Definitions

  • the present invention relates to an apparatus for excavating an underdrain for draining water from the ground of a highly damp area such as a rice paddy and/or for retaining water in a dry land.
  • An underdrain excavation apparatus has a vertically held soil cutting shank and an underdrain borer having a bullet form provided on a lower end of the soil cutting shank.
  • the apparatus is attached to a rear part of a work vehicle such as a bulldozer or tractor.
  • the work vehicle is advanced in the state where the underdrain borer is arranged at a low position and the lower half of the soil cutting shank is inserted in the ground so that the soil cutting shank is pulled in a horizontal direction to excavate an underdrain in the ground.
  • a perforated pipe for supplying/draining water is sometimes laid.
  • some methods have been proposed: a method in which the distal end of a perforated pipe is coupled with the rear part of an underdrain borer and the perforated pipe is drawn from a perforated pipe supplying device arranged at the starting point of the excavation into an underdrain by the advance of an underdrain excavation apparatus to lay the perforated pipe; a method in which a plastic sheet is embedded in an underdrain while the sheet is being formed circularly by a molding machine; a method in which a hydrophobic material such as rice husks is filled while an underdrain is being excavated; a method in which a pipe is laid and a hydrophobic material is filled while an underdrain is being bored, and the like.
  • underdrain excavation apparatus disclosed in Unexamined Japanese Patent Application No. Sho 56-156310 as an apparatus employed in underdrain construction as described above.
  • this type of underdrain excavation apparatus it is possible that a pipe for supplying/draining water is laid while an underdrain is being excavated in the earth and, simultaneously, a hydrophobic material is filled in the space between the underdrain and the pipe.
  • rice husks filled in an underdrain as a hydrophobic material are stored in a hopper so as to be fed out continuously from the hopper by a feeding device with the progress of underdrain excavation and to be merely dropped into an underdrain via a predetermined transport line.
  • rice husks are not always supplied to the underdrain continuously, and are likely to clog the transport line or to be interrupted. Therefore, rice husks are sometimes not completely filled in an underdrain, thereby causing uneven filling, voids or the like.
  • the film to be buried for this purpose should be of large dimension and high strength, and the film should durable and resistant to sunlight. Furthermore, the film must also be resistant to microbial decomposition in the ground. However, to lay films over a large area is difficult work, and thus far no equipment exists to resolve this problem.

  • the functional material can be transported riding on the gas flow generated by the gas flow generator, the supply/drain pipe can be laid while an underdrain is being excavated in the ground, and filling of the functional material into the space between the underdrain and the supply/drain pipe can be executed in a smooth and reliable manner.
  • the gas flow generator by employing a Coanda spiral flow generator slantingly jetting the high-pressure gas supplied from the high-pressure gas generator from an inner peripheral surface of the tubular body toward the central axis of the tubular body to generate a spiral gas flow along the inner peripheral surface, a special spiral gas flow called the Coanda spiral flow can be generated inside the functional material transport line.
  • the Coanda spiral flow is a spiral gas flow generated along the inner peripheral surface of the tubular body or the like, utilizing the Coanda effect known as a phenomenon that a jet stream of a gas or liquid tends to flow adjacent to a direction along the curved surface of the wall even when the direction of the jet stream axis and the direction of the curved wall are distinct from each other.
  • the functional material By generating the Coanda spiral flow, since suction force is generated in the front part thereof, the functional material can be sucked utilizing the suction force, and the functional material can be transported to an underdrain that is the destination while the functional material is being carried on the Coanda spiral flow flowing inside the functional material transport line.
  • the Coanda spiral flow has a special characteristic of being slightly apart from the inner peripheral surface of the functional material transport line and of flowing while circling along the inner peripheral surface, the contact between the functional material transported by the Coanda spiral flow and the inner peripheral surface of the transport line is eliminated, whereby the functional material can be smoothly transported.
  • the soil pressing members preferably have elevation angles of about 10 to 20 degrees toward the advancing direction, have fins hanging down from the side ends thereof, and are arranged to form a V-shape opening toward the front end when looked in a plan view by the left and right parts thereof.

  • this underdrain excavation apparatus by providing a means for laying a supply/drain pipe in an underdrain simultaneously with excavating the underdrain by moving the traveling device, the supply/drain pipe which effectively drains water to the outside a farmland or supplies water from the outside farmland is simultaneously constructed.

  • water By employing a water-holding material as the functional material, water can be stored in an underdrain constructed in a desert or a dry land, and by appropriately supplying water from outside a farm through the supply/drain pipe, water can be effectively supplied to the ground around the underdrain.
  • the examples of water-holding materials may be processed and decomposed starch-polyacrylonitrile products, starch series such as starch-polyacrylate crosslinking substances, cellulose series such as carboxyl methyl cellulose, and polyacrylate series such as polyacrylic soda crosslinking substance.
  • Water-absorbing polymer is a high polymer electrolyte, in which water molecules are bound in the inter-molecules of three dimensional network structure. While absorbing power of cotton, pulp, sponge, and the like due to capillary phenomenon is about 20 times its own weight, water absorbing polymer can absorb water of about several hundreds to thousands times its own weight.
  • Water absorbing polymer has a large number of hydrophilic groups in molecules, and when there is water, part of it ionizes. Then, cations are isolated in water and start pulling anions remaining in hydrophilic groups, pulling against each other. By this power, molecules of water are captured in hydrophilic groups. Water molecules are firmly held by hydrogen bonding in a fine high molecular network that spreads out in all directions. Since bonding occurs inside the network, water is not disgorged even when the material is pressurized by squeezing. Accordingly, by filling such water-holding material in an underdrain, excellent soil can be obtained without deteriorating gas permeability.
