1. How about the self loading mixer at the construction site?

　　施工现场应具备混凝土标准试件制作条件，并应设置标准试件养护室或养护箱。标 准试件养护应符合现行有关标准的规定。地下室底层和上部结构首层柱、墙混凝土 带模养护时间，不宜少于3d；带模养护结束后可采用洒水养护方式继续养护，必要 时也可采用覆盖养护或喷涂养护剂养护方式继续养护；其他部位柱、墙混凝土可采 用洒水养护；必要时，也可采用覆盖养护或喷涂养护剂养护。不得在其上踩踏、堆 放荷载、安装模板及支架。

　　The construction site shall have the conditions for making standard concrete specimens, and the curing room or curing box for standard specimens shall be set up. The curing of standard specimens should be in accordance with the current relevant standards. The curing time of column and wall concrete with formwork at the basement bottom and the first floor of superstructure should not be less than 3D; after the curing with formwork, it can be continued by spraying water, or by covering or spraying curing agent when necessary; the column and wall concrete in other parts can be recycled Spray water for curing; if necessary, cover curing or spraying curing agent can also be used. It is not allowed to step on it, stack loads, install formwork and support.

　　2.自上料搅拌车如何处理紧急驱动

　　2. How to deal with emergency drive of self feeding mixer

　　将自上料混凝土搅拌车熄火,将其液压马达的高压油管卸下,并与故障车上的对应接头用紧急驱动软管相连。发动搅拌车,将其操纵手柄拨出料位置,故障车内的混凝土即被排出，准备好紧急驱动软管,将搅拌车熄火,卸下液压马达上的高压油管接头。

　　Turn off the self loading concrete mixer, remove the high-pressure oil pipe of its hydraulic motor, and connect it with the corresponding joint on the fault truck with emergency drive hose. Start the mixer, turn the control handle to the discharging position, and the concrete in the fault truck will be discharged. Prepare the emergency drive hose, turn off the mixer, and remove the high-pressure oil pipe joint on the hydraulic motor.
             

　　将发动机熄火，拆松液压马达的一根高压油管,搅拌筒可自由旋转，控制搅拌筒的旋转,使维修孔转到下部,然后打开维修孔，清理出筒内混凝土，在托轮和滚道之间放入木楔,以控制搅拌筒的旋转，一定要注意。

　　Turn off the engine and loosen a high-pressure oil pipe of the hydraulic motor. The mixing drum can rotate freely. Control the rotation of the mixing drum to make the maintenance hole turn to the lower part. Then open the maintenance hole to clean out the concrete in the cylinder. Put a wooden wedge between the supporting roller and the raceway to control the rotation of the mixing drum. Pay attention to safety.

　　3.自上料搅拌车两个防止

　　3. Two prevention measures from feeding mixer

　　防止发动机爆燃夏季气温高，有时超过35°C，而在这样的季节，对于部分老化部件的汽车，自然爆炸的概率也要高得多。所以要做好预防准备。

　　To prevent the engine from deflagration, the temperature is high in summer, sometimes exceeding 35 ° C. in such a season, the probability of natural explosion is much higher for vehicles with some aging parts. So be prepared for prevention.

　　防止发动机机体过热由于环境温度较高，发动机容易过热。有必要加强发动机冷却系统的检查和维护。这包括检查水箱，恒温器，水泵，风机等，并注意及时添加。注意冷却水。当水温超过100°C时，停在阴凉处冷却，让发动机怠速，并打开引擎盖以帮助散热。

　　To prevent the engine block from overheating, the engine is easy to overheat due to the high ambient temperature. It is necessary to strengthen the inspection and maintenance of engine cooling system. This includes checking the water tank, thermostat, water pump, fan, etc., and paying attention to timely adding. Pay attention to the cooling water. When the water temperature exceeds 100 ° C, stop in the shade to cool, let the engine idle, and open the hood to help heat dissipation.
