Buried well of grid reinforced composite structure, and manufacturing method thereof
Provided is a buried well of a grid reinforced composite structure. A well body of the buried well is composed of a fiber reinforced resin-based composite material, the wall thickness of the buried well body comprises an inner lining layer, an inner structural layer, a grid reinforcing rib layer, an outer structural layer and an outer protective layer which are sequentially arranged from inside tooutside, and the grid reinforcing rib layer is positioned between the inner structural layer and the outer structural layer and comprises a plurality of strands of cross-wound yarn bundles wound on the inner structural layer. The buried well of the grid reinforced composite structure is high in strength, long in service life and wide in application range, compared with a brick-built structure shaft, a concrete structure shaft and an annular reinforced glass fiber reinforced plastic shaft, the buried well of the grid reinforced composite structure has higher rigidity, effectively avoids cylinder instability caused by soil covering external pressure, and saves raw materials, is lower in manufacturing cost and has considerable economic benefits because the porosity of the grid reinforced layer can reach 50%.
一种网格增强复合结构埋地井，该埋地井井体采用纤维增强树脂基复合材料构成，其壁厚包括由内至外依次设置的内衬层、内结构层、网格加强筋层、外结构层和外防护层，网格加强筋层位于内结构层和外结构层之间，包括多股交叉缠绕在内结构层上缠绕纱束，本发明一种网格增强复合结构埋地井强度高、使用寿命长、适用范围广泛，与砖砌结构井筒、混凝土结构井筒、环向加筋玻璃钢井筒相比，刚度更大，有效避免由于覆土外压造成的筒体失稳，由于网格增强层空隙率可达50％，节约原材料，造价更低，经济效益十分可观。
