[0002] Civil engineering generally refers to civil engineering projects, which refer to the planning, construction and maintenance of all infrastructure related to water, soil and culture. General civil engineering projects now include: houses, roads, water services, canal services, flood control projects and transportation, etc. In the past, all non-military civil engineering projects were classified into this category, but with the increasing breadth of engineering science, many contents that originally belonged to the scope of civil engineering have become independent disciplines. Referring to Chinese patent CN111188486A: A steel structure earthquake-proof support for construction, including a support base, a positioning rod is arranged on the side of the support base, a lower buffer is fixedly connected to the upper end of the support base, a lower mounting plate is fixedly connected to the upper end of the lower buffer, a lower mounting seat is fixedly connected to the side of the lower mounting plate, a support rod is arranged on the inner side of the lower mounting seat, the upper end of the lower mounting seat and the lower end of the support rod are mutually connected through a lower connecting shaft, and an upper mounting seat is arranged on the upper end of the support rod. The vibration bracket is provided with a lower buffer and a side buffer. The buffer springs in the lower buffer and the side buffer can be used to buffer the vibration, thereby achieving common shock protection in the horizontal and vertical directions, avoiding the left and right swaying of the bracket itself due to shock absorption in the vertical direction, greatly improving the safety of construction, and ensuring the continuous progress of the construction process. This patent achieves the reduction of the vertical and horizontal vibrations of the equipment through the lower buffer and the side buffer, but the actual reduced vibration still has a great impact on the actual stability of the equipment, making the equipment unable to cooperate with the existing scaffolding equipment for a higher degree of construction. At the same time, this patented equipment can only avoid the vibration caused by the movement of construction personnel, so that the actual use of the equipment is not wide enough. Summary of the invention

The vertical vibration generated can also effectively reduce the vibration of the operation of civil engineering machinery and equipment, thereby effectively improving the practical application range of the equipment, and under the influence of the weight of the civil engineering machinery and equipment, the equipment can more stably realize its functions. At the same time, under the effective support of the first limit ring and the second limit ring, the connection between the first support rod and the second support rod can be firmly in contact with the designated work location, thereby effectively preventing the horizontal vibration from causing the positioning bolt to tilt, ensuring the stability of the actual use of the equipment, and the connecting rod can be conveniently installed and disassembled through the connecting pipe, so that the connecting rod can be firmly connected to the existing scaffolding equipment under the effective position limit of the second limit plate, thereby effectively providing a stable construction foundation for the higher erection of the existing scaffolding equipment.
