机械旋挖桩基工程在建筑施工中是一种常用基础形式,在基础施工中占着重要地位,以桩作为建筑物的承载,具有稳定性好、承载能力强、沉降量小、工期短以及易安全操作等特点,被广泛应用在各类高层建筑及工业建筑中。由于机械旋挖成孔过程无法直接观察判定,成桩后也不能进行开挖验收,施工中的任何一个环节出现问题,都将直接影响整个工程的质量和进度,甚至给投资者造成巨大经济损失和不良社会影响。因此必须预防在旋挖和桩身混凝土浇筑过程中,特别是水下混凝土灌注过程中出现的施工质量问题,本文主要就山西灵石东方希望晋中分解槽机械旋挖桩工程施工时遇到的问题及防治措施进行解析。
Mechanical rotary pile foundation engineering is a commonly used basic form in construction, which occupies an important position in the foundation construction. With the pile as the bearing of the building, it has the advantages of good stability, strong carrying capacity, small settlement, short construction period and Easy to operate safely and so on, is widely used in various high-rise buildings and industrial buildings. Due to the mechanical rotary drilling can not be directly observed and determine the process, after the pile can not be carried out excavation inspection, any part of the construction problems, will directly affect the quality and progress of the entire project, and even cause huge economic losses to investors And adverse social impact. Therefore, it is necessary to prevent construction quality problems during the process of pouring and pile concrete pouring, especially in the process of underwater concrete pouring. This paper mainly discusses the construction quality problems encountered by Shanxi Lingshi Oriental Hope Jinzhong Decomposition Slot Mechanical Drilling Pile Construction Problems and prevention measures to resolve.
