The specific embodiment
In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.
Like a kind of arched retaining wall that Fig. 1-3 relates to for the utility model, it comprises bottom girder 1, column 2 and arched girder 3, and this bottom girder 1, column 2 and arched girder 3 include several and equal prefabricated units for being made up of reinforced concrete structure; Wherein:
Said bottom girder 1, it is rectangular structure, and each bottom girder 1 is parallel to each other and is horizontally embedded equally spacedly horizontal foundation 4 places in side slope, like Fig. 2 and shown in Figure 3, the upper surface of the bottom girder of burying underground 1 and the surperficial flush of ground 4; The upper surface of said each bottom girder 1 all offers a locating slot 11, and this locating slot 11 is strip, and its length direction along bottom girder 1 extends, and the bottom of dimensional structure and following column 2 is complementary;
Said each column 2, as shown in Figure 2, its bottom is adaptive respectively to be positioned in said each locating slot 11, then column 2 upright being located on the bottom girder 1; Column 2 is up-narrow and down-wide right-angled trapezium shape along the vertical cross-section of the length direction of said bottom girder 1; On the side of the pairing column 2 of the right-angle side of its vertical direction, offer a strip groove 21 along this right-angle side extension, then this each strip groove 21 is positioned at the same on the side of column 2;
Said arched girder 3 is arch, and its cross section is rectangular or square, and the two ends of each arched girder 3 all are installed in the two adjacent strip grooves 21, and each arched girder 3 that is positioned at 21 of these same adjacent two strip grooves is up and down, and stack is provided with (as shown in Figure 3).
When this novel arched retaining wall was specifically constructed, its step was following:
1) at first in smooth place, side slope slope angle place, excavation cuboid groove on ground 4, its size is more bigger than the size of bottom girder 1, the bottom compacting;
2) the crane bottom girder 1 of slinging, its groove 11 up, in the ground groove of excavation, hole is with the soil body filling and the compacting of excavation around the bottom girder 1 with bottom girder 1 placing flat;
3) the crane column 2 of slinging, its bottom is put in the groove 11 of bottom girder 1, and groove 11 holes partly inject cement mortar and radially solidify the location;
4) identical method is at the slope angle place that equals arched girder 3 length from bottom girder 1, and excavation ground groove, placement bottom girder 1 and column 2 inject cement mortar, and the strip groove 21 on said each column 2 is positioned at the same side;
5) arched girder 3 is sling, its both ends are stuck in the strip groove 21 of two adjacent upright posts 2, and the lower end (concordant with ground) of taking advantage of a situation down and sliding into strip groove 21;
6) with the adjacent column 2 of quadrat method construction, bottom girder 1 and arched girder 3, after an end of adjacent two arched girders 3 was stuck in the strip groove 21 of same column 2 jointly, the hole of strip groove 21 partly injected cement mortar and solidifies the location;
7) superpose arched girder 3 successively until the required design height of retaining wall with quadrat method, simply accomplish the build of this novel arched retaining wall thus.
According to the novel arched retaining wall of basis that above-mentioned construction sequence is built, it has following advantages:
(1) props up in the retaining; The soil pressure of slope soil horizontal direction acts on the back side of said arched girder 3; It makes full use of the loading characteristic of arched girder 3; Convert horizontal earth pressure into internal pressure, promptly bear the horizontal earth pressure effect by arched girder 3 inside, it can bear bigger horizontal earth pressure than rectilinear common beam; Bearing under the same pressure condition, the sectional dimension that this novel arch design is compared common beam is little, so also have the advantage of economical with materials;
(2) the suffered soil pressure in said arched girder 3 two ends; It is passed on the bottom girder 1 via column 2; It is equivalent to the horizontal force that semi girder opposing column 2 transmits; The pressure that final bottom girder 1 is born acts on the foundation soil after disperseing, and a preferable retaining protective effect is played in effectively decomposition pressure effect thus;
(3) after construction is built, can lay level board at the top of arched girder 3 and column 2, form a hemi-closure space in the bottom of this level board thus, it is used that it can do stored article;
(4) this novel each material that adopts is prefabricate member, and on-the-spot smooth place, crane lifting and the injection small amount of cement mortar of only needing gets final product.
In sum, this its reasonable in design of novel arched retaining wall has advantages such as simple structure, speed of application is fast and have good stability, applicable to the supporting of side slope engineerings such as dykes and dams, riverbank, highway and railway.
Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
