When the assembled waterproof toilet chassis is applied to newly built buildings or old houses for reconstruction, a supporting piece is placed on a structural floor slab which is not leveled and is not waterproof (or on the ground of the structural floor slab which is leveled or is waterproof), an infrared level meter is adopted to adjust the top surface of the supporting piece to enable the top surface of the supporting piece to be close to the same horizontal plane, then a polyurethane foam filling cushion layer is sprayed and filled on the structural floor slab, when the polyurethane foam cushion layer is sprayed and filled, under the condition that the polyurethane foam is not fully expanded, the local expansion thickness exceeds the top surface of the supporting piece, then the bottom surface of the chassis body is placed on the top surface of the supporting piece, the surface of the waterproof flanging of the chassis body is the same plane, one end of a chassis fixture is

layer is arranged below the chassis body, so that a structural floor slab does not need to be additionally provided with the waterproof layer, certainly, if the chassis fixture is not provided with an aluminum strip hook, only screws or other cushion plates are arranged, other similar modes can be adopted for automatic dry leveling of the chassis body, in addition, after the polyurethane foam is completely expanded, the chassis fixture can be detached and discarded, the fixture can be screws, quick-drying glue, cushion blocks or polyurethane foam objects, for example, after the chassis is placed and the position of the chassis is adjusted, the cushion blocks can be plugged between the waterproof flanging of the chassis and the structural wall surface, friction force is formed between the cushion blocks and the outer surface of the waterproof flanging of the chassis and the structural wall surface, so that the cushion blocks are the chassis fixture, and when the polyurethane foam is extruded upwards from a gap between the waterproof flanging of the chassis and the structural wall surface, because the extruded part can be quickly cured after being contacted with air, the polyurethane foam of the extruded part is cured, the polyurethane foam at the bottom of the chassis body is not cured, the cured polyurethane foam can restrain the chassis body and the structural floor slab, and the polyurethane foam of the quickly cured part can also be a chassis fixture, and the like; the construction process for installing the chassis body is simple by the several modes,
