Description
Technical Field
The utility model belongs to the technical field of the engineering blasting technique and specifically relates to a sticky tape that is used for explosive cartridge ligature of rock mass blasting construction that is used for fields such as mine, water and electricity, traffic.
Background
In rock blasting construction, a drilling blasting construction method is generally adopted, and two charging modes, namely a coupling charging mode and a non-coupling charging mode, are adopted. The coupled charging means a charging form that the diameter of the cartridge is equal to that of the blast hole, after rock powder or coal dust in the blast hole is removed, the cartridge is slightly pushed into the cartridge by a wooden or bamboo stick to complete charging, so that the cartridges in the blast hole are tightly connected. The uncoupled charging is a charging form that the diameter of the blast hole is larger than that of the cartridge, and can weaken the initial pressure peak value acting on the blast hole and prolong the acting time of detonation gas products so as to improve the blasting effect, such as reducing the thickness of a rock crushing ring, being beneficial to contour surface forming and the like; the uncoupled charging structure is widely applied to presplitting blasting and smooth blasting in hydropower, traffic and mine engineering. In the charging of blast holes with large non-coupling coefficients such as contour blasting, in order to ensure that the shape and the connection effect of the charged explosive cartridge in the blast hole are not damaged, the explosive cartridge and the detonating cord are generally bound on a long bamboo sheet or a wood sheet in engineering, and are slowly pushed into the blast hole to be blocked, so that the charging is completed.
When the explosive is not coupled to be charged and blasted, the binding of the explosive cartridge is an important link in the charging process, and the charging quality is directly influenced, so that the quality of the blasting effect is influenced. If the binding is not firm, the explosive cartridge and the detonating cord are easy to separate, and certain potential safety hazards exist; two sections of spaced explosive rolls of the axial air spacing section are connected to form local continuous charging, so that the pressure distribution of blast holes is uneven during blasting, and the quality forming effect of the profile surface is poor. In the prior art, an electrical adhesive tape is used for binding explosive cartridges, and in the construction operation process, the steps of finding the end of the adhesive tape, tearing and cutting the adhesive tape, binding the explosive cartridges and the like need to be repeated continuously, so that the operation is complicated, and the construction efficiency is seriously influenced; meanwhile, the number of turns of the adhesive tape wound on the single section of explosive cartridge is not controlled, the adhesive tape is wasted due to the fact that the adhesive tape is wound repeatedly for the purpose of reliable binding, and the relation between the binding quality and the cost is difficult to coordinate by construction personnel in the operation process.
The Chinese patent publication No. CN 209024447U discloses an adhesive tape comprising an adhesive layer and a release layer covering the adhesive surface of the adhesive layer, wherein the release layer is divided into at least two areas by a tearing line thereon; through the tear line, can be in turn with the peel off layer in different regions follow peel off on pasting the layer to pass through in turn paste the position of pasting corresponding to the peel off layer in different regions on pasting the layer and paste, can realize the used repeatedly to same sticky tape. The shape of the adhesive tape is zigzag, I-shaped and the like, and the complicated shape design is not suitable for being used in the explosive binding process; in addition, in the using process, the tearing line needs to be found and torn when the adhesive tape is used for the second time, the operation difficulty is increased, and the binding efficiency is reduced.
The Chinese patent publication No. CN 209276429U discloses an elastic composite adhesive tape, which comprises an adhesive tape supporting sleeve, a sliding groove, a sliding block and a label needle. The outer layer of the adhesive tape main body is provided with a protective film, the inner layer of the protective film is provided with a protective layer, the inner layer of the protective layer is provided with a composite material layer, and the inner layer of the composite material layer is provided with an adhesive layer, so that the adhesive tape main body has good flame retardance, toughness and corrosion resistance; the slider and the tag pin are used to find the tip. However, the adhesive tape is not economical, the taking length of the adhesive tape is not easy to control, and the adhesive tape is not suitable for large-scale explosive binding work.
At present, aiming at the problems of complex and irregular operation, waste of adhesive tapes and the like in the binding process, a new solution and a binding technology are not provided, and the problems in the current practical operation are not effectively solved.
