A comprehensive treatment method for underground engineering lining seepage water

Abstract

The invention discloses an underground construction tunnel lining water leakage comprehensive treatment method. The method comprises the steps that a water source is searched for through a geophysicalprospecting method and holes are drilled within a certain range on the two sides of a water leakage area to relieve pressure; systemic drilling and grouting are conducted in the water leakage area and the grouting sequence is implemented from the middle to the two sides of a water source area; emphasized and targeted treatment is conducted within a period of time after completion of system grouting and drilling and grouting are conducted on a water leakage point area in the remaining water leakage area; lining deformation serves as master control, and quantity pressing is combined as secondary control; the purposes of no obvious water leakage points, most of the area being the dry no-water surface and water seepage occurring to a small part of area can be achieved within a period of timeafter completion of drilling and grouting; after emphasized treatment for a period of time, supplementary reinforcement and treatment are conducted and grouting is conducted on the lining surface water leakage area; according to the standard of grouting completion, lining deformation serves as master control, and quantity pressing is combined as secondary control; after completion of grouting treatment, the lining surface starts to be cleaned, and the lining surface is restored.

Description

technical field [0001] The invention relates to a comprehensive treatment method for lining seepage water, which is especially suitable for treating lining seepage water in underground engineering. Background technique [0002] With the rapid development of the national economy, urban rail transit and large underground shopping malls have also entered a period of rapid rise. The quality of underground engineering is an important key to its function, and the leakage of underground engineering is an important factor that seriously affects the construction quality of underground engineering and threatens the normal operation of underground engineering. Therefore, the problem of water leakage in underground engineering is a key problem to be solved urgently. Due to the lack of systematicness and pertinence, traditional governance methods will inevitably fall into a vicious cycle of leaking one place and treating one place, and then leaking and re-treating, making it difficult t...
