Asphalt pavement large core sample drilling method
The invention relates to the technical field of highway engineering, in particular to an asphalt pavement large core sample drilling method. The method comprises the following steps: firstly, determining a drilling position of a large core sample and drilling positions of at least two small core samples; the circle where the drilling positions of the two small core samples are located is tangent to the circle where the drilling position of the large core sample is located. And cutting the road surface according to the drilling position of the large core sample and the drilling positions of the at least two small core samples. And taking out the two small core samples and then taking out the large core sample. The method comprises the following steps: firstly, taking out a small core sample with light weight through a clamp; and after the two small core samples are taken out, a cavity is left on the side surface of the large core sample after the two small core samples are taken out. And the two holes facilitate the stretching of tools such as a crowbar into the bottom of the large core sample to loosen the large core sample, so that the large core sample can be taken out conveniently. Meanwhile, the core sample is taken out from the side surface or the bottom of the large core sample, so that the top of the large core sample can be prevented from being damaged, and the integrity of the core sample is ensured.
本发明涉及公路工程技术领域，具体而言，涉及一种沥青路面大型芯样钻取方法。其先确定大型芯样的钻取位置和至少两个小型芯样的钻取位置。两个小型芯样的钻取位置所在圆相切于大型芯样的钻取位置所在圆。按照大型芯样的钻取位置和至少两个小型芯样的钻取位置对路面进行切割。取出两个小型芯样后再取出大型芯样。本发明的方法先通过夹钳将重量较轻的小型芯样取出。当两个小型芯样取出后，大型芯样的侧面即留下两个小型芯样取出后的空洞。两个空洞方便了撬棍等工具伸入大型芯样的底部对其进行松动操作，进而方便将大型芯样取出。同时，从大型芯样的侧面或者底部将其取出能够避免对大型芯样的顶部产生损坏，保证了芯样的完整性。
