The utility model provides a novel approach road structure, including the U -shaped groove, its structure is: U -shaped tank bottom portion passes through linking beam and connects the anti stake of floating, and U -shaped tank bottom portion is equipped with and the anti stock that floats stake parallel arrangement, linking beam for the dark roof beam of embedding U -shaped tank bottom inboard, the inside pillar that is equipped with of stock, outsidely be the anchoring body, be provided with the reinforcing bar in the pillar. Through above -mentioned structure, the utility model discloses relying on frictional resistance and the dead weight of structure between drilled pile, stock and the foundation soil to resist water buoyancy jointly, having solved high underground water level, super wide U -shaped approach road structure adopts the anti problem that can not meet the demands of floating of conventional method, the anti ability of floating is given first place to with the drilled pile, and the stock is the assistance for the structure is more reasonable, has reduced the cost, and for engineering of the same kind provides the reference, social and economic benefits are showing.
