How is the design code of concrete mixing station specified?

A, must set up the mixing station of highway engineering, highway engineering concrete mixing budget can only be budgeted by mixer.

Highway engineering must set up mixing station.

A mixing station and a mobile mixing station must be set up for highway projects with large concrete quantities, long construction period and concentrated construction.

(b) The concrete mixing budget of highway engineering can only be budgeted by mixers.

In the budget, there is no separate item in the highway quota, it is all included in the concrete, that is, the budget is based on the mixer.

Second, the concrete mixing station

(1) Definition

The concrete mixing station is mainly composed of five systems, namely, mixing host, material weighing system, material conveying system, material storage system and control system, and other ancillary facilities. Compared with station aggregate measurement, building aggregate measurement reduces four intermediate links, and it is vertical blanking measurement, which saves measurement time and greatly improves production efficiency. In the same mode, the production efficiency of the mixing plant is increased by one third compared with that of the mixing plant. For example, the production efficiency of HLS90 building is equivalent to that of HZS 120 station, and that of HLS 120 building is equivalent to that of HZS 180 station, and that of HLS 180 building is equivalent to that of HZS240 station.

② Function

Concrete mixing station is a combined device for centralized mixing of concrete, also known as concrete prefabrication yard. Because of its high degree of mechanization and automation, its productivity is also high, and it can ensure the quality of concrete and save cement. It is often used in large and medium-sized water conservancy, electric power, bridges and other projects with large concrete quantities, long construction period and concentrated construction sites. With the development of municipal construction, the mixing station with centralized mixing and providing commercial concrete has great advantages, so it develops rapidly, which creates conditions for popularizing concrete pumping construction and realizing the joint operation of mixing, conveying and pouring machinery.
