Description
Technical field
The utility model relates to a kind of foundation structures, more specifically, it relates to which a kind of cement fly ash gravel pile is compound
Ground capital construction base reinforced structure.
Background technique
The mode for mostly using high pressure water soil digging in building inclination rectification at present is exactly outer on the lesser basis of building settlement
The soil layer drilling of side is placed into pvc pipe or steel pipe, then uses high pressure pump priming, and high pressure water is overflowed from nose end, and will be neighbouring
Soil layer becomes mud and is extruded ground, is controlled by the mud amount and mud balance of outflow and takes native amount, to reach to building
The purpose of object rectification righting.Although this method is simple, rectification speed is slow, it is not easy to control expected correction amount, and have
Biggish construction risk.And over time, building basis deep foundation base will continue gradually to produce after being weakened by water
Change shape, existing building i.e. can this run-off the straight again, also just need again to building carry out rectification righting, increase work
Amount, also to the inconvenience of the work and life band of nearby residents, therefore this form of construction work does not have the safety used.
In engineering practice, people have invented composite foundation, by basement process, improve the stress performance of subsoil,
Reach design requirement.Composite foundation refers to that subsoil part soil body during basement process is enhanced, or is set to
Reinforcement material is changed or is arranged in subsoil, under load action, the effect of matrix and reinforcement shared load.In work
Journey in practice, for high sensitivity silt, loosening sand Liquefaction Ground, solve soil liquefaction, ground weakness etc. simultaneously and ask
Expected effect is often not achieved in topic, traditional, single method for processing foundation.Cement fly ash gravel pile (i.e. CFG) is
Important component part in a kind of common ground capital construction base reinforcement composite construction.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of cement fly ash gravel pile to answer
Close ground capital construction base reinforced structure.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of cement fly ash gravel pile is compoundly
Capital construction base reinforced structure, including CFG, broken stone pile and basal layer, the basal layer be sandstone packing layer, described CFG with it is broken
Stone mar composition support array, the sandstone packing layer are laid on above support array, CFG and broken stone pile in the support array
To arrange interval dislocation array arrangement, the central part of the broken stone pile is equipped with the seamless steel pipe concentric with broken stone pile, described CFG
Multiple tracks drain tank is offered on side wall.
Preferably, the side wall of the seamless steel pipe is equipped with the reinforcing rib of multiple tracks and seamless steel pipe axis parallel,
The surface of the reinforcing rib is equipped with spiral lamination.
Preferably, the drain tank is metal drain tank, the downward V in multiple tips is equipped in the metal drain tank
Type guide groove.
The utility model compare compared with the prior art have the advantage that it is easy for construction, seamless steel pipe cooperate broken stone pile and
The bearing capacity of CFG acquisitions is strong, and CFG stake is equipped with drain tank, can greatly improve the CFG Compound Foundation
The drainability of base reinforced structure is built, therefore can be widely applied to the building lot in house.
Detailed description of the invention
Fig. 1 is the structural representation that the utility model CFG Compound Foundation builds base reinforced structure embodiment
Figure.
In figure: 1, broken stone pile；2, CFG；3, sandstone packing layer；4, seamless steel pipe；5, drain tank.
Specific embodiment
Base reinforced structure embodiment is built to the utility model CFG Compound Foundation with reference to the accompanying drawing to do
It further illustrates.
A kind of CFG Compound Foundation builds base reinforced structure, including CFG stake 2, broken stone pile 1 and basal layer,
Basal layer is sandstone packing layer 3, and CFG stake 2 and the composition support array of broken stone pile 1, sandstone packing layer 3 are laid on support array
Square, CFG stake 2 and broken stone pile 1 are in support array to arrange interval dislocation array arrangement, and the central part of broken stone pile 1 is equipped with and broken stone pile 1
Concentric seamless steel pipe 4 offers multiple tracks drain tank 5 on the side wall of CFG stake 2.Easy for construction, seamless steel pipe 4 cooperates broken stone pile 1
The bearing capacity obtained with CFG stake 2 is strong, and CFG stake 2 and the composition support array of broken stone pile 1 support CFG stake 2 and broken stone pile 1 in array
To arrange interval dislocation array arrangement, CFG stake 2 is equipped with drain tank 5, it is compound can to greatly improve the cement fly ash gravel pile 1
The drainability of ground capital construction base reinforced structure, therefore can be widely applied to the building lot in house.
The side wall of seamless steel pipe 4 is equipped with the reinforcing rib of multiple tracks and 4 axis parallel of seamless steel pipe, and the surface of reinforcing rib is set
There is spiral lamination.Reinforcing rib, which is arranged, can be improved the structural strength of the broken stone pile 1 with seamless steel pipe 4, be arranged on reinforcing rib surface
Spiral lamination can be improved the conjugation of broken stone pile 1 Yu seamless steel pipe 4, makes not allowing to be also easy to produce gap therebetween, improves entirety
The compactness of structure.
Drain tank 5 is metal drain tank, and the downward V-type guide groove in multiple tips is equipped in metal drain tank.By drain tank 5
Be set as improving structural strength with the metal drain tank one of V-type guide groove, two come also contribute to improve sluicing efficiency.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model, should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
