[0023] For the steel structure bridge, after milling the asphalt layer, the steel structure corrosion prevention treatment is carried out, a layer of water sealing asphalt lower layer 3 is paved first, the vertical water permeable pipe 7 and the horizontal water permeable pipe 8 are buried on one side of the bridge curb 5, the tee pipe fitting 19 is connected, and then the rainwater is drained to the drainage well 9 through the spiral drainage pipe 10, the water permeable asphalt upper layer 4 is used at the top, so that the rainwater can be permeated and drained to the spring water permeable pipe; for the water seepage problem of the underpass interchange, after milling the surface layer asphalt, a layer of water sealing asphalt lower layer 3 is paved first, the groove 6 is opened at the water seepage point, the horizontal water permeable pipe 8 is buried on one side of the bridge curb 5, and the water seepage is directly drained to the drainage ditch beside the interchange through the horizontal water permeable pipe 8, so as to reduce the influence of road water seepage on the road structure layer and the asphalt layer.

[0024] As an embodiment, as shown in Figure 1 and Figure 4 The tee pipe fitting 19 includes a connecting seat 11, the connecting seat 11 is provided with three inlet ends, the inlet ends are respectively connected with a group of horizontal water permeable pipes 8 and two groups of vertical water permeable pipes 7, and a pre-buried bottom plate 14 is fixedly installed at the bottom end of the connecting seat 11; a water storage bin 13 is arranged in the connecting seat 11, an opening 16 corresponding to the inlet of the connecting seat 11 is formed in the outer portion of the water storage bin 13, a water filter net 15 is arranged in the inner portion of the opening 16, a plurality of expansion covers 17 are slidably installed on the outer portion of the water storage bin 13, adjacent two groups of expansion covers 17 are arranged on the two sides of the opening 16, springs 18 are connected between the expansion covers 17 and the water storage bin 13, and inlet clamps 12 corresponding to the expansion covers 17 are fixedly installed at the inlet ends of the connecting seat 11.

[0025] Among them, the expansion cover 17 is arc-shaped, and one end of the plurality of expansion covers 17 is obliquely arranged.

[0026] Among them, the water storage bin 13 is in a spherical structure, the cross section of the opening 16 is in a trapezoidal shape, and the opening 16 is in communication with the water storage bin 13.

[0028] In this embodiment, when installing, a set of horizontal water permeable pipes 8 and two sets of vertical water permeable pipes 7 are installed in the connecting seat 11, the expansion cover 17 in the connecting seat 11 expands on the inner side of the spring water permeable pipe under the elastic force of the spring 18, and at the same time, the connection is made by cooperating with the import clamp 12 to improve the firmness of the connection and enhance the stability; when rainwater and dirty water penetrates into the horizontal water permeable pipe 8 through the water permeable asphalt upper layer 4, the internal dirty water flows to the connecting seat 11 through the slope at the bottom of the groove 6, is blocked by the water filtering net 15 in the water storage bin 13, prevents the silt from being blocked, flows into the next vertical water permeable pipe 7 through the opening 16, and finally flows into the drainage well 9 through the spiral drainage pipe 10.
