Problems solved by technology

Once these accidents happen, it will affect the construction period at least, increase the project investment, and destroy the machinery and equipment, and even cause casualties. Moreover, the handling work after the accident is difficult
At present, the existing technology is still unable to solve the problem of high-resolution detection and accurate prediction of the spatial position of abnormal geological conditions in the deep underground and deep in the tunnel face

Embodiment Construction

[0008] The structural principle and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0009] Referring to the accompanying drawings, a geological information collection device based on tunnel construction includes a radar antenna 1 arranged in the tunnel. The radar antenna 1 is provided with an anti-collision shell 2. The radar antenna 1 is connected to a computer 4 through a wireless transmission device 3. .

[0010] The working principle of the present invention is:

[0011] When in use, tie the radar antenna with a soft rod and slowly put it into the detection hole, use the radar to collect signals, transmit the collected signals back to the computer through the wireless transmission device for processing, and then perform image interpretation; if there is no abnormal and bad geology, Proceed to the next step of construction.

Abstract

A geological information collecting device based on tunnel construction comprises a radar antenna which is arranged in a tunnel. An anti-collision shell is arranged outside the radar antenna. The radar antenna is connected with a computer through a wireless transmission device. The radar antenna is bound by a soft pole and slowly dropped into a detecting hole, a radar is used for collecting signals and sending the collected signals back to the computer through the wireless transmission device to be processed, and then image interpretation is performed. The geological information collecting device based on the tunnel construction has the advantages of being simple in structure, high in resolution ratio and high in accuracy.

Description

technical field [0001] The invention relates to a geological information collection device based on tunnel construction. Background technique [0002] In the construction of railways and highways, tunnels with a depth of more than hundreds of meters and a length of several kilometers or tens of kilometers are often encountered. Although the corresponding geological survey work has been done in the early survey and design process, it also has certain guiding significance for construction. However, due to the complexity of the rock mass, there may be large discrepancies between the data obtained from the survey and the actual situation revealed after the tunnel excavation. Tunnel construction has a lot of blindness, and accidents such as landslides, roof falls, and water gushes often occur unexpectedly during construction. Once these accidents happen, they will affect the construction period and increase the project investment, and even destroy the machinery and equipment, an...
