Project Data
- Project : Davao City Coastal Road Bago-Aplaya Section - Segmental Block Retaining Wall
- Year of construction : 2017 – on going
- Client : Department of Public Works and Highways – Region XI.
- Material : TenCate Miragrid® GX Geogrid
Introduction:
The Davao City coastal road bypass project will traverse from Roxas Avenue to Bago Aplaya, cutting through NHA Kadayawan Homes, Matina Aplaya, and Bolton Isla. Three roundabouts (or rotundas) will be installed in the 35-kilometer coastal stretch at Roxas Avenue, Times Beach area, and Matina Aplaya. Increasing population and continuous development of the Davao Region leads to the worsening traffic congestion within its major roads. The coastal road project will definitely abate and address the traffic congestion within the city.
Problem:
The Bago-Aplaya Section facing Davao Gulf going to Talomo is an elevated highway with a 90 degree vertical slope on both sides. The contractor then needs to stabilized and reinforced the embankment effectively.
Solution:
Segmental block wall reinforced with TenCate Miragrid® GX Geogrid was chosen for the final design of the project for its fast, durable, aesthetics and cost effective construction. Reinforced segmental block wall system consists of precast concrete blocks stocked to form the wall facing, with the soil/sand backfill behind reinforced with Miragrid®GX Geogrid. The blocks are moulded with an interlocking mechanism that allows them to firmly interconnected. The geogrid reinforcement laid horizontally in the soil backfill, is connected to the concrete blocks via the interlocking mechanism at specific design heights of the wall. The construction of the reinforced segment block wall system provides a relatively flexible structure that can tolerate differential settlement without causing distress to the structure.
