Specialize in hard bones! Qingdao pile base ring This dual-power head multi-function rig is on fire!

"A total of 174 piles will be hit, the pile depth is 24 meters, and the construction period is about three months!"

Yang Xiaoqing gave an understatement to the parking lot and supporting projects of the Qingdao Central Business District under construction. This project is located in the prosperous district of Qingdao. It is not allowed to be constructed at night. It will take 2 hours to rest at noon. The construction period, which was not long, was further compressed. In addition, the construction environment is complicated and the geology is hard, so many construction teams are discouraged. However, in Yang Xiaoqing's view, the difficulty is actually not big.

"Because we use equipment to force!" Yang Xiaoqing pointed at a device that was piling not far away and said with a smile.

It is a Shanhe intelligent dual-power head multi-function drilling rig, which was purchased by the Northeast Geotechnical Investigation Corporation in August 2016. Yang Xiaoqing is the person in charge of this equipment. In the past three years, he took this equipment to Qingdao. Major key projects have left a lot of "hard bones".

Yang Xiaoqing still clearly remembers the first project after the equipment was bought back. The Qingdao Blue Silicon Valley 08 section beat the station to maintain the bite pile. The project is next to the river, and the ground is filled with quicksand and silt. The construction conditions are very complicated.

"We have two rotary drilling drills before we enter the site. Because it is easy to shrink the holes, we must follow up with all the casings. Sometimes the casings can't be pulled out, and the efficiency is extremely low. Only 7 piles are hit in a month. This is not yet It is said that the average per hole exceeds six or seven square meters of concrete, so the cost has increased a lot, so the construction party is very dissatisfied."

"Our equipment can be used to get 10 piles at a time, and it effectively controls the problem of Super, and the cost is reduced a lot."

The debut of the first appearance was a blockbuster. This Shanhe intelligent double-powered multi-function drilling rig started in the pile foundation of Qingdao, and soon there were more "difficulties" to find the door! For example, in the rail-discharge well project of Metro Line 1 in 2017, this equipment only took more than 100 piles in more than one month; two stations on Metro Line 4, this equipment was played 200 times in a short time. Root pile.

Several unexpected and high-performance performances, let Yang Xiaoqing and his Shanhe intelligent dual-power head multi-function drilling rig become the “red star” of Qingdao pile-based circle. At the same time, it also appeared in more difficult situations like “firefighters”. In front of the project.

"One time I played hard rock, it was to flatten a mountain, hit it down from the root of the mountain, go to the rock, and do not drill it. There is a brand new imported rotary digging, and a pile is used. Days. After we have passed, a pile will be up to 5 hours, and an average of only 3 hours will succeed."

Looking back at the construction situation in the past three years, Yang Xiaoqing summed up a series of construction advantages of Shanhe intelligent dual-power head powerful multi-functional drilling rig: “soft and hard”, high construction efficiency, casing wall protection, no chemical mud pollution, flexible and diverse work methods. “It is an efficient and environmentally friendly new high-end pile machinery and new technology.”

It is understood that the Shanhe intelligent dual-power head powerful multi-function drilling rig is composed of a detachable dual-power head, a high-stability track-type pile frame and an advanced hydraulic electric control system, and is equipped with a combination drill such as a casing spiral drill pipe and a down-the-hole hammer. It can be used for multi-functional and multi-purpose construction, especially to overcome the serious pollution of the mud to the environment and fill the domestic technical gap.

According to Yang Xiaoqing, the Northeast Geotechnical Investigation Corporation has used Shanhe Intelligence to replace the original imported equipment since 2007. Today, in addition to this dual-powered powerful multi-purpose rig, the company has three Shanhe intelligent rotary drilling rigs and a hydraulic static pile driver that are being put into use in projects across the country.

“This dual-powered multi-function rig has been in Qingdao since its purchase. It has basically been idle for three years, so the application prospects are still very broad. In the future, if the situation continues to be hot, the company may When we set up a branch in Qingdao, we will definitely purchase more equipment. Our cooperation with Shanhe Intelligent will surely be deeper. The two sides will work together to achieve even greater breakthroughs!"
