Description

Technical Field

[0001] This invention relates to the field of waterproofing engineering technology, and more specifically to a method for evaluating the waterproofing level of waterproofing projects. Background Technology

[0002] Waterproofing is a crucial aspect of ensuring the safety and durability of structural connections in buildings and infrastructure. The quality of waterproofing directly affects the lifespan of the project and maintenance costs. In current waterproofing management practices, the classification and evaluation of waterproofing levels are mainly based on national or industry-specific standards and specifications, typically employing either design-level determination or material performance testing methods.

[0003] Existing waterproofing rating technologies include two main approaches: one is based on material performance indicators, which involves standardized testing of waterproofing material samples to ensure that key indicators such as impermeability and seepage resistance serve as the basic standards for determining whether a material meets the waterproofing rating. However, the bonding system between the material and the structural substrate during actual construction cannot be characterized, and it is also difficult to predict the reduction in waterproofing capacity caused by deformation and cracks in the structure during the waterproofing application phase. The second approach is based on empirical grading according to static construction practices, which classifies the waterproofing rating based on static design parameters such as the current engineering location, number of waterproofing layers, and thickness. However, due to the environmental conditions at different construction stages, the treatment quality of the interface and changes in the structural deformation state are unknown and cannot be directly judged. It usually requires subsequent acceptance and quality monitoring to determine the rating. In reality, by the time leakage risks occur, the best remedial opportunity has often been missed.

[0004] In summary, existing methods for evaluating waterproofing levels suffer from problems such as limited evaluation dimensions and ambiguous results. Furthermore, most of these methods are disconnected from the specific construction process and lack a basis for systematic and dynamic correction. Consequently, it is impossible to determine the true waterproofing status and application effect of waterproofing projects throughout their actual lifecycle, thus affecting the scientific validity and application scope of the waterproofing evaluation system. Summary of the Invention

[0005] The purpose of this invention is to provide a method for evaluating the waterproofing grade of waterproofing projects, to solve the subjective technical problem of deviation in waterproofing grade evaluation results caused by the lack of dynamic monitoring, and to improve the accuracy of periodic evaluation of waterproofing materials in collaborative engineering phases.

[0018] Multiple preset waterproofing level evaluation indicators were selected, including structural self-healing ability indicators, structural deformation adaptability indicators, interface synergy indicators, and long-term durability stability indicators.

[0019] Based on practical experience in waterproofing projects, and according to the degree of influence of each waterproofing grade evaluation index on the waterproofing grade, pre-set weight coefficients are assigned to each waterproofing grade evaluation index, including:

[0020] Weighting coefficient of structural self-healing capability index Structural deformation adaptability index weighting coefficient Interface Coordination Index Weighting Coefficient Weighting coefficient of long-term durability and stability index ;and .

This is the structural deformation adaptive normalization function. This is a normalization function for interface coherence. This is the normalization function for long-term durability stability.

[0025] Preferably, in step two, the method for classifying waterproofing evaluation standards using waterproofing grade evaluation indicators specifically includes:

[0026] According to the comprehensive waterproofing evaluation index The numerical range is based on the preset threshold range of the comprehensive waterproof evaluation index. The waterproof rating is divided into several preset levels, among which To preset the minimum value of the comprehensive waterproofing evaluation index, To preset the maximum value of the comprehensive waterproofing evaluation index, the waterproofing level classification specifically includes:

[0027] when ≥ When it is determined to be the first level of waterproofing, it corresponds to a waterproofing system with high self-healing ability, high deformation adaptability, high interfacial adhesion and ultra-long durability;

[0028] when ≤ < At that time, it was determined to be a second level of waterproofing, which corresponds to a waterproofing system with medium self-healing ability, able to adapt to normal structural deformation, and no risk of water seepage at the interface;

[0029] when < When the waterproofing level is determined to be level three, it corresponds to an auxiliary or temporary waterproofing system that has basic waterproofing capabilities but relies heavily on the structure's self-waterproofing.

[0040] The beneficial effects of this invention are:

[0041] (1) By measuring the maximum critical crack repair width of the material and comparing it with the engineering design benchmark, the waterproof safety factor is calculated, the material performance is transformed into an initial quantitative index, and a multi-dimensional evaluation system including structural self-repair capability, structural deformation adaptability, interface synergy and long-term durability stability is established; through phased real-time analysis and construction stage influence coefficient correction, quality defects can be identified in a timely manner during construction, providing data basis for the correction of dynamic waterproof layer, and avoiding the disadvantage of difficult-to-remedy leakage after completion.

[0042] During construction, an impact coefficient for each stage is introduced to correct the measured values ​​of each indicator based on the degree of impact on waterproofing quality at different stages, enabling real-time analysis of the project status. The scores of each indicator at the current stage are compared with preset thresholds, and preset weight coefficients are dynamically adjusted to automatically focus the evaluation on weak links, thereby calculating waterproofing evaluation values ​​that conform to actual working conditions and determining the level. By dynamically adjusting the weights based on the measured scores, the evaluation results more realistically reflect the restrictive effect of weak links on the overall waterproofing level, significantly improving the scientificity, accuracy, and engineering applicability of the waterproofing evaluation system.

[0044] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0045] Figure 1 This is a flowchart illustrating the steps of the waterproofing grade evaluation method for waterproofing projects according to the present invention. Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figure 1 As shown, this invention provides a method for evaluating the waterproofing level of waterproofing projects, the method comprising:

[0048] Step 1: Calculate the waterproofing safety factor based on the benchmark crack width value; set the re-waterproofing performance index value for each waterproofing level evaluation index of the current waterproofing project based on the waterproofing safety factor; and establish a waterproofing evaluation system based on the waterproofing level evaluation index.

[0049] Step 2: Define the standard range of waterproofing evaluation level by using the evaluation index range of waterproofing level for waterproofing projects;

[0050] Step 3: Conduct real-time analysis of the waterproofing status of the project at each construction stage, and calculate the actual weight values ​​of multiple waterproofing level evaluation indicators at the current construction stage.

[0051] Step 4: Input the actual weight values ​​of multiple waterproofing level evaluation indicators into the waterproofing evaluation system to generate the actual waterproofing evaluation value.

[0052] The above technical solution uses tunnel waterproofing engineering as an application scenario to explain the waterproofing level evaluation. It employs the shield tunneling method and combines the self-waterproofing of the segment structure with joint waterproofing materials, designing a waterproofing level of Grade I. The waterproofing level evaluation method for this waterproofing project is completed through the following steps:

[0053] First, in step one, a benchmark crack width value of 0.2 mm was set according to the crack width limit provisions in GB50108, the "Technical Specification for Waterproofing of Underground Engineering". The cement-based penetrating crystalline waterproofing material used in the project was selected as the test object. Based on the penetration test in GB / T50082, "Test Methods for Long-Term Performance and Durability of Ordinary Concrete", the self-repairing ability of this material after cracks appear in the structure was determined. A standard Yanghe and crack simulation test was selected for a period of 28 days, and the maximum critical crack repair width of the waterproofing material was found to be 0.6 mm. When the crack width is less than this value of 0.6 mm, it can repair and seal itself. Further waterproofing performance indicators were determined based on the calculation of the waterproofing safety factor formula.

[0054] The waterproof safety factor k is mapped to a unified scoring scale through a normalization function, and the scoring range is limited by a linear normalization function. The scoring range can be set to 0-100 points, thus limiting the re-waterproofing performance index score of the waterproof material to 60 points. Based on the characteristics of the tunnel project and the experience of relevant technical experts, preset weight coefficients are assigned to each waterproofing level evaluation index, and the actual values ​​of the weight coefficients are dynamically adjusted according to the actual situation. Furthermore, the setting of preset weight coefficients can initially establish a waterproof evaluation system.

[0055] In step two, based on engineering design requirements and engineering experience, a threshold range for the comprehensive waterproofing evaluation index is set. This range can limit the waterproofing level value and guide the level range of subsequent actual waterproofing level evaluation indicators, thereby guiding the generation of actual weight values ​​and improving the accuracy of evaluation within the project cycle. Classifying waterproofing levels can confirm the self-healing ability of waterproofing and match appropriate waterproofing specifications according to project requirements.

[0056] Step three involves real-time analysis of the waterproofing status of the project at each construction stage. The project can be divided into three main phases: Phase 1: segment prefabrication and initial assembly; Phase 2: tunnel boring machine (TBM) advancement and joint construction; and Phase 3: final grouting and finishing. Of course, this can be further subdivided into three or more phases depending on the specific construction stage. In this embodiment, data collection is conducted based on three construction stages. For example, during the second phase of construction, on-site measurements are used to obtain the following dataset:

[0057] Measured value of structural self-healing ability: The crack observation system was used to detect the micro-cracks that appeared in the segments after assembly. The maximum crack width was measured to be 0.15mm. The self-healing ability was calculated by taking the ratio of the crack width to the benchmark value, and the score was 85 (crack control is good).

[0058] Measured values ​​of structural deformation adaptability: During the tunnel boring machine's advance, the opening of the segment circumferential joint was monitored, and the maximum deformation was measured to be 3.5 mm. Based on the compression deformation capacity of the joint sealing gasket (design allowable deformation of 5 mm), it was converted to a score of 70.

[0059] Interfacial compatibility measured value: The bonding strength between the waterproof material and the base layer of the pipe segment was tested using an adhesive strength tester. The average bonding strength was measured to be 1.8MPa. According to the design standard (≥1.5MPa is qualified), it was converted to 90 points (excellent bonding performance).

[0060] Long-term durability stability measured value: On-site sampling and rapid aging test were conducted, and the performance retention rate of the material after aging was measured to be 85%, which is equivalent to 85 points;

[0061] Based on the measured data collection results and the construction organization design of the tunnel project, the influence coefficients of each stage are determined. The following criteria are determined: The quality of the prefabrication stage (first stage) generally has a significant impact on later stages, but can be adjusted through subsequent processes, so it is set to 0.8; the shield tunneling stage (second stage) is the critical period for the formation of the waterproofing system, with the greatest impact weight, so it is set to the maximum value, generally directly impacting the system by 1; later grouting can compensate for some defects, but has limited impact on the already formed structure, so it is set to 0.5; next, the waterproofing rating is calculated by normalizing the measured values ​​of the current stage (second stage), which should include the average of the sum of the waterproofing measurements from the previous stage, and the resulting value is the score after conversion of the measured values.

[0062] Step four involves calculating and generating the actual waterproofing evaluation value. This is done by comparing the scores of various indicators at the current stage with preset threshold ranges. When a set range is reached, dynamic adjustment rules are input: if the score of an indicator is significantly higher than the threshold, some of its weight can be transferred to weaker indicators. After adjustment, an actual weight value is generated. This adjusted actual weight value and the corresponding waterproofing grade score are then substituted into the waterproofing evaluation system model to generate the actual score result. The final waterproofing grade is determined by comparing the actual waterproofing score with the preset grade standard, deciding whether to improve or reduce the original waterproofing grade. Furthermore, the currently weaker indicators can be analyzed in real time, and in subsequent construction, enhanced monitoring can be implemented as needed, such as monitoring joint deformation and taking necessary supplementary grouting and other waterproofing remedial measures to improve the performance of that indicator.

[0063] In summary, the waterproofing safety factor is calculated by using the benchmark crack width and the material's self-healing ability. An evaluation system is established and grade standards are divided. Measured data is collected during key construction stages and stage influence coefficients are considered for real-time analysis. Finally, a waterproofing evaluation value that conforms to the actual situation of the project is generated through dynamic weight adjustment. Moreover, the evaluation results not only quantify the current waterproofing level, but also identify weak links, providing a clear basis for quality control and dynamic adjustment during the construction process.

[0064] As one embodiment of the present invention, the method for calculating the waterproof safety factor in step one is as follows:

[0065] Set the baseline crack width value Determine the baseline crack width value The range of values ​​for;

[0066] The re-waterproofing performance index of waterproofing materials is determined. This index represents the maximum critical crack width at which the waterproofing material can effectively repair itself after cracks appear in the structure. ;

[0067] According to the formula Calculate and obtain the waterproof safety factor .

[0068] In the above technical solution, the material's repair capability is pre-assessed based on the calculated waterproof safety factor, serving as the basis for determining whether there is a risk of leakage; if the waterproof safety factor... A value greater than 1 indicates that the material's repair capacity exceeds the structure's crack tolerance, thus ensuring safety. However, if the waterproof safety factor... If the value is less than 1, it means that once the structural cracks reach the permissible value, the material cannot be effectively repaired, and there is a possibility of leakage.

[0069] As one embodiment of the present invention, the method for setting the re-waterproofing performance index values ​​of each waterproofing level evaluation index of the current waterproofing project based on the waterproofing safety coefficient is as follows:

[0070] Waterproof safety factor By normalization function Mapped to a unified rating scale; where, The scoring range is out of 100.

[0071] Multiple preset waterproofing level evaluation indicators were selected, including structural self-healing ability indicators, structural deformation adaptability indicators, interface synergy indicators, and long-term durability stability indicators.

[0072] Based on practical experience in waterproofing projects, and according to the degree of influence of each waterproofing grade evaluation index on the waterproofing grade, pre-set weight coefficients are assigned to each waterproofing grade evaluation index, including:

[0073] Weighting coefficient of structural self-healing capability index Structural deformation adaptability index weighting coefficient Interface Coordination Index Weighting Coefficient Weighting coefficient of long-term durability and stability index ;and .

[0074] In the above technical solutions, when the waterproof safety factor is... The larger the value, the higher the redundancy of the material's self-healing ability relative to the baseline crack width, resulting in a higher waterproofing performance score and a higher waterproofing safety factor. The smaller the value, the lower the waterproof performance score. Based on this logic, a normalization function is set to precisely satisfy this variation characteristic. The calculation is then performed... ; Verification: When At that time, the score was approximately 63 points, which is considered a borderline passing score. If the score is less than 1, the score drops rapidly, reflecting the current material's insufficient self-healing ability.

[0075] Among them, the structural self-healing capability index characterizes the ability of waterproof materials to repair themselves after cracks appear in the structure, expressed as a normalized waterproof safety coefficient. The base value directly reflects the active waterproofing performance of the material. Among other indicators, the structural deformation adaptability index characterizes the waterproofing system's ability to adapt to structural deformations such as base layer cracking and expansion joint displacement, evaluated by the ratio of joint deformation to the elongation of the sealing material; this index is crucial for ensuring the integrity of the waterproofing system under dynamic loads. The interface synergy index characterizes the bonding strength and synergistic working ability between the waterproofing layer and the structural base layer, determined by pull-out or shear tests, and determines whether the waterproofing system will experience "water leakage". The long-term durability stability index characterizes the rate of performance degradation of the waterproofing material under service conditions, evaluated by the performance retention rate after accelerated aging tests, reflecting the expected service life of the waterproofing system. By covering a multi-dimensional comprehensive evaluation method in the historical waterproofing evaluation index system through four preset waterproofing level evaluation indicators, the reliability, material properties, and construction quality and safety of the waterproofing scheme are improved, making it more comprehensive.

[0076] As one embodiment of the present invention, the process of establishing a waterproof evaluation system includes:

[0077] The waterproofing evaluation system model is established, and the formula is constructed as follows:

[0078] ;

[0079] in, The comprehensive evaluation index for waterproofing; The normalization function for waterproofing performance is determined by the structural self-healing capability index. This is the structural deformation adaptive normalization function. This is a normalization function for interface coherence. This is the normalization function for long-term durability stability.

[0080] In the above technical solution, a calculation model for the comprehensive waterproofing evaluation index F is established based on the preset weighting coefficients and the normalized scoring functions of each indicator; wherein, Determined by normalization of waterproof safety factor; structural deformation adaptability normalization function It needs to be determined based on the measured values ​​of joint deformation; interface coherence normalization function. The determination needs to be based on the measured bond strength; the normalization function for long-term durability stability. It needs to be determined based on the measured values ​​of aging performance.

[0081] As one embodiment of the present invention, step two, the method for classifying waterproofing evaluation standards through waterproofing level evaluation indicators of waterproofing projects, specifically includes:

[0082] According to the comprehensive waterproofing evaluation index The numerical range is based on the preset threshold range of the comprehensive waterproof evaluation index. The waterproof rating is divided into several preset levels, among which To preset the minimum value of the comprehensive waterproofing evaluation index, To preset the maximum value of the comprehensive waterproofing evaluation index, the waterproofing level classification specifically includes:

[0083] when ≥ When it is determined to be the first level of waterproofing, it corresponds to a waterproofing system with high self-healing ability, high deformation adaptability, high interfacial adhesion and ultra-long durability;

[0084] when ≤ < At that time, it was determined to be a second level of waterproofing, which corresponds to a waterproofing system with medium self-healing ability, able to adapt to normal structural deformation, and no risk of water seepage at the interface;

[0085] when < When the waterproofing level is determined to be level three, it corresponds to an auxiliary or temporary waterproofing system that has basic waterproofing capabilities but relies heavily on the structure's self-waterproofing.

[0086] As one embodiment of the present invention, step three includes:

[0087] Obtain identification information for the current construction phase. ,in, ; This represents the total number of construction phases.

[0088] Collect data at the current construction stage. Engineering waterproofing test data set ;in, Indicates the current construction phase Measured values ​​of the structure's self-healing capability; Indicates the current construction phase Measured values ​​of structural deformation adaptability; Indicates the current construction phase Measured values ​​of interface collaboration; Indicates the current construction phase Measured values ​​of long-term durability stability;

Corresponding waterproof rating evaluation indicators; Current construction phase No. The waterproof rating score for each waterproof rating indicator; For the first The normalization function corresponding to each evaluation index; Current construction phase The construction stage impact coefficient is preset based on the degree of impact of each construction stage on waterproofing performance, and ∈ .

[0092] In the above technical solution, the waterproofing project is divided into three main construction stages based on the tunnel shield method construction process, and each stage is assigned a stage identifier. Based on engineering experience and the degree of influence of each stage on the final waterproofing quality, an influence coefficient for each construction stage is pre-set. Further, based on the specific construction stage, actual measurement data was collected and normalized. A crack width observation instrument was used to detect surface cracks near typical joints within 24 hours after the segment assembly, and the maximum crack width was taken as the measured value. Acquisition of measured data: According to on-site testing, the maximum crack width in this stage is 0.15. The measured data corresponding to the maximum crack width was determined and the waterproofing grade score value of each waterproofing grade evaluation index in the current stage was obtained.

[0093] As one embodiment of the present invention, the method for calculating the actual weight values ​​of multiple waterproofing level evaluation indicators in step three of the current construction stage is as follows:

The actual weight values ​​of the structural self-healing ability index are also obtained. Actual weight value of structural deformation adaptability index Actual weight value of interface collaboration index Actual weighting value of long-term durability stability index ;

[0095] Furthermore, in step four, the actual weight values ​​of multiple waterproofing level evaluation indicators are input into the waterproofing evaluation system to generate the actual waterproofing evaluation value, including:

[0096] actual weight value , , , and the corresponding waterproof rating value , , , Substitute into the waterproofing evaluation system model to obtain the actual waterproofing evaluation value. Calculation: .

[0097] In the above technical solution, the waterproofing level score and lower limit threshold of each waterproofing level evaluation index are calculated. The deviation value is defined to characterize the degree to which an indicator deviates from the pass line. Adjustments are allocated according to the deviation ratio. When calculating the total deviation value, the preset weight of indicators with relatively high scores is decreased by 15 percentage points, while the weight of indicators with relatively low scores is increased by 15 percentage points. The final weight values ​​are then determined after adjustment. The adjusted weights are summed to 1. Finally, the actual waterproofing evaluation value is calculated by substituting the actual weight values ​​and corresponding waterproofing grade scores into the waterproofing evaluation system model to determine the final waterproofing evaluation value. ,when Less than the preset lower limit value If the waterproofing level is not met according to the waterproofing level standard in step two, the waterproofing status at the current construction stage is determined to be the third waterproofing level; otherwise, it is determined to be the first or second waterproofing level. In actual construction, it is necessary to improve and correct any unqualified indicators in a timely manner, and to achieve effective control of waterproofing at the construction stage by means of secondary tightening of the joint sealing gasket, strengthening grouting control, and supplementing interface reinforcement treatment.
