Description

A kind of save the casting method expecting anti-skidding retaining wall

1, technical field: be applicable to highway, railway, the piece of smooth land, storehouse bank, river levee, seashore and the retaining wall of harnessing landslide, this Planting retaining wall is to form with little steel bar concrete casting, saves the most very much material, and the firmest, only with common gear The material of 1st/to five/3rd of cob wall, and relatively common retaining wall more than ten times is firm, namely triangle draws Bar end and the how far retaining wall with regard to quite a lot of thickness of distance of retaining wall, and can not open down and promote；Solve retaining wall Thickness is little and height great Yi is opened and a difficult problem for slip.

2, technical background: commonly use at present has tie bar type retaining wall, counterfort retaining wall, cantilever retaining wall etc., That adds nearest also patent of invention has " debris flow resisting wall ".Rod-pulling type barricade has root within the walls, but underfooting does not has root.Buttress type gear soil Although wall has counterfort in succession, but inner face and underfooting do not have foundation, especially use on abrupt slope, mountain area, under the removing table soil rear foot are again Abrupt slope, by the biggest for peaceful for abrupt slope quantities, and it is the biggest, because there being steep slabstone in it to return Yunnan quantities；In mountain area Building road and rail always has steeper slope, if ground not being dug flat, as comprehensive whole engineering Offshore street Lee of storehouse, Fengjie County bank Family's ditch, to Yangtze Bridge section, need not peaceful loosen the soil, but the method filled and led up with backfill soil, top waters the end of counterfort wall again Plate, comes interim or when meeting extreme rainfall at heavy rain, subsoil water saturated too time can entirety slide,.Just should in this case The spud pile of this use debris flow resisting wall, beats stake in below hard mountain, on counterfort end also should with turnover stake, do not allow retaining wall to Outer and slip；What no matter you rammed is the tightest, and embankment always also has sedimentation, and embankment is the thickest, settle the most, abrupt slope is filled and led up, and always loosens the soil Being that outside is thick, the inside is thin, then outside will settle much, also some local soil be below slope slabstone he will whole slide, Common people cry by ship.Some place of above-mentioned engineering has poured out much to outside, if meet heavy rain or extreme weather it is possible to There is the danger of big slip.And for the most empty foot in outside, being filled with the too many cubic metre of earth and stone, to occupy Three Gorges Reservoir in storehouse the biggest Storage capacity.Therefore, I has new departure as follows:

3, summary of the invention: in order to make retaining wall the most outwards open down or outwards entirety skids off, I combines debris flow resisting wall Make the new retaining wall being exclusively used in Bao Kan, be called " joint expects anti-skidding retaining wall, " abbreviation " joint material wall ".The three of this retaining wall Dihedral pull bar is similar with the triangle rubbish bar (hereinafter referred to as triangular draw bar) of debris flow resisting wall, (genus prior art).Shingle nail with hold up Wall type retaining wall the same outer surfaces brilliance (have accompanying drawing attached).The circuit of retaining wall itself can the most also can inside and outside bend, gear soil Foundation is the most up and down；Can be high or low.Dipping and heaving and interior outside sweep, bend with landform and rise and fall.Triangle pull bar is (in figure 2) length to determine according to the height of retaining wall, retaining wall height triangular draw bar also will be longer, thick.Such as keep off The high 2 meters of pull bar length of cob wall 1 meter, gear 2 draws the ratio of 1 or 1: 1.The triangular draw bar of this retaining wall sets one at a certain distance, The namely pull bar of the counterfort (prior art) of counterfort wall, such as: three meters, five meters or ten meters or farther, if one Pull bar.In a word, see the thickness of retaining wall, the thickest then can be every remote；Retaining wall height will set thickness, and the thinnest also to have 30 lis About meter, thickness can design as one sees fit.Retaining wall height does not limits；Retaining wall is extra-high, also can triangular draw bar tail end be set to upwards straight Angle, until on to suitable height time again to retaining wall direction tiltedly on go, pull bar is the most triangular in shape, say, that draw below stalk end Not being triangle, and be square, this square flush being also intended to is fastened with anti-skidding, at this moment anti-skidding fasten will towards retaining wall, with Retaining wall is flat pattern；The hypomere being exactly pull bar is flat pattern four limit type with retaining wall, and epimere is the most triangular in shape.This is at triangular draw bar Triangular draw bar can be set shorter time oversize, and end retainer to be set up defences；Anti-skid bolt at this moment with retaining wall flat pattern, pin gear Cob wall, is allowed to keep balance.Setting a pile at each triangular form pull bar with retaining wall intersection, be slide resistant pile, straight cutting underground is deep In soil layer or in rock.The diameter of this pile can be more than retaining wall and pull bar thereof；Because it to prop up the gear soil in the middle of two pull bars Wall the backfill tension force of the cubic metre of earth and stone, thrust.With surface plate outside retaining wall so that it is brilliance is attractive in appearance；Also can gear between two pull bars Post slide resistant pile is set up under cob wall；Retaining wall also to stay the suitable slope that presses down simultaneously, and the reinforcing bar of retaining wall and triangular draw bar intersection is wanted Knot jail, hook the main reinforcing bar flat pattern of triangular draw bar to enter on the reinforcing bar of slide resistant pile or at the straight cutting of retaining wall along pull bar terrace again Add welding；The other end of reinforcing steel bar of pull rod is transferred as pedestal pile or adds welding；Setting by inner one end of triangle pull bar turns Roll over pedestal pile and anti-skid bolt or both are with setting, it is possible to optionally one.Retaining wall and anti-skid bolt flat pattern arranged side by side, centre is drawn by triangle Bar, plane H-shaped (triangle pull bar and retaining wall are three-dimensional shapes)；Anti-skid bolt should water and build up comb antiform shape, thick middle, and two Head and both sides are thin, and front plate is put down, and wide first considers.And rectangular with the terrace of triangular draw bar, preferably anti-skidding by the limit of neighbour Bolt links into an integrated entity.Triangular draw bar can also ask that two sides respectively expands more than 30 centimetres and do not increases pulling force as Padfoot, but not below Can be the widest, the widest can affect back settlement of fill.Unlike debris flow resisting wall: add slide resistant pile, turnover stake without base plate With increase retainer of also setting up defences on square pull bar, square drawhead below anti-skid bolt, Padfoot and three foot pull bars.Add and draw Power.Highway, railway, river levee, seashore etc., with the opposite less two-sided retaining wall told of distance, can connect relative square pull bar After one, both sides exert oneself and use anti-skid bolt.Material is more less than counterfort wall, few is removing base plate, this under the conditions of, square Without turnover stake under pull bar；And keep off thrust and tension force is suitable with debris flow resisting wall.

Steep slabstone sets retaining wall, in addition to slide resistant pile divided into by each pull bar, also retaining wall underfooting is blasted foundation trench, make Do not slide under retaining wall footing, and the tail end of triangular draw bar upwards can be raised with landform, but needed for high can not removing road surface.And suitable Several turnover pedestal pile is set up below triangular draw bar, i.e. every 1.5 meters or two meters or farther set a turnover pedestal pile, and this The retaining wall triangular draw bar planted on steep slabstone to set closeer, can not be the dilutest, because tension force is bigger；Also can be under triangle pull bar Foot is set as Padfoot and increases pulling force.Specifically how far set pull bar and increase slide resistant pile and turnover stake, the designing technique people in this field Member deals with on the merits of each case；The top terrace of triangular draw bar should use prismatic, and when reducing backfill earthwork sedimentation, pull bar sky is in the face of sedimentation local products Raw top power, impact sedimentation；The recessed slip reducing embankment and the tension force also exploding into the recessed injustice in hole is pulled at smooth steep stone.

4, this anti-skidding retaining wall without base plate can free settling, do not limited by base plate；More will not overall come down.

5, accompanying drawing explanation: accompanying drawing is the fragment of a hypothesis " joint expects anti-skidding retaining wall ".Wherein: 1 is the horizontal stroke of retaining wall Section；2 is triangle pull bar；3 is the slide resistant pile under retaining wall；4 is the pedestal pile of turnover；5 osculums；6 is anti-skid bolt；7 are Retaining wall plate inner face.
