Highway tunnel geological detection system with self-adaptive fitting device and method

Abstract

The invention discloses a highway tunnel geological detection system with a self-adaptive fitting device and method. Through cooperation of a lifting trolley and a rotating motor, a radar antenna in an antenna clamping box can stably move forwards along the uneven tunnel surface, and through the telescopic characteristic of a first spring in the antenna clamping box, the radar antenna does not change along with the uneven tunnel surface or the change of the distance between the advancing trolley and the tunnel surface. Thus, the problem that the tunnel surface height measured by manpower is too large and touch is difficult is solved; continuous work can be achieved, and the cruising ability is high; workers do not need to work high above the ground, and safety of the workers is guaranteed.The scheme is reasonable, the structure is simple, used equipment is conventional, and good economic benefits and social benefits are achieved.

Description

technical field [0001] The invention belongs to the field of tunnel construction, and in particular relates to a highway tunnel geological detection system and method with an adaptive bonding device. Background technique [0002] Tunnel construction is a concealed project, and the unpredictability in design and construction is greater than other projects. Ground radar is an electromagnetic wave method used to determine the distribution of underground media. The principle of the method is similar to reflection seismic exploration technology, and it is a high-resolution detection method. At present, this technology is widely used in the grouting situation behind the wall of various tunnels and the test detection of determining the number of steel arch frames. The gap between the grouting body (that is, the thickness and defects of the grouting body), so as to quickly grasp the filling situation and construction quality of the grouting fluid between the segment and the soil, a...

AI Technical Summary

Problems solved by technology

[0006] ①According to the working principle of the radar, the antenna needs to be closely attached to the surface of the tunnel, but the highway tunnel has a long mileage, and it is easy to fatigue when lifting the antenna by manpower

②The design elevation of highway tunnels is generally about ten meters, and it is unsafe for personnel to work at heights for a long time

③When working for a long time, the human measurement will occasionally cause the separation between the antenna and the surface of the segment, which makes the data collection interrupted or suspended, which seriously affects the data quality of the grouting quality inspection after the segment wall

④ During the construction of highway tunnels, there will be steel skeletons on the surface, and it is easy to scratch the steel skeletons during human measurement, causing casualties

[0007] Method (II) has the following disadvantages: due to the unevenness of the tunnel surface, the traditional bracket supporting the radar antenna on the measurement vehicle does not use an adaptive fitting device, so it is very easy to get stuck at the raised position on the tunnel surface

The above-mentioned device has certain practicability in terms of adaptive fit, but it does not solve the problems of manual lifting of the radar antenna, the danger of working at heights, and the fatigue of human labor for a long time.

In addition, compared with shield tunnels, road tunnels have rough and uneven surfaces, and the above devices are not suitable for road tunnels.
