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

Embodiment Construction
[0023] Below in conjunction with accompanying drawing and embodiment this patent is further described.
[0024] Figure 1~3 Among them, a monitoring instrument for monitoring the sliding and cracking of tunnel upside slopes, which consists of two parts: the front point fixing device and the rear point fixing device;
[0025] The front point fixing device includes: a second metal rod 7 connected and fixed in sequence, a second rotatable ball valve 8, and an electronic intelligent measuring instrument 9, and the second metal rod 7 is buried in the soil for fixing the front point Fixing device; the second rotatable spherical valve 8 can be rotated 360 degrees along the second metal rod 7, which can ensure the use of two points at different slopes; the electronic intelligent measuring instrument 9 includes a micro-display and a terminal The end ring 10 is used to display the displacement change between two points after the end ring 10 is pulled to generate displacement. By record...

The invention relates to a monitoring instrument for monitoring slippage and cracking on the heading slope soil body of a tunnel. The monitoring instrument comprises a front monitoring point fixing device and a rear monitoring point fixing device, wherein the front monitoring point fixing device comprises a metal hard rod embedded into the soil body, a spherical valve and an electronic intelligence measuring instrument; the rear monitoring point fixing device comprises a metal hard rod embedded into the soil body, a steel tape, a spherical valve and a locating pin. Moreover, the invention further discloses a monitoring method for the monitoring instrument. The monitoring method for monitoring slippage and cracking of an inverted arch during tunnel excavation, disclosed by the invention solves the problems that the slippage and cracking of the inverted arch of the tunnel cannot be accurately measured, and is closer to engineering practical application in comparison with the previous research, and the monitoring instrument can be used more widely.
Description
technical field [0001] This patent relates to the technical field of side / upside slope monitoring, in particular to a monitoring instrument for monitoring soil sliding and cracking on upside slopes of tunnels. 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, but due to the complex geological conditions of the soil and vegetation coverage on the upside slope of the tunnel, it is not easy to detect and warn when the soil slips and cracks on the upside slope; At the same time, there are still few instruments at home and abroad for monitoring the upside slope of tunnels. Contents of the invention [0003] Th...
