Description
Technical field
The invention belongs to hazards control field, more particularly to a kind of " rice " type stake core draining anti-slide pile structure and apply
Work method, suitable for the hydrodynamic force type reinforcing side slope technique by Hydrographic Factors such as library water and rainfalls.
Background technique
Landslide is essentially that side slope slopes are progressive, process of dynamic failure, and influence factor shows complicated and diversity
The characteristics of, mainly by various synthesis such as topography and geomorphology, formation lithology, geological structure, rainfall, engineering construction disturbance, times
It influences, therefore landslide control engineering is often a complicated system engineering.Currently, many to the administering method on landslide, such as: gear
Cob wall, anchor pole cut slope off-load and back-pressure, friction pile etc..Wherein, friction pile has flexible arrangement, construction is simple, disturbs to landslide
The advantages that small, therefore the extensive concern by engineering circles and academia.
Initially, when analysis, checking Landslide Stability, the adverse effect factor of underground water is but often ignored, it is believed that does not have
The necessary water drainage of arrangement meticulously, it is even contemplated that whether there is or not water drainages is all unimportant.In fact, friction pile is improving slip mass antiskid
While stability, the seepage channel of slopes internal water is decreased, to increase potential landslide danger to a certain extent
Danger.That is friction pile has resistance infiltration effect to gliding mass seepage flow, has raised gliding mass water level, increases gliding mass self weight, and make
The decline of the cohesive strength and internal friction angle of gliding mass and slider bed, Landslide Stability decline, sliding force increase.Based on this, slip mass is carried out
Hydrophobic and slopes drainage, for ensuring that the stabilization of slip mass plays an important role, so draining friction pile meet the tendency of and
It is raw.For list from shape, draining friction pile can be divided into tubular pole and square pile.The smooth outer surface of tubular pole is rounded, is especially making
It is for friction pile in use, small with the frictional force of soil, have to increase project cost using the big tubular pole of outer diameter in many engineerings.
Furthermore the anti-bending strength of thin-wall pipe pile is poor, and the shearing resistance, tensile property of especially pile body are poor, brings larger peace to landslide control
Full hidden danger.It is such as " a kind of application No. is 201220581962.7 " a kind of draining friction piles " and application No. is 201610832857.9
Upper side slope drains friction pile " have the shortcomings that anti-bending strength is poor.And compare relative to tubular pole performance, square pile has outer surface
Product is big and at square, this means that square pile can obtain bigger bearing capacity than tubular pole under the conditions of same geology.Furthermore square pile
Theoretical calculation shearing resistance can be 2~3 times of same tubular pole, while also having construction breakage rate low, shock resistance is strong, can be easy
The fast connector of non-solder is developed, all-weather construction can be truly realized, construction can be quick.Therefore numerous squares drain antiskid
Stake patent emerges one after another.But some patents pursue drainage effect simply and ignore its anti-bending strength.Such as application No. is
201510252389.3 " a kind of draining friction piles and its construction method for automatically adjusting water level ", in order to reach automatic adjustment water
The purpose of position is provided with rectangle hollow pile body, its anti-bending strength is caused to be had a greatly reduced quality.In addition, application No. is 201810078596.5
" hollow draining anchor draws friction pile and its construction method ", the system is by friction pile, anchor drawing device, seepage well and pumping system group
At structure is extremely complex, and construction procedure is up to 33 steps, very cumbersome.
Summary of the invention
In view of the deficiencies of the prior art, the invention proposes the draining anti-slide pile structures and construction party of a kind of " rice " type stake core
Method, the friction pile cross section are square, using steel reinforcement cage by the rectangular solid pile bottom in lower part, the rectangular outer pile lining in top and top " rice "
The connection of stake core is integral in type, substantially increases the globality and its bending resistance shear behavior of friction pile.It is filled using permeable aggregate
Top pile body collecting space, deflector hole and drain hole realize the function of draining.Furthermore the use of geomembrane and drainage blanket
Perfection overcomes the risk of its draining failure in friction pile use process.Furthermore the draining friction pile both can with cast in situs,
Can be prefabricated, working procedure is simple, flexible operation.
