Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1 and 2, the arrangement structure of the reverse filtering layer of the drainage hole of the waste rock blocking wall of the coal gangue pile comprises a water-resisting layer 1 arranged at the bottom of the waste rock pile and a waste rock blocking wall 2 arranged at the bottom of the waste rock pile in an enclosing manner, wherein a plurality of drainage holes 3 are formed in the waste rock blocking wall 2, a water permeable body 4 is arranged in each drainage hole 3, a reverse filtering monomer 5 is installed at the end part of each drainage hole 3, a supporting table 6 is arranged at the bottom of each reverse filtering monomer 5, the supporting table 6 is fixed on the waste rock blocking wall 2, a positioning bulge 7 is further arranged on each reverse filtering monomer 5, and correspondingly, a positioning clamping groove 8 is formed in each waste rock blocking wall 2, anti-skid spikes 15 are arranged on the periphery of each positioning bulge 7, and can improve the fixing reliability of each reverse filtering monomer 5; reverse filter unit 5 mainly comprises hemisphere inner frame 9, hemisphere outer frame 10 and aqueduct 11, hemisphere inner frame 9, hemisphere outer frame 10 sets up with one heart, and hemisphere outer frame 10 sets up the outside at hemisphere inner frame 9, install a plurality of aqueducts 11 between the hemisphere outer frame 10, hemisphere inner frame 9 and hemisphere outer frame 10 are hollow out construction, the edge of hemisphere inner frame 9 and hemisphere outer frame 10 is connected through annular plate 12, be filled with gravel 13 between hemisphere inner frame 9 and the hemisphere outer frame 10, the outside parcel of hemisphere inner frame 9 and hemisphere outer frame 10 has geotechnological cloth.
