Large steel bridge support grouting material and grouting method thereof
The invention discloses a large steel bridge support grouting material and a grouting method thereof, and relates to the field of support grouting materials, the large steel bridge support grouting material comprises the following raw materials by weight: 95-105 parts of a cementing material, 95-105 parts of graded river sand, 0.2-0.3 part of a polycarboxylic acid water reducer, 0.04-0.06 part of a plastic expanding agent, 0.06-0.10 part of a powder defoaming agent, 1-2 parts of a viscosity reducer, and 0.02-0.06 part of a stabilizer; grouting material dry powder is prepared from the raw materials; the cementing material is prepared from PII52.5 cement, silica fume, superfine mineral powder and an expanding agent according to the following proportion: the ratio of the PII52.5 cement to the silica fume to the superfine mineral powder to the expanding agent is 75: (6 to 10): (6 to 12): (7 to 12). Therefore, the problem that high-quality installation of the support cannot be completed through a traditional bridge support grouting material and a conventional pouring process is solved, the grouting material has excellent performance, and the dense and flat support padstone without surface blistering and cracking can be obtained through the pouring process.
本申请公开了一种大型钢桥梁支座灌浆料及其灌注方法，涉及支座灌浆料领域，按重量分数计包括如下原料：胶凝材料95～105份，级配河砂95～105份，聚羧酸减水剂0.2～0.3份，塑性膨胀剂0.04～0.06份，粉体消泡剂0.06～0.10份，降粘剂1～2份，稳定剂0.02～0.06份；由以上原料制成灌浆料干粉；所述胶凝材料由PII52.5水泥、硅灰、超细矿粉、膨胀剂按以下比例组成，PII52.5水泥：硅灰：超细矿粉：膨胀剂＝(75：6～10：6～12：7～12)。借此，解决了传统桥梁支座灌浆料和常规灌注工艺无法完成该支座的优质安装的问题，不仅灌浆料具有优异性能，而且通过该灌注工艺可以获得密实、平整、无表面起泡、不开裂的支座垫石。
