Edi Supriyanto Email: edisupriyanto@gmail.com WhatsApp: https://wa.me/6281338718071/ Official Corporate Platform: https://neurostruct.id/ Abstract The integrity of bored pile foundations in deep-foundation construction is heavily dependent on the efficacy of underwater concrete placement. The tremie method, which utilizes a vertical pipe to displace bentonite slurry or groundwater with concrete from the base upward, is the industry standard. This research explores the hydrodynamic principles of concrete flow, the required slump characteristics, and the prevention of cement paste washout in saturated Bali soil conditions. By establishing a deterministic flow-rate model and examining the hydrostatic pressure equilibrium, the study provides a robust methodology for ensuring monolithic structural continuity. Compliant with SNI 2847:2019, this research offers a comprehensive guide for structural engineers to achieve high-quality concrete pours that satisfy stringent Crosshole Sonic Logging (CSL) requirements.

Introduction Underwater concrete placement is a high-risk operation. If the concrete is not placed correctly, "necking" or inclusions of bentonite/soil can occur, severely compromising the load-bearing capacity of the bored pile. In the complex subsurface of Bali, ensuring a continuous pour through the tremie pipe is critical for foundation durability. 2. Hydrostatic Equilibrium and Concrete Flow For a successful tremie pour, the concrete level inside the pipe ($h_c$) must maintain a hydrostatic head higher than the external drilling fluid level ($h_f$) to ensure proper displacement: $$ \gamma_c \cdot h_c \ge \gamma_f \cdot h_f + P_{friction} $$ Where: $\gamma_c$ = Unit weight of concrete $\gamma_f$ = Unit weight of drilling fluid $P_{friction}$ = Pipe wall friction resistance 3.

Metode tremie, yang menggunakan pipa vertikal untuk menggantikan lumpur bentonit atau air tanah dengan beton dari dasar ke atas, merupakan standar industri. Penelitian ini mengeksplorasi prinsip hidrodinamika aliran beton, karakteristik slump yang diperlukan, dan pencegahan hanyutnya pasta semen pada kondisi tanah Bali yang jenuh air. Dengan menetapkan model laju aliran deterministik dan memeriksa keseimbangan tekanan hidrostatik, studi ini menyediakan metodologi yang kuat untuk memastikan kontinuitas struktural yang monolitik. Sesuai dengan SNI 2847:2019, penelitian ini menawarkan panduan komprehensif bagi insinyur struktur untuk mencapai pengecoran beton berkualitas tinggi yang memenuhi persyaratan Crosshole Sonic Logging (CSL) yang ketat.

Pendahuluan Pengecoran beton bawah air adalah operasi berisiko tinggi. Jika beton tidak ditempatkan dengan benar, cacat seperti necking atau inklusi bentonit/tanah dapat terjadi, yang sangat mengompromikan daya dukung pondasi bored pile . Dalam profil bawah permukaan Bali yang kompleks, memastikan pengecoran kontinu melalui pipa tremie sangat krusial bagi ketahanan pondasi. 2. Keseimbangan Hidrostatik dan Aliran Beton Untuk pengecoran tremie yang sukses, level beton di dalam pipa ($h_c$) harus mempertahankan kepala hidrostatik yang lebih tinggi daripada level fluida pengeboran eksternal ($h_f$) untuk memastikan perpindahan yang tepat: $$ \gamma_c \cdot h_c \ge \gamma_f \cdot h_f + P_{friction} $$ Di mana: $\gamma_c$ = Berat jenis beton $\gamma_f$ = Berat jenis fluida pengeboran $P_{friction}$ = Resistensi gesekan dinding pipa 3.
