【発明の詳細な説明】
本発明は原子力プラントの建屋の壁や床の配管
貫通部のしやへい方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for sealing pipe penetrations in walls and floors of nuclear power plant buildings.
従来、建屋の壁や床の貫通配管と埋込スリーブ
の間に生ずる間隙のしやへい欠損を補うために、
鉛毛等を充填している。 Conventionally, in order to compensate for the gaps that occur between penetrating pipes and embedded sleeves in the walls and floors of buildings,
Filled with lead hair, etc.
しかしながら、この方法では、貫通配管が原子
炉圧力容器バウンダリーの一部または、内部流体

た鉛毛が配管表面と接触し、配管を拘束し大きな
応力を発生させる可能性がある。また、長年月の
間に充填された鉛毛が片寄り空隙が生ずるおそれ
がある。 However, in this method, if the penetrating piping is part of the reactor pressure vessel boundary, or if the internal fluid is high temperature and the amount of displacement due to heat is large, the filled lead hairs will come into contact with the piping surface, restraining the piping and causing large stress. may occur. In addition, there is a risk that the lead hairs filled over many years may become uneven and create voids.
本発明は上述の事情を考慮してなされたもの
で、配管の移動を拘束することなく、有効なしや
へい効果のあるしやへい方法を提供することを目
的としている。 The present invention has been made in consideration of the above-mentioned circumstances, and it is an object of the present invention to provide a sealing method that is effective and has a sealing effect without restricting the movement of piping.

定する。 An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, in the pipe penetration part shielding method of the present invention, an embedded sleeve 3 is installed at the pipe penetration part of the building wall 2, and the pipe 1 is inserted into the embedded sleeve 3.
penetrates. A corrugated plate 6 is wrapped around the pipe 1.
Lead bristles 5 are provided in the gap between the corrugated plate 6 and the embedded sleeve 3.
is filled, and the lead bristles 5 are held down by lead bristles holding plates 4 at both ends of the penetrating portion. The lead wool presser plate is fixed to the embedded sleeve 3.
第３図は波状板６の拡大図で、油状板６は貫通
孔１の径に合せて円筒状に巻いた後溶接等で固定
する。 FIG. 3 is an enlarged view of the corrugated plate 6. The oily plate 6 is rolled into a cylindrical shape to match the diameter of the through hole 1 and then fixed by welding or the like.

状板６がない場合と、ほとんど変らない。 In FIGS. 1 and 2, the through pipe 1 undergoes displacement due to thermal changes in the internal fluid. At this time, the corrugated plate 6 is in contact with the through pipe 1, but since its area is small, the pipe is not restricted and the design conditions are not changed. On the other hand, the shielding effect is almost the same as when the corrugated plate 6 is not provided.
第４図、第５図は本発明の他の実施例における
波状板６で埋込スリーブ３との間に複数の仕切板
７を取つける事により鉛毛の片寄り、落下等を防
止する事ができる。 FIGS. 4 and 5 show another embodiment of the present invention in which a plurality of partition plates 7 are installed between a corrugated plate 6 and an embedded sleeve 3 to prevent lead hair from shifting or falling. I can do it.

る。 As described above, in the shearing method of the present invention, by wrapping a corrugated plate around the through piping, the shearing effect can be maintained without restricting the displacement of the piping system mainly in the axial direction. Furthermore, compared to conventional methods, it is possible to increase the effect with the addition of only a few parts.
