Concrete self-loading mixer trucks are more and more used in various engineering constructions, especially in small and medium-sized projects. Due to the advantages of the self-loading concrete mixer truck, it has a stronger ability to open up wasteland, and it can be used in places with narrow roads and rough roads.
Concrete self-loading mixer trucks have the following advantages in tunnel construction projects:
1. Efficiency: The self mixer directly loads the raw materials into the mixing drum for mixing, which reduces the steps and time of concrete preparation and improves the construction efficiency. During the mixing process, the vehicle can move at any time to adapt to the changing needs of the construction site, avoiding the midway transportation and waiting time of materials.
2. Quality control: The self-loading mixer truck is equipped with an automatic control system, which can precisely control the proportion of concrete and the mixing time. By monitoring and adjusting the ratio of cement, aggregate, mortar and water in real time, the uniformity and stability of concrete can be ensured and the quality of concrete can be improved.
3. Reduce waste of resources: Since the self-loading mixer truck mixes on site, the amount of concrete preparation can be adjusted according to actual needs, avoiding too much or too little waste. In addition, the mixing machinery equipped on the mixer truck can fully mix the materials, reducing the possibility of slurry separation and particle accumulation, and reducing material waste.
4. It can drive in both directions, easy to move, and can climb a slope of 30 degrees under full load.
In order to ensure the quality of concrete, the following measures can be taken:
1. Select suitable raw materials: ensure that cement, aggregate, mortar and other raw materials meet relevant standards and requirements, and have good quality and stability.
2. Implement strict quality control: During the mixing process, parameters such as the ratio of concrete, mixing time and mixing speed are monitored through the automatic control system, and timely adjustments and corrections are made to ensure stable quality of concrete.
3. Carry out sufficient tests and inspections: carry out necessary tests and inspections on raw materials and finished concrete, such as strength tests, impermeability tests, etc., and observe and evaluate the appearance and slump of concrete to ensure that the concrete meets the design requirements. Require.
4. Regular maintenance and maintenance: regular maintenance and maintenance of the pan mixer truck to ensure the normal operation of the mixing machinery and control system, as well as the accuracy of related instruments.
In general, the advantages of concrete self-loading mixer trucks are to improve construction efficiency, quality control and resource utilization. The quality of concrete in tunnel construction works can be ensured through strict quality control measures.
