The utility model relates to a supporting construction's technical field discloses anti -floating pile, lattice column and trinity structure of precipitation well among supporting construction, including setting up anti -floating pile and the lattice column in the stake hole, the lower extreme of lattice column is inserted and is established in anti -floating pile, and extend towards the drill way in stake hole the upper end of lattice column, forms vacant section, the outer parcel of vacant section of lattice column has wire net and a close mesh filter screen, the wire net with it forms the precipitation well to enclose between the lattice column to close. The utility model discloses an anti -floating pile, lattice column and trinity structure of precipitation well among supporting construction has following advantage: 1 ), the single pile is multi -purpose, 2 ), reduce drilling pore -forming quantity, simplified construction flow, improved the efficiency of construction, 3 ), construction quality easily controls, 4 ), reduce construction cost, 5 ), the deployment of industrial area ground, scope of operation flowing water construction arrangement be favorable to executing, 6 ), it is energy -concerving and environment -protective.
