Abstract
The utility model is related to a kind of foundation structures of serious Collapsible Loess District basement process, including the element earth pile being set in the collapsible loess soil body, the cushion lime being covered on element earth pile, the rigid pile through cushion lime and between element earth pile, the pile foundation support table being connected in rigid pile and with rigid pile and the foundation beam being connected with pile foundation support table on pile foundation support table, back fill course is covered on cushion lime.The utility model using the above structure can be to avoid loess immersion saturated yielding, while increasing substantially bearing capacity of pile foundation, and the safety of pile foundation is substantially increased under the premise of reducing basic cost.
Description
Technical field
The utility model is related to a kind of foundation structures of serious Collapsible Loess District basement process.
Background technology
In the Base foundation design of the serious Site of Collapsible Loess of big thickness, be faced with conventional foundation treatment mode without
The problems such as method eliminates so deep collapsibility of loess, and foundation treatment depth cannot meet code requirement.When using rigid pile foundation
It must consider not carry out the negative friction of basement process part collapsible loess, be to ensure bearing capacity of pile foundation, Shi Biyao in this way
Stake is lengthened, stake diameter is increased or increases stake number, engineering economy is very poor.
Invention content
For under such special geologic condition, the utility model provides a kind of serious Collapsible Loess District basement process
Foundation structure, the structure can increase substantially bearing capacity of pile foundation in the case where identical stake is long, big under the premise of reducing basic cost
The big safety for improving pile foundation.
To achieve the above object, the utility model adopts the following technical solution：A kind of serious Collapsible Loess District ground
The foundation structure of processing, including the element earth pile being set in the collapsible loess soil body, the ash being covered on element earth pile
Soil padding, the rigid pile through cushion lime and between element earth pile, the stake being connected in rigid pile and with rigid pile
Base cushion cap and the foundation beam being connected with pile foundation support table on pile foundation support table, are covered with back fill course on cushion lime.
Pipeline box culvert is embedded in the back fill course of the utility model.
In the above-mentioned technical solutions, element earth pile filler material is clay.
In the above-mentioned technical solutions, cushion lime is generally 500mm thickness.It may be used 3:7 dirt, ranging from entire ground
Process range.
In the above-mentioned technical solutions, rigid pile is reinforced concrete pile or other types pile foundation.
In the above-mentioned technical solutions, pipeline box culvert is reinforced concrete pipiline box culvert.
The utility model using the above structure can be to avoid loess immersion saturated yielding, while increasing substantially bearing capacity of pile foundation,
The safety of pile foundation is substantially increased under the premise of reducing basic cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of this practicality.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment is described further this Ground Treatment Schemes utility model.
As shown in Figure 1, the utility model includes the element earth pile 1 being set in the collapsible loess soil body, is covered in element
Cushion lime 2 on native compaction pile 1, is located at rigid pile 3 at the rigid pile 3 through cushion lime 2 and between element earth pile 1
The upper and pile foundation support table 4 being connected with rigid pile 3 and the foundation beam 5 being connected with pile foundation support table 4 on pile foundation support table 4, dirt pad
It is covered with back fill course 6 on layer 3.Structural column 9 is connected on foundation beam 5.
The pipeline box culvert 7 for putting pipeline 8 is embedded in the back fill course 6 of the utility model.
In the above-mentioned technical solutions, element earth pile filler material is clay.
In the above-mentioned technical solutions, cushion lime is generally 500mm thickness.It may be used 3:7 dirt, ranging from entire ground
Process range.
In the above-mentioned technical solutions, rigid pile is general reinforced concrete pile or other types pile foundation.
In the above-mentioned technical solutions, pipeline box culvert is general reinforced concrete pipiline box culvert.
Specific implementation step is as follows：
First within the scope of the proposed place of building, expires hall according to certain spacing and arrange element earth pile 1；Wait for that plain soil squeezes
After close stake 1 detects qualification, then 500mm thickness 3 is completely spread on it:7 cushion limes 2；Rigid pile of constructing again 3；Wait for that the detection of rigid pile 3 is closed
It constructs again after lattice pile foundation support table 4 and foundation beam 5；Then construction backfill 6 and equipment pipe external wrapping concrete box culvert 7, then construct
Superstructure（Pipeline 8, structural column 9）.
After implementing according to the above technical scheme, when rigid pile Design of Bearing Capacity, element earth pile 1 handles saturated yielding in depth bounds
Property loess can be included in positive friction by native parameter value under natural conditions, in element earth pile 1 bottom to rigid pile bottom range
Untreated collapsible loess can be included in positive friction by native parameter value under saturation state；It does not account for not only so untreated
The negative friction of part collapsible loess is included in its positive friction instead, to which bearing capacity of pile foundation greatly improved.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
It is confined to this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.
