Background Technology

[0002] Transmission and transformation projects are a general term for the construction of transmission lines and the installation of transformers. The higher the voltage level of a transmission and transformation project, the greater the amount of electricity transmitted and the longer the transmission distance. Transmission and transformation projects with voltages exceeding 330,000 volts are called "ultra-high voltage transmission and transformation projects". Currently, the highest voltage level of ultra-high voltage transmission and transformation lines in operation are ±1100kV DC transmission lines and 1000kV AC transmission lines. During the construction of transmission and transformation projects, it is necessary to construct the foundations of the transmission and transformation towers.

[0003] In power transmission tower foundation projects, construction disturbances often lead to exposed soil and rock, causing soil erosion and necessitating vegetation restoration. However, the high gravel content in the construction sites makes it difficult for the soil to retain moisture, creating an environment unfavorable for vegetation growth. Furthermore, relying solely on natural restoration is time-consuming and unlikely to achieve the desired results. In addition, conventional slope protection methods on high gravel slopes present challenges such as difficulties in vegetation construction, easy loss of substrate nutrients, and poor long-term greening effects.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. In this invention, a revegetation structure and construction method for subgrade power transmission tower foundations involves constructing a slope drainage channel outside the tower foundation engineering area and building a water storage pit and a water diversion channel within the tower foundation area. Water is introduced into the water diversion channel and then into the water storage pit. Once full, the water flows out of the tower foundation. As the water flows through the tower foundation via the water diversion channel, moisture is stored in the soil of each planting hole, increasing the water storage capacity of the tower foundation area. This improves soil moisture conditions within the area disturbed by tower foundation construction, enabling vegetation restoration in the high-gravel-content power transmission tower foundation area. Therefore, this invention facilitates vegetation greening construction.

[0025] 2. In the revegetation structure and construction method for subgrade foundations of power transmission towers according to the present invention, by setting up a conveying mechanism, a water inlet mechanism, and a lifting mechanism, when water in the water storage pit is conveyed to the planting hole soil column, the water enters the inner cavity of the movable frame through the water inlet mechanism. At this time, the parts inside the lifting mechanism cooperate to drive the movable frame to move upward. The upward movement of the movable frame drives the movable frame to one end of the connecting channel. At this time, the baffle rotates, and the water in the movable frame flows into the connecting channel, and then into the planting hole soil column through the connecting channel. This facilitates the conveying of water from the water storage pit to the planting hole soil column through the movable frame when the water in the planting hole soil column is insufficient. Therefore, the present invention has a simple structure and is easy to operate. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0039] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0040] This invention provides a revegetation structure for subgrade foundations of power transmission towers, such as... Figure 1-10 As shown, it includes a slope drainage channel 1 and a tower base area with a tower base 2. Six planting hole soil columns 6 are symmetrically opened in the tower base area. A water storage pit 3 is opened in the tower base area. A water diversion channel 4 is opened between the slope drainage channel 1 and the water storage pit 3. A connecting channel 5 is opened between the water storage pit 3 and the planting hole soil columns 6. Water in the water storage pit 3 flows into the planting hole soil columns 6 through a conveying mechanism 7.

[0041] In this embodiment, a slope drainage channel 1 is constructed outside the tower base engineering area, and a water storage pit 3 and a water diversion channel 4 are constructed inside the tower base area. Water is introduced into the water diversion channel 4, enters the water storage pit 3, and flows out of the tower base after it is full. During the construction of the water diversion channel 4, the height of the outlet is ensured to be lower than that of the inlet, so that the water flows through but does not collect under the tower base. Six planting hole soil columns 6 are evenly distributed on both sides of the tower base area, so that the water diversion channel 4 passes through the water storage pit 3. When the water storage pit 3 is filled with water, the soil of each planting hole soil column 6 can store water, providing the necessary water conditions for plant growth.

[0042] Therefore, water is introduced through the water diversion channel 4 and passes through the tower base. When the water flows through the soil columns 6 of each planting hole, the water is stored in the soil of the soil column 6, increasing the water storage in the tower base area. This improves the soil moisture conditions within the range disturbed by the tower base construction and realizes the vegetation restoration in the power transmission and transformation tower base area with high gravel content.

[0043] In a further preferred embodiment of the present invention, such as Figure 3-7As shown, the conveying mechanism 7 includes a fixed frame 701, which is fixedly connected to the inner wall of the water storage pit 3 at the junction with the connecting channel 5. A movable frame 702 is symmetrically arranged on the inner wall of the water storage pit 3. A baffle 703 is rotatably connected to one end of the movable frame 702. Connecting blocks 704 are fixedly connected to both sides of the movable frame 702. A movable frame 705 is slidably connected inside the connecting block 704. Water in the water storage pit 3 enters the movable frame 702 through the water inlet mechanism 8. The movable frame 705 moves via the lifting mechanism 9. The conveying mechanism 7 also includes a top block 706 and a bottom block. 707, top block 706 and bottom block 707 are symmetrically fixed to the outer wall of movable frame 705. Top block 706 is located above bottom block 707. Connecting block 704 is located between top block 706 and bottom block 707. Connecting block 704 and movable frame 702 are slidably connected to extrusion frame 708. The bottom end of extrusion frame 708 extends to the bottom of connecting block 704. Inside movable frame 702, at the top of extrusion frame 708, push block 709 is slidably connected to push block 709. First spring 710 is connected between push block 709 and movable frame 702. One end of push block 709 is in contact with baffle 703.

[0044] In this embodiment, when water from the water storage pit 3 is transported to the planting hole soil column 6, the movable frame 702 is located at the bottom of the water storage pit 3. The baffle 703 closes one end of the movable frame 702 and is tightly attached to the inner wall of the water storage pit 3. Water enters the inner cavity of the movable frame 702. At this time, the parts inside the lifting mechanism 9 cooperate to drive the movable frame 705 to move upward. The upward movement of the movable frame 705 drives the connecting block 704 to move upward through the bottom block 707. The upward movement of the connecting block 704 drives the movable frame 702 to move upward until the movable frame 702 moves to the connecting channel 5. At one end, the fixed frame 701 is in contact with the top of the movable frame 702, preventing the movable frame 702 from moving upward. The baffle 703 is separated from the inner wall of the water storage pit 3. The movable frame 705 continues to move upward, driving the bottom block 707 to move. The displacement of the bottom block 707 pushes the squeezing frame 708 to move. The displacement of the squeezing frame 708 pushes the pushing block 709 to move, squeezing the first spring 710. The displacement of the pushing block 709 pushes the baffle 703 to rotate, so that the water in the movable frame 702 flows into the connecting channel 5, and then flows into the planting hole soil column 6 through the connecting channel 5.

[0045] When the movable frame 705 moves downward, the displacement of the movable frame 705 pushes the connecting block 704 downward through the top block 706. The downward movement of the connecting block 704 causes the movable frame 702 to move downward. At this time, the baffle 703 contacts the inner wall of the water storage pit 3 and rotates. The rotation of the baffle 703 blocks one end of the movable frame 702, so that when the water in the planting hole soil column 6 is insufficient, the water in the water storage pit 3 can be transported to the planting hole soil column 6 through the movable frame 702.

[0046] In a further preferred embodiment of the present invention, such as Figure 7-8 As shown, the water inlet mechanism 8 includes a water inlet 801, which is located on the outer wall of the movable frame 702 away from the baffle 703. A partition 802 is slidably connected inside the movable frame 702, passing through the water inlet 801. A second spring 803 is connected between the top of the partition 802 and the movable frame 702. A vertical rod 804 extending to the bottom of the movable frame 702 is fixedly connected to the bottom of the partition 802.

[0047] In this embodiment, when the movable frame 702 moves to the bottom of the water storage pit 3, the vertical rod 804 contacts the bottom of the water storage pit 3 and moves. The displacement of the vertical rod 804 causes the partition 802 to move, which squeezes the second spring 803. The displacement of the partition 802 opens the water inlet 801. When the water level in the water storage pit 3 is lower than the height of the movable frame 702, it can enter the movable frame 702 through the water inlet 801.

[0048] In a further preferred embodiment of the present invention, such as Figure 9-10 As shown, the lifting mechanism 9 includes a mounting frame 901, which is fixedly connected to the top of the water storage pit 3. A motor 902 is fixedly connected to the top of the mounting frame 901. A lead screw 903 is connected to the output end of the motor 902. A first displacement frame 904 is connected to the outer wall of the lead screw 903. A second displacement frame 905 is slidably connected to one end of the first displacement frame 904. A third displacement frame 906 is slidably connected to one end of the second displacement frame 905. A connecting frame 907 is fixedly connected to the bottom ends of the first displacement frame 904, the second displacement frame 905, and the third displacement frame 906. The bottom end of the connecting frame 907 is fixedly connected to the movable frame 705.

[0049] In this embodiment, when the movable frame 705 is moved, the motor 902 is started. The motor 902 drives the lead screw 903 to rotate. The rotation of the lead screw 903 drives the first displacement frame 904 to move. After the first displacement frame 904 moves a certain distance, it contacts the top of the second displacement frame 905, causing the second displacement frame 905 to move. After the second displacement frame 905 moves a certain distance, it contacts the top of the third displacement frame 906, causing the third displacement frame 906 to move. This allows multiple movable frames 702 to move simultaneously to one end of the connecting channel 5, facilitating the movement of the movable frame 705 and allowing water to be replenished to the planting hole soil column 6 at the same time.

[0050] In a further preferred embodiment of the present invention, such as Figure 3-7 As shown, the top of the connecting block 704 has a through groove, the inner wall of the through groove is in contact with the outer wall of the movable frame 705, the end of the pushing block 709 near the extrusion frame 708 is provided with an inclined surface, the top of the extrusion frame 708 is in contact with the inclined surface, and the baffle 703 is rotatably connected to the movable frame 702 through the connecting shaft.

[0051] In this embodiment, the movable frame 705 continues to move upward, causing the bottom block 707 to move. The displacement of the bottom block 707 pushes the extrusion frame 708 to move, and the displacement of the extrusion frame 708 pushes the push block 709 to move, causing compression on the first spring 710. The displacement of the push block 709 pushes the baffle 703 to rotate.

[0052] In a further preferred embodiment of the present invention, such as Figure 7-8 As shown, the movable frame 702 has a sliding groove inside for the partition 802 to slide.

[0053] In this embodiment, the vertical rod 804 moves in contact with the bottom of the water storage pit 3. The displacement of the vertical rod 804 causes the partition plate 802 to move, which in turn compresses the second spring 803.

[0054] In a further preferred embodiment of the present invention, such as Figure 9-10 As shown, the top of the first displacement bracket 904 is provided with a threaded hole, which matches the lead screw 903.

[0055] In this embodiment, the motor 902 drives the lead screw 903 to rotate, and the rotation of the lead screw 903 drives the first displacement frame 904 to move.

[0056] In a further preferred embodiment of the present invention, such as Figure 9-10 As shown, the top outer walls of the second displacement frame 905 and the third displacement frame 906 are both T-shaped. One end of the first displacement frame 904 is provided with a first square groove, and one end of the second displacement frame 905 is provided with a second square groove. The inner wall of the first square groove is in contact with the outer wall of the second displacement frame 905, and the inner wall of the second square groove is in contact with the outer wall of the third displacement frame 906.

[0057] In this embodiment, after the first displacement frame 904 moves a certain distance, it contacts the top of the second displacement frame 905, causing the second displacement frame 905 to move. After the second displacement frame 905 moves a certain distance, it contacts the top of the third displacement frame 906, causing the third displacement frame 906 to move.

[0059] Step 1: Assess the disturbance area of ​​the tower foundation project and develop a plan for the restoration of the degraded land, including:

[0060] Define the goals for degraded land restoration, including vegetation restoration and soil quality improvement;
