A dam slope reinforcement device for a pumped storage power station

Abstract

The present invention belongs to the technical field of pumped-storage power stations, and specifically relates to a dam slope reinforcement device for pumped-storage power stations. The present invention has a reasonable structural design and is mainly composed of a reinforcement pad, an anchor nail, a heat pipe protection tube, a cone head, an anti-slip component, and a heat pipe component. The heat pipe protection tube, the cone head, the anti-slip component, and the heat pipe component together constitute a reinforcement assembly. The design of the cone head facilitates the smooth driving of the heat pipe protection tube into the foundation of the dam slope of the pumped-storage power station. The design of the anti-slip component prevents the heat pipe protection tube from being easily detached after being driven into the foundation.

The design of the heat pipe component allows the soil to freeze simultaneously in winter, forming a frozen zone with stable freezing strength below the grid area, cutting off the channel for water to rise, and eliminating the destructive effects of soil frost heave on the dam slope foundation.

Description

Technical Field

[0001] The present invention belongs to the technical field of pumped storage power stations, and in particular relates to a dam slope reinforcement device for a pumped storage power station. Background Art

[0002] Pumped-storage power stations use electricity during low-load periods to pump water to the upper reservoir, and release the water to the lower reservoir for power generation during peak load periods. Currently, pumped-storage power stations use reinforcement plates to reinforce the dam slopes to prevent landslides. Some reinforcement plates are generally installed by directly inserting soil nails into the soil. However, after a certain period of use, the soil nails are prone to slipping out and becoming unstable.

[0003] To this end, the patent specification with publication number CN218466460U discloses a pumped-storage power station dam slope reinforcement device, which relates to the technical field of pumped-storage power stations. The pumped-storage power station dam slope reinforcement device includes a reinforcement plate, a disc, and an anti-detachment mechanism. Two sets of symmetrically distributed clamping blocks are fixedly installed on the front side of the reinforcement plate. The reinforcement plate is provided with four sets of rectangularly distributed mounting holes. A soil insertion rod is fixedly installed at the bottom of the disc. The soil insertion rod is located in the mounting hole. The anti-detachment mechanism is provided on the soil insertion rod. The anti-detachment mechanism makes the installation of the soil insertion rod more stable. The pumped-storage power station dam slope reinforcement device allows the reinforcement plates to be spliced ​​and installed, and the reinforcement plates will not easily shift after installation, ensuring the reinforcement effect and quality of the reinforcement plates. It also facilitates the outward rotation of the strip plates, and when combined with the soil spikes, the disc will not be easily pulled out after installation, effectively ensuring the disc's soil insertion strength and the reinforcement plate's installation strength.

[0004] However, this pumped-storage power station dam slope reinforcement device still has shortcomings. It is not suitable for reliable reinforcement of pumped-storage power station dam slopes in cold regions. Pumped-storage power station dam slopes in cold regions are prone to slope sliding due to frost heave under seasonal conditions, resulting in less than ideal reinforcement results. Therefore, it is necessary to optimize and improve it. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above-mentioned problems existing in the traditional technology and provide a dam slope reinforcement device for a pumped storage power station.

[0006] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0007] The present invention provides a dam slope reinforcement device for a pumped-storage power station, comprising a reinforcement pad, anchor nails, a heat pipe protection tube, a cone head, an anti-slip component, and a heat pipe component. The reinforcement pad comprises a pad body, wherein the four corners of the pad body are provided with anchor holes cooperating with the anchor nails, the pad body is provided with a grid area, the grid area is provided with through holes for conveniently inserting the heat pipe protection tube, the bottom end of the heat pipe protection tube is installed with a cone head for facilitating its driving into the foundation, a plurality of anti-slip components are installed on the outside of the heat pipe protection tube, and the heat pipe component is installed in the interior of the heat pipe protection tube through insertion.

[0008] Furthermore, in the above-mentioned pumped storage power station dam slope reinforcement device, the reinforcement pad is made of nylon material, and metal reinforcing ribs are built into the grid area frame of the reinforcement pad.

[0009] Furthermore, in the above-mentioned pumped-storage power station dam slope reinforcement device, the heat pipe protection tube, cone head, anti-slip component and heat pipe component together constitute a reinforcement assembly, and the reinforcement assembly is distributed in a rectangular array, and the axial direction of the heat pipe protection tube is perpendicular to the slope surface of the pumped-storage power station dam.

[0010] Furthermore, in the above-mentioned pumped-storage power station dam slope reinforcement device, the heat pipe protection tube includes a protection tube body and an end plate arranged at its upper end, a threaded mounting groove is provided on the outer side of the protection tube body, and the bottom end of the threaded mounting groove extends to the end of the protection tube body away from the end plate, and a heat pipe plug-in groove is commonly provided in the end plate and the protection tube body for facilitating the plugging of the heat pipe component.

[0011] Furthermore, in the above-mentioned pumped storage power station dam slope reinforcement device, the cone head includes a cone and a mounting head connected as one body, the mounting head is arranged at the wide part of the cone, and the outer end of the mounting head is provided with a mounting screw groove inwardly cooperating with the bottom end of the protective pipe body.

[0012] Furthermore, in the above-mentioned pumped storage power station dam slope reinforcement device, the anti-slip component includes a mounting ring and an anti-slip plate that are connected as one body, the anti-slip plate is symmetrically arranged on the outside of the mounting ring, and the inside of the mounting ring is provided with a mounting screw hole that cooperates with the protective pipe body.

[0013] Furthermore, in the aforementioned pumped-storage power station dam slope reinforcement device, the heat pipe assembly includes a heat pipe and a stop plate located at its upper end. Each heat pipe core includes an evaporation section at the bottom, an insulation section in the middle, and a condensation section at the top. When the evaporation section is heated, the working fluid in the core evaporates to form steam, carrying away heat (the latent heat of evaporation of the working fluid). Under a slight pressure differential, the steam flows through the insulation section to the condensation section, releasing its latent heat and recondensing into the working fluid. The working fluid then flows back to the evaporation section along the porous material due to capillary forces, completing a closed cycle and transferring a large amount of heat from the evaporation section to the condensation section.

[0014] Furthermore, in the above-mentioned pumped storage power station dam slope reinforcement device, the reinforcement method includes the following steps:

[0015] 1) First, use anchor nails to install the reinforcement pad on the dam slope of the pumped storage power station;

[0016] 2) Pass the heat pipe protection tube through the corresponding perforations in the reinforcement pad, screw and install multiple anti-slip components on the outside of the heat pipe protection tube in sequence, and screw and install a cone head on the bottom end of the heat pipe protection tube;

[0017] 3) Use piling equipment to drive the heat pipe protection pipe into the dam slope of the pumped storage power station, and then insert the heat pipe component into the inside of the heat pipe protection pipe. By installing the heat pipe, the soil is frozen simultaneously in winter, forming a frozen zone with stable freezing strength below the grid area, cutting off the channel for water to rise and eliminating the destructive impact of soil frost heave on the dam slope foundation.

[0018] The beneficial effects of the present invention are:
