Detailed Description

The technical solution of the present invention will be further explained with reference to the embodiments shown in the drawings.

The basement retaining wall drainage pressure reduction system comprises a basement 2 separated by retaining walls 1 and a backfilling soil pit 3 dug above original soil, wherein a drainage pressure reduction unit is arranged in the backfilling soil pit 3, and is shown in figure 1.

The drainage pressure reduction unit comprises intensive water collecting pipes 4 (vertically arranged) arranged in a matrix form of rows and columns, a water filtering pipe cover for blocking silt is arranged at the pipe orifice of each water collecting pipe 4, the pipe bottoms of the water collecting pipes 4 are connected with each other through corresponding transverse pipes to form a communicating pipe array, one water collecting pipe 4 is selected from the communicating pipe array, a high water level sensor 7 is arranged at the pipe orifice of the water collecting pipe 4, a low water level sensor 8 is arranged at the pipe bottom of the water collecting pipe 4 and communicated with a water inlet of a horizontal section of a drainage pipe 5, a water outlet of the horizontal section of the drainage pipe 5 is communicated with a water inlet of a drainage pump 6, a water inlet of a vertical section of the drainage pipe 5 is communicated with a water outlet of the drainage pump 6, a water outlet of the vertical section of the drainage pipe 5 is upwards communicated with a backfilling soil pit 3, and the high water level sensor 7 and the low water level sensor 8 are respectively connected with a controller 9 arranged outside the backfilling soil pit 3 through corresponding sensing lines, the controller 9 is connected with the drainage pump 6 through a control line, the drainage pump 6 is connected with a power line leading out of the backfill soil pit 3, and a filter 10 is arranged on the horizontal section of the drainage pipe 5, as shown in fig. 1 and 2.
