High-strength light composite sounding pipe and preparation method thereof
The invention relates to the technical field of sounding pipes, and provides a high-strength light composite sounding pipe and a preparation method thereof. A high-strength light composite sounding pipe sequentially comprises a galvanized steel corrugated pipe, a mortar layer and a steel pipe from inside to outside. The mortar layer is prepared from the following raw material components in parts by mass: 25 to 35 parts of cement, 20 to 30 parts of sand, 15 to 25 parts of fly ash, 1.5 to 2.5 parts of mineral powder, 0.5 to 1.5 parts of silica fume, 1.5 to 2.5 parts of redispersible latex powder, 5 to 10 parts of 4-amino-3-sulfo-1, 8-naphthalene anhydride modified fiber, 0.1 to 0.2 part of cellulose, 0.1 to 0.3 part of a water reducing agent and 15 to 25 parts of water. By means of the technical scheme, the problems that in the prior art, fibers are not evenly dispersed in mortar and prone to agglomeration and balling are solved.
本发明涉及声测管技术领域，提出了一种高强度轻质复合声测管及其制备方法。一种高强度轻质复合声测管，由内至外依次包括镀锌钢质波纹管、砂浆层和钢管；砂浆层的原料包括以下质量份的组分：水泥25~35份、砂20~30份、粉煤灰15~25份、矿粉1.5~2.5份、硅灰0.5~1.5份、可再分散乳胶粉1.5~2.5份、4‑氨基‑3‑磺基‑1,8‑萘酸酐改性纤维5~10份、纤维素0.1~0.2份、减水剂0.1~0.3份、水15~25份。通过上述技术方案，解决了现有技术中的纤维在砂浆中分散不均、易团聚成球的问题。
