Product Description
Rotary drilling is a construction technique suitable for drilling operations in building foundation engineering. Widely used in foundation construction projects such as municipal construction, highway bridges, and high-rise buildings, with different drilling tools, suitable for drilling operations in dry (short spiral), wet (rotary bucket), and rock formations (core drilling).
(1) Before starting construction, the site engineering geological data and necessary hydrogeological data, pile foundation engineering construction drawings, and drawing review minutes should be available.
(2) Survey data on underground pipelines (pipes, cables), underground structures, hazardous buildings, precision instrument workshops, etc. within the site and adjacent areas.
(3) Technical performance data of the main construction machinery and its supporting equipment, inspection and mix ratio testing of required materials, physical property testing of required materials must be conducted, and qualified laboratories must be commissioned to conduct concrete mix ratio testing based on the raw materials used.
(4) Effective construction organization design or construction plan for pile foundation engineering, and reference materials for load and construction technology testing.
