Embankment Concrete Gravity Dam Construction Process.
Embankment concrete gravity dams are a type of concrete dam that is constructed by placing concrete in layers on an embankment of compacted earth or rockfill. The embankment provides stability and support for the dam, while the concrete provides strength and impermeability.
The construction process of an embankment concrete gravity dam typically involves the following steps:
1. Site preparation.
The first step is to prepare the site for construction. This includes clearing the area of vegetation and debris, and excavating the foundation to the required depth.
2. Embankment construction.
The embankment is then constructed by placing layers of compacted earth or rockfill on the prepared foundation. The embankment is typically built up in lifts of 6 to 12 inches, and each lift is compacted to achieve the desired density.
3. Concrete placement.
Once the embankment has been constructed to the desired height, the concrete is placed in layers on the embankment. The concrete is typically placed in lifts of 6 to 12 inches, and each lift is allowed to cure before the next lift is placed.
4. Curing.
The concrete is cured by keeping it moist for a period
of time. This allows the concrete to gain strength and achieve its full potential. The curing period typically
lasts for 28 days.
5. Grouting.
Once the concrete has cured, it is grouted to fill any voids or cracks in the concrete. Grouting is typically done by injecting a cement-based grout under pressure into the concrete.
6. Completion.
The dam is now complete and can be put into service. The dam will be monitored regularly to ensure that it is performing as expected.

碾压混凝土重力坝施工工艺流程。

碾压混凝土重力坝是一种混凝土坝，其建造工艺是将混凝土分层压实碾筑在碾压土或堆石料的坝基上。

坝基可提供坝体的稳定性和支撑力，混凝土则提供强度和不透水性。

碾压混凝土重力坝的施工工艺流程通常包括以下步骤：
1. 场地准备。

第一步是为施工做好场地准备工作。

这包括清除场地上的植被
和杂物，并根据要求挖掘地基。

2. 坝基施工。

随后通过在已经准备好的地基上分层碾压夯实土石料，以构建
坝基。

坝基通常分6至12英寸升层构建，每层都会压实以达到预期
的密实度。

3. 混凝土浇筑。

当坝基已建至所需高度后，开始在坝基上分层浇筑混凝土。

混
凝土通常分6至12英寸层浇筑，每一层在浇筑下一层之前都需要充
分养护。

4. 养护。

通过保持混凝土处于湿润状态一段时期来对混凝土进行养护。

这可以让混凝土获得强度并达到其全部潜能。

养护期通常持续28天。

5. 灌浆。

混凝土养护完毕后，通过灌浆来填补混凝土中的空隙或裂缝。

灌浆通常通过在压力下向混凝土内注入水泥浆来完成。

6. 竣工。

至此，坝体已经竣工并可投入使用。

大坝将定期监测，以确保其性能符合预期。
