Description
Technical field
It the utility model is related to a kind of soft clay area building lot structure of cement mixing method combination Pulling-Resistant Anchor Rod.It is applicable
In building foundation treatment field.
Background technology
Coastal area is dispersed with shallow-layer littoral facies silting, muck soil more, and such weak soil has that thickness is big, compressibility
Height, shearing strength is low, low bearing capacity, and cohesive force is low to wait engineering characteristic.Such as Wenzhou northern territory it is widely distributed one layer of mud
Layer, the layer top general 2~8m of buried depth, the general 10~15m of thickness or so, for the fully exploitation underground space, intend in some stadium or
Single floor basement, no overlying burden are set under movable square, and foundation bearing capacity requires relatively low, but part basement bottom board position
In mud, bearing capacity can not meet design requirement and weak substratum be present；And basement roof is generally within underground water
Below plane, basement can produce larger buoyancy, and ground need to provide larger withdrawal resistance.
Such architectural tradition method for processing foundation is pile foundation, and mostly manually digging hole irrigates, while arranges by piling and resist
Pile pulling, but because this area's bearing course at pile end buried depth is big, general 30~50m, cause, and individual layer longer by piling and uplift pile
Lower room cost is relatively low, extremely uneconomical using long pile foundation, and has certain risk using manually digging hole.
The content of the invention
The technical problems to be solved in the utility model is：For above-mentioned problem, there is provided a kind of simple in construction, construction
The soft clay area building lot structure of convenient, safe and reliable, lower-cost cement mixing method combination Pulling-Resistant Anchor Rod.
Technical scheme is used by the utility model：A kind of soft clay area of cement mixing method combination Pulling-Resistant Anchor Rod is built
Build foundation structure, it is characterised in that：Construction has cement mixing method on soft soil foundation, if being fitted with the cement mixing method
The dry anchor pole being evenly arranged；
The parallel cement mixing method axis arrangement of the anchor pole, anchor pole insert Soil-cement by cement mixing method upper end
Stake, the upper end of the anchor pole is exposed outside cement mixing method；
Cement mixing method is corresponded on the soft soil foundation and is equipped with mattress layer, and reinforcement foundation is set on mattress layer,
The reinforcement foundation is connected with the bared end of the anchor pole.
The anchor pole lower end has the downward nose cone of cone.
At most there are two nose cones in the cement mixing method, on same cross section.
Spacing is more than 1m between cement mixing method cross section with the nose cone.
Its bending segment overlaps with the reinforcement foundation after the bared end bending of the anchor pole.
The bending segment length of the anchor pole is more than 250mm.
The beneficial effects of the utility model are：The utility model give full play to cement-soil stirring pile construction technical difficulty it is low,
The characteristics of cost is low, soft soil foundation applicability is good, overcomes the shortcomings of that heavy layer soft soil foundation can not set Pulling-Resistant Anchor Rod, there is the two
Machine combines, and can both provide enough bearing capacities, can provide enough withdrawal resistances again.The utility model is set in the lower end of anchor pole
Conical head is put, contributes to anchor pole to insert cement mixing method, and anchor pole is preferably combined as a whole with cement mixing method, is carried
For bigger anchor force.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment.
Fig. 2 is Fig. 1 A-A sectional views.
Embodiment
As shown in figure 1, the present embodiment is a kind of soft clay area building lot knot of cement mixing method combination Pulling-Resistant Anchor Rod
Structure, being constructed on soft soil foundation 6 has cement mixing method 1, and 7 anchor poles being evenly arranged are fitted with the cement mixing method 1
2, wherein an anchor pole 2 is located at the center of cement mixing method 1, arrange that remaining 6 are evenly arranged along the axis of cement mixing method 1
In centered on the axis of cement mixing method 1, radius on 40cm circle (see Fig. 2), and parallel to the axis of cement mixing method 1
Arrangement.
Anchor pole 2 inserts cement mixing method 1 by the upper end of cement mixing method 1 in the present embodiment, and the upper end of the anchor pole 2 is exposed
In 1 outer more than 1m of cement mixing method.The lower end of anchor pole 2 has the downward nose cone 22 of cone, in cement mixing method 1, together
At most there are two nose cones 22, and spacing is big between the cross section of cement mixing method 1 with nose cone 22 on one cross section
In 1m, to avoid 1 same cross section of cement mixing method from concentrating stress, avoid influenceing the intensity of cement mixing method 1.
Cement mixing method 1 is corresponded on this example soft soil foundation 6 and is equipped with mattress layer 3, and basis is set on mattress layer 3
Reinforcing bar 4.The section of exposing of the upper end of anchor pole 2 is bent to form the bending segment 21 that length is more than 250, and the anchor pole 2 in cement mixing method 1 is logical
The bending segment 21 crossed thereon is overlapped with reinforcement foundation 4, and anti-floating power is provided so as to based on.
The construction method of the present embodiment is as follows：
The first step, in ground construction cement mixing method 1.
Second step, before cement mixing method 1 does not solidify, to stir pile center as basic point, length of side 40cm is drawn on the ground
Regular hexagon, regular hexagon angle point and center difference static(al) press-in anchor pole 2, the pointed end of nose cone 22 of anchor pole 2.
3rd step, after cement mixing method 1 solidifies, soft soil foundation 6 is excavated to design ground basal plane, anchor pole 2 is cleaned out and exposes
Section.
4th step, mattress layer 3 is laid, and dispose reinforcement foundation 4.
5th step, anchor pole 2 is exposed into section bending, kink height can determine according to reinforcement foundation 4, need to ensure that curved segment length is big
Effectively overlapped in 250mm, and with reinforcement foundation 4.
6th step, base concrete 5 corresponding with reinforcement foundation 4 is poured, cement mixing method 1, anchor after concrete setting
Bar 2, basis form overall, common stress.
Certainly, described above is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
The those of ordinary skill in art field, in the scope of the utility model, change, addition or the replacement made, it should all belong to this reality
With new protection domain.
