The utility model has the advantages that:

1. the method is beneficial to improving the forming precision and quality of the concrete. The concrete meets the design strength before the member leaves factory according to the strict requirement of the mixing proportion (no admixture such as fly ash), the edges and corners of the member are clear, the surface is flat and smooth, and no quality defect exists, so that the forming precision and the forming quality of the concrete are effectively ensured.

2. And the method is favorable for really realizing zero leakage. The prefabricated caisson is produced on a production line, the mechanization degree is high, the raw material control is changed to the finished product delivery protection, the production procedure is standardized, and the human quality factors are reduced. The caisson adopts a reverse beating process, the falling plate surface is formed by a structural slope finding one-step, the secondary side floor drain opening is arranged at the slope, the water stored in the caisson can be completely discharged automatically, the water is closed before leaving the factory and the inspection and acceptance is qualified, and in addition, the concrete self-waterproof and waterproof layer is added, so that zero water stored and zero leakage at the bottom of the caisson can be really realized.

3. The construction period is shortened. The conventional method is that after the face steel bars are bound, the toilet plate-descending hanging die is installed, and the hanging die is hung on the face steel bars in the air, so that fixing is difficult, and more time is required to be consumed. After the prefabricated caisson is adopted, the formwork hanging installation is omitted in the sanitary room, the caisson hoisting and the plate surface reinforcing steel bar installation are carried out synchronously, the caisson hoisting is also installed in place after the plate surface reinforcing steel bar is finished, the inspection and acceptance can be carried out with the certainty, and the purpose of shortening the construction period is achieved.

4. Is beneficial to the operation of workers and the cultivation of industrial workers. The toilet hanging mould is suspended on the steel bars, so that no reinforcing stress point exists, and the toilet hanging mould can be completed only by consuming more time by professional aluminum mould workers. Adopt prefabricated caisson, only need pass through simple hoist and mount training, ordinary workman can accomplish the installation, reduces the building site to the reliance of aluminium mould skilled worker.
