Abstract

PURPOSE: A construction method of a riverbank block retaining wall is provided to have excellent binding force and strength of a retaining wall and to heighten economical efficiency by utilizing soil and stone or gravel. CONSTITUTION: The construction method of a riverbank block retaining wall comprises the steps of placing an eye-tooth stone(2) on a footing stone(1), erecting a wire mesh(4) and a plaster board form(5) on the back at regular intervals, forming a cement mortar layer(3) and filling up a rubble layer(6), then building the next stage in order.

Description

Construction method of riverbank retaining wall {Method of Constructing Blocks for Riverside Bank}

The present invention relates to a method for building a bottom block retaining wall for preventing collapse and flooding of a riverbank. The retaining wall installed on the bottom is divided into the traditional concrete retaining wall and the block retaining wall. The former is solid but the installation cost is not only excessive but also the appearance is rough, while the latter is not as strong as the former but the installation cost is cheaper and the appearance is beautiful and the environment Friendly. Therefore, in recent years, block retaining walls are preferred unless they are special cases.

In the case of a block retaining wall, there is an anchor block made of cement, which is generally fixed by inserting geosynthetic fibers between anchor blocks and fixing the rear soil section.

The present invention is a method of building a cement mortar and a back ground rubble layer with the same height on the back while stacking the cantilever masonry, one by one, by using a natural stone instead of a cement anchor block. It is an improvement.

According to the present invention, in the block retaining wall constructed of the scapula, the boundary of the back stool rubble is not clear on the back of the scapula so that the thickness of the cement mortar layer which fixes the scapula and determines the strength of the retaining wall becomes uneven and thus collapses by flooding. It is trying to solve the problem.

<Description of Symbols in Drawings>

1: foundation stone

3: mortar layer 4: wire mesh

5: Formwork 6: Rubble layer

7: rear soil section

The method of the present invention will be described in detail with reference to the drawings.

Place one stage of scabbard (2) on the foundation stone (1), set up one stage of wire mesh (4) and gypsum board formwork (5) at regular intervals on the back, and form a cement mortar layer (3). (6) is replaced and the next step is constructed in the same way.

The wire mesh 4 and the gypsum board formwork 5 have a height comparable to that of the unit tartar 2 and are installed in the same slope as the inclination angle of the cantilever 2. The wire mesh 4 and the gypsum board formwork 5 are combined with common fixing means such as pins or clips to facilitate work. The back of the gypsum board formwork 5 is filled with soil and rubble collected from the bottom.

Although not shown in the drawing, a normal drain pipe penetrates the cement mortar layer 3 and communicates with the rubble layer 6 in the lower portion of the gingiva stone 2.

In the present invention, the cement mortar layer 3 is not only rigid because the wire mesh 4 acts as a core material, but is also partitioned from the rubble layer 6 by the gypsum board formwork 5 to have a certain thickness. As if studded with a stiff stone (2) will be built a solid retaining wall.

In particular, the conventional cantilever retaining wall is fragile because the cement mortar layer 3 is not drained smoothly or there is a risk of collapse if the load of the back litter rubble is applied. Forming the layer (6), because the granulated gravel must be purchased at a high price, greatly increases the construction cost.

In the construction method of the present invention, since the cement mortar layer 3 has a certain thickness and is firm with the reinforcing force of the wire mesh 4, the back rubble rubble layer has soils that are easily sieved from the bottom, such as concrete retaining walls, instead of a crushed gravel of a certain particle size. It is economical because it can be filled with gravel.
