随着我国人口不断增长和城市化建设进程的持续推进,要求房屋建筑用地节约化和耕地保护,特别是对于丘陵地区的城市建设,尽量选择荒地贫坡是大势所趋。怎样解决好山地条件下的建筑基础施工就日现重要。根据不同地区岩土地质条件,需要因地制宜的设计和解决地基基础施工。对于在山地花岗石岩层条件中的人工挖孔桩施工,现结合本人工作实践,浅谈群桩爆破作业对桩芯混凝土质量保证的施工技术。
With the continuous population growth and the continuous progress of urbanization in our country, it is required to conserve the land for house construction and the protection of cultivated land. Especially for the urban construction in the hilly areas, it is the general trend to try to choose the poor slope. How to solve the construction of the mountain under the conditions of the foundation construction is an important day. According to geotechnical conditions in different areas, the need to design and solve the local conditions based on the foundation construction. For the construction of artificial digging piles in the condition of mountainous granite rock formation, the construction technology of the pile core concrete quality assurance in connection with the working practice of my own group is discussed briefly.
