Assembly of Bottom panel block

Bottom Panel Block Assembly
Sequence and Procedure
1) Attached the sealing tape to the fl**ge for all of the bottom panel.

2) Method to Apply Tapes
a) The sealing tape should be applied to all assembled fl**ge surfaces.
b) The centre side of the sealing tape should be overlapped by about 50mm (as shown in the below photo )

3) To assemble a bottom panel block, fIrst connect several bottom panels into a sub-block. Determine the block size according to the site condition, the work space, number of workers, use or non-use of a crane, etc.
A block that is too large cause difficulty in relocation and other work. Therefore, it is recommended that one block be limited to 10 panels x 2rows.

4) Arrangement and type of bottom panels.
Place bottom panels one by one upside (as shown in Fig. 2).
When installing a drain nozzle, place a pit panel in the pre-determined position.

5) Assembly of Drain Panel
Using a hole saw(for a small bore),and a jigsaw(for large bore), the required holes may be cut into panels.

6) Assembly of sub-blocks is done by connecting panels in one direction only.

7) All bolts/nuts for connecting bottom panels shall be M10 X 50 ℓ. As for 8 Bolts/nuts are used fo a 1m length side and 4 are used for 0.5m length side of a panel.

8) Perforate a hole using a fixture

9) For bolt / nut tightening sequence : First tighten the 3th bolt/nut from each end of the fl**ge. Then tighten 4th, 5th,6th, and 1st,8th. Lastly the 2nd, 7th bolts/nuts.

10) Adjusting by levering the tapered bars horozontally and vertically.

11) Assemble one more sub-block using the same procedure as above.

12) Connect together two assembled sub-blocks into one complete 10-panel bottom block.

Panel Quantity Formula
For example
6mW * 7mL * 2mH
84 Ton (22193 Gallon) => 136㎡

Wall panel D grade (1m * 2m) : 26 unit
Roof panel E grade (1m * 1m) : 41 unit
Manhole Φ780 (1m * 1m) : 1 unit
Bottom panel D grade (1m * 1m) : 41 unit
Drainage panel C grade (1m * 1m) : 1 unit

So we can make the Formula
X mW * Y mL * Z mH
If Z height is 1m, 1,5m, 2m,
Wall panel (1m * Z m) : 2(X + Y) unit
Roof panel (1m * 1 m) : (X x Y) - 1 unit
Manhole (1m * 1m) : 1 unit
Bottom panel (1m * 1m) : (X x Y) - 1 unit
Drainage panel (1m * 1m) : 1 unit
