Grouting method by the whole surface waterproof manner for imperviousness of retaining wall

摘要

The present invention is to provide a water resistant front grouting method for the degree of toryubyeok to improve the safety and workability to fix the leaks through the front water grouting.; Front resistant grouting method for the degree of toryubyeok according to the present invention, in CIP, Ltd., SCW, Ltd., carrying out the SW, Ltd., etc. In order to excavate the ground for the construction of underground structures, and preventing the collapse of the gravel, dagger weaving of pile If the gap due to a leak in the grouting method for preventing it, confirming and setting the leak site due to the spacing between the piles, such as CIP; Establishing a specific leakage and leakage state, leakage area, In the plan of action method for grouting investigate the types of soil and various types of equipment and required thing; After removal of the foreign matter of the leak portion between pile, after sealing in the region of the peg from jesal steps of: installing an injection port; After creating the pre-blended mixture of the materials according to the compounding ratio designed grouting material, injecting and determining the final end of the injection the mixed grouting material through the injection port; And plan excavated surface or less after subjected to front water leaks when grouting to a predetermined depth, with the backfill comprises the steps to complete a task.
