Remove silt in the collecting chamber for convenience, the bottom of described collecting chamber is provided with the sand setting section, is provided with above with respect to the sand setting section at the top of collecting chamber and gets husky mouthful.
Described is wide at the top and narrow at the bottom trapezoidal to the section of grid water discharging body in length and breadth, fills the coarse gravel of particle diameter 20～60mm, bird's-eye gravel and the sand material of particle diameter 2～20mm from top to bottom successively.
Described first filtration beds and second filtration beds are filled the coarse gravel of particle diameter 20～60mm, bird's-eye gravel and the sand material of particle diameter 2～20mm from top to bottom successively.
Beneficial effect of the present invention is:
1, the present invention can lead Channel Groundwater fast and be seeped in the channel, dewatering, and the stability of raising side slope prevents that seepage water from producing the jacking destruction and the problem of frost heave in winter to canal base plate and bank protection, improved the steadiness of channel and prolonged the life-span;
2, the present invention underground water is led fast be seeped in the channel in, can prevent the channel seepage, effectively improve the utilization factor of channel water;
3, the present invention adopts fabricated construction, is easy to batch production and produces easy construction in enormous quantities;
4, the present invention has utilized mechanics principle dexterously, has realized the unification of channel side slopes draining and antiseepage function, and is simple and reasonable, easy to maintenance, is easy to large tracts of land and promotes.

The specific embodiment
Below in conjunction with accompanying drawing, the mode by embodiment is elaborated to technical solution of the present invention, but protection scope of the present invention is not limited to described embodiment.
Shown in Fig. 1～5, a kind of channel seepage-guiding and non-return system comprises in length and breadth and oozes stop device 2 to grid water discharging body 1 with leading;
Described concrete anti-seepage panel 12 belows that are arranged on the channel bank protection in length and breadth to grid water discharging body 1; The described sandstone filtrate that in the grid of grid water discharging body 1, is filled with in length and breadth; Describedly ooze stop device 2 and be connected with described leading to the lower end of grid water discharging body 1 in length and breadth;
Described leading oozed in the groove that stop device 2 is arranged on the channel base plate, has concrete casing; The described top of oozing stop device 2 of leading flushes with at the bottom of the canal; The described internal construction of oozing stop device 2 of leading laterally is followed successively by first filtration beds, 3, the first geotechnological layer of cloth 4, the first porous concrete interlayer 5, the flexible sheet 6 of gauze wire cloth, collecting chamber 7, the second porous concrete interlayer, 9, the second geotechnological layer of cloth 10 and second filtration beds 11;
Described first filtration beds 3 side end faces directly are connected to the lower end of grid water discharging body 1 in length and breadth with described; The flexible sheet 6 of described gauze wire cloth will be separated by seepage channel and the collecting chamber 7 that first filtration beds, 3, the first geotechnological layer of cloth 4 and the first porous concrete interlayer 5 constitute, the top anchoring of the flexible sheet 6 of described gauze wire cloth is due to described collecting chamber 7, and the bottom can be to collecting chamber 7 direction bendings; The upper surface of described second filtration beds 11 directly contacts with water body at the bottom of the canal.
The bottom of described collecting chamber 7 is provided with sand setting section 13, is provided with above with respect to the sand setting section at the top of collecting chamber 7 and gets husky mouthful 8.
Described is wide at the top and narrow at the bottom trapezoidal to the section of grid water discharging body 1 in length and breadth, fills the coarse gravel of particle diameter 20～60mm, bird's-eye gravel and the sand material of particle diameter 2～20mm from top to bottom successively.
Described first filtration beds 3 and second filtration beds 11 are filled the coarse gravel of particle diameter 20～60mm, bird's-eye gravel and the sand material of particle diameter 2～20mm from top to bottom successively.
When underground water level is lower than the canal middle water level, act on and lead the channel hydraulic pressure that oozes on the stop device 2 greater than osmotic pressure, channel water enters collecting chamber 7 by second filtration beds 11 through the water hole of the second porous concrete interlayer 9, because the flexible sheet 6 right side hydraulic pressure of gauze wire cloth are greater than left side hydraulic pressure, the flexible sheet 6 of gauze wire cloth will touch collecting chamber 7 walls, will can not produce seepage.
When underground water level is higher than the canal middle water level, by after first filtration beds 3 and first geotechnological layer of cloth 4 filtrations, arriving the flexible sheets of gauze wire cloths 6 left sides to the seepage water that grid water discharging body 1 is collected in length and breadth by the first porous concrete carrier ring 5, owing to act on the flexible sheet 6 left side osmotic pressure of gauze wire cloth greater than right side channel hydraulic pressure, collecting chamber 7 walls will be left in the flexible sheet of gauze wire cloth 6 bottoms, seepage water enters collecting chamber 7, under the seepage pressure effect, seepage water will be by the second porous concrete interlayer 9, the second geotechnological layer of cloth 10 and second filtration beds, 11 reverse osmosis are gone in the channel, thereby have reduced groundwater table.
When silt in the collecting chamber 7 deposits, can open circle and get husky mouthful 8, get husky mouth with covering again after the silt cleaning.
