The pre-embedded drainage device comprises an upper shell and a lower shell, the upper shell is connected with the lower shell, a drainage cavity and a ventilation cavity are formed in the lower shell, a partition plate is arranged between the drainage cavity and the ventilation cavity, a lower drainage vertical pipe connecting hole is formed in the lower portion of the drainage cavity, and a lower drainage vertical pipe connecting hole is formed in the lower portion of the ventilation cavity. A lower ventilation vertical pipe connecting hole is formed in the lower part of the ventilation cavity; an upper three-way pipe connecting hole and an upper ventilation vertical pipe connecting hole are formed in the upper shell, the upper three-way pipe connecting hole is located above the drainage cavity, the upper ventilation vertical pipe connecting hole is located above the ventilation cavity, a gas channel is formed between the partition plate and the inner wall of the upper portion of the upper shell, and the drainage cavity is communicated with the ventilation cavity through the gas channel. And a water inlet hole is formed in the upper shell and is communicated with the drainage cavity. The pressure limit value curve of each layer of the drainage system tends to be stable under the maximum drainage flow, air pressure fluctuation in the drainage cavity and at the tee joint of the three-way pipe above the drainage cavity is effectively reduced, the drainage flow is large, the drainage effect is remarkable, the manufacturing cost is low, and practicability is high.
本发明公开了一种预埋式排水装置及双立管排水系统，包括上壳体和下壳体，上壳体与下壳体连接，在下壳体内设置有排水腔体和通气腔体，在排水腔体和通气腔体之间设置隔板，在排水腔体的下方开设有下排水立管连接孔，在通气腔体的下方开设有下通气立管连接孔；在上壳体上开设有上三通管连接孔和上通气立管连接孔，上三通管连接孔位于排水腔体上方，上通气立管连接孔位于通气腔体上方，隔板与上壳体上方内壁之间形成气体通道，排水腔体通过气体通道与通气腔体相连通；在上壳体上开设有进水孔，进水孔与排水腔体相通。本发明的排水系统在最大排水流量下的各层压力极限值曲线更趋于平稳，有效减小排水腔体内及上方三通管的三通处的气压波动，排水流量大，排水效果显著，造价成本低，实用性强。
