Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to, for example, laying a sheet at the bottom of a landfill site to reduce the load at the time of laying the landfill, because stable landfill cannot be performed if the ground is soft and the landfill is laid directly. The present invention relates to a sheet laying method that can be applied when dispersing or laying a waterproof sheet in a landfill.

[0002]

2. Description of the Related Art Conventionally, for example, as described above, a sheet is laid in a landfill to disperse a load at the time of laying a landfill earth and to perform a stable landfill or to have a function as a water-impermeable sheet. However, laying and laying the sheet at the appropriate laying position while maintaining the correct overlap width at the bottom of the landfill requires a high level of skill, and it is not possible to improve the construction efficiency. It was very difficult.

[0003]

According to the present invention, for example, a barge having water filled in a landfill and a roll-shaped sheet loaded on the surface of the land is drawn by a winch via a pulley attached to a backhoe. By moving the barge to the seat laying position without fail and laying the seat, the efficiency of the laying work can be improved, and the position can be finely adjusted by the pulley attached to the backhoe. And a sheet laying method capable of laying a sheet at an accurate laying position.

[0004]

According to the present invention, a barge is floated on a water surface stretched in a predetermined place, a roll-shaped sheet is loaded on the barge, and a guide wire is attached to one side of the barge. The pull wire is connected to the winch via a pulley attached to the moving body, and while the guide wire is being fed, the winch is wound up with the barge pull wire and the sheet is laid while pulling the barge to the opposite shore. Move to the next sheet laying position, connect the wire drop frame to the guide wire, connect the barge pull wire from the winch to the wire drop frame via the pulley of the moving body, and connect the wire drop frame to the barge. After pulling and fixing, it consists of a method of laying sheets on a predetermined place where the laying of sheets is repeated while laying sheets while pulling the barge to the opposite shore in the same procedure as described above. Or a landfill the Teichi, also consist of a sheet laying method using a backhoe as mobile.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A seat laying procedure according to an embodiment to which a sheet laying method of the present invention is applied will be described below with reference to the drawings. First, in FIG. 1, water is laid to lay a net-shaped sheet 2 shown in FIG. 2 and the like in a landfill 1, and a barge 3 for laying a sheet is mounted on the water surface with a truck crane 4 or the like as shown in FIG. Assemble using In the embodiment of the present invention, the barge 3 that can be assembled on the surface of the water is assembled on site. However, when the barge 3 can be transported by a large trailer or the like, the barge 3 is mounted. The truck may be directly floated on the water surface by the truck crane 4 or the like.

Next, in a land yard or the like, a roll-shaped sheet wound into a roll having an appropriate size is transported by a transport truck 5 and loaded on the barge 3 by a truck crane 4 or the like. Further, as shown in FIGS. 5 and 6, a triangular projecting member 6 is attached to one side of the barge 3, and a buoy 17 is provided therebelow. A guide wire 7 is attached to the projecting member 6 as shown in FIG. 2, and this guide wire 7 is used as a center for moving the barge 3 to the next seat laying position as shown in FIG. Attach to

In the state shown in FIG. 2, two barge pull wires 8 each having an end attached to the barge 3 are connected to respective fixed winches 11 via pulleys 10 as shown in FIG. , The guide wire 7 is unreeled from the movable winch 14 in the direction of arrow A, and the trolley wire 8 is wound up by the fixed winch 11, and
Is laid as shown in the figure while drawing the sheet 2 on the opposite bank in the direction of arrow A. The above-mentioned pulley 10 is attached to a bucket 12 provided on an arm or the like of the backhoe 9 not shown in FIG. 9 via a wire 13 having a length of about 1 m, for example. , The position and direction of the pulley 10 can be easily finely adjusted.
3 can provide some flexibility in the vertical direction of the pulley 10.

Next, as shown in FIG. 3, the barge 3 is moved in the direction of the arrow H by the baux 9 to the next seat laying position.
A wire pull-in frame 15 with styrofoam 19 as shown in FIGS. 7 and 8 is connected to the guide wire 7, and a pulley 10 in which the barge pull wire 8 is attached to the backhoe 9 by a fixed winch 11 is connected to the wire pull-in frame 15. Connected to the barge 3 with the movable winch 14
5 is pulled in the direction of arrow B and fixed.

Note that the two backhoes 9 shown in FIG. 3 may be moved from the opposite bank shown in FIG. Next, as shown in FIG. 4, the barge 3 is connected to the barge pull wire 8 via a pulley 10 attached to the backhoe 9 with two fixed winches 11.
And laying the sheet 2 while pulling it in the direction of arrow C to the opposite bank, during which the guide wire 7 is moved by the movable winch 1
It is paid out from 4.

[0010] By repeating each operation procedure described above with reference to FIGS. 2, 3 and 4, the sheet 2
The fixed winch 11 and the movable winch 14 provided on both sides in FIGS. 2 and 3 are driven by the electric power generated by the generator 18.

[0011]

According to the method for laying sheets in a landfill, for example, according to the present invention described above, a barge assembled on a water surface stretched in a landfill is placed, and rolled sheets are loaded on the barge. By pulling the barge with a winch via a pulley attached to the backhoe, the barge surely moves to the seat laying position and lays the sheets, so that the efficiency of the sheet laying work can be improved.

Further, according to the present invention, fine adjustment of the position of the pulley can be easily performed when laying the seat while retracting the barge by winding the barge pulling wire by the winch via the pulley attached to the backhoe. In addition, the sheet can be laid at an appropriate position.
