桩基础是建筑工程中一种常用的基础形式,是深基础的一种。按承载力性状分类为摩擦型桩和端承型桩;按桩身材料可分为混凝土桩、钢桩、组合材料桩等;按成桩方法分类为非挤土桩、部分挤土桩及挤土桩。建筑工程桩基础不论采用何种类型的桩,施工测量都是不可缺少的。建筑工程桩基础施工测量的主要任务:一是把设计总图上的建筑物基础桩位,按设计和施工的要求,准确地测设到拟建区地面上,为桩基础工程施工提供标志,作为按图施工、指导施工的依据。二是进行桩基础施工监测。三是在桩基础施工完成后,为检验施工质量和为地面建筑工程施工提供桩基础资料,需要进行桩基础竣工测量。在很多的工程建设中,由于测量工作未作好,给项目建设带来了各种不必要的损失。本文结合“汉飞又一城”项目介绍桩基工程桩基施工桩位测量质量通病的原因以及对该问题的防治办法。
Pile foundation is a common form of construction, is a kind of deep foundation. According to the characteristics of bearing capacity, it is classified as friction-type pile and end-bearing pile. According to the pile material, it can be divided into concrete pile, steel pile and composite material pile. According to pile-forming method, it is classified as non-soil pile, Soil pile. No matter what kind of pile is used in the construction pile foundation, the construction survey is indispensable. Construction of the main tasks of the pile foundation construction survey: First, the design of the total map of the building foundation pile, according to the design and construction requirements, accurate measurement set to the proposed area on the ground for the construction of the pile foundation to provide a sign, As a basis for construction, guiding the construction of the basis. The second is to carry out pile foundation construction monitoring. Thirdly, after the construction of pile foundation is completed, in order to check the construction quality and provide foundation information for the construction of ground construction, it is necessary to carry out pile foundation completion survey. In many projects, due to the lack of measurement work, the project construction has brought a variety of unnecessary losses. In this paper, “Han Feiyoucheng” project introduced pile foundation pile foundation construction pile quality measurement of common causes and the prevention and treatment of the problem.
