Sea area deep hole static sounding test equipment and test method thereof
The invention relates to sea area deep hole static sounding test equipment and a test method thereof, and the equipment comprises a static sounding test platform which is positioned above the water surface of a static sounding test hole site; the lead hole coring drilling machine comprises a drilling machine body located on the static sounding test platform, the drilling machine body is connected with multiple sections of double-layer sleeves which are sequentially lengthened, and the bottom of the first section of double-layer sleeve is connected with a coring bit; and the static sounding equipment comprises a hydraulic loading system located on the static sounding test platform, and the hydraulic loading system is connected with a probe rod assembly which extends into the double-layer sleeve and carries out static sounding on the static sounding test hole site. When the hole guiding coring drilling machine needs to help static sounding equipment to conduct hole guiding operation, the double-layer sleeve does not need to be pulled out, and the double-layer sleeve directly serves as a drill rod to conduct drilling on the stratum. The problem that in the prior art, multiple sleeves need to be pulled out when the multiple sleeves are repeatedly added or detached and a guide hole needs to be drilled when static sounding reaches the penetration limit is solved.
本申请涉及一种海域深孔静力触探测试设备及其测试方法，包括：静探测试平台，该静探测试平台被定位于静探测试孔位的水面以上；引孔取芯钻机，其包括位于静探测试平台上的钻机，钻机连接有多节依次接长的双层套管，首节双层套管的底部连接有取芯钻头；静力触探设备，其包括位于静探测试平台上的液压加载系统，液压加载系统连接有伸入双层套管内并对静探测试孔位进行静力触探的探杆组件。本申请当引孔取芯钻机需要帮助静力触探设备进行引孔作业时，无需拔出双层套管，而是将双层套管直接充当钻杆对地层进行钻进。本申请杜绝了相关技术中反复增加或拆卸多重套管，当静力触探达到贯入极限需要钻探引孔时，又需要拔出多重套管的问题。
