海仑宾馆地下-10m深的基础工程,国外原设计者确定桩基采用H型钢桩,地下围护采用钢板桩。他们认为这个方案技术上先进,质量上有保证,工期可以大大缩短。虽然投资成本高一点,但是从宾馆早日投入营业这一点来看,即使多花些钱也是合算的。对于这些观点,我们建设单位认为:就海仑宾馆的特殊地理位置而言,H型钢桩虽较原先的钢管桩有较大改进,但是要实施这个方案也十分困难。因为工地周围的环境十分复杂,如果在施工中出了事故,无论抢修和赔偿均要有一定的时间和精力去处理,这样就可能把原方案缩短工期的优势丧失,而且必将造成工程投资的加码和损失。为了吸取有关工程基础施工的教训,更好地贯彻市和区政府领导的指示,保护工地周围道路和地下管线,减少对工地附近房屋设施的影响,经建设单位、设计单位和施工单位反复推敲,最后决定桩基采 The underground construction of the Hailun Hotel is at a depth of -10m, and the original foreign designers decided to use H-shaped steel piles for the pile foundation and steel sheet piles for the underground enclosure. They believe that this program is technologically advanced, quality assured, and the duration can be greatly shortened. Although the investment cost is a little higher, from the point of view of the hotel being put into operation as soon as possible, it would be cost-effective to spend even more money. For these viewpoints, our construction company believes that, in terms of the special geographical location of the Hailun Hotel, the H-shaped steel piles have been greatly improved compared with the original steel piles, but it is also very difficult to implement this plan. Because the environment surrounding the construction site is very complicated, if an accident occurs during construction, both the repair and compensation must have a certain amount of time and energy to deal with. This may result in the loss of the advantage of shortening the construction period of the original plan, and it will inevitably cause investment in the project. Overweight and loss. In order to learn lessons about the basic construction of the project, better implement the instructions of the leaders of the municipal and district governments, protect the roads and underground pipelines around the construction site, and reduce the impact on the housing facilities near the construction site, the construction unit, design unit, and construction unit repeatedly scrutinized. Finally decided pile foundation mining
