Grouting mixed cement slurry and pipe structure
The invention discloses grouting mixed cement slurry and a pipe structure. The grouting mixed cement slurry comprises the following components in parts by weight: 700 parts of water, 150 parts of bentonite, 75 parts of 425# general silicate cement, 74 parts of talcum powder, 0.5 part of polyacrylamide additive and 0.5 part of carboxymethylcellulose additive. The pipe structure comprises a PE core pipe, an outer pipe sleeve and a cement slurry filling layer, wherein the PE core pipe is inserted in the outer pipe sleeve; and the grouting mixed cement slurry according to claim 1 is cast in the cement slurry filling layer formed between the PE core pipe and the outer pipe sleeve. The grouting mixed cement slurry and the pipe structure can preferably satisfy the mounting, use and maintenance requirements of the PE core pipe. The mixed cement slurry is high in fluidity, and is convenient to be installed; and a cured coagulation adopts a crisp block structure, and has the advantages of proper hardness, good fixing effect, capability of easy stripping and convenience for use and maintenance.
