1.根据工地距离及施工部位,充分发挥车载GPS的作用,安装混凝土企业管理控制系统,以便合理安排混凝土搅拌车的运输线路及发车间隔,确保混凝土浇筑既不会中断也不因此造成车辆等待时间过长。
1. According to the distance between the construction site and the construction site, give full play to the role of vehicle GPS, and install the concrete enterprise management and control system, so as to reasonably arrange the transportation route and departure interval of the concrete mixer truck, so as to ensure that the concrete pouring will not be interrupted and the waiting time of vehicles will not be too long.
2.质检部门应根据实际情况在配方中添加缓凝剂,以便增加混凝土的初凝时间,使混凝土在运输到更远的地方时仍保有相应的质量,从而减少混凝土凝结在罐体和叶片上的机会。
2. The quality inspection department should add retarder to the formula according to the actual situation, so as to increase the initial setting time of concrete, and keep the corresponding quality when the concrete is transported to a farther place, so as to reduce the chance of concrete setting on the tank body and blade.
3.施工方应优先确保塔吊用于斗车的吊送,混凝土搅拌站应尽量减少每车混凝土的运输量,从而控制卸料时间在1h之内,并严格保证搅拌车罐体的正常转动,不得随意停止转动,这样就能大大减少混凝土粘罐情况的发生。

3. The construction party should give priority to ensure that tower crane is used for the lifting of bucket car. The concrete mixing station should try to reduce the concrete transportation volume of each truck, so as to control the unloading time within 1h, and strictly ensure the normal rotation of the mixing truck tank body, and do not stop rotating at will, so as to greatly reduce the occurrence of concrete tank sticking.
4.夏季施工尽量避开中午前后的高温时段,改在清晨或晚上施工,以避免环境高温对混凝土的影响,尽量将车停放在阴凉的地方,必要时可采取给搅拌筒浇水降温、穿车衣隔热等方法。
4. The construction in summer should avoid the high temperature period around noon as far as possible, and change the construction in the morning or at night to avoid the impact of high temperature on the concrete, park the vehicle in a cool place as far as possible, and if necessary, water the mixing drum to cool down, wear car clothing for heat insulation and other methods.
5.驾驶员在搅拌车运输途中及在工地等待卸料过程中应保持搅拌筒正转,以搅动混凝土,在卸料完毕后,应及时加水及碎石到搅拌筒内搅拌,回场后立即清洗并卸掉,以除去粘附的混凝土。维修人员应定期检查拌筒内叶片的磨损情况,尽量按原样修复磨损及变形的叶片,必要时请生产厂家协助修复。
5. The driver shall keep the mixing drum in a positive rotation to stir the concrete during the transportation of the mixer truck and in the process of waiting for unloading at the construction site. After unloading, the driver shall add water and gravel to the mixing drum for mixing, and clean and unload the concrete immediately after returning to the site to remove the adhered concrete. The maintenance personnel should regularly check the wear of the blades in the mixing drum, try to repair the worn and deformed blades as the original, and ask the manufacturer to assist in the repair if necessary.
6.后是,搅拌车研究机构及生产厂家应对传统的搅拌车搅拌系统进行深入科学的研究,采用新的搅拌系统设计思想,优化改进传统搅拌筒的外形、搅拌叶片的母线、搅拌叶片的安装形式等等,使混凝土在搅拌后的坍落度相对比较均匀,出料速度、出料残余率等性能指标得到更好的改进,从根本上减少混凝土在罐体和叶片上的粘结。
6. After that, the research institutions and manufacturers of mixer should conduct in-depth and scientific research on the traditional mixing system, adopt the new mixing system design idea, optimize and improve the shape of the traditional mixing drum, the generatrix of the mixing blades, the installation form of the mixing blades, etc., so as to make the slump of the concrete relatively uniform after mixing, the discharging speed, the discharge residual rate and other performance The index has been improved, and the adhesion of concrete on the tank and blade can be reduced fundamentally.
