As depicted in figs. 1 and 2, present embodiment discloses a kind of forced centering for precise engineering survey observes stake
Manufacture method, is carried out in accordance with the following steps：
(1) manual type is adopted to excavate stake holes, until this stake holes is excavated to basement rock 1 at designed hole position；In stake holes
It should be noted that controlling vertical degree of the peg hole, checking loosened soil, exclusion stake holes internal water accumulation in hole quality, cleaning stake holes in mining process.
(2), after the completion of stake holes is excavated, steel reinforcement cage 2 is laid in the lifting into stake holes, and steel reinforcement cage 2 bottom should be positioned on basement rock 1,
And steel reinforcement cage 2 should reserve certain design height more than ground, this highly typically in the range of 1000-1500mm, with become
After stake, survey crew facilitates operation to be defined.In the present embodiment, reserved height more than ground for the steel reinforcement cage 2 is 1200mm.
(3) hang after steel reinforcement cage 2 puts in place, casting concrete in stake holes, thus form concrete-pile ground in below ground
Lower part 3；Concrete-pile under ground portion 3 is cross section is foursquare reinforced column, the length of side of this square cross section
For 800mm.
(4) after below ground concrete setting (i.e. after concrete-pile under ground portion 3 solidification forming), then by ground with
Upper reserved 1200mm steel reinforcement cage 2 formwork casting concrete, forms concrete-pile aerial partss 4.
Wherein concrete-pile aerial partss 4 include cross section is foursquare stake pile 6, the side of this square cross section
A length of 300mm.In addition to stake pile 6, concrete-pile aerial partss 4 also include being arranged at stake pile 6 bottom and being directly located
In the platform 5 on ground, platform 5 height is 300mm, and the length of side of its square cross section is 1200mm.Platform 5 and stake pile 6
The concrete-pile aerial partss 4 being constituted, its total height is 1200mm.
Because high process control is also a part for precise engineering survey work, in order to improve the use function of stake, permissible
Erect bench mark 7 in platform 5, to control the elevation of engineering.Bench mark 7 is normally at stake pile 6 at a distance of 10-
At the position of 20cm, insert concrete before the above concrete initial set in ground and reserve 1-2cm in platform more than 5.
(5) before the above concrete setting in ground (i.e. before concrete-pile aerial partss 4 solidification forming), in concrete
The center embedding forced centering bolt 8 of stake aerial partss 4 top (namely stake pile 6 top), this forced centering bolt 8
Diameter and measuring instrument base bottom bolt hole coupling, with smooth, measuring instrument is installed.
(6) after embedding forced centering bolt 8, on the top (namely top of stake pile 6) of concrete-pile aerial partss 4
Embedding forced centering disk 9, and so that forced centering bolt 8 is passed by the circle centre position of forced centering disk 9, forced centering disk 9
A diameter of 140mm.It should be noted that should be using circular bubble by forced centering disk 9 during embedding forced centering disk 9
Upper surface horizontalization.
(7) the above concrete setting in ground, i.e. concrete-pile aerial partss 4 solidification forming are waited.
(8) last, in order to protect the forced centering completing to observe stake, arrange around forced centering observation stake
Some concrete filled steel tube fender posts 10 red and white, to prevent it from being destroyed.A diameter of 200mm of fender post 10, totally
It is highly 1100mm, wherein aerial partss are 500mm, and under ground portion is 600mm.
Although being described to the preferred embodiments of the present invention above in conjunction with accompanying drawing, the invention is not limited in
The specific embodiment stated, above-mentioned specific embodiment is only schematically, is not restricted, this area common
Technical staff, under the enlightenment of the present invention, in the case of without departing from present inventive concept and scope of the claimed protection, also may be used
To make the concrete conversion of a lot of forms, these belong within protection scope of the present invention.
