Polymer composite manhole cover base and manufacturing method thereof
The invention discloses a polymer composite manhole cover base. The polymer composite manhole cover base comprises a base body, wherein a first through hole is formed in the lower end of the base body, a second through hole is formed in the upper end of the base body, and the inner wall of the second through hole is in sliding connection with a manhole cover body. The invention further puts forward a manufacturing method of the polymer composite manhole cover base. The manufacturing method includes the following steps that S1, polyvinyl alcohol fibers for improving the manhole cover body are added into an abrasion-resistant layer; S2, chemical modification is conducted on the surfaces of reinforced fibers for enhancing the composite manhole cover body; S3, finite element optimization design is carried out; S4, control of molding dimension accuracy and structural stability is realized; and S5, the processing technology is improved, and the production method is improved. The abrasion resistance and ageing resistance of a manhole cover are improved by adding the polyvinyl alcohol fibers, so the service life of the manhole cover is prolonged, and the sundries on the surface of the manhole cover are blown away by compressed gas under the linkage of parts to prevent the sundries from blocking drainage.
本发明公开了一种聚合物复合材料窨井盖底座，包括底座，所述底座的下端开设有第一通孔，所述底座的上端开设有第二通孔，所述第二通孔的内壁上滑动连接有窨井盖本体。本发明还提出了一种聚合物复合材料窨井盖底座的制造方法，包括以下步骤：S1、向耐磨层中加入提高窨井盖本体聚乙烯醇纤维；S2、对增强复合材料窨井盖本体的增强纤维表面进行化学改性；S3、进行有限元优化设计；S4、实现成型尺寸精度和结构稳定性控制；S5、改善加工工艺，改良生产方法。本发明通过加入聚乙烯醇纤维提高井盖的耐磨性和耐老化性，从而提高窨井盖的使用寿命，通过在个部件的联动下压缩气体将窨井盖表面的杂物吹走，以防止杂物遮挡排水。
