Description
Technical field
The present invention relates to the realm of building construction, more particularly to a kind of high-tension cable power channel original position suspension protection side
Method.
Background technique
City high-tension cable is more using the form of underground of being protected in is laid with, and ensure that safety and residential electricity consumption
Stability, but whole laying higher cost.When need among city carry out heavy duty work construction, as megastore or
When building of iron, buried cable need to carry out certain protection and evade.
There are two types of common paving modes for existing underground high voltage cable tool.The first paving mode is to be spaced a spacing
From an electricity well is just arranged, which is formed by concrete casting, and high-tension cable is formed and determined by passing through in electricity well
, well lid used for overhaul is reserved at the top of electricity well.Second of paving mode be spaced a distance by pipe pillow will be high
Voltage cable carries out gathering fixation, then pipe pillow is closed by the power channel sealed, and constitute the positioning branch of high-tension cable
Support.
In existing construction method, need to dismantle electricity well or power channel comprehensively, and to generated building
Waste material carries out cleaning carrying.After completing forcible entry comprehensively, hanged after high-tension cable progress suitable protecting, then through Bailey bracket
It hangs.After the completion of construction, electricity well or pipe pillow are reinstalled in situ, taken time and effort.
Summary of the invention
It is an object of the invention to overcome the deficiency of the prior art, provides a kind of high-tension cable power channel suspention in situ
Guard method greatly shortens the construction period of high tension power cable suspension protection, so that construction efficiency rises；It decreases and builds simultaneously
The generation for building waste material, saves construction cost.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of high-tension cable power channel original position suspension protection method, the power channel are embedded in underground, and along underground
The setting of high-tension cable distribution lines interval, and high-tension cable is crossed and mistake by the power channel；Multiple groups are equipped in the power channel
Pipe pillow, the cooperation attaching of each group of pipe pillow form rectangular array, and the high-tension cable in power channel sequentially passes through multi units tube pillow group
At rectangular array positioned；The following steps are included:
The native stone of above power channel and side is removed, keeps the exterior wall of power channel completely sudden and violent by preparation of construction step
Dew sets up the Bailey bracket for being across high-tension cable extending direction two sides in the top of power channel；
Exterior wall separating step uses rope if being drilled with longline saw hole respectively in the exterior wall top surface of power channel and side
Saw equipment separates the exterior wall top surface of power channel and side cutting along the rope saw hole being drilled with, successively will be outer using lifting equipment
The top surface of wall and side are carried far from scene；
The rectangular array that multi units tube is rested the head on is separately constituted rectangular array and reinforced by high-tension cable fixing step, and will be high
Package protection is carried out on the outside of voltage cable, and the pipe pillow of bottom is finally both secured to multiple load bearing support bars or bearing plate；
Step is hung, locked mechanism is set on the multiple bearing bars or bearing plate fixed with pipe pillow, it will using steel strand wires
Multiple bearing bars or bearing plate are hung by locked mechanism is fixed on the Bailey bracket.
As a preference, further include dregs cleanup step after the suspension step, the dregs that construction site is generated
Uniformly cleared up.
As a preference, the side and top of the high-tension cable fixed are equipped with buffer layer, which uses resistance to punching
Resistant to shearing material is hit to be made.
As a preference, the buffer layer includes the side buffer layer being made of sandbag pile and is made of the double-deck bamboo slab rubber
Upper buffer layer.
As a preference, further including reconstitution steps in situ, is completed in all constructions, need again to bury power channel
When underground, the exterior wall that cutting is removed is installed into go back to corresponding position in situ, and bonded by cement.
As a preference, diameter >=15.2mm of the steel strand wires, hitch point interval >=1.5m of adjacent steel strand wires.
As a preference, the locked mechanism is annular buckle, annular buckle is equipped with the clamping for being biased to wherein side
Slot, the bearing bar two sides are equipped with location hole, and the state that the annular is snapped in clamping groove towards dip direction is installed on this
Location hole.
The beneficial effects of the present invention are:
1, the construction period is greatly shortened.Realize the high tension power cable suspension that do not remove under pipe pillow state.When construction is completed
Afterwards, it is only necessary to pipe be rested the head on into inserting reduction, can continue to realize the function that high-tension cable is fixedly mounted.Such construction method greatly contracts
The construction period of short high tension power cable suspension protection, so that construction efficiency rises.The generation of construction waste is decreased simultaneously, is saved
Construction cost is saved.
2, keep work progress more safe and reliable, be hardly damaged high-tension cable.Pipe pillow itself has protection high-tension cable
Function, not to pipe pillow dismount, and directly to pipe pillow hang, can prevent dismount pipe pillow during to high-voltage electricity
Cable damages.
3, after the completion of constructing, cementing is installed and passed through to the wall body in situ under cutting, greatly accelerates construction speed,
And save construction material.
Invention is further described in detail with reference to the accompanying drawings and embodiments；But a kind of high-tension cable electricity of the invention
Power channel original position suspension protection method is not limited to the embodiment.
