Method for identifying concentrated leakage section of underground water-sealed cave depot construction roadway

Abstract

The invention relates to the technical field of civil engineering, and discloses a method for identifying a concentrated leakage section of an underground water-sealed cave depot construction roadway.The method for identifying a concentrated leakage section of an underground water-sealed cave depot construction roadway comprises: judging the leakage condition of the construction roadway accordingto the actually measured water seepage quantity and the simulated water seepage quantity of the main cavern; establishing a concentrated leakage section judgment standard of the construction roadway;performing seepage segment grading, realizing the identification of the concentrated leakage section of the construction roadway. The centralized leakage section is subjected to grouting plugging andother measures. The water seepage amount of the main cavern is effectively controlled. The risk of the underground cave depot in the construction and operation period is reduced. The problem that theconcentrated leakage section of the construction roadway is difficult to accurately identify is solved. By the adoption of the method for detecting the leakage condition of each section in the subsection mode after the construction roadway is filled with water, the leakage section of the construction roadway can be detected, meanwhile, engineering cost is saved, and at present, no precedent for identifying leakage through water filling of the construction roadway exists.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a method for identifying a concentrated seepage section of an underground water-sealed cavern construction roadway. Background technique [0002] The underground water-sealed cavern is a large-scale crude oil storage method with the characteristics of safety, environmental protection, saving cultivated land, and long service life. The construction roadway is an important part of the underground water-sealed cavern. During the excavation process of the cavern, the construction roadway of the underground water-sealed cavern is the access channel for mechanical equipment personnel. During the operation of the cavern, a certain level of clean water is usually stored to ensure that the tunnel The airtightness of the library. The main chamber of the underground water-sealed cavern has certain requirements on the amount of water seepage. The water seepage from the constructio...

Problems solved by technology

[0003] The leakage of the construction roadway is mainly closely related to the integrity of the rock mass. The existing detection methods have the following disadvantages: high detection cost, long detection cycle, certain uncertainty in geophysical interpretation, and cannot guarantee the backward direction of water storage in the construction roadway. The amount of seepage water in the main cavern meets the water seepage standard of the main cavern
