| Title | Influence of H-Piles Wall on Excavation Safety | ||
| Keyword | |||
| Abstract | In order to investigate the impact of H-piles wall construction method on the safety in and after the construction, a site is chosen, using H-piles wall construction, in Tamsui district for investigation and research. Through the analysis of actual case, its design, planning and installation are investigated and studied. However, even with detailed design and planning , there is still unexpected destruction in Tamsui site, such as slang and subsidence in spill containment base and fence. Fortunately, the destruction is not large-scale and does not cause damage. After a comprehensive review, excluding the influence of factors, such as rain and groundwater, the reason for the occurrence of damage in Tamsui site is the wrong choice of the construction method when the pile was encountered in the process of piling, and excessively relied on the water jetting method which caused long-term and high-pressure water pouring and led to the hollowing out and subsidence. As a result of the study, such accidents can still be prevented by means of management. With controlling the piling time and the action of interval as encountering big stone, we can more accurately grasp the size of stone and other geological information. Changing the steps or methods of construction opportunely, the accidents that have negative effect on safety can be avoided. The purpose of this research is to make the H-piles wall construction safer and more economical by the methods of management that are advised. |
