Geotechnical facilities
Specialized in the Geotechnical construction in the group of Euro Alliance Engineering is the company Stroyinject JSC.
Stroyinject was founded in 1960 and specializes in geotechnical engineering. In its existence of over 50 years the company has participated in the construction of all major civil and infrastructure projects in Bulgaria.
Stroyinject specializes in civil and infrastructure projects: road, railroad facilities, hydro-technical facilities, bridge foundations and strengthening of excavation pits, landslides etc.
Diaphragm walls bear with its static function the ground and water pressure and transfer them into the ground, through anchoring or ground resistance in its lower part. First of all, the excavation pit shall be made, in which guide walls are set up. They represent a kind of template for the diaphragm wall and define construction pit shape. Furthermore, they ensure correct direction of grapple and stabilize the upper read more »
Excavation pits are formed through soil excavations and where there are structures with basements, the underground floors are included. This involves all elements like walls, bottoms, strengthening and water retention. If underground water table is located beneath the lowest point of the excavation pit (excavation bottom), then the water table shall be lowered. This could be carried out by so called “water retention” read more »
Construction by the means of piles is one of the oldest methods. It is applied in soft and water saturated soil or in tide construction sites. Piles differ by their type of construction, deployment and method. According to their construction they are distinguished in single, tangent and secant piles. Reinforcement cages are prepared in advance and installed in their entire length or in sections, after which they ar read more »
The fundamental concept of soil nailing consists of reinforcing the ground by passive inclusions, closely spaced, to create in-situ a coherent gravity structure and thereby to increase the overall shear strength of soil and restrain its displacements. The basic idea consists of transferring tensile forces, generated from the inclusions into the ground through the friction, mobilized at the interfaces. IBO Self-drill read more »
This system uses a series of wells, connected to a common suction manifold. A lot of well points can be connected to just one wellpoint pump. These types of systems work well in highly variable soils and in shallow aquifers, where the water is drawn down very close to an impervious layer. Our activities: Drainages Water galleries read more »
The sheet walls could be pressed, driven by vibrations or by hammering into the ground in compliance with the local ground characteristics. Moreover, they could be installed as dense wall, in excavated in the ground diaphragm panels. Since sheet walls are executed as barriers, which are water impermeable, it is possible at their joining with cohesive soil layer or artificial dense bottom, the need of ground water tab read more »
