Embodiment

[0025] An underground water-sealed cavern construction roadway refined water storage test method, comprising the following steps:

[0026] S1. Determine the vertical height H of water storage in a single experimental section 1 and the equivalent seepage constant S under the condition of no impoundment 0 The equivalent seepage constant under the ideal working conditions and operating conditions without impoundment is S 0 ,

[0027] Order S 0 =Q(0) / (Hw-H 0 )

[0028] Among them, Q(0) is the water consumption of the main cavern before water storage in the construction roadway, Hw is the central elevation of the water curtain system section, and H0 is the central elevation of the main cavern section;

[0029] According to the water storage level H of the construction roadway in the final state op , combined with the elevation of the concrete plug and the number of proposed tests n to determine the vertical height H of the water storage for a single test 1 , H 1 =H op / n; ...

Abstract

The invention discloses a refined water storage test method for an underground water-sealed cave depot construction roadway. The method comprises the steps of: S1, determining the vertical height H1 of water storage of a single experiment section and S0 in a non-water-storage state; S2, performing testing according to the parameters determined in a preparation stage, recording values of water inflow at the beginning and ending of each test section, setting the equivalent seepage constant of any a test section as Sa, and comparing the Sa with the S0; if Sa is larger than S0, then calculating delta S/S0, and then performing grouting treatment on the area, needing to be grouted, of the test section; and if Sa is basically equal to S0, directly detecting the next test section. According to the refined water storage test method for the underground water-sealed cave depot construction roadway, scientific fine management is carried out on the water storage stage of the roadway, a seepage channel between the construction roadway and a main cavern can be recognized in the water storage process under the condition that no extra working procedure is added, and the mode of detecting and treating at the same time is adopted, so that the construction period is shortened as much as possible, and financial resources are saved as much as possible.

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 ...
