column grouting pump:
1 high degree of mechanization, the need for less labor, simple construction organization.
2 concrete transportation and pouring operation is continuous, the construction efficiency is high, the progress of the project.
3.泵送工艺对混凝土质量要求比较严格，也可以说泵送是对混凝土质量的一次检验 ?。又由于泵送是连续进行的，泵送中混凝土不易离析，混凝土坍落度损失不大， ?因此容易保证工程质量。
3 Pumping Technology for more stringent quality requirements of concrete pumping, can also be said to be a test of concrete quality. Because the pump is continuous, pumping concrete in less segregation, slump loss of concrete is not so easy to ensure the quality of the project.
4 job security.
5.对施工作业面的适应性强，作业范围广，混凝土输送管道可以铺设到其它难以到 ?达的地方，又能使混凝土在一定压力下充填浇注到位，还可以把泵串联使用，以 ?增大输送距离和高度，满足各种施工的要求。
5.The construction work of strong adaptability, wide operating range, the concrete pipeline can be laid to the other to reach to place, and can make the concrete in place under certain pressure filling casting, can also be used to pump in series, increasing transmission distance and height to, meet various construction requirements.
6 interference with other construction machinery. In the pumping and conveying pipe can be applied in other work near industry.
7 in the normal pumping conditions, the concrete in the pipeline transport will not pollute the environment, to achieve civilized construction.
8.在施工布置得当的条件下，能够降低工程造价。Characteristics of the two structural
8 under the condition of proper arrangement of construction, the construction cost can be reduced.
