Hammer crane to drive long reinforced concrete pegs to make a canal wall

In khlong 11 in front of Wat Sa Bua temple they are building a canal wall. This is a market area that now is closed for this job. The jobs in Thailand are primitive and dangerous and takes a long time to finish. Thai concrete infrastructure are very solid I can say that because I've studied 3 years civil engineering and I've also worked of my jobs in big industries building skyscrapers in Sydney and at a Steel Workers BHP in Port Kembla south of Sydney worked as a Rigger.
