The invention relates to the technical field of crop planting ground surface draining water collecting, and particularly relates to a shallow groundwater seepage flow water collecting underground pipestructure. The structure comprises a water collecting blind ditch which is arranged below a crop planting soil layer, the water collecting blind ditch is sequentially paved with a coarse sand layer,an intermediate sand layer and a fine sand layer from bottom to top, the coarse sand layer is provided with water collecting underground pipes which are distributed in gradients, the water collectingunderground pipes comprise main pipes and branch pipes and capillary pipes which are communicated with the main pipes, the diameter of the main pipes is greater than the branch pipes, the diameter ofthe branch pipes is greater than the capillary pipes, water collecting holes are uniformly formed in the pipe walls of the capillary pipes and the branch pipes, the ends with the lower positions of the capillary pipes are communicated with the branch pipes, the ends with the lower positions of the branch pipes are communicated with the main pipes, water in the capillary pipes flow into the branchpipes and gather and enter the main pipes, and the lower ends of the main pipes are provided with a water storage tank. The structure has the advantages that underground water can be prevented from gathering on the bottom layer of soil to inhibit the upward evaporation transferring of the underground water carrying salts, namely the further deterioration of soil salt-alkalizing is relieved, the underground water which is collected in the water storage tank can be used for irrigation at any time, and the controllable recycling of water resource is achieved.
