[0033] For large-span power plant of hydropower project, the main role of rock-anchored beam is to anchor the reinforced concrete beam body firmly on the rock by using a certain depth of grouting long anchor rod, and the load borne by the long anchor rod and the rock wall friction is transmitted to the rock mass. The design of rock-anchored beam does not set up column, and fully utilizes the bearing capacity of surrounding rock, compared with ordinary cast-in-place beam, this structure can narrow the span of underground plant, reduce the engineering quantity, reduce the engineering cost, and at the same time increase the stability of the cavern. But because the application of rock-anchored beam is mainly concentrated in the underground plant of large-scale water conservancy hub, which is used for the installation, maintenance and other purposes of mechanical and electrical equipment, its construction is a comprehensive construction technology integrating light surface (pre-splitting) blasting, anchoring technology, concrete technology, stress, strain and displacement measurement technology, which has high technical requirements, great construction difficulty and high construction cost, and is not conducive to popularization and application in small-span underground workshop.

[0034] For the above problems, refer to Figure 1The underground concrete aggregate screening system is provided. Figure 1 A front view structural schematic diagram of the underground concrete aggregate screening system in an embodiment of the present application is shown. The underground concrete aggregate screening system in an embodiment of the present application comprises a crane 10, a feeding mechanism 20, a screening device 30, a discharging mechanism 40 and an underground concrete aggregate screening workshop.

[0035] Continuing to refer to Figure 1 In an embodiment, the underground concrete aggregate screening workshop comprises a first chamber 100, a second chamber 200, a third chamber 300, a first support frame 600 and a second support frame 700. The first chamber 100 has a support base surface 150. The first support frame 600 comprises a support foot assembly 610 and a suspended beam mechanism 620. In combination Figure 2 As shown, one end of the support foot assembly 610 is uniformly distributed on the support base surface 150, and the other end of the support foot assembly 610 is connected with the suspended beam mechanism 620. The suspended beam mechanism 620 is used to movably mount the crane 10, and enables the crane 10 to move in a direction parallel to the support base surface 150 relative to the suspended beam mechanism 620. The second support frame 700 is arranged on the support base surface 150, and the height of the second support frame 700 along the direction perpendicular to the support base surface 150 is lower than the height of the suspended beam mechanism 620, and the second support frame 700 is used to mount the screening device 30.

[0037] The one end of the support foot assembly 610 is evenly distributed on the support base surface 150, and the other end of the support foot assembly 610 is connected with the cantilever beam mechanism 620, so that the crane 10 can be movably installed on the cantilever beam mechanism 620, and the crane 10 can move relative to the cantilever beam mechanism 620 in a direction parallel to the support base surface 150, so that the crane 10 can hoist the screening equipment 30 and perform daily operation maintenance. Specifically, the first support frame 600 can be implemented as a steel frame, and compared with the construction mode of the traditional rock anchor beam, the first support frame 600 is used as the installation base of the crane 10, so that the construction period is shorter, the construction difficulty is lower, and the cost can be effectively saved, which is beneficial to popularization and application in small-span underground workshops.

[0038] Specifically, during operation of the underground concrete aggregate screening system, the aggregate to be screened is first transported by the feeding mechanism 20 in the first chamber 100 and fed to the screening equipment 30; then the aggregate is screened by the screening operation of the screening equipment 30, and finally the finished product is output from the third chamber 300 by the discharging mechanism 40. Understandably, the height of the first chamber 100 can be adaptively set according to the height of the screening equipment 30, or the height of the second support bracket can be adjusted to adapt to the height of the first chamber 100, which will not be described here.

[0039] Optionally, the feeding mechanism 20 can be implemented as a feeding belt conveyor.

[0040] The first vibrating screen device 31 is connected with the feeding mechanism 20 and a first discharging belt conveyor 41. The first discharging belt conveyor 41 can directly output the finished product meeting the requirements from the third chamber 300 after the screening of the first vibrating screen device 31.

[0041] Optionally, the spiral sand washing device 33 is also connected with a waste belt conveyor 60, which is used for outputting waste.

[0042] Adaptively, the second support frame 700 can but not limited to include a first support table 710 and a second support table 720, the first support table 710 and the second support table 720 are arranged adjacent along the extending direction of the second central axis 700a, and the first support table 710 is arranged on the side close to the second chamber 200, the setting height of the first support table 710 along the direction perpendicular to the support base surface 150 is higher than the setting height of the second support table 720, so as to meet the arrangement requirements of the first vibrating screen device 31 and the second vibrating screen device 32.

[0043] Adaptively, in combination with Figure 2 As shown, the first chamber 100 can but not limited to also have a third side wall 130 and a fourth side wall 140 opposite to each other, and the underground concrete aggregate screening workshop further includes a fourth chamber 400, the fourth chamber 400 is arranged on one side of the first chamber 100 and communicates with the third side wall 130, and the fourth chamber 400 is used to arrange the waste belt conveyor 60, so as to meet the transportation requirements of the waste.

[0044] In addition, the first vibrating screen device 31 also has a primary screening discharge port (not shown), which communicates with the feed port (not shown) of the second vibrating screen device 32. The discharge mechanism 40 can but not limited to be implemented to include the first discharge belt conveyor 41, and further include a second discharge belt conveyor 42 and a third discharge belt conveyor 43, the second discharge belt conveyor 42 and the third discharge belt conveyor 43 are respectively connected with the two secondary screening discharge ports of the second vibrating screen device 32, so as to output different finished products through the second discharge belt conveyor 42 and the third discharge belt conveyor 43.

[0045] Preferably, continuing to refer to 2, the second chamber 200 and the third chamber 300 have a coincident third central axis 200a, so that the second chamber 200 and the third chamber 300 can be arranged in a straight line, so as to improve the efficiency of aggregate conveying and optimize the conveying route.

[0046] Optionally, the first chamber 100 has a first central axis 100a extending in the direction from the first side wall 110 to the second side wall 120, and the second support frame 700 has a second central axis 700a, the second central axis 700a deviates from and is parallel to the first central axis 100a, so that the second support frame 700 deviates from the first central axis 100a, so that a maintenance passage 100b can be formed in the first chamber 100, so as to facilitate the maintenance work of the maintenance workers.

[0047] More preferably, the third central axis 200a is parallel to the first central axis 100a, the second central axis 700a deviates from and is parallel to the first central axis 100a, and the second chamber 200 and the third chamber 300 deviate from the first central axis 100a in the same direction as the second support frame 700. This makes it easier for the loading mechanism 20 and the discharging mechanism 40 to be arranged in a position that is adapted to the screening and washing equipment 30, which helps to optimize the aggregate conveying route and improve the screening and washing efficiency.

[0048] Preferably, the third chamber 300 is along the third central axis 200a and gradually expands in the direction away from the first chamber 100, so that the first discharge belt conveyor 41, the second discharge belt conveyor 42 and the third discharge belt conveyor 43 are staggered with each other. On the one hand, it helps to meet the layout requirements of the first discharge belt conveyor 41, the second discharge belt conveyor 42 and the third discharge belt conveyor 43, and on the other hand, it helps to reduce the excavation material of the third chamber 300, thereby shortening the construction period, reducing construction costs and improving the safety of the chamber structure.

[0049] Optionally, combined Figure 1 and Figure 3 As shown, the movement mode of the crane 10 can be, but is not limited to, implemented as the suspension beam mechanism 620 being able to move relative to the support leg assembly 610 along the first direction, thereby driving the crane 10 to move along the first direction X; in addition, see Figure 3 The crane 10 can move relative to the suspension beam mechanism 620 along the second direction Y, thereby realizing the all-round movement of the crane 10 in the planar direction parallel to the supporting base surface 150, so as to ensure the preliminary lifting operation of the screening and washing equipment 30 and daily inspection and maintenance operations, such as the lifting and replacement of related screening and washing structures.

[0050] Optionally, see Figure 2 The support foot assembly 610 may include, but is not limited to, multiple support rods 611, and the multiple support rods 611 are evenly distributed along the extension direction of the side wall of the first chamber 100. This helps to make full use of the spatial characteristics of the first chamber 100, so that the support rods 611 can be arranged at the edge of the first chamber 100, reducing interference with the layout of the screening and washing equipment 30. In addition, it helps to increase the layout range of the maintenance channel 100b in the first chamber 100, ensuring that maintenance workers have sufficient walking and maintenance space, and improving maintenance convenience.

[0051] Optionally, see Figure 2The underground concrete aggregate screening and washing plant can further include a fifth chamber 500, which is arranged on one side of the first chamber 100 and is located on the same side of the fourth chamber 400 and communicates with the third side wall 130. The fifth chamber 500 is arranged in parallel with the fourth chamber 400. Specifically, the fifth chamber 500 is used for transporting slag during the excavation stage of the underground concrete aggregate screening and washing plant, and is used as an access channel for related equipment during the construction of the underground concrete aggregate screening and washing plant. In addition, the fifth chamber 500 is also used as a main access channel for maintenance personnel, thereby solving the problem of the lower passage of the underground concrete aggregate screening and washing plant during construction.

[0052] Preferably, the fourth chamber 400 and the fifth chamber 500 are arranged on the opposite side of the second central axis 700a deviated from the first central axis 100a. In this way, the arrangement of the maintenance passage 100b can be adapted to arrange the fourth chamber 400 and the fifth chamber 500 on the side close to the maintenance passage 100b, thereby facilitating the maintenance personnel to enter and exit the fifth chamber 500 and to perform maintenance work on the equipment in the fourth chamber 400.

[0053] Optionally, the underground concrete aggregate screening and washing plant can further include a feeding shaft 800, which is used to supply materials to the upward feeding mechanism 20 to meet the feeding requirements during the screening and washing operation.
