The objective of the invention is in order to overcome the deficiencies in the prior art, a kind of device that ponding in the Homofloor drainage system backfill layer can be got rid of is provided.

For realizing above-mentioned technical purpose, the invention provides a kind of accumulated water drainage device for drainage and backfill layers of same layer, it comprises shell and interior pipe, pipe is located in the shell that is embedded under the interior backfill layer bottom surface of floor in described, form drain chamber between shell and the interior pipe, bottom in drain chamber, interior pipe and enclosure closed make the drain chamber bottom end seal, be provided with drain hole near on the inner pipe wall of drain chamber bottom, and the open water inlet that forms in the top of drain chamber, interior pipe upper end has the last interface that connects drainage joint or house steward, and the lower end of shell or interior pipe has the lower interface that connects leader drain or drainage fitting.

For preventing that concrete stops up drain chamber in the backfill layer, be provided with sand proof net in the water inlet, sand proof net is clamped and is fixed between shell and the interior pipe by bilevel clamping plate.

In order to improve drainage effect, can also near the backfill layer bottom surface, lay the more piece gutter, gutter one end communicates with drain chamber, the other end can extend to the another side of backfill layer bottom surface, the gutter spaced surface be provided with a plurality of suctions hole so as the suction, flow for the deadweight that utilizes water is smooth and easy, gutter is to the drain chamber certain angle that tilts.Also can be in order to prevent that sand from entering gutter at gutter overcoat one deck sand proof net.

Can be provided with the one way valve that anti-sealing refluxes at the drain hole place, thereby pass back into drain chamber from drain hole when preventing that discharge is excessive in the house steward.

The present invention just can solve the ponding problem that backfill layer may occur in the Homofloor drainage system easily by increasing simple parts on the leader drain in floor, it is simple in structure, install also very convenient, and the syndeton compactness between leader drain and the joint, cost is lower, and also need not to do on backfill layer waterproofing course again.
