Description
Technical field
The invention belongs to structure demolition demolition technique field, be specifically related to the structure demolition dismounting and use explosion equipment.
Background technology
City Building control BLASTING TECHNOLOGY FOR DEMOLITION is the important means of removing high-lager building and structures at present; The environment more complicated of City Building and structures control demolition blasting; General many places are in the business district, and personnel and other building are intensive, and are strict to safety and environmental protection requirement.The safety problem that City Building and structures demolition blasting relate to mainly contains the intensity of controlled blasting collapse direction and collapse scope, controlled blasting stone fling distance and blasting vibration effect.Relating to environmental protection aspect problem mainly is broken influence and the harm that environment is produced of controlled blasting noise and explosion dust.Technology such as safety hazard such as demolition blasting noise, slungshot and vibration can adopt that energy differential, orientation are caved in, delaying blasting and reinforcement protection are effectively controlled.But the dust that City Building and structures demolition blasting are produced is because speed is fast; Sudden strong, particle is tiny, when especially in densely populated urban district, carrying out demolition blasting, follows report and the billowing dust that comes fills the air everywhere; Both contaminated environment was detrimental to health again.At present, the technology that lacks effective, practical control demolition blasting dust.
The patent No. is 200710123067.4 to disclose a kind of building blasting integrated dust-removing method, and its method is before explosion, treats the explosion building with hygroscopicity dust suppressant solution-treated earlier, with the moisture content of quick-fried construction materials such as maintenance and increase; In the explosion scope, make foam then as far as possible, make and treat that the explosion building is surrounded by foam; Also in explosion, in the space of explosion, make active water smoke.Its shortcoming is, more than the method that combines through physics and chemical means, though the demolition blasting dust pollution is effectively controlled, complex process, cost is high.
Summary of the invention
In order to solve the difficult problem that depositing dust is removed in structure demolition, and overcome complex process in the prior art, defect of high cost.The present invention provides a kind of with low cost, production and structure demolition easy to use to remove with blast depositing dust water bag.
Concrete technical scheme is following:
Structure demolition is removed with blast depositing dust water bag and is made up of slurries, destructor and isolated blast water bottle; The raw material of wherein said slurries and weight are: water 96～98kg, binding dust adsorbent 2～4kg;
The raw material of said binding dust adsorbent and weight are: cohesive soil 1.0～2.2kg, binding agent 0.3～0.5kg, aliphatic alcohol polyethenoxy sodium sulphate 0.3～0.5kg, salt 0.4～0.8kg;
Said blast depositing dust water bag prepares according to the following steps:
The first step mixes cohesive soil, binding agent, aliphatic alcohol polyethenoxy sodium sulphate and salt by above-mentioned prescription and to obtain the binding dust adsorbent;
Second step added the binding dust adsorbent in the entry by prescription, and stirring obtains slurries;
In the 3rd step, in the waterproof explosive volume, insert a detonator and obtain destructor;
The 4th step, slurries 50～80kg is poured in the isolated blast water bottle, put into destructor at the center of isolated blast water bottle, promptly make structure demolition and remove with blast depositing dust water bag.
Said cohesive soil is a kind of in yellow soil, the bentonite or both mixtures.
Said binding agent is a kind of in Sodium Polyacrylate, carboxymethyl cellulose, the sodium carboxymethylcellulose.
Said destructor is that a detonator and 75～100g waterproof explosive volume constitute.
Said isolated blast water bottle is the mine explosion-suppression water bag.
Basic principle of the present invention is:
Insoluble component cohesive soil in the binding dust adsorbent and binding agent are dispersed in the water and form the well-mixed slurries of solid-liquid, and the shock wave that when explosive charge, produces forms angry body of blast and slurries gas-liquid-solidly fully to mix, at this moment; Slurries and detonation gas have higher kinetic energy, shed skyborne low-pressure area after the mixing and have caused energy surplus, according to thermodynamic principles; Superfluous energy simultaneously owing to the existence of the strong aliphatic alcohol polyethenoxy sodium sulphate of foamability, has reduced the surface tension of gas-liquid-solid three-phase just to the acting of three-phase mixed liquor; Because the existence of cohesive soil and binding agent; Improved foam surface film strength and toughness,, improved the wettability of foam surface owing to the existence of salt; Therefore, finally formed the fine and smooth three-phase polyhedron foam colony of a large amount of even compacts.
This have more by force adsorb, the polyhedron foam of bonding, wettability aloft fills the air; After will bumping, adsorb with a large amount of dust that the structure demolition dismounting is produced; Dust is attached to the surface of foam colony; Foams increase and fall on the quick-fried heap of explosion building because of catching behind the dust weight, and then have prevented that effectively structure demolition from removing a large amount of dust of being produced aloft with wind drift, have reached the purpose of depositing dust.
The present invention has following characteristics:
1) contains stronger cohesive soil of toughness and binding agent in the three-phase polyhedron foam colony; These stickums are parts of three-phase froth facial mask; But the long period keeps the stability of foam; Even foam is broken, the cohesive soil with certain viscosity and binding agent be the explosion dust that produced of bond buildings dismounting more equably still, aloft drifts about thereby prevent and treat dust effectively;
2) contain in the binding dust adsorbent the stronger aliphatic alcohol polyethenoxy sodium sulphate of foamability, reduced the surface tension of three-phase froth.Simultaneously, salt has stronger moisture absorption and wettability, thereby has improved the stability and the wetability of three-phase froth skin covering of the surface, and the capture ability of structure demolition being removed dust is strong;
3) the mine explosion-suppression water bag of blast depositing dust water bag employing prevents the isolated blast water bottle that gas explosion is used for the colliery underworkings; This water bag intensity is big, and the amount of being filled with water is many, and (50～80kg), the three-phase froth that blast is produced is scattered the big (diameter degree＞3.5m of volume; The diffusion height＞3m); Longer duration (duration＞160ms), it is wide to catch the dust scope, and the time is long.
The present invention compares with the active water smoke that existing structure blast water bag produces, and its remarkable advantage is:
1) in the slurries of building blast water bag, contains the binding dust adsorbent and have functions such as viscosity, foaming, moisture absorption; The a large amount of detonation gases that produce through explosive charge form the three-phase froth that volume significantly increases fast with slurries; And remove dust generation effective collision, absorption, the bonding that produces with structure demolition aloft, and then stop the dust drift.Simultaneously, the dust that ground is up drifted about also has binding dust covering effect;
2) contain cohesive soil and binding agent in the three-phase froth with certain viscosity; These stickums are parts of three-phase froth facial mask; But the long period keeps the stability of foam, even foam is broken, binding agent and cohesive soil with certain viscosity still can adsorb the bonding dust more equably;
3) the isolated blast water bottle intensity that adopts of blast depositing dust water bag is big, and the amount of being filled with water is many, and explosive charge is big, and it is big that the three-phase froth that blast is produced is scattered volume, and it is wide to catch the dust scope, and the time is long;
4) manufacturing approach is easy, and is reliable, safety, and cost is low;
Structure demolition provided by the invention is removed with the requirement of blast depositing dust water bag adaptable across City Building demolition blasting dust explosion water bag depositing dust.
