Description
Technical Field
The invention relates to the field of communication overhead line engineering construction, in particular to a protection device for an overhead line.
Background
With the upgrading and transformation of the communication network in China, the construction of communication infrastructures in China is accelerated. However, in natural disaster frequent areas of China, particularly natural disaster frequent points such as earthquakes, debris flows, floods and the like, communication accidents continuously occur, such as electric pole breakage, inclined or washed down of a communication overhead line and the like, so that part or all of the communication cable is interrupted. These incidents not only result in loss of communication subscribers and communication property units, but also result in difficulties in reestablishing and maintaining the communication transport network after the disaster.
In order to reduce the occurrence of communication accidents and prevent such accidents, as shown in fig. 1, a construction scheme of a pier (stone or plain concrete) 002 is generally used at present for protecting an overhead line pole 001 at a disaster or disaster-frequent point to reinforce a pole base of an overhead line. The fender 002 is generally cylindrical in shape and the overhead line pole 001 is fixed in the middle of the fender 002.
The solution is relatively low in cost, simple in construction and capable of firmly fixing the pole base of the overhead pole to a certain extent, but is weak in impact force, limited in bearing and compression capacity, easy to swing, collapse and be washed out when a strong natural disaster (earthquake, debris flow, flood and the like) comes, and cannot prevent and effectively protect the safety of the communication overhead line to the maximum extent.
Patent application 201611045710.1 discloses a pier protecting structure and a construction method thereof. The pier protection structure comprises a pier body and a pier protection layer; the inner side wall of the bridge pier protective layer is provided with a connecting bolt; the bridge pier protection layer is fixedly arranged on the outer side wall of the bridge pier body through the connecting bolts; the connecting bolts are embedded into the bridge pier body. The protective sleeve of the bridge pier protective structure disclosed by the invention is wrapped on the outer side of the bridge pier, and the contact between water and the concrete bridge pier is thoroughly isolated by utilizing the high anti-seepage performance of the protective sleeve, so that corrosion to internal steel bars and concrete is inhibited, the bridge pier is effectively protected, and the service life is prolonged.
However, this patent application still employs a cylindrical pier having the drawbacks of weak impact, limited load bearing and compression capacity. Meanwhile, because the electric pole is fixed in the pier, when natural disasters occur, cables in the communication overhead line are constrained by the electric pole, and the electric pole is easily broken under the action of external impact force due to the lack of enough elastic telescopic space, so that the cable is broken, and the communication line faults are generated. The pier protection solution can protect the overhead line to a certain extent by reinforcing the pole base of the overhead pole, but is limited or influenced by factors such as regions, geographical environments, geological conditions, climate conditions and changes besides weak impact force and limited bearing and compression capacity, so that natural disasters or disaster frequent points can not be effectively implemented or applied, and the safety of cables in the communication overhead line can not be protected in a multi-scheme and effective manner.
