Description

Technical Field

[0001] The present invention relates to the technical field of water pipeline layout, and in particular to a water pipeline layout method for a pipeline water delivery system. Background Art

[0002] As one of the five means of preventing and controlling mine water hazards, mine drainage technology is diverse and widely used. Using specific drainage technology based on specific problems can often achieve good results. However, when a single drainage technology is used for drainage in a large area, the drainage effect will be greatly reduced due to the complexity of the water storage medium.

[0003] Usually a pipeline water supply system is used for drainage. The existing water supply system usually allows water to enter the drainage tunnel through the drainage hole, and then flow through the underground drainage tunnel to the water tank in the parking lot at the bottom of the well, and then be transported to the drainage pipe through a centrifugal pump installed in the water tank, and then discharged to the surface pipeline system through two direct discharge wells. After converging on the ground, it is uniformly transported to the outside of the curtain. The drainage water is transported by two branch pipelines, which merge on the surface to form a main pipeline. The drainage water is transported by two stages of pressurization. The first stage of pressurization is located in the water tank pump room, and the second stage of pressurization is located near the direct discharge hole section. In the above-mentioned water supply system, the surface convergence forms a main pipeline that needs to cross complex terrain until it is discharged outside the curtain;

[0004] However, the existing pipeline layout method cannot meet the changing requirements of pipeline layout in the pipeline water supply system, and its economy, safety and compatibility need to be improved. Therefore, a water supply pipeline layout method for the pipeline water supply system is designed.

[0005] In order to solve the above defects, a technical solution is now provided. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that the existing pipeline layout method cannot meet the changing requirements of pipeline layout in the pipeline water supply system, and its economy, safety and compatibility need to be improved, and to propose a water supply pipeline layout method for the pipeline water supply system.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A method for arranging water delivery pipelines for a pipeline water delivery system comprises the following steps:

[0009] S1: First, the water delivery demand, water delivery volume and water delivery distance of the water delivery pipeline in the pipeline water delivery system are collected and measured;

[0010] S2: Determine the flow rate at the outlet of the water delivery pipeline according to the water delivery demand, and determine the diameter of the water delivery pipe in the pipeline layout according to the flow rate at the outlet; after determining the diameter of the water delivery pipe, calculate the flow rate at the end of the outlet, and select the power of the water supply pump according to the flow rate;

[0011] S3: arranging the path of the water delivery pipeline using the obtained diameter, flow rate, flow velocity and water supply pump power of the water delivery pipeline in combination with the path arrangement rule;

[0012] The path layout rules include:

[0013] The planned path should be as straight as possible, with minimal bends, to ensure good hydraulic conditions, and the pipeline should be as short as possible, economical and scientific;

[0014] As close to the wall as possible to facilitate construction, operation and later maintenance and repair;

[0015] The surface pipeline route should be fully connected with the construction department, planning unit, ownership unit, land management department, etc., and meet the requirements of relevant units as much as possible;

[0016] Try to avoid existing optical cables, electric cables and other facilities to occupy less farmland;

[0017] The path layout rules also include the following steps:

[0018] S301: When an obstacle point is encountered, the size, area, position and height of the obstacle point are collected, and three-dimensional modeling is performed using the collected data. The starting and ending points of the pipeline detour arrangement are selected in the established three-dimensional model of the obstacle point, and multiple nodes are established around the three-dimensional model. Several nodes are connected from the initial point of the pipeline detour arrangement to the end point of the pipeline detour arrangement. Each time a nearest node is connected, the connecting node updates the nearest node in the direction of the end point of the pipeline detour arrangement, and connects to the next node, and this cycle is repeated until the end point of the pipeline detour arrangement is connected, thereby determining the shortest path connecting the initial point of the pipeline detour arrangement to the end point of the pipeline detour arrangement;

[0019] S302: Obtain the straight-line distance between the initial point of the pipeline detour arrangement and the end point of the pipeline detour arrangement and the shortest path distance connecting the initial point of the pipeline detour arrangement to the end point of the pipeline detour arrangement through three-dimensional modeling of the obstacle point, and substitute them into the formula to calculate the bend angle value;

[0020] S303: The obtained straight-line distance between the start and end points, the shortest detour distance between the start and end points and the bend angle value are calculated using a formula to obtain a discrimination value, and compared with a preset discrimination threshold. When the discrimination value is higher than the discrimination threshold, the obstacle point is handled in a through-going manner; when the discrimination value is lower than the discrimination threshold, the obstacle point is handled in a detour manner;

[0021] S4: After completing the route planning of the water pipeline, determine the pipeline material;

[0022] S5: After determining the appropriate material for the pipeline, an interconnected search is performed to retrieve different material information for display.

[0023] Furthermore, the specific process of determining the pipeline material includes the following steps:

[0024] S401: After completing the route planning of the water pipeline, the determined pipe diameter, flow rate and flow velocity are calculated through a formula to obtain a basic parameter value;

[0025] S402: Count the residents within a 5-meter range perpendicular to the pipeline path, record the number of permanent residents and temporary residents among all residents, and calculate the two values ​​using a formula to obtain a noise value;

[0026] S403: After completing the route planning of the water pipeline, the number of bypass pipes used and the curvature of each bypass pipe are obtained, and the curvature of each bypass pipe is calibrated as: RW1, RW2, RW3, ... RW w ; At the same time, the number of pipe sections with height differences will be obtained, and the height difference and length of this type of pipe section will be collected, and the height difference and length of each pipe section with height difference will be calibrated as GD1, GD2, GD3, ... GD g and CD1, CD2, CD3, ...CD g ; Set RW1, RW2, RW3, ... RW w 、GD1、GD2、GD3、......GD g and CD1, CD2, CD3, ...CD g The numerical value is normalized and substituted into the formula to obtain the bending difference value;

[0027] S404: Establish triangles with the obtained base parameter values, noise shadow values ​​and bend difference values ​​respectively, and calculate the area of ​​the triangle, which is the material shadow value; establish three groups of continuous material shadow value intervals, namely the first interval, the second interval and the third interval, and compare the obtained material shadow value with the first interval, the second interval and the third interval of the three groups of continuous material shadow value intervals. When it is determined in which interval the material shadow value is located, the suitable material for the pipeline is determined; the first interval, the second interval and the third interval correspond to three different materials respectively, and the performance of the three materials is improved in turn.

[0028] Furthermore, the specific steps for conducting an Internet search and retrieving different material information for display are as follows:

[0029] When the appropriate material for the pipeline is determined, an interconnected search is performed to retrieve different material information; the material information includes the pipeline material type, merchant name, price and distance, and multiple sets of material information are compared to screen out suitable pipeline materials for display, while providing backup material information for selection; based on the selected pipeline material and the merchant's price, combined with the pipeline distance for the entire water pipeline route planning, the cost of the entire pipeline is calculated and prompted.

[0030] Furthermore, the specific steps for determining the way to bypass the obstacle point are as follows:

[0031] When dealing with obstacles by detouring, the shortest path between the initial point and the end point of the pipeline detour is captured in the three-dimensional model in the path planning of the water pipeline, and the pipeline is arranged according to this path.

[0032] Furthermore, the specific steps for determining the way to penetrate the obstacle point are as follows:

[0033] When dealing with obstacles through penetration, it is divided into through-wall laying, bracket laying and underground laying. The choice of penetration method is first determined by the type of obstacle;

[0034] When the obstacle type is a building, a wall or a fence, the through-wall paving method is selected, wherein the number of walls required to be penetrated in the building is collected, and the impact assessment inside the building is rated, and a preset value and a preset level are set. When the number of walls required to be penetrated in the building is less than the preset value and the level of the impact assessment inside the building is less than the preset level, then when the obstacle is a building, the through-wall paving method is selected;

[0035] When the obstacle type is a road, river or ditch, choose a support for laying, test the penetration length of such obstacles, and select supports with different load-bearing capacities. Calculate the total load of the object that penetrates the obstacle based on the penetration length, known pipe diameter and the weight of the fully loaded pipe of this penetration length; when selecting a support, ensure that its load-bearing capacity is greater than the object that penetrates;

[0036] When the obstacle types are railways and urban buildings with too many walls, the underground laying penetration method is selected; the underground laying penetration method is complex to construct and occupies more resources. Therefore, when underground laying and the other two penetration methods meet the requirements, the through-wall laying or bracket laying penetration method is selected for pipeline layout.

[0037] Furthermore, the water supply demand of the water pipeline is the amount of water required to be transported in the water supply system within an expected time period; the water supply volume of the water pipeline is the detection of the flow rate at the input and outlet of the pipeline; the water supply distance of the water pipeline is the distance from the water source to the delivery end of the entire water pipeline calculated after the layout of the water supply route is completed.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] (1) The present invention, when arranging the water pipeline of the water delivery system, adopts different traversing methods for different obstacle points, considers different pipeline layout factors, and selects the optimal layout method, which not only provides a reference plan for construction personnel, but also optimizes the construction steps, improves engineering efficiency, meets the requirements of variable pipeline layout in the pipeline water delivery system, and has good compatibility;

[0040] (2) After completing the pipeline layout of the optimal path for different obstacle points, the present invention selects the most suitable pipeline material according to different parameters, and uses the Internet search to recommend suitable pipeline material merchants to construction personnel, thereby reducing the search time of budget personnel and improving the construction efficiency of the entire project.

[0046] like Figure 1 As shown, a water delivery pipeline layout method for a pipeline water delivery system includes a pipeline layout system, and the pipeline step system includes a measurement module, an analysis module, a path planning module and a material selection module;

[0047] The measurement module is used to collect and measure the water supply demand, water supply volume and water supply distance of the water supply pipeline; the water supply demand of the water supply pipeline is the amount of water required to be transported in the water supply system within the expected time period; the water supply volume of the water supply pipeline is the detection of the flow rate at the input and outlet of the pipeline; the water supply distance of the water supply pipeline is the calculation of the distance from the water source to the delivery end of the entire water supply pipeline after the layout of the water supply route is completed;

[0048] The analysis module is used to receive the data measured by the measurement module, determine the flow rate at the drain outlet of the water delivery pipeline according to the water volume required to be delivered within the estimated time period, and determine the water delivery pipe diameter in the pipeline layout according to the flow rate at the drain outlet. For details, please refer to Table 1-1;

[0049] After the pipe diameter is determined, the flow rate at the end of the drain outlet can be calculated based on the preset pipe diameter, and the power of the water supply pump can be selected based on the flow rate. Please refer to Table 1-2;

[0050] Table 1-1 Relationship between pipe diameter, flow rate and flow rate

[0051] Pipe diameter(mm) Maximum flow rate (L / s) Maximum flow rate (m / s) 25 1 2.04 50 4.17 2.12 75 10 2.26 100 18.4 2.33 150 43 2.45 200 83.3 2.69 250 133.3 2.72 300 192 2.71

[0052] Table 1-2 Relationship between pipe diameter and water pump power

[0053]

[0054]

[0055] After the diameter, flow rate, flow velocity and water supply pump power of the water supply pipeline are determined, a data group consisting of a path planning signal and the diameter, flow rate, flow velocity and water supply pump power of the water supply pipeline is generated and packaged to the path planning module to plan the layout path of the water supply pipeline;

[0056] The path planning module is used to plan the path of the water pipeline. After receiving the path planning signaling, the data group is parsed to obtain the diameter of the water pipeline, and the path of the water pipeline is arranged using the path layout rules. The path layout rules include:

[0057] 1) The planned path should be as straight as possible, with minimal bends, to ensure good hydraulic conditions, and the pipeline should be as short as possible, economical and scientific;

[0058] 2) As close to the wall as possible to facilitate construction, operation and later maintenance and repair;

[0059] 3) The surface pipeline route should be fully connected with the construction department, planning unit, ownership unit, land management department, etc., and meet the requirements of relevant units as much as possible;

[0060] 4) Try to avoid existing optical cables, electrical cables and other facilities to minimize the occupation of farmland.

[0061] In the layout rules of path planning, when encountering obstacles, such as buildings, bridges or roads, two methods are used: detour or penetration. First, the size, area, position and height of the obstacle are collected, and three-dimensional modeling is performed using the collected data. The starting and ending points of the pipeline detour are selected in the established three-dimensional model of the obstacle, and multiple nodes are established around the three-dimensional model. Several nodes are connected from the initial point of the pipeline detour to the end point of the pipeline detour. Each time a nearest node is connected, the connecting node updates the nearest node in the direction of the end point of the pipeline detour, and connects to the next node, and this cycle is repeated until it is connected to the end point of the pipeline detour, thereby determining the shortest path connecting the initial point of the pipeline detour to the end point of the pipeline detour.

[0062] Through the three-dimensional modeling of the obstacle point, the straight-line distance between the initial point and the end point of the pipeline detour arrangement and the shortest path distance connecting the initial point of the pipeline detour arrangement to the end point of the pipeline detour arrangement are obtained, and the straight-line distance between the start and end points and the shortest detour distance are calibrated as CY and CR respectively; it is also used to collect the inclination angle of each two nodes in the multiple nodes passed through in the detour shortest path, and obtain multiple node bending angles, which are calibrated as WJ1, WJ2, WJ3, ... WJ n , n is the number of nodes with multiple marks, remove nodes with bending angles of 0 or abnormal nodes, and substitute into the formula: The bending angle value WQ is obtained, where the bending angle of the p node is 0 or the number of abnormal node bending angles, is the correction factor;

[0063] The obtained straight-line distance CY between the start and end points, the shortest detour distance CR between the start and end points, and the bend angle value WQ are normalized and substituted into the formula Get the discriminant value PB, where They are the preset weight coefficient and correction factor of the difference between the shortest detour distance CR of the start and end points and the straight-line distance CY of the start and end points, is the preset weight coefficient of the bend angle value; the obtained discrimination value PB is compared with the preset discrimination threshold value, and when the discrimination value is higher than the discrimination threshold value, the obstacle point is handled by penetrating; when the discrimination value PB is lower than the discrimination threshold value, the obstacle point is handled by bypassing;

[0064] When dealing with an obstacle point by detouring, the shortest path between the initial point and the end point of the pipeline detour is captured, and the pipeline is arranged according to this path;

[0065] When dealing with obstacles by penetration, it is divided into through-wall laying, bracket laying and underground laying; the selection of penetration method is first determined by the obstacle type. When the obstacle type is a building, wall or fence, through-wall laying is selected, in which the number of through-walls required for the building is collected, and the impact assessment inside the building is rated, and the preset value and preset level are set. When the number of through-walls required for the building is less than the preset value and the rating of the impact assessment inside the building is less than the preset level, then when the obstacle is a building, the through-wall laying penetration method is selected; when the obstacle type is a road, river or ditch, then Choose brackets for laying, test the penetration length of such obstacles, and select brackets with different load-bearing capacities. Calculate the total load of the object that penetrates the obstacle based on the penetration length, known pipe diameter, and the weight of the fully loaded pipe of this length. When selecting brackets, ensure that their load-bearing capacity is greater than the total load of the object that penetrates. For details, refer to Table 1-3. When the obstacle type is a railway or an urban building with too many walls, choose the underground laying penetration method. It should be noted that the underground laying penetration method is more complicated to construct. When underground laying and the other two penetration methods are reached, the penetration method of wall laying or bracket laying should be selected as much as possible for pipeline layout.

[0066] Table 1-3 Relationship between penetration distance, total load of penetration and support bearing capacity

[0067] Penetration distance Total penetration load Support load capacity 1.0-5.0m 1-10T 10-50T 5.0-10.0m 10-50T 50-100T 10.0-20.0m 50-100T 100-200T

[0068] The material selection module is used to determine the pipe material after completing the route planning of the water pipeline; the determined pipe diameter, flow rate and flow rate are calibrated as R, L and S respectively, and normalized and then entered into the formula: The basic parameter value JZ is obtained, where Ξ, Ψ, and Z are the preset weight coefficients of pipe diameter, flow rate, and flow velocity, respectively; and the residents within a horizontal range of five meters perpendicular to the pipeline path are counted, and the number of permanent residents and temporary residents among all residents is calibrated as CM and ZM, respectively, and then normalized and entered into the formula: The noise shadow value ZY is obtained, where X is the correction coefficient and GJC is the total distance of the pipeline layout; the more permanent residents CM and temporary residents ZM among all residents, the larger the noise shadow value ZY is, and the higher the noise reduction demand of the required pipeline materials is; and the number of bypass pipelines used after the path planning of the water pipeline is completed and the bending degree of each bypass pipeline are obtained, and the bending degree of each bypass pipeline is calibrated as: RW1, RW2, RW3, ... RW w , w is the number of bypass pipes used after completing the route planning of the water pipeline; at the same time, the number of pipe sections with height differences is obtained, and the height difference and length of this type of pipe section are collected, and the height difference and length of each pipe section with height difference are calibrated as GD1, GD2, GD3, ... GD g and CD1, CD2, CD3, ...CD g , g is the number of pipe sections with height difference; RW1, RW2, RW3, ... RW w 、GD1、GD2、GD3、......GD g and CD1, CD2, CD3, ...CD g Normalize the values ​​and substitute them into the formula:

[0069]

[0070] The bend difference GZ is obtained, where Φ is the correction factor. The higher the bend difference GZ, the higher the pressure resistance, wear resistance and other parameters of the required pipeline material.

[0071] The obtained basic parameter value JC, noise shadow value ZY and bend difference value GZ are used to establish triangles respectively, and the area of ​​the triangle is calculated and calibrated as CYZ, then this area CYZ is the material shadow value; after establishing three groups of continuous material shadow value intervals, namely the first interval, the second interval and the third interval, the obtained material shadow value CYZ is compared with the first interval, the second interval and the third interval of the three groups of continuous material shadow value intervals established, when determining which interval the material shadow value CYZ is located in, the first interval, the second interval and the third interval correspond to three different materials respectively, and the various performances of the three materials are successively improved, then the suitable material for this pipeline is determined;

[0072] When the appropriate material for the pipeline is determined, an Internet search is performed to retrieve different material information; the material information includes the pipeline material type, merchant name, price and distance, and multiple sets of material information are compared to screen out suitable pipeline materials for display, and provide backup material information for selection; based on the selected pipeline material and the merchant's price, combined with the pipeline distance of the entire route planning to complete the water pipeline, the cost of the entire pipeline is calculated and prompted;

[0073] The use process of the present invention:

[0074] First, the water supply demand, water supply volume and water supply distance of the water supply pipeline in the pipeline water supply system are collected and measured through the measurement module. The water supply demand of the water supply pipeline is the amount of water required to be transported in the expected time period in the water supply system; the water supply volume of the water supply pipeline is the detection of the flow rate at the input port and the drain port of the pipeline; the water supply distance of the water supply pipeline is the calculation of the distance from the water source to the end point of the entire water supply pipeline after the layout of the water supply route is completed; the analysis module is used to determine the flow at the drain port of the water supply pipeline through the water supply demand, and determine the water supply pipe diameter in the pipeline layout according to the flow at the drain port; after determining the water supply pipe diameter, calculate the flow rate at the end of the drain port, and according to The power of the water supply pump is selected according to the flow rate; the path planning module is used to arrange the path of the water supply pipeline using the pipe diameter, flow rate, flow rate and water supply pump power of the water supply pipeline in combination with the path layout rules; in the process of path layout, when encountering an obstacle point, the size, area, position and height of the obstacle point are collected, and three-dimensional modeling is performed using the collected data. The starting and ending points of the pipeline detour are selected in the established three-dimensional model of the obstacle point, and multiple nodes are established around the three-dimensional model. Several nodes are connected from the initial point of the pipeline detour to the end point of the pipeline detour. Each time a nearest node is connected, the connection node is updated to the pipeline. The nearest node in the direction of the end point of the detour arrangement is connected to the next node, and this cycle is repeated until it is connected to the end point of the pipeline detour arrangement, thereby determining the shortest path connecting the initial point of the pipeline detour arrangement to the end point of the pipeline detour arrangement; the straight-line distance between the initial point of the pipeline detour arrangement and the end point of the pipeline detour arrangement and the obtained shortest path distance connecting the initial point of the pipeline detour arrangement to the end point of the pipeline detour arrangement are obtained through the three-dimensional modeling of the obstacle point, and are substituted into the formula to calculate the bend angle value; the obtained start-end point straight-line distance, the shortest detour distance between the start-end points and the bend angle value are calculated using the formula to obtain the discrimination value, and compared with the preset discrimination threshold The values ​​are compared.

The choice of penetration method is first determined by the type of obstacle; When the obstacle type is a building, a wall or a fence, the through-wall paving method is selected, wherein the number of walls required to be penetrated in the building is collected, and the impact assessment inside the building is rated, and a preset value and a preset level are set. When the number of walls required to be penetrated in the building is less than the preset value and the level of the impact assessment inside the building is less than the preset level, then when the obstacle is a building, the through-wall paving method is selected; When the obstacle type is a road, river or ditch, choose a support for laying, test the penetration length of such obstacles, and select supports with different load-bearing capacities. Calculate the total load of the penetration object based on the penetration length, known pipe diameter and the weight of the fully loaded pipe of this penetration length; when selecting a support, ensure that its load-bearing capacity is greater than the total load of the penetration object; When the obstacle types are railways and urban buildings with too many walls, the underground laying penetration method is selected; the underground laying penetration method is complex to construct and occupies more resources. Therefore, when underground laying and the other two penetration methods meet the requirements, the through-wall laying or bracket laying penetration method is selected for pipeline layout.
