This invention relates to the field of pipeline seepage prevention technology, specifically to a pipeline seepage prevention deformation control support device based on soft soil foundation. The device is installed at the connection point of two adjacent pipelines. The device includes a bearing ring, a support member, and at least n sets of limiting members. Bearing rings are connected to the outer walls of both pipelines near the connection point. Each set of limiting members includes two bearing plates, arranged in an inverted V-shape with alternating front-to-back arrangements. Each bearing plate has a recessed groove containing a friction plate that slides back and forth. When the lower left side of the n bearing plates on the left side of the n sets of limiting members is far from the lower right side of the n bearing plates on the right side, the two friction plates in the same set make relative pressure contact. The support member supports the limiting members. This invention solves the problem that when a support device supports a pipeline, it easily shifts downwards with the settlement of the soft soil foundation, leading to deformation and leakage at the weak connection point of the supported pipeline.

This invention provides a multi-energy field assisted ultrasonic cutting device and method for CFRP preforms, relating to the fields of intelligent manufacturing and precision machining technology. The invention uses a laser generator to precisely and locally heat the cutting area, softening the resin matrix in the processing area and significantly reducing the material's strength and cutting resistance. Simultaneously, eddy current tubes cool the non-cutting areas of the workpiece, enhancing the stiffness of the resin matrix in these areas and the constraint force on the carbon fibers, effectively suppressing excessive deformation and displacement of the carbon fibers during processing. Ultrasonic vibration further induces brittle fracture of the carbon fibers through high-frequency impact, reducing the tensile effect caused by resin viscosity. Ultimately, this achieves the beneficial effects of high-quality, high-efficiency, and low-damage processing of CFRP preforms.

This utility model discloses a multi-layered wear-resistant EVA sole, including a foot instep layer. The sole incorporates a shock-absorbing layer and a wear-resistant layer. The shock-absorbing layer utilizes a honeycomb-shaped EVA material support structure with a biomimetic structure to achieve lightweighting. The elastic deformation of the pore walls disperses foot pressure. A high-density design in the heel enhances support stability and prevents excessive deformation. The first and second air cushions in the forefoot and heel are respectively rectangular to accommodate lateral force from the forefoot and circular to accommodate vertical impact from the heel, improving dynamic shock absorption and absorbing the impact force on the foot during exercise, reducing fatigue and injury. The wear-resistant layer is designed in three sections: forefoot, midfoot, and heel. Appropriate materials can be selected for different areas to extend the overall lifespan. The segmented structure, combined with the fastening buckles and insertion holes, and the matching grooves on both sides of the fastening buckles and insertion holes, enhances the connection between the wear-resistant layers. This allows for individual replacement after localized wear, eliminating the need for complete replacement, effectively reducing usage costs and material waste, and balancing practicality and environmental protection.
