Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydrophobic material filling device for a culvert.

[0002]

2. Description of the Related Art Conventionally, as a method of constructing a culvert, a method of arranging an earth pipe on the bottom of the culvert is general, and this is the first method of filling a hydrophobic material.

[0003]

The above-mentioned prior art has the following problems. Conventionally, there has been an example in which a wood chip material or the like is filled on an earth pipe at the bottom of a culvert, but all of them rely on manual labor. SUMMARY OF THE INVENTION The present invention has been made in view of such problems of the related art, and has as its object to provide the following.
This is a system for establishing a new culvert method, and is an indispensable device for a single farmer to efficiently and efficiently construct a vast field by a single farmer. This is the background that requires the present invention, and will be specifically described below with reference to FIGS.

A. In a conventional underdrainage method in an upland field and a pasture, 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 groove. Since a person enters the V-shaped groove to perform work, the groove width needs to be about 600 m / m to 1000 m / m, and the depth needs to be about 900 m / m to 1000 m / m.

B. In what was described in the prior art,
It had the following problems. a. Since the power shovel (weight 18 ton) enters the field, the soil is hardened by the treading pressure, and the permeation of moisture is deteriorated. b. Soil containing organic matter due to large excavation volume (topsoil)
And the replacement of mineral soil at the bottom causes adverse effects on crops. c. The working speed of the power shovel is as low as 80 m / h. In addition, labor and material costs such as clay pipes are required. d. The buried clay pipes will be from two years due to vibrations caused by tractor work
The waterway will be shut off because it will be damaged in about three years. In a cold region, damage due to freezing occurs.

C. As a solution to the problems of the prior art, the applicant has previously proposed the following proposal in Japanese Patent Application No. 10-319.
974. (For convenience of explanation,
The reference numeral is changed to a reference numeral different from that described in US Pat. A). This is a method for forming a culvert consisting of the following steps. 1st process-Excavation of the vicinity of the existing or newly built drainage boiler, and a bottom surface B1 long in front and rear of the plane, and left and right wall surfaces B2, B2 connected to the left and right edges of the bottom surface B1 in an upright state, Front and rear wall surfaces 3 connected to the front and rear edges of the bottom surface 1 in an upright state,
Excavate the culvert ditch b composed of b3. Second step ~
A lower part B for the hydrophobic material filling layer and a part B 5 for the upper surface soil filling layer formed with predetermined dimensions in the depth direction in the culvert groove B are formed. A predetermined location in the depth direction and the culvert b are connected by a running water pipe 6. Third Step-After filling the hydrophobic material-filled layer part B 4 with the hydrophobic material B 7, the topsoil fill layer part B 5 is filled with the topsoil B 8. B9 is a water retention layer.

B. The dimensions are as follows. Groove width of culvert ditch ~ 160mm ~ 180mm, depth of ditch for ditch ~ 900mm ~ 1000mm, depth of hydrophobic material filled layer partial b4 ~ about 2/3 of depth of ditch for ditch culvert, running water The depth of the horizontal line S that matches the height of the pipe 6 ~ 350 m
About m to 400 mm, the part 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 chips, industrial waste such as small-diameter glass bottles, and lapilli.

D. The effects are as follows. a) Since the trench excavator can be operated with the existing tractor, there is no need to worry about treading pressure, and the number and depth of culverts according to the field can be selected at any time regardless of the date. b) The excavation trench of the trench excavator is as narrow as 180 m / m, and the exchange rate between the top soil and the bottom soil is small. c) The excavation speed of the trench excavator is 4 hours / hour at an excavation depth of 900 m / m.
00m to 600m, 5 times larger than excavator excavation
It is 7.5 times faster and more efficient. d) A hydrophobic machine that does not rot, such as shells and small-sized glass bottles that are industrial waste, is used. Also, since volcanic rubble can be used in some areas, material costs can be saved and there is no trouble due to freezing. e) In the conventional method, the culvert method is designed with the idea of draining all the rainwater. However, rainwater is stored at the bottom of the hydrophobic material, and when the topsoil is dried, the water is raised by natural management to replenish the water to the topsoil. be able to.

It is good as a result of supplying with hydrophobic materials (shells, volcanic debris).

[0017]

Since the present invention is configured as described above, the following effects can be obtained. A. As the hydrophobic material, non-rottable ones such as shells and small-diameter glass bottles, which are industrial waste, are used. Volcanic pebbles can also be used in some areas. Material costs can be saved, and there is no trouble caused by freezing. B. Farmers can work on their own without relying on subsidies. In addition, it is possible to determine the pitch and depth of the culvert by judging whether the penetration of the field is good or not, and to perform the work. C. In the conventional method, the culvert method is designed with the idea of draining all the rainwater. However, in the present invention, the rainwater is stored at the bottom of the hydrophobic material 6, and when the topsoil 7 is dried, the moisture is raised by natural management, and the topsoil is removed. A method for replenishing water can be realized. D. The operation can be performed by one driver from the driver's seat by tractor towing, and the hydrophobic material can be filled smoothly. E. FIG. Although the tractor travels along the side of the culvert groove, it is difficult to run in parallel with the culvert groove, and the filling can be accurately performed by correcting movement of the end chute configured to be able to swing laterally. F. Referring to FIG. 17, since hydrophobic material filling section 5 moves in the field by wheels 5A2, hydrophobic material 6 filled in the culvert groove is provided.
The soil filling space 8 between the upper surface 6A of the top soil and the top soil 7 acts as a filling hopper on the top and bottom of the top soil.
The soil 8A to be filled into the container can have a constant thickness. G. FIG. Since the left and right internal hoppers alone of the inner hopper 4 located at the uppermost portion are configured to be tiltable, the entire amount of the hydrophobic material can be reliably discharged. H. INDUSTRIAL APPLICABILITY The present invention can help grow crops even when the amount of annual rainfall is small, and can greatly contribute to agriculture in an area where sunlight is short and temperature rise is small. I. In addition, it can be manufactured at a low cost, is easy to assemble because the number of parts is small, and is economical.
