现浇箱梁桥跨中临时支墩搭设工艺流程

The process of temporary support pier construction for

cast-in-place box girder bridges

The construction process for temporary support piers in the

mid-span of cast-in-place box girder bridges is an

important aspect of bridge construction. In this process,

several key steps need to be followed to ensure safety and

efficiency. Here is an outline of the typical workflow

involved in the construction of temporary support piers.

1. Site preparation

Before starting the construction of temporary support piers,

the site needs to be properly prepared. This involves

clearing the area and ensuring adequate accessibility for

equipment and materials. It is important to survey the site

and make sure it meets all safety requirements.

准备。在开始临时支墩的施工之前，需要对施工现场进行适当的准

备工作。这包括清理场地，并确保设备和材料能够顺利进入施工区

域。重要的是对现场进行勘测，并确保满足所有安全要求。

2. Temporary pier design

Once the site is ready, the next step involves designing

the temporary support piers. The design should consider

factors such as load-bearing capacity, stability, and

constructability. The design should be reviewed and

approved by a qualified engineer or structural expert

before proceeding with further construction activities.

中文翻译：现场准备完成后，下一步是设计临时支墩。设计应考虑

到承载能力、稳定性和可施工性等因素。在继续进行后续施工活动

之前，设计应由合格的工程师或结构专家进行审查和批准。

3. Foundation preparation

The construction of temporary support piers requires a

solid foundation to ensure stability during construction.

The foundation should be excavated and leveled properly

according to the design specifications. Reinforcement bars

should be placed and anchored securely in the foundation.

中文翻译：临时支墩的施工需要一个坚实的基础以确保在施工过程

中的稳定性。根据设计规范，基础应进行适当的挖掘和平整处理。

钢筋应被放置并安全地固定在基础中。

4. Formwork installation

Once the foundation is ready, formwork needs to be

installed around it to shape the temporary support piers.

The formwork should be properly aligned and secured to

ensure accurate dimensions and shape. It is important to

verify the stability of the formwork before proceeding with

concrete pouring.

中文翻译：一旦基础准备好，需要在其周围安装脚手架来塑造临时

支墩。脚手架应正确对齐并加固，以确保准确的尺寸和形状。在进

行混凝土浇筑之前，验证脚手架的稳定性非常重要。

5. Concrete pouring

After the formwork is prepared, concrete can be poured into

it to create the structure of the temporary support piers.

The concrete mix should meet the required strength and

workability specifications. Adequate consolidation and

vibration techniques should be employed to ensure proper

compaction of the concrete.

中文翻译：脚手架准备好后，可以将混凝土倒入其中以形成临时支

墩的结构。混凝土配合比应符合所需的强度和工作性能规范。应采

用足够的压实和振动技术，确保混凝土得到适当的压实。

6. Curing and post-construction activities

After the concrete is poured, it needs to be properly cured

to achieve optimal strength development. This involves

applying curing compounds or using other methods such as

moist curing. Once the concrete has achieved sufficient

strength, formwork can be removed, and any finishing

touches or adjustments can be made if necessary.

中文翻译: 在混凝土浇筑完成后，需要进行适当的养护以达到最佳

强度发展。这包括施用养护剂或使用其他方法如湿养护等。一旦混

凝土达到足够的强度，可以拆除脚手架，并根据需要进行任何精加

工或调整处理。

This is a typical workflow for the construction of

temporary support piers in the mid-span of cast-in-place

box girder bridges. It is important to follow all safety

guidelines and consult with qualified professionals

throughout each step of the process to ensure a successful

and safe construction project.

这是一个关于现浇箱梁桥跨中临时支墩搭设的典型工艺流程。在整

个流程中，遵守所有安全准则并咨询合格的专业人士非常重要，以

确保施工项目的成功和安全。
