Rotary excavation construction | Rain and sewage diversion reconstruction and sewage interception branch pipe construction project in the main urban area of Naxi
2023.10.25
Construction time
October 2023
Construction site
Luzhou City, Sichuan Province
The type of project
Municipal utilities
Device type
Piling machinery
Project Location:Luzhou City, Sichuan Province
Device Model:SR435S
Pile diameter:1000mm
Pile Depth:25m
Geology:0~6m backfill
6~20m pebbles, stones
20~25m sandy mudstone
Construction technology:A full set of pipe construction technology
Construction Efficiency:In view of the holes that are easy to collapse in the backfill and pebble layer, a full set of pipe construction is adopted, the rotary excavation power head is equipped with a casing driver, and the casing is followed up 20m under the casing, and the unstable backfill, pebbles and stone formations are traversed, and the lower part is made into a hole by picking sand bucket at one time;
Including casing, soil extraction, and rock entry, the whole hole forming time is about 6h.
