Abstract
The invention belongs to the technical field of static crushing and particularly relates to a method used for controlling rock or concrete crushing modes. A three-directional guide device and a four-directional guide device are adopted, and the guide devices consist of steel cylinders containing different numbers of cut openings and handles. Through using different types of guide devices and matching a proper hole distribution mode, the purpose of controlling rock or concrete crushing modes can be achieved. By utilizing the principles that the tensile strength of a brittle material is far lower than compressive strength and concentrated tensile strength easily occurs in the cut opening positions of the cylinders, crushed bodies easily crack in cut opening positions, and the purpose of controlling crack expansion directions is achieved. The size of tensile stress produced by a static crushing agent in the cut opening positions of the cylinders is regulated through changing the cut opening sizes of the cylinders, and a function of regulating hole distances is realized. The purpose of effectively controlling charge quantity is achieved through scale marks on the side walls of the guide devices. The method is suitable for controlling rock or concrete crushing modes and has the characteristics of being simple in structure, being capable of being repeatedly used and the like.
Description
Technical field
Patent of the present invention relates to a kind of for controlling rock or the method for concrete disintegrating pattern.
Background technology
Static breaking agent is a kind of new material utilizing the broken fragility medium of material expansion character, be widely used in breaking concrete and rock fragile materials, static crushing have without shock wave, shockproof, without slungshot, noiselessness, without harmful gas and the advantage such as nuisanceless. Broken purpose is different, needed for the be broken breaking patterns of body also different, the dismounting of temporary concrete structure needs by the body that is broken to be plum blossom-shaped or netted be broken into multiple fritter, in the engineer applied of roof release and raising coal seam permeability, the propagation direction of crackle need to be controlled, to improve crushing efficiency, it is ensured that construction safety. Owing to concrete and rock are anisotropism materials, in shattering process, except the lead crack occurred on boring line, it is also easy to the crackle that other directions occur, breaking patterns is wayward, during site operation, for controlling rock or concrete breaking patterns, general way is by intensive boring, but can be greatly increased workload and construction cost. Considering factors above, for economy, control rock or concrete breaking patterns efficiently, patent of the present invention provides a kind of for controlling rock or the method for concrete disintegrating pattern.
Summary of the invention
Patent of the present invention provides a kind of for controlling rock or the method for concrete disintegrating pattern, by using different types of guider to be equipped with suitable pattern, it is possible to reach to control the purpose of rock or concrete disintegrating pattern. By reaching to control the purpose of direction of crack propagation at bore inner placement guide device. Adjust, by changing the size incision of cylinder, the size of tensile stress that static breaking agent produces at cylinder incision site, reach adjusting hole from effect, thus reducing workload and construction cost. The purpose of effective controlled loading of explosive amount is reached by the graduation mark of guide sidewall. Adopt this guider to be equipped with suitable pattern, rock or concrete breaking patterns can be controlled.
The technical solution realizing above-mentioned purpose is as follows:
Guider is made up of three-dimensional guider and four-way guider. Guider is made up of steel cylinder and the handle containing different incisions quantity. Three-dimensional guider is made up of steel cylinder and the handle containing three otch, and four-way guider is made up of steel cylinder and the handle containing four otch.
Two kinds of guiders are for controlling different breaking patterns. When three-dimensional guider is used for crushing, crackle extends to three cut-out directions, when four-way guider is used for crushing, crackle extends to four cut-out directions, adopt three-dimensional guider, four-way guider and quincunx pattern, it is possible to the body that makes to be broken be that plum blossom-shaped is broken. Adopt four-way guider and criss-cross pattern, it is possible to the body that makes to be broken be latticed crushing. For three-dimensional guider, for filling the static breaking agent slurry being stirred in the middle of cylinder containing three otch, in three otch, the plane included angle of any two otch is 120 °, the tensile strength of fragile material is utilized the principle that tensile stress is concentrated easily to occur far below comprcssive strength and at cylinder incision site, the body that makes to be broken is easy to crack at cylinder incision site, reaches to control the purpose of direction of crack propagation. According to when body size one timing that is broken, the turgor pressure produced in boring is more big, the principle that pitch-row required time broken is more little, changes, by controlling the size of cylinder otch, the size stretching concentration power that aperture position produces, with change broken desired aperture from. Handle extracts boring for being directed to device after having crushed so that it is can reuse. Explosive payload can be efficiently controlled when graduation mark on cylinder side wall is for powder charge, reach to save the purpose of construction cost. Patent of the present invention is applicable to control rock or concrete breaking patterns, has easy to make, simple in construction, the feature such as reusable.
