Construction method for erecting telegraph pole on mountain land

Abstract

The invention discloses a construction method for erecting a telegraph pole on mountain land. The construction method comprises the following specific steps: an inverted-trapezoidal deep pit with thevertical front end and the inclined rear end is excavated in the position where the telegraph pole is to be erected; the root of the telegraph pole is pushed into the deep pit along the slope of the deep pit from back to front till the root of the telegraph pole reaches the bottom end of the deep pit; an inclined pull line connected to the top end of the telegraph pole is pulled in front of the deep pit to vertically pull the telegraph pole up, and the bottom end of the inclined pull line is fixed to the ground surface through a ground anchor; the deep pit is buried through soil excavated during deep pit excavation, and compacted; shallow pits are excavated around the telegraph pole and compacted again; and concrete foundations are poured in the excavated shallow pits, and natural curing is conducted for ten days or above. According to the construction method, the telegraph pole can be prevented from toppling, a safety guarantee is provided for an operator, and the firmness of the telegraph pole after soil filling compaction can be improved, so that the firmness meets the telegraph pole erection requirements.

Description

technical field [0001] The invention relates to a construction method for erecting electric poles, in particular to a construction method for erecting electric poles in mountainous areas. Background technique [0002] When the electric power department erects electric poles, it usually excavates thick pits such as electric poles vertically at the place where the electric poles are pre-erected. Fill the soil and compact it. Due to the complex and diverse erection locations of electric poles, especially when erecting electric poles in mountainous areas, the electric poles can only be manually placed into vertical deep pits because the crane cannot go up the mountain. During the movement of the pit, the workers could not support the utility poles, and the utility poles swayed greatly and could easily fall over and injure the operators; and the mountainous soil was loose, and the utility poles were still not firm after filling and compacted, which did not meet the requirements ...

Problems solved by technology

Due to the complex and diverse erection locations of electric poles, especially when erecting electric poles in mountainous areas, the electric poles can only be manually placed into vertical deep pits because the crane cannot go up the mountain. During the movement of the pit, the operators could not support the utility poles, and the utility poles swayed greatly and could easily fall over and injure the workers; and the mountainous soil was loose, and the utility poles were still not firm after filling and tamping, which did not meet the requirements for utility pole erection
