Pipe jacking antifriction slurry and pouring device and pouring method thereof
The invention discloses pipe jacking antifriction slurry and a pouring device and a pouring method thereof.The pipe jacking antifriction slurry is composed of, by weight, 240-260 parts of bentonite, 800 parts of water, 200-220 parts of roe-shaped particles, 6 parts of sodium carbonate and 2.5 parts of a thickening agent, and the viscosity of the antifriction slurry is 60-61 parts. The roe-shaped particles comprise rigid plastic, stone powder and cement, the ratio of the rigid plastic to the stone powder to the cement is (2.5-3): 1: 1, the diameter of each roe-shaped particle is 2-3 mm, the density of each roe-shaped particle is 1.15 g/cm < 3 >, and the roe-shaped particles account for 18-22% of the total weight of the antifriction slurry; when the pipe jacking antifriction slurry and the pouring device and method thereof are used, pipe jacking friction can be reduced, the pipe joint advancing speed can be increased, the construction efficiency can be improved, the antifriction slurry is replaced by the cement slurry, soil deformation can be prevented while the overall strength is improved, and the pipe jacking antifriction slurry is suitable for application and popularization.
本发明公开了一种顶管减摩泥浆及其灌注装置和灌注方法，所述减摩泥浆由膨润土、水、鱼子状颗粒、纯碱和增稠剂组成，其中以重量份计数，膨润土占240‑260份，水占800份，鱼子状颗粒占200‑220份，纯碱6份，增稠剂占2.5份，所述减摩泥浆粘度为60‑61份，所述鱼子状颗粒包括硬质塑料、石粉和水泥，所述硬质塑料、石粉和水泥之间的比例为2.5‑3:1:1，所述鱼子状颗粒的直径为2‑3mm，密度为1.15g/cm³，鱼子状颗粒占减摩泥浆总重量的18‑22%；该顶管减摩泥浆及其灌注装置和灌注方法在使用时能够减小顶管摩擦，增大管节行进速度，提高施工效率，且水泥浆将减摩泥浆置换，增大整体强度的同时还能防止土体产生变形，适合推广使用。
