Description

Retaining Wall for Embankment {REVETMENT FOR A BANK}

The present invention relates to a retaining wall used in embankments, freshwater structures, and the like, wherein the retaining wall is composed of members loaded on each other and made of concrete or similar material. These members are approximately prismatic in the height direction, and each member has two transverse and two longitudinal sides between the top and bottom surfaces, and the retaining wall extends between the top and bottom surfaces and allows water to pass through. Has an open space.

Such retaining walls are disclosed in Dutch patent C-122279. This known retaining wall is made of the same member of polygonal convex shape. The retaining wall provided with the open space is manufactured by such a shape, and the retaining wall has an advantage that no buoyancy occurs under the retaining wall. This design is very advantageous for sloped retaining walls such as coastal banks and river banks. Even if water continues to flow toward the slope through the open space in the form of waves, the water can flow out again without being disturbed, so that the member is not swept away, so that the retaining wall is not damaged.

However, a disadvantage of this conventional retaining wall is that an advantageous ratio of open space to closed space exists only in the straight portion of the slope. In the case where the slope is a bent portion, a larger open space is left open because the known members no longer mesh well with each other. Of course, such larger open spaces may be reduced by skilled relocation or by filling with smaller pieces, but such work requires skilled technicians and is not always possible.

1 is a perspective view of a concrete member according to the present invention,

FIG. 2 is a view showing a first arrangement in which the member according to FIG. 1 is disposed in a straight path;

3 is a view showing a second arrangement form,

4 is a diagram showing the arrangement form arranged in a curved path.

It is an object of the present invention to provide a retaining wall which can be easily arranged using a machine and an unskilled technician, and at the same time, the ratio of the open part to the closed part is accurate even at the curved part of the slope. This object is achieved by making one of the transverse faces of each member into a concave shape and the other of the transverse faces into a corresponding convex shape.

The concave / convex shape of the members allows the members to be stacked so that they engage well with each other even at curved portions of the slopes. Moreover, this advantageous result can be achieved in various gradients, and the breakwater wall can also be sheathed with a member according to the invention. Due to the presence of open spaces, water cannot have any effect on the retaining wall.

The members form a row, with the transverse sides of each row being supported relative to each other, and the members of adjacent rows being supported by their longitudinal sides relative to each other.

The retaining wall disclosed in Dutch Patent No. C-1222709 is made of members having transverse and / or longitudinal sides formed such that the members stacked on each other allow water to pass through with an empty open space. In the case of the retaining wall according to the present invention, in addition to the concave / convex shape, a member shape according to Dutch Patent No. C-122279 which provides an open space may be used.

However, in the case of the retaining wall according to the invention, it is advantageous that at least one of the transverse and / or longitudinal side comprises a passage opening, wherein the transverse and / or longitudinal side bear against each other at various rotational positions of the transverse side. The members can be loaded in a losing state while the members stacked relative to each other are formed so that there is an open space through which water can pass, the passage openings each being opened with passage openings and / or opposing walls of adjacent members. Form a space.

As a variant, the member may comprise a passage opening that is not open in the transverse or longitudinal side.

In particular, the transverse side surfaces of the members can be parallel in the height direction and have a corresponding round shape, advantageously corresponding to a part of the cylindrical body. The longitudinal side of the member is basically flat and can be loaded with a half-brick bond or a brick bond. In this case, the members form a row, and the transverse sides of each row are supported with respect to each other.

In order to form the necessary openings, recesses may be provided in one or more of the longitudinal sides or in the transverse sides.

The invention also relates to a member for use in a retaining wall according to the invention.

Hereinafter, the present invention will be described in more detail with reference to the embodiments illustrated in the drawings.

Concrete members used in embankment retaining walls, freshwater structures, etc., are generally indicated by reference numeral 1, which includes a bottom face 2 (not shown), an upper face 3 and a circumference of a prismatic mold indicated by reference numeral 4 as a whole. .

The perimeter consists of two longitudinal sides 5, 6 (where 5 is not visible) and two transverse sides (7, 8; 7 is not visible).

The circumference 4 is slightly inclined and narrows slightly toward the upper surface 3.

Each longitudinal side 5, 6 essentially has a square 9 recess. The rear transverse face 7 of each member is concave and the front transverse face 8 is convex. Both the concave surface 7 and the convex surface 8 correspond approximately to part of the cylindrical body. The convex surface 8 also has a substantially rectangular concave portion 10.

As shown in Figures 2 and 3, the concrete member according to the present invention can be used for the retaining wall in various forms. In FIG. 2, the concrete member 1 is mounted so that the longitudinal side surfaces 5 and 6 may fully support each other. In this case, the recess 9 of the transverse side forms an opening, while the recess 10 of the front convex transverse side 8 also forms an opening. In addition, an opening 11 is formed between the four concrete members 1.

Such recesses can also be found in the case of the half-brick pattern of FIG. 3. The purpose of this recess is to allow water to flow through the retaining wall by the action of waves and to easily flow back through the retaining wall. This ensures that excessive pressure under the retaining wall is prevented from being swept away or causing erosion under the member.

According to the invention, the concave transverse surface 7 and the convex surface 8 are fitted to each other at various angular positions, as is apparent from FIG. 4. Since the members are sequentially stacked in various rows 12, their transverse side surfaces 7 and 8 are in intimate contact with each other irrespective of their angular positions.
