Construction Techniques for the Water Curtain System in Sealing Cave Depots of Petroleum with Underground Water

地下水封石油洞库的密闭性主要通过地下水来控制,通过水幕系统进行补充,水幕系统的作用很重要。结合惠州国储石油洞库介绍了水幕系统的的施工工艺,并对水幕孔的施工、水幕试验、水幕巷道的清底等关键技术进行了详细的阐述。水幕系统最终技术状态良好,其施工技术有借鉴意义。

The sealing performance in sealing cave depots of petroleum with underground water is chiefly controlled with under-ground water, with water curtain systems used to supplement, in which case water curtain systems have an important role to play. With the state-owned cave depot of petroleum in Huizhou as a practical example,introduced in the present paper are the construction processes for water curtain systems, with the key construction techniques such as the construction of the water curtain holes,the water curtain tests,the bottom-clearing of the water curtain shafts and the like dealt with in detail. The final technical state of the water curtain system is found to be very good. The construction techniques adopted for the project may serve as a useful reference for other similar projects.
