Embodiment 1

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

[0043] The device includes a main casing 1 composed of two arc-shaped steel formworks 1-1, the two arc-shaped steel formworks 1-1 are not connected, and the midpoint of the two-valve arc-shaped steel formwork 1-1 The connecting line is perpendicular to the pre-splitting line 5; a splitting angle 2 is provided on the outside of each arc-shaped steel formwork 1-1, 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 template 1-1 are respectively provided with a stabilizing shaft guide ring 4, and a stabilizing shaft 3 is placed on the stabilizing shaft guiding ring 4;

[0045] The stable shaft 3 has a diameter of 10mm and is made of steel or a stronger alloy material.

[0046] The main body casing 1 is a cylinder with an inner diameter of 36mm, an outer diameter of 40mm, and an axial length of...

Embodiment 2

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

[0052] 1) Drilling: Drilling 6 holes on rocks that require static blasting;

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

[0054] 3) Filling the rock-cracking agent slurry (the static blasting agent referred to in the background technology): fill the rock-cracking agent slurry in the main casing 1 of the placed energy-gathering device, and wait for the rock-crack...

Embodiment 3

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

[0060] The included angle a is designed to be different degrees, when they are 0 degrees, 30 degrees, 45 degrees, 60 degrees and 90 degrees respectively, the large-scale finite element software adina is used to simulate the different force characteristics of the tip of the splitting angle, so as to select the optimal clamping angle horn.

[0061] When there is no splitting angle, the stress 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 degr...

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...
