This invention discloses a landscape platform-type seawall revetment structure and its construction method. The seawall revetment structure includes a slope-supporting structure, pile foundations, and a permeable floating platform. The permeable floating platform is located on the front side of the slope-supporting structure and abuts against it. By utilizing the slope-supporting structure as the seawall revetment structure and combining the floating platform and the seawall revetment, the revetment functions as both a water-based landscape platform and a seawall revetment while ensuring structural safety, thus improving the single-function nature of the seawall revetment. The construction method of the seawall revetment structure involves steps such as preliminary calculations, pile foundation construction, permeable floating platform construction, and backfilling. The slope-supporting structure and the permeable floating platform structure jointly bear the horizontal force of the seawall behind, effectively reducing land acquisition. This invention, through the landscape platform-type seawall revetment structure and its construction method, expands the water space while ensuring structural safety and reliability.

The first inner drill rod is rotatably fitted inside the first upper outer drill rod and the first lower outer drill rod. The upper end of the first inner drill rod is connected to the first power head, and the lower end of the first inner drill rod is rotatably fitted to the first lower connecting sleeve of the second mixing frame of the lower enlarged head. The lower end of the second outer drill rod is fixed to the upper end of the mixing head of the mixing pile, and the lower end of the second inner drill rod is rotatably fitted to the second lower connecting sleeve of the third mixing frame of the mixing pile. This device has a simple structure, stable and reliable construction process, and accurate and regular pile diameter.

The invention belongs to the technical field of concrete pouring. The underwater concrete pouring device with the exhaust function comprises a guide pipe and a hopper arranged at the top of the guide pipe, an exhaust pipeline is arranged in the guide pipe in the length direction of the guide pipe, a plurality of exhaust holes are evenly formed in the exhaust pipeline in the length direction of the exhaust pipeline, and a drawing mechanism is arranged in the exhaust pipeline; the drawing mechanism comprises a drawing rope arranged in the length direction of the exhaust pipeline and a balance weight plumb bob arranged at the bottom of the drawing rope. The exhaust pipeline arranged in the guide pipe is matched with the drawing mechanism arranged in the exhaust pipeline, so that high-pressure gas in the guide pipe is exhausted, the problem of underwater concrete pouring failure caused by a high-pressure air bag in the guide pipe is solved, and the construction of an underwater concrete guide pipe pouring method is safer and more reliable and has quality guarantee.

This invention relates to the field of intelligent bridge construction technology, and discloses a bridge construction main beam and arch rib alignment control device, including a main beam, arch rib, cable, and controller housing. The arch rib is installed on both sides of the main beam, and the controller housing is installed on the main beam. The cable is installed on the controller housing and fixedly connected to the arch rib. An angle control unit and a tension control unit are installed inside the controller housing. This invention uses a control motor to drive a lead screw shaft to rotate. The rotation of the lead screw shaft causes a change in the position of a sliding sleeve, which in turn causes a guide sleeve to move synchronously. The guide sleeve contains a cable, which in turn moves the bottom of the cable. The connection point between the cable and the arch rib remains constant, causing the cable angle to shift, thus changing the shape. This mechanical operation simplifies the process and allows for direct remote control, making it suitable for widespread application.

This utility model discloses a seepage-proof reinforcement structure for tailings dam drainage culverts, including a drainage culvert body. Inside the drainage culvert body are individually assembleable thin-walled steel pipe sections, with grouting ports pre-installed between the thin-walled steel pipe sections and the drainage culvert body. The upper half of the thin-walled steel pipe sections has a reinforced mesh formed by longitudinally and transversely welded No. 8 threaded steel bars. The bottom of the thin-walled steel pipe sections has circumferentially arranged retractable rollers. A socket-type rubber connector is wrapped around the ends of the thin-walled steel pipe sections. The socket-type rubber connector has a pre-fabricated pressure-bearing elastic self-locking buckle at the end of the thin-walled steel pipe section, along with a matching pressure-bearing elastic self-locking buckle latch. This utility model provides initial reinforcement of the original drainage culvert by setting multiple assembleable thin-walled steel pipe sections inside the drainage culvert, followed by reinforcement and seepage control through grouting. This significantly reduces internal construction work and improves construction safety.
