Amount, and realize and Each part is progressively uniformly unloaded.
3 network reliabilities
3.1 reliability factors are analyzed
It is normal to blasthole more than 5,000 using delay-more Hole-hole short-delay blasting schemes outside hole in bridge demolition demolishing process
Detonation, its blasting network are extremely complex.To avoid blasting network from destroying, to rationally design and optimize network, ensure blasting network
The reliability of propagation of explosion.The non-artificial factor of destruction at demolition blasting network mainly has following three aspects；
（1）Blasting flyrock cut-out network connection
Since the uncertain factor of explosion produces a large amount of blasting flyrocks, network connection around may be damaged,
There is phenomenon of miss-firing.
15 sections of detonators are used in hole, delay duration is 880 ± 60 ms；3 sections of detonators of hole external application, delay duration are 50 ± 10
Ms, minimum aperture is away from for 0.4 m, about 1950 m/s of detonator velocity of explosion.Ith, the most short safety of I ' area, first group of blasthole detonation is prolonged
When about 820 ms of the time, every thereafter group of interval explosion most short safety delay time is 40 ms.Therefore, analysis detonation net is calculated
Pass pops begin to propagation of explosion to last 1 blasthole hole in detonator the most long propagation of explosion time more than the delay time in the 1st blasthole hole,
First quick-fried blasthole slungshot may damage rear quick-fried blasting circuit, must carry out corresponding security protection, just can guarantee that the peace at network
Entirely.
（2）Blasting cap detonation product and metal fragment cut-out propagation of explosion network
After blasting cap detonation, explosion product and metal fragmentation are concentrated mainly on immediately below detonator both sides and afterbody.Wherein metal
Fragment disperses with extremely strong directionality, is in spherical diffusion centered at the high explosive of detonator bottom, the initial velocity of metal fragment
Degree is gradually reduced in air borne because being increased over time by drag effect.But the degree of metal fragment is big, and the propagation time is far small
In the time being delayed outside detonator propagation of explosion and hole, fragmentation and metal jet that Nonel detonator explosion produces are easily to neighbouring detonator
Have an impact, cause network propagation of explosion to interrupt or destroy surrounding network.
（3）Arch rib, which crushes to fall, pounds suspension road
About 107 m of arch arc length, vault fall with larger huge away from 0~13 m of bridge floor, blasting broken stone after explosion
Impact force may destroy other networks of bridge floor.
It is most short along vertical bridge floor direction fall time since blasting broken stone disperses with non-directiveness, and cause arch rib
The main cause that lower section network is destroyed.Bridge arch is the IV, the IV ' area, most short safety delay time=820+40 × 4 of its blasthole propagation of explosion=
980 ms, about propagation of explosion can calculate first group of blasthole about at ribbed arch 3/5 according to the safe delay time and start to the 16th beam blasthole
It is quick-fried, most short=70 ms or so.Therefore floorings network about 21~30 m distances of propagation of explosion, can not finish floorings network propagation of explosion,
The network of bridge floor under arch rib may be caused to destroy.
Based on above-mentioned network destructive factor, quantitative calculating is carried out to the propagation of explosion of blasting network reliability and has been analyzed, explosion
It is the principal element for causing demolition blasting network reliability that slungshot, detonator metal fragment cut-out network and dismounting thing, which pound suspension road,.
In order to realize that more blastholes and all detonators are effectively detonated, avoid because occurring miss-firing during propagation of explosion, interrupt and the accident such as blind big gun, or even lead
Blast action direction is caused to change so as to produce blasting damage, improvement demolition effect is good, improves blasting quality, should pay much attention to network
Safety, and the security protection of network reliability is carried out, ensure the propagation of explosion of networking security.
3.2 safeguard procedures
Extensive demolition blasting, requires height, using the detonation for the porous Millisecond Controlled Blasting that be delayed outside hole to blasting technique
Mode, blasting circuit detonation propagation reliability of nonel tube are related to the success or failure of whole blasting engineering, and the importance of networking security protection is well imagined.
, as breach, technological innovation will be carried out at blasting network weakest link, network reliability is improved to optimize network design.
（1）Wire jumper technology
Wire jumper technology refers to the factor that may be destroyed by analyzing network, accurate to calculate network delay time, from it
A network line is connect between his area or group in the position of identical burst time point, unicom between Shi Liang areas or group, realizes that network is stablized
Propagation of explosion.
1）Section wire jumper
Ith, the time-delayed safe time in I ' area is about 820 ms, and network can stablize 13 beam of propagation of explosion about 15~22m；IIIth, III ' area
Delay time is about 760 ms, about about 15~21 m of 12 beam of propagation of explosion under the influence of area I, I '；Ith area and IIIth area part to be removed
Network propagation of explosion can finish within the effective delay time, will not be damaged by factors such as blasting flyrocks.
IIth, II ' is big with the quantities at IV, IV ' place to be torn open of area, and the number of the boring hole is more, density is big and propagation of explosion distance, Yi Shouxian
The influence of quick-fried blasthole and destroy network, the safety prevention measure at network must be taken.Ith, I ' be located at III, III ' area it is right under floorings
IIth, smaller can be neglected is destroyed at network on II ' and IV, IV ' bridge floor.Section wire jumper technology is used in II, II ' and IV, IV ' area.Through
Networking security calculates and analyzes the 13rd beam in first group of II the 3rd Zu He of area of Ke, IVth areas, in IVth areas of the 13rd Shu He of the 7th group of IIth area
Wire jumper between second group of the 16th beam, is hereafter spaced 6 beam wire jumpers once, as shown in Fig. 4 a；IIth, the 15th beam in every group of II ' area and
Wire jumper after 25th beam, is hereafter spaced 10 beam wire jumpers once, as shown in Fig. 4 b.
2）Wire jumper between group
IIth, II ' area's the number of the boring hole is more, and section wire jumper can not ensure the networking security in the region, so II, II ' area is at the same time
Using wire jumper technology between group：Wire jumper and the 2nd group of the 12nd beam and the 5th group between 1st group of the 13rd beam and the 4th group of the 10th beam
9th interfascicular wire jumper, is hereafter spaced 6 beam wire jumpers once.It is interconnected, detonates from two to intermediate symmetry, such as between each group network
Shown in Fig. 5.
（2）The gland or bedding of flexible material
Since floorings blasthole is intensive, during propagation of explosion detonator easily because front-seat blasthole is first quick-fried, blasting network be easier to by
Metal fragment cut-out or slungshot are pounded disconnected.Therefore, often occur network propagation of explosion to interrupt in engineering explosion and cause local blind big gun or refuse
Quick-fried phenomenon, can cause blast action direction to change initiation accident when serious.
This engineering uses the short-delay blasting that is delayed outside hole, uses flexible material gland outside hole on delay detonator before explosion,
Influence of the fragment to disperse in blasting process to network can effectively be weakened.In view of this quantities is big and cost, gathers materials on the spot and adopt
Covered and be pressed on detonator with sandbag, also there is certain protective action to network.With flexible material bedding about 3/5 under arch rib at bridge floor
On the network of plate, to slow down blasting network because of arch rib blasting flyrock or influence of the metal fragment to blasting network of dispersing.
3.3 Engineering application analysis
This demolition blasting engineering uses the form of more blasthole small pit goafs, and be delayed network feature outside combined hole, utilizes wire jumper skill
Art designs blasting network and blasting scheme, its Bridge cloth hole is up to more than 5,000.In whole blasting engineering implementation process, substantially by
