Description
Technical field
The present invention relates to underground city pipe gallery technical field of construction, more particularly to a kind of positioning of city integrated piping lane
Line-putting method, it is adaptable to the line setting work of all kinds of piping lanes such as cast-type, precast splice type.
Background technology
It is also a most important step that the line setting work of pipe gallery is the first step of piping lane construction, positions the standard of work
The integral construction quality of true relation piping lane.In existing piping lane engineering construction, the line setting work before piping lane is excavated generally makes
Completed with GPS location instrument or total powerstation.During using GPS location instrument, by piping lane plane graph, the coordinate of skiagraph and elevation pair
Should be input in GPS Base Station, excavate prelocalization excavation line, all-the-way tracking digging process, at any time using GPS location cutting depth and
Position is excavated, instructs digging machine to construct, excavation completes to make piping lane main center line using GPS, into normal construction；Using whole station
When instrument is positioned, first by datum mark total powerstation pilot measurement to piping lane construction area, then orient every 50m along piping lane trend and face
When datum mark, piping lane excavation line is made using temporary fiducial point, in digging process using total powerstation positioning benchmark point height
Control cutting depth, foundation ditch is introduced after the completion of excavation by datum mark, orients piping lane main center line, completes to position work.
There is certain enforcement difficulty in both the above method.First, excavated using GPS location instrument and total powerstation,
The workload of positioning is larger, and in terms of kilometer, when multiple spot is excavated, GPS cannot take into account city integrated piping lane length with total powerstation, and GPS
It is higher with the price of total powerstation, it is impossible to a large amount of buyings；Second, GPS are higher using threshold with total powerstation, and those skilled in the art cannot
Its using method is grasped, needs to be equipped with the professional survey crew being consistent with project progress so that project management cost increases；The
Three, typically in -7m to -10m, this depth causes total powerstation to need multiple pilot measurement, cumulative errors in use to piping lane depth
Can accumulate because pilot measurement number of times is excessive, and cannot accurate repetition measurement.Therefore, it is badly in need of proposing that one kind is applied suitable for city integrated piping lane
The localization method of work, to improve the precision of measurement work, reduces technical staff's amount of labour, reduces cost, carries high-quality
Purpose.
The content of the invention
The purpose of the present invention is aiming at the problem of prior art presence, there is provided a kind of line setting of city integrated piping lane
Method, by with reference to GPS location instrument, level gauge measuring instrument, solving the difficulty of the line setting in piping lane construction, reduces construction
In demand to survey crew quantity, reduce survey crew workload, improve positioning precision, efficiently, quickly finish piping lane and apply
The positioning work of work, it is ensured that the requirement of duration and quality.
The object of the present invention is achieved like this：A kind of line setting method of city integrated piping lane, including GPS location instrument
Piping lane plane graph coordinate system control net is set up, earth excavation centrage is oriented, level control point is laid, positioning piping lane foundation trench adds
Deeply, change location is widened, piping lane foundation trench is excavated, level gauge elevation control depth, and first time absolute altitude is surveyed and set to foundation trench side during -5m
Slope, absolute altitude is surveyed and set when being excavated to foundation trench bottom -30cm, and piping lane bed course centrage is surveyed and set and Pipe rack centrage positioning, its feature
It is to carry out according to the following steps：
1), according to the benchmark control point of two and more than two for paying, GPS location instrument sets up piping lane plane graph coordinate system
Control net
Firstly the need of the engineering construction control point of two and more than two provided according to Construction Party or relevant departments, set up
The control net of GPS location instrument, as the benchmark of GPS location；
2), a cubic metre of earth central excavation line is gone out according to piping lane plane graph coordinate setting
According to the coordinate of piping lane site plan, piping lane foundation trench figure side central excavation line is oriented, by position of center line,
Excavating sideline is spread out using ribbon instrument；
3), move towards to lay level control point along piping lane
Because underground pipe gallery absolute altitude is risen and fallen with the fluctuating of top road, thus must according to piping lane skiagraph,
Along piping lane trend, high control point is marked with excavation line exterior measuring, absolute altitude control dot spacing arranges one less than 30m, at control point
While elevation is indicated, as the foundation of absolute altitude control when excavating；As piping lane by-pass road yet to be built builds, also can be by pavement of road absolute altitude
Foundation is controlled as absolute altitude；
4), position piping lane foundation trench to deepen, widen change location
According to each air outlet, line outlet, crossing coordinate in piping lane site plan, clearly survey and set out piping lane foundation trench node
Plus width position, white line is spread out, as excavation foundation；
5), piping lane foundation trench is excavated, level gauge elevation control depth
After preparation is finished, start foundation trench excavation work, foundation trench deep exploitation level gauge coordinates Sopwith staff, lining rope to be controlled
System, the foundation ditch gradient should be calculated substantially when excavating, it is to avoid be backbreak；
6), the survey of first time absolute altitude is set to foundation trench side slope during -5m
Because level gauge Sopwith staff length is usually no more than 7m, therefore level gauge is applied when 5m or so is excavated to by absolute altitude control
Point is projected on excavation slope, used as the absolute altitude control point for continuing to excavate downwards；
7) absolute altitude is surveyed and set when, being excavated to foundation trench bottom -30cm
Mechanical equivalent of light excavation should can pass through ribbon, Sopwith staff to substrate by the reserved 30cm surface dust labor cleanings of specification, absolute altitude
Determine；
8), artificial clear groove, basement process, piping lane bed course centrage is surveyed and set
Surface dust in labor cleaning's substrate above 30cm, basement process is carried out after check of foundation subsoil by design requirement, and GPS is used after examination
Positioning piping lane bed course centrage and node add width position；
9), cushion construction, levelling, waterproof construction, Pipe rack centrage positioning
Bed course template is installed according to bed course centrage, blinding concrete construction is carried out；Waterproof layer is carried out according to drawing requirement to apply
Work, using GPS location Pipe rack centrage after having constructed, hands over main structure construction.
Compared with prior art, it is an advantage of the invention that：Positioning precision is improved, efficiently, piping lane construction is quickly finished
Positioning work, it is ensured that duration and quality.
