Abstract
This article presented a case study on a pipe jacking tunneling project crossing underneath the Bang Prakong River in Thailand. This project belonged to the Thailand Irrigation Department and connected between the Klong Phra Ong Chaiya Nuchit and the Bang Pakong River. The technique and process of tunnel construction crossing the river by pipe jacking method were described in details. Moreover, the technique and process of shaft construction technique for jacking pit and receiving pit by sinking method were explained. The jacking pit was collapsed so it was reversed to be the receiving pit. This pit was rebuilt by the steel casing. Then the new jacking pit was improved from the old receiving by the jet grouting method. The jacking force was controlled under 900 Ton. The horizontal deviation was in between ±60 mm and the vertical deviation was in between ±70 mm along the tunnel line. © 2021 ISSMGE, London, UK
