JPS6059218A - Concrete footpath for rice paddy field - Google Patents

Abstract

PURPOSE:To increase the area of a paddy field as well as reduce the consumption of labor by a method in which a footpath of a trapezoidal or rectangular form in cross section is formed by providing a water channel of synthetic resin pipe inside and also providing an outlet in the water channel. CONSTITUTION:A water channel 1 of synthetic resin pipe is provided in a pathway for a concrete footpath. Water outlets 2 are provided in adequate places of the water channel 1, and U-shaped projected walls 3 or U-shaped grooves 4 are provided on both ends. The area of the paddy field can thus be increased, the consumption of labor can be reduced, and damage by field rats or vermin can be prevented.

Description

[Detailed description of the invention] The present invention relates to a rice field road.

In the past, the rice fields themselves differed in shape depending on the high bottom of the ground and the shape of the surrounding area, and therefore the banks were irregular, but recently, this has completely changed due to ground clearance projects, and large rice fields have been formed. As a result, the roads along the banks were completely changed and made straighter, making it possible to use large machines for work, and the area of each paddy field became larger.
It is becoming a big agricultural industry. However, the road along the road remains the same as before and has not been improved.

In the early spring of every year, the surface of the rice paddies is scraped off, and before rice planting, the scraped area is covered with mud using a hoe, and the soil is carefully smoothed down using force.Nowadays, each work has been mechanized. This has become the most difficult work for farmers. The grass needs to be mowed 23 times a year, and it becomes a nest for field mice and pests, and it also acts as a reservoir for disease germs. This is something that definitely needs improvement.

This proposal was proposed as the best method for the reasons mentioned above. As the area expands, the roads along the banks have also been extended, making it difficult to carry out field work in the fields due to the softness of the land. Therefore, it would be a good idea to manufacture the appropriate length in a factory, transport it, and extend the connection. This project was conceived and designed with that purpose in mind. In the cross section of Fig. 2 and Fig. 3, embed a pipe (1) with a diameter of about 9 to 10 cm between the concrete blocks with a height of 25 cm inside and outside, and a top end of 20 cm inside and outside, keeping the Camry 3 cm inside and outside. Attach a twig pipe (2) with an internal connection downwards to the outer surface of the concrete. (Figs. 4, 5, and 6) Regarding the connection surface of the block, there are U-shaped protrusions as shown in (3) in Figs. 7, 8, and 9, and as shown in Figs. A U-shaped groove (4) is provided in the same shape and size as the protrusion.

With the above configuration, it can be freely connected and extended depending on the location and used as a passage and waterway. Make sure the connections fit well. In addition, if you insert pipes with the same outside diameter as the inside diameter of pipe (1) by 10 cm each, you will be able to create a strong and beautiful passage without any misalignment on each side.The upper corners should of course be chamfered.

The effects of the present invention were explained in the objective section, but they will be summarized below.

B. The area of rice fields is increasing (used amount) (b) Labor is greatly reduced.

Ha, damage from field mice and pests will be reduced.

D. The troublesome hanging of water is shortened. (In the case of a long water passage, attach two or three small pipes (2) and open them.) E. The block is heated, so the water inside the water passage is heated. The water is heated and the hot water supply is effective for the growth of rice.
