Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, it is simple to be well understood to this utility model, but they do not constitute restriction to this utility model.
As shown in Figure 1, this utility model provides the road structure of a kind of bidirectional screw soil compaction grout pile net, the bidirectional screw soil compaction bored concrete pile 1 arranged including the many uniform intervals being embedded in ground 6, the reinforcement rim layer 3 being laid on ground 6 upper surface, the top of each bidirectional screw soil compaction bored concrete pile 1 is all coaxially arranged with pile cover 2, wherein said reinforcement rim layer 3 is arranged at pile cover 2 upper surface, described reinforcement rim layer 3 upper surface is equipped with monoblock type embankment 7, being equipped with toe wall 5 between embankment 7 and ground 6, the bottom of described toe wall 5 is embedded in ground 6.
Described reinforcement rim layer 3 includes bed course 31 and underlayer 32, is provided with mesh reinforcements 4 between upper bed course 31 and underlayer 32.Reinforcement rim layer 3 ensures pile cover 2 and bidirectional screw soil compaction bored concrete pile 1 uniform force so that it is can bear more load.Described mesh reinforcements 4 is GSZ or geotechnical grid or Woven geofabric or metal mesh sheet, and its tensile strength is not less than 100kN/m.Described mesh reinforcements 4 becomes planar, strengthens the intensity of reinforcement rim layer, thus improves the stability of road structure, makes more load be transferred to bidirectional screw soil compaction bored concrete pile 1.Described reinforcement rim layer 3 is graded broken stone or compacting dirt, and its thickness is 0.3～0.6m.When ground is collapsible loess, the material of reinforcement fardage should use compacting dirt.
Described bidirectional screw soil compaction bored concrete pile 1 is set up in parallel formation square or the pile body group of triangular arrangement side by side, and described pile body group is uniformly distributed along ground 6 length direction interval, and maximum construction stake length is up to 30m, and stake is long to be determined according to deformation and calculation of bearing capacity.Described bidirectional screw soil compaction bored concrete pile uses bidirectional screw soil compaction bored concrete pile, pile body can be xoncrete structure, it is a kind of by helix extruding-enlarging drill bit squeezed hole for inserting steel reinforcement cage mode after may be used without and forming the bidirectional screw soil compaction bored concrete pile described in reinforced concrete structure, guncreting, a kind of bidirectional screw soil compaction bored concrete pile eventually formed is synchronized during carrying brill.Under rig moment of torsion with vertical pressure effect, formation of pile uses machinery and the squeezed technique of pressure, the soil body in stake holes is expressed in the soil body around stake holes completely, and form cylindrical soil compaction type bidirectional screw soil compaction bored concrete pile completely.Bidirectional screw soil compaction bored pile piling technology has that telephone-moving and pile-forming speed be fast, work progress is not required to mud circulation, the duration is shorter, does not fetches earth, pollution-free, bearing capacity of single pile high.Described 1 footpath of bidirectional screw soil compaction bored concrete pile is 0.35～0.8m, and the spacing between adjacent bidirectional screw soil compaction bored concrete pile 1 is 3～6 times of stake footpaths.
The pile cover 2 that the top of be set forth in bidirectional helix extruding soil bored concrete pile 1 is arranged at correspondence is internal.For ensureing good mechanical characteristic, pile cover uses xoncrete structure, described in be positioned at bidirectional screw soil compaction bored concrete pile 1 length of pile cover 2 not less than 0.2m.Pile cover can be effectively increased the stress of bidirectional screw soil compaction bored concrete pile, reduces the stress of foundation soil.As in Figure 2-4, described pile cover is inverted round stage structure or cylindrical structure or rectangular structure, and the cross-sectional width that contacts with bidirectional screw soil compaction bored concrete pile end face of pile cover or diameter are not less than 2 times of stake footpaths.
During construction, first leveling place carries out the construction of bidirectional screw soil compaction bored concrete pile 1 again.Make bidirectional screw soil compaction bored concrete pile 1 through foundation soil body, make an end enter supporting course, and pile cover 2 is set on stake top.Then set the underlayer 32 of reinforcement rim layer on pile cover 2 top, apply mesh reinforcements 4 after completion, then apply the rim layer 31 of reinforcement rim layer.Position is being specified to apply toe wall the most again.Embankment above reinforcement cushion is set after completion, uses placement in layers, layered rolling construction.
The content that this specification is not described in detail belongs to prior art known to professional and technical personnel in the field.
