Top-Down Construction Method

Top-Down Construction MethodTop-down method is a rapid method which enables builders to construct the substructure and superstructure simultaneously. Likewise it is used as an excavation stabilization method in cases where you can’t or you are not allowed to use the other geotechnical methods such as soil nailing and soil anchorage.

Soil Anchorage

Soil Anchorage

Soil anchorage is an active method for stabilizing inclined lands and excavations. In this method soil wall is drilled up to 20 cm and to enough depth, then preassemble steel reinforcement is placed in the drilled hole and the cement bass grout is injected in the hole. Then it is activated by prestressing hydraulic jacks to stabilize the excavation and incline lands.

Deep Soil Mixing

Deep Soil Mixing

Deep soil mixing (DSM) is a method in which the soil is mechanically mixed with adhesive binders to increase the strength and bearing capacity of under laying soil to the desired depth. Depending on the soil and water table situation the wet or dry methods are applicable.

Choosing correct and effective solutions usually need a great experience in this field. Although considering the available techniques would lead to certain solutions, but wrong solutions may result in disaster. After choosing the right solutions, next step will be utilizing the proper and patented software to design the details and compare the feasible techniques.
