The scoop is fixedly connected with inner tube.
Further, the front portion of the outer tube is provided with water hole.
Further, the outer tube and the circular in cross-section of inner tube.
A kind of method glided using described drainpipe processing side slope, is comprised the following steps：
（1）By the one end of drainpipe with scoop forward, drainpipe is headed into landslide；
（2）Extract the inner tube of drainpipe, the sand taken out in inner pipe end shovel out, underground water is discharged along drainpipe；
（3）Inner tube is put into outer tube, drainpipe is headed into landslide by continuation；
（4）Extract the inner tube of drainpipe, the sand taken out in inner pipe end scoop out, underground water is discharged along drainpipe；
（5）It is repeated in step（3）、（4）, wait that the phreatic line in coming down drops to 1-2m or so under landslide surface, excavate and slide
Slope soil, until drainpipe heads into landslide depths；
（6）After landslide soil to barricade bottom is excavated, build barricade by laying bricks or stones, build barricade bottom by laying bricks or stones and set tapping pipe, further arrange underground water, drop
Phreatic low；
（7）Treat that barricade solidifies, and the phreatic line in landslide is dropped under barricade top surface after 1-2m or so, utilizes barricade bottom
Tapping pipe draining lowering of watertable.
Further, step（1）Before, there is the neighbouring excavation sump at spring on bank protection top.
Compared with prior art, advantages of the present invention is as follows：Drainpipe can discharge aqueous sand and completely decomposed above side slope
The soil layer seepage in underground such as granite, can also discharge the concentration spring that the inconvenience above side slope is excluded, can using drainpipe of the present invention
The soil layer level of ground water such as aqueous sand and completely weathered granite effectively above reduction side slope, the mechanical property of enhancing side slope soil, place
Manage side slope to glide, it is ensured that stability of slope, be easy to bank protection Retaining wall, improve the construction quality of bank protection barricade, it is ensured that engineering construction
It is timely completed, using place, cost-effective, Support Construction project smooth implementation and the person of workmen effectively can be ensured
Safety.
