Description

Construction method of levee using pre-cast concrete blocks

The present invention relates to a method for forming a rice paddy, and more particularly, by manufacturing the concrete block in a predetermined form in various forms and by installing the concrete block on the rice paddy, it can provide the convenience of farmers and rainy season rice paddy The present invention relates to a rice paddy composition method using precast concrete blocks that can reduce damage.

In general, paddy fields are formed with fresh soil, partitioning between paddy fields, and piled up soil to allow people to travel between paddy fields. The rice paddies formed by soil not only cause a lot of rain or decay when people come and go, but also weeds grow easily, and weeds grow more than necessary, causing problems such as disturbing when people come and go. It's happening.

In addition, in recent years, as rice fields are widened and the length of rice paddies is lengthened according to the clearing of agricultural lands, the rice paddies collapse in the middle, which causes difficulties in managing rice paddies. Therefore, in recent years, there are increasing cases of rice paddy using plastic or concrete, which is more durable and easier to construct than soil.

Plastic prefabricated ricefield according to the prior art is formed in a trapezoidal shape, as shown in Figure 1, the first groove is formed on the outer circumferential surface once, the main body formed with the fitting end (1-2) on the other inner peripheral surface ( It is made up of 1). In order to form the rice field 2 using the main body 1 comprised in this way, first, each main body 1 is lined up in the longitudinal direction, and then in the fitting groove 1-1 formed in the one main body 1; By inserting the fitting end (1-2) formed in the other main body (1), the ricefields (2) could be formed.

In addition, the concrete prefabricated rice field according to the prior art is disclosed in Republic of Korea Utility Model No. 335789 and Public Utility Model No. 1998-10872. The rice paddy block disclosed in Korean Utility Model No. 335789 includes a base buried in the ground and a barrier formed upright from the center thereof, and bolt holes are formed at both ends of the base to connect to the base and the connecting piece of the adjacent block. And a projection is formed on one side of the barrier in the longitudinal direction, while a groove in the longitudinal direction is formed on the opposite side to engage with the protrusion formed on the opposite side of the block disposed adjacent to each other. It is configured to interlock and build rice paddies.

In addition, the paddy field block disclosed in Korean Utility Model Publication No. 1998-10872 is fitted between a fixed support inserted into and fixed to a paddy bottom with a predetermined distance from the paddy bottom. Consisting of the assembly block, the assembly block coupled between the fixed support is formed on each side of the coupling protrusions of the upper and lower strait type, the through hole is formed between each of the coupling projections, the drain hole is formed on one side of the lower body On the other hand, the upper portion of the rectangular pillar-shaped is formed on the upper portion of the fixed support, the reinforcement is formed on the upper portion of the upper body and the coupling grooves are formed in both directions, respectively, the coupling of the assembly block in these coupling grooves The protrusions are fitted so that the ricefields can be installed.

However, the conventional block for constructing the rice paddy has a problem in that it does not provide user convenience. In other words, in rural areas, elderly people in their 60's and 70's are currently farming, and these elderly people have to walk on narrow rice paddies or blocks, causing them to lose their center or to fall off.

In addition, even in the installation of the block, the heavy block is steadily lowered by the load on the plowed rice paddy, so that the height between the blocks is wrong, it is not possible to maintain the level. In the Utility Model Registration No. 335789, a means of tying blocks together using a connecting pin for inter-block connection is used in order to maintain such horizontality. It is self-evident.

The present invention has been made to solve the above-mentioned conventional problems, manufactured to form a large space that can be a foothold of the user on the upper surface of the block to be used as a rice field, the weight chain block is descended by its own weight neighbors The object of the present invention is to provide a method of creating a rice paddy, which is provided with a fall prevention means to prevent the height difference between blocks.

Hereinafter, with reference to the accompanying drawings will be described a method of forming a rice field using a precast concrete block according to a preferred embodiment of the present invention.

The rice paddy composition method according to the present invention is constructed by successively installing a precast cast concrete block between the rice paddies and the discussion as shown in FIG. At this time, the concrete block to be used is a basic block 10 having a cross-sectional shape of the "I" shape, and the T-shaped block 20 having a "T" shape while taking the cross-sectional shape of the basic block 10. And, taking a cross-sectional shape of the basic block 10, having a "b" shaped a-shaped block 30, "L" taking the cross-sectional shape of the basic block 10, although not shown in the embodiment of FIG. Blocks having a magnetic shape and curved blocks are optionally used.

First, as shown in FIG. 3, the basic block 10 is integrally formed with a buried portion 12 and a footrest portion 13 having a wider width than the body 11 at the upper and lower portions of the vertical body 11. . The basic block 10 is precast and manufactured in the factory, and then used to move to the site, the reinforcement is reinforced therein, the lifting ring 16 is integrally combined with the internal reinforcement on the upper surface of the scaffolding portion. Is formed to be exposed. The lifting ring 16 is a means for conveniently used when lifting a block using a crane or a crane to construct a rice paddy, and is preferably formed so as not to protrude from the upper surface of the scaffolding portion 13. That is, when the lifting ring 16 protrudes, it may be convenient at the time of installation, but it may be a problem because it is caught when walking on the footrest 13 after being built.

The basic block 10 has a fitting portion 14 and a fitting groove portion 15 to be fitted to each other continuously at one end and the other end thereof. In addition, the lower portion of the basic block 10 is formed in the center portion on the lower surface recessed recessed recess 17 to pass in the longitudinal direction of the block.

On the other hand, the paddy field is required to form a water gate for the supply and drainage of the paddy water, any one of the basic block 10 may be formed as shown in FIG. In order to form the water gate, a rectangular opening and closing hole 18 is formed from the upper portion to the middle of the central portion of the basic block 10, and a blocking plate (not shown) to be used as a water gate is formed inside the opening and closing hole 18. A guide 19 for sliding down is integrally formed.

In addition, since the basic block 10 is made of reinforcing steel and concrete, its weight becomes significant, and thus it can be lowered into the ground by its own weight. Therefore, in the coupling between the basic blocks 10, it is better to move the lowering prevention means 60 to pass through the lowering prevention grooves 17 formed on the lower surface of the buried portion 12 as shown in FIG. Fall prevention means 60 may be used, such as iron bars or pipes.

Next, the T-shaped block 20 is installed at both ends of the paddy field, and as shown in FIG. 6, wider than the body 11 in the upper and lower portions of the vertical body 11 having a “T” shape. A footrest portion 13 and a buried portion 12 having a width are integrally formed. Like the basic block 10, the T-shaped block 20 has a fitting portion 14 and a fitting groove portion 15 to be coupled with the basic block 10, the lifting ring 16 is formed, The lowering prevention groove 17 is formed on the lower surface to prevent the falling.

Next, the a-shaped block 30 is installed at both ends of the rice paddy, and if the T-shaped block 20 is at the boundary with the neighboring rice paddies, the a-shaped block 30 serves as a discussion out corner. As shown in FIG. 7, the a-shaped block 30 has a footrest portion 13 and a buried portion 12 formed on the upper and lower portions of the vertical body 11, like the basic block 10, and the fitting portion 14. ) And the fitting groove 15 is integrally formed, the lifting ring 16 is formed, the falling prevention groove 17 is formed.

Next, as shown in FIG. 8, the L-shaped block has a scaffolding portion 13 formed on the upper surface of the vertical body 11, similarly to the basic block 10, and the fitting portion 14 and the fitting groove portion 15 are formed. It is formed integrally, the lifting ring 16 is formed, the falling prevention groove 17 is formed. In addition, a water gate may be formed in the L-shaped block 40. This L-shaped block 40 is used in the rice paddy field where the height of the neighboring paddy field is significantly different, as shown in FIG. 9, and only the basic block 10 formed only vertically of the load generated in the upper paddy field is used to hold it. Because it can not be used to form the letter "L" to be embedded deep into the bottom of the upper rice field. Therefore, the L-shaped block 40 is a block that becomes the dam itself, like the basic block 10, unlike the T-shaped block 20 or a-shaped block (30). And since the lower portion of the L-shaped block 40 is buried underground, it is not necessary to form a separate buried portion like other blocks.

On the other hand, there are many places where rice paddies are still winding and not winding in rice fields that have not been arranged. The block for constructing the meandering paddy field is a curved block 50 as shown in FIG. The curved block 50 has only the difference between the basic block 10 and the straight form or the curved form, the shape and structure are all the same. Therefore, the curved block 50 may be formed in the body, buried portion, scaffolding, fitting, fitting groove, lifting ring, sluice, falling prevention groove.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined by the appended claims. .
