13, adjust the position of middle layer and top layer circular support pedestal 1.
In use, operating as follows:
1. preparing M20 bolt (pre-embedded bolt 6), Φ 48mm steel pipe (vertical upright bar 8) and bottom steel plate (fixation steel plate 9) to weld
It connects securely, pre-embedded bolt 6 is welded in the 9 face hole Shang Ge of fixation steel plate；
2. surveying setting-out determines that bottom plate is normally carried out and pours, the pre-buried M20 pre-embedded bolt 6 of bottom center；
3. after the completion of bottom slab concreting, according to inspection shaft center, the interior outside of inspection shaft abutment wall being drawn with the line of ink marker, is then installed
Vertical upright bar 8, the fixation steel plate 9 that vertical upright bar 8 is welded by the bottom M20 pre-embedded bolt 6 pre-buried with bottom plate are connect, it is ensured that perpendicular
To the stabilization and verticality of upright bar 8；
4. flower basket bolt 10 to be retracted to most short, installation inner circle tube template 2, while arc-shaped support bar 12 being installed, and lead to
Bolt is crossed to be connected firmly with T-type link block 11；According to the graduated scale rotation on flower basket bolt 10, the length of flower basket bolt 10 is adjusted
Degree, it is ensured that the length that four flower basket bolts 10 adjust is unified, and inner circle tube template 2 is pushed into line of ink marker edge, meets the knot of Jing Qiang
Structure position；
5. outer circle tube template 3 is installed, at the same installing bottom layer to pull rod 4 is drawn, carried out using reinforcing bar on the inside of outer circle tube template 3
Inner support meets wall body structure thickness；After outside adds stirrup 5, reinforcing stirrup 5 is blocked using butterfly and is connected into arc-shaped support bar 12
It is integrated, bottom is fixed to be completed；
6. installing circular support pedestal 1 at the middle part of vertical upright bar 8 and top；Sleeve 13 is passed through into vertical upright bar 8, is fallen
To 1.5m range, rotational fastener bolt 14, fixes sleeve 13 does not allow it to be slided, then will be vertical using same method
The fixation steel plate 9 at 8 top of upright bar is welded and fixed with sleeve 13, and installs arc-shaped support bar 12, four gaily decorated basket spiral shells of synchronous adjustment
Bolt 10 allows its scale to show length as four flower basket bolts 10 of bottom；
7. then temperature pier inner circle tube template 2 is penetrated to pull rod 4 is drawn, outside is installed stirrup 5, is adopted between two templates
With reinforcing bar inner support, the bolt of 12 inside of butterfly card and arc-shaped support bar is then fastened simultaneously, interior outboard template is tensed；
8. pouring inspection shaft concrete between interior cylinder template 2 and outer circle tube template 3；
9. after the completion of pouring, by 1.~7. inverted sequence form removal when being suitable for demoulding, after dismounting in time to the positions such as bolt into
Row cleaning prepares to use next time.
The present invention is before use, first have to ensure that bottom slab concreting is completed in inspection shaft, and ensure the pre-buried pre-embedded bolt 6 of bottom plate
The accuracy of position.This secondary design meets the concrete inspection well within the scope of diameter 1.9m to 2.1m, remaining size can basis
Concrete condition adjusts the length of gaily decorated basket screw rod and arc-shaped support bar 12, but structure and principle are constant.
