Abstract
The utility model belongs to building engineering field, discloses a kind of novel reinforcement cushion composite foundation, the sand stone layer is in permanent bottom of banketing；The reinforcement cushion is in sand stone layer bottom, for there is larger frictional resistance between reinforcement cushion and surrounding sandstone, limits shearing, lateral extrusion and the protuberance of foundation soil on the whole, constrains the lateral deformation of soft clay；The concrete core sand stone mar is in reinforcement cushion bottom, for bearing vertical horizontal load.The utility model utilizes the substrate bed course that there is the flexible reinforcement bed course of certain thickness, certain extensional rigidity, certain modulus and anti-crawl agentdefiection stiffness to make embankment, bear and transmit embankment, it is homogenized base stress, reasonable distribution asks soil in stake top and stake, constrain the lateral deformation of ground, prevent pile body bending failure, guarantee gives full play to the bearing capacity of stake, the corresponding load pressure for reducing stake and asking soil, and meets the strict demand of high-moisture, high organic content area to settlement after construction, do not easily cause uneven subsidence.
Description
Technical field
The utility model belongs to building engineering field more particularly to a kind of novel reinforcement cushion composite foundation.
Background technology
The compound soil body that reinforced earth is made of soil and muscle body.Reinforced bands or TGXG are laid with during fill construction
Or the reinforcement materials such as geotextile, to enhance the tension, shearing strength and overall stability of the soil body.It is mainly used for dykes and dams and earth-retaining
In works.But existing reinforcement cushion composite foundation be easy to cause fracture and the failure by shear of bed course, floor space compared with
Greatly, do not allowing the place excavated that cannot construct.
In conclusion the problem of prior art is deposited is：Existing reinforcement cushion composite foundation be easy to cause the fracture of bed course
And failure by shear, and the strict demand of high-moisture, high organic content area to settlement after construction cannot be met, it be easy to cause
Uneven subsidence.
Utility model content
In view of the problems of the existing technology, the utility model provides a kind of novel reinforcement cushion composite foundation.
The utility model is realized in this way a kind of novel reinforcement cushion composite foundation include permanently banket, sand stone layer,
Reinforcement cushion, concrete core sand stone mar.
The sand stone layer is in permanent bottom of banketing；
The reinforcement cushion is in sand stone layer bottom, for there is larger frictional resistance between reinforcement cushion and surrounding sandstone, from
Shearing, lateral extrusion and the protuberance for limiting foundation soil on the whole, constrain the lateral deformation of soft clay；
The concrete core sand stone mar is in reinforcement cushion bottom, for bearing vertical horizontal load.
In the above-mentioned technical solutions, using with certain thickness, certain extensional rigidity, certain modulus and anti-crawl agentdefiection stiffness
Flexible reinforcement bed course makees the substrate bed course of embankment, bears and transmit embankment, is homogenized base stress, reasonable distribution in stake top and
Soil is asked in stake, constrains the lateral deformation of ground, prevents pile body bending failure, is ensured the bearing capacity for giving full play to stake, is accordingly reduced stake
It asks the load pressure of soil, and meets the strict demand of high-moisture, high organic content area to settlement after construction, do not easily cause
Uneven subsidence.
Further, reinforcement cushion includes geogrids layer, geotextile layer.
The geogrids layer is polyester warp-knitting polyester TGXG.
The geotextile layer carries out binding suture with the geogrids layer.
Further, the concrete core sand stone mar includes the stake of prefabricated reinforced concrete core and sandstone shell.
The sandstone shell outsourcing prefabricated reinforced concrete core stake.
Description of the drawings
Fig. 1 is the novel reinforcement cushion composite foundation structure schematic diagram provided in specific embodiment of the present invention；
Fig. 2 is the reinforcement cushion structural schematic diagram provided in specific embodiment of the present invention；
In figure：1, it permanently bankets；2, sand stone layer；3, reinforcement cushion；4, concrete core sand stone mar；5, geogrids layer；6, native
Work layer of cloth；7, prefabricated reinforced concrete core stake；8, sandstone shell.
Specific implementation mode
As shown in Figure 1, the novel reinforcement cushion composite foundation includes：Permanent banket 1, sand stone layer 2, reinforcement cushion 3, concrete
Core sand stone mar 4.
The sand stone layer 2 is in permanent 1 bottom of banketing；
The reinforcement cushion 3 is in 2 bottom of sand stone layer, for there is larger frictional resistance between reinforcement cushion 3 and surrounding sandstone,
Shearing, lateral extrusion and the protuberance for limiting foundation soil on the whole, constrain the lateral deformation of soft clay；
The concrete core sand stone mar 4 is in 3 bottom of reinforcement cushion, for bearing vertical horizontal load.
Further, reinforcement cushion 3 includes geogrids layer 5, geotextile layer 6.
The geogrids layer 5 is polyester warp-knitting polyester TGXG；
The geotextile layer 6 carries out binding suture with the geogrids layer 5, as shown in Figure 2.
Further, the concrete core sand stone mar 4 includes the sandstone shell of prefabricated reinforced concrete core stake 7 and prefabricated reinforced concrete core stake periphery
8。
8 outsourcing prefabricated reinforced concrete core stake 7 of the sandstone shell.
In present embodiment, the flexibility with certain thickness, certain extensional rigidity, certain modulus and anti-crawl agentdefiection stiffness is utilized
Reinforcement cushion makees the substrate bed course of embankment, bears and transmit embankment, is homogenized base stress, and reasonable distribution is asked in stake top and stake
Soil constrains the lateral deformation of ground, prevents pile body bending failure, ensures that the bearing capacity for giving full play to stake, corresponding reduction stake ask soil
Load pressure；The drainage channel effect of sandstone shell is the weak cohesive soil ground of concrete core sand stone mar compound foundation method processing saturation
One of main function.Core stake sandstone shell shortens drainage distance as the vertical drainage body in ground, so as to accelerate stake to ask
The rate of consolidation of soil, accelerates gain in strength at accelerated sedimentation development, effectively improves the bearing capacity that soil is asked in stake, sinks after effectively eliminating work
Drop effectively meets end of the bridge section bearing capacity and eliminates the requirement of settlement after construction.
Thickness, tensile strength, modulus and the anti-crawl agentdefiection stiffness of flexible reinforcement bed course are arranged as required to.
The above is only the better embodiment to the utility model, not makees any form to the utility model
On limitation, every any simple modification made to embodiment of above according to the technical essence of the utility model is equivalent to become
Change and modify, is all within the scope of the technical scheme of the utility model.
