Example Embodiment

[0041] Example 1

[0042] like Figure 1-Figure 4 As shown, a static blasting energy gathering device,

[0043] The device includes a main body casing 1 composed of two-lobed arc-shaped steel formwork 1-1, the two-lobed arc-shaped steel formwork 1-1 is not connected, and the midpoint of the two-lobed arc-shaped steel formwork 1-1 The connection line is perpendicular to the pre-splitting line 5; the outside of each arc-shaped steel template 1-1 is provided with a splitting angle 2, and the tip 2-1 of the splitting angle 2 is located on the same straight line as the pre-splitting line 5;

[0044] Both sides of the arc-shaped steel formwork 1-1 are provided with stabilizing shaft guide rings 4 on each side, and a stabilizing shaft 3 is placed on the stabilizing shaft guide rings 4;

[0045] The diameter of the stabilization shaft 3 is 10mm, and it is made of steel or alloy material with greater strength.

[0046] The main body casing 1 is a cylinder with an inner diameter of 3...

Example Embodiment

[0050] Embodiment 2

[0051] A method for blasting using a static blasting energy gathering device, the method comprising the following steps:

[0052] 1) Drilling: Drilling 6 on the rock that needs static blasting;

[0053] 2) Place the static rock splitting energy gathering device: apply a certain amount of lubricating oil on the stabilizer shaft guide ring 4 in advance. In the drill hole 6, first place the main body casing 1 of the static rock splitting energy gathering device, so that each splitting angle 2 The tip 2-1 and the pre-splitting line 5 are located on the same straight line, and then the four stabilization shafts 3 are inserted into the stabilization shaft guide ring 4 to complete the placement of the static rock splitting energy gathering device;

[0054] 3) Filling with rock cracking agent slurry (referred to as static blasting agent in the background art): fill the main body casing 1 of the placed energy gathering device with rock cracking agent slurry and w...

Example Embodiment

[0058] Embodiment 3

[0059] The included angle a of the tip of the splitting angle is selected for the test of 45 degrees, and the test process is as follows:

[0060] When the included angle a is designed to be different degrees, which are 0, 30, 45, 60 and 90 degrees, the large-scale finite element software adina is used to simulate the different force characteristics of the tip of the splitting angle to select the optimal clip horn.

[0061] When there is no splitting angle, the force on the tip of the splitting angle is as follows: Figure 5 shown;

[0062] When the included angle a of the tip of the splitting angle is 30 degrees, the stress on the tip of the splitting angle is as follows: Image 6 shown;

[0063] When the included angle a of the tip of the splitting angle is 45 degrees, the stress on the tip of the splitting angle is as follows: Figure 7 shown;

[0064] When the included angle a of the tip of the splitting angle is 60 degrees, the stress on the ti...

Abstract

The invention discloses a static blasting and energy-gathering device. The static blasting and energy-gathering device comprises a main body protective barrel which is formed by splicing two circular-arc-shaped steel templates which are not connected, wherein a connecting line of middle points of the two circular-arc-shaped steel templates is perpendicular to a pre-splitting line; a splitting angle is arranged on the outer part of each circular-arc-shaped steel template, and the tip end of the splitting angle and the pre-splitting line are positioned on the same straight line. A method for blasting by applying the static blasting and energy-gathering device comprises the following steps: 1) drilling; 2) placing a static stone-breaking and energy-gathering device; 3) pouring stone breaker slurry for breaking stones; 4) recycling. According to the static blasting and energy-gathering device and the blasting method provided by the invention, the problems of long crushing time, high dosage for crushing and the like can be solved, the static crushing and blasting time is shortened, the dosage per crushing volume is reduced, and the crushing efficiency of a static crushing agent is improved.

Description

technical field [0001] The invention relates to the blasting field, in particular to a static blasting energy gathering device and a blasting method thereof. Background technique [0002] With the development of my country's construction industry and the improvement of living environment requirements, static crushing, as an alternative blasting technology for explosive blasting, has attracted more and more people's attention. The advantages of static blasting are safe and effective, silent crushing, no blasting flying rocks, no dust in blasting, no impact on surrounding buildings, and basically no impact on the surrounding environment. Therefore, it has obvious advantages in concrete demolition, rock and ore mining projects in densely populated urban reconstruction projects, projects with cultural relics to be protected around, and other environmental conditions that are not convenient for explosive blasting. With the acceleration of urbanization in our country, the rapid i...
