     Uncle Li and Uncle Wang are good friends. They live next to each other and their farms are both at the
foot of the mountain. So they can help each other. But neither of them likes to use his head. They're both
poor though they work hard. Most villagers have built new houses, but they still live in the low and broken
houses. They never find out why.Once Uncle Li went to town to buy some medicine for his wife. In the
town he heard the apples in a city were expensive. He told Uncle Wang about it as soon as he went back.
They decided to carry some apples to the city. They borrowed some money from their friends and bought
nearly 1,000 kilograms of apples in the villages and carried them to the city on a tractor. Bad luck! A lot of
apples have already been carried there when they arrived. A few days later they had to sell them at a low
price (价格).They felt unhappy and returned to their village. 
     "I can't understand why we sustained (蒙受) losses in business while others always profit (盈利)"
Uncle Li asked one day.     
     "The tractor was too small" Uncle Wang said without thinking. "We'll carry more apples on a truck
next time!" 
     "I agree!" said Uncle Li. "How foolish we were!"

某承包人承接了一座大桥工程,该桥采用φ1.6m的桩基础,桩长25~32m;桥位处地层均为天然砂砾,地下水位在原地面下约1.5m处。其桩基主要施工过程如下:
平整场地、用水准仪进行桩位放样、埋设钢护筒、选用正循环回旋钻机作为成孔钻机,终孔检查合格后,采用抽浆法进行清孔排渣;根据《公路工程质量检验评定标准》对成孔的孔位、孔深、孔径及泥浆相对密度检验合格,孔底沉淀厚度检验合格。
钢筋笼骨架在现场分段制作、吊装、搭接焊接长、钢筋笼放入孔内,然后将导管沉放到距桩底0.25m处,开始灌注水下混凝土。在灌注混凝土过程中,导管埋入混凝土的深度在1m以内。在距桩顶5m处发生堵管,施工人员采用了转动导管的方法试图疏通导管。
为了减小混凝土灌注过程中因混凝土初凝导致导管堵塞的风险,经施工单位项目总工同意,在混凝土中掺入了适量的缓凝剂,混凝土的坍落度为16cm。
[问题]
