Abstract
The invention provides a water-permeable foam concrete pile compound foundation, and belongs to the technical field of civil engineering. The compound foundation comprises pile bodies, pile caps and a mattress layer, wherein the pile caps are positioned at the top of the pile bodies; the mattress layer is positioned on the pile caps. The pile bodies are made of water-permeable foam concrete. Compared with the conventional material pile, according to the water-permeable foam concrete pile compound foundation, the self weight of the pile bodies is reduced, the water-permeable capability of the pile bodies is improved, and a longitudinal drainage passage is formed, so that sedimentation caused by self weight is reduced, solidification of foundation soil body is accelerated, the bearing capacity of the compound foundation is effectively improved, post-construction sedimentation of the foundation is controlled, and the construction period is shortened. Meanwhile, due to the properties of light weight, water permeability and the like, the compound foundation can achieve the same treating effect with relatively small size, so that the construction amount and material consumption can be reduced, the engineering cost can be effectively controlled, and relatively excellent economic benefits are obtained.
Description
Technical field
The present invention relates to technical field of civil engineering, refer to a kind of permeable foam concrete pile composite foundation especially, be applicable to the situation that soft foundation is reinforced.
Background technology
At present, in road project, the normal composite foundation form that adopts carries out consolidation process to soft foundation, and wherein pile foundation can transmit load to deep soil layer, is used widely.The normal stake adopted in current composite foundation, its pile shaft material is from great, and bad hydraulic permeability, be unfavorable for that the bearing capacity of foundation soil gives full play to, easily there is larger sedimentation in pile body self, and ground consolidation is slow.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of permeable foam concrete pile composite foundation, to overcome in current all kinds of composite foundation, and the stake deadweight deficiency of bad hydraulic permeability comparatively greatly.
This permeable foam concrete pile composite foundation comprises pile body, pile cover and mattress layer, and pile cover is arranged on pile body top, is provided with mattress layer above pile cover, and pile shaft material is permeable foam concrete, thus alleviates pile body deadweight, increases pile body water permeability.
The cross section of pile body is circular or square, and pile cover is variable cross-section truncated cone-shaped, prismatic table shape or prismatic cylindrical, prismatic, to bear upper load better.Pile cover material is the permeable foam concrete identical with pile body or the ordinary concrete meeting requirement for bearing capacity, the selection of the cementitious material of permeable foam concrete, admixture and Admixture and match ratio, determine bearing capacity of pile and permeable effect demand according to basement process, mattress layer is the loose seepy material of sandstone class.
Pile body and pile cover adopt prefabricated or on-the-spot pore-forming method for filling pile.
Pile body inside can arrange that pile body indulges in muscle or pile body stirrup one or both, whether the configuration quantity basis requirement for bearing capacity of configuration reinforcement and reinforcing bar and stressing conditions and determine in pile body.
The beneficial effect of technique scheme of the present invention is as follows:
Such scheme, compared with the composite foundation of existing all kinds of conventional material stake, effectively can reduce pile body deadweight, reduce because pile body is conducted oneself with dignity the sedimentation caused, pile body internal foam pore is interconnected simultaneously, formation longitudinal drainage passage increases water permeability, accelerates foundation soil consolidation, reduces settlement after construction and the remarkable reduction of erection time; Simultaneously due to lightweight, the characteristic such as permeable, adopt composite foundation of the present invention that the stake of reduced size can be adopted to reach identical treatment effect, compare conventional kind composite foundation, reduce construction volume and material usage, effective Control Engineering cost, obtains better economic benefit.

Detailed description of the invention
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The present invention is directed in existing all kinds of composite foundation, the stake deadweight problems such as bad hydraulic permeability comparatively greatly, provide a kind of permeable foam concrete pile composite foundation.
As shown in Figure 1, Figure 2 and Figure 3, this permeable foam concrete pile composite foundation is made up of pile body 1, pile cover 2 and mattress layer 3, and pile cover 2 is arranged on pile body 1 top, arranges mattress layer 3 above pile cover 2.
As shown in Figure 4, somewhere highway construction carries out consolidation process to soft foundation, adopts permeable foam concrete pile composite foundation provided by the invention.For making roadbed reach bearing capacity and settlement requirement, adopt drill-pouring piling method, form compound foundation.Wherein, pile body 1 adopts permeable foamed concrete material, the selection of its cementitious material, admixture and Admixture and match ratio, determines bearing capacity of pile and permeable effect demand according to basement process.Pile body 1 inside arranges pile body and indulges muscle 4 and pile body stirrup 5.Mattress layer 3 is the loose seepy material of sandstone class.
The cross section of the pile body 1 of foam concrete stake is square, and pile body 1 is through soft layer 8, and stake end arrives deep soil layer 9 and going down load.
For making stake, soil reaches co-operation state, and pile body 1 top is furnished with truncated cone-shaped pile cover 2, and is covered with mattress layer 3.Mattress layer 3 geotextiles 7 covers and bound edge.After the permeable foam concrete pile composite foundation of bottom has been constructed and met the requirement of bearing capacity and rigidity, banket on top and formed roadbed and road surface, top 6.
The present embodiment is only the concrete form of implementation of one of the present invention, and in the section form of its pile 1, the form of pile cover 2, pile body 1, configuration reinforcement and number of steel bars are determined according to requirement for bearing capacity and stressing conditions, and the present invention does not do concrete restriction.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
