When using an automatic loading mixer truck to load concrete, the rotation speed of the mixing drum is 2-10 rpm. During transportation, ensure that the speed of the mixing tank on the horizontal road is 2-3 rpm. If the slope is greater than 50, when the road is uneven or shakes violently, stop mixing and spinning, and wait for the road to improve before mixing and spinning.

The quality of the tunnel depends on the quality of the process. The quality of the process depends on the quality of the excavation, initial support and drainage and drainage, etc. The better control of the initial support and drainage and drainage can strengthen supervision, so the focus is on the quality of the excavation, which depends on the quality of the excavation The quality of drilling and blasting means that in theory, the quality of the initial support without over-excavation

1. The operating lever is convenient for operation, and the touch screen adds water quantitatively.

2. The operation is sensitive and convenient, and the quantitative addition of water on the touch screen makes the stirring more uniform and more in line with the specifications.

The horizontal cement tank is a new type of cement silo designed by our factory to be matched with the mobile batching plant. This cement silo adopts a slow-pressure structure, which can effectively place the cement arching phenomenon, and at the same time cooperate with a special flow-assisting device to achieve a uniform cement speed. Material is not compacted during long-term storage, hidden dust collector to ensure that there is no dust.

Concrete slump mainly refers to the plasticizing performance and pump ability of concrete. The factors that affect the concrete slump mainly include gradation change, water content, weighing deviation of the scale, and the amount of admixture, which are easily overlooked. Cement temperature, etc. Slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including the water retention, fluidity and cohesion of concrete.

(1) When the concrete strength level is less than C50, the slump should be less than 180 mm, and when the strength level is greater than C50, the slump should be greater than 180 mm; (2) When the specified concrete slump is less than 40 mm, the allowable deviation is ±10 Mm; when the specified concrete slump is 50~90 mm, the allowable deviation is ±20 mm; when the specified concrete slump is greater than 100 mm, the allowable deviation is ±30 mm;

Concrete refers to a general term for engineering composite materials in which aggregates are cemented together by cementitious materials, and is widely used in civil engineering. Because it consists of solid phase, liquid phase, and gas phase, some bubbles will inevitably be produced after the concrete is poured. But the existence of these bubbles will not only affect the appearance of the project, but more importantly, it will have some hidden risks.

For the treatment measures of concrete bubbles, select the appropriate vibrating equipment, and determine the appropriate vibrating time, vibrating radius and frequency. At the same time, vibrate according to the method of "fast insertion, slow pumping, up and down drawing", the vibrating rod should be straight up Quickly insert and pull slowly, no leakage is allowed. When vibrating, it should twitch up and down.

When the average day and night temperature is lower than 5 ℃ or the low temperature is lower than -3 ℃, it should be treated as winter construction. When the ambient temperature is lower than 5 ℃, it is forbidden to sprinkle the concrete surface for curing. At this time, the curing liquid can be sprayed on the concrete surface, and appropriate heat preservation measures should be taken.
