New anti-seepage floor drain system and its construction method

Abstract

The invention discloses a novel anti-seepage floor drain system and a construction method thereof. The system comprises a reinforced concrete floor slab, a leveling layer, a water-proof layer, a water-proof protective layer and a surface layer and a floor drain, wherein the reinforced concrete floor slab is provided with a preformed hole; the leveling layer, the water-proof layer, the water-proofprotective layer and the surface layer are arranged on the upper surface of the reinforced concrete floor slab in turn from the bottom to the top; the floor drain is arranged in the preformed hole and is communicated with a sewer pipe made of a polyvinyl chloride (PVC) material; a diameter-changing funnel made of the PVC material is arranged in the preformed hole of the reinforced concrete floor slab; a lower water stop ring made of the PVC material is bonded between the lower end of the diameter-changing funnel and the outside wall of the sewer pipe by using PVC special glue; a PVC pipe is placed in the diameter-changing funnel; an upper water stop ring made of the PVC material is bonded between the upper outside wall of the PVC pipe and the upper end of the diameter-changing funnel by using the PVC special glue; and the head end of the water-proof layer is extended to the upper inside wall of the PVC pipe. The floor drain system is convenient to construct, can save a large amount ofmanpower and material resource, avoids the possibility that accumulated water can penetrate along a water-proof weak pocket because the water-proof layer is used for a long time, and realizes the perfect combination of water prevention and water discharge.

Description

technical field [0001] The invention relates to a floor drain drainage system made of PVC material used in construction engineering and a construction method thereof. Background technique [0002] The floor drain drainage system is an important interface connecting the drainage piping system and the indoor ground, and is an important part of the indoor drainage system in industrial and civil buildings. In industrial and civil buildings, water seepage in the floor drain drainage system has been a common quality problem in the construction industry for many years, and it is also a major problem in the construction industry. According to many years of construction experience, we found that the main reason for water seepage is that the installation height of the floor drain is higher than the height of the waterproof layer. Weak points seep water, thus affecting the waterproof effect of the floor. After the floor drain drainage system seeps, it will increase the difficulty of ...
