Abstract: A road structure reconstructed from large-scale independent underground garage and a construction method, which solves the problem of a newly constructed urban expressway passing through large underground space. The technical point is a construction method for the road structure reconstructed from large-scale independent underground garage, including the following steps: S100: segmentation for the garage, S200: preparation before construction: the materials and equipment required for construction are transported to the site, and the construction site is cleaned, S300: reconstruction for the front section, S400: reconstruction for the middle section, S500: reconstruction for the rear section. The inventiveness of the present disclosure is the application of segmentation construction, the front section is completely obsoleted, a transition section is provided at the middle, and the design of the rear section adopts a double-deck road, thus the original underground garage structure is fully utilized.

Abstract: An inflatable folding tunnel reinforcement structure and a construction method thereof are provided. The inflatable folding tunnel reinforcement structure includes an inflation port, an airbag, a water blocking net, a steel plate, a scissor folding mechanism, a vertical support plate, an arc-shaped support plate, drainage channels, an upper support rod, a lower support rod, a locking pin, a threaded steel rod, a rolling connection pin, and an induction motor, where the upper support rod and the lower support rod are unfolded in opposite directions to a preset position through the steel rod; and the drainage channels are configured to perform water guidance and resistance for a leakage-proofing purpose. The construction method includes: preparation before construction, device fixation, on-site construction, structural inspection, and site cleaning. The present disclosure can treat various tunnel defects efficiently and conveniently and achieve a desired leakage-proofing effect.

Abstract: Methods using novel cathode, electrolyte and oxygen separation materials operating at intermediate temperatures for use in solid oxide fuel cells and ion transport membranes include oxides with perovskite related structures and an ordered arrangement of A site cations. The materials have significantly faster oxygen kinetics than in corresponding disordered perovskites.

Abstract: A device and method for separating water into hydrogen and oxygen is disclosed. A first substantially gas impervious solid electron-conducting membrane for selectively passing protons or hydrogen is provided and spaced from a second substantially gas impervious solid electron-conducting membrane for selectively passing oxygen. When steam is passed between the two membranes at dissociation temperatures the hydrogen from the dissociation of steam selectively and continuously passes through the first membrane and oxygen selectively and continuously passes through the second membrane, thereby continuously driving the dissociation of steam producing hydrogen and oxygen. The oxygen is thereafter reacted with methane to produce syngas which optimally may be reacted in a water gas shift reaction to produce CO2 and H2.
