Abstract
The invention discloses a riverway blasting method and relates to a drilling and charging blasting method. The method comprises the steps that firstly, an operation zone is positioned, a down-the-hole drill and a casing pipe are prepared, and the length of the casing pipe is required to be greater than the water depth of the selected operation zone; secondly, the down-the-hole drill is used for drilling a hole in the operation zone of the step 1; thirdly, the casing pipe in the step 1 is immediately inserted into the drilled hole after the hole is drilled; fourthly, explosive is charged into the casing pipe in the step 3, and a leading wire is reserved; fifthly, the leading wire in the step 4 is ignited to conduct blasting; and sixthly, the blasted zone is cleaned up through an excavating machine. The down-the-hole drill is used for drilling the hole, so that convenience is achieved, and manpower is saved; and a plastic pipe is used for positioning and charging of the explosive, so that the cost is reduced, the operation time is shortened, and the efficiency is improved.
Description
[technical field]
The present invention relates to a kind of borehole charge blasting method, particularly relate to a kind of for the blasting method under urban river water.
[background technology]
Drawing water in river course borehole blasting rock many employings cofferdam both at home and abroad now, it is necessary to then the water draining burst region clear up silt with ditcher, expose rock and implement explosion, such method is loaded down with trivial details, and greatly, efficiency is also low for artificial and energy expenditure；Also there is the method loading explosive at lower water, but owing to being directly load explosive under water, it is easy to soak explosive, and bad location and an ignition, consuming time and success rate is not high.
[summary of the invention]
It is an object of the invention to effectively overcome the deficiency of above-mentioned technology, it is provided that a kind of river course blasting method, the method is simple, speed is fast, cost is low, efficiency is high and can save manpower.
The present invention is achieved through the following technical solutions:
It comprises the following steps:
Step one, positioning operation region, prepare hidden hole drilling and sleeve pipe, and the length of this sleeve pipe is greater than the depth of water of selected operating area；
With described hidden hole drilling boring in step 2, operating area in step one；
Step 3, be drilled hole after immediately the sleeve pipe in step one is inserted in the hole bored；
Filling explosive in step 4, sleeve pipe in step 3, and reserve lead-in wire；
Step 5, the lead-in wire lighted in step 4, carry out explosion；
Step 6, the region excavation machinery after explosion is cleaned out.
Preferably, described sleeve pipe is the plastic tube that can prevent mud from blocking.
Preferably, the hole count that in described step 2, hidden hole drilling bores is determined according to practical situation, and is immediately inserted into described sleeve pipe after being drilled each hole, waits hole to load explosive after all having beaten, and reserves lead-in wire, then carries out unified explosion.
The beneficial effects of the present invention is: it is holed with hidden hole drilling, conveniently save manpower；It, with preventing the plastic tube that mud blocks from carrying out location and the filling of explosive, provides cost savings and the activity duration, also improves efficiency.
[detailed description of the invention]
Below in conjunction with detailed description of the invention, the invention will be further described.
Specific embodiments of the invention are: the present invention is suitable for the river course explosion of phytal zone.First positioning operation region and the hole count to beat on river course, get out plastic tube and the hidden hole drilling machine of explosion, the length of this plastic tube is greater than the depth of water of selected operating area, and this plastic tube can prevent mud from entering inside pipe, thus preventing blocking pipeline, this plastic tube percentage of explosive can reach 100%.The operative employee of specialty drives hidden hole drilling and starts boring, plastic tube is inserted in the hole behind a complete hole by hidden hole drilling every dozen immediately, all beat rear chargehand in hole to begin in plastic tube, add explosive and reserve lead-in wire, until all of hole beat finish bundle and dynamite charge complete after, every plastic tube all exceeds horizontal plane proper alignment, all of lead-in wire is linked together, begin to carry out unified explosion, implement the region after explosion to clean out with excavation machinery again, just complete the demolition duty of operating area, 100% demolition effect can be reached through the practice present invention.
Present invention hidden hole drilling is holed, and conveniently saves manpower；The present invention, with preventing the plastic tube that mud blocks from positioning and loading explosive, provides cost savings and the activity duration, also improves efficiency.It is more than 5 times of old-fashioned method through calculating the speed of the method explosion, cost savings 70%, manually also save half.
Described above is only presently preferred embodiments of the present invention, and above-mentioned specific embodiment is not limitation of the present invention.In the technological thought category of the present invention, it is possible to various deformation and amendment occur, retouching, amendment or the equivalent replacement that all those of ordinary skill in the art make as described above, belong to the scope that the present invention protects.
