Two EPBMS ready for Bangkok flood prevention project

Representatives from the Department of Drainage and Sewerage BMA and contractor Italian Thai-Nawarat Joint Venture joined TERRATEC via an online link in the celebration of the successful Factory Acceptance Test of a new 6.49m diameter EPBM destined for the Khlong Prem Prachakorn Drainage Tunnel Project in Bangkok, Thailand. The second Factory Acceptance Test for another EPBM will take place in early Jan. 2023.

The two new TBMs will be used to build a water draining tunnel that is 13.3km long and 5.7m-wide, running from Klong Bang Bua to the Chao Phraya River. In addition to this tunnel, a water pumping station will be built along with a water draining building and four water receiving buildings.

To accommodate the alignment requirements of the project, the TERRATEC machines are designed with active-type articulation that can accommodate the minimum radius curve of 50m and 25m.

The geological conditions along the tunnel alignments will consist of soft, medium, stiff sandy clay & sand and therefore the TBM’s soft ground cutterhead features a flat spoke type with copy cutters.

Traditionally reinforced, 300mm thick by 1400m wide, Universal reinforced concrete segments (5 + 1) will be installed as the machine progresses.

Muck removal, segment transport and supply of consumables will be via rail-bound equipment using battery locomotives.

Designed to improve water management in Thai capital, Bangkok from floods when it rains heavily, the project is to build a water pumping station and water draining buildings.

Following the successful factory acceptance test, TBM S101 has already been delivered in December. The second TBM S100 will be shipped to Thailand and will arrive in early 2023. The two TBMs will then be transported to the project site where they will be launched in mid of 2023.
