As a hydrophobic material, rice husk is used because it is a soil improvement material that has an excellent filter effect and is friendly to farmland. However, rice husks have the disadvantage that they are not durable because they are corroded by fermentation and easily lose their function as hydrophobic materials when exposed to water and air, and repairing them takes time and money. In addition, rice husks are filled in the flutes in large quantities, but there is a problem of short supply of rice husks. If crushed stone or the like was used as an alternative, soil entered the drain hole drilled in the drain pipe and had a problem with the filter effect.

In addition, hydrophobic materials such as rice husks and wood chips are not transported uniformly by forming bridges in the middle of transportation, and are not filled into the vertical grooves or the filling amount is not uniform.

In this embodiment, as shown in FIGS. 1 and 5, a vertical drain 30 is formed in the ground by an excavating body 11 while towing a culvert drainage pipe laying device 2 connected to a towing vehicle 1 such as a bulldozer or a tractor. The culvert drainage pipe 14 is laid while being sent out into the longitudinal groove 30, the culvert drainage pipe 14 is covered with a first hydrophobic material 31 such as rice husk, and the hydrophobic material and the first hydrophobic material 31 are covered with this hydrophobic material. Is a laminate of second hydrophobic materials 32 such as different crushed stones.

A pair of traction frames 4 to be connected to the traction vehicle 1 is fixed in parallel with a space on the traction side of the horizontal frame 3 of the underdrain drainage pipe laying device 2 to be pulled by the traction vehicle 1. The traction frame 4 is connected to the traction vehicle 1 via a link mechanism 5. The link mechanism 5 is operated by the drive cylinder 6 to maintain the culvert drainage pipe laying device 2 at a predetermined level and maintain a predetermined excavation depth.

2 to 4, the horizontal frame 3 includes a first hydrophobic material hopper 7 for storing a first hydrophobic material (for example, rice husk, wood chip), and a second hydrophobic material (a first hydrophobic material different from the first hydrophobic material). A second hydrophobic material hopper 8 for storing crushed stone and volcanic gravel) is mounted. In the present invention, the first hydrophobic material covering the culvert drain pipe 14 is selected from hydrophobic materials that have a filter effect on the culvert drain pipe, such as rice husk. In addition, the second hydrophobic material 32 laminated on the first hydrophobic material is selected from a hydrophobic material having water permeability that allows water such as volcanic gravel to easily pass therethrough.

At the lower part of the hydrophobic material discharge port provided at the bottom of the first hydrophobic material hopper 7, the first hydrophobic material 31 discharged from the hydrophobic material discharge port is received and conveyed in the horizontal direction toward the hydrophobic material charging chute 19. A horizontal conveyor 9 is provided. The horizontal conveyor 9 is driven by a motor M that is powered by a conveyor generator 10 mounted on the horizontal frame 3 and rotates. The first hydrophobic material is forcibly conveyed by the horizontal conveying conveyor 9 to be discharged and the first hydrophobic material hopper 7 is prevented from forming a bridge of the first hydrophobic material.

The excavation body 11 has an excavation blade 12 formed at the front edge, and an excavation member 13 is attached to the lower end thereof. As the excavating body 11 advances, the excavating member 13 excavates, and the soil is cut open by the excavating blade 12 to form the longitudinal grooves 30.

In the rear part of the excavated body 11, the flexible underdrain pipe 14 is continuously drawn out and laid on the bottom of the longitudinal groove 30 formed by the incision of the excavated body 11. A curved tubular culvert drainage guide 15 is formed in the vertical direction. A culvert drain pipe 14 is introduced into the culvert drain pipe guide 15 while being rewound from a reel R mounted on the towing vehicle 1.

A pipe pressing roller 16 is arranged at the lower end of the culvert drainage pipe guide portion 15 in order to press the culvert drainage pipe 14 fed into the vertical groove 30 from above and to press-fit it to the bottom of the vertical groove 30. The pipe holding roller 16 is connected to an elevating bar 17, and the level is adjusted by elevating the elevating bar 17 connected to a handle 18 provided on the horizontal frame 3 according to the diameter of the underdrain drainage pipe 14. It is possible.

The carry-out side of the horizontal conveyance conveyor 9 that conveys the first hydrophobic material in the horizontal direction is connected to a cylindrical hydrophobic material charging chute 19 that extends vertically up to just above the outlet of the underdrain drainage pipe guide 15 and is carried out. The first hydrophobic material is charged into the hydrophobic material charging chute 19. On the side of the hydrophobic material charging chute 19 facing the carry-out side of the horizontal transfer conveyor 9, a vertical transfer conveyor 20 is arranged. The first hydrophobic material transported from the horizontal transport conveyor 9 is forcibly vertically transported downward and continuously fed by the vertical transport conveyor 20 being driven vertically downward. It is possible to prevent the first hydrophobic material from clogging the vertical conveyance conveyor 20 and the hydrophobic material charging chute 19 by the vertical conveyance.

The thickness adjusting plate 22 is connected to the elevating bar 23, and the elevating bar 23 connected to the handle 24 provided on the horizontal frame 3 is moved up and down to move the thickness adjusting plate 22 up and down to adjust the opening area. Then, the discharge amount of the first hydrophobic material 31 is adjusted to adjust the coating thickness. The discharge amount of the first hydrophobic material can be adjusted by changing the rotational speed of the horizontal transfer conveyor 9 at the bottom of the first hydrophobic material hopper 7.

The discharge port 25 provided at the bottom of the second hydrophobic material hopper 8 is such that the first hydrophobic material 31 first covers the culvert drainage pipe 14 with the advancement of the culvert drainage pipe laying device 2, and the second It arrange | positions so that the hydrophobic material 32 may be laminated | stacked. The second hydrophobic material discharge port 25 is provided with a height adjustment plate 26 for adjusting the opening area. The thickness adjusting plate 26 is connected to an elevating member 27, and the elevating member 27 connected to a handle 28 provided in the horizontal frame 3 is moved up and down to adjust the opening area of the second hydrophobic material discharge port 25 to be discharged.

A laser receiver mast 29 is erected on the horizontal frame 3. The level is measured by a laser emitted from a laser issuer in the field, and the link mechanism 5 is maintained so that the underdrain drainage pipe laying device 2 is held at a constant level. Is operated by the drive cylinder 6 to control the depth of penetration into the ground.

In FIG. 5, for example, when rice husk as the first hydrophobic material 31 and mullet (volcanic gravel) as the second hydrophobic material 32 are stacked on the culvert drain pipe 14, water is always present up to 10 cm above the culvert drain pipe 14. Because of this, rice husks within that range are less likely to rot. In addition, when volcanic gravel is stacked on rice husks, even if the water goes up and down, it can function as a hydrophobic material without any problem in durability. Therefore, a filter effect can be obtained by accurately forming a rice husk layer to a thickness smaller than that of a conventional culvert drain pipe 10 cm or less by using the culvert drain pipe laying apparatus of the present invention and laminating volcanic gravel thereon. At the same time, the shortage of rice husk supply can be overcome, and the durability of the underdrain is improved.
