Description

Technical Field

[0001] This application relates to the technical field of subgrade construction, and particularly relates to a slag discharging platform for a high and steep rocky slope in mountainous areas and a construction method thereof. Background Art

[0002] At present, the rocky slopes in mountainous areas are large in height and steep in terrain. The slope reaches 20 levels, the height of a single-level slope reaches 10 - 20 meters, the total height of the slope reaches more than 205 meters, the average slope of the natural terrain reaches 54°, the rock formations along the periphery of the slope are broken, and it is difficult to build an access road. The access road generally connects to the main structure of the slope and can reach the top, middle or bottom of multiple slopes. There is no road for dump trucks to reach each slope during the slope excavation process.

[0003] In the related art, cable crane towers are set on both sides of the canyon, and cable cranes and slag loading boxes are used to transport slag. However, the cable crane towers cannot be set on the canyon mountain top, and at the same time, the construction of cable cranes is difficult.

[0004] Therefore, it is necessary to design a new slag discharging platform for high and steep rocky slopes in mountainous areas to overcome the above problems. Summary of the Invention

[0005] This application provides a slag discharging platform for a high and steep rocky slope in mountainous areas and a construction method thereof, which can solve the technical problems in the related art that when transporting slag using cable cranes and slag loading boxes under the condition of no access road for rocky slopes in mountainous areas, the cable crane towers cannot be set on the canyon mountain top, and at the same time, the construction of cable cranes is difficult.

[0006] In a first aspect, an embodiment of this application provides a slag discharging platform for a high and steep rocky slope in mountainous areas, which includes: a gully, a plurality of spray systems, and a slag collecting platform. The gully is arranged on the slope and extends from the mountain top to the mountain foot; the plurality of spray systems are arranged at intervals along the height direction of the gully; the slag collecting platform includes a slag collecting site and an assembled retaining wall. The slag collecting site is located at the bottom of the gully, and the assembled retaining wall is installed on the side of the slag collecting site away from the slope.

[0007] Among them, a waste slag transfer access road connecting each slope and the corresponding gully is built using a crawler excavator and a down-the-hole drill, the waste slag of each slope is transported to the gully, and the waste slag of each slope is washed down along the gully to the slag collecting platform by using the plurality of spray systems, so that the waste slag of each level slides to the slag collecting site at the mountain foot. The converged waste slag is blocked by the assembled retaining wall, so that the waste slag is located within the slag collecting platform, ensuring the construction safety of slope slag discharging.

[0008] In combination with the first aspect, in one embodiment, the prefabricated retaining wall includes a base, the base is buried on one side of the gully, a plurality of retaining wall bodies are inserted into the base, and the plurality of retaining wall bodies are bolted to the base, and the plurality of retaining wall bodies are arranged along a direction perpendicular to the extension direction of the gully.

[0009] Wherein, prestressed steel bars are buried in the base, and part of the prestressed steel bars extend out of the base. After the plurality of retaining wall bodies are hoisted onto the base, by installing bolts at the ends of the prestressed steel bars, the plurality of retaining wall bodies are fixed to the base. At the same time, grouting material is poured into the gaps between the plurality of retaining wall bodies and the base to improve the connection stability between the plurality of retaining wall bodies and the base. When it is necessary to remove the damaged retaining wall body, the grouting material located at the damaged retaining wall body is chiseled off, and the prestressed steel bars and the bolts are released, and then the damaged retaining wall body can be replaced. The plurality of retaining wall bodies are detachably assembled to the base, so that the prefabricated retaining wall can be replaced in time when local damage occurs, avoiding the situation that the prefabricated retaining wall cannot be used due to local damage and cannot provide protection. The height of the plurality of retaining wall bodies can be set to 4-5m.

[0010] In combination with the first aspect, in one embodiment, the base is provided with docking interfaces, and a plurality of retaining wall bodies are inserted into the docking interfaces.

[0011] Wherein, the extension direction of the docking interface is perpendicular to the extension direction of the gully. The plurality of retaining wall bodies are inserted into the base through the docking interfaces, so that the contact area between the plurality of retaining wall bodies and the base is increased, and the connection stability between the plurality of retaining wall bodies and the base is improved. The depth of the docking interface can be set to 1-2m, which is convenient for inserting the retaining wall body into the docking interface during the construction of the prefabricated retaining wall, and at the same time ensuring the anti-overturning property of the retaining wall body.

[0012] In combination with the first aspect, in one embodiment, a plurality of tires are provided on one side of the retaining wall body close to the gully.

[0013] Wherein, a plurality of the tires are arranged on one side of the retaining wall body close to the gully, reducing the impact force of the waste slag on the prefabricated retaining wall and prolonging the service life of the prefabricated retaining wall.

[0014] In combination with the first aspect, in one embodiment, the retaining wall body includes an enlarged part and a supporting part which are connected to each other. The enlarged part is inserted into the base, and the enlarged part is provided with a plurality of bolt installation grooves, and a plurality of the tires are arranged on one side of the supporting part close to the gully.

[0015] Among them, the cross-section of the enlarged part can be set as a right trapezoid. The enlarged part is inserted into the base, increasing the contact area between the prefabricated retaining wall and the base, and further improving the connection stability between multiple retaining wall bodies and the base. The end of the prestressed steel bar passes through the bolt installation groove, and the prestressed steel bar is bolted to the bolt in the bolt installation groove to fix the enlarged part to the base. In other embodiments, the cross-section of the enlarged part can be set as an isosceles trapezoid or other shapes with inclined surfaces.

[0016] Combined with the first aspect, in an implementation manner, multiple retaining wall bodies are arranged at intervals.

[0017] Among them, the gap between two adjacent retaining wall bodies can be set to 0.1 - 0.2 m. Multiple retaining wall bodies are arranged at intervals, enabling the local replacement of the prefabricated retaining wall in a timely manner in case of local damage, and at the same time ensuring that the prefabricated retaining wall can block the waste slag and prevent the waste slag from entering the existing road.

[0018] Combined with the first aspect, in an implementation manner, a sedimentation tank is provided at the bottom of the slag collection platform.

[0019] Among them, the sedimentation tank is used to sediment the wastewater generated by multiple spray systems for subsequent reuse, and the sedimentation tank can be set as a three-stage sedimentation tank.

[0020] Combined with the first aspect, in an implementation manner, multiple layers of gabions are provided on both sides of the gully.

[0021] Among them, multiple layers of gabions are locally arranged on both sides of the gully to locally trim the gully. The multiple layers of gabions play a role in trimming the alignment of the gully. Demonstratively, the multiple layers of gabions can be set in a stepped shape, and the length of the multiple layers of gabions is adjusted according to the terrain. The gabion is formed by stacking multiple layers of stones from bottom to top, welding a steel reinforcement cage around each layer of stones, and tying a wire mesh outside the steel reinforcement cage. The steel reinforcement cage can be set as a cuboid, and the multiple layers of stones can be set as two layers of stones, three layers of stones or more layers of stones. Multiple-level slopes are arranged step by step from top to bottom along the extension direction of the gully. The first-level slope is set at a position close to the top of the gully, gabions are provided on both sides of the gully corresponding to the first-level slope, gabions are provided on both sides of the gully corresponding to the third-level slope, and gabions are provided on both sides of the gully corresponding to the fifth-level slope to adjust and optimize the trajectory of the waste slag falling and ensure that the waste slag enters the slag collection platform. In other embodiments, the gabions can be provided on both sides of the gully corresponding to other different-level slopes.

[0022] Combined with the first aspect, in an implementation manner, the spraying radius of each spray system is greater than or equal to 60 m.

[0023] Among them, the spray system is in an always-on state before slag discharge, during slag discharge, and after slag discharge. The spray system moistens the gully before slag discharge, and during slag discharge, it plays a role in flushing the slag along the gully onto the slag collection platform and also plays a role in dust reduction. The spraying radius of each spray system is greater than or equal to 60 m to ensure that the water sprayed by each spray system can cover the gully.

[0024] Second, the embodiment of the present application provides a construction method for a slag discharge platform of a mountainous high-steep rocky slope. The construction method includes the following steps:

[0025] The first step: Transport the slag from each level of the slope to above the corresponding gully.

[0026] The second step: Start multiple spray systems and flush the slag along the gully onto the slag collection platform.

[0027] The third step: Transport the slag to the designated slag dump to complete the slope slag discharge.

[0028] Among them, after the slope is blasted and excavated, first use a loader to transport the slag from each level of the slope to above the corresponding gully. Before slag discharge, start multiple spray systems to moisten the gully. The slag from each level of the slope falls onto the slag collection site under its own weight and the action of multiple spray systems, and is enclosed within the range of the slag collection site by the prefabricated retaining wall, separating the slag from the existing road. Multiple spray systems can effectively reduce the dust generated by the slag. The wastewater generated by multiple spray systems enters the sedimentation tank. Finally, use a loader and a muck truck to transport the slag to the designated slag dump to complete the slope slag discharge.

[0029] The beneficial effects brought by the technical solution provided by the embodiment of the present application include:

[0030] By arranging multiple spray systems at intervals along the height direction of the gully on one side of the gully and setting a slag collection platform at the bottom of the gully, the slag can be flushed along the gully onto the slag collection platform. By installing a prefabricated retaining wall on the side of the slag collection site far from the slope, the slag is located within the slag collection platform, ensuring the construction safety of slope slag discharge, and solving the technical problems in the related art that when transporting slag using a cable crane and a slag loading box for a mountainous rocky slope without an access road, the cable tower of the cable crane cannot be set on the canyon mountain top, and at the same time, the construction difficulty of the cable crane is relatively large.

[0040] The embodiments of the present application provide a slag discharging platform and a construction method for high-steep rocky slopes in mountainous areas, which can solve the technical problems that when using a cable crane and a slag loading box to transport slag on a rocky slope in a mountainous area without an access road, the cable tower of the cable crane cannot be set on the canyon top, and at the same time, the construction difficulty of the cable crane is relatively large.

[0041] See Figures 1-3As shown in the figure, an embodiment of the present application provides a slag discharging platform for a high-steep rocky slope in mountainous areas, which includes: a gully 1, a plurality of spraying systems 2, and a slag collecting platform 3. The gully 1 is arranged on the slope and extends from the mountaintop to the foot of the mountain; the plurality of spraying systems 2 are arranged at intervals along the height direction of the gully 1; the slag collecting platform 3 includes a slag collecting site 31 and a prefabricated retaining wall 32. The slag collecting site 31 is located at the bottom of the gully 1, and the prefabricated retaining wall 32 is installed on the side of the slag collecting site 31 away from the slope.

[0042] In this embodiment, a waste slag transfer access road connecting each level of the slope and the corresponding gully 1 is built by using a crawler excavator and a down-the-hole drill, and the waste slag of each level of the slope is transported to the gully 1. The waste slag of each level is washed down along the gully 1 to the slag collecting platform 3 by using the plurality of spraying systems 2, so that the waste slag of each level slides to the slag collecting site 31 at the foot of the mountain. The converged waste slag is blocked by the prefabricated retaining wall 32, so that the waste slag is located within the slag collecting platform 3, ensuring the construction safety of slope slag discharging.

[0043] In this embodiment, by arranging a plurality of the spraying systems 2 at intervals along the height direction of the gully 1 on one side of the gully 1 and arranging the slag collecting platform 3 at the bottom of the gully 1, the waste slag can be washed down along the gully 1 to the slag collecting platform 3. By installing the prefabricated retaining wall 32 on the side of the slag collecting site 31 away from the slope, the waste slag is located within the slag collecting platform 3, ensuring the construction safety of slope slag discharging, and solving the technical problems in the related art that when using a cable crane and a slag loading box to transport slag on a mountainous rocky slope without an access road, the cable tower of the cable crane cannot be set on the canyon mountaintop, and at the same time, the construction difficulty of the cable crane is relatively large.

[0044] Further, as shown in Figures 2-4 In some embodiments, the prefabricated retaining wall 32 includes a base 321 buried on one side of the gully 1. A plurality of retaining wall bodies 322 are inserted into the base 321, and the plurality of retaining wall bodies 322 are bolted to the base 321.

[0045] In this embodiment, prestressed steel bars 324 are embedded in the base 321, and part of the prestressed steel bars 324 extend out of the base 321. After multiple retaining wall bodies 322 are hoisted onto the base 321, by installing bolts 325 at the ends of the prestressed steel bars 324, the multiple retaining wall bodies 322 are fixed to the base 321. At the same time, grouting material is poured into the gaps between the multiple retaining wall bodies 322 and the base 321 to improve the connection stability between the multiple retaining wall bodies 322 and the base 321. When it is necessary to remove the damaged retaining wall body 322, the grouting material located at the damaged retaining wall body 322 is chiseled off, and the prestressed steel bars 324 and the bolts 325 are released, so that the damaged retaining wall body 322 can be replaced. The multiple retaining wall bodies 322 are detachably assembled on the base 321, so that the assembled retaining wall 32 can be replaced in time when local damage occurs, avoiding the assembled retaining wall 32 from being unable to be used due to local damage and unable to provide protection. The height of the multiple retaining wall bodies 322 can be set to 4 - 5m.

The depth of the docking interface can be set to 1 - 2m, which is convenient for inserting the retaining wall body 322 into the docking interface during the construction of the assembled retaining wall 32 and ensuring the anti-overturning property of the retaining wall body 322.

[0048] Further, referring to Figure 4 and Figure 5 As shown, in some embodiments, a plurality of tires 323 are provided on one side of the retaining wall body 322 close to the gully 1.

[0049] In this embodiment, a plurality of the tires 323 are arranged on one side of the retaining wall body 322 close to the gully 1, reducing the impact force of the waste residue on the assembled retaining wall 32 and extending the service life of the assembled retaining wall 32.

[0050] Further, referring to Figures 4-6 As shown, in some embodiments, the retaining wall body 322 includes an enlarged part and a supporting part connected to each other. The enlarged part is inserted into the base 321, and the enlarged part is provided with a plurality of bolt installation grooves. A plurality of the tires 323 are arranged on one side of the supporting part close to the gully 1.

[0051] In this embodiment, the cross-section of the enlarged portion can be set as a right trapezoid. The enlarged portion is inserted into the base 321, so that the contact area between the prefabricated retaining wall 32 and the base 321 is increased, further improving the connection stability between the plurality of retaining wall bodies 322 and the base 321. The end of the prestressed steel bar 324 passes through the bolt installation groove, and the prestressed steel bar 324 is bolted to the bolt 325 in the bolt installation groove, so that the enlarged portion is fixed to the base 321. In other embodiments, the cross-section of the enlarged portion can be set as an isosceles trapezoid or other shapes with inclined surfaces.

[0052] Further, referring to Figure 5 and Figure 6 As shown, in some embodiments, the plurality of retaining wall bodies 322 are arranged at intervals.

[0053] In this embodiment, the gap between two adjacent retaining wall bodies 322 can be set to 0.1 - 0.2 m. The plurality of retaining wall bodies 322 are arranged at intervals, so that the prefabricated retaining wall 32 can be locally replaced in time when local damage occurs, and at the same time, it is ensured that the prefabricated retaining wall 32 can block the waste slag and prevent the waste slag from entering the existing road.

[0054] Further, referring to Figures 1-3 As shown, in some embodiments, a sedimentation tank 4 is provided at the bottom of the slag collection platform 3.

[0055] In this embodiment, the sedimentation tank 4 is used to precipitate the wastewater generated by the plurality of spray systems 2, so that the precipitated wastewater can be reused. The sedimentation tank 4 can be set as a three-stage sedimentation tank 4.

[0056] Further, referring to Figure 1 As shown, in some embodiments, multiple layers of gabions are provided on both sides of the gully 1.

[0057] In this embodiment, multiple layers of the gabions are locally arranged on both sides of the gully 1 to locally trim the gully 1. The multiple layers of gabions play a role in trimming the alignment of the gully 1. Exemplarily, the multiple layers of gabions can be arranged in a stepped shape. The length of the multiple layers of gabions is adjusted according to the terrain. The gabions are formed by stacking multiple layers of stones from bottom to top, welding steel cages around each layer of stones, and tying wire meshes on the outer sides of the steel cages. The steel cages can be arranged in a cuboid shape. The multiple layers of stones can be two layers of stones, three layers of stones, or more layers of stones. Multiple-level slopes are arranged step by step from top to bottom along the extending direction of the gully 1. The first-level slope is arranged at a position close to the top of the gully 1. Gabions are arranged on both sides of the gully 1 corresponding to the first-level slope, on both sides of the gully 1 corresponding to the third-level slope, and on both sides of the gully 1 corresponding to the fifth-level slope to adjust and optimize the trajectory of the waste slag falling, and ensure that the waste slag enters the slag collection platform 3. In other embodiments, the gabions can be arranged on both sides of the gully 1 corresponding to other different-level slopes.

[0058] Further, as shown in Figure 1 In some embodiments, the spraying radius of each spraying system 2 is greater than or equal to 60 m.

[0059] In this embodiment, the spraying system 2 is in an always-on state before slag discharging, during slag discharging, and after slag discharging. The spraying system 2 plays a role in wetting the gully 1 before slag discharging. The spraying system 2 plays a role in flushing the waste slag along the gully 1 to the slag collection platform 3 during slag discharging, and meanwhile plays a role in dust reduction. The spraying radius of each spraying system 2 is greater than or equal to 60 m to ensure that the water sprayed by each spraying system 2 can cover the gully 1.

[0060] As shown in Figure 1 This application embodiment provides a construction method for a waste discharging platform on a high-steep rocky slope in mountainous areas. The construction method includes the following steps:

[0061] The first step: Transport the waste slag of each level of slope to above the corresponding gully 1.

[0062] The second step: Start multiple spraying systems 2 and flush the waste slag along the gully 1 to the slag collection platform 3.

[0063] The third step: Transport the waste slag to the designated waste slag yard to complete the waste discharging on the slope.

[0064] In this embodiment, after the slope is excavated by blasting, first use a loader to transport the waste slag of each level of the slope to the upper part of the corresponding gully 1. Before dumping the waste slag, start multiple spray systems 2 to moisten the gully 1. The waste slag of each level of the slope falls into the slag collection site 31 under the action of its own weight and multiple spray systems 2, and is surrounded by the assembled retaining wall 32 within the range of the slag collection site 31, separating the waste slag from the existing road. Multiple spray systems 2 can effectively reduce the dust generated by the waste slag. The wastewater generated by multiple spray systems 2 enters the sedimentation tank 4. Finally, use a loader and a muck truck to transport the waste slag to the designated waste dump to complete the slope slag removal.
