Abstract
The utility model relates to a waterproof apparatus, concretely refers to a waterproof apparatus for tunnel construction, and solves the problems that waterproof performance is influenced by weld penetration and lack welding which easily happen to the conventional waterproof apparatuses. The waterproof apparatus for tunnel construction comprises a non-woven fabrics buffer layer fixed on a tunnel preliminary bracing surface, and waterproof boards disposed above the non-woven fabrics buffer layer, wherein suspension rings are welded on surfaces of the waterproof boards, and suspension belts penetrate the suspension rings and are fixed on the non-woven fabrics buffer layer through shoot nails. The waterproof apparatus for tunnel construction is reasonable and reliable in structural design; the suspension rings of the waterproof boards can be put in industrialized production to insure construction quality and to prevent the waterproof boards from being weld burnt or penetrated; and by using the apparatus, construction costs are lowered, using amount of thermoplastic plastics is greatly reduced, working efficiency is raised, and suspension time of the waterproof boards is shortened.
Description
Technical field
The utility model relates to water-tight device, is specially a kind of constructing tunnel water-tight device.
Background technology
The waterproof technique of existing tunnel construction adopts following method: at first; spread the nonwoven cushion coat in the preliminary bracing of country rock; then the upper unit of plastic of pad is fixed by ail gun; at last with unit of plastic and splash guard by the stickup of welding gun welderingization; leakageization burn-through, weldering leakage phenomenon usually can occur, and affect water resistance.
Summary of the invention
Burn-through easily occurs to the utility model in existing water-tight device, the problem that phenomenon affects water resistance is leaked in weldering in order to solve, and a kind of constructing tunnel water-tight device is provided.
The utility model is to adopt following technical scheme to realize: the constructing tunnel water-tight device, comprise the nonwoven cushion coat that is fixed on the Tunnel face, nonwoven cushion coat top is provided with splash guard, the surface soldered of splash guard has suspension ring, be installed with suspender belt in the suspension ring, suspender belt and nonwoven cushion coat are fixed by nailing.
During construction, basal plane is cleared up, directly hang the nonwoven cushion coat with the standby steel plate of high pressure ail gun, processing factory is welded the splash guard suspension ring outside the tunnel simultaneously, the splash guard suspension ring are hung oneself prepare and carry steel plate and be fixed at the nonwoven cushion coat with the high pressure ail gun, at last with the sweat soldering of two splash guard automatic creeping formula bonding machines, thin section processes or repairs and adopt hand torch, overcome existing water-tight device easily the leakage phenomenon affect the problem of water resistance.
The utility model reasonable in design is reliable, and the splash guard suspension ring can perform in batch production, guarantee construction quality, prevents from welding burnt burn-through splash guard; And reduced construction cost, greatly reduce the consumption with the thermoplastic packing ring; Improve simultaneously operating efficiency, shortened the time that hangs of splash guard.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1-nonwoven cushion coat, 2-splash guard, 3-suspension ring, 4-suspender belt, 5-nailing.
The specific embodiment
The constructing tunnel water-tight device, comprise the nonwoven cushion coat 1 that is fixed on the Tunnel face, nonwoven cushion coat 1 top is provided with splash guard 2, and the surface soldered of splash guard 2 has suspension ring 3, be installed with suspender belt 4 in the suspension ring 3, suspender belt 4 is fixing by nailing 5 with nonwoven cushion coat 1.
During basal plane is processed, the part leaks and adopts grouting for water blocking or bury the direct draining of gutter underground to the limit, and the projections such as steel mesh reinforcement cut off first and use afterwards hammer riveting flat wiping mortar element ash, when the pipeline of protrusion is arranged, floating with mortar, when anchor pole has the position of protrusion, after the 5mm cut-out is reserved on the spiral shell crown, process with plastic cap, preliminary bracing should be without hollowing, crack, crisp pastry, and the surface should be smooth-going, and concavo-convex amount must not surpass ± 5cm; In the specific implementation process, nonwoven cushion coat 1 is fixed by nailing with the Tunnel face, is lined with the steel plate washer of 2.5cm * 2.5cm between nailing and the nonwoven cushion coat 1; Suspension ring 3 adopt the waterproof lath of long 15cm, wide 2cm, it are welded by the requirement of design suspension centre with hot air welding gun, at first weld an end pad, then with on the preprepared suspender belt (cloth bag, cotton cord), weld at last other end solder joint.
