Description

Technical Field

[0001] The invention belongs to the technical field of static blasting construction, and in particular relates to a static blasting construction device and method. Background Art

[0002] Common demolition methods for rock or concrete demolition include blasting, hydraulic fracturing, and static blasting with expansion agents. Traditional blasting, however, is limited in its application due to high vibration, noise, and safety risks. Hydraulic fracturing, on the other hand, requires heavy equipment, low demolition efficiency, and high construction conditions, making it difficult to meet diverse construction needs.

[0003] As a vibration-free, noiseless and environmentally friendly demolition method, static blasting with expansive agents is becoming increasingly widely used. However, at present, the construction of expansive agents mainly relies on manual operations such as drilling, placing expansive agents, and adding water for stirring, which presents many technical problems: First, the fully manual operation process leads to low construction efficiency, making it difficult to achieve large-scale and rapid demolition; second, there is a risk of misoperation during the manual addition and stirring process, and the expansive agent is prone to splashing, affecting construction safety; third, the manual mixing of the expansive agent and water ratio is difficult to accurately control, which is prone to errors and directly affects the static blasting effect; fourth, the degree of automation is insufficient and cannot adapt to complex construction environments and continuous operation requirements. Therefore, the development of a fully automatic static blasting construction device and method that integrates the functions of drilling, placing expansive agents, and adding water for stirring has become the key to improving the efficiency and safety of static blasting construction with expansive agents.

[0036] Example 2: See attached Figures 1 to 6 , provides an illustrative embodiment of the static blasting construction method proposed by the present invention, using the static blasting construction device of Example 1, the static blasting construction method includes the following steps: S1. Place multiple expansion agent packaging units 42 into the delivery tube 41 and insert the positioning shaft 1 into a preset position on the ground to position the device; S2. Start the drilling module 3. The drilling motor 34 drives the drilling head 33 to rotate. The transmission motor 32 drives the drilling motor 34 and the drilling head 33 to move along the transmission track 31. Combined with the telescopic action of the first hydraulic device 35, a hole of a preset depth is drilled in the rock or concrete surface. Then, all components are reset. S3. Start the rotary drive mechanism 6 to rotate the delivery module 4 to the drilling position. The control system 7 calculates the required number of expansion agent packaging units 42 based on the drilling depth and the hardness of the rock or concrete. The control system 7 controls the solenoid valve 43 based on the feedback signal of the infrared sensor 44 to operate, so that the corresponding number of expansion agent packaging units 42 are discharged into the drill hole through the discharge port 412 under the action of gravity; S4. Start the rotary drive mechanism 6 and rotate the stirring and water-adding module 5 to the drilling position. The second hydraulic device 51 drives the stirring blade 53 to descend, and the breakthrough tip 54 punctures the expansion agent packaging unit 42. At the same time, the water injection pipe injects water through the water injection hole 55. The stirring drive motor 52 drives the stirring blade 53 to rotate, cooperating with the up and down reciprocating action of the second hydraulic device 51 until the expansion agent and water are evenly mixed. S5. The control system 7 coordinates the reset of each module to complete the preparation for a single static explosion.

[0037] In step S3, the control system 7 calculates the number of expansion agents to be deployed according to the following formula based on the drilling depth, the hardness grade of the rock or concrete, and the pre-stored expansion amount of the single expansion agent packaging unit 42:

[0038] in, n is the number of expansion agent packaging units 42 deployed (rounded to an integer); r is the drilling radius (mm); H is the drilling depth (mm), which is determined by the preset depth in step S2; ρ is the standard density of the expansion agent (kg / mm³); k is the hardness correction coefficient, which is obtained in real time through the rock hardness detection device: 1.0-1.2 for soft rock, 1.2-1.5 for medium-hard rock, and 1.5-2.0 for hard rock; m is the pre-stored mass (kg) of a single expansion agent packaging unit 42 .

[0039] In step S4, a flow sensor and a solenoid valve are provided on the water injection pipeline, and the control system 7 dynamically adjusts the water injection amount according to the following formula: V = V 0×(1+ δ ) in, V is the actual water injection volume (L); V 0 is the theoretical water injection volume (L, calculated based on the mass of the expansion agent and the water-cement ratio); δ is the correction coefficient, which is determined by the deviation between the actual mass of the expansion agent packaging unit 42 and the preset mass.

[0040] Specifically, the theoretical water injection volume V 0 is calculated according to the following formula: V 0= n × m × w in, n is the number of expansion agent packaging units 42, m is the pre-stored mass of a single expansion agent packaging unit 42 (kg),w is the preset water-cement ratio (L / kg).

[0041] When the actual mass of the expansion agent packaging unit 42 deviates from the preset value δ = ±5%, the control system 7 automatically adjusts the water injection volume, such as the theoretical water injection volume V 0=0.3L, δ = +5%, actual water injection volume V =0.315L, compared with adding water manually according to experience, the ratio error is significantly increased.

[0042] In step S4, a pressure sensor 533 is installed within the stirring blade 53 to monitor the resistance of the mixture in real time. When the resistance fluctuation amplitude is less than a preset threshold and lasts for more than a set time, the expansion agent and water are considered to be uniformly mixed. Specifically, the pressure sensor 533 within the stirring blade 53 monitors the resistance fluctuation and determines uniform mixing when the fluctuation amplitude is ≤±4% and lasts for 12 seconds. Compared to traditional manual visual judgment, this method ensures sufficient expansion agent hydration reaction and significantly improves the static explosion effect.

[0043] In the above-mentioned schematic embodiment, the static blasting construction method uses a control system to accurately calculate the amount of expansion agent to be added based on the hole depth and rock hardness, combines the counting feedback of the infrared sensing device to achieve quantitative addition, and dynamically judges the mixing uniformity through the pressure sensor, thereby reducing the ratio error of the expansion agent and water, significantly improving the static blasting effect, and at the same time, the fully automated process can significantly reduce the intensity of manual labor.

[0044] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
