Description
Technical field
The present invention relates to blasting technique field, particularly relate to a kind of detonator four-way and connect propagation of explosion method of operating.
Background technology
Nonel tube network system with its construction safety, cost is low, connection is simple, in mine blasting and urban demolition blasting, be used widely.
At present, Nonel tube network has two kinds of fundamental types: the one, and multistage pencil relay-type connects, and also claims a bunch networking road, and its connection speed is fast, propagation of explosion detonator consumption is large, but potential safety hazard is many; The 2nd, reflection four-way connects networking, uses hardly propagation of explosion detonator, construction safety, but contact is many, and these two types have different connection forms separately, and the complexity that multi-form its networking connects and the system reliability of detonating often has very large difference.
Summary of the invention
In order to overcome defect of the prior art, the object of this invention is to provide a kind of detonator four-way and connect propagation of explosion method of operating.
On the pros and cons of the various Nonel tube network methods of attachment of having analyzed and researched and the basis of a large amount of engineering practices, employing bunchy connection in the first stage has been proposed, the two little grid complex loop of the main line propagation of explosions of four-way, multiple spot electric cap excitation technique, greatly shortened the connect hours at four-way networking, guaranteed that again networking has the higher reliability of detonating.
The present invention is achieved by the following technical solutions:
Detonator four-way connects a propagation of explosion method of operating, at least comprises the following steps:
Step 101: packing explosive is become owner of to blast hole, and the described blasting charge is connected with a detonator; Get two detonators and be connected with leading booster, at two detonators and leading booster junction, four-way connector is installed;
Step 102: described four-way connector, leading booster, a detonator are sealed into one with adhesive tape;
Step 103: will dominate booster and be connected with apparatus to cause bursting, and according to above-mentioned steps 101-102, be connected to a blasting network system by packing the blastings charge all in described main blast hole into through leading booster, a detonator.
Further, described four-way connector can lead to fitting as three-way connector or two, easy to use.
Four-way connector of the present invention just can pass to a detonator the shunting of the detonation wave of leading booster of the prior art without propagation of explosion detonator.
Compared with prior art, the superior effect that a kind of detonator four-way of the present invention connects propagation of explosion method of operating is: after adopting described four-way connector, cancelled propagation of explosion detonator, reduced cost, improved operational security, and eliminated in prior art the disconnected quick-fried possibility of propagation of explosion detonator cumulative, reduced blasting vibration ill-effect, improved blasting network connection speed, guaranteed that blasting network connects and propagation of explosion security.
Accompanying drawing explanation
Fig. 1 is for adopting described a kind of detonator four-way to connect the leading booster of propagation of explosion method of operating, a detonator connection diagram;
Fig. 2 is four-way connector profile of the present invention.
Accompanying drawing sign is as follows:
1-dominates booster, 2-props up detonator, the 3-blasting charge, 4-four-way connector.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the invention is described in further detail.
As shown in accompanying drawing 1-2, a kind of detonator four-way connects propagation of explosion method of operating, comprises the following steps:
Step 101: pack the blasting charge 3 into main blast hole (not shown), the described blasting charge 3 is connected with a detonator 2; Get two detonators 2 and be connected with leading booster 1, in two detonators 2 and leading booster 1 junction, four-way connector 4 is installed;
Step 102: described four-way connector 4, leading booster 1, a detonator 2 are sealed into one with adhesive tape (not shown);
Step 103: will dominate booster 1 and be connected with apparatus to cause bursting (not shown), and according to above-mentioned steps 101-102, be connected to a blasting network system by packing the blasting charge all in described main blast hole 3 into through leading booster 1, a detonator 2.
When two detonators 2 are specifically connected with leading booster 1, to dominate 180 ° of booster 1 doublings, adopt Work tool that leading booster 1 is divided into two, the leading booster cutting off is connected with two detonators 2, two leading boosters 1 and two detonators 2 are inserted in described four-way connector 4.
At present, each propagation of explosion detonator (5m buttock line) price is: 6.5 yuan; Each four-way connector price is 0.3-0.5 unit, and detonator price is 0.5 yuan/m.
Adopt traditional detonating primer detonator to connect, each node needs at least one Nonel detonator, and price is 6.5 yuan; Adopt detonator four-way interconnection technique, each node is used a four-way, uses 5m detonator, and price is 2.8-3 unit, therefore cost-saved more than 50%.
A kind of detonator four-way of the present invention connects propagation of explosion method of operating and has been successfully applied to diversion tunnel import and export slope blasting project in rainwater in puddles Milky Way reservoir extension project.Because duration task is tight, difficulty is large, particularly the maximum length of slope of import reaches 378m, and near import 70m, there is former rainwater in puddles Milky Way reservoir dam and power plant building, have relatively high expectations (explosion design is controlled according to V=0.7cm/s) that this Blasting Vibration Velocity is controlled, therefore must adopt effective control measure, under this background, adopted detonator four-way to connect propagation of explosion technology, reaching 4-5 hole is an initiating unit, with this, controls explosive quantity in a sound, reaches the effect of controlled blasting vibration limits effect.
Leading booster of the present invention, a detonator, the blasting charge, four-way connector, adhesive tape are prior art.
The present invention is not limited to above-mentioned embodiment, and in the situation that not deviating from flesh and blood of the present invention, any distortion it may occur to persons skilled in the art that, improvement, replacement all fall into scope of the present invention.
