  • Patent number: 11566523
    Abstract: A microorganism curing anti-seepage device based on capsule transmission and control includes a stock bin which includes a mixing bin and an oil storage bin separated from the mixing bin. A feed pipe and an oil injection pipe are provided on the stock bin. A central shaft is rotatably provided within the mixing bin. A stirring component is provided on the central shaft. A delivery pipe is provided at a bottom portion of the mixing bin, an oil conduit is provided at a bottom portion of the oil storage bin, a jet pipe is provided at a junction of the oil conduit and the delivery pipe. Since microbial capsules are decomposed layer by layer, after the microbial capsules reach fissures, the microbial bacteria, the nutrient solution and the curing liquid are released step by step, and then calcium carbonate is induced by microorganisms to achieve solidification and anti-seepage of fissures.

  • Patent number: 11441357
    Abstract: A drilling platform for amphibious operations includes: a base, wherein drive tracks are arranged on both sides of the base, a propeller is disposed at a rear end of the base, and a driving assembly is disposed inside the base; two support cylinders are respectively disposed at two ends of the base; each of the support cylinders contains a sub-cylinder; a pushing cylinder is arranged on a bottom surface of the partition plate; a buoyancy adjustment assembly is provided at a bottom of the base, so as to provide buoyancy support for the base when the base is transferred from land to water. The present invention is suitable for drilling construction of pile foundations of water and land buildings, bridge piers, and transmission line electric tower pile foundations, as well as drilling of oil wells, wherein the drilling platform construction process at different drilling points is omitted.
