Features

The first phase of Guangzhou Metro Line 14 is the first large-scale and long-distance viaduct. In the first phase of Guangzhou Metro Line 14, the rock stratum is broken, the rock surface fluctuates greatly, and there are karst caves and broken zones in some positions. Using one pile-advance geological drilling to identify the bearing layer at the bottom of the pile and large-scale rotary drilling pile to form holes can not only effectively solve the mud pollution, but also improve the construction progress of pile foundation.

In view of the potential safety risks such as ground subsidence caused by pile foundation construction in karst areas, measures such as following up the whole pile casing to the rock stratum, pouring concrete at the bottom of the pile casing, throwing rubble and adding yellow mud, and grouting reinforcement in shallow soil-dissolving tunnels are taken during the construction process to ensure the construction safety. At the same time, strengthen pile foundation detection to ensure the quality of pile foundation and the safety of bridge structure.

the first phase of Guangzhou metro line 14 is laid along guangcong road, which is a national highway, and the construction site is too small to meet the construction land poured on site. According to the on-site construction conditions and the requirements for the appearance quality of viaducts along the national highway, Guangzhou Metro adopts precast segmental erection to reduce the on-site construction time and the influence of dust and noise on the surrounding area.
