Problems solved by technology
When using the grouting port to pour concrete, because the pouring situation cannot be observed, if the pouring is small, it is easy to form a cavity at the top and the ring joint, but if the pouring is too much, due to the high pressure of the concrete pump, it is easy to burst the grout or even damage the lining Therefore, there is an urgent need for a system that can realize real-time monitoring of tunnel construction

The invention relates to the field of construction monitoring systems, in particular to a secondary lining belt mold grouting monitoring system. The system is used for monitoring the concrete pouringprocess of a tunnel lining trolley, the trolley is provided with a working window, and the secondary lining mold grouting monitoring system comprises a main camera, a monitoring device and a fixing device; the main camera is connected with the monitoring device, and the monitoring device is used for displaying images captured by the main camera; the main camera is connected to the fixing device, and the fixing device is connected to the trolley; the main camera can cooperate with the working window on the trolley. Through the secondary lining belt mold grouting monitoring system, during the construction process, the images captured by the main camera through the working window are transmitted to the monitoring device, and construction personnel can monitor the construction condition in theworking window through the monitoring device, thereby achieving real-time monitoring of the secondary lining belt mold grouting process.
Description
technical field [0001] The invention relates to a construction monitoring system, in particular to a monitoring system for secondary lining with mold grouting. Background technique [0002] Tunnel construction is generally divided into excavation, initial support, shotcrete anchoring, secondary lining and other processes. The construction of secondary lining is mostly carried out by tunnel lining trolley, and the sequence of pouring concrete for secondary lining construction is from bottom to top. Left and right balance, because the lining trolley and the excavated surrounding rock form a closed space, the inward pouring of concrete at the bottom and both sides is through the working window on the trolley, and finally through the grouting port set on the top of the trolley. When using the grouting port to pour concrete, because the pouring situation cannot be observed, if the pouring is small, it is easy to form a cavity at the top and the ring joint, but if the pouring is t...
