Device and method for pit exploration and excavation of highway subgrade
The invention provides a device and method for highway subgrade pit excavation, and relates to the field of geotechnical engineering.The device for highway subgrade pit excavation comprises a support, an axial limiting sleeve rod, a limiting sleeve piece and a scarifier, a horizontal table is arranged on the support, and a through hole for the axial limiting sleeve rod to penetrate through is formed in the middle of the horizontal table; the limiting sleeve piece is installed on the support, matched with the axial limiting sleeve rod structure and used for fixing the axial limiting sleeve rod. One end of a connecting rod of the scarifier is connected with a rocker, the other end of the connecting rod is connected with a tool bit, an axial limiting sleeve rod is of a hollow tubular structure, the connecting rod is sleeved with the axial limiting sleeve rod, and the scarifier is rotationally connected with the axial limiting sleeve rod through a bearing and ascends and descends synchronously with the axial limiting sleeve rod. The tool of the tool bit is arranged around the tool bit supporting column, and the lowest point of the tool bit supporting column is higher than that of the tool. Torque can be effectively transmitted, rotation of the cutter in the excavation process is achieved, the excavation efficiency is guaranteed, and the scarifier can synchronously ascend and descend along with the axial limiting sleeve rod.
本发明提供了一种用于公路路基探坑开挖的装置及方法，涉及岩土工程领域，用于公路路基探坑开挖的装置包括支架、轴向限位套杆、限位套件和松土器，支架上设置有水平台，水平台的中部设置有供轴向限位套杆穿过的通孔，限位套件安装在支架上，与轴向限位套杆结构配合，用于固定轴向限位套杆；松土器的连杆一端连接摇杆，另一端连接刀头，轴向限位套杆为中空的管状结构，连杆套装在轴向限位套杆的内部，松土器通过轴承与轴向限位套杆转动连接并同步升降；刀头的刀具环绕刀头支撑柱设置，刀头支撑柱的最低点高于刀具的最低点。本发明可以有效传递扭矩，实现刀具在开挖过程中旋转，保证了开挖效率，且可以使松土器随轴向限位套杆同步升降。
