In order to solve the technical problem, a pipe twisting machine is adopted, the machine rotates a protective cylinder by using the pipe twisting machine, and presses the protective cylinder while rotating, so that the protective cylinder is easier to press to the bottom of a formed hole; but for the stratum with thicker continuous soil layer and higher water content, the resistance is very large; for example, the current pipe rolling machine has a leveling device and a pipe rolling machine with the leveling device as disclosed in chinese patent application No. 202120764975.7, and it is described in paragraph 0035 of the specification of the patent application that "the upper and lower ends of the lift cylinder 2 are hinged and connected by a pin shaft, and when the pipe rolling work is performed, the lift cylinder 2 can be adjusted to a freely telescopic oil passing state, thereby ensuring that the lift cylinder 2 is not damaged by an excessive stress. ", it can be seen that the tube-rolling machine is not rolling while pressing; moreover, as disclosed in chinese patent application No. 202120038343.2, the paragraph 0032 of the specification describes that "an installation base 371 is fixed on the side walls of a first clamping shoe 341 and a second clamping shoe 342, and a pressing and poking cylinder 372 is installed at the bottom of the installation base 371, wherein a matching groove 373 is respectively formed at the top of the first clamping base 362 and the top of the second clamping base 363, a matching block 374 is slidably connected in the matching groove 373, and the top of the matching block 374 is connected to the output end of the pressing and poking cylinder 372, so that the matching of the pressing and poking cylinder 372 and the first cylinder 331 and the second cylinder 332 does not generate the" lift cylinder of the tube twisting machine ", and thus the patent document does not adopt edge pressing and twisting; in addition, even if the lifting oil cylinder is used for pressing and twisting, the common pipe twisting machine still has the problem of insufficient pressing force for the construction of the drilling protective cylinder requiring larger pressing force.
