This utility model relates to the field of river management engineering technology, specifically to a gravity retaining wall for river landscape. It includes a base slab and a wall body. The water-facing side of the base slab is equipped with a toothed wall and pre-embedded U-shaped steel bars, connected to gabion cages by steel wire ropes to resist erosion. Pre-embedded stones on the top surface of the base slab enhance its interlocking with the wall body. The water-facing side of the wall body is faced with pebbles to enhance its aesthetics, and a planting groove is provided at the top for planting greenery. The wall body has a built-in dual drainage system: a first drainage pipe directs water from behind the wall into the planting groove for irrigation, and a second drainage pipe is dedicated to pressure relief drainage; both have a slope of 5%. This utility model integrates flood control, landscape, and ecological functions, solving the problems of poor water affinity and insufficient erosion resistance of traditional retaining walls.

This invention discloses a prefabricated assembled foundation for wind turbine towers, combining a spherical shell and a conical shell, and its construction method. Belonging to the technical field of wind turbine tower foundations, the prefabricated assembled foundation includes: a spherical shell foundation body comprising multiple prefabricated spherical shell components, the spherical shell foundation body having a downwardly convex spherical shell shape; a conical shell foundation body arranged on the upper side of the spherical shell foundation body, the conical shell foundation body having a conical shell shape and comprising multiple prefabricated conical shell components; and a ring beam connecting the conical shell foundation body and the spherical shell foundation body, the ring beam comprising multiple prefabricated beam components, the multiple prefabricated beam components being spliced ​​and connected along the circumference of the spherical shell foundation body. The prefabricated assembled foundation for wind turbine towers based on the spherical shell and conical shell combination of this invention can fully utilize the advantages of thin-shell foundations, such as reasonable stress distribution and material saving. The cavity enclosed by the foundation can be filled with counterweights to improve the foundation's overturning stability. The use of prefabricated components can significantly shorten the on-site construction cycle and ensure the consistency of foundation construction quality.

The present application relates to the technical field of hydraulic engineering, and particularly relates to a water level monitoring device, which comprises a vertical pipe, a floating assembly and a monitoring assembly arranged in the vertical pipe, a protection assembly, a drilling and inserting positioning assembly and an expansion assembly sleeved on the outside of the vertical pipe. When in use, the handle rod at the upper part of the vertical pipe is rotated to drive the drilling and inserting positioning assembly to rotate and drill into the ground, thereby realizing four-point synchronous anchoring. Meanwhile, the downward movement of the drilling and inserting positioning assembly pushes the multiple expansion support rods to expand outward through the adjusting mechanism, thereby effectively increasing the bottom support area. When the water level in the tunnel rises, the laser ranging sensor monitors the distance change between the laser ranging sensor and the reference sheet in real time, and the data is processed by the PLC controller to display the real-time water level. The present application effectively avoids impurity interference through the built-in monitoring system and the external filtering structure, thereby ensuring the monitoring accuracy. The four-point rotary drilling anchoring and the expandable support rod design significantly improve the anchoring efficiency and the anti-overturning stability, and are particularly suitable for complex working conditions such as underpass tunnels.
