穿河流装 MPP 电力管咋钻孔?水下密封技巧​

2025-09-29

在穿河流安装MPP电力管时,钻孔环节至关重要。首先要选择合适的钻孔设备,确保其具备足够的动力和精度以应对水下复杂环境。钻孔前需对河床地质进行详细勘察,根据不同土质调整钻孔参数。在钻孔过程中,要保持匀速推进,避免因速度过快导致孔壁坍塌。

而水下密封更是关键一步。可采用专用的密封材料,如高性能橡胶密封圈等。安装时要确保密封材料与管道及河床接触紧密,无空隙。密封完成后,需进行水压测试,检查密封效果。只有掌握好钻孔和水下密封技巧,才能保证MPP电力管在穿河流安装后的长期稳定运行,为电力传输提供可靠保障。同时,施工人员要严格遵守操作规程,确保施工安全。
