Fig. 2 is the sectional view in the A-A cross section in Fig. 1.
In above-mentioned Fig. 1 and Fig. 2, mattress layer 1, pile cover 2, plain concrete pile 3, inter-pile soil 4.
Detailed description of the invention
Core of the present utility model there is provided a kind of Pure-Concrete-Pile Composite Subgrade, in time and given full play to the bearing capacity of inter-pile soil of Pure-Concrete-Pile Composite Subgrade, reduces foundation deformation amount.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on embodiment of the present utility model, other embodiments all that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belong to the scope of the utility model protection.
Please refer to Fig. 1 and Fig. 2, the structural representation of a kind of Pure-Concrete-Pile Composite Subgrade that Fig. 1 provides for the utility model embodiment; Fig. 2 is the sectional view in the A-A cross section in Fig. 1.
The utility model embodiment provides a kind of Pure-Concrete-Pile Composite Subgrade, comprise plain concrete pile 3, inter-pile soil 4 and pile cover 2, plain concrete pile 3 is arranged in inter-pile soil 4, pile cover 2 is arranged on the top of plain concrete pile 3, and the sectional area of pile cover 2 is greater than the sectional area of plain concrete pile 3, a soffit part for pile cover 2 contacts with plain concrete pile 3, and a part contacts with the inter-pile soil 4 around plain concrete pile 3.
By arranging pile cover 2 at the top of plain concrete pile 3, the load part then acted on pile cover 2 is born by plain concrete pile 3, another part is born by the inter-pile soil 4 contacted with the soffit of pile cover 2, make inter-pile soil 4 and plain concrete pile 3 shared upper load, and most of load of Pure-Concrete-Pile Composite Subgrade of the prior art is born by plain concrete pile, and inter-pile soil only bears sub-fraction load, and increase foundation settlement because relatively lagging behind, compared to prior art, the shared effect of the oil and pile of the Pure-Concrete-Pile Composite Subgrade that the utility model provides is better, fully and in time play the stake of Pure-Concrete-Pile Composite Subgrade, earth cooperation carrying effect.
The utility model embodiment provides a kind of concrete pile cover 2, the cross section of pile cover 2 is circular cross-section, the diameter of section of pile cover 2 is greater than the diameter of section of plain concrete pile 3, more preferably, pile cover 2 and plain concrete pile 3 arranged concentric, adopt the pile cover 2 of circular cross-section to be convenient to calculate and easily construct, effective bearing area is larger.
Except adopting the pile cover 2 of circular cross-section, the cross section of pile cover 2 can also be polygonal cross-section, such as, and rectangle, pentagon, hexagon, octagon etc., as long as the section area of pile cover 2 is greater than the sectional area of plain concrete pile 3, the bottom surface section of pile cover 2 can be made to contact with inter-pile soil 4.
In order to ensure the bond strength of pile cover 2 and plain concrete pile 3, the top of the plain concrete pile 3 in the present embodiment extend in pile cover 2, and plain concrete pile 3 and pile cover 2 are integrated pouring structure, and namely plain concrete pile 3 is as a whole with pile cover 2.Certainly, plain concrete pile 3 and pile cover 2 can also be Split type structures, and pile cover 2 is placed on plain concrete pile 3 top.
Further optimization, the Pure-Concrete-Pile Composite Subgrade in the present embodiment also comprises the mattress layer 1 of side and the top being laid on pile cover 2, and mattress layer 1 can make upper load more uniformly act on inter-pile soil 4 and pile cover 2, improves stake, earth cooperation carrying effect.
As optimization, the mattress layer 1 in the present embodiment is broken stone cushion layer, and certainly, mattress layer 1 can also be made up of sandstone, slag, cobble, dirt etc., can also be plain concrete mattress layer.
Further, the thickness of the mattress layer 1 in the present embodiment is 20cm ~ 30cm.Mattress layer 1 is too thick, can not play the advantage of plain concrete pile 3, too thin, and bearing capacity too concentrates on plain concrete pile 3, therefore, adopts size of the present utility model that mattress layer 1 can be made to play and acts on preferably, oil and pile is carried jointly.
Pile spacing in the utility model and the degree of depth of stake are determined according to the soil layer situation in site operation place, are not specifically limited at this.
The construction method of the present embodiment to Pure-Concrete-Pile Composite Subgrade briefly introduces: facility are in place, by designing requirement pore-forming also clear hole; Then pour into plain concrete and vibration compacting, complete plain concrete pile 3; Reserved pile crown also installs pile cover template at pile crown position, and casting complete pile cover 2; Plain concrete pile 3 and pile cover 2 complete and lay broken stone cushion layer after reaching designing requirement, and thickness is 20 ~ 30cm, jointly forms Pure-Concrete-Pile Composite Subgrade.
In this manual, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
