in preceding method, described ramp punishes into two sections height 8 meters; Height is lower than when 8 meters being ramp height comparatively end section, and height is higher than when 8 meters being ramp height upper sector.
in preceding method, reinforced concrete foundation is provided with bottom the retaining wall of described ramp height upper sector, tension rib is embedded with inside retaining wall, between the retaining wall of both sides, backfill construction is carried out in layering, one deck reinforcing bar drawknot net is laid between every layer, reinforcing bar drawknot net welds with the tension rib be embedded in inside retaining wall, is routed to concordant with the retaining wall of both sides always; Then one reinforced concrete circle beam is built at retaining wall top.
in preceding method, when backfill construction is carried out in described layering, every layer of backfill should roll compacting, and compacting degree is more than or equal to 93%; The spacing of reinforcing bar drawknot net is not more than 0.4 meter.
according to the decomposition ramp used soil-baffling structure that preceding method is formed, described ramp with height 8 meters of for boundary, be provided with multistory reinforced drawknot net between the retaining wall of ramp height higher than 8 meters of section both sides, reinforcing bar drawknot net both sides are welded with the tension rib be embedded in retaining wall; Backfill is provided with between multistory reinforced drawknot net.
in aforementioned soil-baffling structure, the interlamellar spacing of described reinforcing bar drawknot net is 0.4 meter.
in aforementioned soil-baffling structure, be provided with reinforced concrete foundation bottom described retaining wall, reinforced concrete foundation is the strip of cross section 1000 × 400mm.
in aforementioned soil-baffling structure, described retaining wall top is provided with C25 reinforced concrete circle beam.
compared with prior art, the present invention makes ramp height into reinforced soil retaining wall higher than the steel concrete cantilever retaining wall of 8 meters of sections, not only can meet the requirement of bearing capacity of foundation soil, and can also investment reduction and reduction of erection time.When carrying out backfill construction, lay one deck backfill, paving one deck reinforcing bar drawknot net, lay one deck reinforcing bar drawknot net every 0.4, reinforcing bar drawknot net welds with the tension rib in retaining wall, can reduction of erection time greatly.The present invention substantially increases the bearing capacity of retaining wall, ensure that ramp height is higher than the stability of 8 meters of sections and security reliability.Bearing capacity of foundation soil of the present invention can meet the requirement in electrolytic aluminium decomposition ramp completely, has saved investment, has shortened the construction period; Structure stress is clear and definite, reasonable, avoids potential safety hazard, ensures the safety of structure.
