Description
Technical field
This utility model is related to foundation treatment technology field, more particularly to a kind of foundation structure.
Background technology
In construction, it is inevitable working link to excavate and reinforce and be rudimentary, with a varied topography in some constructions
In environment, boulder or solution cavity and Soft Clay often occurs.In some construction sites, basement rock is very large, and interior hollow, this
Be exactly the situation of the mutual fit of solution cavity basement rock often said, if consolidation process is not carried out to whole basement rock, base is directly done on basement rock
Plinth, the solution cavity inside basement rock can cause the inequality of earth's surface because long-time avalanche is occurred by the extruding of upper building gravity
Even sedimentation, destroys the stability in the large of building；If digging positive basement rock, solution cavity is punched, cement is carried out in solution cavity internal drainage and mixed
Solidifying earth foundation construction, then construction cost is again sufficiently expensive, and schedule delays.Therefore, apply carrying out engineering to these complicated geologicals
In man-hour, the progress of whole engineering be to not only consider, the reliability of foundation stabilization and the economy of construction guaranteed again.
The Chinese utility model of Application No. CN201120005549 discloses a kind of composite foundation structure, including soft subgrade soil
Body layer, is provided with supporting course below soft subgrade soil body layer, be provided with the mixing bed of material, be provided with least one in the mixing bed of material above soft subgrade soil body layer
Individual drill hole, drill bottom hole end are extended in soft subgrade soil body, and drill is provided with mixture in hole.The composite foundation structure construction method
Simply, but just because of excessively simply causing its bearing capacity to need further to be improved.
Utility model content
The purpose of this utility model is to provide a kind of foundation structure, and with solid and reliable structural strength, reduction is caved in
Phenomenon.
Above-mentioned purpose of the present utility model technical scheme is that：A kind of foundation structure, including soil
Layer and basement rock, soil layer are located above basement rock, and some steel pipes are vertically provided with soil layer, and steel pipe extend into horizon d from the top of soil layer
It is interior, and in steel pipe, it is marked with slurry.
By adopting above-mentioned technical proposal, soil layer is set above basement rock, due to softer for the relative basement rock of soil layer,
Therefore the pressure that buffering superstructure is applied to basement rock can be played, plays a part of to protect basement rock to prevent its breakage；In soil layer
Interior to arrange after the steel pipe in soil layer to basement rock, detached soil layer and basement rock originally are coupled together by steel pipe, improve ground
The globality of structure；The slip casting in the steel pipe is conducive to the intensity for strengthening steel pipe, makes foundation structure more stable.
Preferably, some GSZs are provided with soil layer.
All kinds of ambient soils are adapted to by adopting above-mentioned technical proposal, GSZ, is had compared with conventional grates strong
Many advantages, such as spending big, strong, anticorrosive bearing capacity, anti-aging, easy construction, long service life, arranges geotechnological lattice in soil layer
The bearing capacity of the enhancing ground of grid energy high degree, effectively constrains the lateral displacement of the soil body, strengthens the firm performance of ground, reduces
Cave in phenomenon.
Preferably, GSZ is set in parallel in the horizontal plane of differing heights.
By adopting above-mentioned technical proposal, GSZ is set in parallel in the different level in soil layer, by soil layer
It is separated into multiple modules to be protected, the soil layer in each module can obtain effective reinforcement effect, so that soil layer entirety
It is more solid firm.
Preferably, the first spontaneous recovery concrete layer is provided with above soil layer.
There is the effect for voluntarily mending a split by adopting above-mentioned technical proposal, spontaneous recovery concrete, the inside contains can give birth to
The nutrient needed the bacterial spore and bacterial growth for producing the dormancy of limestone, after corrosivity rainwater penetrates into spontaneous recovery concrete layer more
Bacterial spore can be just activated, concrete cracking part is locally filled with so as to produce limestone, Efficient software patching crack, be protected
The soil layer and basement rock of shield lower section.
Preferably, the second spontaneous recovery concrete layer is provided between basement rock and soil layer.
By adopting above-mentioned technical proposal, spontaneous recovery concrete layer is covered above basement rock protection work can be played to basement rock
With, the phenomenon that basement rock suffers breakage because of the pressure that top is built is reduced, the steadiness of protection ground increases the service life.
Preferably, the top of soil layer is provided with some filling baggy fabrics in the horizontal direction.
By adopting above-mentioned technical proposal, as soil layer is in the overall top position of ground, when current stream enters in ground
When, it is exactly more soft soil layer by water impact effect at first, after the top of soil layer arranges filling baggy fabric, filling baggy fabric can
To absorb to the current for flowing down, reduce the water content into underground layer bottom and basement rock so that soil layer can keep compared with
For solid soil property state, it is ensured that the overall construction intensity of ground.
Preferably, fine sand is filled with filling baggy fabric.
By adopting above-mentioned technical proposal, the granule of fine sand is less, forms tiny space, work as water between fine sand and fine sand
After stream is flowed into, fine sand has preferable Absorption to current, thus reduces into the water yield in underground layer.
Preferably, the top and bottom of soil layer is coated with geotextiles.
The overall structure and function of soil layer can be kept, the carrying of ground is made by adopting above-mentioned technical proposal, geotextiles
Ability is strengthened, and strengthens the structural stability of ground；Geotextiles are covered at the top of soil layer and bottom, soil layer can be made integrally more to tie
It is real firm.
Preferably, rubble is evenly equipped with soil layer.
By adopting above-mentioned technical proposal, soil layer is more soft, easily caves in, and can be made after mixing rubble in soil layer
Soil layer is overall firmer, plays a part of to tamp soil ground, reduces by caving in that soft soil causes.
Preferably, the outer ring of soil layer is with baffle plate.
By adopting above-mentioned technical proposal, the baffle plate for enclosing is set in the outer ring of soil layer, by soil layer lock ring in baffle plate, is risen
To the effect for preventing soil layer from caving in.
To sum up, soil layer and basement rock effectively can be combined into by a kind of foundation structure described in the utility model, slip casting in steel pipe
It is overall, improve globality；Soil layer compacting is fastened by geotextiles, GSZ, rubble, makes soil layer be difficult loosely, to improve overall knot
Structure intensity.
