The utility model provides stake holder counterfort retaining wall structure, place the outside of the side slope of banketing, comprise the pile foundation that places foundation soil and upper end to extend the described side slope surface that bankets, connect described pile foundation upper end bearing sheet, be vertical and place described bearing sheet upper end and be attached at the facade plate of the described side slope lateral surface that bankets and place described bearing sheet upper end and be attached at the counterfort of described facade plate inner surface.
In the utility model, utilize pile foundation, can overcome the problem of foundation soil Lack of support, the height scope of application of facade plate and counterfort is larger, and can firmly place on the side slope lateral surface that bankets, thereby the side slope of banketing is played preferably support action.
Below in conjunction with concrete accompanying drawing realization of the present utility model is described in detail.
Shown in 1 ~ 4, a preferred embodiment that provides for the utility model.
The stake holder counterfort retaining wall structure 1 that present embodiment provides is located at side slope 2 outsides of banketing, and is used for the supporting side slope 2 of banketing, and the side slope 2 of banketing is played an effect of gear.
The retaining wall structure 1 that present embodiment provides comprises pile foundation 11, bearing sheet 12, place the facade plate 13 on the bearing sheet 12 and the counterfort 14 on these facade plate 13 inner surfaces of being sticked.This pile foundation 11 places foundation soil 21, and extend outside the foundation soil 21 its upper end; Facade plate 13 is the vertical upper end that is arranged on bearing sheet 12, and inner surface is attached to the outside of the side slope 2 of banketing; 14 of counterforts are sticked on the inner surface of facade plate 13.
Utilize above-mentioned retaining wall structure 1, pile foundation 11 can be arranged in the foundation soil 21, thereby go for soft layer, its pile foundation 11 can directly penetrate soft layer, stretch into soil layer firm under the ground, thereby can solve the problem of natural ground soil layer or filled ground soil layer Lack of support; The facade plate 13 that arranges on bearing sheet 12 upper ends and counterfort 14 adopt the buttress type structure, and required height can be set according to actual needs, thereby so that retaining wall structure 1 maxi-mum height is larger, and with respect to gravity retaining wall, structure 1 has been saved quantity of masonry, with respect to cantilever retaining wall, more can control the distortion at top, quality is in controllable state, so that the support action of retaining wall structure 1 can be not influenced.
Pile foundation 11 in above-mentioned comprises front campshed 111 and the rear campshed 112 that is set up in parallel, front campshed 111 is provided with the bearing sheet 12 that extends outside the foundation soil 21 with the upper end of rear campshed 112, this bearing sheet 12 is connected to the upper end of front campshed 111 and rear campshed 112, and is connected to the lower end of facade plate 13 and counterfort 14.Like this, by bearing sheet 12, so that facade plate 13 and counterfort 14 are connected to overall structure with pile foundation 11 respectively, thereby strengthen the anti-overturning of whole retaining wall structure 1; And the pile foundation in the present embodiment 11 is for Double-row-piles Structure designs, and it can make the overturning or slip resistance analysis moment of retaining wall structure 1 increase, and greatly strengthens the anti-overturning of this retaining wall structure 1.
In the practice of construction process, front campshed 111 and the rear campshed 112 of pile foundation 11 can be extended respectively foundation soil 21 outer certain distances, certainly, the size of distance can be decided as required, thereby increases the maxi-mum height of this retaining wall structure 1.
In the present embodiment, pile foundation 11 adopts the Double-row-piles Structure design, and especially rear campshed 112 has the effect of uplift pile, strengthens the anti-overturning of whole retaining wall structure 1.
Certainly, the front campshed 111 in above-mentioned and rear campshed 112 are respectively arranged with a plurality of, and these a plurality of front campsheds 111 arrange sequentially that along side slope 2 outsides of banketing certainly, a plurality of rear campsheds 112 are also sequentially arranged along side slope 2 outsides of banketing.Certainly, should guarantee certain distance between front campshed 111 and the rear campshed 112, the size of actual range should be determined according to the stressed size of stake.Certainly, what front campshed 111 and rear campshed 112 also can be according to actual loading size, roles is different, adopts different pile spacings.
For so that be connected firmly between facade plate 13 and counterfort 14 and the pile foundation 11, be provided with bearing sheet 12 between pile foundation 11 and facade plate 13 and the counterfort 14, the lower end of this bearing sheet 12 is connected on front campshed 111 and the rear campshed 112, and its upper end then is connected to facade plate 13 and counterfort 14.And, for the cutting-bearing capacity that guarantees bearing sheet 12 meets the demands, the thickness of bearing sheet 12 should pass through calculative determination, and in pile foundation 11 and bearing sheet 12 connected node positions, by vertically, laterally all disposing the cutting-bearing capacity that improves bearing sheet 12 perpendicular to the Punching Shear stirrup 17 of the punching failure conical surface 16.
Above-mentioned facade plate 13 is formed in one with counterfort 14, and bearing sheet 12 is the state of being arranged vertically with facade plate 13, certainly, also can be the step-by-step construction moulding, and concrete moulding is decided by the practice of construction situation.
In the present embodiment, counterfort 14 according to related specifications and stressed size according to a determining deviation setting.Simultaneously, in order to give full play to the vertical bearing capacity of pile foundation 11, should make counterfort 14 before and after the projection on the bearing sheet is positioned on two piles 111,112 the stake position center line.
Certainly, for so that the water in the side slope 2 of banketing of retaining wall structure 1 inboard can excrete outside the retaining wall structure 1, the panel of this retaining wall structure 1 is provided with spilled water hole 15, one end of this spilled water hole 15 connects side slope 2 inside of banketing, its other end connects outside the retaining wall structure 1, thereby, so that the water in the side slope 2 of banketing can excrete via this spilled water hole 15.
Along the direction that the side slope 2 of banketing is extended to retaining wall structure 1, the spilled water hole in above-mentioned is obliquely installed down, thereby the water in the side slope 2 of being more convenient for banketing excretes via this spilled water hole 15.
In the practice of construction process, the construction sequence of above-mentioned retaining wall structure 1 is as follows:
1), on original ground 21 smooth location, for operation platform is reserved in the construction of pile foundation 11;
2), in foundation soil 21 construction stake basis 11 so that extend outside the foundation soil upper end of pile foundation 11;
3), construction bearing platform plate 12 on pile foundation 11;
4), at bearing sheet construction facade plate 13 and counterfort 14;
5), the construction spilled water hole 15 so that spilled water hole 15 passes facade plate 13;
6), the backfill soil body 22, the layering spreading is closely knit pushes up to retaining wall.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
