Description
Technical field
The present invention relates to technical field of civil engineering more particularly to it is a kind of have both drainage and enhance bending resistance sink ability it is compound
Structure and preparation method thereof.
Background technique
In city when development & construction, it usually needs the processing such as dug, filled out, rammed to developing zone and forming stratum.By digging,
Fill out and the stratum formed after tamping and natural stratum it is widely different, so be known as remodeling stratum.It the various buildings in city and constructs
Object is all built in remodeling stratum or above it.
For a long time, the various motor vehicle major trunk roads in city, pavement, Entertainment Plaza, station even multi-story structure bottom
Floor often meet with the rapid hair that several people are dead, injure huge property loss caused to collapse disaster.This kind of earth's surface before being collapsed upon generation
There is no appreciable sedimentation, hole of collapsing appears to be upright tubulose in geometric shape.
It is that there are large volume of cavities in stratum that rapid hair property, which collapses the basic reason of generation,；Earth's surface is without heavy before collapsing generation
It drops phenomenon and the pitted surface that collapses is upright, it is meant that stratum does not have flexure (flexure) deformability.
Occur the cavity for causing top to collapse in stratum, it is most probable the reason is that forming flowing water via seepage flow derivative in stratum
Channel.Certain position filler particles are constantly taken away through channel by flowing water in stratum, accumulate over a long period to be formed with large volume of
Cavity.
Presently relevant earth working material performance is single, the result added such as TGXG, geotechnical grid in stratum filling construction
It is to increase local strength, geotextiles function only as water filtering function.In order to prevent the generation that the property sent out collapses suddenly, need to research and develop a kind of same
When have both drainage and enhance stratum flexure ability composite geotextile material and corresponding building technology.
Summary of the invention

3, it is criss-cross arranged inside frame every 500mm and reinforces buckling device, keep bamboo reinforcement net 3 and geotextiles 4 close
It fastens, forms complete monolithic geotechnique having a size of 2m × 2m and reinforce composite material.
The construction technology of quick-jointing of the present invention is as follows:
1, when remolding stratum filling construction, layer position is arranged according to the geotechnological reinforcement material of setting, by earthwork composite material
It is successively laid on the entire packing layer being compacted piecewise；
2, adjacent monolithic earthwork composite material is overlapped according to the overlap length of 20cm, utilizes upper and lower connection in lap-joint
Knot snap-gauge (snap-gauge 6 will be coupled and is coupled all alignment of prefabricated connecting pore 8 of snap-gauge 7, bolt 10 will be coupled and pass through prefabricated connecting pore 8,
Will two sheet material mutually lockings) make adjacent monolithic geotechnique reinforce composite material and interconnect into extend completely across answering for embankment region
Condensation material adding layers；
3, the filler → compacting → that successively paves in adding layers paves filler → compacting ..., fills formation thickness to next
Composite material adding layers are arranged according to process above in a composite material adding layers position；
4, the reciprocal above circulation constructs the remodeling stratum to be formed and collapse function with the rapid hair property of prevention.
The above is only a specific implementation examples of the invention, not delimit the scope of the invention, in design of the invention
Any modifications, equivalent replacements and improvements with being done within principle, belong within protection scope of the present invention.
