【考案の詳細な説明】 本考案は水道管等の圧力管に部分的に断水を行う必要の
ある種々の工事を旋す際に水道管を任意の範囲に限定し
て断水可能とせしめる為の制水装置に関する。[Detailed description of the invention] The present invention is designed to limit the water supply pipes to an arbitrary range when conducting various types of construction work that require a partial water cutoff to pressure pipes such as water pipes. Regarding water control devices.

従来、網目状或いは樹枝状に設けられている水道管は、
一部を除いて殆んどが両押しの状態である為、前記工事
の機工に当っては、その区域の両側の最も近くに設けら
れている制水弁で止水する方法が用いられていた。Traditionally, water pipes are arranged in a mesh or dendritic shape.
With the exception of a few areas, most of the area is double-sided, so when constructing the construction, the method used is to shut off the water with the water control valves installed closest to both sides of the area. Ta.

しかしながら、斯かる方法では、任意の区域を断水状態

ａ内で、棒状体すに支持された膨張、収縮可能な袋Ｃを
膨らませることにより、水道管ａの適宜の個所を遮断し
得るようにした制水装置が提案されている。However, in such a method, water control valves are not necessarily installed in appropriate locations in order to cut off water to a given area, and in most cases, a wide area has to be cut off. Recently, as shown in Figure 5, expansion and contraction of water pipes supported by rod-shaped bodies in water pipes a for the purpose of water cut-off has been causing trouble to households outside the scope of construction. A water control device has been proposed in which a suitable portion of a water pipe a can be shut off by inflating a bag C that can be closed.

この方式によれば水道管ａを任意の範囲に限定して断水
でき、断水が機工範囲外まで及ぶということがなくなる
。According to this method, water can be cut off by limiting the water pipe a to an arbitrary range, and there is no possibility that the water cut will extend beyond the mechanical range.

道管ａに適用した場合には止水性を失なうことになるの
で、実質的には固定部上下間隔と略々等しい直径の水道
管ａにしか適用できない不利があった。However, in this method, in order to avoid troubles such as the bag C getting stuck in the insertion port a' of the water pipe a and being unable to be inserted during insertion, at least the lower end of the rod-shaped body is connected to the bottom end of the bag C. For example, as shown in FIG. 5, the bag C is fixed to the rod-shaped body at two places, the top and the bottom. In this case, when the bag C is inflated, Even if the upper and lower fixing parts could be expected to expand due to the elongation of the constituent materials, they would hardly be able to expand beyond the bulge state shown in Figure 5, and the rod-shaped body would inevitably expand. Not only will the water-stopping properties around the area deteriorate, but if it is applied to a water pipe a that has a larger diameter (inner diameter) than the interval between the upper and lower fixed parts, it will lose its water-stopping properties, so it is effectively fixed. There was a disadvantage that it could only be applied to water pipes a whose diameter was approximately equal to the vertical distance between the sections.

る不利を招く。In this method, the posture of the rod-shaped body inserted into the water supply 'la is held in a vertical position against the water pressure, and the fixed part at the lower end of the bag C is moved from the lower end of the rod-shaped body when it expands. In order to eliminate the risk of it coming off, it is necessary to form an insertion hole e for the lower end of the rod-shaped body on the lower end side of the water pipe a. This necessity has the disadvantage of complicating the machining process, including repairing holes after the machining is completed.
