Description

Novel retaining wall

Technical Field

The utility model relates to the technical field of buildings, in particular to a novel retaining wall.

Background

The unloading type retaining wall is a retaining structure which is provided with an unloading platform or an unloading plate on the wall back to reduce the soil pressure of the wall back and increase the stable moment so as to resist the lateral pressure of the soil body together by the filled soil weight and the self weight of the wall body. However, when the wall body is high or the excavation of wall back soil is limited, the lower part of the wall body is still greatly stressed due to the limited action of the unloading plate, and the performance of the retaining wall is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a novel retaining wall to solve the technical problems in the prior art.

In order to solve the technical problem, the novel retaining wall provided by the utility model comprises a wall body; the back of the wall body is provided with an unloading plate and a counterfort; the unloading plate is higher than the buttress; the plurality of buttresses are sequentially arranged at intervals along the length direction of the wall body.

Furthermore, the position where the bottom surface of the unloading plate is connected with the wall back is provided with an armpit.

Further, the unloading plate is positioned at seven tenths of the height of the wall body.

Further, the length of the unloading plate is 1-3m, and the thickness of the unloading plate is 350-400 mm; the thickness of the wall body is 400 mm.

Furthermore, the unloading plate is made of reinforced concrete.

Further, the buttress is in a right-angled triangle shape.

By adopting the technical scheme, the utility model has the following beneficial effects:

according to the novel retaining wall provided by the utility model, the unloading plate is arranged at the proper height of the wall back, so that the effects of reducing the soil pressure of the wall back and increasing the stable moment are achieved, meanwhile, the counterfort is arranged at a certain distance in the length direction of the wall body, the stress condition of the wall panel and the wall heel plate can be improved, the rigidity and the integrity of the structure are improved, and the deformation of the wall panel is reduced. The unloading plate divides the wall into an upper part and a lower part, and because of the existence of the unloading plate, the stress of the lower part is greatly reduced. When the wall body is higher or the excavation of the back soil of the wall back wall is limited, the stress of the lower part is still very large due to the limited effect of the unloading plate, the stress mode of the lower part can be improved by arranging the counterfort, and compared with the unloading plate type retaining wall or the counterfort type retaining wall, the height of the wall body applicable to the utility model is higher, the engineering investment is saved by 10-20 percent, and the higher the height is, the higher the benefit is.

The utility model simultaneously considers the advantages of the unloading plate type retaining wall and the counterfort type retaining wall, and is suitable for the situation that the height of the retaining wall is higher (for example, H is more than or equal to 10 meters) or the excavation of wall back soil is limited. Meanwhile, the stress of the whole retaining wall can be improved by adjusting the position (height and length) of the unloading plate and the position (height and spacing) of the counterfort, so that the novel retaining wall provided by the utility model has a larger application range and is less influenced by the surrounding conditions.

The present invention will be further explained with reference to specific embodiments.

As shown in fig. 1-2, the novel retaining wall provided by the present embodiment includes a wall body 1; the back of the wall body 1 is provided with an unloading plate 2 and a counterfort 3; the unloading plate 2 is higher than the buttress 3; a plurality of buttresses 3 are arranged at intervals in sequence along the length direction of the wall body 1.

The novel retaining wall that this embodiment provided sets up off-load board 2 in the suitable high department of the back of the wall, reaches the effect that reduces back of the wall soil pressure and increase steady moment, sets up counterfort 3 at 1 length direction at every interval of wall body simultaneously, can improve the atress condition of shingle nail and wall heel board, improves the rigidity and the wholeness of structure, reduces shingle nail's deformation. The unloading plate 2 divides the wall body 1 into an upper part and a lower part, and because of the existence of the unloading plate 2, the stress at the lower part is greatly reduced. When the wall body 1 is higher or the excavation of the back soil of the wall back wall is limited, the lower part is still greatly stressed due to the limited effect of the unloading plate 2, the stress mode of the lower part can be improved by arranging the counterfort 3, and compared with the unloading plate 2 type retaining wall or the counterfort 3 type retaining wall, the height of the wall body 1 applicable to the utility model is higher, the engineering investment is saved by 10-20%, and the higher the height is, the higher the achieved benefit is.

The utility model simultaneously considers the advantages of the unloading plate 2 type retaining wall and the counterfort 3 type retaining wall, and is suitable for the situation that the height of the retaining wall is higher (for example, H is more than or equal to 10 meters) or the excavation of wall back soil is limited. Meanwhile, the stress of the whole retaining wall can be improved by adjusting the position (height and length) of the unloading plate 2 and the position (height and spacing) of the buttresses 3, so that the novel retaining wall used by the utility model has a larger application range and is less influenced by the surrounding conditions.

On the basis of the above embodiment, furthermore, the position where the bottom surface of the unloading plate 2 is connected with the wall back is provided with an armpit 4.

On the basis of the above embodiment, further, the unloading plate 2 is located at seven tenth of the height of the wall body 1, that is, the ratio of the height of the retaining wall above the unloading plate 2 to the height below the unloading plate 2 is 3: 7. The length of the unloading plate 2 is 1-3m, the thickness of the unloading plate 2 is 350-400mm, and the thickness of the wall body 1 is 400 mm. The shorter the unloading plate 2 is, the larger the stress of the lower part is, and the lower part stress is reduced along with the increase of the height of the unloading plate 2, so that when the unloading plate 2 is increased to a proper height and the distance between the buttresses 3 is adjusted, the whole retaining wall can reach an optimal section. Experiments prove that when the unloading plate 2 is positioned at seven tenth of the height of the wall body 1, the length of the unloading plate 2 is 1-3m, the thickness of the unloading plate 2 is 350-400mm, and the thickness of the retaining wall is 400mm, the best effect is achieved.

Preferably, the unloading plate 2 is made of reinforced concrete.

Buttress 3 is preferably in the form of a right triangle.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
