Anti-flooding technology for ground pavement of backfill field

The invention discloses a backfill field ground paving anti-flooding process, which comprises the following steps of: surveying on site, scribing, marking vertical driving point positions on backfill, marking inclined point positions on the periphery of the backfill, and arranging the vertical driving point positions and the inclined point positions along a matrix and corresponding to each other; calculating the number of materials of the required prefabricated rectangular support piles, hollow anchor rod assemblies and reinforcing meshes according to the measured data; and a pile machine enters the field, and high-pressure water flow is sprayed in the middle of the prefabricated rectangular support pile through a high-pressure jet grouting rod to cut the inclined hole. A structure composed of the prefabricated rectangular supporting piles, the hollow anchor rod assemblies and the reinforcing meshes serves as a backfill soil field foundation, construction is convenient, the bearing resistance is high, and col
