JPH08280316A - Wall for protecting levee of paddy from being bored by mole - Google Patents

Abstract

PURPOSE: To guide mole holes bored in the levees of a paddy by using protecting walls so as not to form a short-cut way through the levee between an upper paddy and a lower paddy, which is the largest cause of water leakage through the levee, when retaining water in the paddy during the growth term of paddy rice. CONSTITUTION: The protecting walls are buried in the levees to prevent the mole holes from being short-cut between an upper paddy and a lower paddy.

Description

Detailed Description of the Invention

This invention is a protective wall that guides the hole in the paddy field to prevent it from leaking. Many rice fields require great efforts to prevent water leakage damage as water management for paddy fields.
In recent years, fences for preventing water leakage are commercially available, but their effects are insufficient due to the following drawbacks.

[Disadvantages of commercial fences from Rarai]

[Disadvantage 1] During cultivation, the hoe and the rotor of the tractor come into contact with each other, and the fensence is easily damaged. Water leaks due to short circuit between the holes.

[Disadvantage 2] Since the fences of Torai are exposed, there is a risk of injury if you do not pay attention to the work such as mowing grass.

[Characteristics of the product of the present invention] Unlike the method of directly preventing water leakage, this protection wall is used by being buried in a water leakage for the purpose of eliminating the hole that crosses the water leakage causing the water leakage. It should be noted that the shape is a net shape or a band shape, and it is not necessary to stick to the shape of the drawing as long as it has a thickness and strength that is not damaged by a mole nail and a width of about 30 cm.
