Abstract
The invention provides a forcing centering plate, comprising a centering plate (1). A central hole of the centering plate (1) is provided with a connecting bolt (2); the centering plate (1) is also provided with a bench mark (3); the bottom of the central hole of the centering plate (1) is provided with a connecting pipe (6) and a PVC pipe (4) which is connected with the connecting pipe (6); and the bottom surface of the centering plate (1) is also provided with at least two fixed reinforcing steel bars (5). The forcing centering plate has the advantages that a key part is made of a stainless steel material which is not easy to rust, can ensure the centering precision and has long service life; the top adopts an opening structure, thus eliminating the hidden trouble of damaging, rusting and the like; a rainwater guide hole ensures the centering hole not to be blocked; the embedding depth of the underground part of a centering observation pier is more than 1.5 times of the ground height, thus effectively preventing the inclination of the observation pier and reinforcing the stability of the observation pier.
Description
Technical field
The present invention relates to field of measuring technique, a kind of specifically forced centering plate and method for embedding.
Background technology
In the high precision engineering survey, the error of centralization that requires instrument and observe board is less than 0.2mm, and conventional optics cultellation method and plumb bob can't arrive this requirement to point methods.Particularly some need carry out the measurement engineering project (installing and measuring etc. as deformation observation, precision equipment) of repeated measures repeatedly, guarantees that accuracy of alignment is better than 0.2mm and is even more important.
Summary of the invention
The objective of the invention is to develop a kind of total powerstation and accuracy of alignment of observing board of making and reach forced centering plate and the method for embedding that 0.2mm requires.
A kind of forced centering plate of the present invention, comprise: thoughts of returning home plate 1, the center pit of thoughts of returning home plate 1 is equipped with coupling bolt 2, leveling point 3 also is housed on the thoughts of returning home plate 1, the pvc pipe 4 (rainwater pod apertures) that connecting pipe 6 links to each other with connecting pipe 6 is equipped with in the center pit bottom of thoughts of returning home plate 1, and at least two fixedly reinforcing bars 5 also are equipped with in the bottom surface of thoughts of returning home plate 1.
The center-hole diameter mismachining tolerance of thoughts of returning home plate 1 should be greater than+0.1mm, and coupling bolt 2 links to each other the diameter mismachining tolerance of part with center pit should be greater than-0.1mm.
Thoughts of returning home plate 1, coupling bolt 2 and leveling point 3 should adopt stainless steel material.
The method for embedding of a kind of forced centering plate of the present invention, its step is as follows:
1. excavating the length of side is that 1～1.5m, the degree of depth are the square hole of 1.3～1.5m;
2. at the center in hole with the rig steel pipe 9 that to squeeze into a diameter be 400～600mm, its degree of depth is 3～5m overhead;
3. under surface level 1～1.2m, prick the foursquare reinforcing bar chassis circle 8 of a 1～1.2m;
4. prick the square column type steel ring 7 that height is 1.8～2.2m on chassis steel ring 8, its length of side is 250mm;
5. the fixedly reinforcing bar 5 with forced centering plate is welded in steel pipe 9 tops, must make the upper surface of the thoughts of returning home plate 1 of forced centering plate keep horizontality, loads onto template outside steel ring 7,8;
6. deposit concrete makes the surface of forced centering plate concordant with the surface level of thoughts of returning home observation pier 10, after concrete curing is good, removes mould;
7. backfill sand in the hole, compacting, on the sand face and the concrete thoughts of returning home that is exposed at surface level top observe the outside surface embedding marble slab of pier 10.
When observing repeatedly when measuring, as long as scope is installed on the screw thread, of coupling bolt 2 light is inserted in the center pit of thoughts of returning home plate 1 and can measure, so no matter when measure, always benchmark (accuracy of alignment is within 0.1mm) accurately.
The advantage of a kind of forced centering plate of the present invention and method for embedding is: critical component adopts stainless steel material, is difficult for corrosion, can guarantee accuracy of alignment, long service life; Open architecture is adopted at the top, has eliminated destroyed and hidden danger such as corrosion; The rainwater pod apertures guarantees that thoughts of returning home hole is not blocked; The thoughts of returning home observation pier under ground portion depth of burying should can effectively prevent to observe pier itself to tilt greater than 1.5 times of ground height, has strengthened the stability of self.
