[0025] The working principle of the device to solve the problems of existing steel flower pipe soil nailing construction equipment and high labor costs is as follows: since the excavator is an essential engineering equipment in foundation construction, and the excavator bucket can also be replaced by a structure with other functions (such as a punch for demolition), on this basis, the excavator punch 6 is fixedly sleeved with the casing 1 through a tensioning mechanism, and the expansion inner casing 201 is pushed relative to the expansion outer casing 2 by screwing in the spinning tube 202, and the expansion inner casing 201 is contracted and sleeved tightly with the excavator punch 6 by using the conical surface, so as to reduce the pressure of the baffle 103 and prevent the baffle 103 from being damaged during the impact, and the positioning head 106 is connected with the casing 1. The steel pipe soil nails are inserted and driven into the ground using an excavator and an excavator punch 6. The specific structure of the tensioning mechanism is as follows: an expansion outer sleeve 2 is sleeved inside the sleeve 1, the inner wall of the expansion outer sleeve 2 is conical, and the wide end of the expansion outer sleeve 2 is away from the steel pipe soil nails. An expansion inner sleeve 201 is sleeved inside the expansion outer sleeve 2, the outer wall of the expansion inner sleeve 201 is fitted with the expansion outer sleeve 2, and grooves are evenly opened on the circumferential walls at both ends of the expansion inner sleeve 201.
