[0002] With the increasing demand for large-scale water conservancy and transportation infrastructure construction in China and even the world, traditional tunnel construction technologies show limitations such as low construction efficiency, high safety risks, and difficult quality control when facing ultra-large cross-section sizes. Therefore, it has become an urgent task to develop an intelligent device that can adapt to ultra-large structural sizes and has high-efficiency automated construction capabilities.

[0003] A Chinese invention patent with the publication number CN111396093A was published on July 10, 2020.

After waiting for solidification and forming, the manipulators 15 contract and the base support adjusting screw rods 1 contract to leave the formed concrete, and the traveling wheel boxes 2 move the cloud vehicle to the next forming position to expand and continue the operation, solving the problem that the existing tunnel lining vehicle cannot be deformed and adapted according to the inner contour surface of the tunnel.

[0024] There are multiple intermediate small columns 8 and end small columns 9 fixedly connected between the template unit 7 and the upper longitudinal beam 10; on both sides of the upper surface of the upper longitudinal beam 10, end small columns 9 are symmetrically arranged; between the end small columns 9, there are multiple intermediate small columns 8; during operation, through the support and fixation of the intermediate small columns 8 and the end small columns 9, the template unit 7 can fit with the inner contour surface of the tunnel to form a pouring space, thus facilitating the pouring of concrete to solidify and form, solving the problem that the existing tunnel lining vehicle cannot be deformed and adapted according to the inner contour surface of the tunnel.

[0025] There are multiple diagonal rods 14 detachably fixedly connected between the support columns 13 and the column cross beam 12; during operation, by connecting the support columns 13 and the column cross beam 12 through the diagonal rods 14, the connection strength between the support columns 13 and the column cross beam 12 is greatly increased, so that large deformations will not occur during use, making the use more precise.
