| Abstract: | Through the Kai-Luo highway whose width is 64.5 m, nine work wells and eleven road bases, the holes are drilled. Base on the shape of the road surface, the trail of drilling hole is curve . Its ends are lower and the middle part is higher. Then the diameter of holes is extended to 500mm step by step. Four pipes of 114 mm and three pipes of 60 mm are laid. The distance between the two bundles of pipe is 450 mm and it satisfies the request of the design. |
