Abstract

The invention discloses an assembly type rigid supporting protection foundation structure for buried pipelines, and belongs to the technical field of engineering foundations. The assembly type rigid supporting protection foundation structure comprises a foundation, and is characterized by comprising a plurality of supporting units, each supporting unit comprises a precast pile and a pipeline borne by the precast pile, pipeline ports of the two supporting units are in butt joint, each supporting unit further comprises at least one of a prefabricated arch ring and a prefabricated foundation beam, each prefabricated arch ring is supported by the foundation and covers the corresponding pipeline in a buckling mode, a gap is formed between the inner wall of each prefabricated arch ring and the outer wall of the corresponding pipeline, and each prefabricated foundation beam is supported by the precast pile and used for bearing the corresponding pipeline. According to the assembly type rigid supporting protection foundation structure for the buried pipelines, the stress condition of the pipelines can be improved through the foundation structure, the pipeline protection effect is good, durability is high, the construction cost is low, and the construction efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of engineering foundation treatment, in particular to an assembled rigid support protection foundation structure for buried pipelines. Background technique [0002] Pipes used in water supply and drainage projects are generally flexible pipes (including chemical building material pipes, steel pipes, ductile iron pipes, etc.) or rigid pipes (concrete pipes, etc.). Pipeline engineering is an important part of water supply and drainage engineering, and the foundation treatment of pipelines is an important part of pipeline engineering. In the buried pipeline project of slotting construction, there are strict requirements on the foundation settlement under the pipeline and the compaction and backfilling of the soil around the pipeline. When the natural foundation of the pipeline does not meet the construction requirements, the foundation needs to be reinforced with construction measures such as soil replacement ...
