Fig. 1 and Fig. 2 shows a kind of french drain 1 for being used for waste landfill site leachate and collecting of embodiment of the utility model, blind
Ditch 1, which is arranged on, to be disposed with the refuse landfill of air guide gabion, and it includes：Interconnected main french drain and branch french drain；Main french drain
Formed with branch french drain by antipriming pipe 11, rubble packed layer 12 and non-woven geotextile integument 13；
As shown in Figure 3 and Figure 4, the body of antipriming pipe 11 is provided with through hole 14；In a kind of preferred embodiment, antipriming pipe
11 be high density polyethylene pipe.Through hole 14 antipriming pipe 11 the axially in-line setting of body, in 30 degree of body spaced radial uniformly
It is circumferentially disposed.Or through hole 14 is distributed in the body of antipriming pipe 11 with irregular mode.Rubble packed layer 12 surrounds antipriming pipe
11；In a kind of preferred embodiment, the particle diameter of rubble packed layer 12 is less than 50mm.Non-woven geotextile integument 13 is arranged on broken
The outside of stone packed layer 12, french drain 1 are the upper hexagonal structure being parallel to each other below.In a kind of preferred embodiment, nonwoven
Cloth is 260g/m2~320g/m2Non-woven fabrics.
The french drain convenient material drawing of the utility model above-described embodiment, it is only necessary in early-stage preparations antipriming pipe, rubble and nonwoven
Cloth can be constructed, quick construction, and leachate collecting effect is good.The effect of rubble packed layer is in filtering spam body Leachate site
Solid matter, prevent insoluble solid matter from being blocked into antipriming pipe.The effect of non-woven geotextile is that rubble packed layer is entered
Row sizing, prevent from being subjected to displacement antipriming pipe when the displacements such as slip occur for rubbish body, prevent antipriming pipe close to rubble packed layer
Side.
After the french drain 1 of above-described embodiment is arranged in into rubbish body 2, when running between it is longer when, due in rubbish body 2
Grain type material enters the blocking for easily causing antipriming pipe 11, because refuse landfill construction environment is poor, should reduce people as far as possible
Member carries out overhauling the spent time, it is therefore desirable to is accurately positioned the position for blocking and occurring.Above-described embodiment is used for
The french drain 1 that waste landfill site leachate is collected further improves, and the french drain 1 collected for waste landfill site leachate, it includes：
Interconnected main french drain and branch french drain, branch french drain connect with main french drain；Main french drain and branch french drain are filled out by antipriming pipe 11, rubble
Fill layer 12 and non-woven geotextile integument 13 is formed；The body of antipriming pipe 11 is provided with through hole 14；Rubble packed layer 12 surrounds more
Hole pipe 11；Non-woven geotextile integument 13 is arranged on the outside of rubble packed layer 12, and french drain 1 is upper six sides being parallel to each other below
Shape structure.Also include liquid level detection device 3, liquid level detection device 3 is arranged on the antipriming pipe 11 of main french drain 1 and/or branch french drain 1
It is interior.
As shown in figure 5, liquid level detection device 3 includes weight block 31, floating body 32, connecting rope 34, switch 33, control circuit
And voice guard；The switch 33 is arranged on floating body 32；One end of connecting rope 34 is connected with weight block 31, the other end with
