Abstract
The invention discloses a combined balance weight retaining wall, which is applied to various balance weight retaining walls, in particular suitable for a balance weight retaining wall under hillside topographic conditions. The retaining wall comprises a lower wall body and an upper wall body, wherein the height ratio of the lower wall body to the upper wall body is (2-3):1; and the upper wall body consists of a bottom plate which serves as a weighing table and a vertical plate which is connected with the bottom plate. According to the combined retaining wall, the soil pressure is converted into soil pressure and friction force borne by upper reinforced concrete, and the safety and applicability of the retaining wall are greatly improved; and moreover, compared with the traditional pitching inclined mode, the vertical wall back has the advantage of low soil pressure, the section area is greatly reduced, and the material is reduced; and therefore, the engineering quantity is reduced, and the engineering construction cost is reduced.
Description
Technical field
The present invention relates to a kind of retaining wall, especially relate to a kind of combined type weight retaining wall.
Background technology
The balance weight retaining wall that the retaining wall many employings slabstone being generally highly greater than 8 meters is at present built by laying bricks or stones or reinforced concrete structure retaining wall.Generally speaking, because balance weight retaining wall the first half soil pressure is larger, therefore be easy to occur the eccentric excessive and phenomenon of tension in weight position of platform, retaining wall the first half wall back of the body generally makes inclined of bowing, add the width of weight platform, so general balance weight retaining wall cross section is comparatively large, especially true when wall back of the body load or the wall back of the body have slight slope.
In engineering design, balance weight retaining wall uses a lot at present, and it can save constructional materials more than 20% ~ 30% than simple gravity retaining wall, and can obtain more uniform foundation stress.The balance weight retaining wall that the retaining wall that Present Attitude is greater than 8 meters generally adopts slabstone to build by laying bricks or stones more or reinforced concrete structure retaining wall.But, there is the problem that crack is even destroyed in the eccentric excessive and tension of existing balance weight retaining wall weight platform place ubiquity.And owing to limiting by cross section, thus affect the increase of wall height.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art, for retaining wall overall height more than 8 meters or higher when, a kind of new retaining wall structure is provided.
In order to achieve the above object, technical scheme provided by the invention is:
Described combined type weight retaining wall comprises lower wall body 1 and upper wall body 2; Lower wall body 1 is 2 ~ 3:1 with the aspect ratio of upper wall body 2; Described upper wall body 2 is made up of the base plate 3 as weight platform and the riser 4 that is connected with base plate 3; Angle α≤90 ° of described riser 4 and base plate 3; The gradient of described lower wall body metope 5 is 1:0.05 ~ 0.25.
Wherein, described lower wall body 1 material is mortar flag stone or rubble concrete, is preferably mortar flag stone; Described upper wall body 2 material is steel concrete or fibrous concrete, is preferably steel concrete.
In addition, can connect in the following ways between the body of wall of top and the bottom:
A, described base plate 3 lower surface face are provided with tenon or groove, and described lower wall body 2 end face is provided with the plug-connection structure corresponding with base plate 3 bottom tongue or groove;
The flange being fastened on lower wall body 2 top is provided with bottom B, described base plate 3;
C, described base plate 3 lower surface and lower wall body 2 end face are Rough Horizontal Plane.
Improving as one, in order to adapt to higher Foot of Upper Retaining Wall height, between described riser 4 and base plate 3, being provided with counterfort 6.
In building operations of the present invention, first on ground, build lower plate stone walling body by laying bricks or stones, then build upper reinforcement concrete structure on the basis of lower wall body.The cross section of steel concrete and slabstone body of wall can have various ways to provide frictional force, or shearing frictional force being transformed into slabstone body of wall is to ensure top and the bottom body of wall co-operation effectively.
Compared with prior art, beneficial effect of the present invention is:
The present invention considers from saving, Foot of Upper Retaining Wall makes wall back of the body vertical type or cantilevered reinforced concrete structure, make full use of the advantage that strength of reinforced concrete tensile property that is high and reinforcing bar is good, less than the soil pressure of bowing in conventional method suffered by inclined, and substantially reduce sectional area, namely reduce sectional area decreases by doses, thus decreases engineering quantity and reduce construction investment, adopts the intensity of reinforced concrete also higher.This knockdown retaining wall advantage soil pressure to be changed into the shear stress or frictional force that upper reinforcement concrete bears, and materially increases safety and the applicability of retaining wall.
For wall body overall height 9.6m, the wall back of the body soil body gradient is 1.5:1, traditionally built retaining wall weight platform place wall body overall width is 3.94m, and to build retaining walls body overall width by the inventive method be 3.06m, total-width ratio conventional method reduces 0.88m, reduce overall width and will reduce earth excavation amount, Economization on land consumption.If add counterfort, the higher height improving whole retaining wall that superstructure can be done in the middle of Foot of Upper Retaining Wall.
This combined type weight retaining wall is particularly suitable for building of hillside area retaining wall.In other occasions, the scheme of the balance weight retaining wall that a kind of occupation of land also can be provided more to save.
