Butterfly Valve Installation and Chamber Construction

How to install a Butterfly Valve and construct Chamber?

Here I share some pictures describing procedures of Butterfly Valve installation and Chamber construction for 1200 mm diameter DI pipe.

1. 100mm thick cc casting with C20 concrete. Then make a layout for re-bar binding.




2. Then start re-bar binding according to drawing. In this case 16mm dia Grade 60 re-bars are used. Must maintain the c/c distance and clear cover. During bending the re-bar development length must have to maintain as per drawing.



3. When re-bar binding finish then the workmanship must be checked by the consultant.






4. After checked by the consultant start form setting. Use required size of block to maintain clear cover. Provide necessary support to prevent form failure during casting. In this case 75mm block are used.
               
                  5. Before casting check the slump value of concrete. Take cube for compression strength test.









6. After curing for 7 days start pipe laying. Joint the Butterfly Calve with the Flange pipe. Check the joint thoroughly if there are any defects. 




















7. After installation of valve start re-bar binding as per drawing, finishing re-bar binding go for form setting work. During form setting keep the clear cover as per requirement, use cc block to maintain covering. Cast the concrete with C25, during casting use vibrator properly to prevent formation of void. After 7 days of curing remove form and continue curing as per requirement.


















8. Set the precast top slab and install manhole cover in the site. Elevate the cover according to road level. Don't set the manhole cover too much higher than road level because it causes problem for traffic.
