摘要
导管架封隔器主要用于将导管或裙桩套管与桩外表面之间的空间部分和海水隔绝,以保证打完桩灌浆时不使泥浆通过桩和导管或裙桩套管的接触而流入海底。封隔器通常以膨胀式为多,而膨胀式又有机械膨胀和充气膨胀两种,深水导管架又以后者居多。即将安装在惠州油区。
The paper represents the pressure test method used for the jacket sealing compartment at its prefabrication site. Based on the test of two sorts of compartment, it was determined that the rubber components of the compartment expanded normally under 250 PSIG without any leaking, thus demonstrating the efficiency and simplicity of the method.
