The invention relates to a method for constructing a foundation for a tower structure, comprising at least one structure-side connection profile in the form of a pipe segment. The method has the steps of providing a foundation pile with a diameter which differs from the diameter of the pipe segment, vibrating and/or ramming the foundation pile into a supporting substratum, aligning and fixing the pipe segment coaxially and concentrically to the foundation pile introduced into the substratum such that an annular space is formed between the pipe segment and the foundation pile, and filling the annular space with a curable casting compound.

The invention relates to a method for carrying out a construction measure, in particular a foundation engineering measure, with a construction device, in particular with a foundation engineering machine, which has a plurality of actuation elements and sensors for recording operating states relating to the actuation elements, and with a computer unit, by which recorded parameter values of the sensors are received when carrying out the construction measure. According to the invention provision is made in that for a construction measure a number of different defined process steps are stored, in that from one defined process step to at least one subsequent defined process step a transition takes place as a result of at least one exit rule, wherein to each exit rule at least one characteristic parameter value of at least one sensor is assigned, and in that the recorded parameter values of the sensors are checked as to the exit rules and, if they occur, a transition from an associated defined process step to a subsequent defined process step is detected.

A sonic pile driving adapter is configured to couple a drill head to a member to be pile driven. The adapter includes an upper attachment portion for selectively attaching to the drill head and a lower mounting portion. The lower mounting portion has first and second side plates configured to be inserted into the member. The first and second side plates include a first plurality of through holes corresponding to a second plurality of through holes provided on the member. The adapter also includes a plurality of brackets with a third plurality of through holes. A plurality of fasteners extends through the first, second and third pluralities of through holes, thereby coupling the sonic pile driving adapter and the drill head to the member. The adapter and method of use allow for efficient transfer of oscillating energy to the member and more effective pile driving.

A foundation treatment method for piling a foundation structure by penetrating a hardpan layer, i.e., a Deep Slurry Mixing method, comprising following steps: disturbing, by a mechanical device, a location where the foundation structure is to be piled, so that the mechanical device penetrates the hardpan layer of a natural foundation; then injecting clay slurry into the hardpan layer of the natural foundation by a pumping device, an improved foundation is formed after mixing; and piling the foundation structure. The method can change soil property of the original natural foundation, break the hardpan layer, reduce piling resistance of the steel plate cylinder or similar foundation structure, reduce uneven force during the piling process and improve driveability.
