Preparation method of high-strength corrosion-resistant concrete pipe pile
The invention discloses a preparation method of a high-strength corrosion-resistant concrete pipe pile. The preparation method comprises the following steps: S1, weighing 32-42 parts by weight of river sand, 18-35 parts by weight of stone, 3-11 parts by weight of crushed crude pearlite, 1-5 parts by weight of superfine mineral powder, 85-125 parts by weight of cement, 7-22 parts by weight of modified plant ash, 1-9 parts by weight of a water reducing agent, 6-54 parts by weight of slag, 4-21 parts by weight of alkali silicate, 1-8 parts by weight of polypropylene fiber and 42-72 parts by weight of water; S2, mixing the river sand, the stones, the crushed crude pearlite and the slag, adding the mixture into a crusher, and crushing to obtain a mixture A; the river sand, the stones, the perlite powder and the slag which are not uniformly crushed are finely crushed through the driving crushing roller and the driven crushing roller which rotate in the inner cavity of the crushing box, so that the particle sizes of the river sand, the stones, the perlite powder and the slag are more uniform, and the structural strength of the concrete pipe pile is improved.
本发明公开了一种高强度耐腐蚀混凝土管桩的制备方法，S1：以重量份计称取河沙32‑42份、石子18‑35份、珍珠岩粉3‑11份、超细矿粉1‑5份、水泥85‑125份，改性草木灰7‑22份、减水剂1‑9份、矿渣6‑54份、硅酸碱4‑21份、聚丙烯纤维1‑8份和水42‑72份；S2：将河沙、石子、珍珠岩粉和矿渣混合后加入粉碎机中粉碎，制的混合物A；通过破碎箱内腔转动的主动破碎辊和从动破碎辊将粉碎不够均匀的河沙、石子、珍珠岩粉和矿渣进行精细粉碎，从而使河沙、石子、珍珠岩粉和矿渣的粒度更加均匀，进而提高了混凝土管桩的结构强度。
