Description

Technical Field

[0001] This utility model relates to the field of mine slope reinforcement technology, and in particular to a stepped slope reinforcement frame for open-pit mines. Background Technology

[0002] Slope reinforcement in mines is a core component of ensuring safe mining operations. Its core meaning is to improve the stability of mine slopes through artificial intervention, preventing geological disasters such as landslides and collapses. Mine slopes are sloping surfaces formed during mining operations, which are constantly exposed to the natural environment and the effects of mining activities, making them prone to instability due to their own structure and external forces. Reinforcement work is a proactive prevention and control measure targeting this risk.

[0003] Existing stepped slope reinforcement schemes for open-pit mines mostly employ a single structure, lacking a grid-like three-dimensional support system composed of transverse load-bearing beams and longitudinal distribution beams. This makes it difficult to evenly distribute the load on the slope, easily leading to localized stress concentration. Consequently, the reinforced structure has weak deformation resistance and cannot effectively resist deep slope sliding forces. Under long-term mining vibrations or natural gravity, there is still a high risk of collapse. Therefore, we propose a stepped slope reinforcement framework for open-pit mines to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a stepped slope reinforcement frame for open-pit mines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An open-pit mine stepped slope reinforcement frame includes a stepped slope body. Multiple sets of transverse bearing beams are fixedly installed on the upper surface of the stepped slope body. Multiple longitudinal distribution beams are fixedly installed on the side of each set of transverse bearing beams that are close to each other. Fixing components are provided on the outer surfaces of the multiple sets of transverse bearing beams and the interior of the stepped slope body. Multiple ecological composite layers are provided on the upper surface of the stepped slope body. Intelligent monitoring components are provided on the interior of some of the ecological composite layers, the upper surfaces of some of the longitudinal distribution beams, and the outer surfaces of the fixing components. A protective composite coating is sprayed onto the outer surface of each transverse bearing beam and the outer surface of each longitudinal distribution beam.

[0007] In a further embodiment, the fixing component includes multiple fixing slots, each set of fixing slots being respectively opened on the upper surface of multiple transverse bearing beams and inside the stepped slope body, and a support anchor is placed on the inner wall of each fixing slot.

[0008] In a further embodiment, each of the support anchors is fixedly connected to an anchor tip at its bottom end, and each of the fixing grooves is filled with concrete composite material.

[0009] In a further embodiment, the ecological composite layer includes a nutrient soil base layer, a vegetation concrete layer, and a seed layer, with the lower side of the vegetation concrete layer located above the nutrient soil base layer and the lower side of the seed layer located above the vegetation concrete layer.

[0010] In a further embodiment, the vegetation concrete layer is modified with an eco-friendly curing agent.

[0011] In a further embodiment, the intelligent monitoring component includes a stress sensor, a displacement gauge, and a temperature and humidity sensor, with the outer surface of each stress sensor fixedly installed on the outer surface of each support anchor.

[0012] In a further embodiment, the upper surface of a portion of the longitudinally distributed beam is fixedly installed to the outer surface of each displacement gauge, and the outer surface of each temperature and humidity sensor is located inside a portion of the ecological composite layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device uses a stepped slope as its foundation, with transverse load-bearing beams and longitudinal distribution beams forming a grid support. It is then reinforced with anchor bolts with anchored cones and concrete composite materials. The structure is stable and can effectively resist slope sliding forces, reducing the risk of collapse. Through the nutrient soil base layer, modified vegetation concrete layer and seed layer in the ecological composite layer, slope greening can be achieved, which helps ecological restoration. Through the stress sensor, displacement meter and temperature and humidity sensor of the intelligent monitoring component, safety and ecological data can be monitored in real time, supporting risk warning and maintenance decisions.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 In this utility model, the stepped slope reinforcement frame for open-pit mines includes a stepped slope body 1. Multiple sets of transverse bearing beams 2 are fixedly installed on the upper surface of the stepped slope body 1. Multiple longitudinal distribution beams 3 are fixedly installed on the side of each set of transverse bearing beams 2 that are close to each other. The outer surfaces of the multiple sets of transverse bearing beams 2 and the interior of the stepped slope body 1 are jointly provided with fixing components 4. Multiple ecological composite layers 6 are provided on the upper surface of the stepped slope body 1. Intelligent monitoring components 5 are jointly provided on the interior of some ecological composite layers 6, the upper surfaces of some longitudinal distribution beams 3, and the outer surfaces of fixing components 4. The outer surfaces of each transverse bearing beam 2 and each longitudinal distribution beam 3 are sprayed with a protective composite coating.

[0023] The stepped slope main body 1 serves as the basic load-bearing structure, providing a supporting base for the entire reinforcement frame and resisting the erosion and damage to the slope caused by mining and the natural environment. The transverse load-bearing beams 2 are fixedly installed on the surface of the stepped slope main body 1 to form a longitudinal load-bearing skeleton, dispersing the load on the slope. The longitudinal distribution beams 3 are connected between the transverse load-bearing beams 2 to form a grid-like frame structure, further enhancing the overall stability, uniformly transferring the slope stress, and avoiding the risk of collapse caused by local stress concentration. The two work together to form a three-dimensional reinforcement system, improving the slope's resistance to deformation. The stress sensor 501, displacement gauge 502, temperature and humidity sensor 503, and concrete composite material 404 are all existing technologies.

[0024] The fixing component 4 includes multiple fixing grooves 401. Each set of fixing grooves 401 is respectively opened on the upper surface of multiple transverse bearing beams 2 and inside the stepped slope body 1. Each fixing groove 401 has a support anchor 402 placed on its inner wall. Each support anchor 402 has an anchor tip 403 fixedly connected to its bottom end. Each fixing groove 401 is filled with concrete composite material 404.

[0025] The fixing groove 401 provides a precise installation channel for the support anchor 402 by penetrating the transverse bearing beam 2 and the stepped slope body 1, ensuring that the force direction of the support anchor 402 is consistent with the slope stability requirements. After the support anchor 402 is inserted into the fixing groove 401, the anchor tip 403 at the bottom end enhances the anchoring force on the deep soil and rock of the slope, and transfers the tension of the transverse bearing beam 2 and the longitudinal distribution beam 3 to the stable strata inside the slope, preventing the slope surface from sliding. After the concrete composite material 404 poured in the fixing groove 401 hardens, it fills the gap between the support anchor 402 and the groove wall, strengthens the connection strength between the support anchor 402 and the slope and the transverse bearing beam 2, and forms an integrated fixing structure of anchor, beam and slope, which greatly improves the pull-out resistance and overall stability of the reinforcement frame.

[0026] The ecological composite layer 6 includes a nutrient soil base layer 601, a vegetation concrete layer 602, and a seed layer 603. The lower side of the vegetation concrete layer 602 is located on the upper side of the nutrient soil base layer 601, and the lower side of the seed layer 603 is located on the upper side of the vegetation concrete layer 602. The vegetation concrete layer 602 is modified with an ecological curing agent.

[0027] The nutrient soil base layer 601 provides basic nutrients and soil environment for vegetation growth, improving the surface soil conditions of the slope. The vegetation concrete layer 602 is modified with an ecological solidifying agent, which not only retains the solidification strength of concrete to prevent surface soil loss, but also has air permeability and water retention, providing support for plant root growth. After the seed layer 603 germinates on the vegetation concrete layer 602, it forms vegetation cover, which further strengthens the surface of the slope through root entanglement. At the same time, it plays a role in soil and water conservation and ecological restoration, achieving the dual effect of engineering reinforcement and ecological protection.

[0028] The intelligent monitoring component 5 includes a stress sensor 501, a displacement meter 502, and a temperature and humidity sensor 503. The outer surface of each stress sensor 501 is fixedly installed on the outer surface of each support anchor 402. The upper surface of a portion of the longitudinal distribution beam 3 is fixedly installed on the outer surface of each displacement meter 502. The outer surface of each temperature and humidity sensor 503 is located inside a portion of the ecological composite layer 6.

[0029] Stress sensor 501 is installed on the surface of support anchor 402 to monitor the stress state of support anchor 402 in real time, and to provide timely warning of stress anomalies caused by load changes or soil loosening, thus ensuring the safety of the anchoring system. Displacement gauge 502 is fixed on longitudinal distribution beam 3 to monitor the minute displacements of transverse bearing beam 2 and longitudinal distribution beam 3, reflecting the overall deformation trend of the slope and providing data support for slope stability assessment. Temperature and humidity sensor 503 is embedded in ecological composite layer 6 to monitor soil temperature and humidity changes, guide vegetation maintenance, ensure the sustainability of ecological restoration effects, and achieve full-dimensional monitoring of the structural safety and ecological stability of the reinforcement project.

[0030] The working principle of this utility model is as follows:

[0031] Based on the stepped slope body 1, multiple sets of transverse bearing beams 2 and multiple longitudinal distribution beams 3 on its surface form a grid frame, which initially disperses the slope pressure. By placing support anchors 402 with anchor cones 403 in the fixing grooves 401 inside the transverse bearing beams 2 and the stepped slope body 1, and pouring concrete composite material 404, the frame is stably connected to the stepped slope body 1 to offset the sliding force. At the same time, an ecological composite layer 6 composed of nutrient soil base layer 601, ecological solidifying agent modified vegetation concrete layer 602 and seed layer 603 is laid on the surface of the stepped slope body 1 to achieve ecological soil stabilization. Finally, the stress sensor 501 on the support anchor 402, the displacement meter 502 on the longitudinal distribution beam 3, and the temperature and humidity sensor 503 in the ecological composite layer 6 are used to monitor the structural safety and ecological environment status in real time to ensure overall stability.
