Problems solved by technology

[0004] The inventor found in the research that the existing monitoring devices have a relatively single function, which can only monitor the water inrush point or harmful gas, and fail to combine the water inrush and gas monitoring, and fail to fully form monitoring, early warning, and control The integrated automatic monitoring and early warning system cannot fully monitor water inrush points and harmful gases during tunnel construction, so it cannot guarantee the safety of tunnel construction

Embodiment 1

[0042] See attached figure 1 , 2 As shown, this embodiment discloses an automatic monitoring and early warning system for groundwater and harmful gases during tunnel construction, including a monitoring and early warning vehicle, a control room and a linkage processing system. The monitoring and early warning vehicle includes an automatic walking module, a monitoring device and an early warning device. The monitoring device can detect the water content and harmful gas concentration in the tunnel through the built-in infrared thermal imager and gas detector, and will transmit a signal to the early warning device when the water content or harmful gas concentration exceeds the early warning threshold. The early warning device will provide different levels of early warning for water and gas according to the degree of risk, and send the signal to the control room. Relevant personnel will respond to on-site problems through the linkage processing system (including ventilation syste...

Abstract

The invention discloses an automatic monitoring and early warning system and method for underground water and harmful gas in the tunnel construction period. The system comprises a thermal infrared imager and a gas detector which are arranged on a mobile cart; when the water content or harmful gas concentration exceeds an early-warning threshold value, a signal can be transmitted to an early-warning device, and the early-warning device can carry out different-level early warning on water and gas separately according to the risk degree. The system integrates monitoring, early warning and control, gives out an alarm in time, achieves real-time alarm and remote alarm, can carry out real-time processing through a linkage processing system, and guarantees the normal construction progress of a tunnel and safety of workers.

Description

technical field [0001] The invention belongs to the technical field of monitoring during tunnel construction, and in particular relates to an automatic monitoring and early warning system and method for groundwater and harmful gases during tunnel construction. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Water inrush in tunnels has become one of the common problems in underground structure construction. Tunnel water inrush will cause corrosion of tunnel internal equipment and lining, thus hindering the normal construction process. In addition, the geological structure will be destroyed during the construction of the tunnel, and a large amount of gas and dust will be generated. Especially in the construction process of the underground tunnel, it is easy to damage the ground and cause the leakage of harmful underground gases. If the air...
