文章对几种声测管进行了经济性和实用性比选,最终选用了管壁较薄的声测管,同时改进施工工艺,方法是在灌注桩基混凝土前,向声测管内插入硬质柔性塑料管,保证混凝土灌注过程中声测管始终保持通畅,待灌注结束后抽出硬质柔性塑料管,塑料管循环利用。实践结果表明,此种方法质量可靠性大大高于传统的声测管施工工艺,并且节省了大量的资金,提高了施工效率。文章内容包括声测管的优化选用、构造以及施工方法。

In this paper, several acoustic tubes were economically and practically selected, and finally the acoustic tubes with thinner walls were selected. At the same time, the construction process was improved by inserting rigid tubes into the acoustic tubes Flexible plastic pipe to ensure that the process of perfusion of concrete acoustic tube is always open, to be perfusion after the withdrawal of rigid flexible plastic pipe, plastic pipe recycling. Practice shows that the quality and reliability of this method is much higher than the traditional acoustic pipe construction technology, and save a lot of money and improve the construction efficiency. The article includes the optimization of acoustic tube selection, construction and construction methods.
