Do you know the purpose of highway construction machinery and equipment?

I believe many of our friends have built roads in front of their homes. Do you know the purpose of highway construction machinery and equipment? Today we will talk about the configuration and combination of mechanical equipment.

I. Reasonably allocate construction machinery

Selection method of construction machinery

(1) Select machinery according to the work content

(2) select machinery according to construction conditions

(3) Select construction machinery according to the quantities

(4) quantity of construction machinery

2、 Allocation of main mechanical equipment for subgrade works

(1) For earth excavation works, the selected machinery and equipment mainly include bulldozers, excavators, scrapers, loaders and dump trucks.

(2) For rock excavation works, the selected machinery and equipment mainly include bulldozers, excavators, mobile air compressors, rock drills, blasting equipment, etc.

(3) For earth rock filling works, the selected machinery and equipment mainly include bulldozer, scraper, sheep foot roller, roller, sprinkler, grader and dump truck.

3、 Allocation of main mechanical equipment for cement concrete pavement construction

It mainly includes concrete mixing plant, loader, transport vehicle, excavator, crane, slip form paver, leveling beam, roughening and vitality maintenance, joint cutting machine, sprinkler, etc.

4、 Configure according to the construction method (sliding mode paving construction)

(1) The capacity of cement concrete mixing plant shall meet the requirements of 1m/min construction speed of slip form paver;

(2) large slip form pavers with a width of 7.5 ~ 12.5m should be selected for the construction of high-grade highways;

(3) for long-distance transportation, concrete tanks should be used for delivery;

(4) It can be equipped with a wheel excavator to assist with the cloth.

5、 Configuration of main machinery for tunnel engineering construction

(1) Drilling machinery: pneumatic rock drill, hydraulic rock drill, rock drilling jumbo;

(2) Charging trolley;

(3) top finding and bottom cleaning machinery;

(4) primary support machinery: anchor rod trolley and concrete sprayer;

(5) Grouting machinery (including drilling machine and grouting pump);

(6) Slag loading machinery;

(7) transportation machinery (including dump trucks and mining trucks);

(8) Secondary support and lining machinery: formwork lining trolley (concrete mixing station, mixing truck, concrete delivery pump).
