This utility model relates to an embedded steel-clad wood-concrete composite beam, belonging to the field of composite beam technology. It includes a concrete slab with a trapezoidal groove extending along its length at the bottom. A wooden beam is positioned below the concrete slab, and the wooden beam has trapezoidal protrusions that mate with the groove, inserted into the groove. Several shear pins are arranged along the length of the wooden beam, fixing it to the upper part. An outer steel beam with a rectangular cavity is positioned below the concrete slab, and the wooden beam is embedded within this cavity. Two sets of barbed bolts are provided on the concrete slab, located on opposite sides of the trapezoidal groove. This utility model utilizes the compressive strength of steel and the tensile strength of wood in synergy, achieving efficient connection through mortise and tenon joints, pins, and bolts, enhancing overall load-bearing capacity and stability. It is suitable for large spans and negative bending moment areas, possessing excellent assembly adaptability and durability.

The utility model discloses a modularization soil retaining block for slope water and soil conservation relates to soil retaining block technical field, aims at solving the technical problem of poor integrality of existing modularization soil retaining block, and the insufficient problem of cooperative shearing capacity, including block body, the block body inside is provided with at least two passages, is first passage and second passage respectively, first passage and second passage inside are provided with fixed establishment, the fixed establishment inside is provided with auxiliary mechanism, the utility model discloses a conical hopper is set up in the block bottom and is set up the guide mouth of matching with it on its top, so that the upper and lower layer block can be automatically aligned when the pile is built and forms mechanical interlocking through the meshing of the toothed block and the limiting tooth groove. Make all the blocks interlock into an organic whole, greatly enhance the integrality and stability of the retaining wall, solve the problem of poor integrality of existing modularization soil retaining block, and the insufficient problem of cooperative shearing capacity.
