[0012] The technical scheme of the present application will be described in detail below with reference to the drawings, but the protection scope of the present application is not limited to the embodiments.

[0013] With reference to Figure 1 and Figure 2 , the present application is a double-layer filtering type drainage system using cement brick masonry, which comprises an open drainage channel and a buried drainage channel which are in communication with each other.

[0014] In the present application, the open drainage channel is designed; the drainage channel is excavated according to requirements, and the 45-degree inclined surface is reserved on both sides of the slope, then the bottom of the drainage channel is graded and tamped, and the cement hollow brick 1 is laid on the tamped bottom of the channel while the mortar is laid, so that the brick holes of the cement hollow brick are transversely connected with each other; after the cement hollow brick 1 is laid, the inclined surface of the soil on both sides of the slope is tamped, and then the concrete standard brick 2 is laid on the inclined surface while the mortar is laid, so that the top of the concrete standard brick is flush with the cement hollow brick 1; finally, grass seeds are sowed on the top of the soil on both sides of the channel.

[0015] The buried drainage channel is designed as follows: a vertical channel is excavated at the buried position of the drainage channel, and the bottom of the channel is graded and tamped, then the bottom layer cement hollow brick 3 is laid on the tamped bottom of the channel while the mortar is laid; after the bottom layer cement hollow brick 3 is laid, the top layer cement hollow brick 4 is directly laid; the bottom layer cement hollow brick 3 and the top layer cement hollow brick 4 are internally provided with the filtering screen 5, and finally the side of the cement brick is backfilled and tamped on both sides of the laid channel, and grass seeds are sowed. For the section which needs to cross the top, the reinforcing ribs can be arranged vertically on the channel, and the surface layer of concrete is poured.

[0016] In the double-layer filtering type drainage system, the open drainage groove can directly collect rainwater and sewage, the gap of the top layer of the cement hollow brick 1 is used to filter large pieces of dry garbage, so that the relatively clean rainwater and sewage permeate into the bottom hole, and then is collected into the drainage connection well chamber through the hole, and then is subjected to secondary precipitation and filtration of rainwater and sewage through the buffer of the drainage connection chamber and the filter screen 5 of the buried drainage passage, and finally the rainwater and sewage subjected to secondary filtration is discharged into the municipal pipe network through the buried drainage passage.

[0017] In addition to collecting rainwater and sewage filtered by the open drainage groove, the buried drainage passage can also be used as a blind ditch to filter and receive surface water in the soil, and then is discharged into the municipal pipe network.

[0018] As above, although the utility model has been shown and expressed with reference to specific preferred embodiments, it should not be interpreted as a limitation of the utility model itself. Various changes can be made to the form and details thereof without departing from the spirit and scope of the utility model defined in the appended claims.
