Abstract
Belong to building field, every infiltration level structure to solve the problems, such as the saturated yielding of big thickness collapsible loess foundation with level the utility model discloses a kind of seepage proof curtain for releasing collapsible loess foundation settlement by soaking.A kind of seepage proof curtain for releasing collapsible loess foundation settlement by soaking is with level every infiltration level structure, level is divided on building basis every infiltration layer, vertical grouting curtain is provided with around the building basis above infiltration layer in level, lower curtain is provided with around the collapsible loess below the infiltration layer in level.The utility model principle ensures that the lower foundation soil in basis is not soaked, so as to play the bearing capacity of original soil, does not produce saturated yielding to block the seepage water source in ground, during using pile foundation, does not produce negative friction.The utility model cost is cheap, has good environmental benefit.
Description
Technical field
The utility model belongs to building field, more particularly to a kind of antiseepage curtain for releasing collapsible loess foundation settlement by soaking
Curtain is with level every infiltration level structure.
Background technology
Collapsible loess be one kind under drying regime, there is higher-strength and compared with low compressibility, meet after water certain outer
A kind of Special Rock of intensity rapid drawdown under power effect or Gravitative Loads.It is distributed widely in China Gansu, Ningxia, Shaanxi and Shanxi
Deng Loess Plateau, wherein most representative with 03 kalimeris group loess.Collapsible loess is a kind of soil of special nature, its
Soil property is more uniform, short texture, space development.When not by water-soaked, foundation bearing capacity is higher, and compressibility is smaller.Once meet
Water and under pressure, when intensity remaining in the soil body is insufficiently resistant to the structural stress in the soil body, soil structures are rapid
Destroy, and significant depression occurs, the saturated yielding of the collapsible loess foundation soil body has great harmfulness to engineering construction, therefore locates
The method for managing collapsible loess foundation is also increasing.The method of existing processing collapsible loess foundation is divided into two kinds：One kind is
The pile foundation of yellow soil horizon of collapsibility is penetrated, another kind is elimination（Or partially remove）The settlement by soaking of the lower yellow soil horizon of collapsibility in basis.
Utility model content
The purpose of this utility model be to provide a kind of seepage proof curtain for releasing collapsible loess foundation settlement by soaking with it is horizontal every
Infiltration level structure, big thickness collapsible loess foundation soil structure is loose, space is developed to solve, and meets what intensity after water declined rapidly
Problem.
Technical solutions of the utility model are as follows：A kind of seepage proof curtain for releasing collapsible loess foundation settlement by soaking with it is horizontal every
Infiltration level structure, level is divided on building basis every infiltration layer, is provided with and hangs down around the building basis above infiltration layer in level
Straight seepage proof curtain, lower curtain is provided with around the collapsible loess below the infiltration layer in level.
Further, as first way of the present utility model, the lower curtain is native curtain, in level every in infiltration layer
Provided with horizontal leakage preventing film.
Further, as the second way of the present utility model, the lower curtain is native curtain, in vertical grouting curtain
With longitudinal antiseepage film is provided with native curtain, in level every being provided with horizontal leakage preventing film in infiltration layer.
Further, as the third mode of the present utility model, the lower curtain is native curtain, in vertical grouting curtain
With longitudinal antiseepage film is provided with native curtain, in level every being provided with horizontal leakage preventing film and reinforcing layer in infiltration layer.
Further, above-mentioned antiseepage film is geomembrane.
Further, above-mentioned reinforcing layer is geotextiles or GSZ.
Further, it is compacted curtain as the 4th kind of mode of the present utility model, lower curtain, is provided with compaction pile；
It is horizontal every infiltration layer be concrete every infiltration layer.
The utility model principle ensures that the lower foundation soil in basis is not soaked, so as to send out to block the seepage water source in ground
The bearing capacity of original soil is waved, does not produce saturated yielding, during using pile foundation, does not produce negative friction.The utility model cost is cheap, tool
There is good environmental benefit.
