Abstract

The invention relates to the technical field of rock drilling, in particular to a hand-push type positioning punching trolley for rock-soil drilling. The hand-push type positioning punching trolley for rock-soil drilling comprises a supporting seat and a push-pull handle installed on the supporting seat, and further comprises a supporting shaft and a punching device; the punching device comprises a connecting sleeve, a pile column and a vibration assembly; the vibration assembly comprises a pressure spring and an inertia clamping piece; the inertia clamping piece comprises a trigger ring, an annular rail and two limiting assemblies; and each limiting assembly comprises a limiting groove, a telescopic block and a tension spring. According to the hand-push type positioning punching trolley for rock-soil drilling, before punching of the pile column, the pile column is made to be vertical when stopping swinging in a vibration mode, and the situation that the bearing capacity of the pile column is affected due to punching deflection is prevented.

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...
