声测管对声波透射法检测桩身完整性的影响
|
摘要
基桩作为承担建设工程(工业与民用建筑工程、桥梁工程等)上部荷载的主要构件,其质量直接影响到整体的安全和使用功能。目前工程桩基声波透射法为桩身完整性检测常用方法之一,对桩长较长以及直径较大的桩身完整性检测中具备优势的特点。在现场检测时设备仪器检测能力以及数据采集的可用性非常重要,另外声测管作为检测通道其安装及通管准备工作直接关系到检测的成功与否。列举实例说明其影响结果的事实,声测管的安装及通管欠缺对声波透射法波形的影响,以及补充验证方法。
As the main component bearing the upper load of construction engineering(industrial and civil construction engineering, bridge engineering), the quality of foundation pile will directly affect the overall safety and service functions. At present, the acoustic transmission method of engineering pile foundation is one of common inspection methods for the integrality of pile body, and has the preponderant characteristics for the inspection of the integrality of the pile body with the longer length and lager diameter. This inspection method is required that the inspection capacity and of equipment and the availability of data collection are very important in the field inspection. In addition, the installation and preparation of sounding pipe as the inspection channel are directly related to the success of the inspection. The examples explain the result of its influence, the influence of installation of sounding pipe and shortcoming of pipe on the waveform of acoustic transmission method, and the supplementary verification method.
