Manual construction of reinforcement cages in the pavement trenches, construction in the reinforcement cages in sections to support the reinforcement cages for the partition wall, after the completion of the reinforcement cage construction for the partition walls, install the reinforcement cages for the pavement to waterproof trenches in sections and install the model of road surface to waterproof trenches (6) , the reinforcement cage for the construction partition wall between two adjacent models, and the model with permeable holes prefabricated between two adjacent models; The model of the roadside improvement reservoir (8) is installed in sections in the reinforcement cages on both sides of the U-shaped road surface groove, and the reinforcement cage of the partition wall is constructed between the adjacent two models, and the prefabricated between the adjacent two models The model of the permeable hole; after the installation of the models of the road surface changing waterproof groove (6) and the roadside changing water storage tank (8) is completed, there will be a U-shaped cavity between the model and the road surface changing waterproof groove and the water storage tank groove respectively , concrete is poured in the U-shaped cavity and the bottom manually, and the model after the concrete pouring is solidified is demoulded by manually removing the model, and the U-shaped road surface groove after demoulding forms the road surface improvement waterproof groove (6), road Renovate the side storage tank (8); the upper end of the rainwater lifting pipe (16) reserves a drainage outlet corresponding to the roadside changing storage tank (8) and installs it manually; 6), the mouth of the roadside water storage tank (8) is manually installed with the shade cover (6-2); after the shade cover (6-2) is installed, the lower crossing highway section (3) of the horizontal highway (2) is installed. ), passing through the road slope section (4), the slope top waterproof belt (9), and the road surface waterproof slope (10) for road surface construction. 5. A kind of construction method of passing through the slope of the highway according to claim 1 and rebuilding the waterproof groove, it is characterized in that: when the continuous precipitation in rainy days is large, the rainwater at the two ends of the transverse road (2) passes through the road surface to improve the waterproof groove ( 6), the roadside is changed into a water storage tank (8) to collect, and the rainwater is drained through the roadside rainwater pipe (14); the rainwater passing down the road slope section (4) passes through the slope into a water tank (5), and passes down the road section ( 3) The rainwater is collected through the bottom ditch (7), and the rainwater collected by the slope improvement waterproof groove (5) and the bottom ditch (7) is discharged into two pairs of underpassing road rainwater collection pools respectively through the roadside rainwater pipes (14) (11), under the road rainwater collection pool (11) through the lifting pipe of the submersible pump (12) to carry out lifting and drainage, and the lifting drainage rainwater enters the roadside to change the storage tank (8) and then passes through the roadside rainwater pipeline (14) Drainage, the rainwater discharged by the roadside rainwater pipe (14) is discharged into nearby river courses.
