Problems solved by technology
my country has carried out a lot of monitoring work on foundation pit slopes and road slopes. However, due to the complex geological conditions of the soil on the upside slope of the tunnel and the vegetation coverage, it is not easy to be found when the soil slips and cracks on the upside slope. At the same time, At home and abroad, there are still few instruments for tunnel elevation monitoring

The invention discloses a tunnel upward slope soil slippage and cracking monitoring instrument, which comprises a front point fixing device and a back point fixing device, wherein the front point fixing device comprises a fixing rod, and one end of the fixing rod is connected with a measuring instrument by a spherical valve; the back point fixing device comprises a fixing rod, wherein the middle part of the fixing rod is provided with a groove, a tape is arranged in the groove, one end, near the tape, of the fixing rod is connected with a spherical valve, and the top part of the spherical valve is provided with a positioning pin; the measuring instrument of the front point fixing device is connected with a tape body of the back point fixing device. The invention also discloses a method using the monitoring instrument to monitor the tunnel upward slope soil slippage and cracking. The monitoring instrument and the method have the advantages that the structure is simple and practical, the tunnel upward slope soil slippage and cracking of tunnel projects can be monitored, the deformation rule of the upward slope soil in the construction process can be timely controlled, and the safety construction of the actual tunnel project is favorably performed.
Description
technical field [0001] The invention relates to a method for monitoring the sliding and cracking of soil body on a tunnel upward slope, and belongs to the technical field of side / upward slope monitoring. Background technique [0002] Mountains are widely distributed in my country. To build underground tunnels in mountainous areas, it is necessary to observe the slipping and cracking of the upward slope in time to ensure the safety of the tunnel project and prevent disasters caused by the sliding and cracking of the upward slope. my country has carried out a lot of monitoring work on foundation pit slopes and road slopes. However, due to the complex geological conditions of the soil on the upside slope of the tunnel and the vegetation coverage, it is not easy to be found when the soil slips and cracks on the upside slope. At the same time, At home and abroad, there are still few instruments for tunnel elevation monitoring. Contents of the invention [0003] The object of th...
