Abstract
Description
Background Art
[0002] With the development of the national economy, the routes that can be selected for long-distance pipelines are often unique due to planning and terrain restrictions. It has become a trend for long-distance pipeline construction to use existing tunnels to lay new pipelines, or to consider reserving new tunnels when building new ones. Reusing the original tunnels to lay new pipelines can solve the problem of route uniqueness, and can reduce the damage to surface vegetation, greatly reduce the damage to surface vegetation caused by long-distance pipeline construction, and protect the ecological environment. At the same time, reusing the original tunnel sections to lay new pipelines, without the need to build new tunnels, can greatly save the construction period of long-distance pipeline construction, and correspondingly save engineering investment. Therefore, tunnel reuse has the advantages of saving engineering construction period and engineering investment.
[0003] Since there is no evaluation method for tunnel reuse in China at present, with the development of domestic long-distance pipeline construction, a scientific and complete tunnel reuse evaluation system is urgently needed to guide the implementation of tunnel reuse in future domestic long-distance pipeline construction. Therefore, it is necessary to carry out relevant research on tunnel reuse and establish a tunnel reuse evaluation method. Summary of the invention

[0032] Figure 2 The present invention is a structural framework diagram of an electronic device. DETAILED DESCRIPTION
[0033] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.
[0034] like Figure 1 As shown, a method for determining the reuse of an in-service pipeline according to an embodiment of the present invention includes the following steps:
[0035] S1, dividing the pipeline to be determined in service into multiple pipe sections, and collecting basic evaluation parameters corresponding to each pipe section;
[0036] S2, by using a preset status evaluation system, determine the indicator score corresponding to each indicator in the basic evaluation parameters in any pipe section, and determine the reuse score corresponding to the pipe section based on all indicator scores;
[0037] S3, judging the corresponding reuse grades of all pipe segments according to the reuse score corresponding to each pipe segment, and re-dividing the pipe segments whose reuse grades do not meet the preset conditions to obtain multiple sub-pipe segments, and repeatedly executing S1 and S2 with the multiple sub-pipe segments as the multiple pipe segments in S1 until the length of the sub-pipe segment is less than the preset length, and judging whether the in-service pipeline to be determined can be reused according to the reuse grade corresponding to each pipe segment.
[0038] The beneficial effects of the method for determining the reuse of an in-service pipeline provided by the present invention are as follows:
[0039] By classifying the in-service pipelines to be determined, the accuracy of subsequent reuse scores can be improved. At the same time, determining the reuse level based on the reuse score is more targeted and can more accurately determine whether the in-service pipelines can be reused.
[0040] S1, divide the pipeline to be determined in service into multiple sections, and collect the basic evaluation parameters corresponding to each section. Among them:
[0041] The division principle can be: divide the tunnel target evaluation section into sections of 100m, and sections less than 100m are regarded as a separate section.
[0042] Basic evaluation parameters include but are not limited to: (1) Karst: When there is no cave in the target section, the radius in the table is filled with "0" and the distance is filled with "10", indicating that there is no karst influence; when there are multiple caves, the data of the cave closest to the tunnel is taken as the indicator data; when multiple caves are at the same distance from the tunnel, the radius and distance of the cave with the largest radius are taken as the indicator data; when caves exist in more than two target evaluation sections, the cave data are assigned to all target sections.
[0043] (2) Fault crushing zone: When there is no fault crushing zone in the target segment, the fault dip and crushing zone width in the table are filled with "0", indicating that there is no influence of the fault crushing zone; when there is a fault crushing zone, the fault dip and crushing zone width of the fault crushing zone are used as indicator data; when the fault crushing zone exists in two or more target segments, the fault dip of all target segments adopts the same value, and the crushing zone width is the intersection width of the crushing zone and each target segment.
[0044] (3) Lining cracks: When there are multiple cracks in the target section, the crack with the largest depth ratio, the crack with the largest width, and the crack with the longest length are used as the index data of the lining cracks. When a lining crack spans two or more target sections, the crack data of all target sections spanned by the crack are used to compare with the cracks in the current section to select parameter data.
[0045] (4) Water leakage: The number of water seepage points in the target section is used as the basic data of water leakage in that section. When the water leakage area is large and spans two or more target sections, first determine whether the water leakage is point-like or surface-like. If the water leakage is point-like, the number of water leakage points in the section where the water leakage point is located is increased by 1. If the water leakage is surface-like, the number of water seepage points recorded in all the sections involved is increased by 1.
[0046] (5) Strength degradation: When there are multiple strength detection sections in the target section, the minimum ratio of actual strength to design strength is taken as the basic data for strength degradation.
[0047] (6) Insufficient lining thickness: When there are multiple insufficient lining thickness locations in the target tunnel section survey line, the minimum ratio of actual thickness to design thickness is taken as the basic data for insufficient lining thickness.
[0048] (7) Cavity behind the primary branch: When there are two or more cavities, the data corresponding to the cavity with the largest circumferential length, the largest radial depth, and the largest longitudinal length are used as the data of the segment; when the cavity exists in two or more target segments, it is divided according to its contact with each target segment, and the cavity in each segment is regarded as an independent single cavity, and the data is determined according to the above selection principles.
[0049] (8) Section intrusion limit: When there are multiple section intrusion limits in the target section, the one with the largest intrusion limit is taken as the section intrusion limit data.
[0050] (9) Floor uplift: When there are multiple floor uplift locations in the target section, the location with the largest uplift amount is taken as the floor uplift data.
[0051] (10) Quality inspection: The inspection data of condition level is derived from the technical condition score of the tunnel civil structure determined in the most recent tunnel inspection report. Since a tunnel has only one technical condition score of the civil structure, this score is used as the basic data for quality inspection of all target sections.
[0052] (11) Disease control: If disease control is carried out in the target area, the corresponding score is 100; if disease control is not carried out, the corresponding score is the condition grade score.
[0053] S2, through the preset status evaluation system, determine the indicator score corresponding to each indicator in the basic evaluation parameters in any pipe section, and determine the reuse score corresponding to the pipe section based on all indicator scores. Among them:
[0054] The preset status evaluation system is as follows: by considering the indicator construction principles, the direct impact on the tunnel structure, the weight of the evaluation indicators and the determinability of the standards, the indicators at all levels are determined. The indicators include: 17 third-level indicators, 11 second-level indicators, and 3 first-level indicators.
[0055] The three first-level indicators include: external environment, entity structure, and operation and maintenance;
[0056] The 11 secondary indicators include: karst, fault fracture zone, lining cracks, water leakage, strength degradation, insufficient lining thickness, voids behind primary support, section intrusion, floor uplift, quality inspection, and disease control;
[0057] The 17 third-level indicators include: pipeline radius, distance, fault inclination, broken zone width, length, width, depth ratio, number of penetration points, residual degree, thinning ratio, circumferential length, radial depth, longitudinal length, intrusion limit, heave amount, condition level, and maintenance and reinforcement.
[0058] The process of determining the reuse score corresponding to the pipe section based on all indicator scores is as follows:

[0060]
[0061]
[0062] In the formula: x1 is the radius of the cave (m); y1 is the score of the radius of the cave; x2 is the distance between the cave and the tunnel (m); y2 is the score of the distance between the cave and the tunnel.
[0063] 2. Fault dip and fracture zone width scoring:

[0066] In the formula: x3—fault dip (°); y3—fault dip score; x4—fracture zone width (m); y4—fracture zone width score.
[0067] 3. Scoring of lining crack length, width and depth ratio:

[0072] 4. Penetration Points
[0073]
[0074] In the formula: x8—penetration points (pieces); y8—penetration points score.
[0075] 5. Lining deterioration residual degree scoring
[0076]
[0077] In the formula: x9—strength residual; y9—strength residual score.
[0078] 6. Score for lining under-thickness reduction ratio
[0079]
[0080] Where: x 10 —Thinning ratio; y 10 —Thinning ratio score.
[0081] 7. Scoring of the circumferential length, radial depth and longitudinal length of the cavity behind the primary support
[0082]
[0083]
[0084]
[0085] Where: x 11 —Circumferential length of the cavity behind the primary support (m); 11 —The score of the circumferential length of the cavity behind the primary support; x 12 —Radial depth of the cavity behind the primary support (cm); 12 — radial depth score of the cavity behind the primary branch; x 13 —Longitudinal length of the cavity behind the primary support (m); 13 —The longitudinal length score of the cavity behind the primary support.
[0086] 8. Score of cross-section intrusion limit
[0087]
[0088] Where: x 14 —Sectional penetration limit (cm); y 14 —Sectional intrusion limit score.
[0089] 9. Base plate uplift score
[0090]
[0091] Where: x 15 —Bottom plate bulge (mm); y 15 —Score for the amount of baseplate rise.
[0092] Calculate the evaluation score for each section:
[0093]
[0094] When the tunnel is divided into n sections, the final score value LJ is calculated according to the formula:
[0095]
[0096] S ci They represent the scores of the 17 indicators of the sub-indicator layer of the i-th section of the tunnel, W Ci represents the weight of the third-level indicator, and Si represents the overall score of the ith section.
[0097] S3, judging the corresponding reuse grades of all pipe segments according to the reuse score corresponding to each pipe segment, and re-dividing the pipe segments whose reuse grades do not meet the preset conditions to obtain multiple sub-pipe segments, and repeatedly executing S1 and S2 with the multiple sub-pipe segments as the multiple pipe segments in S1 until the length of the sub-pipe segment is less than the preset length, and judging whether the in-service pipeline to be determined can be reused according to the reuse grade corresponding to each pipe segment.
[0098] According to the reuse score corresponding to each pipe section, the process of judging the reuse level corresponding to all pipe sections is as follows:
[0099] The reuse score corresponding to each pipe section is determined by Table 1.
[0100] Table 1
[0101]
[0102] Meeting the preset conditions means that the evaluation level is above Level III.
[0103] The preset length refers to a pre-set length, which may be 10 cm.
[0104] If during the repetitive process, a sub-segment fails to meet the preset conditions after repeated processing, the sub-segment will be determined to be unreusable, and the location information corresponding to the sub-segment and an alarm notification that it cannot be reused will be issued, and a final judgment will be made manually to determine whether it can be reused.
[0105] Furthermore, S3 also includes:

[0107] Furthermore, the preset status evaluation system has a three-layer structure, and the three-layer structure corresponds to the primary index, the secondary index and the tertiary index respectively.
[0108] Furthermore, according to the reuse score corresponding to each pipe section, the process of determining the reuse level corresponding to all pipe sections is as follows:
[0109] Based on the preset grade range, the target grade corresponding to the reuse score corresponding to each pipeline section is determined, and the target grade is used as the reuse grade corresponding to the pipeline section.
[0110] In the above embodiments, although the steps are numbered S1, S2, etc., these are only specific embodiments given by the present invention. Those skilled in the art may adjust the execution order of S1, S2, etc. according to actual conditions, which is also within the protection scope of the present invention.
