摘要： The present invention is directed to sealable rock bolts (30) that prevent water leakage through the bolt, a kit containing portions of such bolts prior to assembly, installation, and use, and a method of using such sealable rock bolts. Such rock bolts are fastened in place in a roof, wall, or bottom of an underground region via pressure fitting or the like. The rock bolt contains a sealing unit (31) that contains a liquid water activated, expandable hydrophobic pre-polymeric resin (34). The sealing unit has side, top, and bottom portions that are degradable by water to permit the resin to expand upon contact with water and to seal the bolt to prevent water passage through the bolt.

摘要： A dispensing device and method, especially adapted for use in sealing high pressure fluid leaks, is disclosed. Such use requires high pressure dispensing of sealant. Such sealants are formed by an exothermic reaction of at least two liquid substances that generates high pressures within the dispensing device. Such pressures could potentially harm the feeding system of the device due to pressure backflow. This problem is solved by providing a check valve (14) in the mixing and reaction chamber of the device to protect the feeding system. A static mixer is disposed within the chamber to enhance mixing and reaction of the substances.
摘要翻译：公开了一种特别适用于密封高压流体泄漏的分配装置和方法。这种使用需要高密度分配密封剂。这种密封剂由在分配装置内产生高压的至少两种液体物质的放热反应形成。由于压力回流，这种压力可能会对装置的进料系统造成危害。通过在装置的混合和反应室中设置止回阀（14）以保护进料系统来解决这个问题。静态混合器设置在室内以增强物质的混合和反应。
