Description

Construction machine and method for controlling a construction machine Technical Field The present invention relates to a construction machine to which a foundation work tool in the form of a hydraulic or cable grab is attached or will be attached, and to a method for controlling such a construction machine. Background In performing civil engineering or other excavation operations, such as the construction of foundation elements, such as foundation piles or diaphragm walls, a foundation work tool, particularly in the form of a hydraulic or cable grab, is attached to or will be attached to the construction machine for performing the operation, the specific control of which depends on the nature of the geological conditions of the constructed foundation. Thus, a ground profile (ground profile) is usually created for the construction foundation in each case, at least for larger construction projects. The foundation profile indicates the structure (in particular, the stratiform structure) of a different type of foundation from other types of foundations in terms of the composition of the foundation material (in particular, with respect to its physical properties). For example, a foundation profile is created by means of pilot drilling in order to determine the foundation profile of the constructed foundation based on the obtained drill core. From an economic point of view, it is important to know the foundation profile of the constructed foundation, as the structure of the foundation determines how much the cost of foundation excavation will be. For example, excavating a construction foundation containing a significant amount of rock material is more complex than constructing a foundation containing sand, gravel and/or clay layers because the rate of advance is lower and the tool wear is higher. However, depending on the geological conditions of the constructed foundation, the foundation profile may also fluctuate greatly in locally limited areas. These fluctuations typically include variations in the thickness of the individual strata and may also include variations in the rock interface (rock horizon). In the present invention, it is assumed that physical properties of the foundation (such as hardness, density, waviness, cohesiveness, etc.) vary from formation to formation. This has the consequence that certain machine parameters to be applied to the construction machine for machining a construction task have to be adjusted and that appropriate values have to be selected in order to optimize the machining of the corresponding soil layer. Up to now, these adjustments have to be performed manually for each individual parameter. This is time consuming because the actuating means for the foundation work tool attached or to be attached to the construction machine, by means of which the foundation work tool can be inserted into the foundation to be worked, has a wide range of adjustment options and requires the operator to have proper expertise and extensive experience in order to be able to make the best possible adjustment. While there are auxiliary systems in construction machine control systems that alleviate the burden of the machine operator and enable faster adjustment and control processes by automating monotonic or repetitive operations through programs with predefined steps, some machining operations are not fully automated and still require the machine operator to make decisions. This involves in particular gripping aids (for hydraulic or cable grab). Here, different parameters may need to be selected or applied for individual formations. Such machine parameters used by the control means of the construction machine to control the actuating means in order to control the machining operation at the actuating means include, for example, the lowering height of the foundation work tool, the closing cycle of the grapple shells, the closing force of the grapple shells, the closing speed of the grapple shells, the filling degree of the grapple shells, the repetition of the closing cycle or lowering in the case of foundation work tools such as hydraulic or cable grapples (which may in particular be drilling grapples, diaphragm wall grapples, or pile grapples). Disclosure of Invention The object of the present invention is to provide a construction machine to which a foundation work tool in the form of a hydraulic or cable grab is attached or to which it is to be attached, and a method of controlling such a construction machine, by means of which the complexity of selecting and adjusting the working parameters is reduced and a higher working efficiency can be achieved. According to the invention, this object is achieved by a construction machine having the features of claim 1 and a method having the features of claim 10. Preferred embodiments of the invention are provided in the respective dependent claims. The construction machine according to the invention, in particular in the form of a hydraulic or cable grab,
