Abstract

The invention relates to the technical field of piping treatment, in in particular to an inverted filtration trunk system. The inverted filtration trunk system comprises a pipe body, a box body and a filling layer, wherein an opening in the bottom side of the pipe body is used for being in communication with a piping channel, the box body extends into the pipe body from an opening in the top side of the pipe body, the box body is of a hollow structure, a first water stop plate used for preventing piping water from flowing upwards is annularly arranged on the outer side of the box body, a plurality of through holes for inflow of the piping water are formed in the side wall and / or the bottom wall of the box body, the through holes are located below the first water stop plate and located in the pipe body, the top of the box body is further provided with a drainage pipe which is used for leading the piping water out of the box body to the outside, the filling layer comprises a filtering layer and a sealing layer which are arranged from bottom to top, the filtering layer surrounds all the through holes, at least one part of the sealing layer is located in the pipe body, and the first water stop plate is embedded in the sealing layer. The inverted filtration trunk system aims to achieve the effects of being capable of dredging piping water and prevent silt loss. The invention further provides a piping treatment method.

Description

technical field [0001] The invention relates to the technical field of piping treatment, in particular to an anti-filter casing system and a piping treatment method. Background technique [0002] Piping is a phenomenon in which fine particles of the soil form pores along the skeleton particles under the action of seepage, and the increase of the flow velocity of water in the pores of the soil causes the fine particles of the soil to be washed away. [0003] The foundation pit is an earth pit excavated at the foundation design position according to the base level and foundation plane size. Foundation pit construction is an important part in civil engineering construction, and the stability of foundation pit affects the progress of the entire construction project. However, if piping occurs, the piping will take away a large amount of sediment and may cause the foundation pit to collapse. Therefore, it is very necessary to deal with the piping in time during the foundation pi...
