Abstract
The utility model discloses a jet grouting soil-cement-pile strengthened pile, which comprises a high-pressure jet grouting pile body and a pile core. The pile core is wrapped by the high-pressure jet grouting pile body, and the high-pressure jet grouting pile body comprises a bottom-fixed high-pressure jet grouting pile and at least one section of an upper-section high-pressure jet grouting pile body. The bottom-fixed high-pressure jet grouting pile comprises a bottom-expanding end arranged at the bottom and a high-pressure jet grouting pile section fixedly arranged with the bottom-expanding end, and the outer diameter of the bottom-expanding end is larger than that of the high-pressure jet grouting pile section. A gap is reserved between the upper-section high-pressure jet grouting pile body and the bottom-fixed high-pressure jet grouting pile, and the outer diameter of the upper-section high-pressure jet grouting pile body is the same as the outer diameter of the high-pressure jet grouting pile section. By means of the jet grouting soil-cement-pile strengthened pile which is arranged in sectioned mode according to the characteristics of foundation soil, characteristics of foundation is fully utilized, design requirements are met, simultaneously raw materials and construction time are saved, and manufacture cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of building foundation, relates to the combination pile body of lock pin stake in a kind of high-pressure rotary jet grouting pile specifically.
Background technology
At present, be used in the structure types of the various basic pile foundations of engineering such as construction work, bridge engineering, municipal engineering, hydraulic engineering stake of single structure type and the stake of combining structure type being arranged.The stake of combining structure type has compaction pile, Concrete Core Mixing Pile, 3M stake etc.There is following defective in the stake of these structures: the vibration that the compaction pile in the stake of combining structure type produces in manufacturing process, particularly disturb residents, and it rams the trial of expanding not only has limitation, and it can only improve the end load.Concrete Core Mixing Pile is because of being stirred, taken by force the influence of factors such as power and equipment limitation, and it stirs degree of depth, a stake footpath size all has limitation, the top weak soil is stirred the back improve lessly, and can only improve the part side friction, so bearing capacity is higher than not with price.Another important reasons is; Present compound pile; Its pile body or be that whole section pile body or bottom have that to expand the bottom, bottom be the unitary whole pile body with the top pile body from top to bottom, the side friction of this pile strength all can reach requirement, but does not make full use of the ground soil characteristics.Particularly the stake end soil of foundation soil is softer or inhomogeneous, has this soil layer of the better soil layer of multilayer character in the pile body scope.Because pile body is overall structure from top to bottom, its cost is higher, is unfavorable for raising the cost.
Summary of the invention
The purpose of the utility model just is to overcome above-mentioned deficiency a kind of high spray lock pin combination pile is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of high spray lock pin combination pile; Comprise the high-pressure rotary-spray pile body; Also comprise a core, high-pressure rotary-spray pile body parcel stake core, high-pressure rotary-spray pile body comprise that high-pressure rotary jet grouting pile of the solid end and at least one section epimere high-pressure rotary-spray pile body constitute; Gu end high-pressure rotary jet grouting pile comprises the expansion bottom of bottom and the high-pressure rotary jet grouting pile pile cutoff that is solidly installed with the expansion bottom; The external diameter that expands the bottom has certain distance greater than high-pressure rotary jet grouting pile pile cutoff external diameter between epimere high-pressure rotary-spray pile body and the high-pressure rotary jet grouting pile of the solid end, and the external diameter of epimere high-pressure rotary-spray pile body is identical with the external diameter of high-pressure rotary jet grouting pile pile cutoff.
Above-mentioned high spray lock pin combination pile, described stake core is prefabricated pile core or pours into the core stake.
Above-mentioned high spray lock pin combination pile, the cross section of described stake core is cylindrical or square.
Above-mentioned high spray lock pin combination pile, the stake of said perfusion core are immersed tube bored core stake or the stake of long auger perfusion core.
Above-mentioned high spray lock pin combination pile, the expansion bottom of high-pressure rotary jet grouting pile of the said solid end and high-pressure rotary jet grouting pile pile cutoff are the compound one that is.
Adopt technique scheme; The utility model has following advantage: according to the ground soil characteristics; When stake end soil is softer or inhomogeneous, with high-pressure rotary-spray technology high-pressure rotary jet grouting pile of the solid end is set, when having the better soil layer of multilayer character in the long scope of stake; In pan soil interlayer scope, the epimere pile body is set, lock pin stake in pile body.Segmentation is provided with compound pile according to the ground soil characteristics like this, makes full use of the characteristic of ground, when reaching designing requirement, has practiced thrift raw material and engineering time, has significantly reduced manufacturing cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
A kind of high spray lock pin combination pile as shown in Figure 1; Comprise the high-pressure rotary-spray pile body; Pitching pile core 4 in high-pressure rotary jet grouting pile, promptly the high-pressure rotary-spray pile body wraps up the stake core, and the high-pressure rotary-spray pile body comprises that high-pressure rotary jet grouting pile of the solid end and at least one section epimere high-pressure rotary-spray pile body 3 constitute; Gu end high-pressure rotary jet grouting pile comprises the expansion bottom 1 of bottom and the high-pressure rotary jet grouting pile pile cutoff that is solidly installed with expansion bottom 2; The external diameter that expands the bottom has certain distance greater than high-pressure rotary jet grouting pile pile cutoff external diameter between epimere high-pressure rotary-spray pile body and the high-pressure rotary jet grouting pile of the solid end, and the external diameter of epimere high-pressure rotary-spray pile body is identical with the external diameter of high-pressure rotary jet grouting pile pile cutoff.
The stake core of the utility model is prefabricated pile core or pours into the core stake that the stake of perfusion core is immersed tube bored core stake or the stake of long auger perfusion core.
The stake core cross section of the utility model can make cylindrical (like pile for prestressed pipe), can also make squarely (like concrete prefabricated side's stake).
The expansion bottom of the high-pressure rotary jet grouting pile of the solid end of the utility model and high-pressure rotary jet grouting pile pile cutoff can compoundly be one, also can separately construct.
Based on the ground soil characteristics, high-pressure rotary jet grouting pile system stake equipment is set, first high-pressure rotary-spray construction, this operation is processed pile body, with Pile feeder the stake core is inserted pile body then and forms high spray lock pin combination pile.
