Problems solved by technology
[0005] The purpose of the present invention is to solve problems such as cracking and falling off of the arch in the tunnel, repairing and falling off, knocking sound, leaking water, gouging and repairing falling off, water gushing and other diseases, which seriously threaten the driving safety. The problem seriously delayed the opening, which had a serious impact on operation and safety, and caused huge economic losses. However, the proposed tunnel vault anti-evacuation early warning device and its concrete real-time monitoring method

Embodiment 1
[0040] according to Figure 1-6 , the tunnel vault anti-void early warning device and its concrete real-time monitoring method include the following steps;
[0041] Step 1. Leveling the initial support of the tunnel: When the tunnel excavation is under-excavated, carry out secondary drilling and supplementary shots, and excavate the under-excavated part to the design contour line. When the tunnel excavation is over-excavated, use the same grade of concrete backfill Dense, after the initial support is completed, use a 1m ruler to check the surface flatness of the initial support. The flatness of the initial support surface meets the requirements of D / L≤1 / 10 (D is the adjacent two convex and concave surfaces of the initial support base surface. The depth of entry; L is the distance between the two adjacent convex surfaces of the base, and L≤1m), if it does not meet the requirements, it should be treated with shotcrete or chiseled concrete;
[0042] Step 2: Laying and hanging th...

The invention discloses a tunnel vault anti-void early warning device which comprises a grouting vehicle and a primary building trolley end mold, and the grouting vehicle is provided with a sewage treatment system, a monitor and an effect evaluation system. According to the tunnel vault anti-void early warning device and the concrete real-time monitoring method and the real-time observation process thereof, the tunnel lining arch self-alarm anti-void construction technology based on the cloud video technology is adopted, in the construction process, the secondary lining procedure and the grouting procedure basically belong to parallel procedures, grouting can be completed immediately while secondary lining is completed, and the construction efficiency is improved. The problem of grouting pipe blocking does not exist, meanwhile, the secondary lining pouring and filling grouting conditions are observed in real time through the cloud video technology, the tunnel vault disengaging prevention early warning is utilized, the tunnel vault concrete pouring compactness condition is checked, an alarm is given in time, vault disengaging is effectively prevented, the tunnel lining construction quality is improved, the lining construction defects are overcome at a time, and the construction efficiency is improved. The method has obvious comprehensive economic benefits, and can greatly save later-stage cost.
Description
technical field [0001] The invention relates to the technical field of tunnel lining construction, in particular to a tunnel vault anti-vacation early warning device and a concrete real-time monitoring method thereof. Background technique [0002] Tunnels are engineering structures buried in the ground, and it is a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels. The structure of the tunnel includes the main building and auxiliary equipment. The main building is composed of the body and the door, and the auxiliary equipment includes a car shelter , fire protection facilities, emergency communication and drainage facilities, long tunnels also have special ventilation and lighting equipment. [0003] In recent years, tunnel construction has entered a stage of high-speed development. With the continuous increase of the total length of railway tunnels, my coun...
