1. Unreasonable discharge residual rate and blade design. From the internal structure of the mixing drum, the mixing drum of the concrete mixer truck relies on the rotating drum to drive the spiral motion generated by the two spiral blades, so that the concrete can obtain both "tangential" and "axial" composite motion, so that the mixing drum has the functions of mixing and unloading. Therefore, the relevant factors forming this spiral motion, such as the curve parameters of the spiral blades, The geometry and size of the mixing drum have an important impact on the discharge residual rate of the mixing truck. The excessive unloading residual rate means that there will be more surplus materials in the mixing tank after unloading, so it is more likely to stick materials in the mixing tank over time.
2.运输间隔太长。跟着都会化的历程及都会计划的请求，愈来愈多的搅拌站被请求迁到郊区和郊县，与郊区的间隔愈来愈远，而因为混凝土这一产物的出格性，任何预拌混凝土在未增加缓凝剂的环境下，都在1h摆布进入初凝状况，若是这时候候才遏制混凝土浇注施工，岂但影响混凝土的工程品质，并且因混凝土落空活动性，易在搅拌筒及叶片上固结，致使粘罐，严峻时乃至整车混凝土粘在罐内及构成液压装备的破坏，以是打鱼注册送分 保送预拌混凝土有当时候节制的保送半径，普通应节制在1h之内。
2. The transportation distance is too long. With the process of urbanization and the requirements of urban planning, more and more mixing plants are required to move to suburbs and suburban counties, which are farther and farther away from the urban area. Due to the particularity of concrete, any ready mixed concrete will enter the initial setting state from left to right within 1h without adding retarder. If the concrete pouring construction is carried out at this time, It not only affects the engineering quality of concrete, but also because the concrete loses fluidity, it is easy to condense on the mixing drum and blades, resulting in tank sticking. In serious cases, even the whole vehicle concrete sticks in the tank and causes damage to hydraulic equipment. Therefore, the transportation radius of ready mixed concrete by concrete mixer truck is controlled within 1h.
3.工地施工设想分歧理。工地在墙柱等施工中，会用塔吊吊斗车的方式遏制浇捣，因为塔吊的料原来塌落度就比泵送的低，更因为施工时候长，卸一车混凝土凡是要2~4h，有些驾驶员为了省油而遏制搅拌筒的普通动弹，这类环境下，出格轻易构成粘罐，偶然9方车一次粘罐就达1t，在炎天环境更严峻。
3. Unreasonable site construction design. During the construction of walls and columns on the construction site, the tower crane bucket truck will be used for pouring and tamping. Because the slump of the tower crane is lower than that of the pump, and because the construction time is long, it usually takes 2 ~ 4H to unload a truck of concrete. Some drivers stop the normal rotation of the mixing drum in order to save oil. In this case, it is particularly easy to cause tank sticking. Sometimes the tank sticking of the 9-square truck can reach 1t at a time, The situation is more serious in summer.
4.利用掩护不妥。打鱼注册送分 驾驶员在打金鱼 卸料终了后未实时清算洗濯搅拌罐内及叶片上残留的混凝土，在打金鱼 回站历程中不动弹搅拌罐，残留的混凝土枯燥后固结在拌筒及叶片上，今后就会越聚越多，构成粘罐景象。
4. Improper use and maintenance. The driver of the concrete mixer truck fails to clean the residual concrete in the mixing tank and on the blades in time after the unloading of the mixer truck. During the return of the mixer truck to the station, the mixing tank does not rotate. The residual concrete will solidify on the mixing drum and blades after drying, and will gather more and more in the future, forming the phenomenon of tank sticking.
5.打鱼注册送分 任务环境温度太高。夏日在南边地域白天午时前后，环境温度常常跨越30℃，在这类环境下运输混凝土，将会因为混凝土坍落度丧失快和罐体四周温度绝对中间更高，是以混凝土更轻易粘罐。
5. The working environment temperature of concrete mixer is too high. In summer, the ambient temperature often exceeds 30 ℃ around noon in the South during the day. In this case, when transporting concrete, it will be easier for the concrete to stick to the tank due to the rapid loss of concrete slump and the higher temperature around the tank relative to the center.
