Abstract
The utility model discloses a reinforced structure is widened to weak soil road bed, include that highway subgrade, dust trade packing course, moderate strength soil layer, weak subjacent bed, stereoplasm supporting course, CFG stake, geogrid, banket layer, miniature anchor pile, characterized by: the weak subjacent bed of top for hanging down shear strength of stereoplasm supporting course, weak subjacent bed top is the moderate strength soil layer, is moderate strength soil layer top 3 5m's dust trades the packing course, dust trades the packing course top and is equipped with the highway subgrade, banket in the layer and vertically to have laid one deck or multilayer geotextile grid along the layer of banketing, during miniature anchor pile ran through geogrid and vertically inserts each soil layer, the capacity who solves the not enough problem of soft soil layer bearing capacity, road can not satisfy the needs of volume of traffic increase to overcome current highway subgrade soft soil layer and widen the not enough of reinforcement technique.
Description
Technical field
This utility model relates to a kind of soft soil roadbed widening ruggedized construction, belongs to road widening project reinforcement technique field.
Background technology
Soft layer has distribution in European and American countries, Japan, Southeast Asia and China, is characterized in that water content is high, void ratio is big, intensity is low, compressibility is high, permeability is little.Development along with national economy, a lot of highway engineerings have to be built on soft layer, the method reinforcing soft layer is a lot, but every kind of method has certain scope of application, must select according to geological condition, execution conditions, area feature and use requirement, meanwhile, along with developing rapidly of China's economy, highway effect in the national economic development is more and more prominent.But the traffic capacity of some road can not meet the needs that the volume of traffic increases, it causes the raising of waste of time and cost of transportation, has had a strong impact on the development of regional economy.Require to meet the traffic of sharp increase and improve Assessment of Serviceability of Roads, preferably for economic construction service, road being widened and becomes inevitable choice.
Utility model content
The purpose of this utility model is: for the defect of prior art, offer one is soft soil roadbed widens ruggedized construction, solve the inadequate problem of soft layer bearing capacity, the traffic capacity of road can not meet the needs that the volume of traffic increases, to overcome existing highway roadbed soft layer to widen the deficiency of reinforcement technique.
The technical solution of the utility model:
One is soft soil roadbed widens ruggedized construction, including highway subgrade, lime-soil cushion layer, moderate strength soil layer, weak substratum, hard supporting course, CFG stake, GSZ, fill stratum, miniature anchor pile, it is characterized in that: the weak substratum being arranged above low shearing strength of described hard supporting course, described weak substratum is arranged above moderate strength soil layer, described moderate strength soil layer is arranged above the lime-soil cushion layer of 3-5m, and described lime-soil cushion layer is arranged over highway subgrade；Described CFG stake stake top is positioned at bottom highway subgrade, and pile body passes described lime-soil cushion layer, moderate strength soil layer, weak substratum, and footing inserts the internal 2-3m of described hard supporting course；Described fill stratum is positioned at above lime-soil cushion layer, and in described fill stratum, the longitudinal direction along fill stratum is equipped with one or more layers GSZ；Described miniature anchor pile runs through GSZ and is longitudinally inserted in each soil layer.
The described square layout of CFG stake, pile spacing 1.6m, stake footpath 0.5m.
Described CFG stake stake top sets C25 armored concrete pile cover, pile cover size 1m × 1m × 0.3m.
When described GSZ is multilamellar, the spacing between adjacent two layers GSZ is in the range of 0.5～1.5m.
Described miniature anchor pile is deposited reinforced concrete pile.
Owing to have employed technique scheme, compared with prior art, this utility model both can play the effect of reinforcing soft ground.
