Description
Technical Field
The invention belongs to the technical field of tunnel construction, and relates to a plug template for secondary lining of a tunnel.
Background
The existing highways and railways are usually built by adopting a new Otto method, and in the construction of tunnels, a concrete tunnel protection layer with the thickness of about 370mm is further poured after the tunnel is excavated, and a trolley is equipment used for pouring concrete in tunnel construction. At present, the secondary lining of tunnels is mostly constructed by adopting a lining trolley mould construction method, and in order to prevent leakage of seam repair in each piece of secondary lining construction, a buried rubber water stop is designed and installed at the end of each secondary lining. When the trolley is adopted to pour the secondary lining, a plug board is needed to be used for closing the mould between the template trolley and the surrounding rock, and the problem of placing the embedded water stop and the problem of exposing the inner ring steel bars and the outer ring steel bars are needed to be treated during closing the mould, so that the mould closing is complex. In the prior art, most of plugs of the two lining trolleys are assembled by adopting wood boards, one side of the template trolley is provided with a plug board, the plug board is limited by tunnel environment, and conventionally, temporarily assembled narrow battens with fixed annular directions and different lengths are often adopted as the plug board. This approach has a number of problems: the working mode of paving the wood board plugs at the end parts of the template trolley has large workload (the workload of paving a circle of wood board plugs usually needs 4 people for 8 hours), and the mould is also troublesome to withdraw; not only is a large amount of wood wasted, the repeated utilization rate of the wood is low, but also a large amount of holes and leakage points are easy to exist due to poor mold closing effect of the wood, particularly, the positions of the steel bars are not easy to seal, other soft objects are needed to be adopted to block the holes in the later period, and even so, the problem of cement paste leakage and waste cannot be avoided; the wood board is adopted to close the mould, and the joints of the plug boards are too many, so that the installation of the embedded water stop is very inconvenient, and the embedded water stop needs to be folded along the wood board so as to be closed in the mould, thus the problem that the position of the water stop is misplaced between the adjacent secondary lining pouring models is easily caused, and the due water stop effect cannot be achieved; the edges and corners of the wood boards are easy to damage waterproof boards under waterproof surrounding rocks, so that hidden danger of leakage of water and slurry in tunnels is caused. Of course, the prior art also has the technical proposal of using the steel template as the end-mold plug, but has the defects of heavy template, difficult operation and the like. For example, the utility model patent 'a tunnel secondary lining template trolley plug board' (application number: 201520472105.7) provides a plug board arranged on a template trolley, a water stop belt is fixed through the plug board, and closing and blocking are carried out, but the design is complex, and meanwhile, the problem that a dew reinforcement is not easy to bypass exists.
Because in the secondary lining, in order to prevent the dislocation of the concrete poured in front and back twice from influencing the waterproof performance of the secondary lining, the hidden danger of tunnel water leakage and slurry leakage is caused, a section of reinforcing steel bar needs to be reserved at the end part of the concrete poured in the previous section, the acting force between the concrete poured in front and back twice can be effectively improved through the reserved section of reinforcing steel bar layer, and the dislocation and fault are prevented. However, due to the existence of a reserved section of steel bar, the installation of the template is affected no matter a wood board or a steel template is used as an end mould plug, and the problems of mould closing tightness and mould closing effect exist. Therefore, technicians usually cut off the reserved steel bars when actually working, so that the installation of the wood boards or the steel templates is inconvenient, and finally the water leakage and slurry leakage of the existing tunnel are serious.
