Description
【考案の詳細な説明】
本考案はマンホール間における電力、通信用ケーブル等
の管路のうちで未使用管路等の閉塞に用いる比較的大型
の防水栓に関するものである。[Detailed Description of the Invention] The present invention relates to a relatively large waterproof plug used for blocking unused conduits between manholes for power, communication cables, etc.
マンホール間における管路においては、使用管路はもち
ろんのこと、未使用管路においても管路を伝ってマンホ
ール内に水が流入するのを防止し、他の管路等に影響を
及ぼさない様に防水を施さねばならない。In the pipes between manholes, water should be prevented from flowing into the manhole through the pipes, not only in used pipes, but also in unused pipes, so as not to affect other pipes, etc. must be waterproofed.
そこで従来においては、管路口が鉄管である場合には、
訪日に発泡性のポリウレタンやモルタル等を隔離板を介
して充填して防水処理を施していたものであるが、該作
業は取付、取外し時間及び作業工数が増加し、また防水
効果にういても不完全であった。Therefore, conventionally, when the pipe entrance is an iron pipe,
When visiting Japan, waterproofing was applied by filling foaming polyurethane, mortar, etc. through a separator, but this work increased installation and removal time and man-hours, and the waterproofing effect was not good. It was incomplete.
本考案は上記した点に着目してなされたものであり、取
付、取外し作業が容易であり、且つ防水効果において優
れている防水栓を提供せんとするものである。The present invention has been developed with the above-mentioned points in mind, and it is an object of the present invention to provide a waterproof plug that is easy to install and remove, and has an excellent waterproof effect.
以下本考案の一実施例について図面と共に説明すれば、
１はゴム製の円筒状の栓体であり、その外周面２はテー
パー状に形成されている。An embodiment of the present invention will be described below with reference to the drawings.
1 is a cylindrical stopper made of rubber, and its outer peripheral surface 2 is tapered.
栓体１の外側面には中央部に枚用大孔３が形成され、ま
た該枚用大孔３の外側にはこれを囲んで複数個の横用小
孔４が形成されている。A large sheet hole 3 is formed in the center of the outer surface of the plug body 1, and a plurality of horizontal small holes 4 are formed on the outside of the large sheet hole 3 to surround it.
楔用犬、小孔３゜４には中間の段部３ａ、４ａを介して
内部に挟小部３ｂ、４ｂが形成されている。In the wedge dog and small hole 3.4, pinching portions 3b and 4b are formed inside via intermediate step portions 3a and 4a.
而して５，６はそれぞれ大孔３と小孔４に打ち込まれる
硬質塩化ビニル製の大、小の楔を示し、数枚５，６には
軸方向に空気抜き用穴５ａ、６ａが形成されている。Numerals 5 and 6 indicate large and small wedges made of hard vinyl chloride that are driven into the large hole 3 and small hole 4, respectively, and several wedges 5 and 6 have air vent holes 5a and 6a formed in the axial direction. ing.
楔５，６の外周面には引き抜き用工具の係止用凹部５ｂ
、６ｂが猛威されている。The outer peripheral surfaces of the wedges 5 and 6 are provided with recesses 5b for locking the extraction tool.
, 6b is being rampant.
上記構成において、使用時においては、栓体１を管路ロ
アに嵌合した後、先づ外周面にグリスを塗付した楔５を
大孔３にハンマー等で打込み、次でその外側の小孔４に
楔６を打込むことにより栓体１は管路７内に圧縮され、
防水処理は完全になされる。In the above configuration, when in use, after the plug body 1 is fitted into the conduit lower, the wedge 5 whose outer circumferential surface is coated with grease is first driven into the large hole 3 with a hammer or the like, and then the outside small By driving the wedge 6 into the hole 4, the plug 1 is compressed into the pipe 7,
Waterproofing treatment is done completely.
楔の打込時においては、第１図に示される如く楔５，６
を孔３，４に対し楔５，６が段部３ａｔ４ａに達するま
で容易に挿入して支持させ、その後に挟小部に対して打
ち込む。When driving the wedges, as shown in Fig. 1, the wedges 5 and 6 are
The wedges 5, 6 are easily inserted into the holes 3, 4 until they reach the stepped portions 3at4a and supported, and then driven into the narrow portions.
本考案は上記した如くに、栓体に対して枚用大孔を囲ん
で複数個の横用小孔を設けたものであるから、第１段階
において大枚を栓体に打込んで第１次圧縮をし、第２段
階においては小楔を打込んで第２次圧縮を施すことを可
能とすると共に該第１次圧縮が栓体の中心部に対する大
枚の打込みにより圧縮効果力凋囲に点在する複数の小孔
間より栓体の外周端部全部に及ぶ全体的圧縮であるのに
封部該第２次圧縮が栓体の外周部に対する複数個の小楔
の打込みにより圧縮効果が周囲の一部に及ぶ局部的圧縮
であるので該大、小の楔の打込みが容易になし得られ、
且つ一個の大枚と複数個の小楔の組合せにより全体とし
て栓体を充分に圧縮して防水性を確保することができる
。As described above, in the present invention, a plurality of horizontal small holes are provided in the plug body surrounding the large hole for the sheet, so in the first step, the large sheet is driven into the plug body and the first In the second stage, a small wedge is driven in to perform the second compression, and the first compression is performed by driving a large wedge into the center of the plug, which increases the compression effect. Although the overall compression is applied to the entire outer circumferential end of the plug body from between the plurality of small holes scattered in the sealing body, the secondary compression is achieved by driving a plurality of small wedges into the outer circumference of the plug body. Since this is a local compression that covers a part of the periphery, it is easy to drive large and small wedges.
In addition, the combination of one large piece and a plurality of small wedges can sufficiently compress the plug as a whole to ensure waterproofness.
