  穿壁管密封的制造和装置
  Manufacture and Equipment of Wall-Piercing Pipe Seal
  1. 管道通过防护封闭隔断时,必须与封闭的穿孔管、封闭的法兰和防护电阻板一起埋设。当管道通过封闭的隔断时,必须与封闭的穿孔管和封闭的法兰一起埋设。
  1. When the pipeline passes through the protective closure and partition, it must be buried together with the closed perforated pipe, the closed flange and the protective resistance board. When a pipe passes through a closed partition, it must be buried with a closed perforated pipe and a closed flange.
  2、供水管、压力排水管、电缆等通过管壁封闭的短管,应选用壁厚大于3mm的钢管。
  2. When water supply pipes, pressure drainage pipes, cables and other short pipes are enclosed through the wall of the pipe, the pipe with a wall thickness greater than 3 mm should be selected.
  3、通风管道通过管壁封闭的短管,应选用厚度为2—3mm的钢板焊接制造,焊缝应饱满、均匀、紧密。
  3. When the ventilation pipeline passes through the short pipe which is closed by the pipe wall, the steel plate with thickness of 2-3 mm should be welded and manufactured. The welding seam should be full, uniform and compact.
  钢板应平整,机翼高度应在30 - 50mm之间。封闭翼圈与穿墙封闭管接头部位应完全焊接。
  The steel plate should be flat and the height of the wing should be between 30 and 50 mm. The joint between the closed wing ring and the closed pipe through the wall should be welded completely.
  5. 封闭翼圈应位于墙体厚度中心,并与周围结构的钢筋焊接。
  5. Closed wing rings should be located in the center of wall thickness and welded with the reinforcement of surrounding structures.
  6. 伸出墙体的短管两端长度应符合以下规定:
  6. The length of both ends of the short pipe extending out of the wall shall conform to the following provisions:
  (1)穿过墙体短管的电缆和电线长度为30-50mm;
  (1) The length of cables and wires passing through short wall tubes is 30-50 mm;
  (2)穿墙给排水管道大于40mm;
  (2) The water supply and drainage pipeline through the wall is more than 40 mm.
  (3)穿墙短通气管道应大于100mm。
  (3) Short ventilation pipe through wall should be more than 100 mm.
  7. 穿墙短管作为套管使用时应满足以下要求:
  7. The wall-piercing short pipe should meet the following requirements when used as casing:
  (1)在套管与管道之间填充密封材料,并在管口两端密封。
  (1) Fill the sealing material between the casing and the pipeline, and seal at both ends of the pipe mouth.
  (2)套管内不得有接口;
  (2) There shall be no interface in the casing;
  (3)套管内径应比管道外径大30-40mm。
  (3) The inner diameter of casing should be 30-40 mm larger than the outer diameter of pipeline.
  8. 穿过管壁的封闭管道应在激波端部设置防护电阻板。电阻板采用厚度大于6mm的钢板制作。插入两个电阻片的槽是必要的。
  8. A protective resistor plate shall be installed at the end of shock wave for a closed pipe passing through the wall. Resistance plate is made of steel plate with thickness greater than 6 mm. It is necessary to insert slots for two resistors.
  9. 当同一位置有多条管线需要通过管壁封闭时,可以在封闭的通过管壁的总管两端焊接一个密封翼环。两翼密封圈均应与现场墙体钢筋焊接,墙体不得外露。
  9. When multiple pipelines need to be closed through the wall at the same location, a sealing ring can be welded at both ends of the main pipe through the wall. The sealing rings on both wings should be welded with the steel bars on the site wall, and the wall should not be exposed.
