This invention relates to the field of caisson bottom sealing construction technology, and discloses a dynamic sealing sludge and water inrush sealing system for caissons. The system integrates a bottom sealing template assembly, a dynamic sealing baffle, a novel quick-setting sealing grout injection assembly, a drainage and pressure relief assembly, a fixing and anchoring assembly, and an anti-sludge isolation assembly. The bottom sealing operation is completed through an integrated process of layered sealing, immediate curing, and simultaneous bottom sealing. During construction, the base is first cleaned and the components are installed; after the dynamic sealing baffle is deployed, it is hydraulically attached to the base plate and the water inrush point is detected; then, quick-setting grout is injected into the leakage area in a targeted manner, and drainage and pressure relief are simultaneously activated to regulate the pressure; after the grout has quickly set, the baffle is retained as a permanent water-stopping structure; finally, underwater concrete is continuously injected through a pre-set pipeline, and an anti-sludge isolation layer is set to ensure the density of the concrete. This system simultaneously achieves rapid water inrush sealing, dynamic pressure balance, and high-quality bottom sealing, solving the problems of poor sealing time, poor process connection, and difficulty in controlling the quality of underwater concrete in traditional processes.

The invention relates to the technical field of geotechnical engineering and foundation treatment, in particular to an adjustable hydraulic distraction device for preventing and treating ground surface settlement and a construction method, and the adjustable hydraulic distraction device comprises a central supporting steel pipe, a hydraulic driving unit, an umbrella rib supporting structure and a grouting system; a hydraulic driving unit and an umbrella rib supporting structure capable of being unfolded in the radial direction are arranged in the center supporting steel pipe, and the grouting system is connected with the center supporting steel pipe and grouts into the unfolded umbrella rib supporting structure and a peripheral cavity. Through a reliable and adjustable driving mode, a supporting structure similar to an umbrella rib is unfolded in time, strong and uniform radial extrusion force is generated, and a soil body is effectively compacted. Meanwhile, the supporting state can be dynamically adjusted according to stratum deformation, and long-acting and active prevention and control of sedimentation are achieved.

This utility model discloses a conveying device for processing Chinese medicinal materials, relating to the field of Chinese medicinal material processing technology. It includes a support section, a conveying section, and a circulation section. The support section allows for flexible adjustment of the conveying angle, enabling multi-process integration without additional equipment or manual labor. Rollers are installed at the bottom of the base plate for easy movement. The conveying section, mounted on a movable plate, includes a conveying cylinder with a feed hopper at one end and a discharge port at the other. An internal conveying shaft is connected to a conveying motor via a coupling. A detachable conveying side plate at the end facilitates maintenance. The circulation section surrounds the conveying cylinder and consists of a circulating water tank, a motor, and a circulation pipe. The circulation pipe is connected to the water tank at both ends. The motor drives an impeller to circulate cooling water, quickly removing frictional heat. A drain pipe with a solenoid valve is located at the bottom of the water tank. Filter screens are installed at both ends of the circulation pipe. The conveying cylinder and circulation pipe are made of copper to improve heat conduction and temperature control, ensuring the quality of the medicinal materials.

The utility model relates to bridge shell raw material processing technical field discloses a bridge shell raw material heat treatment device, including trolley furnace body, one side of trolley furnace body rotatably connected has the furnace door, is provided with the track no.

The present application relates to the technical field of hot box, and provides a hot box door locking mechanism, a hot box and a false twist texturing machine.The hot box door locking mechanism comprises at least one pressing mechanism, a transmission shaft for driving the pressing mechanism to rotate, and a pressing handle for driving the transmission shaft to rotate.The pressing mechanism comprises a rotating pressing piece and a retaining assembly.The transmission shaft penetrates through the retaining assembly and is connected with the rotating pressing piece.The pressing handle rotates to form a first shaft.During the process of driving the rotating pressing piece to rotate by the transmission shaft, the rotating pressing piece and the hot box door change from being separated from each other to being in contact with each other, so as to press the hot box door to rotate to a closed state surface.The present application drives at least one pressing mechanism by the pressing handle to apply a pressing force to the edge area of the hot box door, so as to press the hot box door to rotate to a closed state surface, thereby solving the problems of heat loss and high energy consumption caused by the fact that the hot box door cannot be effectively closed to heat the cavity.

This utility model relates to the technical field of automatic pipe packaging and loading equipment, and in particular to an online automatic packaging and loading device for small-diameter pipes. It includes a transmission module and a bundling module. A lifting module is provided on one side of the bundling module, and the lifting module includes a conveyor platform. An electromechanical control box is located on the left side of the conveyor platform, and a side support is bolted to the back of the conveyor platform. This utility model uses a servo motor in the lifting module to drive a belt to lift and bundle the pipes, and a series of gears work together to automatically complete the pipe flipping and loading operation. This completely replaces the heavy manual labor of short-distance handling and lifting pipes to the loading platform. The bending design at the end of the lifting plate stably restrains the pipes, and the drive motor provides high-torque flipping force through the gears, eliminating the need for employees to participate in the handling process and fundamentally alleviating the problems of back injuries and complaints caused by long-term labor.

The application discloses a kind of urban rail fault root cause automatic analysis method and system based on industry knowledge graph and big model.The method extracts knowledge from unstructured historical maintenance records and technical manuals automatically, constructs the knowledge graph of urban rail operation and maintenance;Using fine-tuned vertical field large language model, combined with real-time monitoring data and graph search results, automatically generate natural language diagnostic report containing fault root cause, risk level, maintenance scheme and spare parts list.The application effectively solves the pain points of difficulty in digitizing expert experience, dependence on manual consultation of manuals in urban rail operation and maintenance, significantly improves the intelligent level, accuracy and efficiency of fault diagnosis, and realizes the decision-making closed-loop support of operation and maintenance.
