Grouting leakage-proof device for rear pile type jacket foundation and technological method of grouting leakage-proof device
The invention provides a rear pile type jacket foundation grouting anti-leakage device and a technological method thereof, and belongs to the technical field of offshore jacket foundation installation and construction. The using principle is that a diver fills cotton cloth or other soft materials which have a certain plugging function and are convenient to operate in an annular area in a main pipe of a jacket and outside a steel pile underwater, then a thick cable is attached to the bottom of the main pipe and surrounds the steel pile, and the two ends of the thick cable are tightened through euphroes; and the cotton cloth in the annular area can be held by the thick cable. And then a small amount of grouting material is poured for solidification, so that the part of solidified grouting material forms a new plugging layer, then water is injected inwards from the top of the annular area, if the water surface of the injected water does not descend basically, it is indicated that the sealing performance of the annular grouting area is good, the grout leakage prevention purpose is achieved, and follow-up normal grouting operation can be carried out.
本发明提供一种后桩型导管架基础灌浆防漏浆装置及其工艺方法，属于海上导管架基础安装施工技术领域。其使用原理是：潜水员水下对导管架主管管内与钢桩桩外的环形区域进行填充棉布或其他具备一定封堵功能的便于操作的软质材料，然后用粗缆绳贴住主管底部并围绕钢桩，粗缆绳两端用紧绳器收紧，保证粗缆绳可兜住环形区域内的棉布。然后灌少量灌浆料进行凝固，使得此部分凝固的灌浆料形成新的封堵层，然后从环形区域顶部向内注满水，若所注水水面基本不下降，则说明环形灌浆区域密封性较好，防漏浆目的达成，可进行后续的正常灌浆作业。
