cofferdam construction

MW350 water well drilling rig is widely applied in the hole drilling of water wells, geothermal wells and so on. It can operate under different complicated geological conditions, with a larger drilling diameter. The unique longhole axial compression control system can adjust the propulsion reasonably, reducing the steering resistance of deep well drilling. The two-stage telescopic carriage enables the use of a 6m drill pipe, greatly reducing the times of pipe extension. Besides, the overhead drive head comes with a large spindle diameter, making the drilling rig suitable for the drilling of mud, air and foam to satisfy the requirements of different geological conditions.

A steel casing pipe or tube used in drilling well or any underground installation is called casing tube or pipe. Steel Casing Pipe, also known as encasement pipe, is most commonly used in underground construction to protect utility lines of various types from getting damaged.

The cofferdam project is a large-aperture pile hole construction plan. 1000mm and 1200mm diameter casings need to be inserted into the rock formation for 5-6 meters, the total depth of the pile holes is 25-30 meters, 300 piles with a diameter of 1200mm, and 280 piles with a diameter of 1000mm. This solution is expected to allow the port to obtain a load capacity of 500,000 tons, thereby increasing the throughput of the Chulai port.

D Miningwell DTH hammer adopts advanced drilling theory design, which enables our DTH hammer to obtain good energy transmission, fast drilling speed and low air consumption. The raw materials are of good quality, the processing technology is advanced, the performance is stable, and the service life is long. Easy to use, easy to install and remove, easy to service, easy to service.

Casing pipes are used for casing oil & gas wells. In casing a large diameter pipe is assembled and is inserted into a drilled section of a bore-hole.
