     Baseball is America's national sport. So it is not unusual that many popular expressions come from baseball.

But first, let me explain a little about the game.

     Each baseball team has nine players. The pitcher of one team throws the ball to a batter from the other team.

The batter attempts to hit the ball. If he misses, it is called a strike. If a batter gets three strikes, he loses his

turn at bat and is called out. The batter also is out if he hits the ball in the air and an opposing player catches it.

But if the batter hits the ball and it is not caught, the batter tries to run to one or more of the four bases on the

field. The batter can run to all four bases if he hits the ball over the fence or out of the ballpark. Such a hit is

called a homerun.

     Now, here are some common expressions from baseball. Someone who is "on the ball" is intelligent and able

to do a good job. But a person who "threw a curve ball" did something unexpected. Someone who "steps up to

the plate" is ready to do his or her job. A "pinch hitter" takes the place of someone else at a job or activity.

     Sometimes I have to give information quickly, without time to think it over. Then I would say something

"right off the bat". If someone is doing an extremely good job and is very successful,you might say he or she is

"batting one thousand."

     If I say I want to "touch base" with you, I will talk to you from time to time about something we plan to do.

I might say I "touched all the bases" if I did what is necessa- ry to complete a job or activity. And if I "covered

my bases" I was well prepared. However,someone who is "way off base" did something wrong or maybe even

dishonest or immoral. A person with strange ideas might be described as "out in left field".

     Finally, when a situation changes completely, we say "that is a whole new ballgame."

某大型顶进箱涵工程为三孔箱涵，箱涵总跨度22m，高5m，总长度33.66m，共分三节，需穿越5条既有铁路站场线；采用钢板桩后背，箱涵前设钢刃脚，箱涵顶板位于地面以下0.6m，箱涵穿越处有一条自来水管需保护。地下水位于地面以下3m处。箱涵预制工作坑采用放坡开挖，采用轻型井点降水。
项目部编制了轨道加固方案，采用轨束梁加固线路，以保障列车按正常速度行驶；制定了顶进时对桥(涵)体各部位的测量监控方案，经项目部技术负责人批准后实施。
按原进度计划，箱涵顶进在雨期施工前完成。开工后，由于工作坑施工缓慢，进度严重拖后。预制箱涵达到设计强度并已完成现场线路加固后，顶进施工已进入雨期。项目部加强了降排水工作后开始顶进施工。为抢进度保工期，采用轮式装载机直接开入箱涵孔内铲挖开挖面土体，控制开挖面坡度为1:0.65，钢刃脚进土50mm；根据土质确定挖土进尺为0.5m，并且在列车运营过程中连续顶进。
箱涵顶进接近正常运营的第一条线路时，遇一场大雨。第二天，正在顶进施工时，开挖面坍塌，造成了安全事故。
问题

指出项目部编制的轨道加固与测量监控方案及实施过程存在的问题，并写出正确做法。
