Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bag for accommodating and transporting residual soil generated at a construction site inside.

[0002]

[Prior art]

 Conventionally, the residual soil generated at the construction site was loaded into a dump truck by heavy equipment such as a backhoe, and then discharged and transported. However, in areas where these heavy equipment cannot be used, for example, in a mountainous area for a transmission line steel tower foundation construction site, in order to discharge and transport excavated soil and stone blocks, the soil is left in a large bag. I put it in, hung this bag around four helicopters, and carried it to the disposal site for the remaining soil. The bag-shaped bag used for discharging / transporting has a body and a bottom joined by welding or adhesion.

[0003] Since the bag for transporting the residual soil contains about 400 kg of residual soil per bag, 4 to 5 workers need to lift the bottom of the bag to discharge the residual soil. I had to turn the bag upside down.

[0004]

[Problems to be solved by the device]

 However, as described above, in the bag-like bag used for discharging and transporting the residual soil, the body and the bottom are joined by welding or adhesion. When the bag-shaped bag is formed by welding or adhesion as described above, the bag-shaped bag can be easily formed, but the bag-shaped bag lacks strength and has a drawback that the bottom is pulled out. In particular, in order to transport the residual soil discharged from the transmission line steel tower foundation construction site, since each bag stores around 400 kg of residual soil, the bag itself is very easy to tear due to the weight of the residual soil. In addition, there are many foreign matters such as stone blocks and tree branches in the remaining soil, and these foreign matters have a drawback that the bag itself is easily damaged and damaged.

Further, in order to discharge the residual soil from the bag, the top and bottom of the bag are turned upside down and the residual soil contained inside the bag is discharged, but the bag containing the residual soil has a weight of 400 kg before and after, It was very difficult to lift the bottom of the bag upward to support and fix it, and a lot of manpower was required for the work of discharging the residual soil.

Therefore, the present invention has been proposed in view of the problems of the above-mentioned conventional techniques, and the purpose thereof is to have sufficient strength to convey the residual soil and to discharge the residual soil. It is to provide a simple bag for transporting residual soil.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention is a bag comprising a tubular body portion having an open upper end and a bottom portion closing the bottom surface of the body portion. The lower end of the section is bent toward the inside of the bag to form a bent section, and the outer peripheral end of the bottom section is folded back toward the inside of the bag to form a folded section, and the bent section and the folded section are described above. It is characterized by being sewn together.

According to the second aspect of the present invention, strip-shaped reinforcing cloths are sewn and attached to the outer peripheral surface of the bag from the upper end opening of the body to the middle of the bottom so as to face each other, and the reinforcing cloths are also attached. A loop-shaped discharge rope insertion portion is formed at an end portion on the bottom side of the, and the discharge rope is inserted through and fixed to the discharge rope insertion portion.

Further, in the invention according to claim 3, a plurality of reinforcing cloths are provided so as to face each other.
