The utility model relates to the technical field of house building construction, in particular to a concrete slurry leakage anti-pollution device which comprises a flow guide plate and a supporting column, a connecting piece is arranged on one side face of the flow guide plate, the supporting column comprises a vertical section and an inclined section, a bottom plate is arranged at the bottom of the vertical section, and the top of the vertical section is connected with the inclined section. And the inclined section is detachably connected with the connecting piece. According to the concrete slurry leakage anti-pollution device, the flow guide plate is supported by the supporting column with the bottom plate, so that the flow guide plate can be obliquely arranged below the joint to guide slurry leaked from the joint, the slurry is prevented from flowing downwards along the wall surface to pollute the wall, the process of manually shoveling slurry residues is avoided, and meanwhile, the construction efficiency is improved. And the flow guide plate can be supported by adopting the supporting columns with different heights according to the joint position, so that the flow guide plate can be arranged quickly, and the arrangement efficiency of the anti-pollution device can be improved.

An adaptive slope laser emitter for tunnel floor construction surveying includes an adjustment mechanism on the upper surface of a leveling base. A frame is connected above the adjustment mechanism, and a digital tilt measuring device is installed within the cavity on the front of the frame. A rectangular slot is located at the top of the frame, and a laser emission module is installed within the slot. The adjustment mechanism can adjust the vertical angle of the frame and the laser emission module within a range of 0 to 90 degrees. During tunnel floor excavation and foundation clearing or concrete pouring and formwork erection, the adjustment mechanism, in conjunction with the digital tilt measuring device, adjusts the tilt angle of the laser emission module to the designed slope of the tunnel. The 360-degree annular light band emitted by the laser emitter on the laser emission module illuminates the tunnel sidewall, forming a uniform light band. On-site construction personnel use this uniform light band, along with measuring rods, to determine the excavation, backfilling, or formwork erection elevation, continuously establishing road elevation benchmarks and improving work efficiency.
