A road sub-surface structure having pipe equipment is provided to drain water on the concrete paved layer and to prevent the road from being corroded by first and second connecting pipes and first, second, and third water passages. A road sub-surface structure having pipe equipment comprises a support net(200), and a pressing device(100). The support net has water flow pipes having a plurality of inlets. The pressing device has a body(110) and an elastic pressing rod(120). Second connecting pipes(153) are communicated with the water flow pipe. First connecting pipes(152) are communicated with perforated pipes(70). A sewer(151) is communicated with a drain pipe(80). The pressing rod has a cylinder engaged with a supporting piston. An elastic pressing member is installed at the lower surface of the pressing rod. Two sides of a first water passage are communicated with the sewer. A second water passage is communicated with the first connecting pipe. A third water passage is communicated with the second connecting pipe. |
