Underwater pouring sealing system adopting expanded polymer and sealing method thereof
The invention belongs to the technical field of marine engineering construction, and particularly relates to an underwater pouring sealing system adopting an expanded polymer and a sealing method thereof. The underwater pouring sealing system comprises a marine equipment foundation placed on a seabed, a group of steel pipe piles inserted into the seabed, and a group of sleeves fixedly arranged around the bottom of the marine equipment foundation, wherein the sleeves are in sleeve joint with the outsides of corresponding steel pipe piles. The underwater pouring sealing system is characterized in that two sealing strips are arranged above and below an aperture between each sleeve and each steel pipe pile, the two sealing strips partition the aperture between each sleeve and each steel pipe pile into a first annular space and a second annular space, each second annular space is filled with the expanded polymer, and concrete is poured into each first annular space, so that the sleeves arefixedly connected with the steel pipe piles. According to the underwater pouring sealing system and method, pouring sealing between the sleeves and the steel pipe piles of a pile foundation is performed with the expanded polymer, so that good sealing effect and plugging effect are achieved.
本发明属于海洋工程施工技术领域，具体涉及一种采用膨胀高聚物的水下灌注密封系统及其密封方法，包括放置于海床上的海洋设备基础、一组插接于海床上的钢管桩及一组固定配合于海洋设备基础底部四周的套筒，套筒套接于对应钢管桩外，其特征在于套筒与钢管桩之间的缝隙上下设置两个密封条，两个密封条将套筒与钢管桩之间的缝隙上下分隔为第一环形空间和第二环形空间，第二环形空间内填满膨胀高聚物，第一环形空间内浇入混凝土，使套筒与钢管桩之间固连。本发明利用膨胀高聚物进行桩基础套筒与钢管桩之间的灌注密封，具有良好的密封效果与堵漏效果。
