Description

Accumulated water remover

Technical Field

The utility model relates to a building is with layer drainage field, in particular to ponding excluder.

Background

The drainage of the same floor of the building means that the drainage horizontal pipes of the same floor do not penetrate through the floor slab and are connected to the drainage vertical pipes in the same floor. If the condition that needs clearance mediation takes place, can solve a drainage mode of problem in this layer cover promptly. Compared with the traditional interlayer drainage mode, the most fundamental idea change of the same-layer drainage scheme is that the constraint between adjacent floors is thoroughly eliminated through reasonable arrangement of pipelines in the same layer, and a series of troubles and hidden dangers caused by the fact that a drainage transverse pipe occupies the space of the lower layer are avoided.

In order to realize the same-floor drainage, a drawdown type same-floor drainage or a different drawdown type same-floor drainage is generally adopted. In the lowering plate type same-floor drainage scheme, a sedimentation box is generally adopted, horizontal drainage pipes of water appliances such as wash basins, showers, bathtubs, toilets and the like are paved in the sedimentation box, the horizontal drainage pipes are connected with vertical drainage pipes penetrating through a floor slab to a lower-floor household space, then a filling layer is filled in the sedimentation box and is formed, the filling layer is positioned above a concrete layer of a cast-in-place floor slab, and a waterproof layer and a floor tile layer are arranged above the filling layer.
