[0021] Example 1
[0022] A construction process for the discharge pipe of a high-speed rail bridge includes the following steps:
[0023] (1) Install the mold corresponding to the reserved hole of the discharge pipe on the template fixed by the prefabricated beam combination; the size of the reserved hole of the discharge pipe is 280~320×300~320mm.
[0024] (2) Use PVC pipes to bury the holes, ensure that the embedded holes are vertical, pour concrete, and after curing for 26 days, remove the mold for the holes reserved for the drain pipe;
[0025] (3) Cut out the PVC pipe, cut out the installation groove on the top of the bridge deck, put the drain pipe into the hole, and fix the drain pipe; use the grouting material to seal the surrounding wall of the drain pipe and the installation slot; specifically, the water After mixing with the grouting material according to the mass ratio of 5:1, the mixed slurry is obtained, which flows into the gap between the drain pipe and the bridge fro...
