This invention discloses an integrated construction equipment and method for the subgrade material of a rockfill dam. The equipment includes an engineering vehicle 1, a paving and leveling mechanism 2, a hydraulic compaction mechanism 3, a follower vehicle 4, a traction frame 5, a cantilever mechanism 6, and a formwork mechanism 7. The engineering vehicle 1 drives the paving and leveling mechanism 2 at its front end forward, dispersing the subgrade material to both sides. Subsequently, the hydraulic compaction mechanism 3 at its rear compacts the subgrade material through high-frequency vibration. The follower vehicle 4, connected to the engineering vehicle 1 via the traction frame 5, moves synchronously. The cantilever mechanism 6 on the follower vehicle 4 erects the formwork mechanism 7 above the slope. The first formwork 72 of the formwork mechanism 7 supports the subgrade material working area, and the second formwork 73 supports the mortar layer, thus simultaneously completing the integrated operation of subgrade material paving, leveling, compaction, and slope mortar layer support. This construction equipment significantly improves construction efficiency, and through mechanized and precise control, it significantly enhances construction quality and safety.

The utility model discloses a safe sampler for anti-corrosion liquid, which comprises a hollow hand lever, a sealing cover and a container. One side of the lower end of the hand lever is connected with a container through a connecting block; a round hole is formed in one side of the upper end of the hand lever; a strip-shaped through hole A is formed in one side of the lower end of the hand lever close to the container; a through hole B is formed in the upper end of the hand lever; a pressing cap is inserted into the through hole B; a buckle structure is arranged at the lower end of the pressing cap; a movable rod is arranged at the lower end of the buckle structure; the upper end of the movable rod is sleeved with a spring. The lower end of the movable rod is connected with a rotating structure; the rotating structure penetrates through the through hole A and is connected with a sealing cover; and the sealing cover is matched with the container for use. According to the anti-corrosion liquid safety sampler, the sampling safety is improved, the operation convenience and the durability of equipment are ensured, and the anti-corrosion liquid safety sampler has higher practical value and market application prospect.
