Abstract
The utility model discloses a kind of slub type digging foundation,Including column,Feature is that multiple expansion heads have been wholely set on column,Expanding head includes the truncated cone-shaped variable slope segment and cylindrical base seat of integrally connected,The grade of side slope of variable slope segment is 0.5 1.5 times,1.2 2 times of a diameter of column diameter of base seat,The height of base seat is the 0.1 0.3 of column diameter,The vertical range of the top of variable slope segment to the base seat bottom of upper one expansion head is 1.2 2 times of column diameter,The cylinder type hollow section for backfilled with earth is provided with column,Advantage is to increase horizontally and vertically bearing capacity,The base expanding and base expanding width of dredged foundation can be reduced,Reduce the risk of hand excavation,And make full use of the failure by shear ability of undisturbed soil,Effectively reduce buried depth,One expansion head of increase can be realized,Bearing capacity about 30% can be improved,Concreting side's amount is saved under conditions of foundation bearing capacity is not significantly reduced simultaneously.
Description
Technical field
It the utility model is related to a kind of slub type digging foundation.
Background technology
Digging foundation is to utilize mechanically or manually directly to dig in natural earth(Bore)Into required foundation ditch, by framework of steel reinforcement
The basis formed in foundation ditch is directly cast in concrete.A conventional dredged foundation typically only expansion head, and vertical at present
Column diameter is often relatively large in order to meet the needs of hand excavation, and in general tower load, column is too big, causes
The waste of material, while the minimum steel ratio requirement of column is also increased significantly;On the other hand, because big corner tower load adds
Greatly, the column of general dredged foundation, draw and dig depth and bellout diameter and all will be further increased, not only increase manually digging hole
Risk, and waste significantly basis quantities.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of slub type that can effectively improve bearing capacity and draws digging base
Plinth.
Technical scheme is used by the utility model solves above-mentioned technical problem:A kind of slub type digging foundation, including
Column, multiple expansion heads has been wholely set on described column, described expansion head includes the truncated cone-shaped variable slope segment and circle of integrally connected
Cylindrical base seat, the grade of side slope of described variable slope segment is 0.5-1.5 times, and a diameter of described column of described base seat is straight
1.2-2 times of footpath, the height of described base seat are the 0.1-0.3 of described column diameter, and the top of described variable slope segment is arrived
The vertical range of the base seat bottom of expansion head described in upper one is 1.2-2 times of described column diameter.
The cylinder type hollow section for backfilled with earth is provided with described column.
Compared with prior art, the utility model has the advantage of:The utility model makes public for the first time a kind of slub type and drawn
Basis is dug, single head that expands of conventional digging foundation is made into expand head more, expands size, soil property feelings that head quantity can be according to tower load
The difference of condition is appropriate to be selected;The bearing capacity of digging foundation be as caused by the interphase interaction of digging foundation base expanding and base expanding and soil,
Increase the bearing capacity of digging foundation using " ring " pattern, it is main to increase horizontally and vertically bearing capacity, it can reduce and draw digging formula
The base expanding and base expanding width on basis, reduces the risk of hand excavation, and makes full use of the failure by shear ability of undisturbed soil, effectively reduces and buries
It is deep, so as to effectively reduce square foundation amount;Further design column, variable slope segment and base seat three shape size and
Mutual distance, realize bearing capacity and maximize raising, so as to realize one expansion head of increase, you can to improve bearing capacity about
30%;Hollow digging foundation simultaneously, concreting side's amount is saved under conditions of foundation bearing capacity is not significantly reduced, in addition may be used
Spoir is backfilling into basis, so as to environmental protection.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model slub type digging foundation.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
Specific embodiment
A kind of slub type digging foundation, as shown in figure 1, including column 1, be wholely set on column 1 it is multiple expand first 2, expand
First 2 include the truncated cone-shaped variable slope segment 3 and cylindrical base seat 4 of integrally connected, and the grade of side slope of variable slope segment 3 is 0.5-1.5 times, base
1.2-2 times of the diameter of a diameter of column 1 of base 4, the height of base seat 4 are the 0.1-0.3 of the diameter of column 1, the top of variable slope segment 3
The vertical range of portion to upper one bottom of base seat 4 for expanding first 2 is 1.2-2 times of the diameter of column 1.
In this particular embodiment, the cylinder type hollow section 5 for backfilled with earth is provided with column 1.
Above-described embodiment is to further explanation of the present utility model, but the scope of protection of the utility model is with claim
Book is defined.
Claims (2)
1. a kind of slub type digging foundation, including column, it is characterised in that:Multiple expansion heads have been wholely set on described column,
