Preferably, one end that described anchor pole stretches in filler is provided with bending.Like this, by bending increasing action face, thus make body of wall and metope reliability higher.
Preferably, described inclusion enclave is spread the plastic knitting bagged sand folder gravel mixing grass-seed.
Preferably, described revers turn part comprises on earthwork grid second of first of coated described inclusion enclave and back-pressure.
Further preferred, described second is sewed together by pitman and geo-grid are hole-specifically interspersed.
Preferred further, the length of described revers turn part is not less than 2 meters.
Preferably, in body of wall, stretch into multiple uniform tapping pipe from described panel, described tapping pipe is crisscross arranged up and down, adjacent tapping pipe be spaced apart 0.9 ~ 1 meter.
Preferably, the height of described reinforced earth bulkhead is not more than 10 meters.
Preferably, the ratio of slope of described reinforced earth bulkhead is 1:0.25.
Preferably, described panel is interval with the parallel shrinkage joint of multiple tracks, parallel vertical face, described shrinkage joint; At the concrete substrate back side and be arrange needle-punched geotextiles behind shrinkage joint.
Preferably, the degree of depth of described filled ground is not less than 2 meters.
The beneficial effects of the utility model are: lay geo-grid and successively banket, and geo-grid is formed revers turn part, fill inclusion enclave, and be sewed together in revers turn part end and geo-grid in revers turn part; Synchronously can carry out the laying of metope reinforcing bar while successively banketing, and anchor pole is set, then carry out cast in situs metope; So, solve the problem of construction space and closing slope.Before banketing in earth's surface, carry out changing filling out filled ground with rubble, thus reinforced earth bulkhead is placed on good ground.Adopt above measure in sum, not only solve the problem of building up station roadbed reconstruction on filled ground, technology is simple, practical, convenient, economical, and safely, steadily.
