Description
Technical field
The present invention relates to a kind of ratio of slope mild rich neatly slope retaining structure and construction method thereof.
Background technology
Landslide, as a kind of natural calamity, all brings the loss of huge life and property every year to the whole world, cause the reason on landslide a lot.Landslide is conventionally accompanied by the natural calamities such as heavy rain, earthquake and occurs.Soil occurs to soften to cause paroxysmal landslide under certain underground water and stress condition.If lasting time of rainfall is long, the force of rain is large, and the slope table soil body of certain depth moves closer to saturation state, the shear strength of the soil body weakens rapidly, and may below surface, slope, form higher temporary groundwater table, cause local penetration and destroy, even whole landslide.
At present, the improvement method for rich neatly slope comprises the improvement of surface water and the improvement of underground water.Administering surface water is mainly to make catchwater around at sliding mass, makes surface water can not enter within the scope of sliding mass; Within the scope of landslide, build various gutters, surface water is discharged beyond sliding mass scope, should carry out the seepage control measure of irrigation canals and ditches simultaneously.Leveling earth's surface, the loosening ground of filling crack and compacting, carries out every infiltration layer, reduces under surface water and oozes and make it import as early as possible gutter, gets rid of gliding mass.Administer the underground water in sliding mass, for the spring of exposure and wetland etc., make gutter or sewer, water is drawn outside sliding mass; Sliding mass leading edge, groundwater table activity in Chang Yinpo body and soft, moist, causes that slope body caves in, and can make side slope sewer drainage; Note bank protection and vegetation, strengthen evaporation capacity, guarantee domatic dry.When if the water on sliding zone is pressure-bearing supply from bottom to top, adopt more Huo Ping hole, blind hole underground water is drained or dewatering below slide plane.In order to get rid of deep phreatic water, under soil layer and rock stratum operating mode, all can adopt long horizontal drilling.Inside and outside region, landslide, near the most concentrated location of underground water, collecting well can be set, for concentrating, collect on bedrock surface and near underground water.Except earth's surface and the underground water on landslide, administer, conventionally also carry out retaining structure protection.Retaining structure is being brought into play more and more important effect in the protection of landslide.Retaining structure comprises support and the anchor structures such as retaining wall, antislide pile, prestress anchorage cable, is for supporting, reinforcing landslide, prevents that it from collapsing sliding to keep stable a kind of building.
Current in the mild rich neatly slope retaining structure of ratio of slope, the rare retaining structure with integral rigidity, even if having integral rigidity, as retaining wall etc., its form of structure does not possess the feature that materials are economized yet.Therefore, be badly in need of at present a kind of easy to implement, drainage effect good, there is the mild rich neatly slope retaining structure of ratio of slope that integral rigidity and materials are saved.
Summary of the invention
Existing in the mild rich neatly slope retaining structure of ratio of slope in order to overcome, the rare retaining structure with integral rigidity, even if there is integral rigidity, as retaining wall etc., its form of structure does not possess the deficiency that materials are economized yet, the present invention aims to provide a kind of ratio of slope mild rich neatly slope retaining structure and construction method thereof, and this retaining structure and construction method thereof are easy to implement, drainage effect good, have integral rigidity and materials are saved feature.
To achieve these goals, the technical solution adopted in the present invention is:

-arrange antislide pile more, every row's antislide pile arranges to X-direction along horizontal wall inscription, every row's antislide pile is comprised of many antislide piles; The top of adjacent two antislide piles is fixedly linked by tie-beam, and makes each antislide pile be connected to form rigidity antiskid body; The vertical every antislide pile of arranging is placed in corresponding antislide pile installing hole;
-collector drain, integral body is arranged to X-direction along horizontal wall inscription, is arranged between adjacent two row's antislide piles, and below the tie-beams between adjacent two row's antislide piles.
Be below the technical scheme of further improvement of the present invention:
In order to facilitate the discharge of water, described collector drain is in tilted layout to X-direction along horizontal wall inscription, slope >=2%.
Preferably, described antislide pile is reinforced concrete pile.
In order to guarantee the stability of antislide pile, the length that described antislide pile is placed in slide bed is at least 1/3 of antislide pile length.
Preferably, the cross section perpendicular to its length direction of described collector drain, YZ cross section is the circle of rectangle or the diameter 1.5m ~ 2.5m of length of side 1.5m ~ 2.5m.
Further, in described collector drain, fill building stones, between building stones and collector drain inwall, be provided with geotechnological layer of cloth.
Another technical scheme of the present invention is to provide the construction method of the mild rich neatly slope retaining structure of a kind of the above ratio of slope, is characterized in, comprises the steps:
1), along road direction a plurality of antislide pile installing holes that spud on landslide, support formwork erection between antislide pile installing hole;
2), the reinforcing cage of antislide pile is put into each antislide pile installing hole, the end of tie-beam and reinforcing cage top are fixed;
3), to grouting in each antislide pile installing hole, form antislide pile;
4), adjacent two rows, excavate collector drain between antislide piles, and lay one deck geotextiles in collector drain inner side, then building stones are filled collector drain.
The excavation direction of described collector drain is identical with road direction, and in collector drain, 2-4 cubes of building stones of every filling once compress compacting, and then continues to fill, until fill up building stones in whole collector drain.
The concrete steps that form antislide pile to grouting in each antislide pile installing hole are: first that slurry agitation is even, sieve, at the bottom of the slurries after sieve are delivered to the hole of antislide pile installing hole, then by Di Fanchu aperture, hole, when aperture is overflowed slurries or stack and stopped exhaust, stop slip casting; Finally pour into again tie-beam.
Compared with prior art, beneficial effect of the present invention is: the present invention is by being rigidly connected tie-beam and antislide pile, therefore each is rigidly connected, therefore each antislide pile has formed rigid unitary together, can be common between each antislide pile, thus can play better the effect of side slope anti-sliding support.The end of antislide pile connects with concrete beam, and its design feature is that the large and materials of rigidity are economized, and is a kind of structure of economical rationality.
Collector drain guarantees certain slope, can guarantee that draining is unobstructed, is unlikely to occur the not smooth problem of current alluvial discharge of horizontal drainage gallery.In gallery, fill rubble and compacting, the porosity of rubble is large, is convenient to draining, and through compacting, can guarantee subgrade strength.
In a word, retaining structure of the present invention can prop up gear to landslide and reinforce, and guarantees that the water in landslide discharges in time, guarantees the stability coming down.This ruggedized construction rigidity is large, work material-saving, easy to implement, respond well, cost is low, wide accommodation.
