Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underdrain hydrophobic material filling device.

[0002]

2. Description of the Related Art Conventionally, as a construction method of an underdrain, a method of arranging an earth pipe on the bottom of the underdrain is generally used, and this is the first method of filling a hydrophobic material.

[0003]

The problems described in the prior art have the following problems. Conventionally, there is an example in which a wood chip material or the like is filled on the earth pipe at the bottom of the underditch, but all of them rely on manpower. The present invention has been made in view of such problems of the conventional technique, and an object of the present invention is to provide the following:
This is a device to establish the new underdrain method, and is an indispensable device for a farmer to construct a vast field efficiently by one worker. This is the background of the need for the present invention, which will be specifically described below with reference to FIGS.

A. In the conventional underdrain construction method in upland fields and pastures, a V-shaped groove is formed by an excavator (power shovel), and an earth pipe or a vinyl hose is manually installed at the bottom of the V-shaped groove. Since a V-shaped groove is entered by a person for work, the groove width is required to be about 600 m / m to 1000 m / m and the depth is required to be about 900 m / m to 1000 m / m.

B. In the conventional technology,
It had the following problems. a. Since a power shovel (weight: 18 ton) enters the field, the soil is hardened by the trampling pressure and water permeation is deteriorated. b. Soil containing organic matter (topsoil) due to large excavation volume
The replacement of the mineral soil at the bottom with the soil adversely affects the crops. c. The work speed of the power shovel is as low as 80 m / hour. Furthermore, labor and material costs such as clay pipes are required. d. Buried earth pipes are 2 years old due to vibration from tractor work
Cut off the waterway as it will be damaged in about 3 years. In cold climates, freezing causes damage.

C. In order to solve the problems of the conventional technology, the applicant previously proposed the following proposal in Japanese Patent Application No. 10-319.
It went as No. 974. (For convenience of explanation, Japanese Patent Application No. 10-
The code was changed to a code different from that described in No. 319974. ) A. It is a method of forming a culvert comprising the following steps. From the first step to excavation in the vicinity of the existing or newly installed culvert, a bottom surface 1 long in the front and back of the plane, and left and right wall surfaces 2 and 2 continuously connected to the left and right edges of the bottom surface 1 Front and rear wall surfaces 3, which are continuously arranged upright on the front and rear edges of the bottom surface 1,
Excavate the trench for underdrain, which is composed of b3. Second step ~
The lower part 4 for the hydrophobic material filling layer and the upper part for the top soil filling layer 5 which are formed in the groove for the underdrain with a predetermined dimension in the depth direction and the upper part for the top soil filling layer 5 are formed to form the part 4 for the hydrophobic material filling layer 4. A predetermined location in the depth direction and the culvert are connected by a running water pipe 6. Third Step-After the hydrophobic material b 7 is filled in the hydrophobic material filling layer portion b 4, the topsoil b 8 is filled in the surface soil filling layer portion b 5. B9 is a water retention layer.

B. The dimensions are as follows. Groove width of the underdrain groove ~ 160mm ~ 180mm, depth of the underdrain groove ~ ~ 900mm ~ 1000mm, depth of the hydrophobic material-filled layer part 4 ~ about 2/3 of the depth of the underdrain groove, for running water Depth of the horizon S that matches the height of the pipelo 6 ~ 350 m
About m to 400 mm, the portion b 5 for the topsoil filling layer varies depending on the crop. c. The hydrophobic material B 7 is an unused resource such as shells, lime shells, rice husks, waste wood chips, industrial wastes such as small diameter glass bottles, and lapilli.

D. The effects are as follows. a) Since the trench digger can work with an existing tractor, there is no worry of trampling, and the number and depth of underdrain can be selected according to the field at any time regardless of the date. b) The excavation ditch of the ditcher is as narrow as 180 m / m, and the replacement rate of topsoil and bottom soil is small. c) The digging speed of the trench digger is 900 m / m and the drilling speed is 4 hours / hour
00m-600m, 5 times more than excavator excavation
It is 7.5 times faster and more efficient. d) Use a hydrophobic machine that does not rot, such as shells and glass bottles that are industrial waste. Also, since lapilli can be used depending on the area, the material cost can be saved and there is no trouble due to freezing. e) In the conventional method, the underdrain method is designed with the idea of draining all rainwater, but rainwater is stored at the bottom of the hydrophobic material, and when the topsoil is dried, the water content is raised by natural control to replenish the topsoil. be able to.

Good results were obtained by supplying with hydrophobic materials (shells, lapilli).

[0017]

Since the present invention is configured as described above, it has the following effects. A. As the hydrophobic material, non-rotating materials such as industrial waste shells and small glass bottles are used. Also, volcanic gravel can be used depending on the area. You can save on material costs and there are no troubles due to freezing. B. Farmers can work on their own without resorting to subsidies. Also, the pitch and depth of the underdrain can be determined by judging whether the field penetrates or not, and the construction can be performed. C. In the conventional method, the underdrain method is designed with the idea of draining all the rainwater, but in the present invention, rainwater is stored at the bottom of the hydrophobic material 6, and when the topsoil 7 is dried, the water content is increased by natural management to make it the topsoil. A construction method for supplying water can be realized. D. It is possible to fill the hydrophobic material smoothly by operating one driver from the driver's seat by pulling the tractor. E. Although the tractor travels along the lateral portion of the underdrain groove, it is difficult to run parallel to the underdrain groove, and the filling can be performed accurately by the correction movement of the end chute that is swingable in the lateral direction. F. With reference to FIG. 17, since the hydrophobic material filling unit 5 moves in the field by the wheel 5A2, the hydrophobic material 6 filled in the underditch groove is used.
The space for soil 8 between the upper surface 6A of the soil and the top soil 7 is to be operated by the filling hopper which passes through the top and bottom of the top soil.
The soil 8A filled in can be made to have a constant thickness. G. Since the left and right inner hoppers alone of the innermost hopper 4 located at the uppermost portion are configured to be tiltable, it is possible to reliably discharge the entire amount of the hydrophobic material. H. INDUSTRIAL APPLICABILITY According to the present invention, it is possible to support the growth of crops even in the case of a small amount of annual rainfall, and greatly contribute to agriculture in an area where there is little sunshine and a rise in temperature is small. I. In addition, it has advantages that it can be manufactured at low cost, it is easy to assemble because it has a small number of parts, and it is economical.
