The reusable tunnel lining plug template fixing device comprises longitudinal steel bars 1, circumferential steel bars 2, wooden wedges 3, steel pipe back edges 4 and square wood back edges 7. A plurality of longitudinal steel bars 1 are arranged, one end of a first longitudinal steel bar 1 is welded with a steel mould trolley 5, and a second longitudinal steel bar 1 is welded with a longitudinal main steel bar 99. The 2 steel bars are used as annular steel bars 2 and are respectively welded with the other ends of the longitudinal steel bars 1 to form a whole, and the main function is to transfer the force transferred by the back edges 4 of the steel pipes to the longitudinal steel bars 1. A steel pipe back ridge 4 is arranged below the circumferential steel bar 2, and a plug template 6 is fixed on the steel pipe back ridge 4 through a wooden wedge 3. The wooden wedges 3 are made by cutting wood and mainly act to transfer the force applied by the plug templates 6 to the steel pipe back edges 4. The steel pipe back edge 4 is a steel pipe with phi 48 mm and is arranged below the 2 annular steel bars 2 and mainly used for transmitting the force transmitted by the plug templates 6 to the annular steel bars 2. A square wood back edge 7 is arranged between the plug template 6 and the wood wedge 3, the square wood back edge 7 plays a role in transmitting force, the stress area is increased, and the damage of the plug template 6 is prevented. The end of the lining concrete 10 is completely plugged by the plug templates 6 by adopting the device, and then the concrete can be poured.
The application process comprises the following steps: taking the construction of lining concrete of a certain engineering tunnel as an example, the section of a certain diversion tunnel is U-shaped, the section size is 8.12 multiplied by 8.78m (clear width multiplied by clear height), the design flow is 95m < 3 >/s, the secondary lining of the tunnel is lined by C30 reinforced concrete, and the concrete thickness is designed according to the surrounding rock category condition and 0.3 m-0.7 m. The tunnel lining concrete is poured by adopting a steel mould trolley 5, the concrete is split along the axial direction of the tunnel, the length of each bin is 10.0m, and copper water stop is arranged between the split. Before lining concrete is poured, binding the steel bars, positioning a steel mould trolley 5 after acceptance inspection is qualified, plugging one side of the concrete end by adopting a plug template 6, and finally pouring concrete. Before the concrete end is plugged by the plug template 6, a fixing device of the plug template 6 needs to be prepared in advance. Firstly, arranging longitudinal steel bars 1, welding one end of each phi 12 steel bar to a steel mould trolley 5, wherein the length is 25cm, the welding interval is 50cm, the steel mould trolley is uniformly arranged along the periphery of the steel mould trolley 5, and the other batch of the phi 12 steel bars is uniformly arranged along the periphery of lining concrete, wherein one end of each phi 12 steel bar is welded to a main steel bar 9, the length is 25cm, and the welding interval is 50 cm; and then the 2 phi 20 circumferential steel bars 2 are respectively welded and connected with the other ends of the longitudinal steel bars 1. Preparing a plurality of wooden wedges 3 and steel pipe back edges 4, wherein the steel pipe back edges 4 are steel pipes with the diameter of 48 mm or 3mm, and each steel pipe is 1.0m long; when the plug template 6 is installed, the steel pipe back edge 4 is firstly installed below the 2 annular steel bars 2, the plug template 6 is fixed on the steel pipe back edge 4 by adopting the wooden wedge 3, the tightness of the template can be adjusted by knocking the upper part or the lower part of the wooden wedge 3 through a hammer, the whole lining concrete end is plugged by adopting the plug template 6 according to the method, and concrete can be poured after all plugging is completed. After the concrete strength reaches the design requirement, the formwork can be dismantled, firstly, the wooden wedge 3 is knocked, the plug formwork 6 is loosened, the steel pipe back edge 4 is dismantled, the end formwork is completely dismantled, the steel mould trolley 5 is removed, and the next-warehouse concrete pouring is performed in a reciprocating manner.
