This invention discloses a modular river-crossing pipeline foundation and its assembly method, relating to the field of pipeline engineering technology. It enhances the support and fixation of the river-crossing pipeline, enabling the rapid modular construction of the pipeline in riverbeds or soft soil areas. The modular river-crossing pipeline foundation includes: precast node piles, a load-bearing precast slab, a precast pile extension section, a pipeline connection end, and a mechanical sleeve. The precast node piles are columnar with a central annular platform. The load-bearing precast slab is a plate-shaped body with a through hole at its center, the through hole matching the transverse cross-section of the precast node pile. The lower end of the precast node pile passes through the through hole of the load-bearing precast slab, which is located below the annular platform. The precast pile extension section is columnar, with its lower end connected to the upper end of the precast node pile via a mechanical sleeve. The pipeline connection end is connected to the upper end of the precast pile extension section.

The invention discloses a recycled concrete slope protection brick, and belongs to the technical field of slope protection bricks, the recycled concrete slope protection brick comprises a brick body, the brick body is formed by pressing and curing a recycled concrete raw material, a permeable vegetation structure is integrally formed on the brick body, the permeable vegetation structure comprises a first planting cavity and a second planting cavity, and a vegetation card is poured on one inner wall of the permeable vegetation structure; a receding groove is formed in the position, corresponding to the vegetation clamp, of the lower surface of the brick body, the lower end of the vegetation clamp extends into the receding groove, and the inner wall, opposite to the vegetation clamp, of the water-permeable vegetation structure is designed to be of a downwards-concave inclined face structure. The recycled coarse aggregate and the recycled fine aggregate which are prepared by crushing and screening construction waste are adopted as main raw materials, a large amount of construction solid waste can be consumed, natural gravel exploitation is reduced, energy consumption and environmental pollution are reduced, a large-volume water-permeable vegetation structure is integrated in the brick body, rapid infiltration of rainwater can be achieved, the elastic vegetation cards are embedded in the brick body, and the brick body can be recycled. When vegetation is planted, the vegetation can be automatically and elastically clamped, and the vegetation is prevented from being washed off by rainwater or water flow.
