Description
Technical field
The present invention relates to a kind of device and blasting methods for exempting to punch demolition blasting tubular steel column, belong to explosion field.
Background technique
It in China, faces a large amount of steel construction and needs to remove, some is tubular steel column structure building, using artificial
It removes, large labor intensity, and risk is high, using mechanical removal, removes low efficiency.In tubular steel column structure building,
Can not by punching explosion, can only dobie, a big chunk energy is dispersed into air, and demolition effect is poor.It is built in tubular
Concrete explosion is only applicable to the biggish cylindrical steel structure of cross-sectional area, and construction site casting concrete and curing time are long, beats
Hole operation destroys casting concrete structure, and inside concrete damage is unknowable, influences to weld under explosive payload judgement and complex environment
It connects and to pour operation difficulty big.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the present invention provides one kind and exempts to punch demolition blasting cylinder
The device of shape steel column and blasting method pour into granule medium in tubular Gao Zhuzhong by being put into pack in tubular steel column, so that
Pack explosion in steel column, significantly increases demolition effect, and blasting efficiency is high.
Technical solution: in order to solve the above technical problems, the device for exempting to punch demolition blasting tubular steel column of the invention, including
Granule medium in tubular steel column is placed with pack, the side of connecting tube in connecting tube inserted with connecting tube in granule medium
Wall is equipped with opening, and the top of connecting tube is equipped with gas cell, and gas cell is equipped with gas tube, concrete has been poured on gas cell
Block, conduit pass through concrete block and gas cell, and the Nonel detonator of pack is drawn by opening and conduit.
Preferably, the connecting tube is pvc pipe.
Preferably, the tubular steel column is radially equipped with impermeable cutting seam.
Preferably, the tubular steel column is radially equipped with penetrating cutting seam, cutting seam is sealed by sealant.
The utility model has the advantages that the device for exempting to punch demolition blasting tubular steel column of the invention, cuts with notch, in notch on steel column
It is inside put into connecting tube, pack is put into connecting tube, granule medium is injected, is put into gas cell, the mixed of thin layer is perfused on gas cell
Granule medium, is sealed in steel column, igniting primer, using the Incoercibility of granule medium, greatly by solidifying soil by concrete
Improve explosion extent of the destruction, can guarantee demolition effect.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
The present invention will be further explained with reference to the accompanying drawing.
As shown in Figure 1, the device for exempting to punch demolition blasting tubular steel column of the invention, including being located in tubular steel column 1
Granule medium, inserted with connecting tube 5 in granule medium, the connecting tube 5 is preferably pvc pipe, is placed with pack 4 in connecting tube 5,
Pack 4 is fixed in connecting tube 5 by stemming, and the side wall of connecting tube 5 is equipped with opening, and the top of connecting tube 5 is equipped with gas cell 3,
Gas cell 3 is equipped with gas tube, and concrete block 2 has been poured on gas cell 3, and conduit 8 passes through concrete block 2 and gas cell 3, medicine
The Nonel detonator of packet 4 is drawn by opening and conduit 8.The tubular steel column 1 is radially equipped with impermeable cutting and stitches, described
Tubular steel column 1 can also radially be equipped with penetrating cutting and stitch, and cutting seam is sealed by sealant.
The blasting method for exempting to punch the device of demolition blasting tubular steel column 1 of the invention, comprising the following steps:
(1) notch 7 is cut on tubular steel column 1 to be blasted, 7 height of notch and size are according to tubular steel column to be blasted
1 size determines；
(2) pack 4 is put into connecting tube 5, pack 4 is fixed by stemming, and pack 4 is connect with Nonel detonator, is led quick-fried
Pipe detonator is drawn from opening；
(3) connecting tube 5 is inserted into steel column 1 from from notch 7, filling sand medium, sand medium and connecting tube into steel column 1
5 height are consistent, and Nonel detonator passes through conduit 8, are introduced at notch 7；
(4) it is inflated to gas cell 3, so that gas cell 3 squeezes 1 inner wall of steel column；
(4) cement mortar is poured into steel column 1, is formed concrete block 2, is mixed with fast agglomerating agent in cement mortar；
(5) it after maintenance, detonates to pack 44, completes the explosion to steel column 1.
In the present invention, the explosive that pack uses is easier to obtain for 2# rock emulsion explosive, compared with control explosive, between explosive
Every be placed in connecting tube, explosive utilization rate is high, saves explosive cost, and lesser dose reaches target, and optional
A variety of charging means and interval mode are selected, explosive acting ability is more made full use of not generate slungshot in blast process.
