Description
Technical field
The present invention relates to field of civil engineering, be specially fixed point line-putting method in hole in a kind of hole.
Background technology
In civil engineering foundation pit construction, often run into the excavation comprising several foundation pits in a larger foundation ditch.After the generous amount earth excavation of foundation ditch completes, leave bottom 300mm dark, then the steel plate of welded bands sword on the tooth of digging machine, coordinates the little foundation pit be manually used in excavation pit, strikes off foundation ditch simultaneously.Some foundation pit is than comparatively dense, and workmen needs each angle point determining foundation pit with instrument, sprinkles lime line, but digging process scraping back and forth, and lime line does not see Chu soon.
Summary of the invention
The object of the invention is to, provide in a kind of simple, quick, stable hole and cheat line-putting method.
In order to achieve the above object, the present invention is achieved in that
In a kind of hole, hole fixed point line-putting method, is characterized in that: comprise the steps:
Step 1: in the large foundation ditch dug, at respective angle point and correct position place according to blueprint, by introducing stake position, several reference mark with the method for surveying setting-out, the reference point established is surveyed as follow-up little foundation ditch in this several reference mark;
Step 2, in Electronic Design figure, finds out angle point and nearest two reference mark of the little foundation ditch of required excavation, and marks out the distance at this angle point and these two reference mark;
Step 3, has marked distance by each angle point of this little foundation ditch and other little foundation ditches by step 2, and has been printed by drawing;
Step 4, at the scene in foundation ditch, release the lining rope of angle point length at nearest two reference mark to its place of one section of some little foundation ditch obtained by above step, lining rope one end is fixed on this stake position, reference mark, the other end draws one section of camber line on the ground of the general orientation of little foundation ditch angle point, just can obtain an intersection point of two arcs; Also the length that the free end of two cotton ropes is corresponding can be found respectively, then free end coincide point is pinched at finger tip, roughly direction simultaneously toward this little foundation ditch angle point is moved, until the position that two cotton ropes are all tightened, is the point that will look for immediately below finger correspondence position;
Step 5, with reference to step 4, finds out other several angle point in same foundation hole;
Step 6, just can find four angle points of all foundation pits by above method.
Fixed point line-putting method in hole in described hole, step 3 can also be: the carrier being loaded with Electronic Design figure is transported to operation field, needs which point can directly measure on Electronic Design figure to the distance of certain two point of fixity.
In described hole, hole fixed point line-putting method, lining rope has the sign point that spacing distance is 1 meter.
Fixed point line-putting method in hole in described hole, the reference mark of in earlier stage excavating large foundation ditch and introducing can be selected in selected reference mark.
Fixed point line-putting method in hole in described hole, the height of stake position, set reference mark in one plane.
This method adopts above-mentioned steps, and it has following advantage:
1, the method is easy to learn, and operating personnel grasps comparatively fast, easy to operate, comparatively fast can enter shoveling and bed course staged construction;
2, without the need to always checking complete foundation ditch corner points with instrument, surveying work amount is decreased;
3, decrease the spreading amount of lime line in classic method, decrease and repeat erection instrument, draw the surveying work amounts such as chi;
4, the method only needs two builders according to figure paper size, little foundation ditch angle point can be surveyed and set out, decrease the requirement to special instrument and operating personnel with lining rope.
Accompanying drawing explanation
Fig. 1 is operation schematic diagram of the present invention.
Embodiment
The present invention is further illustrated below by way of specific embodiment.
As described in Figure 1, in a kind of hole, hole fixed point line-putting method, is characterized in that: comprise the steps:
Step 1: in the large foundation ditch dug, at its angle point and center position according to blueprint, by introducing the stake position at reference mark 1, reference mark 2, reference mark 3, reference mark 4, reference mark 5 with the method for surveying setting-out, the reference point established is surveyed as follow-up little foundation ditch in these five reference mark;
Step 2, in Electronic Design figure, finds out angle point and nearest two reference mark of the little foundation ditch of required excavation, and marks out the distance at this angle point and these two reference mark;
Step 3, has marked distance by each angle point of this little foundation ditch and other little foundation ditches by step 2, and has been printed by drawing;
Step 4, at the scene in foundation ditch, release the lining rope (in Fig. 1 L1, L2) of angle point length at nearest two reference mark to its place of one section of some little foundation ditch obtained by above step, lining rope one end is fixed on this stake position, reference mark, the other end draws one section of camber line on the ground of the general orientation of little foundation ditch angle point (in Fig. 1 A), just can obtain an intersection point of two arcs; (also can find the length that the free end of two cotton ropes is corresponding respectively, then free end coincide point is pinched at finger tip, roughly direction simultaneously toward this little foundation ditch angle point is moved, until the position that two cotton ropes are all tightened, is the point that will look for immediately below finger correspondence position);
Step 5, with reference to step 4, finds out other several angle point (in Fig. 1 B, C, D) in same foundation hole;
Step 6, just can find four angle points of all foundation pits by above method.
Fixed point line-putting method in hole in described hole, step 3 can also be: the carrier being loaded with Electronic Design figure is transported to operation field, needs which point can directly measure on Electronic Design figure to the distance of certain two point of fixity.
In described hole, hole fixed point line-putting method, lining rope has the sign point that spacing distance is 1 meter.
Fixed point line-putting method in hole in described hole, the reference mark of in earlier stage excavating large foundation ditch and introducing can be selected in selected reference mark.
Fixed point line-putting method in hole in described hole, the height of stake position, set reference mark in one plane.
This method adopts above-mentioned steps, and it has following advantage:
1, the method is easy to learn, and operating personnel grasps comparatively fast, easy to operate, comparatively fast can enter shoveling and bed course staged construction;
2, without the need to always checking complete foundation ditch corner points with instrument, surveying work amount is decreased;
3, decrease the spreading amount of lime line in classic method, decrease and repeat erection instrument, draw the surveying work amounts such as chi;
4, the method only needs two builders according to figure paper size, little foundation ditch angle point can be surveyed and set out, decrease the requirement to special instrument and operating personnel with lining rope.
