Tremie equipment

The tremie concrete pouring method is used for well concreting in water-logged soils as well as for concreting of building structures of any purpose where concrete delivery height (free dropout) exceeds 3 meters in order to avoid concrete mixture segregation. Standard tremie pipes diameters are 219 mm, 245 mm, and 325 mm.

Any other diameters are also manufactured on client’s request. The volume of the tremie funnel depends on well depth, its diameter, and minimal volume of the first concrete batch, as well as on displaced fluid volume; it equals 0.2 to 3 m. The tremie set includes a tremie funnel, tremie pipes with length of 1 to 6 m, a tremie holder, a lifting cap and spare parts.

Unit is a platform-mounted lifting gear. The platform is installed on the elements of the foundation pile with a crane. The unit’s two winches carry out lifting and hoisting operations. The complete UVPT 55 unit includes a rack of 12 concreting pipes 4.5 m long each, a string tip designed to prevent pipe string gripping on pile reinforcing cage elements, and a lifting link for reliable locking of tremie pipe to the winch.

Unit functionality:

• extracting tremie pipes from the rack and transferring them to the support frame for string assembly;
• sinking the pipe string into the pile;
• stabilising the string for concreting;
• lifting the string during concreting;
• dismantling the string and transferring the pipes to the rack.

Tremie pipes are handled with the lifting link. The unit is equipped with heightadjustable supports. After centering on the pile the platform must be put into horizontal position by a crane, and platform supports must be adjusted by resting them on foundation pile elements. Based on the terms of reference agreed upon with the Customer, our experts will promptly design and manufacture tremie pile concreting units of other sizes and with other design features.
