be measured accurately in real time through a method that the deformation of the deeply-buried rain water pipe is manually and indirectly monitored. The deeply-buried rain water pipe deformation monitoring device comprises a first fixing portion, an adjustable portion and a second fixing portion. The first fixing portion is provided with a horizontal displacement sensor, and the second fixing portion is provided with a vertical displacement sensor. The upper end of the first fixing portion is connected with the upper surface of the inner wall of the deeply-buried rain water pipe in a tightly supported mode, and the lower end of the first fixing portion is connected with the upper end of the adjustable portion in a clamped mode. The lower end of the adjustable portion is movably connected with the upper end of the second fixing portion in an up-down telescopic mode. The lower end of the second fixing portion is connected with the lower surface of the inner wall of the rain water pipe in a tightly supported mode. By means of the device, deformation of the rain water pipe can be measured accurately in real time. The monitoring method includes the steps that (1) the monitoring device is installed, and the horizontal displacement sensor and the vertical displacement sensor are debugged; (2) monitoring data are collected through a data collection and monitoring system; (3) the data are analyzed and processed through a data center server.
Description
technical field [0001] The invention relates to the technical field of underground pipeline deformation monitoring, in particular to a deep-buried rainwater pipe deformation monitoring device and monitoring method. Background technique [0002] With the development of urban underground space becoming increasingly three-dimensional and networked, more and more new underground projects will pass through existing underground facilities. In addition to dealing with the safety risks of conventional underground engineering construction, the crossing construction of underground projects also needs to face the safety management and control risks of existing facilities at crossing nodes. Ineffective control over the security status of existing facilities is likely to lead to huge losses or catastrophic accidents. Especially for large-scale underground rainwater pipe networks, which are usually buried deep underground, and generally large-scale rainwater main lines are mostly distrib...
