This invention discloses a diagnostic and reinforcement method and system for rotary kiln foundation pile foundations, relating to the field of rotary kiln testing technology. The method includes: acquiring vibration data; determining whether the vibration originates from structural damage to the foundation based on the correlation between the vibration data and the rotary kiln's rotation frequency; if so, scanning all engineering piles to determine the defect type, location, and loss depth range of each pile; determining the critical depth at which each pile can still provide effective embedment under its current state based on the defect information, and assessing the overall remaining horizontal bearing capacity and flexural bearing capacity; and reinforcing based on the assessment results. The reinforcement system includes an integral composite pile cap consisting of an existing pile cap and a newly constructed, deepened pile cap, as well as multiple newly added pile foundations installed on the newly constructed, deepened pile cap.

A method for measuring the embedment depth of proppant in hydraulic fractures of original reservoirs belongs to the field of oil and gas field development technology. By selecting rock blocks containing hydraulic fractures, rock samples with similar lithology and fracture morphology are prepared as test samples and control samples. Propane is laid on the fracture surface of the test samples, and the samples are fixed using heat-shrink tubing. Both types of samples are placed in a mechanical testing machine and tested under the same conditions. The load-displacement curves of the two samples are recorded. The displacement value of the test sample during loading and unloading is subtracted from the displacement value of the control sample to obtain the total elasto-plastic deformation value and the elastic deformation value during proppant embedding. The difference between the two is the plastic deformation value, i.e., the proppant embedment depth. This method can accurately reflect the characteristics of original hydraulic fractures in reservoirs, effectively eliminate the interference of sample deformation, is simple to operate, and has strong applicability, providing a quantitative basis for the selection of hydraulic fracturing proppant and the optimization of construction parameters.

This invention discloses a construction method for pre-embedding and positioning anchor bolts for large vertical tower foundations. It employs a combined positioning and reinforcement system integrating "reference center positioning, dual-control positioning using fixed radius and fixed chord length, and a double-constraint support system," effectively solving common technical challenges in the industry such as the large number, large diameter, deep embedment, easy displacement during casting, difficulty in controlling pre-embedding accuracy, high rework rate, and low construction efficiency of anchor bolts in large industrial towers. This method achieves high-precision positioning, high-stability fixing, and one-time pre-embedding of anchor bolts, ensuring that the spacing between adjacent bolts, circumferential coaxiality, concentricity, and verticality meet high-precision installation requirements. The measured accuracy indicators in engineering projects are: axis deviation ≤ 2mm, adjacent bolt spacing deviation ≤ 2mm, elevation deviation 0~+3mm, verticality deviation ≤ L / 450, and coaxiality and concentricity deviation ≤ 2mm.
