Method and device for directly measuring and monitoring the settlement and deformation of underground pipelines and building structures

Abstract

The invention discloses a method for directly measuring and monitoring sedimentation deformation of an underground pipeline and a building structure, and a measuring device of the method, and belongs to the technical field of underground engineering. The invention relates to the device for measuring deformation, which is arranged in the pipeline range affected by a construction area of other underground construction. A positioning steel wire for measuring sedimentation deformation is led as a standard line, and is fixed at a steel structure for fixing a steel wire in a vertical shaft. Measuring telescopic cylinders and measuring telescopic contact feet with same distance are fixed on the standard line, wherein the measuring telescopic cylinders are provided with tilt angle sensors and displacement sensors. A deformation curve of the underground pipeline is monitored through a relative displacement between the measured pipeline and a suspension line of the standard line. The method and the device are reliable and practical. The problem that sedimentation, caused by some construction of subways, tunnels, and underground construction structures, of an accessory area is hard to measure is solved. The real-time measured data can be sent to a construction manager through a 3G network, so that a major safety accident is prevented.

Description

technical field [0001] The invention relates to a test method and a test device for the settlement and lateral deformation of underground pipelines induced by tunnel construction such as subways and roads, and belongs to the technical field of underground engineering. Background technique [0002] The construction of urban infrastructure will inevitably encounter the problem of settlement and deformation caused by the mutual influence of underground structures. For example, subways and tunnels under roads are generally laid out along the direction of urban main roads in combination with the urban road network and passenger flow. Subway lines are generally underground lines, and underground pipelines are densely distributed. Therefore, when constructing underground tunnels in cities such as subways and roads, they will face the problem of settlement and deformation caused by construction of adjacent existing underground pipelines. [0003] The excavation disturbance of tunnel...

Problems solved by technology

[0007] In order to solve the problem of directly measuring the settlement and lateral deformation of underground pipelines, the present invention proposes a method and device for directly measuring pipeline settlement and lateral deformation in underground pipelines, including: the underground pipeline (1) has little influence Take the reference point of geodetic coordinates (geodetic network) outside the range of the underground pipeline (1) and introduce it to the fixed steel wire structure (21) in the shaft (2) inside the underground pipeline (1) as the benchmark point for pipeline deformation testing. The device (4) accurately measures the vertical and lateral deformation of the underground pipeline (1) and perpendicular to the pipeline (1), and then uses the public 3G communication network to send the measurement data to relevant construction management personnel in real time;
