Low headroom construction case | Huanggang Qichun Power Grid Project

Customer unit: Hubei Boyue Construction Engineering Co., Ltd

Project introduction: The construction site is in the mountainous area, the road traffic is inconvenient, and the large-scale rotary digging equipment cannot be entered, due to the height limitation of the high-voltage line on the site, the need for low clearance to customize the rotary digging, and can be transported with rods, and the transfer is convenient and fast.

Construction equipment: low headroom 12.9m-SR175S

Construction geology: 0~8 meters of soil layer, 8~16 meters of strong weathered mudstone and sandstone

Pile diameter: Φ1.2m

Pile depth: 16m

Drill pipe: standard machine lock drill pipe Φ377mm×4×8.4

Drill bucket: Φ1.2m sand bucket

Project Description: Huanggang City Qichun Power Grid Pile Foundation Tower, the construction site is relatively scattered, from one hilltop to another mountaintop.

Construction difficulties: Huanggang Qichun power grid tower foundation pile on the mountain, large-scale rotary digging into the field is inconvenient, a base only four piles, need to be frequently transferred.

Problem solving: Our 175S is transported with a rod, which perfectly fits the characteristics of frequent transitions, and it is convenient and fast to enter and exit the site.
