Construction of Business center: excavation pit enclosure and support.


Enclosure and temporary sup- port of excavation pit, sized 42x39 m and 6.8/5.6 m-deep, as well as consolidation of neighboring building founda- tion, were projected and in 1995 executed on the site.

Geological composition at site was as follows:

  • 2-3.5 m layer of fill up soil;

  • 8-10 m layer of fine-sized sands;

  • 5-7 m layer of hard Juras- sic clays.

    Basic technical solutions:

  • Excavation pit enclosures - in-situ reinforced concrete diaphragm walls 60 cm-thick and their area is 22752 m2 with panels key-joined based on Italian technology;

  • Temporary support - bored anchors and metal pipe struts;

  • Consolidation of foundati- ons - bored micropiles.
