Novel semi-automatic drilling construction device

A novel semi-automatic drilling construction device comprises a base, a sleeve arranged on the base, an electric push-pull rod arranged in the sleeve and on the base, a push-pull rod with the lower portion inserted into the sleeve and an electric drill fixing device arranged on the top face of the push-pull rod, the electric drill fixing device comprises a U-shaped support, and a clamping device is arranged between the upper portions of the two side walls of the U-shaped support. The clamping device comprises at least two screws, and the space between the two screws is an electric drill fixing space. The construction method can better adapt to construction of embedded steel bars at narrow and small positions of a working face, especially adjacent edge positions on the two sides, reduces investment of materials and manpower for erecting an operation frame, and meanwhile reduces operation and construction difficulty of workers. 一种新型半自动钻孔施工装置，包括底座，设于底座上的套筒，内置在套筒内、底座上的电动推拉杆，下部插接在套筒内的推拉杆，以及设于推拉杆顶面的电钻固定装置，电钻固定装置包括U
