Description
Technical Field
The utility model belongs to the field of automatic tunnel overexcitation and underexcavation detection, and provides an underexcavation detection device.
Background
The undermining detection is a sub-item which is necessary to be detected in tunnel engineering and is used for evaluating the undermining degree after tunnel blasting. The over-and-under-excavation detection can detect the over-and-under-excavation position and the over-and-under-excavation degree of the tunnel in construction, so that the damage of the over-and-under-excavation to the safety of the tunnel can be timely obtained.
With the continuous advancement of national infrastructure construction, a large number of highway constructions are developed across the country. Expressways are built in mountain areas, and tunneling of tunnels is inevitably required. The problem of the super-undermining phenomenon of the highway tunnel in blasting construction is very common. The tunnel overexcavation refers to that a part of a section actually excavated outside a reference line is called overexcavation, and a part inside the reference line is called underexcavation, with reference to a tunnel design excavation contour line. Therefore, it is necessary to provide a device that can perform the underrun detection in the whole process, and unnecessary potential safety hazards can be eliminated to a great extent.
At present, the commonly adopted super-underexcavation detection device in the highway tunnel is a monitoring instrument such as a total station, a water-level detector and a laser range finder, and the detection mode is that after tunnel blasting, the monitoring point is manually arranged in the tunnel, and the point location coordinates are measured through a traditional instrument such as the total station, the water-level detector and the laser range finder. However, under the complex tunnel environment, the data measured by the total station and the level are too huge, and the time spent for collecting the coordinates of each section is more, so that the observation precision is reduced; the patent 2021105048030 discloses a device and a method for detecting tunnel overexcitation, which adopts a laser range finder for measurement, and the laser range finder can not measure obstacles, which is a fatal defect of the laser range finder. Meanwhile, constructors do not know the condition of the tunnel excavation section, measurement data can stay in the tunnel for a large amount of time, the tunnel can be flattened and slumped at any time, and potential safety hazards can be caused.
Therefore, a new detecting device is needed to detect the tunnel in real time, so as to avoid surrounding rock collapse and engineering accidents.
