The upper surface of described bottom seal ring is close on the bottom surface of cement mortar.
The upper surface of described floor drain is than the low 2mm～3mm of upper surface of surface layer.
Be filled with fluid sealant between described floor drain and the surface layer.
A kind of job practices of Novel anti-seepage floor drain system, it is characterized in that step is as follows: step 1, in the construction reinforced bar concrete floor, preformed hole is set, namely before the top board reinforcing bar binding, press the floor drain on the drawing, the position of water supply and sewerage pipeline, paint at the floor template subscript and draw, during the floor bar colligation, the physical location of floor drain, water supply and sewerage pipeline stayed allow out, the strong, weak electricity preheating embedding line is avoided the position of floor drain, water supply and sewerage pipeline, fixes hole before the concreting and reserves instrument.
In the described step 2, in the upper port 3cm of distance sewer pipe～bonding bottom, 5cm place seal ring, make the bottom seal ring be close to reinforced concrete floor lower plane absolute altitude.
In the described step 9, when floor drain is installed, the low 2mm～3mm of upper surface of the ratio surface layer that the upper surface of floor drain is installed.
In the described step 9, when floor drain is installed, be between floor drain and surface layer filling with sealant.
Compared with prior art the present invention has following characteristics and beneficial effect: the present invention is applied to the floor drain draining field of PVC material in the construction work washroom, to have carried out improved a kind of floor drain drainage system on the basis of omitting traditionally water system in printing, its result of use is good, make simple, easy construction, can save a large amount of manpower and materials, can accomplish that waterproofing course is received head end to be covered comprehensively, avoided on the waterproofing course because long-term the use, the water that accumulates can along the possibility of waterproof weak spot infiltration, have been realized the perfect combination of waterproof and draining.
