The ordinary surveying line-putting method
Technical field
The present invention relates to a kind of method of measuring lead-in wire, particularly the lead-in wire method of concentric reducing circular section building.
Background technology
At present, in industry and covil construction were constructed, measuring unwrapping wire was a very important job.Traditional measurement paying-off implement is transit and total powerstation.But traditional survey instrument is while drawing this elevation of building line on surface level, very inconvenient in the situation that only have line of elevation of building.And there is no an effective measurement unwrapping wire way of cover.Especially the section when buildings is concentric reducing bowlder, uses traditional survey instrument to be difficult to the lead-in wire work of facade to plane.For example, the blast furnace engineering of metallurgical industry construction work.After the beginning civil engineering was complete, survey crew can stay and put the tapping hole center line at the cast house platform.But after blast furnace shell and frame installation have been constructed, often can be because a variety of causes causes on the cast house platform iron mouth center line damaged or wipe.But fitter's work is very important and iron mouth center line is to cast house.At this moment, just be difficult to this measurement setting-out work by the traditional measurement instrument.
Summary of the invention
The object of the present invention is to provide a kind of work of measuring that greatly reduced, reduced the ordinary surveying line-putting method of the difficulty of measuring.
Ordinary surveying line-putting method of the present invention, it comprises the following steps:
(a) each encloses 0 ° of point left while making installation to connect vertical equipment, and 0 ° of point on each circle is connected and draws 0 ° of line of facade;
(b) determine the horizontal projection position of described 0 ° of line by visual inspection;
(c) work light of adjusting down-lead device makes any the first point on 0 ° of line of optical registration facade that work light launches, simultaneously the irradiation launched of the regulation light source of down-lead device is on the vertical equipment housing, thereby obtains laying respectively at the second point of any first both sides and thirdly; Work light is positioned on the perpendicular bisector of two regulation light source line line segments and the plane at the light place that work light is sent and the parallel light that two regulation light sources send;
(d) measure the first arc length between first and second point and first and thirdly between the second arc length, if differing in size of the first arc length and the second arc length, in the situation that first of maintenance is constant, mobile down-lead device, until the difference of the numerical values recited of the first arc length and the second arc length is at 0.5mm-1.2mm, the position at mark down-lead device place then;
(e) with the down-lead device position of stentplacement at mark, and will fix after the plane leveling of laying down-lead device;
(f) down-lead device is placed on support and with down-lead device and transfers to level by mounting seat;
(g) mobile down-lead device makes be positioned on 0 ° of line of last furnace shell at first, and then the difference of the size of the first arc length and the second arc length be fixed on down-lead device on support at 0.5mm-1.2mm, again regulates down-lead device and makes it to be horizontal;
(h) regulate down-lead device the light corresponding point that work light is sent just in time are positioned on 0 ° of line of last furnace shell facade, then repeatedly adjust down-lead device position in the horizontal direction until the numerical values recited of the first arc length and the second arc length is equal;
(i) unclamp the work light set bolt of down-lead device, make the ground direction rotation of work light to erecting equipment, choose some points on the ground of installed vertical equipment, after then will these some points connecting, snap the line obtains 0 ° of line of facade and draws horizontal line on horizontal installation ground.
The invention has the beneficial effects as follows: by very simple method, in the ungratified situation of condition, the datum line of facade is guided on plane.Greatly reduce the work of measuring, reduced the difficulty of measuring.This method is applicable to the various situations that the facade datum line caused plane.The various buildings that applicable same upper radius-of-curvature equates and the surface of structures.Pillar for example, metope, variable cross section cylindrical shell, uniform cross section cylindrical shell, taper structures etc.Cross section is oval-shaped building and structures surface, because of radius-of-curvature unequal, and inapplicable.Because of manufacture craft less demanding, so be not suitable for accuracy requirement error 1mm with interior measurement lead-in wire work.As it is very high to measure lead-in wire operating error requirement, need improve equipment making technique.
