Description
Technical field
The utility model relates to a kind of composite foundation, is specifically related to a kind of broken stone pile and CFG stake combined composite foundation.
Background technology
In engineering practice, people have invented composite foundation, by ground, process, and improve the stress performance of natural ground, make it reach designing requirement.Composite foundation refers to that natural ground part soil body in ground processing procedure is enhanced, or replaced or reinforcement material is set in natural ground, under load action, and the effect of matrix and reinforcement shared load.In engineering reality, for high sensitivity silt, loosening sand Liquefaction Ground, solve the problems such as soil liquefaction, ground weakness simultaneously, traditional, single method for processing foundation does not often reach expected effect.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved has been to provide a kind of rational in infrastructure, easily construction, and supporting capacity is strong, the broken stone pile that foundation stability is high and CFG stake combined composite foundation.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: broken stone pile and CFG stake combined composite foundation, comprise: broken stone pile, CFG stake and sandstone cotton-padded mattress lining, the top of broken stone pile and CFG stake is provided with sandstone cotton-padded mattress lining, described broken stone pile spread configuration forms broken stone pile array, is provided with the CFG stake array consisting of CFG stake spread configuration between adjacent two broken stone pile.
Preferably, broken stone pile array, the alternate setting of CFG stake array, the thickness 30～50cm of sandstone mattress layer 3.
The beneficial effect that the utility model compared with prior art had is: the utility model is simple in structure, easy construction, adopt the ground that meets of broken stone pile and CFG stake formation, can effectively eliminate liquefaction, foundation capability significantly improves, can be used for polytype building, and foundation deformation dwindles by a small margin, greatly improved the safety of stability and the building of ground.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model broken stone pile and CFG stake combined composite foundation.
Fig. 2 is the arrangement schematic diagram of the stake of the utility model medium stone and CFG stake.
In figure: 1 is broken stone pile, 2 is CFG stake, and 3 is sandstone cotton-padded mattress lining.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.
As shown in Figure 1, broken stone pile and CFG stake combined composite foundation, comprise: broken stone pile 1, CFG stake 2 and sandstone cotton-padded mattress lining 3, the top of broken stone pile 1 and CFG stake 2 is provided with sandstone cotton-padded mattress lining 3, described broken stone pile 1 spread configuration forms broken stone pile array, between adjacent two broken stone pile 1, be provided with the CFG stake array being formed by CFG stake 2 spread configurations, described broken stone pile array, the alternate setting of CFG stake array, the thickness 30～50cm of sandstone mattress layer 3.
Adopt the composite foundation that broken stone pile and CFG stake form to process and there is practicality and good economy and social benefit widely highly sensitive soil, liquefaction soil layers ground.Be in particular in: adopt this structure, can significantly improve the supporting capacity of ground, eliminate soil liquefaction.Can adapt to polytype building; And can make foundation deformation significantly dwindle, the stability of ground and the safety of building also can improve greatly.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above; but the utility model is not limited to above-described embodiment; in the ken possessing those of ordinary skills; the various variations that can also make under the prerequisite that does not depart from the utility model aim, also should be considered as protection domain of the present utility model.
Claims (2)
