Description

Technical Field

[0001] The invention relates to the technical field of tunnel engineering, in particular to a tunnel assembled structure deformable prefabricated template. Background Art

[0002] As highway construction continues to deepen, a large number of tunnels have been transformed from new construction to operation. As the service time of tunnels increases, design and construction defects gradually emerge, and highway tunnel diseases are widespread. The emergence of diseases such as cracking, water seepage, and block falling can damage the visual appearance and distract drivers, or even cause safety accidents, resulting in serious economic losses and social impacts. In view of the current status of diseases, how to quickly treat them after discovery has always been a research hotspot;

[0003] When manufacturing existing lining segments, concrete is often poured into a mold and then left to solidify. If the concrete solidifies directly, a small amount of bubbles will exist in the concrete, resulting in lower strength and shorter service life of the lining segments.

[0004] For example, the patent with publication number CN 108501187 A discloses a deformable prefabricated template for an assembled structure of an operating diseased tunnel, comprising a base, a hollow arc-shaped bracket arranged above the base, and a bottom mold arranged above the hollow arc-shaped bracket to form an arc-shaped block structure, two split cover molds or a side single-open cover mold, two side molds and two end molds; a plurality of electrically controlled hydraulic telescopic rods are arranged between the bottom mold and the base; the cover mold comprises an outer steel plate, an inner steel mold and a plurality of electrically controlled hydraulic telescopic rods arranged therebetween, and one side of the cover mold is rotatably arranged on a hollow sleeve inclined outward through a rotating shaft;

[0005] However, when the above patent is in use, concrete needs to be injected into the arc-shaped block structure and then the cover mold is covered. However, when the side mold is replaced, the size of the side mold changes, and the cover mold may not be able to completely cover the entire arc-shaped block structure. When the electric-controlled hydraulic telescopic rod controls the movement of the inner steel mold, concrete may flow out from the part that the cover mold cannot cover, resulting in an abnormal shape of the final lining segment and a low yield.
