"The cost savings are several million. This rotary drilling is my cash cow!"

A few days ago, in Shandong Lunan high-speed rail - Qufu Nishan section, Shanhe intelligent SWDM360H type rotary drilling rig hit another record - rotary power shovel under its own head, diameter 1.4 meters, depth of 50 meters. The geology of the project is very complex. The pile diameter is 1.25 meters and the deepest is 78 meters. 0-40 meters are mostly medium sand, silty clay, and 40-80 meters are limestone. More than 40 meters to 50 meters are caves, and 50 meters are more wide in diameter than 6 meters. The casing must be down to 50 meters to ensure the quality and cost of the pile.

Shanhe Intelligent SWDM360H Rotary Drilling Rig Sets New Record

The construction of the project, Hou Hou, has more than 20 years of experience in basic construction. Upon receiving this project, the construction party had a domestic well-known brand 460 rotary drilling rig with a full rotary drilling rig under construction, with an average of 96 hours per pile.

The construction progress of the project was tense. Hou decided to purchase one more equipment. After a comprehensive inspection, the intelligent drive based on Shanhe can install the casing driver. The rotary drilling rig can take advantage of its own casing to purchase the SWDM 360H rotary drilling.

The construction of the SWDM360H approaching the field exceeded many people's expectations. The first piled 50-meter-thicker casing was successfully installed only in 13 hours, and the efficiency was faster than the casing under the full-rotary drilling rig. The next full pile hole and infusion were also very smooth. The first pile was successfully piled in only four days, far exceeding the efficiency of a certain brand 460 rotary drilling rig constructed with the full-slewing drilling rig on the same site. One machine is more efficient than the two machines. Hou always laughs with a smile: “The cost savings are several million, and the efficiency is much higher. This SWDM 360H is my cash cow!”

In the subsequent construction, Hou Zong’s construction team became more and more skilled and understanding, and the progress was faster and faster. At present, it has been stable for three days into a pile. After inspection by the supervisor, the pile forming quality is very good.

It is reported that, Shanhe intelligent SWDM full range of rotary drilling rigs have the function of the machine under the casing, casing driver is a special combination of Sanhe. In Turkey and other international markets, SWDM22 and SWDM25 have all succeeded in the rotary undercutting of the machine and have created more value for customers.
