(二)

某城市桥梁工程,采用钻孔灌注桩基础,承台最大尺寸:长8m、宽6m、高3m,梁体为现浇预应力钢筋混凝土箱梁。跨越既有道路部分,梁跨度30m,支架高20m。
桩身混凝土浇筑前,项目技术负责人到场就施工方法对作业人员进行了口头交底,随后立即进行1号桩桩身混凝土浇筑,导管埋深保持在0.5~1.0m。浇注过程中,拔管指挥人员因故离开现场。后经检测表明1号桩出现断桩。在后续的承台、梁体施工中,施工单位采取了以下措施。
(1) 针对承台大体积混凝土施工编制了专项方案,采取了以下防裂缝措施:
1) 混凝土浇筑安排在一天中气温较低时进行。
2) 根据施工正值夏季的特点,决定采用浇水养护。
3) 按规定在混凝土中适量埋入大石块。
(2) 项目部新购买了一套性能较好、随机合格证齐全的张拉设备,并立即投入使用。
(3) 跨越既有道路部分为现浇梁施工,采用支撑间距较大的门洞支架,为此编制了专项施工方案,并对支架强度作了验算。
问题

施工单位在张拉设备的使用上是否正确说明理由。

答案

参考答案:

解析:施工单位在张拉设备的使用上不正确,因为张拉机具应与锚具配套使用,并应在进场时进行检查和校验。

Sometimes children do not do what their parents tell them to do. When this happens, a parent tries to help the child to do the right thing. When this does not work, the parent usually punishes the child.

There are many things that a parent can do. One thing that people have done is to spank (打屁股) the child. When a parent spanks a child, they will use their hand or a hard object to strike them on their bottom. This is meant to show the child that they have done something wrong.

One parent remembers being spanked when he was a child. His parents used a wooden spoon. When he spanked his own children with his hand, he saw that he put a red mark on his child’s leg. He never did that again.

One problem with spanking is that it teaches the child to hit someone when they do not like what the other person is doing. Another problem with spanking is that the parent is usually angry and can hit the child too hard. Sometimes parents will use spanking for everything and not try other ways to get the child to do the right thing.

Many parents are not sure of what to do instead of spanking. Some people think that their religion tells them that spanking is okay. Some think that the law lets them do it. The courts (法院) say that parents have the right to teach their children how to behave.

Other things should be tried before a parent decides to spank a child. Telling the child exactly what is wanted from them can be one thing. Giving a child more than one choice is another thing that can be tried. Getting down to the child’s level and taking a more child-friendly approach (方法) can help as well.
