⑤在对墩身、梁体进行洒水养护的同时，应对随墩身、梁体一起同条件养护的混

⑤ While sprinkling and curing the pier body and beam body, the concrete specimens cured under the same conditions along with the pier body and beam body should be sprinkled and cured so that the concrete strength of the specimen and beam body increases simultaneously. <br>⑶ <br>Check whether the gutter at the entrance of the tunnel is complete and smooth to prevent water from the hillside from collapsing into the tunnel; check whether the drainage ditch outside the tunnel is unobstructed to prevent water from pouring back into the tunnel during heavy rains; check the safety of the machinery and equipment outside the tunnel to prevent it from being washed away by heavy rains damage and personal injury. <br>⑷ Precast components in the prefabricated component production site <br>should be stacked in an orderly manner according to the production date to determine the maintenance period of the components; check whether the component products during the curing period are watered and covered, and the surface should always be kept moist during the curing period; they have finally set However, products that have not yet been demoulded should be stored in water for conservation.

⑤ While watering and curing the pier body and beam body, concrete specimens that are cured under the same conditions along with the pier body and beam body should be watered and cured, so that the strength of the specimens and beam concrete increases synchronously.<br>Tunnel<br>Check whether the gutter at the entrance of the cave is complete, unobstructed, and prevent the slope from flowing water and collapsing at the entrance of the cave; Check whether the drainage ditch outside the tunnel is unobstructed to prevent the catchment from flowing back into the tunnel in case of rainstorm; Check the safety of temporary rooms for machines, tools and equipment outside the tunnel to prevent rainstorm damage and personal injury.<br>(4) Prefabricated component production site<br>Prefabricated components should be stacked in an orderly manner according to the production date to determine the curing period of the components; Check whether the component products during the curing period are watered and covered, and keep the surface moist at all times during the curing period; Products that have already set but have not yet been demolded should be stored in water for maintenance.

⑤ While the pier and beam are maintained by water spraying, the concrete specimens that are maintained with the pier and beam under the same conditions should be maintained by water spraying, so that the concrete strength of the specimen and beam can increase synchronously.<br> (3) Tunnel<br> Check whether the roof gutter at the entrance of the cave is perfect and unobstructed, and prevent the hillside catchment from collapsing the entrance of the cave; Check whether the drainage ditch outside the hole is unobstructed to prevent rainwater from flowing backwards into the hole during the rainstorm; Check the safety of machinery and equipment in the temporary room outside the hole to prevent the damage caused by rainstorm and personal injury.<br> (4) Prefabricated component production site<br> Precast components should be stacked in an orderly manner according to the production date to determine the maintenance period of components; Check whether the component products in the curing period are watered and covered, and keep the surface moist during the curing period; Products that have been finally set but not demoulded should be stored in water for curing.
