Description

Technical Field

[0001] This specification relates to the field of underwater blasting construction technology, and in particular to a method and device for bundling the lead wires of underwater blasting electronic detonators. Background Technology

[0002] Electronic detonators, also known as digital electronic detonators, digital detonators, or industrial digital electronic detonators, are electric detonators that use electronic control modules to control the detonation process. Due to their high safety and precise delay control, electronic detonators are widely used in underwater blasting.

[0003] Drilling and blasting is a common underwater blasting method. Underwater drilling and blasting requires a guide tube to assist in lowering the drill rod for drilling and loading explosives. For operation areas with large drilling depths and rapid currents, the guide tube and drill rod need to be extended in sections to meet the requirements for drilling and loading explosives. To ensure stable detonation, a single borehole typically holds two or more electronic detonators, each detonated by a water-resistant and tensile-stretcher lead.

[0004] However, due to the influence of water erosion and borehole depth, the long lead wires of detonators have low collection efficiency, and the contact points between the lead wires and the borehole opening, as well as the contact points between the lead wires and the hull, are prone to breakage due to friction. Drilling and blasting often involves multiple rows of boreholes being detonated in a single blast. For water operations, especially offshore operations, the effective construction window is short, making the problem of long lead wires from multiple boreholes even more prominent, severely impacting the efficiency of explosive loading operations. Summary of the Invention

[0005] In view of the shortcomings of the prior art, one object of this specification is to provide a method and device for bundling electronic detonator leads for underwater blasting. The bundling is efficient and reliable, which can improve the efficiency of underwater charging, reduce the scouring of detonator leads by water flow, and ensure the safety of underwater drilling and blasting.

[0006] To achieve the above objectives, this specification provides a method for bundling the leads of an underwater explosive electronic detonator, comprising the following steps:

[0007] The guide tube is lowered and drilled; the guide tube has through holes on its wall, which form blast holes after drilling.

[0008] A propellant cartridge and an electronic detonator are loaded into the borehole along the guide tube; the propellant cartridge is secured with a protective rope, one end of which extends out of the borehole; the electronic detonator is connected to a lead wire extending out of the borehole, and the lead wire is secured to the protective rope with waterproof tape;

[0009] Remove the guide tube and take the lead wire and protective rope out of the through hole;

[0010] Bundle the lead wires together; connect all the lead wires of the blast holes in parallel to one end of the main line using wire clips; tie the main line to the protective rope with waterproof tape; after covering all the wire clips with waterproof bags, tie them to the float; and connect the other end of the main line to the detonator.

[0011] In a preferred embodiment, in the step of lowering the guide pipe and drilling, after the drilling and blasting vessel is anchored and positioned, the guide pipe is lowered to the riverbed surface using a lifting mechanism according to the design coordinates of the blast hole. After the drill rod is lowered to the riverbed surface along the guide pipe, drilling begins to the design depth of the blast hole. The length of the guide pipe is extended according to the riverbed elevation, and the length of the drill rod is extended according to the depth of the blast hole.

[0012] In a preferred embodiment, after drilling to the designed depth of the blast hole, the lifting mechanism is used to sequentially lift multiple sections of the drill rod while keeping the guide tube in place, so that the guide tube serves as a channel for lowering the explosive cartridge; the number of the lifting mechanisms is greater than or equal to four.

[0013] In a preferred embodiment, the protective rope is a tensile nylon rope; the explosive roll is selected from water-resistant water-gel explosives.

[0014] In a preferred embodiment, during the step of loading the explosive charge and electronic detonator, the explosive charge is continuously and slowly placed into the borehole along the guide tube, and the protective rope is tightened; after the explosive charge is lowered to the bottom of the borehole, the borehole is blocked with gravel, and the protective rope is pulled up at the same time.

[0015] In a preferred embodiment, during the step of dismantling the guide pipe, the guide pipe is first raised to a suitable height, and a C-hook is used to pull the lead wire and safety rope together from the through hole onto the drill and blast vessel. Then, the guide pipe is raised further until the connecting joint of the guide pipe rises to the operating platform. The guide pipe above the connecting joint is then dismantled, and the lead wire and safety rope are pulled out from the lower end of the dismantled guide pipe onto the drill and blast vessel. This process is repeated until all sections of the guide pipe are dismantled, and the lead wire and safety rope of each blast hole are collected on the drill and blast vessel.

[0016] In a preferred embodiment, during the step of bundling the lead wires, the other end of the busbar is connected to the detonator and placed on the drilling and blasting vessel; the buoy is thrown onto the water surface, and after the drilling and blasting vessel sails to a safe area and implements safety precautions, the detonator is charged and detonated.

[0017] As a preferred embodiment, a flexible sleeve is used to protect the contact position between the lead wire and the borehole opening, as well as the contact position between the main line and the drilling and blasting vessel.

[0018] In a preferred embodiment, the inside of the wire clamp is coated with waterproof silicone grease, the outside of the wire clamp is wrapped with electrical tape, and finally a waterproof bag is placed over all the wire clamps.

[0019] This specification also provides an underwater explosive electronic detonator lead bundle device, comprising:

[0026] The underwater blasting electronic detonator lead bundle method provided in this embodiment provides guidance and constraint through a lowered guide tube, offering a lowering channel for drilling tools and ensuring drilling positioning accuracy; it also provides a channel for the explosive charge, ensuring the charge is smoothly lowered to the bottom of the borehole. Through holes are provided on the wall of the guide tube to drain water from the tube, reducing the impact of water level pressure difference on the guide tube's positioning accuracy; simultaneously, the through holes serve as outlets for the detonator lead and protective rope, facilitating their collection and improving explosive loading efficiency.

[0027] Furthermore, after all the lead wires are collected, the wire clips are tied to the float, and waterproof bags are placed over all the wire clips to ensure the stability of the detonation.

[0045] Please see Figure 1 This application provides a method for bundling the leads of an underwater explosive electronic detonator, comprising the following steps:

[0046] Step S10: Lower the guide tube 3 and drill holes.

[0047] Specifically, such as Figure 2 As shown, a through hole 4 is provided on the wall of the guide tube 3. After drilling, a hole is formed as shown. Figure 3 The borehole 9 is shown.

[0048] In step S10, as Figure 2As shown, after the drill and blast vessel 5 is anchored and positioned, the guide pipe 3 is lowered to the riverbed surface 6 using a lifting mechanism according to the design coordinates of the blast hole 9. The drill rod 2 is then lowered along the channel inside the guide pipe 3 to the riverbed surface 6, and drilling begins to the design depth 1 of the blast hole 9. Both the guide pipe 3 and the drill rod 2 are designed with multi-section connections. The length of the guide pipe 3 is extended according to the elevation of the riverbed surface 6, and the length of the drill rod 2 is extended according to the depth of the blast hole 9. The actual depth of the drilled blast hole 9 can be slightly greater than the design depth 1.

[0049] After drilling to the designed depth 1 of the blast hole 9, the multi-section drill rod 2 is lifted out in sequence by a lifting mechanism, keeping the guide tube 3 in place, so that the guide tube 3 can serve as the channel for the lowering of the explosive cartridge 10 and the crushed stone 11.

[0050] To further improve the efficiency of the charging operation, the drilling rig can be equipped with multiple lifting mechanisms, such as no less than four lifting mechanisms, which can simultaneously drill multiple boreholes 9 to reduce the connection time between the guide tube 3 and the drill rod 2.

[0051] Step S20: Insert the explosive cartridge 10 and the electronic detonator 7 into the borehole 9 along the guide tube 3.

[0052] Specifically, the electronic detonator 7 is connected to a lead wire 12 extending out of the borehole 9, such as... Figure 7 As shown, the lead wire 12 is tied to the protective rope 13 with waterproof tape. One end of the protective rope 13 extends out of the blast hole 9 and is subsequently bundled onto the drill and blast vessel 5 in step S30.

[0053] In this embodiment, the explosive cartridge 10 is selected from water-resistant water-gel explosives. The explosive cartridges 10 are connected sequentially and secured with a protective rope 13. The tail of the processed explosive cartridge 10 is connected using the protective rope 13, and the lead wire 12 of the electronic detonator 7 is loosely tied to the protective rope 13 with waterproof tape to prevent damage to the lead wire 12 during the lowering of the explosive cartridge 10. The wire clip at the end of the lead wire 12 can be waterproofed. An initiator 8 may be provided outside the electronic detonator 7.

[0054] Preferably, the protective rope 13 is a tensile nylon rope, which can prevent the tension force from damaging the lead wire 12.

[0055] In step S20, as Figure 3 As shown, during loading, the propellant cartridge 10 is continuously and slowly lowered into the borehole 9 along the channel inside the guide tube 3, while the protective rope 13 is tightened. Handle the propellant cartridge 10 gently during loading to avoid collisions with the wall of the guide tube 3. After the propellant cartridge 10 is lowered to the bottom of the borehole 9, the borehole 9 is blocked with gravel 11. The protective rope 13 is then pulled with appropriate force to confirm that the propellant cartridge 10 is fully inserted into the borehole. The guide tube 3 is then lifted to complete the loading operation.

[0056] Step S30: Remove the guide tube 3 and take out the lead wire 12 and the protective rope 13 from the through hole 4.

[0057] In step S30, as Figure 4 and Figure 5 As shown, after the explosive charge is loaded, the guide pipe 3 is first raised to a suitable height. A C-hook is then used to pull the lead wire 12 and safety rope 13 together from the through hole 4 onto the drill-and-blast vessel 5. The guide pipe 3 is then raised further until the connecting joint of the guide pipe 3 reaches the drilling rig's operating platform. The section of the guide pipe 3 above the connecting joint is then removed, and the lead wire 12 and safety rope 13 are pulled from the lower end of the removed guide pipe 3 onto the drill-and-blast vessel 5. This process is repeated until all sections of the guide pipe 3 are removed. Finally, the lead wire 12 and safety rope 13 for each blast hole 9 are collected onto the drill-and-blast vessel 5.

[0058] Step S40: Bundle the lead wires 12 together.

[0059] In step S30, all the tow lines 12 and protective ropes 13 of all the blast holes 9 are bundled together on the drill and blast vessel 5. In step S40, as... Figure 6 and Figure 8 As shown, based on the designed number of single-detonation boreholes 9, after all boreholes 9 are charged, the lead wires 12 of all boreholes 9 are connected in parallel to one end of the main line 14 using wire clips. The detonation main line 14 is then loosely tied to the protective rope 13 using waterproof tape. After waterproof bags are placed over all wire clips, they are tied to the float 15. That is, all the lead wires 12 of the boreholes 9 are connected in parallel to the blasting main line 14 using wire clips and then bundled on the float 15. The other end of the main line 14 is connected to the detonator.

[0060] Specifically, the other end of the main line 14 is connected to the detonator and placed on the drilling and blasting vessel 5. After the blasting network (i.e., lead wire 12, main line 14, detonator, etc.) is connected, the float 15 is thrown onto the water surface. After the drilling and blasting vessel 5 sails to a safe area and implements safety precautions, the detonator is charged and detonated, sequentially detonating the explosive charge 10 in the borehole 9 through the main line 14, lead wire 12, electronic detonator 7, and detonator 8, thereby completing the underwater drilling and blasting electronic detonator lead wire clustering and blasting operation. The detonator is charged and detonated.

[0061] In this embodiment, a flexible sleeve is used to protect the contact position between the lead wire 12 and the borehole 9, as well as the contact position between the busbar 14 and the drill and blast vessel 5, to prevent the influence of water flow and contact wear on the detonation network.

[0062] Preferably, the inside of the wire clamp is coated with waterproof silicone grease, the outside of the wire clamp is wrapped with electrical tape, and finally a waterproof bag is placed over all the wire clamps. These three waterproof measures ensure the stability of the detonation.

[0063] The underwater blasting electronic detonator lead bundle method provided in this embodiment provides a guiding constraint through the lowering guide tube 3, offering a lowering channel for drilling tools and ensuring drilling positioning accuracy; it also provides a channel for charging explosives, ensuring the explosive cartridge 10 is smoothly lowered to the bottom of the borehole 9. The guide tube 3 has through holes 4 on its wall to drain water from the tube, reducing the impact of water level pressure difference on the positioning accuracy of the guide tube 3; simultaneously, the through holes 4 serve as outlets for the detonator lead 12 and protective rope 13, facilitating their collection and improving charging efficiency.

[0064] Furthermore, after all the lead wires 12 are collected, the wire clips are tied to the float 15, and waterproof bags are placed over all the wire clips to ensure the stability of the detonation. The lead wires 12 and main wires 14 of the electronic detonator 7 are both tied to the protective rope 13 with waterproof tape to prevent the tension from damaging the lead wires 12 and main wires 14.

[0065] In summary, this underwater blasting electronic detonator lead bundle method is efficient and reliable, which can improve the efficiency of underwater charging, reduce the scouring of the detonator lead 12 by the water flow, and ensure the safety of underwater drilling and blasting. It has the advantages of simple process, strong operability, and high lead bundle efficiency, and is suitable for underwater blasting construction.

It should be noted that the device of this embodiment can perform the steps in the above method. For detailed description of the relevant content, please refer to the above method section, which will not be repeated here.

[0067] Specifically, the underwater blasting electronic detonator lead wire bundle device includes a guide tube 3, a drill rod 2, a protective rope 13, a main line 14, and a float 15.

[0068] The guide tube 3 has through holes 4 on its wall. The drill rod 2 is used to drill multiple blast holes 9 as needed. Each blast hole 9 contains a charge cartridge 10 and an electronic detonator 7, with the electronic detonator 7 connected to lead wires 12 extending out of the blast hole 9. A protective rope 13 is used to secure the charge cartridge 10. One end of the protective rope 13 extends out of the blast hole 9. The lead wires 12 are secured to the protective rope 13 with waterproof tape. There is one main line 14, with multiple lead wires 12 connected in parallel to one end of the main line 14 via wire clips. The other end of the main line 14 is connected to the detonator. The main line 14 is secured to the protective rope 13 with waterproof tape. Multiple wire clips are covered with waterproof bags and secured to floats 15.
