Abstract

The invention discloses a carbon dioxide blaster, which comprises a push rod, a liquid storage pipe and an exhaust pipe. The liquid storage pipe is provided with a liquid storage chamber, the exhaust pipe is provided with an exhaust chamber, and the surface of the exhaust pipe is provided with an exhaust pipe. hole, the exhaust hole communicates with the exhaust cavity, the push rod and the liquid storage pipe are connected through the first connector, the liquid storage pipe and the exhaust pipe are connected through the second connector, and a heater is arranged on the first connector. A constant pressure shearing piece is arranged on the second connecting head, and the constant pressure shearing piece is arranged between the liquid storage chamber and the exhaust chamber. The carbon dioxide blaster can prevent the push rod from detaching and ejecting from the drill hole during blasting, avoiding damage and deformation of the push rod, and is beneficial to the recycling and reuse of the blasting pipe.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a carbon dioxide blaster. Background technique [0002] Subgrade earthwork is one of the key processes of road construction projects. In construction, large hydraulic pick excavators such as 360 and 450 and down-the-hole drills are usually used in conjunction with large hydraulic wedges for construction. Due to the hard mining of some sections, it is difficult to mine. The efficiency is very low, and the construction schedule requirements cannot be met, and the construction cost also increases significantly. In order to ensure the smooth advancement of the construction progress, a new type of stone mining method has been developed: carbon dioxide (CO2) blasting technology. [0003] Liquid carbon dioxide phase change fracturing technology is a blasting technology with advanced concept, safe method and remarkable effect. It belongs to physical blasting technology. It has no...
