It is trapezoidal pit to state and longitudinal cross-section is provided with coarse crushing rock layers, and the pit bottom surface and side wall are laid with geotextiles, described
Geotextiles are laid with coarse sands layer and rock layers in small, broken bits successively from lower to upper.
The structure base slab upper surface is provided with depression hole around the water-permeable pipe, and the water-permeable pipe is in the depression hole portion
Set up separately and be set to two sections, be connected with flange between two sections of the water-permeable pipe, rubber gasket is provided between the flange.
Depression hole top is provided with cover plate.
The water-permeable pipe and the cover plate are made of stainless steel.
One layer of base plate waterproofing is provided between the structure base slab and the bottom cushion, the base plate waterproofing is upward
Extension is coated on the permeable tube outer surface；The base plate waterproofing upper end passes through a steel plate inside the structure base slab
Seal ring is closely connected with the water-permeable pipe.Permeable tube outer surface described in being close to the steel plate water-stopping ring upper surface is additionally provided with rubber
Glue sealing rod.
The base plate waterproofing is Macromolecular self-adhesive membrane waterproof roll.
The beneficial effects of the utility model are：Loaded filter uses Multi-layer design, prevents that soil erosion ability is strong, and ensure
The foundation bearing capacity of bottom plate；Water proof structure is reasonable in design, the good water-proof effect of bottom plate；When the region of rich groundwater is gushed
During regimen condition, can sluice pressure-relief flow guide, ensure that scope of operation drying without ponding, creates conditions for construction of bottom plates.
