Description

Technical Field

[0001] The utility model relates to the technical field of blasting and breaking rocks, in particular to a novel integrated blast hole plugging device. Background Art

[0002] At present, in railway tunnel excavation projects, most of them adopt the drilling and blasting method. Usually, drilling machinery and equipment are used to drill blastholes on the face according to the design requirements, and then explosives are loaded in the blastholes. Finally, the explosives are detonated to blast out the rock mass to achieve the purpose of face blasting excavation. During the construction process of the drilling and blasting method, the actual effect of blasting is affected by many factors. Among them, the influence of the choice of blasthole blocking method on the blasting effect of the drilling and blasting method cannot be ignored. At present, the main method used for blasting rock breaking blasthole blocking is to use foam mud or foam mud plus water bag blocking. This blocking method is simple to operate and low in cost, but it still has many shortcomings. For example, during the water bag filling process, it is very easy to be scratched in the hole. When using foam mud for blocking, the foam mud does not have good adhesion with the hole wall, and a good blocking effect cannot be achieved, resulting in different ways and degrees of rock mass fragmentation. Whether the blasthole is quickly and reliably blocked is crucial for the safe and efficient construction of the drilling and blasting method. Therefore, a new integrated blasthole blocking device is needed. Summary of the invention

[0003] In order to improve the utilization rate of explosion energy and overcome the problems of water bags being easily damaged during the filling process, poor adhesion between the foam mud and the hole wall, and poor plugging effect.

[0004] The utility model adopts the following technical solutions:

[0005] A novel integrated blast hole plugging device comprises a sealing plug, a sealing body and a water bag, and is characterized in that: the sealing plug is a truncated cone, a water injection port is arranged in the middle, the lower part is fixedly connected with the sealing body, the sealing body is a solid cylinder, adhesive bags A and adhesive bags B are evenly distributed on the outside, a water bag is connected to the bottom of the sealing body, and four protective strips are arranged around the outer periphery of the water bag.

[0006] Preferably, the sealing plug is in a truncated cone shape, with a water injection port provided in the middle, and the water injection port penetrates the sealing plug and the sealing body to the water bag.

[0007] Preferably, the lower part of the sealing plug is fixedly connected to the sealing body, and the two are integrated and made of the same material, both of which are polyvinyl chloride.

[0008] Preferably, the plugging body is a solid cylinder, with adhesive bags A and adhesive bags B evenly distributed on the outside, which can quickly form a strong bonding effect after being broken and mixed.

[0009] Preferably, a water bag is connected to the bottom of the blocking body, and the water bag is made of latex material.

[0010] Preferably, four protection strips are arranged around the periphery of the water bag, the protection strips extend out from the bottom of the blocking body and the two are integrated.

[0011] The beneficial effects of the utility model are as follows: (1) The sealing plug is a truncated cone, which is conducive to a better fit with the gun muzzle. A water injection port is arranged in the middle, which penetrates the sealing plug and the sealing body to the water bag, and the water injection amount can be controlled according to the actual situation on site. (2) The sealing body is a solid cylinder, and adhesive bag A and adhesive bag B are evenly distributed on the outside. Adhesive bag A contains marble glue, and adhesive bag B contains a curing agent in a suitable proportion. After the two are broken and mixed, a strong bonding effect can be quickly formed, so that the sealing body and the hole wall are better bonded together, thereby improving the sealing effect. (3) A water bag is connected to the bottom of the sealing body. The water bag is made of latex material, which has high strength and high elasticity. It not only plays the role of sealing the gun hole during blasting, but also helps to prevent dust and reduce dust. (4) Four protective strips are arranged around the outer periphery of the water bag. The protective strips can play a certain protective role on the water bag and prevent the water bag from breaking before the explosion. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The utility model is further described below in conjunction with the accompanying drawings:

[0014] exist Figure 1 A new type of integrated blasthole plugging device is disclosed, including 2 plugs, 3 plug bodies and 6 water bags. The 2 plugs are truncated cone-shaped, with a water injection port in the middle and 3 plug bodies fixedly connected at the bottom. The 3 plug bodies are solid cylinders, with 4 adhesive bags A and 5 adhesive bags B evenly distributed on the outside. The bottom of the 3 plug bodies is connected to 6 water bags, and four 7 protective strips are arranged around the outer periphery of the 6 water bags. The 2 plugs are truncated cone-shaped, with a water injection port in the middle, which runs through the 2 plugs and the 3 plug bodies to the 6 water bags. The 2 plugs are fixedly connected to the 3 plug bodies at the bottom, and the two are integrated and made of the same material, both of which are made of polyvinyl chloride. The 3 plug bodies are solid cylinders, with 4 adhesive bags A and 5 adhesive bags B evenly distributed on the outside. The 4 adhesive bags A contain marble glue, and the 5 adhesive bags B contain curing agents in a suitable proportion. After the two are broken and mixed, a strong bonding effect can be quickly formed. The bottom of the 3-sealing body is connected to the 6-water bag, which is made of latex material with high strength and high elasticity. Four 7-protection strips are arranged around the 6-water bag, which extend out from the bottom of the 3-sealing body and are integrated, and the 7-protection strips protect the 6-water bag.

[0015] When in use, first determine the actual amount of water needed by the water bag at the blasting site, then fix the water bag to the plugging body, inject a suitable amount of water from the water injection port, and fill the device into the blasthole after the blasthole is loaded. First fill the water bag into the blasthole, and then fill it into the plugging body while rotating it, so that the adhesive bag A and the adhesive bag B are completely broken by friction with the hole wall, and the internal marble glue and curing agent flow out and can be fully mixed. Keep rotating and filling until the sealing plug is completely and tightly fitted to the blasthole, and finally perform face blasting.
