Description

Technical Field

[0001] The invention belongs to the technical field of inserted tower leg reinforcement of a power transmission angle steel tower, and in particular relates to an inserted tower leg reinforcement method, system, medium and equipment for a power transmission angle steel tower. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] At present, the connection methods of the upper tower structure and the foundation of the transmission angle steel tower mainly include connecting the upper tower structure through the tower foot plate with the anchor bolts and directly inserting the angle steel (steel pipe) into the foundation column. The slope of the angle steel of the inserted foundation is consistent with the slope of the main material of the tower leg, which makes the foundation force transmission more direct and saves the amount of concrete and steel. Therefore, this foundation has been promoted and applied. However, compared with the tower foot plate type anchor bolt connection foundation, the inserted foundation does not have the tower foot bottom plate structure on the top surface of the foundation, and the bearing cross-sectional area at the bottom of the foundation is small. When encountering extreme wind conditions, the top surface of the foundation is subjected to the greatest force, and the inserted angle steel becomes a weak point of force, and the overload resistance capacity is relatively low. In the current situation of frequent extreme weather, it is easy to cause damage to the tower legs, and even cause the entire tower to overturn in severe cases.

[0004] In order to solve the problem of low overload resistance of directly inserted foundation, the existing technology uses the following measures to strengthen the transmission angle steel tower: perform finite element structural strength calculation based on the transmission tower-line tower coupling model to determine the weak parts of the structure, and then determine the reinforcement scheme based on the preset stress requirements and the weak parts of the structure. However, this scheme has the following problems:

[0005] (1) Only the current stress condition of the transmission angle steel tower directly inserted into the foundation column is considered, without considering the corrosion condition of the transmission angle steel tower itself, the surrounding acid-base distribution information and the influence of future weather on the stress of the transmission angle steel tower. This may affect the reinforcement effect of the inserted tower legs and fail to meet the requirements of resisting extreme weather.

[0006] (2) To determine the weak parts of the structure by finite element analysis of the transmission tower-line tower coupling model, the entire model needs to be discretized to generate a large number of units and nodes, resulting in a large amount of calculation and a long calculation time. In addition, in specific applications, the finite element analysis unit and mesh density are completely dependent on user experience, which affects the reinforcement effect of the inserted tower leg. Summary of the invention

[0007] In order to solve the above technical problems, the present invention provides a method, system, medium and equipment for reinforcing the inserted tower legs of a transmission angle steel tower, which can quickly and accurately determine the reinforcement plan of the inserted tower legs and ensure the reinforcement effect of the inserted tower legs.

[0008] In order to achieve the above object, the present invention adopts the following technical solution:

[0023] Based on the stress cloud diagram after reinforcement, determine the stress at the weak position after reinforcement;

[0024] The stress at the weak position after reinforcement is compared with the preset stress threshold. If the former is less than the latter, the specification of the internally attached angle steel is adjusted until the stress at the weak position after reinforcement is greater than or equal to the preset stress threshold.

[0025] As an implementation mode, the corrosion degree is characterized by the corrosion area.

[0037] When the predicted bearing capacity reduction is greater than the maximum value of the preset bearing capacity reduction range, the reinforcement scheme is to globally reinforce the inserted tower leg by using internally attached angle steel extending into the inserted tower leg foundation.

Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0057] Figure 1 FIG. 1 is a flow chart of a method for reinforcing a transmission angle steel tower inserting tower leg according to an embodiment of the present invention. Figure 1 The method for reinforcing the inserted tower legs of a power transmission angle steel tower in the embodiment shown may include:

[0058] S101, obtaining the corrosion position and corrosion degree information of the transmission angle steel tower, the acidity and alkalinity distribution information of the surrounding environment, the weather information in the future set time period and the initial stress cloud map, and forming the influencing factor data;

[0059] S102, based on the influencing factor data and the pre-trained deep learning model, predicting the weakening amount and weak position of the inserted tower leg of the transmission angle steel tower within a future set time period;

[0060] S103, comparing the predicted weakening amount of the bearing capacity of the inserted tower leg of the transmission angle steel tower with a preset weakening amount range of the bearing capacity, and determining a reinforcement scheme for the inserted tower leg according to the comparison result.

[0061] When the predicted weakening of the bearing capacity is within the preset weakening range of the bearing capacity, the reinforcement scheme is to use internally attached angle steel for local reinforcement at the predicted weak position;

[0062] When the predicted bearing capacity reduction is greater than the maximum value of the preset bearing capacity reduction range, the reinforcement scheme is to globally reinforce the inserted tower leg by using internally attached angle steel extending into the inserted tower leg foundation.

[0063] This embodiment comprehensively considers the influencing factor data such as the corrosion position and corrosion degree information of the transmission angle steel tower, the acid-base distribution information of the surrounding environment, the weather information in the future set time period and the initial stress cloud map, and uses these influencing factor data to obtain the bearing capacity weakening amount and weak position of the inserted tower leg of the transmission angle steel tower in the future set time period, and then determines the reinforcement scheme of the inserted tower leg by comparing the result with the preset bearing capacity weakening amount range, thereby improving the accuracy of the reinforcement scheme of the inserted tower leg and ensuring the reinforcement effect of the inserted tower leg;

[0064] This embodiment uses a pre-trained deep learning model to predict the bearing capacity reduction and weak position of the inserted tower leg of the transmission angle steel tower within a future set time period, which solves the defects of large calculation amount, long calculation time and reliance on user experience in finite element analysis, and improves the speed and accuracy of generating reinforcement schemes for such inserted tower legs.

[0065] In step S101, the corrosion position of the transmission angle steel tower is characterized by coordinates in a pre-constructed three-dimensional coordinate system; wherein the three-dimensional coordinate system is a three-dimensional coordinate system constructed with the contact point between any inserted tower leg of the transmission angle steel tower and the ground as the origin.

[0066] In one or more embodiments, the corrosion degree is characterized by the corrosion area.

[0067] It should be noted here that the corrosion area can be obtained by using image processing algorithms or phased array technology, and those skilled in the art can make specific settings according to actual conditions.

[0068] In this embodiment, the ambient environment acidity and alkalinity distribution information includes:

[0069] Soil acidity and alkalinity information within a preset range from each plug-in tower leg, centered on each plug-in tower leg;

[0070] Atmospheric acid-base information in the three-dimensional space of the entire transmission angle steel tower.

[0071] Specifically, a three-dimensional coordinate system identical to that characterizing the corrosion position of the transmission angle steel tower is constructed, and a three-dimensional grid space of the transmission angle steel tower with a preset grid size is constructed in the three-dimensional coordinate system, thereby determining the soil acid-base information of the ground contacted by the transmission angle steel tower and the atmospheric acid-base information of the entire transmission angle steel tower in the three-dimensional grid space.

[0072] In this embodiment, the weather information includes wind speed and rainfall.

[0073] It should be noted here that weather information may include temperature and other information in addition to wind speed and rainfall.

[0074] In this embodiment, the construction process of the initial stress cloud map is:

[0075] Obtain initial stress monitoring data of the entire transmission angle steel tower;

[0076] Based on the structural parameters of the transmission angle steel tower and the initial stress monitoring data, the initial stress cloud map was constructed.

[0077] In step S102, the deep learning model may adopt a neural network model such as LSTM (Long Short-Term Memory Network), and those skilled in the art may make a specific selection based on actual conditions.

[0078] In the process of training the deep learning model, the influencing factor data is used as input, and the bearing capacity reduction and weak position of the inserted tower legs of the transmission angle steel tower within a set time period in the future are output to form a training sample.

[0079] It should be noted here that the number of weak positions is at least one, and the weak positions adopt the same three-dimensional coordinate system as that used to characterize the corrosion positions of the transmission angle steel tower.

[0080] The weakening amount of the bearing capacity of the inserted tower leg of the transmission angle steel tower within the future set time period is the same as the stress unit represented by each point in the initial stress cloud diagram.

[0081] In step S103, the range of the bearing capacity reduction amount can be specifically set according to the actual situation, for example, set to [ a , b ]; When the predicted weakening of the bearing capacity x In the preset bearing capacity reduction range [ a , b ], the reinforcement scheme is to use internally attached angle steel for local reinforcement at the predicted weak position;

[0082] When the predicted reduction in bearing capacity x Greater than the maximum value of the preset bearing capacity reduction range b When the inserted tower leg is used, the reinforcement scheme is to globally reinforce the inserted tower leg by using internally attached angle steel extending into the inserted tower leg foundation.

[0083] When the predicted reduction in bearing capacity x Less than the minimum value of the preset bearing capacity reduction range a No reinforcement is performed.

[0084] In the specific implementation process, the specifications of the internally attached angle steels for local reinforcement and global reinforcement are determined by the predicted weakening of the bearing capacity.

[0085] The process of determining the specifications of the internally attached angle steels for local reinforcement and global reinforcement is as follows:

[0086] According to the predicted weakening of the bearing capacity of the inserted tower legs of the transmission angle steel tower, the minimum reinforcement value and reinforcement range are determined;

[0087] The specifications of the internally attached angle steel are determined based on the minimum reinforcement value, reinforcement range and the moment of inertia of the internally attached angle steel.

[0088] In the process of determining the specifications of the internally attached angle steel, since the force on the main material of the tower leg is mainly bending stress, when the lap weld is subjected to bending moment, when the weld length is greater than the set weld length threshold, Figure 2 , torque The maximum normal bending stress caused is shown in the following formula, which shows that the length of the fillet weld has a greater effect.

[0089]

[0090] In the formula, represents the bending normal stress, MPa; represents the external bending moment acting on the joint, N·mm; Indicates the bending section modulus, mm 3 ; Indicates the size of the weld leg, mm; Indicates the weld length, mm; Indicates the allowable shear stress of the weld, MPa.

[0091] If the two overlapping parts are made of the same material and have the same wall thickness, the bending section modulus is It is twice as large as a single component, so the angle steel of the same material and specification is attached to the original main angle steel.

[0092] The following takes the global reinforcement of the inserted tower leg by using internally attached angle steel extending into the inserted tower leg foundation as an example to give a detailed description of the specific reinforcement process:

[0093] (1) Remove the concrete at the base of the tower leg angle steel and expose the angle steel. Figure 3As shown, the depth is not less than 150mm, so that the inner angle steel can smoothly fall into the 150mm deep concrete foundation, and then grind the concrete and rust, debris, etc. on the surface of the angle steel. If the zinc layer on the surface of the angle steel is damaged, it should be polished to reveal the metallic luster and then zinc spraying for corrosion protection.

[0094] (2) The length of the reinforced angle steel is 150 mm from the lower section of the angle steel clamped on the inner side of the original tower foot main material to the concrete. Measure the bolt range on the tower leg main material and use the plasma method to process square grooves on the reinforced main material, such as Figure 4 shown.

[0095] (3) For tower legs with main materials and diagonal materials connected by fixing plates, steel plates of corresponding sizes shall be processed according to the exposed size of the steel plates fixing the diagonal materials, and welded to the steel plates fixing the diagonal materials. One side shall be butted against the edge of the side width of the main material of the tower leg, and the other corners shall be connected to the steel plate.

[0096] (4) The cutting surface of plasma processing should reserve grinding allowance. After cutting, the contaminated layer should be polished to expose the metallic luster, and then the cutting surface and its surrounding area should be cold-sprayed with zinc for corrosion protection.

[0097] (5) The internal additional fixing angle steel and the clamping angle steel are connected by butt welds. All butt weld sections are processed into "V"-shaped grooves with an angle of 60°, a butt gap c of 2-3mm, and a blunt edge p of 1mm-2mm.

[0098] (6) The slotted reinforcement angle steel is one specification smaller than the original main angle steel, and the upper and lower overlap lengths are not less than 100mm.

[0099] (7) The inner angle steel is superimposed with the outer angle steel at a right angle. The outer right angle should be back-shoveled. The back-shovel arc is basically the same as the inner angle arc of the angle steel. The back-shovel depth is 2mm-3mm. Figure 5 and Figure 6 The back of the shovel should be treated with zinc spraying for corrosion protection. Figure 5 In the figure, L is the overlap length with the external angle steel; L1 is the back length of the shovel. Figure 6 In the figure, R is the inner arc radius of the outer angle steel, and R1 is the outer arc radius of the inner angle steel. Figure 5 The length and Figure 6 The unit of arc radius is mm.

[0100] (8) Welding reinforcement method is adopted, welding process parameters: welding method is manual arc welding (SMAW), welding material is E5003, specification is Φ3.2mm, welding current is: 110A-170A. The welding rod should be kept in a dry container. When the ambient humidity is high, it should be dried according to the requirements of the welding rod manual.

[0101] (9) The weld surface is not allowed to have cracks, lack of fusion, pores, slag inclusions, undercuts and other exposed defects. The weld fillet height is 0.7 times that of thin-walled steel.

[0102] (10) Anti-corrosion treatment: After the reinforcement of the main material is completed, the weld surface and the burned hot-dip galvanized layer should be polished to reveal the metallic luster, and then the steel surface in the entire reinforcement range should be cold-sprayed with zinc for anti-corrosion. Cold-dip galvanizing anti-corrosion is carried out by spraying. The nozzle and the component must be kept at an appropriate distance, and the spray gun should swing evenly. The number of spraying times should be no less than 3 times. The average thickness of the zinc layer should not be less than 120μm, and the minimum value should not be less than 110μm. The zinc coating should be uniform and flat, without missing coating, sagging, impurities, cracks, peeling, blistering, shrinkage, convexity and concaveness, etc.

[0103] (11) Sealing: In order to form a closed space between the reinforced angle steel and the original leg angle steel, silicone neutral structural weather-resistant adhesive is used to seal all the gaps after reinforcement. The sealing surface must be flat and smooth, the sealing angle height must be consistent with the fillet weld, and the sealing angle height at the overlap must not be less than the end face of the sealing gap.

[0104] (12) Foundation repair: Grind the foundation surface to a rough surface and clean the surface impurities. Make a standard mold close to and fasten it to the original foundation column surface. There should be no obvious deformation after pouring concrete. Mix cement, sand and epoxy resin according to the proportion of C50 grade concrete, pour them into the mold and compact them, and smooth the surface. The surface of the concrete mortar foundation should not have defects such as cracks, pores, excessive sand holes and honeycombs. The height of the restored damaged foundation surface should be 20mm greater than the original foundation surface.

[0105] (13) Water-proof layer: Prepare epoxy coal tar according to the required proportion and stir evenly, and apply epoxy coal tar within 200mm from the foundation surface to the inner clamping angle steel. The end surface of the epoxy coal tar layer is basically a straight line, and there should be no missing coating, pores, severe sagging, etc. on the surface. The thickness of each coating layer should be no less than 80μm.

[0106] This embodiment uses welding technology to reinforce the inserted tower legs of the transmission tower angle steel, which effectively improves the bearing capacity of the tower foot of the transmission tower; the welding technology is used to reinforce the angle steel and the original angle steel for metallurgical combination, which realizes the integrated improvement effect of the strength of the transmission tower. The optimized welding process is easy to implement, does not require preheating before welding and heat treatment after welding, and effectively guarantees the welding quality at the same time, which is suitable for reinforcement of field transmission towers; it is easy to implement, easy to operate, and has reliable effects.

[0107] In one or more embodiments, after determining the reinforcement scheme of the inserted tower leg, the method further includes:

[0108] Obtain stress monitoring data of the entire transmission angle steel tower after implementing the reinforcement scheme of inserted tower legs;

[0109] Based on the structural parameters and stress monitoring data of the transmission angle steel tower, the stress cloud map after reinforcement is constructed;

[0110] Based on the stress cloud diagram after reinforcement, determine the stress at the weak position after reinforcement;

[0111] The stress at the weak position after reinforcement is compared with the preset stress threshold. If the former is less than the latter, the specification of the internally attached angle steel is adjusted until the stress at the weak position after reinforcement is greater than or equal to the preset stress threshold.
