Description
Technical field
The utility model relates to a kind of blasting system being applicable to rockmass high slope.
Background technology
Along with the development of science and technology, the continuous quickening of China's pace of construction, various construction project is as water power, railway, highway and mine etc., constantly develop in depth, large-scale high gradient slope continues to bring out, the stability problem of thing followed rockmass high slope also highlights day by day, and the stability of rockmass high slope dynamical problem embodies in many aspects.
In Practical Project rock mass, rock side slope is not many times one piece of entirety, and there is many joints and crack in the middle of it, this is combined by various structural plane and structure, and this also form the difference composition structure of side slope.Common rock mass structure type can be divided into: block structure, mosaic texture, cataclastic texture, layer structure, stratiform cataclastic texture, prose style free from parallelism structure.The intensity of jointed rock mass, distortion and stability mainly affect by structural plane.For the rock mass of different types of structure, the character of its vibrations reaction is also different.Blocky structural rock mass good integrity, the deformation behaviour under dynamic action is close to Homogeneous Elastic Solid, and stability is better.Mosaic texture rock mass may cause avalanche and the falling rocks of local under shock effect, but generally unstable failure can not occur.Rock-mass with cataclastic texture reacts than stronger under shock effect, likely chipping Structure Rock loosen thus cause large-scale avalanche, falling rocks and small-scale slip.By roofing control, under effect of vibration, also may there is large-scale landslide and fluent in Bedded Rocks.
From the shock-effect that slope construction Excavation blasting produces, the important external factor of stability of slope, more and more receives the concern of people as an influence.
Utility model content
The technical problem that the utility model solves is that providing a kind of can significantly stop and reduce the blasting system that be applicable to high slope of explosive charge to the enormous impact that rock mass produces, to solve the landslide of causing in rockmass high slope digging process and fluent problem mentioned in above-mentioned background technology.
To achieve these goals, the technical problem that the utility model solves realizes by the following technical solutions:
Be applicable to the blasting system of high slope, comprise blasting cartridge, the blasting charge, primacord; The length of described blasting cartridge is identical with the degree of depth in big gun hole in high slope, and the top of blasting cartridge is sealed by explosion-proof packed layer; The described blasting charge is divided into the blasting charge at the bottom of hole and the unsettled blasting charge; At the bottom of described hole, the blasting charge is arranged on the bottom of blasting cartridge, and the quantity of the unsettled blasting charge is multiple, be successively set on the blasting charge at the bottom of hole and explosion-proof packed layer sealing between; Described primacord is the blasting charge at the bottom of connecting hole and the unsettled blasting charge successively.
Further, at the bottom of described hole, the height of explosive in blasting cartridge is between 0.9-1.1mm.
Further, the described unsettled blasting charge is emulsion, and the weight of the unsettled blasting charge is 150g.
Further, described explosion-proof packed layer is sealed in the height in blasting cartridge is between 0.9-1.1mm.
beneficial effect
The utility model utilizes the segmentation of the blasting charge to install, form batch (-type) explosion, can significantly stop and cushion the energy of explosive blasting release, thus greatly reduce the impact of blast to surrounding rock body, avoid and a large amount of crack is produced to the rock of big gun hole half periphery, thus the stability of country rock after significantly improving rock mass engineering project Blasting Excavation, economic benefit is huge.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is high slope steel for shot profile.
Detailed description of the invention
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in Figure 1, be applicable to the blasting system of high slope, comprise blasting cartridge 1, the blasting charge, primacord 5; The length of described blasting cartridge 1 is identical with the degree of depth in big gun hole in high slope, and the top of blasting cartridge 1 is sealed by explosion-proof packed layer 4, and the height of explosion-proof packed layer 4 in blasting cartridge 1 is between 0.9-1.1mm; The described blasting charge is divided into the blasting charge 2 at the bottom of hole and the unsettled blasting charge 3; At the bottom of described hole, the blasting charge 2 is arranged on the bottom of blasting cartridge 1, at the bottom of hole, the height of the blasting charge 2 in blasting cartridge 1 is between 0.9-1.1mm, and the unsettled blasting charge 3 is emulsion, and weight is 150g, the quantity of the unsettled blasting charge 3 is multiple, to be successively set at the bottom of hole between the blasting charge 2 and explosion-proof packed layer 4; Described primacord 5 is the blasting charge 2 at the bottom of connecting hole and the unsettled blasting charge 3 successively.
As shown in Figure 2, first in the high slope needing excavation, big gun hole is bored, big gun hole is divided into main quick-fried big gun hole 6, buffering big gun hole 7 and presplitting big gun hole 8, then, degree of depth difference according to big gun hole selects the utility model with big gun hole adaptation, and the present invention is put into big gun hole, and primacord 5 is outside in big gun hole, pull primacord 5 to ignite the utility model, and then the high slope that needs are excavated is separated landing according to design direction.
The utility model is by installing explosive segmentation, and with a primacord, each section of blasting charge is connected, thus form batch (-type) explosion, can significantly stop and cushion the energy of explosive blasting release, thus greatly reduce the impact of blast to surrounding rock body, avoid and a large amount of crack is produced to the rock of big gun hole half periphery, thus the stability of country rock after significantly improving rock mass engineering project Blasting Excavation, economic benefit is huge.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand, the utility model is not restricted to the described embodiments, what describe in above-described embodiment and description just illustrates principle of the present utility model, under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, such as: explosive cartridge suggestion fragility pvc pipe (rainy day construction) or paper web all can, primacord is the blasting charge at the bottom of connecting hole and the unsettled blasting charge successively, after pulling primacord, ignite from the top down or outside in, the concrete time interval considers that Test in Situ characteristic and construction are specifically determined, etc..These changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
