1．泵送砼的拌制Mixing of pumping concrete

泵送的砼采用商品砼，其要求具体由搅拌站控制。

Product concrete should be used for pumping, and the requirements for it are determined by batch plant.

2．泵送砼的运输Transportation of pumping concrete

1) 泵送砼的运送采用采用砼搅拌运输车，砼搅拌运输车装料前，必须将搅拌桶

内积水倒净，其数量根据实际情况确定。Concrete transport truck should be used for transportation. Before loading, accumulated water in mixer should

be cleaned. The quantity is determined by actuality.

2) 浇筑块体砼基础时，搅拌运输车辆台数控制在8辆左右，浇捣上部结构或杯

形基础时车辆一般为4台，并根据现场的人员情况、实际工作条件，技术要求进行适当调整。When casting block foundation, the number of concrete

transport truck should be controlled within 8. When casting upper structure

or cup-shape foundation, there are always 4 mixers. And it will be properly

adjusted according to person on site, working conditions and technical requirements.

3泵送砼的浇筑Casting of pumping concrete

1) 在砼搅拌运输车到达以前做好现场一切施工准备工作，包括作业平台的搭

设、道路的通畅、施工用具的准备等。All site preparation should be ready before arrival of concrete transport truck, including building of working platform, unblocked road, equipments for construction, etc.

2) 砼搅拌运输车给砼泵喂料前用中高速旋转拌筒，使砼拌合均匀，避免出料的

砼的分层离析。Before feeding, medium- or high-speed rotating mixer should be used to make concrete evenly keeping exceeding concrete from

delamination and eduction.

3) 喂料前做塌落度试验，符合要求后方可喂料。Feeding cannot be carried out

until falling test is made and is in accordance with requirements.
