technical scheme of the present invention is achieved in that
the construction method of a kind of decomposition retaining wall of the present invention is, the method is 8 meters of punishment circles in decomposition retaining wall height H, and retaining wall height H is less than 8 meters one section and still adopts existing steel concrete cantilever construction; Retaining wall height H is equal to or greater than one section of employing reinforced bar net layered rolling structure of 8 meters; Steel concrete cantilever construction adopts and first constructs retaining wall, then the construction method of backfill; Reinforced bar net layered rolling structure adopts builds one deck building block, lays one deck grid, the construction method that pad one deck backfill compaction by rolling successively raises.
in preceding method, the construction sequence of described reinforced bar net layered rolling retaining wall is first in below ground construction reinforced bar concrete foundation, reinforced concrete foundation is built one deck building block, inside building block, lays one deck grid, grid pads one deck backfill compaction; Then repeat above-mentioned steps to build to design height always, last construct a steel concrete cap stone along most top layer block tops, and at building block external surface construction surface layer.
in preceding method, described grid width is not less than 2 meters, and the spacing between every layer of grid is not less than 350mm, and the degree of compaction of layered rolling backfill is greater than 93%.
according to of the present invention a kind of reinforced bar net layered rolling retaining wall structure that said method builds be, this structure comprises the reinforced concrete foundation located below ground level, reinforced concrete foundation is provided with the reinforced bar net layered rolling retaining wall body of wall be made up of building block, body of wall top is provided with steel concrete cap stone, and exterior surface of wall is provided with surface layer; Be equipped with the grid that layering is arranged inside body of wall, between grid, be provided with the backfill of layering compaction by rolling.
in aforementioned structure, described grid width W 1 is not less than 2 meters, and the spacing between every layer of grid is not less than 350mm.
owing to have employed technique scheme, the present invention compared with prior art, the present invention have employed different wall body structures according to the height difference of retaining wall, the present invention meets the requirement of bearing capacity of foundation soil by adopting reinforced bar net layered rolling structure at higher retaining wall, thus effectively eliminates potential safety hazard.The present invention had both met the requirement of bearing capacity of foundation soil, turn eliminated potential safety hazard, also saved the construction investment of operating surface simultaneously, shortened the construction period.Use through actual tests and prove, the present invention not only has the advantage that can effectively eliminate safe hidden trouble, but also has construction period short, less, rational in infrastructure, the stressed advantage such as clearly of investment.
