Abstract

A kind of directional blasting demolishment piecemeal oblique initiation networking connection method, explosion building plane will be needed to be divided into some grids by transverse and longitudinal, building width is divided into 2 regions, every 2~3 row column of length direction is divided into a region, first column region in the first row region detonates at first, the first row in the second row region and second column region in the first row region are same hatched example areas, the secondary series in the second row region and the 3rd column region in the first row region are same hatched example areas, Nonel detonator in hole and explosive are fitted into blasthole by area dividing oblique line arrangement principle, and form complete blasting circuit.The present invention is by building plane in transverse direction, vertical partition domain, it is interregional to delay respectively around, so that building blasting process it is hollow it is middle distortion, pull, column, beam and floor flexural deformation, successively sheared, extrude and impact failure and fully disintegrate, blasting vibration and slump vibration can not only be reduced, prevents lower seat and recoil, can more reduce quick-fried rear broken disintegration cost.

Description

A kind of directional blasting demolishment piecemeal oblique initiation networking connection method
Technical field
The invention belongs to building Blasting Demolition Technology field, more particularly to a kind of directional blasting demolishment piecemeal oblique initiation net Road connection method.
Background technology
Current domestic building directional blasting demolishment blasting circuit mainly uses blasting circuit by row, this blasting circuit General principle is exactly that the bearing column or wall of building are destroyed using blasting energy, is formed " the quick-fried discrepancy in elevation ", makes building deviation of gravity center Building load-carrying members scope, so that building overall collapse, collapsing, disintegrating.When delaying between the typically former row rows of the blasting circuit Between it is short, last row delays, and time is slightly long, and some even hinge rows are without explosion.Its advantage is that networking is simple, work progress In to be not easy detonator section in wrongly installed hole other;But have that disintegration effect is poor simultaneously, explosion slump vibration is big, is sat back and waited after easily producing scarce Point.
The content of the invention
Shadow of the Building demolition explosion slump vibration to peripheral facility can be effectively reduced it is an object of the invention to provide a kind of Ring, prevent building recoil from damaging collapse direction back-protective thing, and solve that building disintegration effect is poor, crush the problems such as cost height Directional blasting demolishment piecemeal oblique initiation networking connection method.
The directional blasting demolishment piecemeal oblique initiation networking connection method of the present invention, comprises the following steps:Explosion building will be needed Room plane is divided into some grids by transverse and longitudinal, and building width is divided into 2 regions, and every 2~3 row column of length direction is divided into one Region, two row parallel zones are formed, first column region in the first row region detonates at first, and the extension time is 0.5s, the second row area The first row in domain and second column region in the first row region are same hatched example areas, and the extension time is 1.0s, the second row region Secondary series and the 3rd column region in the first row region are same hatched example areas, and the extension time is 1.5s, and piecemeal is carried out by this principle Oblique line subregion, Nonel detonator in hole and explosive are fitted into blasthole by area dividing oblique line arrangement principle;By detonator in hole Every 10 ~ 15 of detonator wire is banded together and connected with the outer wink hair Nonel detonator of 2 hair engaging aperture;Detonator main line main line is laid Burst region is being needed, is forming two-wire closed-loop path;Nonel detonator will be sent out wink outside all holes and be connected to a master with four-way respectively Detonator connection is provided with main line, between the four-way of the outer wink hair Nonel detonator connection of two root holes to communicate;Need every floor layer of explosion It is attached as stated above, each floor gap is attached with interlayer Millisecond Nonel Tube Detonator after connection, is entered from the bottom to top Row propagation of explosion, each floor gap need 3 ~ 4 intercommunication propagation of explosion circuits;Detonation main line is connected with bottom explosion backbone, detonation main line is drawn To detonation station complete blasting circuit is connected to form with initiator.
The present invention directional blasting demolishment piecemeal oblique initiation networking connection method general principle be:By building plane in horizontal stroke To, be longitudinally divided into some regions, the interregional 0.5s that delays respectively around so that the hollow middle distortion of building blasting process, drawing Pull, column, beam and floor flexural deformation, successively sheared, extrude and impact failure and fully disintegrate.By " time difference " and " discrepancy in elevation " makes building point disintegrate very abundant across contacting to earth successively, can not only reduce blasting vibration and slump vibration, prevent lower seat And recoil, it can more reduce quick-fried rear broken disintegration cost.
