Bored Pile Construction

Double Deck Mud Cleaner

Bored pile is widely used in massive civil infrastructure and industrial construction such as the tall building or bridge work. Less disturbance surrounding soil, little noise and  much economic drilling than the conventional drilling are the main advantages of bored pile. However, drilling engineers have to do mud investigation and decide which drilling technology has to be carried on. Piling contractors decide the correct drilling technology and solids control equipment minimize influence on the environment and reduce the cost.

GN double deck shale shaker with hydrocyclone is  perfect solids control system matching with the bored pile. The working function will be introduced below


drilling mud is pumped to bottom deck (2) shaker screen separate large particle to disposal site and fluid penetrate to mud tank(3), the slurry pump(4) will transfer drilling fluid to desander cone(5) for further separation. The solids/sand will be separated on the top deck (6) to discharge. The cleaning fluid will store in tank (7)

It is a compact and economic design. The smart solids control system  wins massive compliments from our clients. Please contact with us if you need more information.

Experionced in small system, GN Solids Control have high reputation in HDD & CBM field, a lot of big HDD contractors are cooperating with GN. And GN have exported about 30 small system to Australia, 15 mud system to India, 8 system to Thailand, 6 system to Malaysia, and also some other business all around the world. Now GN designed a 180m3 compact system for Sri Lanka client.piling desanding unit

GN180 desanding plant designed for cleaning drilling muds used for slurry shield tunnelling, directional drilling, diaphragm walling and bentonite piling.

Desanding plants are employed to remove soil partcles in drilling muds and support slurries used in foundation engineering. They can be either water-bentonite, water-polymere, or water-cement and bentonite suspensions. Desan-ding plants have further applications in gravel pits, in the mining industry and in microtunneling projects.
The regeneration or cleaning capacity of a desanding plant is determined by the plant´s intake capacity of contaminated suspension.

This GN180contains 1 high efficient double deck linear motion shale shaker GNZS703D, c/w 2ea 10inch hydrocyclones, after treated by the bottom deck shaker screen, the drilling mud pumped to the cylone by a horizontal slurry pump.

System specially designed for container loading tanks & equipment, and easy operating, just put the shaker on top, and connect the necessery pipeline, then start.

For more information on process, pls refere to piling unit to Pakistan.
