注浆施工中应注意哪些问题?

答案

参考答案:

(1)操作人员应经常对注浆设备进行彻底的清理、检查,要保证注浆泵能正常工作,注浆管路畅通,压力显示系统准确无误。

(2)保证浆液从管片的对称位置注入,防止产生偏压,使管片发生错台或损坏。

(3)注浆过程中,要密切关注管片的变形情况,若发现管片有破损、错台、上浮等现象应立即停止注浆。

(4)当注浆量突然增大时,应检查是否发生了泄漏或注入掌子面,若发生前述现象,应停止注浆,妥善处理后再继续注入。

(5)注浆过程中若发生管路堵塞,应立即处理,以防止管中浆液凝结,尤其是盾尾暗置管路一定要及时进行清理。

(6)注浆泵上的清洗水箱,应保持有足够的水,以防止污物进入影响泵的使用。

    I stood in the doorway, watching my older brother carefully putting clothes into his bag. I coughed
uneasily. When he realized that I was there, Rocky turned toward me   1   a sad smile.
    "I'm   2   tomorrow," he said. "I know." My   3   was almost a whisper (低声, 耳语). I was angry at 
  4   for being so weak, but I wasn't about to (将要) cry. "My   5   is early, so you haven't enough time to
come to the airport," he said. Seeing the sad look on my face, he quickly added, "I   6   I won't leave without
saying goodbye." 
    I tried to say   7   but didn't. It's always better to   8   if you're about to cry. 
    "You promised you wouldn't cry," he said to me, thinking that I was to cry. I remember the day he
   9   me how to ride a bike. At first I thought he was always right behind me, holding the seat to keep
me from  10 . I was happy with this, but he knew he  11  hold me up all my life. He told me that one day
he would have to leave. His coughing stopped my  12 . What was left to say?  13  could I say goodbye to
the person who taught me everything?
    The next morning I  14 , looked at my alarm clock, and realized he had left  15  before. We never even
said goodbye. 
    Goodbye, Rocky! Although he may have been many miles away, I knew he heard me, even if it was
only an answer in his heart.
