Abstract
The invention provides a six-axis cement soil mixing pile. Six cement soil mixing piles are formed at one time and overlapped seamlessly, so that joints formed by original single-axis or two-axis cement soil mixing pile are reduced, the water-stopping effect and construction efficiency can be improved, the amount of labor used is reduced, and the construction period can be shortened by more than 2/3.
Description
Technical field
The present invention relates in the geotechnical engineering soft soil is reinforced and the cement mixing method of pattern foundation pit supporting structure, particularly raising weak soil intensity and pattern foundation pit supporting structure sealing keep off the six axle cement mixing methods in native field.
Background technology
When soft layer being reinforced with pattern foundation pit supporting structure, the method that usually adopts cement paste and the soil body to stir forms the Soil-cement pile body, thereby the intensity of soft foundation and sealing is greatly improved.The advantages such as traditional single shaft agitation pile and diaxon agitation pile are compared with three axle agitation piles in certain scope, have a water/binder ratio little, and displacement soil is few, and cement mixing content is little, and cost is low.But single shaft agitation pile or diaxon agitation pile are that the isodiametric cylinders handing-over of or two forms, as shown in Figure 1, form an overlapping the slot between every pile or per two piles, easily cause jag and seepage, this sealing to Soil-cement Wall has a significant impact.For single shaft or two axle cement-soil mixing pile machines, its power is less, the pile frame poor stability, and the stake machine moves manually to add rope traction, in construction, want frequent telephone-moving, take a large amount of working times, affect efficiency of construction, for above problem, in order to reduce telephone-moving number of times and overlapping the slot, reducing construction cost and raising work efficiency, single shaft agitation pile or two axle agitation piles, once the cement mixing method quantity of construction formation is little.For this reason, once forming long Soil-cement piling wall is a kind of new demand in ground stabilization and pattern foundation pit supporting structure field.
Summary of the invention
Technical problem to be solved by this invention is, overcome problems of the prior art, a kind of six axle cement mixing methods that provide ground stabilization or pattern foundation pit supporting structure to use, reduce the overlapping the slot of cement mixing method, improve the stagnant water effect of cement mixing method, improve efficiency of construction and reduction of erection time, reduce labour intensity and reducing construction cost.
Six axle cement mixing methods, cement mixing method is stirred by soil and cement paste and forms, one width of cloth Soil-cement Wall is comprised of the many vertical mutually cement mixing methods of overlap joint, several Soil-cement Walls overlap the longer Soil-cement Wall of formation mutually, it is characterized in that, every width of cloth Soil-cement Wall is comprised of the vertical cement mixing method of the six roots of sensation, and the same time of six roots of sensation cement mixing method forms, six roots of sensation cement mixing method is on same vertical plane, and adjacent pile body overlaps mutually; Adjacent Soil-cement Wall overlaps mutually.
Adjacent Soil-cement Wall overlaps mutually, more than the overlap joint scope 20mm.
Adjacent Soil-cement Wall overlaps mutually, and overlap joint is that a pile overlaps.
Adjacent pile body overlaps mutually, more than the overlap joint scope 20mm.
Six roots of sensation cement mixing method diameter is identical.
The water/binder ratio of cement mixing method 〉=0.3.
The cement mixed weight of Soil-cement 〉=3%.
More than the long 2m of stake of cement mixing method.
More than the diameter 300mm of cement mixing method.
Two adjacent Soil-cement Walls are parallel, mutually overlap or do not overlap.
Beneficial effect: six axle cement mixing methods of the present invention, the six roots of sensation cement mixing method of once constructing simultaneously, reduced the multiple tracks seam that former single shaft or two axle cement mixing methods form, improved efficiency of construction, reduced the amount of labour used, remedy the defectives such as three axle agitation piles displacement soil is many, water/binder ratio is large, cement mixing content is large, shortened the construction period more than 2/3rds.

The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Six axle cement mixing methods, cement mixing method is stirred by soil and cement paste and forms, one width of cloth stirs wall and is comprised of the many vertical mutually cement mixing methods of overlap joint, several Soil-cement Walls overlap the longer Soil-cement Wall of formation mutually, every width of cloth Soil-cement Wall is comprised of the vertical cement mixing method of the six roots of sensation, the same time of six roots of sensation cement mixing method forms, and six roots of sensation cement mixing method is on same vertical plane, and adjacent pile body overlaps mutually; Adjacent Soil-cement Wall overlaps mutually.
Elder generation's moulding six roots of sensation cement mixing method forms a secondary continuous Soil-cement Wall, and many secondary Soil-cement Walls form longer Soil-cement Wall.
Referring to Fig. 2, adjacent Soil-cement Wall overlaps mutually, more than the overlap joint scope 20mm.
Referring to Fig. 2 a, adjacent Soil-cement Wall overlaps mutually, and overlap joint is that a pile overlaps, and form of construction work is beaten for cover.
Again or, adjacent pile body overlaps mutually, more than the overlap joint scope 20mm.
Further, six roots of sensation cement mixing method diameter is identical, part is identical or different.Can carry larger soil pressure.
The water/binder ratio of cement mixing method 〉=0.3.The mass ratio of water and cement.Cement mixed weight in the cement mixing method 〉=3%.The mass ratio of cement quality and soil.
More than the long 2m of stake of cement mixing method.More than the diameter 300mm of cement mixing method.
Referring to Fig. 2 b and Fig. 2 c, two adjacent Soil-cement Walls are parallel, mutually overlap or do not overlap.
Fig. 2 d, many piles overlap mutually.
Referring to Fig. 3 and Fig. 4, adopt crawler type or walking pile frame and travel driving system, six roots of sensation drilling rod is arranged on the same vertical plane, arrange 3 shotcrete pipes, six roots of sensation drilling rod drives with six power set respectively, at leading truck of lower termination of drilling cramp, gives respectively six roots of sensation drilling rod guiding.
