Author: Edi Supriyanto Email: edisupriyanto@gmail.com WhatsApp: https://wa.me/6281338718071/ Website: https://neurostruct.id/ Abstract The elevator pit, or bottom overrun, is a critical sub-grade structural element that defines the safety and longevity of vertical transportation systems. In tropical regions such as Bali, high groundwater tables and fluctuating hydrostatic pressure pose significant risks to pit integrity, including dampness, reinforcement corrosion, and structural heaving. This paper presents a comprehensive engineering methodology for the design and construction of reinforced concrete (RC) elevator pits. We integrate modern waterproofing techniques with structural load analysis to provide a standard for professional implementation. 1. Introduction The elevator pit serves as the foundation for the rail system and the buffer mechanism. Any deviation in level or structural settlement can lead to catastrophic mechanical failure. In coastal or high-precipitation environments, the ingress of groundwater is the primary failure mode. This study outlines the necessary steps to construct a water-tight, load-bearing pit structure. 2. Structural Design and Load Analysis The pit must be designed to withstand both vertical loads (from the elevator rails and car weight) and lateral earth/hydrostatic pressures. 2.1 Hydrostatic Pressure Calculation For a pit depth ($h$), the lateral hydrostatic pressure ($P$) is defined by the following equation: $$P = \rho \cdot g \cdot h$$ Where: $\rho$ = Density of water (approx. 1000 kg/m³) $g$ = Gravitational acceleration (9.81 m/s²) $h$ = Depth of the pit below the water table (m) The total force ($F$) exerted on the pit wall is: $$F = 0.5 \cdot \rho \cdot g \cdot h^2 \cdot L$$ (Where L is the length of the wall section). 3. Construction Methodology Professional implementation requires adherence to the following specifications: Sub-grade Preparation: Excavation should include a layer of lean concrete (min. 10 cm) to provide a stable working surface. Waterproofing: Application of crystalline waterproofing admixture in the concrete mix, supplemented by a bituminous or sheet membrane applied to the exterior face. Reinforcement: Use of high-yield steel bars ($f_y \geq 400 \text{ MPa}$) with a clear concrete cover of at least 50 mm to prevent corrosion. 4.

Penulis: Edi Supriyanto Email: edisupriyanto@gmail.com WhatsApp: https://wa.me/6281338718071/ Website: https://neurostruct.id/ Abstrak Pit lift (atau lubang dasar elevator) adalah elemen struktural bawah tanah yang krusial yang menentukan keamanan dan umur panjang sistem transportasi vertikal. Di wilayah tropis seperti Bali, muka air tanah yang tinggi dan tekanan hidrostatik yang fluktuatif menimbulkan risiko signifikan terhadap integritas pit, termasuk kelembapan, korosi tulangan, dan penurunan struktural (heaving). Makalah ini menyajikan metodologi teknik komprehensif untuk desain dan konstruksi pit lift beton bertulang (RC). Kami mengintegrasikan teknik kedap air modern dengan analisis beban struktural untuk memberikan standar bagi implementasi profesional. 1. Pendahuluan Pit lift berfungsi sebagai fondasi bagi sistem rel dan mekanisme penyangga (buffer). Setiap penyimpangan pada elevasi atau penurunan struktural dapat menyebabkan kegagalan mekanis yang fatal. Di lingkungan pesisir atau dengan curah hujan tinggi, masuknya air tanah adalah mode kegagalan utama. Studi ini menguraikan langkah-langkah yang diperlukan untuk membangun struktur pit yang kedap air dan mampu menahan beban. 2. Desain Struktural dan Analisis Beban Pit harus dirancang untuk menahan beban vertikal (dari rel lift dan berat kabin) serta tekanan tanah/hidrostatik lateral. 2.1 Perhitungan Tekanan Hidrostatik Untuk kedalaman pit ($h$), tekanan hidrostatik lateral ($P$) didefinisikan dengan persamaan berikut: $$P = \rho \cdot g \cdot h$$ Di mana: $\rho$ = Massa jenis air (sekitar 1000 kg/m³) $g$ = Percepatan gravitasi (9.81 m/s²) $h$ = Kedalaman pit di bawah muka air tanah (m) Gaya total ($F$) yang diberikan pada dinding pit adalah: $$F = 0.5 \cdot \rho \cdot g \cdot h^2 \cdot L$$ (Di mana L adalah panjang segmen dinding). 3. Metodologi Konstruksi Implementasi profesional memerlukan kepatuhan terhadap spesifikasi berikut: Persiapan Sub-grade: Penggalian harus menyertakan lapisan beton kurus (lean concrete, min. 10 cm) untuk menyediakan permukaan kerja yang stabil. Waterproofing: Penggunaan bahan tambahan kedap air (crystalline waterproofing admixture) dalam campuran beton, dilengkapi dengan membran bituminus atau lembaran yang diaplikasikan pada sisi eksterior. Penulangan: Penggunaan baja tulangan bertegangan tinggi ($f_y \geq 400 \text{ MPa}$) dengan selimut beton minimal 50 mm untuk mencegah korosi. 4.
