Description
Technical field
The present invention relates to a kind of retaining wall and job practices thereof, relate in particular to a kind of retaining wall and job practices thereof that is provided with lattice guest structure.
Background technology
Existing building retaining structure comprises flat bed reinforced structure, reinforced gabion structure etc.
Traditional flat bed reinforced structure is by beam, baffle plate, muscle band and the common soil-baffling structure of forming that bankets, and its loading characteristic is that earth lateral pressure passes to beam through baffle plate, passes to the muscle band by beam again, keeps balance by the uplift resistance of muscle band again.There is following defective in this structure: at first, because the existence of beam causes the retaining wall face attractive in appearance inadequately; Secondly, when the flat bed reinforced structure is higher, prefabricated units is installed is used crane gear, otherwise need the cast in situs member.
Traditional reinforced gabion structure is unfavorable for site operation, in addition because the structure size is bigger; Because monolithic lattice guest unit is adopted in traditional reinforced gabion structure end, perhaps adds a baffle plate therein and separates, material is wasteful; Construction requirement is high; And the effect that monolithic lattice guest also will serve as the face wall net in the unit is consumed greatlyyer, is unfavorable for later maintenance.
Summary of the invention
The technical problem that the present invention will solve is the deficiency that overcomes prior art; A kind of surface greening is provided, construction is convenient, cost is low, wide accommodation, pillar reinforced gabion retaining wall that mechanical property is good; In addition, the present invention also provides the job practices of the pillar reinforced gabion retaining wall that a kind of technology is simple, easy to operate, cost of labor is little.
For solving the problems of the technologies described above; The technical scheme that the present invention proposes is the pillar reinforced gabion retaining wall; Said retaining wall comprises the above body of wall that divides of one side; Body of wall mainly was made up of a plurality of reinforced gabion unit that superpose successively from the bottom to top in said minute, and said reinforced gabion unit comprises lattice guest assembly and the hangover formula muscle band net that is connected with said lattice guest assembly, and the online side compacting of said muscle band has backfill; Said lattice guest assembly comprises at least two spaced gabion net cages; Said isolated gabion net cage is interconnected in aggregates by the vertical face fence net that is positioned at its side, be filled with building stones in the said gabion net cage, and the gabion net cage mutual superposition that is arranged in two neighbouring reinforced gabion unit forms lattice guest post spaced apart.
In the technique scheme, preferred, body of wall was more than the two sides in said minute, and the two sides is above divides the body of wall along continuous straight runs mutual adjacent layout.
In the technique scheme, preferred, said gabion net cage is preferably prismatic (more preferably adopting shapes such as cuboid, square), and said lattice guest post is the lattice guest prism that prismatic gabion net cage stack back forms.Said face wall net connects into the prism reinforced gabion retaining wall with a plurality of lattice guest prisms spaced apart.
In the technique scheme; Preferably; Face wall net in the said reinforced gabion unit and muscle band net are to be converted into L shaped obtaining by the monolithic wire lath, and said face wall net is the part that vertical direction has extended the face wall effect, and said muscle band net has then extended the part of muscle band effect for horizontal direction.
In the technique scheme, preferred, said wire lath is a twisted hexagon net.
In the technique scheme, preferred, said face wall net and the contacted one side of said backfill are laid one deck loaded filter at least.
In the technique scheme, preferred, said loaded filter comprises geotextiles and coir fibre mattress.
As a total technical conceive, the present invention also provides a kind of job practices of pillar reinforced gabion retaining wall, may further comprise the steps:
(1) material is prepared: prepare a plurality of gabion net cages, face wall net, muscle band net, backfill, geotextiles and coir fibre mattress;
(2) reinforced gabion unit formation: at least two gabion net cages are spread at interval put; Said gabion net cage is interconnected by the vertical face fence net that is positioned at the side and constitutes lattice guest assembly; The dowel band net in the bottom surface of said lattice guest assembly; Said muscle band net extends along the horizontal direction away from lattice guest assembly, in the gabion net cage of said lattice guest assembly both sides, loads building stones respectively then, does not connect lattice guest assembly one side along vertically laying one deck geotextiles and coir fibre mattress at least to the face wall net; Put backfill and compaction in layers to shop, the online side of muscle band, obtain the reinforced gabion unit;
(3) divide the body of wall moulding: the reinforced gabion unit that obtains after accomplishing with step (2) is the basis, vertically repeats to build and builds said reinforced gabion unit, until the design height that arrives the pillar reinforced gabion retaining wall;
(4) pillar reinforced gabion retaining wall global formation: repeating step (2)～step (3); Accomplish the construction that multiaspect is divided body of wall; And make the adjacent successively layout of each minute body of wall along continuous straight runs, until the design length that arrives the pillar reinforced gabion retaining wall, accomplish construction.
Compared with prior art, the invention has the advantages that:
1. the advantage of pillar reinforced gabion retaining wall of the present invention is: compare traditional structure, the gabion net cage of pillar reinforced gabion retaining wall of the present invention and the face wall net outside can be afforested, and belong to ecologic structure; Can form view, meet the requirement of current harmonious society, pillar reinforced gabion retaining wall of the present invention only need be made simple ground and handle or do not do the ground processing; Applicable to the lower unfavorable foundation area of bearing capacity, the present invention saves labor and materials, and cost is lower; And have the characteristic of free drainage, need not to be provided with drain hole on the face wall, in addition; Pillar reinforced gabion retaining wall of the present invention belongs to flexible retaining structure, can adapt to the foundation settlement in the certain limit;
2. the advantage of pillar reinforced gabion retaining wall job practices of the present invention is: at first; Because main member of the present invention is precast assembly, even also can construct, in addition at narrow engineering site or strict place of limiting noise, vibrations; The job practices construction technology of pillar reinforced gabion retaining wall of the present invention is simple; Only need the simple operation that repeats, needn't in maintenance, drop into big man power and material, all construction operation can be accomplished in a side of banketing.
