In September 2015, our company undertook Chongqing Qianjiang Apeng River Railway Bridge from 0# to 19# piers (including 13# auxiliary piers, 14# and 15# main bridge piers, 16# auxiliary piers with a diameter of 2800mm, (L=65~98m rock-socketed piles included) All bridge pier pile foundation construction tasks) This is the 15# main pier construction scene.

On March 18, 2015, the rock-socketed piles (210 pieces) of the Yangshan Phase IV Wharf were drilled. As of October 5 of the same year, 76 pieces of φ2.3m and 126 pieces of φ2.5m were completed, and the remaining 8 independent mooring piers were Φ2. 0m rock-socketed pile is under construction.

In March 2016, our company undertook the construction of rock-socketed piles (including straight piles and inclined piles) of my country's first (the world's largest single-machine capacity) 3.4 MW "tidal power assembly platform" pile foundation (including straight piles and inclined piles) in China near Zhoushan-Xiushan Island. In this project, we overcome natural conditions such as rapids (-5m per second) and whirlpools, and successfully carried out accurate and correct construction on the weathered bare rock in the seabed.

This is the scene of our company's 5 rotary drilling rigs at the construction site of the non-navigable hole pier rock-socketed piles on the east artificial island of the Hong Kong-Zhuhai-Macao Bridge to the Lantau Island side of Hong Kong

The 14# main pier of Chongqing Apeng River Railway Bridge, like the 15# main pier, is a pile foundation construction group composed of 36 rock-socketed piles with a diameter of 2800mm and a length of 86~98m. Photo-On the hillside behind it is the 0#~13# pier pile foundation construction area, and in front of it is the beautiful "Apeng River"

The 14# main pier of the Chongqing Qianjiang Apengjiang Railway Bridge. In this small construction area, our company invested one SR385 rotary excavator and 9 10-16 ton percussion drills to construct 36 piers with a diameter of 2800mm and a pile length of 86m~98m. Rock-socketed pile construction. In order to solve the construction of the super-long piles of the 14# and 15# main bridge piers, our company has adopted the combined construction technology of rotary excavator + percussion drilling rig after the demonstration of quality, safety and economy.
