In 2014 nine the government of Mauritius highway bureau leading bureau "to connect Ripailles Verdun Teri Roger highway landslide treatment project, the project aims to alleviate the pressure of the domestic highway, especially serious traffic congestion around the capital of Port Louis.
The pile foundation construction geological condition is extremely complex, the construction platform is also very narrow, each pile hole geological condition has the difference, the construction difficulty is big, to the construction equipment climbing ability, the anti overturning ability and the overall construction efficiency request extremely high.
From the geological conditions, the surface within 5 meters for alkaline backfill (water is scattered, not water) and entrainment of more than one meter diameter or length of the floating stone, after 3 meters water depth of the silt layer and is accompanied by severe flooding (artesian water circulation and moisture are 8 meters). Start with 3 to 5 meters thick magmatic rock (weathered basalt belongs to 13 meters), there is a layer of 1.5 m thickness of ancient lava rock (breccia) or floating layer. Due to the need for slope construction, the equipment can only move back and forth on a narrow slope less than 6 meters wide, stagger the pile position construction, and the available site is extremely limited.
In the face of complicated geological conditions and construction conditions, the construction of contractors is concentrated in the fields of dams, hydropower stations, highways and so on. The construction of rotary digging pile foundation involves little and has limited experience.
In addition to Mauritius Island lack of supplies and short construction cycle, as field service personnel and the company headquarters and intelligent emergency linkage, timely adjustment of operation mode, take the segmental construction and depth of casing and other methods, customized solutions to complete construction, with the company of rotary drilling rig hard product performance and long-term accumulation in the infrastructure construction field, finally to overcome the difficulties in construction, to speed up half an hour into the rock / m speed, not to the admission 60 days has completed more than 120 stake in the period of construction conditions, will be completed in advance before the scheduled date.
Under the bad construction conditions, Sunward Intelligent rotary drilling drill has been highly praised by the construction side by virtue of the advantages of product performance and superb on-site service technology. The advantages of rotary drilling rig in China are further demonstrated, and the economic exchanges between the two countries are promoted.
