Description
Technical field
The utility model relates to construction work foundation treatment technology field, is specifically related to a kind of foundation structure of combining employing piling prepressing and heavy tamping treatment.
Background technology
At present, for the soft foundation be made up of large area mucky soil, silt soil, conventional processing method mainly contains: preloading, change and fill out Sand-gravel-cushion Technioue, dynamic compaction.The ground larger for hole and water content weak cohesive soil ground within the specific limits, tamping or strong rammer can be adopted, its principle is that soil layer is under huge impact energy effect, very large pressure and shock wave is produced in soil, soil body hole is caused to compress, produce the good drainage channel in crack in certain depth around tamping point, the pore water in soil (gas) is discharged smoothly, the rapid consolidation of the soil body; Pounding Method process groundwork bearing capacity can obtain certain raising, and compressibilty can reduce by 200% ~ 1000%; When soft layer thickness is not very large, soft layer within the scope of weak soil partly or entirely can be excavated, then change the material (the gravel material that normally seepage of water is good) filling out the larger soil of intensity or good, the non-corrosive property of other stability and be called to change and fill out or Sand-gravel-cushion Technioue; The economical and practical height of this method process is generally 2 ~ 3m, if soft layer thickness is excessive, then adopts cushion can increase the side of abandoning and get earth volume and increase engineering cost; Preloading, be before engineering construction with the filled load being more than or equal to design load, impel ground to shift to an earlier date consolidation settlement to improve the intensity of ground, reduce settlement after construction.But, part of the foundation process engineering, incorrect according to above-mentioned single processing method, consider engineering cost, construction period and construction technology difficulty, select to combine and adopt piling prepressing and heavy tamping treatment construction technology to obtain new foundation structure form, have important practical significance.
Utility model content
For achieving the above object, the technical solution adopted in the utility model is: a kind of foundation structure of combining employing piling prepressing and heavy tamping treatment, in the process range of described foundation structure, comprise duricrust soil layer, coarse sands layer, silt soil strata, mud, gutter, sand drain, process border; Described duricrust soil layer is the hard soil body, adds carrier, simultaneously for the heavy-duty machinery walking surface layer of Foundation Treatment as the construction surface layer of heavy tamping treatment and piling prepressing; Described coarse sands layer selects the grit material with good water seepage function, as the radial drainage layer of foundation structure, adds carrier simultaneously also as piling prepressing; Described silt soil strata and mud are the initial pending soil layer of foundation structure; Described gutter and sand drain are the longitudinal drainage structure of foundation structure; Process border can be set to concrete grey and stir diaphragm wall.
As preferably, described duricrust soil layer is the hard soil body of 1-3 rice thickness, and preferably adopt the clay being beneficial to the construction of insert row water pipe, the described hard soil body can not select the building debris without pulverization process, avoids affect gutter intubate and constructs.
As preferably, described gross sand thickness is 1-5 rice.
As preferably, it is 0.6-1.5 rice that described concrete grey stirs continuous wall body thickness, and the degree of depth is 6-15 rice.
As preferably, the construction process required by the utility model structure and technique are: first on silt soil strata, successively lay coarse sands layer and preset sand drain structure; Then on coarse sands layer, adopt intubate machinery to carry out the construction of gutter intubate; On coarse sands layer, successively lay duricrust soil layer again, rezone and repeatedly carry out heavy tamping treatment construction.
Accompanying drawing explanation
Fig. 1 is structural profile schematic diagram of the present utility model.
Fig. 2 is the utility model coarse sands layer gutter and sand drain location arrangements schematic diagram.
Wherein: 1 is duricrust soil layer, 2 is coarse sands layer, and 3 is silt soil strata, and 4 is mud, and 5 is gutter, and 6 is process border, and 7 is sand drain.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is further described.
Consult Fig. 1, Fig. 2, a kind of foundation structure of combining employing piling prepressing and heavy tamping treatment, concrete enforcement comprises duricrust soil layer 1, coarse sands layer 2, silt soil strata 3, mud 4, gutter 5, process border 6, sand drain 7.
In concrete enforcement, duricrust soil layer 1 is the hard soil body of 1-3 rice thickness, and preferably adopt the clay being beneficial to the construction of insert row water pipe, the described hard soil body can not select the building debris without pulverization process, and avoiding affects the construction of gutter intubate.
In concrete enforcement, coarse sands layer 2 selects the grit material with good water seepage function, and the thickness of described coarse sands layer 2 is 1-5 rice, as the radial drainage layer of foundation structure, adds carrier simultaneously also as piling prepressing.
Described silt soil strata 3 and mud 4 are the initial pending soil layer of foundation structure; Described gutter 5 and sand drain 7 are the longitudinal drainage structure of foundation structure; Process border 6 can be set to concrete grey and stir diaphragm wall.
In concrete enforcement, concrete grey stirs continuous wall body thickness can be designed to 1.2 meters, and the degree of depth is 12 meters.
In concrete enforcement, the construction process required by the utility model structure and technique are: first on silt soil strata 3, successively lay coarse sands layer 2 and preset sand drain 7; Then on coarse sands layer 2, adopt intubate machinery to carry out the construction of gutter 5 intubate; Gutter 5 on coarse sands layer 2 and the location arrangements of sand drain 7 can select quincuncial pile shape to be staggeredly arranged.
After gutter 5 intubate has been constructed, more successively lay duricrust soil layer 1 on coarse sands layer 2, rezone and repeatedly carry out heavy tamping treatment construction, till the designing requirement reaching foundation treatment engineering.
