A few days ago, news came from the construction site of the MESONG Jinhui project on the Diamond Island in Cambodia. The Sunward Intelligent SWDM360H rotary drilling rig was highly recognized by the project party for its strong rock drilling ability.

The difficulty of the pile foundation construction of the Cambodian Diamond Island MESONG Jinhui Project is recognized in Cambodia. The site has a total of 189 main piles with a diameter of 1.5 meters and a depth of 73 meters to 75 meters, with an average depth of 35 meters. The geological conditions of the project are extremely complex, divided into seven geological structural layers, namely backfill-silt sand, clay-clay, silty clay-silt-clay full weathering-strong weathering (6.5Mpa)-medium differentiation (23Mpa) -Slight weathering (40Mpa), in which the slightly weathered rock formation reaches 20 meters, which is extremely challenging to the performance of the rotary drilling rig.

CITY KEY is an established company in the field of pile foundation construction in Cambodia. With its strong strength and professional ability, it has undertaken many large-scale pile foundation construction projects in Cambodia. Since the pile foundation construction of the MESONG Jinhui project on Diamond Island started in February this year, even CITY KEY has faced great pressure. The company entered the construction of the project with a total of 4 equipment, of which 2 were SWDM360H from Sunward Intelligent. Due to complex geological conditions, the performance of two other brands of rotary drilling rigs from CITY KEY was not satisfactory during the construction process. One 360R has been idled on the construction site due to its slow drilling speed (one hole per week). 460 also left the field due to poor rock entry ability. 2 Taishanhe Smart SWDM360H's performance of forming a hole in 22-26 hours became the absolute main force of the project. In the words of the client, it is "Shanhe Intelligent Rotary Drilling Rig has sufficient power, large torque and good stability!"

In order to better serve customers, Sunward Intelligent dispatched an experienced after-sales service engineer team to the construction site to provide business guidance and training to the client's hands, and promptly propose solutions when encountering construction problems. The timely supply of spare parts from Sunward's Cambodian after-sales warehouse also provides a strong guarantee for drilling work.

In August of this year, in order to make up for the delayed engineering progress of the two decommissioned equipment, CITY KEY urgently ordered a SWDM450 rotary drilling rig from Sunward Intelligent, becoming the only construction unit in Cambodia with a super torque rotary drilling rig.
