The "Trinidad and Tobago aid project" under the responsibility of Shanghai Construction Engineering Group Overseas Department is divided into three major engineering parts: the cycling track, the National Swimming Training Center and the Kuwa National Children's Hospital. Among them, the pile foundation project has a total of more than 4,000 cast-in-place piles, with a total project cost of 10 million yuan.

 

The project pile depth ranges from 12 meters to 20 meters, and the pile diameter is 600mm. The geological conditions on the construction site of a bicycle racing track are complicated, and the sand layer is 6-8 meters high, which is very difficult to hit. The geological conditions of the latter two construction sites have improved significantly. When working for 6-7 hours a day, the number of holes formed by the two cars reaches 40. While reducing the working time, the number of holes formed per day has nearly doubled. The stable construction efficiency and convenient maintenance features of the drilling rig have been unanimously recognized by domestic and foreign workers; the leaders of Shanghai Construction Engineering and Shanghai Yuneng Construction Company have high evaluations of the KR125 drilling rig, and the good performance and construction efficiency of the drilling rig exceed The construction target expected by Shanghai Construction Engineering was established.
