A refined water storage test method for construction roadways of underground water-sealed caverns

Abstract

The invention discloses a refined water storage test method for underground water-sealed cavern construction roadway, including S1, determining the vertical height H1 of water storage in a single test section and S in the state of no water storage 0 ; S2, carry out the test according to each parameter determined in the preparation stage and record the value of water inflow at the beginning and end of each test section, the equivalent seepage constant of any a test section is Sa, compare S a and S 0 size; if S a >S 0 , and then calculate ΔS / S 0 , and then perform grouting treatment on the area that needs to be grouted in the test section; if S a with S 0 If they are basically equal, the next test segment can be detected directly. The refined water storage test method of the construction roadway of the underground water-sealed cavern of the present invention performs scientific and refined management on the water storage stage of the construction roadway, and can identify the construction roadway and the main cavern during the water storage process without adding additional procedures In order to shorten the construction period as much as possible and save financial resources, we adopt the method of monitoring and treatment at the same time.

Description

technical field [0001] The invention relates to a refined water storage test method for construction roadways of underground water-sealed caverns. Background technique [0002] Underground water-sealed caverns have the advantages of safety, environmental protection, environmental friendliness, and low cost, and are currently being vigorously promoted in my country as an oil storage method. Before the underground water-sealed cavern enters the oil storage state, it is necessary to store water to a certain height in the construction roadway to ensure the airtightness of the cavern. [0003] Underground water-sealed caverns are often built in hard rock mass. The cracks in the rock mass are very complex, and there may be seepage channels between the construction roadway and the main cavern. If there are seepage channels, on the one hand, it will increase the water inflow in the cavern, resulting in an increase in operating costs; on the other hand, it will affect the long-term ...
