Abstract

【課題】土のう袋を積上げる時、従来型の土のう袋では形状が不揃いである上、土のう同士の結束に於いては上部の紐のみで結束する為、安定性がない。土のう袋の形状を一定にする事により、安定性・強度・施工能率の向上ができる角形連結式土のう袋を提供する。
【解決手段】土のう袋の両側面（長手方向）に紐を縫いこみ、連結用の紐を取り付ける。袋の口は、ミシンによる縫合。
【選択図】図２[PROBLEMS] When stacking sandbags, the shape of a conventional sandbag is not uniform, and the binding of sandbags is not stable because only the upper string is used to bind the sandbags. To provide a square-connected sandbag that can improve stability, strength and construction efficiency by keeping the shape of the sandbag constant.
A string is sewn on both sides (longitudinal direction) of a sandbag and a connecting string is attached. The mouth of the bag is sutured with a sewing machine.

Description

今までの土のう袋は、シール口を巾着状に閉める構造のものであり、施工する場合は土のう同士を結合する方法として、巾着状に締めた土のうの口同士を絡めて縛ったり、予め土のう袋の底辺部分をミシンで縫いつけたものをペアで利用していた。
この方法では一方向の隣同士は結束できても、四方向の連結は出来ない。
一方向の結束だけでは不安定であり、強度的にも不安があった。Until now, sandbags have a structure in which the sealing opening is closed in a drawstring shape. Sewn with a sewing machine at the bottom part of the pair.
In this method, four directions cannot be connected even if the neighbors in one direction can be bound.
It was unstable with only one-way unity, and there was an uneasiness in strength.

Issues that the device is trying to solve

災害復旧や土木工事に利用されている土のう袋は、シール口を巾着状に縛って使用するが、形状が不揃いで安定的でなく、強度的にも不安がある。
施工上に容易さと施工構造物の安定性・強度などの施工性能を確保する為、土のう袋の両端に長めの紐を縫いこむことにより、四方向（周囲の）土のう同士の角を連結して固定出来る構造を持った土のう袋が、優れた施工性能を発揮する工法を可能にする。Sandbags used for disaster recovery and civil engineering work are used with the seal opening tied in a drawstring shape, but the shapes are not uniform and are not stable, and there is concern about strength.
In order to secure ease of construction and construction performance such as stability and strength of the construction structure, long strings are sewn on both ends of the sandbag to connect the corners of the sandbags in four directions (surroundings). A sandbag with a structure that can be fixed enables a construction method that demonstrates excellent construction performance.

Industrial applications

斜面崩壊の保全対策など保全工事や、災害復旧工事建築物基礎補強工事に用いる土のうの性能上、本考案の土のう袋の構造とシール口のミシン縫いによる整った長方形の形状は施工上の容易さと施工構造物の安定性・強度や施工性能に優れたものになり得るものである。Due to the performance of sandbags used for maintenance work such as slope slope maintenance measures and disaster restoration work, and for building foundation reinforcement work, the structure of the sandbags of the present invention and the well-formed rectangular shape of the seal opening by sewing are easy to construct. It can be excellent in stability / strength and construction performance of construction structure.

Claims

Sandbags used for disaster recovery and civil engineering work are used with their sealing openings tied in a drawstring shape, but their shapes are irregular and not stable. In order to stably and stably stack the sandbags, the sandbags are sewn with a string that is long in the longitudinal direction on both sides and is resistant to corrosion strength in a direction perpendicular to the sealing opening of the sandbag, and the four corners are adjacent to each other. Sandbag structure, which can be connected and fixed.
