This invention discloses a dynamic adaptive ecological slope protection system and method suitable for reservoir bank drawdown zone slopes, belonging to the field of water conservancy engineering and ecological restoration. The system includes an anchoring system, a lifting vegetation trough, an integrated water collection system, and a linked water supply device. The anchoring system uses self-weight triggered self-locking anchors to achieve locking upon installation. The vegetation trough can freely rise and fall along the anchors with the water level, and contains a soil layer and a water-storing sponge layer. The water collection system automatically controls water flow through a float valve, and the linked water supply device relies on elastic expansion and capillary action to achieve water storage during submersion and automatic water supply during emergence. Construction adopts a bottom-up modular installation, using the floating plate of the vegetation trough as a working platform, eliminating the need for high-altitude facilities. This invention can adapt to the off-season hydrological rhythm of the drawdown zone, improving slope stability and vegetation survival rate. It requires no external energy or human intervention and has advantages such as convenient construction, low operation and maintenance costs, and eco-friendliness, making it suitable for ecological protection of reservoir and lake drawdown zone slopes.

The invention relates to an anti-sedimentation bridge girder erection machine front supporting leg device and a construction method thereof.The anti-sedimentation bridge girder erection machine front supporting leg device comprises a main beam, a lifting mechanism and a supporting rod, the lifting mechanism is provided with a first connecting part and a second connecting part, the supporting rod is provided with a first connecting matching part and a second connecting matching part, and when the first connecting part is connected with the first connecting matching part, the second connecting matching part is matched with the first connecting matching part; when the second connecting part and the second connecting matching part are disconnected, the supporting rods are static relative to the lifting mechanism, and the second connecting part and the second connecting matching part are connected, the first connecting part and the first connecting matching part are disconnected, the lifting mechanism drives the supporting rods to move downwards, automatic plug pin mechanisms are arranged on the supporting rods, and a movable beam is arranged between the two supporting rods. According to the anti-sedimentation bridge girder erection machine front supporting leg device and the construction method thereof, the supporting rods are pressed by the oil cylinders to be inserted into a seabed or a riverbed to avoid sedimentation of the bridge girder erection machine during construction, the bottom ground supporting area is increased through the movable beams, stress is uniform and reasonable, safety and reliability are achieved, and the safety and stability of the bridge girder erection machine are enhanced.

This utility model relates to the field of inclined shaft construction technology and discloses a work trolley for installing pressure steel pipes in inclined shafts. The work trolley includes a trolley body and an operating platform located in the pressure steel pipe. The trolley body consists of a traveling beam and an equipment platform. One end of the equipment platform is rotatably connected to the traveling beam via a hinge device, and the other end is movably connected via an adjustable support connection mechanism. An independent hydraulic pump station on the equipment platform forms a closed-loop drive system with the mechanism, which can continuously adjust the angle of the equipment platform to keep it horizontal in the lower bend section, straight pipe section and upper bend section of the inclined shaft. The operating platform is leveled synchronously with it. It can also adapt to the curvature of the bend section by adjusting the angle, eliminating the need to erect scaffolding and improving construction efficiency.

The application discloses a cable-stayed spiral single straight anchor and a construction method thereof, and belongs to the technical field of anchor fixing of geotechnical engineering. The spiral single straight anchor comprises a spiral anchor rod and spiral blades. The spiral anchor rod is of a hollow structure. The spiral blades are arranged in a continuous non-equidistant shape on the lower part of the spiral anchor rod in the axial direction. The spiral blades are of a variable-diameter structure with a small upper part and a large lower part. A plurality of inclined barbs are arranged on the surface of the blades. The tips of the barbs are arranged in the opposite direction of the anchor rod rotation direction. The pitch of the spiral blades gradually decreases from bottom to top. The upper part of the T-shaped rod is a horizontal rod which is hung on the top port of the spiral anchor rod. The lower part of the T-shaped rod is a vertical rod. The cable-stayed spiral single straight anchor and the construction method thereof can effectively improve the anchoring force, can be adapted to different cable directions, and can improve the applicability.
