Anti-falling grounding fastening pile

Abstract

The invention belongs to the technical field of power grid protection fixed structures, and particularly relates to an anti-falling grounding fastening pile. The anti-falling grounding fastening pilecomprises a mounting cylinder, a self-recovery assembly and a self-filling assembly, wherein the self-recovery assembly and the self-filling assembly are arranged in the mounting cylinder; the mounting cylinder comprises a cylinder body and an inverted-cone-shaped cylinder bottom at the bottom; the self-recovery assembly comprises a fixed end cover, a connecting rod, a compression spring and a buffer piece; the self-filling assembly comprises a ratchet rod, a pressure-resistant cylinder assembly, a ratchet positioning assembly and a pressure control assembly; and the pressure control assemblycomprises an upper piston and a pressure control piece. The anti-falling grounding fastening pile has the advantages of convenience in installation and use and less later-period maintenance operation,and in the using process, after soil around the fastening pile is lost, adhesive force is reduced and the fastening pile is loosened and moves upwards, pores, holes and the like outside the fasteningpile can be filled with foam materials, so that the phenomenon that soil in the holes collapses and falls off is restrained, the phenomenon of soil loss is slowed down and avoided, the fastening effect and long-term stability of the fastening pile are effectively increased, and the use and maintenance cost of the basic fastening pile can be reduced.

Description

technical field [0001] The invention belongs to the technical field of power grid protection and fixing structures, and in particular relates to a detachment-preventing grounding fastening pile. Background technique [0002] Grounding fastening piles are basic equipment often used in the process of power grid construction. They are mainly used for reinforcement and grounding of various poles, towers and other devices. The functional structures of fastening piles are various, except for a few If the construction is pre-buried in advance during the construction process, most of the fastening piles need to be temporarily configured and used according to the needs in the construction or maintenance process. According to the basic purpose of the fastening piles, we hope that they can be stably connected and fixed at the preset position for a long time.

[0002] Grounding fastening piles are basic equipment often used in the process of power grid construction. They are mainly used for reinforcement and grounding of various poles, towers and other devices. The functional structures of fastening piles are various, except for a few If the construction is pre-buried in advance during the construction process, most of the fastening piles need to be temporarily configured and used according to the needs in the construction or maintenance process. According to the basic purpose of the fastening piles, we hope that they can be stably connected and fixed at the preset position for a long time. In the process of on-site construction, it can be effectively fixed by connecting and fixing it on the stable foundation of the ground or by pouring cement. However, this kind of solution is time-consuming and labor-intensive, and is generally only used in large and medium-sized area construction operations. For scattered The transmission network infrastructure distributed in urban and rural areas and mountainous areas often does not have the corresponding conditions. In the above-mentioned areas, when installing the fixed piles, it is generally smart to carry out simple civil engineering operations, by digging deep pits, burying the fastening piles deeply, and then stepping on them. The fastening effect and stability are acceptable in the short term, but the cables connected to the fastening piles are constantly pulled by the fastening piles due to changes in cold and heat and external forces, which will gradually cause holes or pores around the fastening piles. At the same time, due to the unavoidable problems of soil erosion and surface and underground soil quality changes that often occur in outdoor civil engineering operations, the soil's own water absorption and permeable characteristics will be softened after repeated rainwater, surface water or groundwater invasion and softening. The loss of movement and circulation will cause the above-mentioned holes to expand and deepen to form cavities, and eventually cause the fastening pile to lose its adhesion ability and eventually fall off. The grid inspection and maintenance personnel can only inspect and reinstall regularly, which cannot effectively prevent the above process
