[0001] The invention relates to the technical field of construction quality monitoring, and more specifically, to a system and method for monitoring the construction quality of bubble lightweight soil. Background Art

[0002] The construction of bubble lightweight soil mainly includes three steps. The first step is the preparation of bubble lightweight soil, that is, adding various raw materials and bubbles into the mixing equipment, and making bubble lightweight soil by mixing. The second step is the pouring of bubble lightweight soil, that is, pouring the bubble lightweight soil into the roadbed. The third step is the maintenance stage of bubble lightweight soil, that is, moisturizing and maintaining the poured bubble lightweight soil. Among them, the first and second steps are the two most important steps in the construction of bubble lightweight soil. In the second step, the bubble lightweight soil needs to be poured in layers. At present, a large number of construction personnel are required to supervise the construction quality during the construction of bubble lightweight soil. At the same time, the construction personnel can only find the problems on the surface during the construction of bubble lightweight soil, and cannot conduct targeted analysis of the problems and make targeted adjustments. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention aims to provide a construction quality monitoring system and method for bubble lightweight soil.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] The construction quality monitoring system of bubble lightweight soil includes mixing quality monitoring module, pouring quality monitoring module and pouring adjustment module;

[0006] The mixing quality monitoring module monitors the mixing effect of the bubble lightweight soil during the mixing process, and determines whether to adjust the mixing conditions based on the comparison result between the mixing quality monitoring value and its threshold value;

[0007] The pouring quality monitoring module monitors the solidification of each layer of the bubble lightweight soil during the pouring process, and determines whether to mark the bubble lightweight soil as solidified foreign soil based on the comparison result of the solidification quality monitoring value and its threshold value;

[0008] The pouring adjustment module is used to obtain the mean value of the environmental impact of solidified foreign soil and take corresponding measures based on the comparison result of the mean value of the environmental impact and its threshold value.

[0009] Furthermore, the stirring effect of the bubble lightweight soil during the stirring process is monitored, and whether to adjust the stirring conditions is determined based on the comparison result of the stirring quality monitoring value and its threshold. Specifically, during the stirring process of the raw materials of the bubble lightweight soil, the bubble density, slurry moisture content and mixing uniformity of the stirring material are obtained every hour, and then a stirring log of the stirring material is generated, and the stirring quality monitoring value of the stirring material is obtained according to the stirring log, and the stirring quality monitoring threshold is set. When the stirring quality monitoring value of the stirring material is less than the stirring quality monitoring threshold, the stirring conditions are adjusted, and the bubble lightweight soil is obtained after the stirring is completed.

[0013] Furthermore, during the pouring process, the solidification of each layer of the bubble lightweight soil is monitored, and based on the comparison result of the solidification quality monitoring value and its threshold, it is determined whether the bubble lightweight soil is marked as solidified foreign soil. Specifically, based on the preset cycle, a new layer of bubble lightweight soil is poured on the roadbed at each cycle node. After the pouring of the new layer of bubble lightweight soil is completed, the roadbed is inspected every t time to generate a roadbed quality monitoring record. The roadbed quality monitoring record includes a solidification performance value, an environmental impact value, and a quality monitoring time. Then, the solidification quality monitoring value of the layer of bubble lightweight soil is obtained, and a solidification quality monitoring threshold is set. When the solidification quality monitoring value of the layer of bubble lightweight soil is greater than or equal to the solidification quality monitoring threshold, the layer of bubble lightweight soil is marked as solidified foreign soil, and the pouring cycle of the next layer of bubble lightweight soil under the solidified foreign soil is extended.

[0014] Furthermore, the solidification performance value recorded by the roadbed monitoring record is obtained by the following method: the wet density and compressive strength of the bubble lightweight soil in the roadbed are collected every t, and marked as SMD and KYD respectively, using the formula The curing performance value is obtained, wherein b1 is the wet density coefficient and b2 is the compressive strength coefficient.

[0015] Furthermore, the environmental impact value of the roadbed monitoring record is obtained in the following way: within a time period of t, the environmental vibration amplitude around the roadbed is detected in real time, and a preset vibration amplitude is set. When the environmental vibration amplitude is greater than or equal to the preset vibration amplitude, a vibration mark record is generated. The vibration mark record includes the vibration amplitude and the vibration mark time. The vibration amplitudes of all vibration mark records are summed and averaged to obtain the average vibration amplitude, which is marked as RWZ. All vibration mark records are sorted in the order of the vibration mark time. The time difference between the vibration mark times of two adjacent vibration mark records after sorting is calculated to obtain the vibration interval. All vibration intervals are summed and averaged to obtain the average vibration interval, which is marked as EYB. The average temperature, average humidity and average light intensity of the environment around the roadbed within a time period of t are obtained and marked as the environmental data set [A1, A2, A3]. The environmental data set is used as the input data of the environmental analysis model to obtain the basic environmental value, which is marked as CSK. The formula is used The environmental impact value SBH is obtained, where a1 is the average vibration amplitude coefficient, a2 is the average vibration interval coefficient, and a3 is the basic environmental value coefficient.

[0016] Furthermore, the solidification quality monitoring value of the bubble lightweight soil is obtained in the following manner: all roadbed material monitoring records of the layer of bubble lightweight soil are obtained, the total number of roadbed material monitoring records of the layer of bubble lightweight soil is marked as TEA, all roadbed material monitoring records are sorted in the order of quality monitoring time, the next adjacent roadbed material monitoring record after sorting is marked as the previous quality monitoring record, and the previous adjacent roadbed material monitoring record after sorting is marked as the post-quality monitoring record, the solidification performance value of the post-quality monitoring record is calculated by difference with the solidification performance value of the previous quality monitoring record to obtain the solidification performance value-added, and the solidification performance threshold value-added is set. When the solidification performance value-added is less than the solidification performance threshold value-added, the number of solidification low increases is increased once, and the number of solidification low increases of the layer of bubble lightweight soil is summed to obtain the total number of solidification low increases, and marked as RZB, and the formula is used. The solidification quality monitoring value ZBT of bubble lightweight soil, where c1 is the total number coefficient of roadbed material monitoring records, and c2 is the total number of solidification low-increase coefficients.

[0017] Furthermore, the mean environmental impact of the solidified foreign soil is obtained, and corresponding measures are taken based on the comparison result of the mean environmental impact and its threshold value, specifically: the mean environmental impact of the solidified foreign soil is obtained, and the mean environmental impact threshold is set; when the mean environmental impact is greater than or equal to the mean environmental impact threshold, the solidified foreign soil is marked as soil that affects environmental quality, and corresponding environmental protection measures are taken for the soil that affects environmental quality; when the mean environmental impact is less than the mean environmental impact threshold, the solidified foreign soil is marked as soil that affects casting method, and the casting method of the soil that affects casting method is adjusted;

[0018] The mean environmental impact of solidified foreign soil is obtained by the following method: all roadbed material monitoring records of solidified foreign soil are obtained, the environmental impact values ​​of all roadbed material monitoring records are summed up and averaged to obtain the mean environmental impact.

[0034] Example 2

[0035] Reference Figure 2 The construction quality monitoring system of bubble lightweight soil includes mixing quality monitoring module, pouring quality monitoring module and pouring adjustment module.

[0036] Mixing quality monitoring module: During the mixing process of the raw materials of bubble lightweight soil, the bubble density, slurry moisture content and mixing uniformity of the mixture are obtained every hour, and then a mixing log of the mixture is generated. The mixing log includes bubble density, slurry moisture content, mixing uniformity, and total mixing time (the total time from the start of mixing to the generation of the mixing quality monitoring value). The mixing quality monitoring value of the mixture is obtained according to the mixing log, and the mixing quality monitoring threshold is set. The mixing quality monitoring threshold is a system-set threshold and can be adjusted according to actual needs. When the mixing quality monitoring value of the mixture is greater than or equal to the mixing quality monitoring threshold, no corresponding processing is performed. When the mixing quality monitoring value of the mixture is less than the mixing quality monitoring threshold, the mixing conditions are adjusted (such as adjusting the mixing speed, adjusting the mixing temperature, and adjusting the water ratio). After mixing, bubble lightweight soil is obtained.

[0037] The stirring quality monitoring value of the stirring material is obtained by the following method: the bubble density, slurry moisture content and mixing uniformity of the stirring log are subjected to data fusion processing (the data fusion processing method can be a weighted fusion method) to obtain stirring fusion data, and the stirring fusion data and the total stirring time are used as input data of the stirring quality monitoring model to obtain the stirring quality monitoring value.

[0038] The stirring quality monitoring model is obtained in the following manner: multiple stirring data groups are set, each stirring data group includes stirring fusion data and total stirring time, the stirring fusion data and total stirring time in the stirring data group can be actual data or preset data, the stirring data group is used as the input data of the neural network model, the stirring data group is assigned a stirring quality monitoring value, the multiple stirring data groups are divided into a training set and a validation set, the training set and the validation set are iteratively trained by the neural network, and the stirring quality monitoring model is obtained. The value of the stirring quality monitoring value is greater than 0. The larger the value of the stirring quality monitoring value, the better the stirring effect of the stirring material corresponding to the current total stirring time.

[0039] The mixing quality monitoring module is set up to dynamically monitor the bubble lightweight soil during the mixing process, dynamically adjust the mixing conditions of the bubble lightweight soil according to the monitoring situation, and effectively control the mixing efficiency of the bubble lightweight soil on the basis of ensuring the mixing quality of the bubble lightweight soil.

[0040] Pouring quality monitoring module: Based on the preset cycle (the preset cycle refers to the conventional pouring interval of bubble lightweight soil, usually not less than 6h), a new layer of bubble lightweight soil is poured on the roadbed at each cycle node. After the pouring of a new layer of bubble lightweight soil is completed, the roadbed is inspected every t time to generate a roadbed quality monitoring record. The roadbed quality monitoring record includes the solidification performance value, the environmental impact value, and the quality monitoring time (the corresponding time for generating the roadbed quality monitoring record). Then, the solidification quality monitoring value of the layer of bubble lightweight soil is obtained, and the solidification quality monitoring threshold is set. The solidification quality monitoring threshold is the threshold set by the system and can be modified according to actual needs. When the solidification quality monitoring value of the layer of bubble lightweight soil is greater than or equal to the solidification quality monitoring threshold, the layer of bubble lightweight soil is marked as solidified foreign soil, and the pouring cycle of the bubble lightweight soil under the solidified foreign soil is extended.

The vibration mark record includes the vibration amplitude and the vibration mark time (that is, the corresponding time of generating the vibration mark record). When the environmental vibration amplitude is less than the preset vibration amplitude, no corresponding processing is performed. The vibration amplitudes of all vibration mark records are summed and averaged to obtain the average vibration amplitude, which is marked as RWZ. All vibration mark records are sorted in the order of vibration mark time.

The formula is used The environmental impact value SBH is obtained, where a1 is the average vibration amplitude coefficient, a2 is the average vibration interval coefficient, and a3 is the basic environmental value coefficient. The value of a1 is 0.82, the value of a2 is 0.76, and the value of a3 is 0.98.
