Description
Technical field
The invention belongs to Impacts Evaluation of Urban Tunnel engineering fields and urban operating mechanism technical field, more particularly to a kind of prefabricated mixed
Solidifying soil retaining wall system.
Background technique
Slope project is in especially important status in entire great civil engineering, the reason is that slope project amount is big, technology
Difficulty is big, accident rate is high.Slope project object is rock mass or the soil body, what Rock And Soil was a naturally occurring, cannot artificially be manufactured, feature
Be: property varies in different localities, different because of when；The mankind understand cannot be detailed；Mechanics parameter can not accurately be provided；Design level is because of people
And it is different.These features, which exist, brings great difficulty to engineering construction, as a result, improper to Rock And Soil assurance, accident rate is big
(it is reported that side slope accident rate accounts for 70% or so in architectural engineering)；Design scheme is different, and cost variance is big；Geological conditions variation
Greatly, lack the slope support method of economical rationality in many cases.
Currently, tall earth fill administer in the structural body that uses mainly have: cantilever pile retaining wall, anchorage pile retaining wall, again
Power formula retaining wall, reinforced earth retaining wall, taper pile self-balancing retaining wall etc..Wherein: when gravity retaining wall height is greater than 8 meters, work
Quickly, economy is particularly poor for high retaining wall for journey increased costs；The moment of flexure of cantilever pile retaining wall is all structure types
In maximum one kind, so cost is also very high；For tall and big retaining wall, in contrast, the cost of anchorage pile retaining wall
It is lower than the above two, and taper pile self-balancing retaining wall cost is minimum, so both retaining walls are widely applied in recent years.Its
In, anchorage pile retaining wall needs anchor brace members, and taper pile self-balancing retaining wall does not depend on anchor brace members, in economy and geology item
Part, which adapts to aspect, bigger advantage.The key of taper pile self-balancing retaining wall technology is: reducing side slope using taper pile supporting and pushes away
Power；Side slope thrust moment of flexure is balanced using the recurvation square that Foot of Upper Retaining Wall gravity generates.This structure has the characteristics that reasonable stress,
Slope project cost is greatly lowered, and to the dependence very little of geological conditions, so applicability is very strong.Also just because of this
Structure, it is desirable that side slope will have constant slope (generally with plumb line angle 20 degree), it means that slope supporting will account for certain space.
But certain slope projects without slope space, the application of taper pile self-balancing barricade are just restricted.Retaining wall refers to bearing
Roadbed Soil or the hillside soil body prevent from banketing or the structure of soil deformation unstability.
Different from the armored concrete counterfort wall of integral cast-in-situ, Retaining Wall panel is due to using batch production
The mode that standard is prefabricated, in-site installation is constructed makes Retaining Wall have the advantages that its is unique, i.e., the shorter assembly duration,
And prefabricated construction quality is easy to control.In the construction that especially road grade bridge leads the way the duration in large- and-medium size cities, road shoulder retaining wall
Construction is due to by short time limit.With the limitation of Adjacent Buildings, just make it that must construct using Retaining Wall.In addition,
For those foundation conditions difference and lack building stones areas, due to its require wall it is light and small, take up an area less and foundation bearing capacity it is low,
It therefore is its optimal selection using Retaining Wall.
Retaining Wall, due to that engineering can be made to shorten the construction period, construction is to periphery social environment and ecological ring
The negative influence that border generates is smaller, thus just can be alleviated the traffic pressure of urban road construction, so, just right
There is important facilitation in construction low-carbon conservation-minded society.
Summary of the invention
