Water pressure blasting structure

Abstract

The invention discloses a water pressure blasting structure which comprises a shot hole, a water bag and a frame body. A satchel charge is arranged in the shot hole, the water bag is arranged in the frame body, and the frame body and the water bag are arranged in the shot hole. A plurality of rollers are arranged at the top and the bottom of the frame body, multiple cylinder springs are arranged at one end or two ends of the frame body, and the ends, away from the frame body, of the cylinder springs are connected with elastic pads. The water pressure blasting structure can have a protection effect on the water bag, the water bag is prevented from being broken, and the working efficiency of charging the water bag into the shot hole is greatly improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic blasting, and more specifically relates to a hydraulic blasting structure. Background technique [0002] Hydraulic blasting is a tunnel blasting method that has emerged in recent years. It uses water as an intermediate medium to transmit explosion pressure to destroy the tunnel rock mass, and it is a blasting method that can effectively control air shock waves, flying stones and noise. The explosives used in tunnel blasting are the same as those in conventional blasting, and the lead wires are also drawn out from the boreholes where the explosive packs are placed. superior. Water pressure blasting is adopted by more and more blasting projects due to the saving of explosives, low impact on the environment, low noise and good controllability. However, the water bags currently used in hydraulic blasting are still ordinary water bags, which are filled with water and stuffed into the blast hole. Be...

AI Technical Summary

Problems solved by technology

However, the water bags currently used in hydraulic blasting are still ordinary water bags, which are filled with water and stuffed into the blast hole. Because the inner wall of the blast hole is uneven and most of them are sharp rock masses, the water bag is easy to be cut, and the outside of the water bag The diameter is almost the same as the inner diameter of the blast hole, so when inserting it into the blast hole, it needs to be inserted carefully and slowly, and the working efficiency is low

[0003] Patent number: CN201610713505.1, patent name: In the invention patent of a new type of deep hole hydraulic blasting device and blasting method, hydraulic blasting is also used, in which the water bag is divided into an inner water bag and an outer water bag, and the inner water bag is Place the explosive cartridge, fill the outer water bag with water, and put the water bag directly into the blast hole with uneven surface. Although there are regular protrusions on the outer wall of the outer water bag, the protrusions are hollow and in line with the outer water. The bags are connected and connected, and the water bag is equipped with explosive cartridges. The water bag is heavy, and it is easy to be cut by sharp objects on the inner wall of the blasthole when it enters the blasthole. The protrusion on the surface of the outer water bag cannot fundamentally solve the problem of the water bag The problem of being scratched
