Description
Technical field
The present invention relates to a kind of construction methods, and in particular to a kind of construction method convenient for transmission of electricity stake disassembly.
Background technique
With the fast development of urban economy and the quickening of urbanization process, power engineering construction project is increasing.No
It needs not take up an area space of planes in road surface erection shaft tower and conducting wire, is easy to keep the power cable engineering of appearance of the city neat appearance also to get over
Come more.
The construction of normal cable engineering is all that fluting is laid with power pipe, causes to enable the disgustful road " zipper of citizen
Phenomenon ".Simultaneously during building power channel, for example all kinds of municipal administrations of node that can not be passed through by traditional excavation technology are encountered unavoidably
Cross pipe-line point, highway, railway, bridge, river and above ground structure etc..Therefore, conventional heavy excavation construction technology is increasingly
It is not suitable with the needs of urban development.
An emerging technology --- trenchless technology has obtained more and more extensive answer in power pipe engineering in recent years
With.Although trenchless technology is started late, but popularizing with application, and no matter theoretically trenchless technology, or is constructing
Process aspect has the development advanced by leaps and bounds.Although trenchless technology is come out first with high-tech advantage, no-dig technique
There is also many risks directly or indirectly in construction for technology.Since construction has scene property, complexity, mutability under earth's surface
And comprehensive feature, easily cause in construction surface buildings depression, roadbed subsidence cracking, underground structure and underground to have pipeline
Damage etc. the problems such as.
Since the method that Horizontal Directional Drilling is excavated relative to tradition has many advantages, so that it is being laid with city electricity
Hydraulic piping using more and more extensive.
Power pipe construction is combined back there are multitube and is dragged with construction characteristics such as compaction groutings, resistance when not only back to drag
Increase, and the grouting pressure that acts on pipeline outer wall while pipeline critical external compressive resistance ability can be reduced, with time dragging for single pipe
Construction has significant difference.
To guarantee the safety of pipeline itself and the quality of engineering, the pull-back force in construction should be carried out before going back to hauling pipe road
It calculates, and force analysis is carried out to electricity channel, to guarantee the safety in pipeline returning and mortar depositing construction.
Summary of the invention
The technical problem to be solved by the present invention is to the disassembly installation steps of current power transmission stake are cumbersome, the construction in entire stake face
Process is slowly, and it is an object of the present invention to provide a kind of construction method convenient for transmission of electricity stake disassembly, solves the problem above-mentioned.
The present invention is achieved through the following technical solutions：
A kind of construction method convenient for transmission of electricity stake disassembly, described method includes following steps：S1：It is flat that place is carried out first
It is whole, will first be evened out by Center stake formation level whole within the scope of foundation construction, remove subsurface, the barrier on ground, repair lead into
The sidewalk of stake position；S2：Water supply pipe and power supply line are installed, carries out a point hole by design drawing requirement and measures, not by pile foundation
The place setting pile foundation axis of construction infection and high process control stake, and perform record；S3：Shaft tower number in pool uses
Sand pocket cofferdam, and the water in cofferdam is drained, filling pile construction should be segmented according to the length of reinforcing cage of design, and reinforcing bar is arranged
Cage machining shed and cement store canopy, backup power source should also be arranged, sandstone stacks field and cinder field out；S4：It is impacted using mud off
The clay storage field of 2 times of single pile sides amount should be arranged in drilling machine pore-creating filling pile, using mud off rotary rig pore-creating filling pile,
The mud pit of one 3 times of single pile sides amount and the mud-settling pit of 2 times of single pile side amount should be set.
Casing is made of 4~8mm steel plate, should be greater than bit diameter 100mm with its diameter when rotary rig；Use impact drill
When machine, preferably greater than bit diameter 200mm.
Casing position should be buried correctly, tamp between casing and crater wall using clay, casing center and stake position centre deviation
It is not greater than 50mm.
Shield-tube embedment depth is not preferably less than 1m in clay, and 1.5m, and mud face in retaining hole are not preferably less than in sand
It is higher by level of ground water 1m or more.
Compared with prior art, the present invention having the following advantages and benefits：By trenchless technology and power cable
Laying combine, for guarantee pipeline itself safety and engineering quality, return hauling pipe road before reply construction in return drag
Power is calculated, and carries out force analysis to electricity channel, to guarantee the safety in pipeline returning and mortar depositing construction.To current
Power transmission and transformation comb trenchless engineering construction method has carried out effective supplement, has also standardized supervisor in non-excavation laying electric power
Supervisory basis and supervision behavior in pipeline construction.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below with reference to embodiment, the present invention is made
Further to be described in detail, exemplary embodiment of the invention and its explanation for explaining only the invention, are not intended as to this
The restriction of invention.
