Description

Technical Field

[0001] The utility model relates to the technical field of H-shaped steel pile driving, and more specifically, to a tool for driving H-shaped steel piles in an SMW construction method. Background Art

[0002] The SMW method uses a multi-axis drilling and mixing machine to drill to a certain depth on site. At the same time, a cement-based strengthening agent is sprayed at the drill bit to repeatedly mix and stir with the foundation soil. The construction units are overlapped and then H-shaped steel or steel plates are inserted as stress reinforcement before the cement-soil mixture hardens. When the cement hardens, an H-shaped steel pile driving tool is required when driving the construction pile. For example, the SMW method disclosed in the patent technology of prior art announcement number CN218437055U The H-shaped steel pile insertion and delivery tool for the construction method pile calculates the distance that the H-shaped steel column body needs to be inserted according to the working surface elevation and the support top elevation. When the support engineering working surface is far away from the designed top elevation, the reinforced downward pressure block, reinforced downward pressure square warehouse and reinforced extension plate are put on the top of the H-shaped steel column body through the frame mouth according to the insertion distance, so that the H-shaped steel column body can extend into the placement groove, and then the reinforced connecting plate is pressurized by external mechanical equipment, so that the H-shaped steel column body can be inserted to the specified position and then pulled out.

[0003] When the above device is in use, the overall design is simple and the structure is reasonable. The reinforced downward pressure block, the reinforced downward pressure square bin and the reinforced extension plate are put on the top of the H-shaped steel column body through the frame mouth, which is more convenient to use. However, it is more inconvenient to install it at one end of the construction pile. At the same time, the stability of the connection between the pile delivery tool body and the construction pile is poor. Utility Model Content
