Description

Technical Field

[0001] This invention belongs to the field of pumped storage power station engineering design, and in particular relates to an intelligent design method for excavation of side-type inlet / outlet of pumped storage power stations. Background Technology

[0002] Pumped-storage power stations operate in two modes: pumping and power generation. The water flow is bidirectional. For the upper reservoir, it acts as the inlet during power generation and the outlet during pumping; for the lower reservoir, it acts as the outlet during power generation and the inlet during pumping. These are referred to as the upper and lower reservoir inlets / outlets, respectively. Based on the direction of water flow, they are classified as side-type inlets / outlets and vertical shaft-type inlets / outlets. Side-type inlets / outlets are those where the pumped-storage power station's water conveyance channel connects horizontally to the reservoir. They consist of an open channel section, a reverse slope section, an anti-vortex beam section, a diffuser section, a tunnel section, and a gate well section. In the design of the side-mounted inlet / outlet excavation for a pumped storage power station, the first step is the layout of the inlet / outlet, which requires determining the location of the inlet / outlet based on topographic maps, water level parameters, and excavation parameters. The second step is the design of the excavation slopes, determining the slope ratio, height, and width of the ramps for each slope level based on the geological conditions of the inlet / outlet location. The third step is to implement measures such as slope support, drainage, and monitoring for the excavated slopes. Among these three steps, the second step is the core of the inlet / outlet excavation design. In this step, designers need to use specialized software to design the inlet / outlet slopes on the topographic map based on the slope excavation parameters, thus enabling further design steps.

[0003] In actual excavation slope design, the design work is complicated and the geological conditions are often poor or the amount of work is too large after the excavation is completed. This requires repeated excavation slope design operations, which leads to problems such as extended design cycle and low construction efficiency. In addition, due to the limited time and energy of the designers, the selection of schemes may be insufficient and the optimal scheme may be missed.

[0004] To address the above issues, it is necessary to develop an intelligent design method for excavating the side inlet / outlet of a pumped storage power station. This method would enable automatic excavation of the side inlet / outlet and obtain the excavation volume, significantly improving design efficiency and quality. Summary of the Invention

[0005] To address the problems of extended design cycles and low construction efficiency caused by cumbersome design procedures, poor geological conditions, or excessive workload in the excavation slope design of side inlets / outlets of pumped storage power stations, this invention provides an intelligent design method for the excavation of side inlets / outlets of pumped storage power stations. This method automatically excavates the side inlets / outlets based on their excavation dimensions and parameters, obtaining the corresponding workload.

The slope ratio ranges from 1:0.5 to 1:2.5, and the width of the walkway is 2-5m. Above the gate well maintenance platform, each slope is 10-15m high, and the last slope extends to the topline, with a slope ratio of 1:0.3 to 1:1.75 and a walkway width of 2-5m.

Step S413: Set the slope parameters below the selected trash rack maintenance platform at the slope line L1~L5, then connect the walkway of the open channel section and the reverse slope section, and set a twist surface at the slag collection pit to connect the slopes of the open channel section and the reverse slope section.

[0013] The present invention has the following advantages over the prior art: 1. The method of this invention, by pre-setting slope parameters and determining the location of the side inlet / outlet of the pumped storage power station on the topographic map, can automatically excavate and calculate the engineering quantity of the side inlet / outlet. After the excavation is completed, the side inlet / outlet and slope parameters can be modified and updated. The excavation layout and engineering quantity of the side inlet / outlet can be automatically updated again. This not only improves design efficiency but also significantly enhances design quality, promoting the transformation of engineering design from traditional mode to intelligent mode.

[0014] 2. The application of this invention takes a parametric intelligent model as its core. By pre-setting and dynamically associating the slope parameters to be excavated, an automated design and calculation process is constructed. This successfully solves key technical problems in traditional side-type inlet / outlet excavation design, such as the heavy reliance on manual calculations, repeated excavation and trial-and-error leading to low construction efficiency, and insufficient optimization of solutions. It realizes one-click automatic generation of design schemes, real-time linkage modification, and accurate and immediate feedback of engineering quantity and cost, which greatly improves the design quality, efficiency and scientificity.

[0015] 3. By presetting slope parameters, this invention can automatically complete the entire design process from terrain cutting and slope line generation to engineering quantity calculation after the location is determined. When any slope parameter is modified, such as slope height, slope ratio, or walkway width, the entire three-dimensional excavation model and related engineering quantities can be automatically updated, which changes the dilemma of manually remodeling and calculating in traditional design.

[0017] The present invention will now be further described with reference to the accompanying drawings and specific embodiments: To make the objectives, technical solutions, and advantages of this invention clearer and more explicit, the invention will be further described below with reference to the accompanying drawings and embodiments, and relevant terms will be explained.

[0018] Example 1: like Figures 1 to 2 As shown, an intelligent design method for excavation of side-type inlet / outlet of a pumped storage power station includes the following steps: Step S1: Set the excavation parameters for the side inlet / outlet of the pumped storage power station to be excavated as needed, and input the excavation parameters into the excavation software. The excavation parameters in this step include the form of the side inlet / outlet, the bottom slab excavation elevation of the side inlet / outlet, the number of side inlets / outlets, the axial spacing of the side inlets / outlets, the elevation of the trash rack maintenance platform, the elevation and width of the gate well maintenance platform, the length and end width of the diffusion section, the length and width of the anti-vortex beam section, the length of the slag collection pit, the slope ratio of the reverse slope section, the plane diffusion angle of the reverse slope section, the elevation of the open channel section, the length of the tunnel section, the length of the gate well section, and the width of the gate well section, etc.

[0019] Step S2: Obtain the location of the side inlet / outlet of the pumped storage power station from the topographic map in the excavation software; the specific implementation method of this step is as follows: Step S21: Determine the location area where the side inlet / outlet of the pumped storage power station needs to be set up on the topographic map of the excavation software; Step S22: Randomly select a fixed coordinate point within the location area using the mouse, and use this coordinate point as the control point coordinate of the side inlet / outlet of the pumped storage power station; Step S23: Within this location area, randomly select a fixed coordinate point using the mouse, and use the direction of the line connecting the two sets of fixed coordinate points as the axis of the side inlet / outlet of the pumped storage power station. Step S24: Determine the location of the side inlet / outlet of the pumped storage power station using the control point coordinates and axis.

[0020] Step S3: Based on the construction requirements of the side-type inlet / outlet of the pumped storage power station, set slope parameter limitation rules; the implementation method for setting slope parameter limitation rules includes: Step S31: Divide the excavation section of the side inlet / outlet of the pumped storage power station into three excavation positions: below the trash rack maintenance platform, above the trash rack maintenance platform to below the gate well maintenance platform, and above the gate well maintenance platform. Step S32: Limit the parameter ranges for the slope ratio, walkway width, and slope height at the three excavation locations: below the trash rack maintenance platform, above the trash rack maintenance platform to below the gate well maintenance platform, and above the gate well maintenance platform.

[0021] The specific implementation methods include: Below the trash rack maintenance platform, a single-level slope is installed with a slope ratio ranging from 1:0.3 to 1:1.5 and a walkway width ranging from 2 to 5 meters. From the trash rack maintenance platform to the gate well maintenance platform, each level of the slope is 10 to 15 meters high, with the last level being no less than 5 meters. When the elevation difference between the trash rack maintenance platform and the gate well maintenance platform is less than 15 meters, a single slope is used to the bottom, with a slope ratio ranging from 1:0.5 to 1:2.5 and a walkway width of 2 to 5 meters. Above the gate well maintenance platform, each level of the slope is 10 to 15 meters high, with the last level placed along the terrain line, with a slope ratio ranging from 1:0.3 to 1:1.75 and a walkway width of 2 to 5 meters. It should be noted that the slope ratio, ramp width, and slope height settings were all selected by technicians based on their past experience working with side-type inlets / outlets of pumped storage power stations. These parameters were not selected from a large number of sample parameters, which resulted in a significant discrepancy between the simulated engineering quantities and the design requirements.

[0022] Step S4: Within the slope parameter constraint rules, select the slope parameters for the current pumped storage power station's side inlet / outlet. Based on the selected slope parameters, simulate slope excavation of the pumped storage power station's side inlet / outlet in the excavation software. The specific implementation method for simulating slope excavation of the pumped storage power station's side inlet / outlet in the excavation software based on the selected slope parameters in this step includes: Step S41: Determine the method for excavating the slope below the trash rack maintenance platform; Step S42: Determine the method for excavating the slope from above the trash rack maintenance platform to below the gate well maintenance platform; Step S43: Determine the method for excavating the slope above the gate well maintenance platform.

[0023] Therefore, the specific excavation methods for each of the above steps S41 to S43 are as follows: The implementation methods for slope excavation below the trash rack maintenance platform include: Step S411: The bottom of the open channel section is excavated according to the elevation of the open channel section until the bottom of the open channel section is excavated to the position where it meets the topographic line. Step S412: Set the slope below the trash rack maintenance platform as Zone I, set the slope lines after merging the open channel section and the reverse slope section as L1 and L2 respectively, and set the slope lines after merging the anti-vortex beam section and the diffusion section as L3, L4 and L5 respectively. Step S413: Set the slope parameters below the selected trash rack maintenance platform at the slope line L1~L5, then connect the walkway between the open channel section and the reverse slope section, and set a twist surface at the slag collection pit to connect the slopes of the open channel section and the reverse slope section.

[0024] In the preferred embodiment of the present invention, a level 1 slope with a default slope ratio of 1:1 and a walkway width of 2m is placed at the slope lines L1 and L2 in the area below the trash rack maintenance platform; and a vertical slope with a walkway width of 2m is placed at the slope lines L3, L4 and L5.

[0025] The implementation methods for slope excavation from above the trash rack maintenance platform to below the gate well maintenance platform include: Step S421: Designate the slope from above the trash rack maintenance platform to below the gate well maintenance platform as Zone II; Step S422: Based on the slope line drawn in step S412, set the slope parameters from above the selected trash rack maintenance platform to below the gate well maintenance platform at slope line L1~L5.

[0026] In a preferred embodiment of the method of the present invention, in the area from above the trash rack maintenance platform to below the gate well maintenance platform, a default slope ratio of 1:0.75 and a walkway width of 2m are set at the slope lines L1 and L2, and the height of each slope step does not exceed 15m; if Zone II is eventually connected to the gate well maintenance platform, the last slope step is not less than 5m; otherwise, the last slope step is placed at the topographic line; and vertical slopes with a default slope ratio of 1:0.75, a walkway width of 2m, and a slope height of not more than 15m are placed at the slope lines L3, L4 and L5, with the last slope step not less than 5m; when the height difference from above the trash rack maintenance platform to below the gate well maintenance platform is less than 15m, a single slope is set to the bottom.

[0027] The implementation methods for slope excavation above the gate well maintenance platform include: Step S431: Set the slope above the gate well maintenance platform as Zone III, and set the slope lines of the gate well maintenance platform as L6, L7 and L8 respectively; Step S432: Set the slope parameters above the selected gate well maintenance platform at slope lines L6, L7 and L8.

[0028] In the preferred embodiment of the method of the present invention, a level 1 slope is placed at the slope lines L6, L7 and L8 in the area above the gate well maintenance platform, with a default slope ratio of 1:1, a walkway width of 2m, a slope height of 15m for each level, and the last level slope is placed at the topographic line.

[0029] Step S5: After the simulated slope excavation is completed, the excavation volume is output in real time through the excavation software; Step S6: Verify whether the output excavation volume meets the design requirements of the side inlet / outlet of the pumped storage power station. If it does, proceed to step S7; otherwise, return to step S4. Step S7: Excavate the side inlet / outlet of the pumped storage power station according to the output excavation volume.

[0030] The excavation volume specifically includes the structural base area of ​​the open channel section, reverse slope section, anti-vortex beam section, and diffusion section, as well as the slope excavation area and slope excavation volume of each area.

[0031] To facilitate better implementation, the editability of the starting slope lines in different zones will also be explained: The slope levels and slope height of Zone I are fixed, and L3, L4, and L5 are fixed as vertical slopes. The width of the walkway for L1 to L5 and the slope ratio of L1 and L2 can be modified. In Zone II, if slopes L1 and L2 are ultimately sloped to meet the topographic line, their slope grade, slope ratio, ramp width, and slope height can all be modified. If slopes L1 and L2 are ultimately sloped to the gate well maintenance platform, the slope grade, slope ratio, ramp width, and slope height of L1 to L5 can also be modified, but the final slope height must not be less than 5m. Furthermore, the slope height of the same grade of L1 to L5 must be consistent, except for the slopes of L1 and L2 that meet the topographic line, i.e., the elevation of each ramp must be consistent. In Zone III, slopes L6, L7, and L8 are all ultimately sloped to meet the topographic line. The number of slope levels, slope ratio, ramp width, and slope height can all be modified. The height of each slope level must be consistent, except for the slopes that meet the topographic line.

[0032] This invention allows for the automatic simulation of side-type inlet / outlet excavation on a topographic map after inputting excavation parameters for the side-type inlet / outlet and determining its location. Based on randomly set slope excavation parameters, the excavation can be performed automatically, simultaneously calculating the quantities of work completed. After excavation, the parameters for both the side-type inlet / outlet and the slope excavation can be modified in real-time, automatically updating the excavation layout and quantities. This invention, centered on a parametric intelligent model, constructs an automated design and calculation process by pre-setting and dynamically linking excavation design parameters. It successfully solves key technical problems in traditional side-type inlet / outlet excavation design, such as inefficiency due to reliance on manual labor and repeated trial and error, and insufficient optimization of solutions. Ultimately, it achieves one-click automatic generation of design schemes, real-time linkage modification, and accurate and immediate feedback on quantities and costs, significantly improving design quality, efficiency, and scientific rigor.
