The utility model provides a water pervious frame formed at one time. The water pervious frame formed at one time comprises rod pieces which comprise the first rod pieces and the second rod pieces. The three first rod pieces are connected end to end to form an equilateral triangle structure which forms the lower structure of the water pervious frame, and the triangular structure has stability. One second rod piece is arranged at the connecting position of every two first rod pieces, one end of each second rod piece is connected with the corresponding first rod piece, the other end of each second rod piece is connected with the other two second rod pieces, the three second rod pieces are matched with one another to form a tripod structure. The first rod pieces and the second rod pieces are matched mutually to form a triangular pyramid structure. The water pervious frame formed at one time can be prevented from being damaged due to the fact that the reinforcing steel bar welding positions of the four-face six-edge water pervious frame are extremely easy to rust, reduces the damage rate of components in a project using process, improves manufacturing and construction efficiency of the components, and meets needs of project duration.
