AI Technical Summary
Before treatment, it was impossible to use machinery to clear the rock slopes of open-pit mines, making it difficult to guarantee the safety of the "spider-man" workers.
Double rows of vertical safety piles are installed at the top of the rock slope. Threaded steel bars and cement slurry are poured into the pile holes to form safety piles. Main and auxiliary safety ropes are fixed at the top of the piles to provide 3 tons of pull-out force. Combined with five-point safety belts and non-slip shoes, the operation is ensured to be safe.
It provides 3 tons of pulling force to ensure the safety of Spider-Man workers when clearing dangerous rocks and loose stones, and daily replacement of damaged ropes ensures operational safety.

Technical Field
[0001] This utility model belongs to the field of slope support engineering technology, and specifically relates to a safety pile for spider-man operations on rock slopes, in order to ensure the safety of spider-man workers on slopes. Background Technology
[0002] Currently, in open-pit mines where rock slopes formed by blasting and stripping are not suitable for mechanical cleaning before formal treatment and support are implemented, it is necessary to use "spider-men" to remove loose rocks and boulders from the slopes. To ensure the safety of the "spider-men" workers operating on the slopes, this utility model was developed. Utility Model Content
[0003] In view of the above-mentioned defects or deficiencies in the prior art, in order to solve the problems existing in the prior art, this utility model provides a safety pile for spider-man operations on rock slopes.
[0004] Its main technical solution is: a safety pile for spider-man operation on rock slopes, including a rock slope, with double rows of vertical safety piles installed at the top of the rock slope, and a main safety rope and a secondary safety rope fixed to the top of the safety piles respectively, and the tail ends of the main safety rope and the secondary safety rope are connected to a five-point safety belt.
[0005] Furthermore, the safety pile is formed by threaded steel bars installed inside the pile hole and cement slurry injected into the pile hole for bonding.
[0006] Furthermore, the safety pile is buried at a depth of 1.35m, with its top exposed by 15cm and bent at 45°.
[0007] Furthermore, the diameter of the pile hole is 42mm, and the safety pile spacing is 1.0m and the hole spacing is 3.0m.
[0008] Furthermore, the threaded steel bar is 1.5m long and φ25mm in diameter.
[0009] The beneficial effects of this utility model are as follows: This utility model provides a safety stake for spider-man operations on rock slopes, which can provide a pull-out force of 3 tons. Routine inspections ensure timely replacement of worn-out or damaged safety ropes, guaranteeing the safety of workers. Attached Figure Description

[0014] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.
[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0016] The purpose of this utility model is to provide a safety pile for spider-man operations on rock slopes, which provides a safety guarantee for spider-man workers during the initial stage of open-pit mine slope formation, whether for slope cleaning or shotcreting.
[0017] Safety stakes for spider-man operations on rock slopes include the following steps:
[0018] Before formal treatment and support are carried out on the rock slope 5 formed by open-pit mining and stripping, areas where mechanical cleaning of the slope surface cannot be carried out need to be cleared by spiders to remove dangerous rocks and loose stones. Vertical safety piles 4 are installed at the top of the rock slope 5 to provide anchoring force. Spiders wearing protective equipment and fastened with double safety ropes and firmly connected to the double rows of safety piles stand on the slope to carry out the work.
[0019] The safety pile 4 is a tension type; the pile diameter is 42mm; the row spacing of the safety piles 4 is 1.0m, and the hole spacing is 3.0m. A single 1.5m long φ25 threaded steel bar 1 is installed inside the pile hole, and cement grout 7 is poured into the pile hole to bond the φ25 threaded steel bar 1 to form the safety pile 4. The water-cement ratio should be 0.4-0.5. The safety pile 4 is buried at a depth of 1.35m, with 15cm exposed and bent at 45° to fix the main safety rope 2 and the auxiliary safety rope 3.
[0020] The spider-man must wear a five-point safety harness and two 20mm thick steel wire core safety ropes. The safety ropes have special safety locks or anti-slip safety buckles. The safety harness and ropes must meet relevant national standards. One end of the safety rope is connected to the safety harness, and the other end is anchored to a safety stake. Soft-soled, anti-slip shoes must be worn during operation.
[0021] Before construction, the safety rope must be carefully inspected to ensure that the fixing points are secure, and that the rope is free from damage or aging. The downward bends of the safety rope should be protected with a soft, abrasion-resistant material. Ropes that reach the point of being unusable should be replaced promptly.
[0022] Safety piles for spider-man operations on rock slopes are implemented as follows: Before formal support is provided, safety piles are constructed on the slope top platform; the pile diameter is 42mm; the spacing between rows of safety piles is 1.0m, and the spacing between holes is 3.0m. A single 1.5m long φ25 threaded steel bar is installed inside the pile hole. Cement grout is poured into the pile hole and bonded to the φ25 threaded steel bar to form the safety pile. The water-cement ratio should be 0.4–0.5. The safety pile is buried to a depth of 1.35m, with 15cm exposed and bent at a 45° angle to secure the main and auxiliary safety ropes.
[0023] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
