Abstract
Description
Technical Field
[0001] This invention relates to the field of power tower foundation protection technology, specifically to a power tower foundation protection structure. Background Technology
[0002] Transmission lines are generally long and often located in mountainous areas. The base of the towers needs to be protected to prevent rainwater erosion and excessive vegetation growth that could affect the tower base. In this case, existing technologies often use methods such as setting up protective fences, paving bricks, or pouring concrete to solve the above problems. However, protective fences can only prevent rainwater erosion and excessive vegetation growth to a certain extent. When paving bricks, weeds can grow in the gaps between adjacent bricks. Excessive weed growth can push up the bricks. Pouring concrete can completely seal the soil and rock layers, but the construction cost is high and it is not conducive to environmental protection. Summary of the Invention
[0003] In view of this, the present invention proposes a protective structure for the base of an electric tower to control the growth rate of vegetation and achieve the purpose of water and soil moisture retention.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A protective structure for a power tower base includes a tower base and a power tower installed on the tower base, and also includes a protective structure arranged around the outer ring of the tower base, the protective structure including paving bricks, pressing bricks, drainage channels, anchor bolts and water supply pipes;
[0006] The paving bricks are distributed in multiple rings around the tower base. The bottom surfaces of each pair of adjacent paving bricks are movably connected to drainage grooves. The top surface of each paving brick is provided with a horizontal through groove. The pressing brick is engaged with multiple collinear horizontal through grooves. The horizontal through grooves and the pressing brick are vertically provided with a first coaxial mounting hole. An anchor rod is inserted into the stable soil layer below the paving brick through the first mounting hole.
[0007] Multiple second mounting holes are provided in the drainage channel at intervals along the length of the drainage channel. A water supply pipe is inserted through the second mounting hole and embedded in the stable soil and rock layer below the pressing brick. The bottom end of the water supply pipe has a split structure and is obliquely embedded in the stable soil and rock layer. The split structure forms a liquid outlet.
[0008] To better achieve the above technical solution, optionally, the bottom surface of the paving brick is provided with an installation groove, the drainage groove is a U-shaped structure, and the side wall of the upper edge of the drainage groove is fitted with the side wall of the installation groove with a clearance.
[0009] Optionally, the top surface of the paving brick is provided with multiple planting holes, and the walls of the planting holes are provided with water-locking sleeves.
[0010] Optionally, the bottom outer wall of the water supply pipe is provided with water passage holes at intervals, and the inner wall of the water passage holes is connected with an extension plate, the middle part of which is embedded in the stable soil layer.
[0011] Optionally, the water supply pipe is filled with a water-retaining material.
[0012] Optionally, the upper end of the water supply pipe is provided with a filter cap located in the drainage trough.
[0013] Optionally, the water supply pipe may be detachably equipped with a trapezoidal cover that covers the filter cap. The side wall of the trapezoidal cover located on the upper side in the direction of water flow is a sludge intercepting plate, and the side wall of the trapezoidal cover located on the lower side in the direction of water flow is a water permeable plate. The water permeable plate is evenly distributed with water permeable holes.
[0014] Optionally, the top surface of the paving brick has anti-slip texture.
[0015] The beneficial effects of this invention are:
[0016] This invention discloses a protective structure for power tower foundations. Road pavers are embedded within the soil and rock layer, secured using brick clamps and anchor bolts. Simultaneously, drainage channels are movably connected to the bottom surfaces of adjacent road pavers, ensuring the soil and rock layer surface is covered by both the road pavers and drainage channels. This prevents rainwater from eroding the soil and rock layer and prevents vegetation from lifting the road pavers, thus maintaining soil and water conservation. The drainage channels guide rainwater out, and a water supply pipe within the channels allows some rainwater to enter deeper soil and rock layers, reducing water waste. The movable connection between the road pavers and drainage channels prevents interference from thermal expansion and contraction. This power tower foundation protection structure is simple, easy to construct, and effectively solves the problems of soil and water conservation and stability maintenance for tower foundations.
[0017] The present invention provides a protective structure for the base of an electric tower. The inner rod pushes against the T-shaped rod, causing the round end of the T-shaped rod to extend out of the T-shaped through hole and push the extension plate to unfold, thereby opening the water passage hole. The extension plate is embedded in the stable soil layer, which not only increases the water conductivity between the water supply pipe and the soil layer, but also increases the connection strength between the water supply pipe and the soil layer.
[0018] The present invention provides a protective structure for the base of an electric tower. By setting a trapezoidal cover, the area around the water filter cap can be prevented from being blocked, so that rainwater flowing through the trapezoidal cover will inevitably replenish the water supply to the water supply pipe.

[0028] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.
[0029] Please see Figures 1 to 5 This invention discloses a protective structure for a power tower base, including a power tower 10, a tower base 20, and a protective structure. The tower base 20 is made of concrete, the power tower 10 is vertically installed at the top of the tower base 20, and the protective structure is arranged around the periphery of the tower base 20.
[0030] like Figure 1 and Figure 5 As shown, the protective structure includes paving bricks 31, pressing bricks 32, drainage channels 33, anchor bolts 34, and water supply pipes 35. The paving bricks 31 are distributed in multiple rings around the tower base 20. The paving bricks 31 are embedded in the soil and rock layer around the tower base 20. The bottom surface of each pair of adjacent paving bricks 31 is movably connected to the drainage channel 33. The top surface of each paving brick 31 is provided with a horizontal through groove 311. The pressing bricks 32 are engaged with multiple collinear horizontal through grooves 311. The horizontal through grooves 311 and the pressing bricks 32 are vertically provided with a coaxial first mounting hole 312. The first mounting hole 312 is provided with an anchor bolt 34 embedded in the stable soil and rock layer below the paving bricks 31, so that the paving bricks 31, pressing bricks 32, anchor bolts 34, and soil and rock layer are combined to form a stable structure.
[0031] In the embodiments of this application, the specifications of the paving brick 31 are 400mm*400mm, the length of the pressing brick 32 is preferably 17000m, one pressing brick 32 can be used with four paving bricks 31, the width of the horizontal through groove 311 is preferably 50mm-100mm, and the depth is preferably 10mm-20mm.
[0032] like Figure 2 As shown, multiple second installation holes are spaced apart along the length of the drainage channel 33. Each second installation hole is fitted with a water supply pipe 35 embedded in the stable soil layer below the pressure brick 32. The bottom end of the water supply pipe 35 has a split structure and is obliquely embedded in the stable soil layer, forming a liquid outlet.
[0033] This invention discloses a protective structure for a power tower foundation. Road pavers 31 are embedded within the soil and rock layer. The road pavers 31 are fixed using pressing bricks 32 and anchor rods 34. Simultaneously, drainage channels 33 are movably connected to the bottom surfaces of adjacent road pavers 31. The soil and rock layer surface surrounding the tower foundation 20 is covered by the road pavers 31 and drainage channels 33, preventing rainwater from eroding the soil and rock layer and preventing vegetation from lifting the road pavers 31, thus providing water and soil retention. The drainage channels 33 guide rainwater out, and a water supply pipe 35 is installed within the drainage channels 33, allowing some rainwater to enter deeper soil and rock layers, reducing rainwater waste. The movable connection between the road pavers 31 and the drainage channels 33 prevents mutual interference during thermal expansion and contraction. This power tower foundation protection structure is simple, easy to construct, and effectively solves the problems of water and soil retention and maintenance stability of the tower foundation 20.
[0034] like Figure 5 As shown in the embodiment of this application, the bottom surface of the paving brick 31 is provided with an installation groove 313, and the drainage groove 33 is a U-shaped structure. The side wall of the upper edge of the drainage groove 33 is fitted with the side wall of the installation groove 313 with a gap. The gap formed between the drainage groove 33 and the installation groove 313 can serve as an expansion joint, providing expansion and contraction space for the drainage groove 33 and the installation groove 313 when they expand thermally.
[0035] In the embodiments of this application, a plurality of planting holes 314 are provided through the top surface of the paving brick 31. The hole wall of the planting hole 314 is provided with a water-locking sleeve. Flowers, grasses and trees can be planted through the planting hole 314 to achieve the purpose of locking in water and keeping moist. The water-locking sleeve can limit the excessive growth of flowers, grasses and trees.
[0036] In the embodiments of this application, the top surface of the paving brick 31 has anti-slip texture 315, which includes raised dots and stripes. The anti-slip texture 315 can increase the anti-slip properties of the surface of the paving brick 31.
[0037] In the embodiments of this application, the bottom outer wall of the water supply pipe 35 is provided with a plurality of water passage holes 351 spaced apart. The inner side of the water passage hole 351 is provided with an extension piece 352. The middle part of the extension piece 352 is embedded in the stable rock and soil layer. When the water supply pipe 35 is installed in the rock and soil layer, the extension piece 352 is sealed on the water passage hole 351. When the water supply pipe 35 is fixed in the rock and soil layer, the extension piece 352 is unfolded using an expansion tool, thereby opening the water passage hole 351. Rainwater in the water supply pipe 35 permeates into the rock and soil layer through the water passage hole 351.
[0038] like Figure 4 As shown, the extension tool includes an outer tube 41, a T-shaped rod 42, a spring 43, a first retaining ring 44, a second retaining ring 45, and an inner rod 46. The bottom of the outer tube 41 has a radially open T-shaped through hole 411, smaller on the outside and larger on the inside. The end of the larger diameter section of the T-shaped rod 42 is rounded, and the end of the smaller diameter section is inclined. A first retaining ring 44 is fixed near the end of the smaller diameter section of the larger diameter section of the T-shaped through hole. The larger diameter section of the T-shaped rod 42 slides with the smaller diameter section of the T-shaped through hole 411. The smaller diameter section of the T-shaped rod 42 moves through the first retaining ring 44 and is fitted with a second retaining ring 45. A spring 43 is fitted between the first retaining ring 44 and the second retaining ring 45 on the smaller diameter section of the T-shaped rod 42. 3 is fixedly connected to the first retaining ring 44 and the second retaining ring respectively. When the inner rod 46 and the outer tube 41 are independent of each other, the spring 43 is in the reset state. The large diameter section of the T-shaped rod 42 extends into the small diameter section of the T-shaped through hole 411 and the small diameter section of the T-shaped rod 42 extends into the outer tube 41. When the T-shaped rod 42 is inserted into the bottom of the outer tube 41, the inner rod 46 pushes the T-shaped rod 42 to move radially outward along the T-shaped through hole 441, so that the large diameter section of the T-shaped rod 42 extends out of the T-shaped through hole 411 and pushes the extension piece 352 to unfold. The water passage hole 351 opens and the extension piece 352 is embedded in the stable soil layer. This not only increases the water conductivity between the water supply pipe 35 and the soil layer, but also increases the connection strength between the water supply pipe 35 and the soil layer.
[0039] In the embodiments of this application, the water supply pipe 35 is filled with a water-retaining material, which includes fine sand and absorbent cotton thread. The fine sand has a filtering function, and the absorbent cotton thread can lock in water.
[0040] In the embodiments of this application, the upper end of the water supply pipe 35 is covered with a filter cap 353 located in the drainage groove 33, and the filter cap 353 covers the upper end of the water supply pipe 35.
[0041] In the embodiments of this application, a trapezoidal cover 354 covering the filter cap 353 is detachably provided inside the water supply pipe 35. The side wall of the trapezoidal cover 354 located on the upper side in the direction of water flow is a dirt intercepting plate 3541, and the side wall of the trapezoidal cover 354 located on the lower side in the direction of water flow is a water permeable plate 3542. The water permeable plate 3542 is evenly distributed with water permeable holes. When there is less rain, the dirt intercepting plate 3541 can intercept some impurities, allowing cleaner rainwater to enter the water supply pipe 35 through the water permeable holes. When there is more rain, the impurities intercepted by the trapezoidal cover 354 are washed away by the rainwater, and similarly, cleaner rainwater enters the water supply pipe 35 through the water permeable holes. The trapezoidal cover 354 can prevent the area around the filter cap 353 from being blocked, so that when the rainwater flows through the trapezoidal cover 354, it will inevitably replenish the water supply pipe 35.
[0042] The technical solution of the present invention has been described in detail above with reference to specific embodiments. The specific embodiments described are used to help understand the concept of the present invention. Derivations and modifications made by those skilled in the art based on the specific embodiments of the present invention also fall within the scope of protection of the present invention.
