背景

某办公楼工程,建筑面积82000m2,地下3层,地上22层,钢筋混凝土框架剪力墙结构,距邻近六层住宅楼7m。地基土层为粉质黏土和粉细砂,地下水为潜水,地下水位-9.5m,自然地面-0.5m。基础为筏板基础,埋深14.5m,基础底板混凝土厚1500m,水泥采用普通硅酸盐水泥,采取整体连续分层浇筑方式施工。基坑支护工程委托有资质的专业单位施工,降排的地下水用于现场机具、设备清洗。主体结构选择有相应资质的A劳务公司作为劳务分包,并签订劳务分包合同。

合同履行过程中,发生下列事件:

事件一:基础支持工程专业施工单位提出基坑支护降水采用“排桩+锚杆+降水井”的方案,施工总承包单位要求多提出几种方案进行比选。

事件二:底板混凝土施工中,混凝土浇筑从高处开始,沿短边方向自一端向另一端进行。在混凝土浇筑完12h内对混凝土表面进行保温保湿养护,养护持续7d。养护至72h时,测温显示混凝土内部温度70℃,混凝土表面温度35℃。

事件一中,适用于本工程的基坑支护降水方案还有哪些?

答案

参考答案:

本项目为一类深基坑,支护方式只能是排桩或地下连续墙;由于深度较深且离既有建筑较近,变形要求高,必须增加内支撑或设锚杆;由于地下水位在基底以上,如采用排桩需增加如止水帷幕的止水措施,并辅以降水井(如采用地下连续墙,无需考虑止水,仅需降水)。

Superman, Spider-Man, Batman and Iron Man ... .There is no shortage of superheroes. You find them in comic books, on the TV and the big screen.

In a survey of fans by the sci-fi and fantasy website, SFX.co.uk, Batman, 70 years old this year, was voted Britain's favorite superhero.

Unlike many crime-fighting superheroes Batman has no special powers. He can't fly like Superman or shoot a sticky web like Spider-Man.

Bruce Wayne is born to a wealthy Gotham City business family. However, when his parents are murdered his life changes completely.

Wayne feels anger at their deaths and guilty that he did not prevent them. He travels around the world learning how to fight. Upon returning to Gotham, he creates a disguise (伪装) to enable him to fight crime without being recognized.

A childhood fear of bats leads him to choose to dress as one. His idea is that through the bat person he can prove to himself that he has overcome his childhood fears.

Wayne is the CEO of the company he inherits (继承) from his father. He seems to live the lifestyle of a millionaire playboy. But this is a ruse (计策). He works hard at the image to allow himself the freedom he needs to do his work as a crime fighter. "Bruce Wayne, playboy" is the disguise Batman is the real person.

"Wayne is not a born superhero. Instead, he is a real, complex person," said Dace Golder, editor of the website. "He is the most realistic of all the superheroes. I am particularly interested in the emotional process by which a boy becomes a hero. His superhero qualities come from within."
