Abstract
An earthwork cloth bag bulk material post filling pile relates to a foundation reinforced pile. The weaknesses existing in the prior art are that the pile-forming quality and permeable property are hardly to guarantee, and mud pollution exists. The filling pile comprises a pile body and a pile tip which is connected on the lower end of the pile body, wherein the pile body is a cylindrical body surrounded by earthwork cloth bags, and the inner portion of the earthwork cloth bag is provided with a bulk material holding cavity, a vertical grouting pipe is arranged in the bulk material holding cavity. The utility model well guarantees the pile-forming quality of the bulk material pile, and prevents mud in foundation from entering into a bulk material pile, thereby keeping the excellent and long permeable property of the bulk material pile, and preventing the slide movement of the pile material, and reducing ballooning damage, and the side friction of the pile can be evenly distributed through utilizing the characteristics of earthwork cloth bag of excellent stretch property, dispersive stress and fast delivery, thereby avoiding the mud contaminating the bulk material pile and the surrounding environment. The construction cost is low, and the pile strength can be further increased through adopting the grouting way.
Description
[technical field]
The utility model relates to a kind of foundation reinfored stake, particularly a kind of geotechnological cloth bag discrete material post grouting pile.
[background technology]
Discrete material is used among the Soft Soils Consolidation in A of roadbed, dykes and dams because of among it has higher intensity, water permeability, higher characteristics such as anti-liquefaction performance are progressively being applied preferably more.
Existing discrete material pile general employing earlier when construction punched in ground with machinery, then discrete material directly inserted the mode that forms the cylindricality pile body in the hole and come ground is reinforced.But discrete material has the mechanical characteristic that vertical load is carried out horizontal transfer, and its pile body bearing capacity depends on the lateral confinement power that pile peripheral earth can provide, if foundation soil body provides lateral confinement power less, pile body when load-bearing easily to around blow-up takes place and destroy.And the tiny soil body particle around the stake easily enters in the discrete material pile, causes the water permeability of pile body to descend.In addition, also there are problems such as mud contamination in present traditional discrete material pile work method.
[utility model content]
In order to overcome the above-mentioned defective that exists in the prior art, the utility model provides a kind of geotechnological cloth bag discrete material post grouting pile, limit with the periphery of geotechnological cloth bag discrete material pile, with the purpose that reaches assurance pile body stability and water permeability, reduces cost, and add Grouting Pipe, by the mode of pile grouting behind shaft or drift lining,, form rigid pile with further raising strength of the mixing pile.
For this reason, the utility model is by the following technical solutions: geotechnological cloth bag discrete material post grouting pile, it is characterized in that: it comprises pile body and is connected in the stake point of pile body lower end, the cylinder of pile body for surrounding by the geotextiles bag, have the discrete material container cavity in the geotextiles bag, be provided with vertical Grouting Pipe in the discrete material container cavity.Geotextiles has good three-dimensional permeable characteristic, and the effect that can play slow polywater and water is drained rapidly along geotextiles is played reverse filter effect to surrounding soil fine earth particle simultaneously, prevents that fine grained from entering in the pile body, guarantees permeable effect.Geotextiles separates discrete material in the pile body and surrounding soil, forms stable interface.After a point is set, then geotechnological cloth bag is put into immersed tube, directly squeeze into ground then, extract immersed tube to certain depth, fill discrete material again and can form pile body in bag, construction costs is lower.This programme can utilize discrete material pile to serve as the effect of water discharging body earlier when implementing, discharge the pore water in the ground, when needs are further strengthened strength of the mixing pile, pour into slurries by the space of Grouting Pipe between discrete material, just can make the material stake form a solid hard pile body.The discrete material container cavity of this programme can be inserted loose materials such as rubble, gravel, waste residue, flyash, sand and mixture thereof.When using present technique to ensure the discrete material pile pile quality, effectively avoided mud to the pollution of discrete material pile with to the pollution of surrounding environment.
As further improving and replenishing to technique scheme, the utility model is taked following technical measures: be with some locating racks on the described Grouting Pipe, the outer rim of locating rack is supported in geotextiles bag inboard, both made Grouting Pipe remain on discrete material container cavity central authorities, slurries can be uniformly distributed in the pile body when guaranteeing slip casting, play that bag is strutted, keep the effect of desirable cylindricality.
Described stake point links to each other with the geotextiles bag by connector.Connector can be members such as hook, locating ring, and the stake point is closely linked to each other with the geotextiles bag.
The sharp reinforced concrete pile point of described stake, it comprises the cylindrical portion and the conus portion of being located at the cylindrical portion downside of upside, and conus portion is convenient to pile body is squeezed in the ground, and cylindrical portion is corresponding with geotextiles bag shape, guarantees that bag can launch in ground fully.
Described stake point is a steel plate, and the intensity height is made simple.
Described geotextiles bag is non-woven geotextile or spins the geotextiles bag or the composite earthwork cloth bag.Can select as required.
Beneficial effect: the utility model is by being provided with spinning the geotextiles bag, being convenient to directly pile body be squeezed into stake point and Grouting Pipe in the ground of restriction discrete material, ensure the pile quality of discrete material pile, prevent that the earth in the ground from entering discrete material pile, and good, the lasting water permeability of maintenance discrete material pile, stop the shifted laterally of material of body of a pile, reducing bulging destroys, utilize geotextiles good extending performance, stress dispersion and transmit fast characteristics, can make uniformization of side-friction force, avoid mud to the pollution of discrete material pile with to the pollution of surrounding environment.Construction cost is cheap, and can adopt grouting mode further to improve strength of the mixing pile.

[specific embodiment]
Geotechnological cloth bag discrete material post grouting pile as shown in Figure 1, 2, have discrete material container cavity 1, geotextiles bag 2 lower ends in the cylindricality geotextiles bag 2 and be connected with stake point 3 by connector, be provided with Grouting Pipe 4 in the discrete material container cavity, Grouting Pipe 4 is with some locating racks 5, and the outer rim of locating rack 5 is supported in geotextiles bag inboard.The stake point comprises the cylindrical portion of upside and is located at the conus portion of cylindrical portion downside.The geotextiles bag can or spin geotextiles and make with non-woven geotextile.
Its work progress is as shown in Figure 3:
1) geotechnological cloth bag 2 is connected with precast pile tip 3.
2) under the traction of falling rope 6, geotechnological cloth bag 2 is hung in the immersed tube 7.
