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.

[0013] Figure 1 This is a schematic diagram of the implementation steps of the method of the present invention. Detailed Implementation

[0014] 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.

[0015] Please see Figure 1 As shown, a method for real-time monitoring and decision-making on casing installation depth includes: Step 1, geological and hydrological data acquisition: monitoring is performed on high-water-level quicksand strata to obtain the geological and hydrological data corresponding to the high-water-level quicksand strata.

[0016] As an optional implementation, the geological and hydrological data includes geological parameters, hydrological parameters, and environmental parameters.

[0017] It should be noted that the geological parameters include the unit weight, void ratio, internal friction angle, and cohesion of the quicksand layer. The unit weight and void ratio of the quicksand layer corresponding to the high water level were obtained using a ring cutter, and the internal friction angle and cohesion of the high water level quicksand layer were obtained using a direct shear tester. The hydrological parameters include the groundwater head and permeability coefficient. The groundwater head corresponding to the high water level quicksand layer was obtained using an immersion-type liquid level sensor, and the permeability coefficient of the high water level quicksand layer was obtained in combination with an electromagnetic flowmeter. The environmental parameters include the distribution of underground pipelines and the foundation type and distance of adjacent buildings. The environmental parameters corresponding to the high water level quicksand layer were obtained using ground-penetrating radar in combination with a total station.

[0018] Step 2: Design of Split-Type Casing: Based on the geological and hydrological data corresponding to the high-water-level quicksand strata, a split-type casing structure corresponding to the high-water-level quicksand strata is designed and verified.

[0019] As an optional implementation, the design yields a split-structure casing for high-water-level quicksand strata. The specific design process is as follows: Based on the geological and hydrological data corresponding to the high-water-level quicksand strata, the characteristics of the high-water-level quicksand strata are extracted, and a corresponding casing is designed according to these characteristics. By adopting a three-section design, flanges and rubber sealing rings are used at the interfaces. Gradient wall thickness and reinforcing ribs are implemented, optimizing the casing wall thickness to a gradient distribution of 8 to 12 mm, and setting corresponding reinforcing ribs to ensure that its lateral pressure resistance reaches greater than or equal to 250 kPa, thus completing the design of the split-structure casing.

[0020] It should be noted that the characteristics include easy collapse of pores in quicksand layers and easy leakage at high water levels; the use of flanges and rubber sealing rings at the interfaces is to improve assembly and disassembly efficiency and sealing performance, and to facilitate rapid splicing and removal of deep sections; the implementation of gradient wall thickness and reinforcing ribs is to effectively prevent local buckling and deformation.

[0021] As an optional implementation method, the verification of the casing corresponding to the high-water-level quicksand strata is carried out as follows: The parameter values ​​corresponding to the designed initial split-structure casing are imported into 3D software. The software will complete the initial construction of the split-structure casing based on the input parameters and the selected target shape, and obtain the three-dimensional initial split-structure casing constructed by the software. The initial split-structure casing is then compared with a preset reference split-structure casing. If the initial split-structure casing is consistent with the preset reference split-structure casing, the initial split-structure casing is determined to be correctly constructed, and subsequent steps are executed. If the initial split-structure casing is inconsistent with the preset reference split-structure casing, the initial split-structure casing is determined to be abnormal, and corresponding corrections are made using the reference model as the standard.

[0022] It should be noted that professional staff set up a reference split-type casing structure, and based on the preset casing parameters, completed the reference construction of the corresponding casing structure. This reference was used to verify the correctness of the corresponding casing construction, so as to ensure that the casing was designed and constructed correctly.

[0023] Step 3: Matching of casing placement parameters: After the verification of the casing is completed, a grouting material ratio experiment is performed on the casing corresponding to the high water level quicksand stratum to confirm the optimal ratio of the casing corresponding to the high water level quicksand stratum, and the matching placement parameters of the casing corresponding to the high water level quicksand stratum are analyzed.

[0024] As an optional implementation method, the grouting material ratio experiment is performed on the casing corresponding to the high-water-level quicksand strata. The specific ratio process is as follows: After the initial design of the casing corresponding to the high-water-level quicksand strata is completed, the geological and hydrological data corresponding to the high-water-level quicksand strata are used to obtain the key condition characteristics of the casing when applied to the high-water-level quicksand strata. Based on the key condition characteristics, the materials for grouting the casing are selected, including the amount of cement, fly ash, quick-setting agent and water-cement ratio. Based on the four aspects of material data corresponding to the casing, each material data is preset to three groups of composition categories, and each grouting split structure casing is designed. The preset tests are carried out on each preset grouting split structure casing, and the experimental data under the test are collected, including slump, setting time, compressive strength and permeability coefficient.

[0025] It should be noted that historical data on the application of casings in high-water-level quicksand strata were extracted from the database, including gap and hole collapse numbers. Based on the casing orientation corresponding to the problem data, the problems were found to be insufficient filling of the gap on the grouting side of the casing and insufficient reinforcement of the hole wall. Therefore, insufficient filling of the gap on the grouting side of the casing and insufficient reinforcement of the hole wall were identified as key characteristics to be considered when using casings in high-water-level quicksand strata, and corresponding optimizations were performed. Flow, solidification, strength, and permeability tests were performed on each of the pre-designed split-structure casings. Professional personnel pre-designed the experimental conditions, such as grouting pressure, experimental duration, and experimental instruments, to obtain complete and effective experimental data, ensuring the effective installation and application of casings in high-water-level quicksand. Experimental data for each split-structure casing under each test were obtained using a slump meter, Vicat apparatus, pressure testing machine, and permeability meter.

[0026] As an optional implementation method, the confirmation process for obtaining the optimal mix ratio of the casing corresponding to the high-water-level quicksand strata is as follows: The experimental data corresponding to each preset grouting split-structure casing is compared with preset reference experimental data intervals. If one or more data points in the preset experimental data corresponding to a certain grouting split-structure casing are not covered within a preset reference experimental data interval, the grouting split-structure casing is deemed unqualified and is removed. If all data points in the preset experimental data corresponding to a certain grouting split-structure casing are within a preset reference experimental data interval, the grouting split-structure casing is deemed qualified, and the grouting parameters corresponding to the grouting split-structure casing are taken as the optimal mix ratio under the corresponding grouting conditions. This analysis yields the optimal mix ratio of the casing corresponding to the high-water-level quicksand strata.

[0027] It should be noted that the preset reference experimental data ranges are set by professional staff. These reference experimental data ranges are to facilitate more accurate grouting of the casing, to give the casing a more complete capability, and to solve defects such as easy grout leakage, poor sealing performance and easy collapse of the hole.

[0028] As an optional implementation method, the analysis obtains the matching sinking parameters of the casing corresponding to the high-water-level quicksand strata. The specific analysis process is as follows: After the optimal grouting ratio corresponding to the casing is obtained, the sinking data corresponding to the casing is acquired. Based on the geological and hydrological data corresponding to the high-water-level quicksand strata, the corresponding numerical simulation is performed to construct a three-dimensional relationship model between the stratum parameters, sinking parameters, and drilling depth. Based on the presented three-dimensional model, when the permeability parameter of the quicksand layer is greater than the preset value, the mud weight is increased, the sinking speed is reduced, and the grouting pressure is increased. When the groundwater head height is greater than the preset value, the length of the lower section of the casing is increased, and the verticality deviation is controlled, thereby completing the matching of the sinking parameters of the casing corresponding to the high-water-level quicksand strata.

[0029] It should be noted that the corresponding simulation model is constructed using FLAC3D software. The software inputs various parameters, and the soft-landing system automatically constructs the corresponding model based on these parameters. The sinking data includes sinking speed, verticality, mud parameters, and grouting parameters. Mud parameters include mud specific gravity and sand content, while grouting parameters include grouting pressure and grouting volume. Historical sinking data for casing applications in high-water-level quicksand strata are retrieved from the database. Preset values ​​are set by staff, serving as reference values ​​to help determine if there are any discrepancies in parameter specific gravity. Staff can then adjust and control these values ​​based on the initial mud specific gravity, reduced sinking speed, grouting pressure, casing lower section, and verticality.

[0030] Step 4: Casing test pile verification: On-site driving simulation of casings corresponding to high water level quicksand strata is performed to obtain the corresponding driving data, evaluate the driving effect of casings corresponding to high water level quicksand strata, and analyze the optimization of casings corresponding to high water level quicksand strata.

[0031] By conducting on-site simulations of casing installation in high-water-level quicksand strata, the corresponding installation data was obtained, the installation effect of casing in high-water-level quicksand strata was evaluated, and the optimization of casing in high-water-level quicksand strata was analyzed. This achieves comprehensive optimization and guarantee of casing performance, further solves the problems existing in casing in high-water-level quicksand strata, and improves casing construction efficiency.

[0032] As an optional implementation, the driving data includes depth error, pile integrity qualification rate, hole collapse accident rate, and single pile casing sinking time.

[0033] It should be noted that the designed casing was simulated and driven on-site. A high-water-level quicksand stratum was selected, and the current casing was used for the corresponding driving. After the driving was completed, driving data was collected using various devices. The depth was obtained using a laser rangefinder and compared with the preset depth to obtain the difference, which was used as the depth error. The total number of piles and the number of damaged piles were obtained using ultrasonic testing. The number of damaged piles was divided by the total number of piles and then multiplied by a percentage to obtain the pile integrity qualification rate. The number of collapsed holes was divided by the total number of piles and then multiplied by a percentage to obtain the hole collapse accident rate. The sinking time of a single pile casing was obtained using a timer.

[0034] As an optional implementation method, the evaluation of the casing installation effect corresponding to the high-water-level quicksand strata is carried out in the following specific evaluation process: the depth error of the casing corresponding to the high-water-level quicksand strata, the pile integrity qualification rate, the hole collapse accident rate, and the single pile casing sinking time are compared with preset reference values. If the depth error of the casing corresponding to the high-water-level quicksand strata is greater than the preset reference depth error value, the pile integrity qualification rate is less than the preset reference qualification rate, the hole collapse accident rate is greater than the preset reference occurrence rate, or the single pile casing sinking time is greater than the preset reference sinking time, then the casing installation effect corresponding to the high-water-level quicksand strata is determined to be unqualified.

[0035] If the depth error of the casing corresponding to the high-water-level quicksand strata is less than or equal to the preset reference depth error value, the pile body integrity qualification rate is greater than or equal to the preset reference qualification rate, the hole collapse accident rate is less than or equal to the preset reference occurrence rate, and the single pile casing sinking time is less than or equal to the preset reference sinking time, then the casing installation effect corresponding to the high-water-level quicksand strata is deemed qualified.

[0036] It should be noted that the reference values ​​are preset by professional staff; the preset reference values ​​are used to more intuitively evaluate whether the casing installation effect is qualified, so as to better improve the casing.

[0037] As an optional implementation, the analysis obtains the optimization of the casing corresponding to the high-water-level quicksand strata. The specific analysis process is as follows: extract the data in the casing installation data that does not conform to the preset reference value and record it as deviation data. Compare the casing deviation data with the preset deviation data to obtain the difference between the two. Compare the casing deviation value with the difference range of each problem item stored in the database. If the casing deviation value is included in the difference range of a certain problem item stored in the database, then the problem item is taken as the structural item to be optimized for the current casing. Optimize the structural item based on the difference value. In this way, the optimization of the casing corresponding to the high-water-level quicksand strata is obtained.

[0038] It should be noted that the difference range for each issue item is based on a summary of historical issues encountered during the application of the casing.

[0039] Step 5: Early warning prompt: When the casing installation effect is not up to standard in high water level quicksand strata, an early warning prompt will be issued.

[0040] This invention, through the acquisition of geological and hydrological data, designs a corresponding split-structure casing and performs corresponding grouting and placement ratio matching on the casing to ensure its high-quality performance. Furthermore, it simulates the on-site installation of the casing in high-water-level quicksand strata to evaluate its installation effect and implement corresponding optimizations. This achieves comprehensive improvement of the casing's function, effectively solving the problems of grout leakage, deformation, and placement difficulties in high-water-level quicksand strata. It further enhances the casing's sealing performance, prevents borehole collapse, strengthens the casing's wall protection effect, prevents casing sinking, tilting, or jamming, ensures pile verticality, and improves the construction efficiency and quality of the casing in high-water-level quicksand strata.
