| Abstract: | In order to improve the bearing capacity of foundations,some new grouting methods and techniques have been employed in the consolidation grouting of backfilled sand-cobble stratum,including casing drilling,filling sand in a perforated pipe,protecting the wall with SM plant glue,forming a hole by diamond drilling and grouting in stages.The construction practice shows that consolidation grouting in backfilled sand-cobble stratum can meet the requirements of design and enable the diversion wall to remain stable. |
