Description
Technical field
The utility model belongs to engineering explosion technical field, is specifically related to a kind of dustproof device for reducing dust using in demolition blasting.
Background technology
Along with the development of China's urban construction, a large amount of waste and old constructions of structures face dismounting.First the method for dismounting of construction of structures is demolition blasting, and demolition blasting is more and more higher to the requirement of environmental protection, and especially the harm of blasting dust more and more causes the concern of the whole society.The dust speed that City Building demolition blasting produces is fast, sudden strong, particle is tiny, long in the time of outdoor conditions low suspension, pollution range is large and restive.Not only affect bursting work personnel's health, contaminated environment and equipment, affect resident's normal work and life simultaneously, therefore when construction of structures demolition blasting, must take dustproof measurements for reduction.Traditional dustproof measurements for reduction, generally to carry out the dustproof depositing dust of water smoke with blast water bag, on explosion object, hang the water bag that explosive and water are housed, utilize explosive charge energy to make water fogging, form countless droplet disperses in air, drop and airborne dust finally settle down by contact forms such as collision, cementing, cohesions.The design of water bag is key technology in the dustproof depositing dust technique of water smoke, the directly effect of the dustproof depositing dust of impact.Traditional water bag generally adopts common plastics bag, has the following disadvantages.
1) strength of materials is not enough, is easily scratched, punctures, and causes infiltration to be leaked.
2) water bag opening is excessive, water-filling, powder charge, is all unfavorable for operation while hanging.
3) after water-filling, water bag is spherical, while hanging, can not cover blasting cut was completely.And the water smoke forming is inhomogeneous, dustproof dust-laying effect is not ideal enough.
4) explosive packing in water bag directly contacts with water with detonator, and the possibility of miss-firing is larger.
Summary of the invention
The purpose of this utility model is the defect existing in order to overcome existing dustproof depositing dust water bag, and a kind of device for reducing dust using in demolition blasting is provided, can safety, dust economic, that effectively produce during controlled blasting.
Technical solution of the present utility model is: a kind of device for reducing dust using in demolition blasting, for making in advance shaped device, the cutting part at demolition blasting during use hangs.
Device for reducing dust described in the utility model, be the water bag being formed by water cell, adopt and have the plastic material of national standard to make, by the standard water cell formation of 50cm * 30cm * 10cm, between each water cell, adopt and be flexible coupling, can select as required water cell number.Each water cell top is equipped with circular hole, and galvanized wire, through circular hole, is wound around water bag or hang on the blasting cut was place of blasting body.Edge in each water cell, circular hole below is established and is equipped with buckle, for fixing detonator.In each water cell, all tool is provided with powder charge chamber, and the end in powder charge chamber is provided with unidirectional water inlet, and water pipe inserts unidirectional water inlet to water cell water-filling, and after water-filling, powder charge chamber can be used as the filling point of detonator, explosive or primacord.
The utility model is installed by following construction process: 1, select as required water cell number; 2, depositing dust water bag is hung on to blasting cut was place; 3, by unidirectional water inlet water-filling; 4, in powder charge chamber, install explosive and detonator, explosive or primacord, detonator is fixed on buckle.
The beneficial effects of the utility model are: 1,, compared to traditional water bag, this water bag is convenient, flexible, conveniently hang, and easy construction is not subject to the restriction of execution conditions, do not affect other normal constructions; 2, design parameter has standard a nd norm to follow, and is easy to quantize to calculate and promote, economic and practical; 3, be that unit bodies ponding can play larger area coverage, operating efficiency is high; 4, the water medicine separation accident of can not miss-firing, promotes the effect of dustproof depositing dust greatly.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
The device for reducing dust using in demolition blasting, is the water bag consisting of water cell 3, between each water cell 3, adopts and is flexible coupling 6; Water cell 3 tops are provided with circular hole 1; Edge in water cell 3, circular hole 1 below is provided with buckle 2; In the interior powder charge chamber 4 that arranges of water cell 3; The end in powder charge chamber 4 is established unidirectional water inlet 5.
Making and the installation steps of depositing dust water bag are as follows.
1, rapidoprint: water bag material adopts standard GB/T/T4456-2008 to select PE-MD processing, and the thickness of water bag is not less than 0.1mm, the flaws such as the bubble that do not have, perforation.
2, galvanized wire 11 reference standard YBT5294-2009, tensile strength is not less than 400Mp, and rate elongation is not less than 12%, and galvanized wire 11 should be selected 10-14 galvanized wire, wherein with No. 12 galvanized iron the bests.
3, according to actual conditions needs, select after suitable water bag number, from being flexible coupling between water bag, 6 cut off.
4, galvanized wire 11 is passed to the circular hole 1 of water cell 3 tops, water bag is wound around or hang on to the blasting cut was place of blasting body.
5, water pipe is inserted to the unidirectional water inlet 5 of water cell 3, after water-filling 7, extract.
6, pack detonator 8, explosive or primacord 9 into powder charge chamber 4, finally detonator 10 is fixed on buckle 2.
