沉井基础是以沉井法施工的地下结构物和深基础的一种型式.它由刃脚、井壁、隔墙、井孔、凹槽、射水管组和探测管、封底混凝土、顶盖部分组成.首先在地表制作成一个井筒状的结构物,然后在井壁的围护下,从井内不断挖土,使沉井在自重作用下逐渐下沉,达到预定设计标高后,再进行封底,构筑内部结构.广泛应用于桥梁、烟囱、水塔的基础.
首先,本文将工程概况进行介绍,对当地水文地质进行分析.
其次,本文对当地的环境编写施工方案,介绍其施工工艺;分析沉井施工中的质量通病,如何控制质量通病的发生.
再次,本文沉井施工工艺前期准备工作详细说明;对如何下沉、下沉需注意事项进行详细说明.
最后,对沉井基础在实际应用中的技术和经验加以体会,对经济效益进行分析.

Open caisson foundation is a type of underground structure sinking construction and deep foundation.It consists of a cutting edge,wall,partition wall,hole,groove,a water jet pipe group and the detector tube,concrete cover,cover parts.Firstly,on the surface of the earth,made into a shaft shaped structure,and then from the well digging in the borehole wall under continuous,so that the caisson gradually sinking under its own weight,the intended design elevation,and then carried back to build the internal structure .Widely used in basic bridges,chimneys,cooling towers.
Firstly,this paper overview of the project are introduced,and the local hydrogeological analysis.
Secondly,this paper prepared construction scheme on the local environment,the paper introduces its construction technology; analysis of quality defects in construction of open caisson,how to control the occurrence of common quality defects.Secondly,the local environment to prepare construction plan,introduced its construction process; analysis caisson construction quality defects,how to control the occurrence of quality defects.
Thirdly,the construction technology of caisson preparatory work in detail; how to sink,sink the need to pay attention to detail.
Finally,the experience of open caisson foundation in the practical application of the technology and experience,on the economic benefit analysis.
