Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slope construction, in particular to a rock high slope geological hazard treatment construction drilling device and a construction method. BACKGROUND

[0002] With the rapid development of social economy, the reinforcement of multi-level and multi-type slopes on urban mountains is paid more and more attention. When the slope surface has a large inclination or the slope height is large, the probability of hazards such as weathering and peeling, rock flow and mud, falling rocks, collapse, collapse, landslide and the like will be significantly increased, and there is a great safety hazard. In order to eliminate the safety hazard, the slope needs to be reinforced, and the reinforcement method is usually to fix an anchor rod in the rock or soil layer of the slope, and in order to embed the anchor rod, a hole needs to be drilled on the slope.

[0003] According to the search, a road slope drilling device is disclosed in the publication number CN115199208B. The device includes a support and a drilling mechanism. The drilling mechanism includes a rotating cylinder, a drilling cylinder, a chisel cylinder, a chisel spring, a limiting structure, and a control device. When drilling into the soil, the driving member drives the drilling cylinder and the rotating shaft to rotate synchronously. When the drilling cylinder is stopped by a hard block in the soil, the lifting member drives the chisel cylinder to move upward by a preset distance to store the energy of the chisel spring. Then, the chisel spring releases the energy to drive the chisel head downward to chisel the hard block. When the chisel head does not break the hard block, the chisel cylinder is repeatedly driven to move upward and the chisel spring is stored. Then, the chisel spring releases the energy to chisel the hard block until the hard block is broken. Thus, when drilling into the road slope, the hard block is chiseled automatically when a hard block is encountered. After the hard block is broken, the drilling operation is resumed, and the drilling efficiency is improved.

[0004] In the above-mentioned application, the chisel head chisels the hard block by storing and releasing the energy of the chisel spring.

[0047] Specifically, when drilling the slope, the upper side of the base 15 is fixedly provided with a connecting rope, the other end of the connecting rope is connected with the electric winch, the electric winch is fixed on the top of the slope, the sliding of the base 15 on the slope surface is controlled by winding and unwinding the connecting rope by the electric winch, and after the base 15 moves to the required position, the inserting rod 808 is inserted into the slope through the opening on the surface of the base 15 to fix the base 15, so that the anchor rod drill on the base 15 can be more stable on the slope surface. When drilling, the angle of the drill rod 4 is adjusted by extending the hydraulic rod two 16, the drill rod 4 is rotated by the operation of the drilling motor 5 through the gear mechanism 6, and the hydraulic rod one 2 is extended to push the drill rod 4 to rotate and drill into the slope. When it is necessary to chisel and hit the hard rock layer, the drilling motor 5 is controlled to stop running, the rotating rod 802 is rotated upward by winding the pull rope by the winding machine 803, and after rotating to a certain height, the winding machine 803 is quickly unwound, so that the impact head 8013 rotates downward under the action of its own gravity and hits the chiseling rod 12, so that the chiseling rod 12 drives the chiseling head 10 to extend out of the drill bit 42 to chisel and hit the rock layer, thereby achieving the effect of chiseling and breaking the rock layer. Compared with the prior art, the chiseling and hitting effect on the rock layer by the rotation of the impact head 8013 is better.

[0048] Please refer to the accompanying Figure 8 -attached Figure 9 On the basis of the above embodiment, when the winding machine 803 is unwound, the rotating rod 802 rotates downward synchronously, so that the pull rope exerts a certain resistance on the rotating rod 802 when the rotating rod 802 rotates, thereby reducing the impact strength of the rotating rod 802. In order to solve the above problem, the technical scheme of the embodiment is proposed, the chiseling assembly 8 comprises a limiting top rod 805 and a limiting cylinder 806, the limiting top rod 805 is fixedly installed at the inner wall of the upper side wall of the mounting frame 13, the limiting cylinder 806 is fixedly installed on the upper side wall of the rotating rod 802, and the two sides of the limiting cylinder 806 are respectively provided with insertion holes 807.

[0049] Specifically, when chiseling, the rotating rod 802 is pulled to rotate against the limiting top rod 805 by the winding machine 803, at this time the jack 807 is rotated to align with the insertion rod 808, the insertion rod 808 is driven to extend by the magnetic adsorption force of the magnetic block and the rotating rod 802, so that the inner rod of the insertion rod 808 is inserted into the jack 807, achieving the effect of temporarily supporting the rotating rod 802, then the winding machine 803 is quickly unwound to cancel the pulling force on the connecting cylinder 804, at this time the connecting cylinder 804 slides downward along the rotating rod 802 under the action of gravity until it slides into the limiting cylinder 806, the adsorption force of the magnetic block and the rotating rod 802 is cut off by the connecting cylinder 804, so that the insertion rod 808 exits the jack 807, thereby automatically canceling the support of the rotating rod 802 after the winding machine 803 is unwound, so that the rotating rod 802 is not resisted by the pulling rope when rotating downward, thereby improving the impact potential energy of the impact block 801 and improving the chiseling effect on the rock stratum.

[0053] Specifically, the piston block three 8113 is resisted by the elastic force of the elastic telescopic rod 8114 against the outer wall of the barrel 8011, so that the main pipe 8111 is closed, when the piston block one 8012 is inserted into the barrel 8011, the fluid in the interior of the barrel 8011 acts on the piston block three 8113, so that the piston block three 8113 is lifted to open the main pipe 8111, so that the fluid enters the piston barrel one 810 through the branch pipe 8112 and the conveying pipeline and is temporarily stored, the weight of the impact block 801 is reduced, when the rotating rod 802 is rotated and resisted by the limiting top rod 805, the extrusion blocking rod 14 is resisted and pressed downward by the extrusion piece 8117, the extrusion piece 8117 drives the sliding ring 8115 to slide away from the fixed ring 8118, so that the air bag 8116 is pulled to stretch, the air bag 8116 inhales the gas in the main pipe 8111 when stretching, so that the piston block three 8113 is driven to move away from the barrel 8011 under the action of negative pressure, so that the main pipe 8111 is opened, at this time, the piston block one 8012 slides downward under the action of its own gravity and generates negative pressure in the barrel 8011, so that the fluid in the interior of the piston barrel one 810 is inhaled into the barrel 8011 again, the weight of the impact block 801 is increased, so that the impact strength is improved.

Clearing the surface, repairing the road and leveling the slope: Based on the site topography, manually construct a construction access road to the construction work surface, simultaneously deal with surface vegetation, gravel and dangerous rocks, and ensure that the construction access road is connected to the existing road. Use shovels and pneumatic picks to clear the area around the blast holes to form a flat working surface that meets the requirements of the drilling equipment. S2. Transfer equipment: Move the drilling device to the slope to be processed and fix it in place; S3. Hole layout and drilling: Determine the depth and spacing of the blast holes based on the actual ground elevation and design requirements. High-pressure airflow is output from the chisel head (10). For intact rock surfaces, use a small amount of air to blow away the floating debris. After the drill bit (42) enters the hole, gradually increase the airflow to full air and full pressure. For rock surfaces with weathered gravel layers or residual surface cracks, use yellow mud to protect the hole. Control the drilling speed when drilling hard rock. For soft rock, use full air and half pressure and lift the drill and blow the hole once every 1.0m-1.5m of drilling. Use a small amount of air and light pressure for weathered and broken layers and blow frequently to protect the hole. After each hole is drilled, blow away the rock powder in the hole, clean the rock debris and rock powder at the hole opening, and seal the hole opening after lifting the drill rod. For hard rocks in the borehole, use the chisel component (8) to break them. S4. Hole Inspection: Ensure that the hole depth and spacing deviation are within ±0.2m, and the allowable error for borehole angle deviation is 2%; S5. Blasting Operation Notice: Determine the operation time and blasting time, and inform surrounding residents and relevant on-site work units; S6. Covering and protection: Purchase brambles and process them in sections, connect them into a whole with wire. Before blasting, use a crane to fix one end of the brambles to the top of the mountain and the other end to the slope. At the same time, cover the road and bridge with a 1m thick protective soil layer, and cover the top of the soil layer with sandbags. S7. Loading and plugging: Before blasting, the on-site technical supervisor shall give technical instructions to the blasting personnel and record them; when loading, check the depth of the blast hole, load the explosive according to the design requirements, and use non-stone and non-flammable materials to tightly fill the blast hole. During the filling process, avoid damaging the detonator lead wire and impacting the detonating charge. When the hole is plugged and the detonator and detonating charge are not put in, use a blasting rod to handle it gently. S8.

S9. Detonation and Warning Signals: A safety perimeter is set up with a 500m warning range. Warning personnel clear the area from the inside out of the blast zone. After confirming that personnel and equipment have been evacuated from the danger zone, the on-site technical supervisor issues a detonation signal. The detonation station receives the signal and charges the fuse for detonation. After the blast, wait for more than 15 minutes and issue an all-clear signal after the inspection personnel confirm that it is safe. The blasting process involves issuing warning signals, detonation signals, and all-clear signals in sequence, and the methods and meanings of the signals are announced in advance. S10, post-blast inspection: after the blasting, wait for more than 15 minutes and the smoke in the foundation pit is blown away, the blasting personnel enter the site to check and fill in the blasting record; S11, blind shot processing: find the blind shot and report and process immediately, set obvious signs and take safety measures when unable to process in time; for the blind shot whose blasting network is not damaged and the minimum resistance line is unchanged, re-connect the line to detonate; when the minimum resistance line changes, calculate the safety distance and increase the warning range before connecting the line to detonate; or another parallel hole is drilled at the hole mouth not less than 10 times the hole diameter to charge and detonate; if the explosive is not water-resistant nitramine and the hole wall is intact, remove part of the filler and pour water into the hole to make the explosive ineffective for further processing; when processing the blind shot, set up warning at the boundary of the dangerous area, prohibit unrelated personnel from being present and other operations in the dangerous area, check the blast pile after processing and collect the remaining blasting equipment.
