Uplift pile construction method without rock blasting

Abstract

The invention discloses an uplift pile construction method without rock blasting which comprises the construction processes of burying a reaction frame of an orifice section, extracting rock cores of the orifice section in a layering manner, and cleaning and chiseling the rock surfaces of the orifice section; erecting a reaction frame of a standard section, extracting rock cores of the standard section in a layering manner, and cleaning and chiseling the rock surfaces of the standard section; erecting a reaction frame of an expanding section, extracting rock cores of the expanding section in a layering manner, and cleaning and chiseling the rock surfaces of the expanding section, and the like. The beneficial effects of the method is that the whole construction work of the orifice section, the standard section and the expanding section can be completed and the big difficulty in expanding section construction is overcome; the speed is fast and the average excavation construction speed of the whole rock stratum can reach 1.2m per day; machinery automation is high; the universality is high; the operation is convenient; the safety, energy conservation and environment protection are realized.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a construction method of non-blasting rock uplift piles. Background technique [0002] With the acceleration of my country's railway, highway and urban infrastructure construction, most of the tunnels are shallowly buried and pass through urban and rural structures and buildings, and the drilling and blasting method is still used in the construction of tunnels in these areas. In order to ensure the safety of surface residents, structures and buildings, blasting vibration control technology must be used in drilling and blasting construction. Even if it is a very advanced blasting vibration control technology, it can only minimize blasting vibration and control fluctuations in blasting vibration velocity. It is highly sensitive and can easily affect residents. When excavating shallow-buried tunnels in an urban environment with many buildings on the surface, non-blasting excavation...

Problems solved by technology

In the prior art, "the construction structure of bored piles adjacent to the existing railway line based on water mill drilling" is suitable for the geological conditions of upper soil and lower rock, and in the construction of pile foundations with the same diameter, it cannot meet the geological conditions of the whole rock. And it cannot meet the construction requirements of the uplift pile with the standard pile diameter on the upper part and the enlarged head on the end
