Abstract
A kind of method preventing discrete material pile bulging destruction in composite foundation, on the outer top of the pile body of discrete material pile, one circle first foundation wall is set, the second foundation wall is connected with between the first foundation wall that adjacent studs is external, first foundation wall, the second foundation wall from pile body top to the degree of depth for leaving pile body top 2D, D is pile body diameter, the present invention makes full use of the mutual constraint between adjacent pile body, and economy is practical again.
Description
Technical field
The invention belongs to composite foundation discrete material pile technical field, be specifically related to a kind of method preventing discrete material pile bulging destruction in composite foundation.
Background technology
Discrete material pile (broken stone pile, sand pile, sand-gravel pile etc.).For broken stone pile, it is the good method of consolidation process pine, soft foundation, and the composite foundation formed by broken stone pile method can improve bearing capacity of foundation soil and reduce sedimentation.Broken stone pile pile body has good water permeability, is conducive to excess pore pressure dissipation, has good economic benefit and social benefit.The depth that to take broken stone pile as the mode of failure overwhelming majority of the discrete material pile body of representative be, and top occurs that bulging destroys (experimentally result, being easy to occur place that bulging destroys most is that to push up down 2/3D(D from stake be stake footpath)).This is because the material of on the one hand composition pile body is noncohesive, has discrete material power diffusion effect and the own intensity degree of depth of pile body and increasing, and increases produce the possibility that plasticity bloats and diminish with the degree of depth; The resistance bloated due to inter-pile soil opposing pile body on the other hand also increases with the degree of depth.At present, the method for employing has geosynthetics to add hoop method, tubular type grill reinforce method etc. at stake top, but the material of these methods itself can deformed in tension, can produce certain lateral displacement adding hoop section pile body; Also have employing prestressed reinforced concrete to wrap and add the method at hoop pile body top, but this method expense material is taken a lot of work.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of not only economy but also practical method---a kind of method preventing discrete material pile bulging destruction in composite foundation.
In order to achieve the above object, the technical scheme that the present invention takes is:
Prevent the method that in composite foundation, discrete material pile bulging is destroyed, comprise the following steps: one circle first foundation wall 2 is set on the outer top of pile body 1 of discrete material pile, between the first foundation wall 2 outside adjacent pile body 1, be connected with the second foundation wall 3.
The first described foundation wall 2, second foundation wall 3 is from pile body 1 top to the degree of depth for leaving pile body 1 top 2D, and D is pile body 1 diameter.
The thickness of the first described foundation wall 2, second foundation wall 3 is 120-370mm.
The first described foundation wall 2, second foundation wall 3 all adopts solid plain brick.
If pile layout lays out pile with square or rectangle, then the second foundation wall 3 is set at the four direction of pile body 1.
If pile layout lays out pile with triangle, then the second foundation wall 3 is set at the six direction of pile body 1.
Beneficial effect of the present invention: make full use of the mutual constraint between adjacent pile body 1, gather materials on the spot, easy construction, economy are practical again.
Accompanying drawing explanation
Fig. 1 is the first foundation wall 2, second foundation wall 3 horizontal cross of single pile body 1.
Fig. 2 is the first foundation wall 2, second foundation wall 3 vertical sectional view of single pile body 1.
Fig. 3 arranges the horizontal cross that the first foundation wall 2 and four direction arrange the second foundation wall 3 when laying out pile with quadrangle at pile body 1 place.
Fig. 4 arranges the horizontal cross that the first foundation wall 2 and six direction arrange the second foundation wall 3 when laying out pile with triangle at pile body 1 place.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
A kind of method preventing discrete material pile bulging destruction in composite foundation, comprise the following steps: on the outer top of pile body 1 of discrete material pile, one circle first foundation wall 2 is set, the second foundation wall 3 is connected with, as depicted in figs. 1 and 2 between the first foundation wall 2 outside adjacent pile body 1.
The first described foundation wall 2, second foundation wall 3 is from pile body 1 top to the degree of depth for leaving pile body 1 top 2D, and D is pile body 1 diameter.
The thickness of the first described foundation wall 2, second foundation wall 3 is 120-370mm.
The first described foundation wall 2, second foundation wall 3 all adopts solid plain brick.
As shown in Figure 3, if pile layout lays out pile with square or rectangle, then the second foundation wall 3 is set at the four direction of pile body 1.
As shown in Figure 4, if pile layout lays out pile with triangle, then the second foundation wall 3 is set at the six direction of pile body 1.
The above, it is only the preferred embodiment preventing discrete material pile bulging destruction methods in composite foundation of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when the method preventing composite foundation medium stone stake bulging from destroying and technology contents that can utilize above-mentioned announcement make the Equivalent embodiments changing or be modified to equivalent variations a bit, in every case be the content not departing from technical solution of the present invention, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, still belong in the scope of technical solution of the present invention.
