An inlet hole is provided at the bottom end of the middle part of the water pond. A filter layer is provided in the inlet hole. A baffle is provided at the top end in the inlet hole. The baffle is provided with dense small holes. A plurality of drain holes are respectively provided at the four circumferences of the bottom of the water pond. A plurality of drain ditches corresponding to lead to the plurality of drain holes are respectively provided around the circumference of the bottom of the water pond around the inlet hole. Each drain ditch gradually inclines from one end close to the inlet hole to the other end, and the inner diameter gradually increases. The structure of the utility model is simple, and it avoids the accumulation of impurities such as feces in the middle of the water pond and causes blockage.

[0004] In view of the above related technologies, it is found that the pool wall of the existing aquaculture pond adopts an integrally cast and formed structure, which not only has a relatively high construction difficulty, but also has a relatively high construction cost.

The concrete base is laid and fixed on the upper end surface of the cushion layer, and a number of FRP angle steels for limiting the lower end of the pool wall part are installed inside the concrete base. The FRP angle steels are fixedly connected with the concrete base. The pool wall part is formed by stacking a number of layers of annular pool walls, and each layer is composed of a number of FRP thin plates. The FRP thin plates are fixedly connected through a sealing component.

[0008] As a preferred solution, the sealing component includes an inner node plate and an outer node plate. The inner node plate and the outer node plate are respectively arranged on the inner and outer sides of the connection gap of the FRP thin plates, and the inner node plate, the FRP thin plates and the outer node plate are fixedly connected to each other through bolts.
