Problems solved by technology

[0006] However, the subway tunnel is different from the surface engineering, and it is often difficult to meet the current observation work of the subway tunnel settlement by using the usual engineering measurement methods.
Compared with ground settlement observation, subway tunnel settlement observation usually faces the following problems: (1) Poor visibility conditions in the tunnel
(3) The observation in the cave can only be continued from one end to the other
(5) Each observation lasts for a long time
(6) Even the current automatic monitoring ("measuring robot" or static leveling observation) is to observe fixed observation points (with a distance of more than ten meters to tens of meters), which requires huge investment, and at the same time, continuous settlement observation along the line cannot be carried out
In view of the above characteristics, at present, the settlement observation of subway tunnels is mostly limited to the intervals where obvious settlement diseases have been found, and the settlement observation data does not have the characteristics of continuity of measurement points in the vertical direction (the distance between observation points is small), which is not conducive to a comprehensive understanding of settlement deformation and overall Grasp, it is easy to lead to the omission of dangerous situations

Abstract

The invention discloses a subway interval tunnel settlement observation method and device. The subway interval tunnel settlement observation method includes steps of inclinometry pipe arranging, horizontal inclinometer arranging, inclinometry data measuring and the like. The measuring device comprises an inclinometry pipe and a horizontal inclinometer, wherein a guide groove with a fixed direction is arranged in the inclinometry pipe, and a guide wheel is arranged on the horizontal inclinometer and clamped into the guide groove of the inclinometry pipe. The subway interval tunnel settlement observation method and device are continuous in measuring points, can perform measuring during subway operation and are short in measuring time and low in cost.

Description

Technical field [0001] The invention belongs to the field of observation of subsidence and deformation of underground engineering, in particular to a method and device for observation of subsidence of subway section tunnels. Background technique [0002] The subway project is an important infrastructure for improving transportation in large and medium-sized cities. my country's subway construction is 100 years later than the world, and cities such as Beijing, Tianjin, Shanghai, Guangzhou, Nanjing, and Shenzhen have already been put into operation. According to statistics, nearly 30 cities have been approved to construct subway projects in recent years. In the context of increasingly tight urban traffic, citizens have great expectations for the subway. I hope that the completion of the subway can bring convenience to transportation, and I also hope that the subway lines that have been in operation remain safe, comfortable and good. [0003] However, subway projects are mostly bui...
