Abstract
The utility model discloses a steel tower rising structure of a power transmission line, wherein the steel tower rising structure comprises a graft tower body of a rectangular truss structure and an original steel tower cement foundation; the periphery side of the graft tower body is provided with a reinforcing diagonal bracing; and the original steel tower cement foundation is provided with a reinforcing anchor bolt. Through the structure, a great amount of sand stones, cement and reinforcing steel bar materials can be saved, the modified construction cycle and the power outage time are shortened greatly, at the same time, and the problem that the foundation can not be poured additionally to erect a new steel tower by adopting a traditional method because of the geographic environment restriction of the channel and the power outage time restriction is solved.
Description
Technical field
The utility model belongs to high-voltage transmission line towers renovation technique field, particularly a kind of iron tower of power transmission line rising structure.
Background technology
Along with the development of traffic infrastructure, railway, speedway constantly increase, and safe distance is not enough over the ground to bring the transmission line of electricity of crossing over railway, speedway thus, and transformation must in time raise.At present; Carry out the method that transmission line of electricity raises and transforms, normally original iron tower of power transmission line is torn open and moved, then with the broken removal of concrete pedestal; Again enlarge the cast basis; By section at the bottom of the new size design making iron tower, after former tower body is connected, new tower body is installed on the new basis simultaneously through four pre-embedded anchoring bolts.This method not only will be wasted a large amount of sandstone, cement and reinforcing bar material, and the effort of taking a lot of work, and construction period is very long, influences power transmission efficiency.Limited by restriction of passage geographical environment and power off time, can't adopt the conventional method situation of the new upright iron tower in cast basis in addition, more make electric power enterprise be in the dilemma.
The utility model content
The purpose of the utility model is to provide a kind of and can saves material to greatest extent, improves rebuilding construction efficient, shortens the iron tower of power transmission line rising structure of construction period and power off time.
The technical scheme that purpose adopted that realizes the utility model is: a kind of iron tower of power transmission line rising structure; The grafting tower body and the former iron tower concrete pedestal that comprise the rectangle trussed construction; All sides of said grafting tower body are provided with the reinforcement diagonal brace, and former iron tower concrete pedestal is provided with foot bolt intentinonally.
The iron tower of power transmission line rising structure of the utility model; Can practice thrift a large amount of sandstone, cement and reinforcing bar material; Shorten rebuilding construction cycle and power off time greatly; Solve restriction of passage geographical environment and power off time restriction simultaneously, can't adopt the conventional method problem of the new upright iron tower in cast basis in addition.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Referring to Fig. 1; The iron tower of power transmission line rising structure of the utility model; Be the grafting tower body 2 and former iron tower concrete pedestal 1 of rectangle trussed construction, the two ends up and down of said grafting tower body 2 respectively can with section 4 at the bottom of the former tower body and former 5 corresponding connections of stone bolt, all heel posts of grafting tower body 2 are provided with reinforcement diagonal brace 3; With the flexural strength of enhancing grafting tower body 2, and on former iron tower concrete pedestal 1, set up and put four foot bolts 6 intentinonally.Like this; Can make improved tower body have enough compressive strength, flexural strength and wind resistance stability; Simultaneously when carrying out iron tower rising transformation; Only need on former iron tower concrete pedestal 1, set up to put four foot bolts 6 intentinonally, after section 4 integrated removals at the bottom of former tower body and the former tower body are raise, again with the two ends up and down of grafting tower body 2 distinguish can with section 4 at the bottom of the former tower body and former 5 corresponding connections of stone bolt; The lower end of strengthening diagonal brace 3 respectively with four intentinonally foot bolt 6 be connected, promptly accomplish the rising transformation of whole iron tower.Can practice thrift a large amount of sandstone, cement and reinforcing bar material thus, shorten rebuilding construction cycle and power off time greatly, solve restriction of passage geographical environment and power off time restriction simultaneously, can't adopt the conventional method problem of the new upright iron tower in cast basis in addition.
