Leakage stoppage strengthening method for vibration disturbance resistance honeycomb pitted furnace for underground engineering

Abstract

The invention discloses a plugging and reinforcement method for anti-vibration and disturbance honeycomb pitted surface used in underground engineering. Firstly, cement grouting is used to stop the water of the structure with large leakage water, and the method of pinhole grouting is used to pour low-type modification Epoxy grout, apply cement-based permeable crystalline waterproof material to the leaking parts of the tiny gaps that cannot be grouted, use concrete to squeeze water out of the cracks and pores of the secondary lining, and then use cement-based rigid anti-seepage mortar to spray or Scrape coating, and after the plugging of the root of the embedded parts is completed, slot and fill the sealant; finally, use a drilling tool to drill through the lining structure to release pressure and drain water at the serious water leakage, forming an effective new drainage blind pipe. The method of the invention can effectively tamp the uncompacted honeycomb pitted surface, thereby solving the problems of water seepage and water leakage, and has good treatment effect and high pressure.

Description

technical field [0001] The invention relates to the technical field of plugging in underground engineering, in particular to a plugging and reinforcing method for anti-vibration and disturbance honeycomb pockmarked surface in underground engineering. Background technique [0002] At present, in underground projects such as tunnels and subways, non-dense honeycomb pockmarks often appear. These honeycomb pockmarks often leak water due to their structure. High, high water content of concrete causes segregation and other factors, resulting in non-compactness and honeycomb pitting. When the external water pressure is greater than the concrete impermeability pressure here, water leakage will occur, mainly manifested as point leakage and surface leakage. And existing processing mode to honeycomb pockmarked surface is all relatively simple mode, and effect is not ideal, and the situation of water leakage still occurs. Contents of the invention [0003] The object of the present i...
