Description

[Detailed description of the invention] <Industrial field of application> The present invention relates to a concrete block for stacking stones used for retaining work, earth retaining work, etc.

<Prior art> In the case of construction and earth retention work, there are cases where the earth retention and earth retention are formed using concrete walls, and cases where the earth retention and earth retention are formed by piling up concrete blocks. If the length is long, the retainers and retainers are usually made of concrete blocks for masonry.

By the way, a considerable amount of water-containing earth pressure is applied to the horome and tsurume, but in order to form the horome and tsurim to withstand this earth pressure, it is necessary to have multiple drainage holes that penetrate from the back side to the front side of the horome and tsurume. It is necessary to drill a hole.

Conventionally, this drainage hole was formed by crushing the end of a concrete block for masonry, forming an insertion hole for the drainage hole pipe, and inserting the drainage hole pipe into this insertion hole, as shown in Fig. 1. The surrounding area was filled with mortar and the exterior was finished, creating multiple drainage holes.

However, since the concrete blocks used for stacking stones are made of gravel, they break down more than necessary.
As shown in FIG. 1, there was a drawback that the aesthetic appearance was extremely degraded.

Furthermore, this conventional method has the disadvantage that the strength of installing the drain hole pipe is low, requiring unnecessary labor and materials such as crushing the edges of concrete blocks for stacking stones and filling with mortar.

<Purpose of the invention> Thus, the present invention was devised to solve these conventional drawbacks and problems. It also has an excellent aesthetic appearance.
Furthermore, it is an object of the present invention to provide a concrete block for masonry with a drainage hole pipe that does not cause waste of labor or materials.

<Structure of the invention> The concrete block for masonry with a drainage hole pipe according to the invention is a concrete block for masonry for legal retaining and earth retaining, and the concrete block for masonry has a structure from the back side to the front side. A drain hole pipe is buried that penetrates the drain hole pipe with a downward slope, and a reinforcing anchor is attached to the outer periphery of the drain hole pipe, and a reinforcing anchor is attached to the outer periphery of the drain hole pipe, and a reinforcing anchor is inserted from the reinforcing anchor to penetrate into the inside of the drain hole pipe. , is constructed by extending a blocking rod capable of blocking gravel from passing through the drain hole pipe.

<Example> The present invention will be described below based on an example shown in the drawings.

Figures 3 and 4 are cross-sectional views showing a concrete block A for masonry with drain holes according to the present invention. FIG. 3 shows a concrete block A for a 3-minute slope, and FIG. 4 shows a concrete block A for a 5-minute slope.

Concrete block for masonry with drainage hole pipe A
is used for horome, earth retaining, etc.

By the way, this concrete block A for stacking stones
A drain hole pipe 1 is buried in the drain hole pipe 1. However, the outline of the drain hole pipe 1 is shown in FIG.
This drain hole pipe 1 is formed of a vinyl pipe or the like. The length thereof is defined as the length extending from the front surface to the back surface of the concrete block A for stacking stones.

By the way, the reference numeral 2 indicates a reinforcing anchor. The reinforcing anchors 2 include a plurality of approximately ring-shaped anchor bars 3 provided on the outer periphery of the drain hole pipe 1 at slight intervals and in the longitudinal direction of the drain hole pipe 1.
It is configured to include connecting bars 4 that connect the plurality of anchor bars 3....

Furthermore, blocking rods 5 are attached to the plurality of anchor bars 3, which pass through the inside of the drainage hole pipe 1 and can block gravel, etc., which pass through the drainage hole pipe 1 and are discharged to the outside. There is.

By the way, this drain hole pipe 1 is installed in advance in the formwork when the concrete block A for stacking stones is formed, and once the concrete block A for stacking stones is formed, it will be buried and fixed inside. .

As mentioned above, Fig. 3 shows a concrete block A for masonry with a drainage hole pipe on a 3-minute slope, and Fig. 4 shows a concrete block A for masonry with a drainage hole pipe on a 5-minute slope. It is shown. However, regardless of the slope, it is important to bury and fix the drain hole pipe 1 so that the water flow gradient of the drain hole pipe 1 slopes downward from the back side of the stone block A to the front side. be.

<Effects of the invention> Thus, the present invention consists of the above configuration. The concrete blocks for masonry with drainage hole pipes according to the present invention can provide retaining and earth retaining blocks with superior aesthetic appearance compared to the conventional concrete block for masonry as shown in Fig. 1. This provides excellent effects such as the installation strength of the pipe is high, and furthermore, there is no need for labor and materials for retrofitting the drain hole pipe.
