Glass fiber polyester resin concrete for prefabricated pump station cylinder and preparation method thereof
The invention relates to the field of water supply and drainage, in particular to glass fiber polyester resin concrete for a prefabricated pump station cylinder for water supply and drainage. The glass fiber polyester resin concrete comprises the following components in parts by weight: 75-105 parts of quartz sand, 25-30 parts of high-calcium powder, 25-30 parts of resin, 1-5 parts of a curing agent, 20-30 parts of short glass fibers and 0.2-1 part of an auxiliary agent. The wall thickness of a prefabricated pump cylinder made of the glass fiber polyester resin concrete is generally 110-180 mm, and the defects that an existing prefabricated pump cylinder is not high in strength, small in ring stiffness and prone to deformation and breakage are overcome; the prepared cylinder can be used for open caisson construction and is not prone to deformation, and great economic losses and safety accidents cannot be caused to owners.
本发明涉及给排水领域，具体地说涉及一种给排水用预制泵站筒体用玻璃纤维聚酯树脂混凝土。所述的玻璃纤维聚酯树脂混凝土，包括以下重量份的各组分：石英砂75‑105份、高钙粉25‑30份，树脂25‑30份，固化剂1‑5份，玻璃短纤维20‑30份，助剂0.2‑1份。采用此玻璃纤维聚酯树脂混凝土制作的预制泵筒体壁厚一般在110‑180mm，克服了目前预制泵筒体强度不高，环刚度小，筒体易变形破裂的缺点，制备的筒体可以做沉井施工，不易变形，不会给业主造成重大的经济损失和安全事故。
