Abstract

The invention relates to the technical field of rock drilling, in particular to a hand-pushed positioning and drilling trolley for rock and soil drilling. The utility model relates to a hand-push type positioning and punching trolley for geotechnical drilling, comprising a support base, a push-pull handle mounted on the support base, a support shaft and a drilling device. The punching device includes a connecting sleeve, a pile and a vibration assembly. The vibration assembly includes a compression spring and an inertial clip. The inertial clip includes a trigger ring, an annular rail and two limit components. Each limit assembly includes a limit slot, a telescopic block and a tension spring. The hand-pushed positioning and punching trolley used for geotechnical drilling of the present invention vibrates before the pile is drilled to make it more vertical when the pile is stopped, so as to prevent the impact of the pile due to the deflection of the hole. carrying capacity.

Description

technical field [0001] The invention relates to the technical field of rock drilling, in particular to a hand-push positioning and drilling trolley for rock and soil drilling. Background technique [0002] In geotechnical drilling, piles are inserted into the rock and soil. A connecting sleeve is provided outside the pile, and when the connecting sleeve finds a vertical position, the pile is separated from the connecting sleeve to make the pile fall, and then an external force is applied to smash the pile vertically into the rock and soil, and cement can be poured outside the pile to Or cement mortar to increase the bearing capacity of piles. It is difficult for the existing drilling device to find the vertical position in a complicated construction environment, which causes the drilling to be deflected and affects the bearing capacity of the pile. Contents of the invention [0003] The invention provides a hand-push positioning and drilling trolley for rock and soil dri...
