What are these two machines? Engineering construction earthwork

As shown in the figure, the first type is the drilling shotcrete machine, which means that one machine can be used for both purposes. In the process of earthwork excavation, it can also be used as a dewatering well or a water stop beam, and can also be sprayed when the slope needs to be sprayed with concrete! Widely used in high-rise buildings.

Fig. 2 is a pile driver. Judging from the figure, it is mainly static pressure piles. Piling is generally used for foundation treatment of high-rise buildings. This machine is used to press a large number of precast concrete piles into the foundation to improve the bearing capacity of the foundation. I wonder if you have any questions about these machines.
