Equipment and Characteristics of Concrete Delivery
In the process of concrete construction, the on-site transportation and pouring of concrete is a key work. For some large-scale reinforced concrete structures and high-rise buildings with a large amount of concrete, how to correctly select the concrete delivery tool and pouring method is even more important.
Concrete conveying equipment can be divided into the following types according to different usage scenarios and conveying methods:
Concrete pump: Concrete pump is a construction equipment that relies on pressure to transport concrete through pipelines. It can continuously complete horizontal and vertical transport at one time. Concrete pumps are divided into static pumps and concrete pump truck. The concrete pump truck is mainly composed of a pumping device and a motor vehicle. It is characterized by the use of a hydraulic system to transport concrete from the mixing station to the construction site through a pumping device. The pump truck has the characteristics of long distance, large hydraulic transmission capacity and high efficiency, and is suitable for large-scale projects.
Concrete mixer truck: Concrete mixer truck is a kind of equipment that integrates concrete mixing and conveying functions. Its main feature is the combination of mixing tank and conveying device, which can directly transport the mixed concrete to the construction site, and is suitable for small and medium-sized projects.
Hopper elevator: The hopper elevator adopts the bucket conveying method, and the motor drives the conveying chain or the conveyor belt to drive the hopper to move up and down, and conveys the concrete from the ground or the concrete mixing station to the designated position. The hopper elevator has the characteristics of simple structure and adjustable conveying distance, which is suitable for small projects.
Belt Conveyor: The conveyor belt is a commonly used concrete conveying equipment. The motor drives the conveyor belt to drive the concrete to flow on the conveyor belt and transport it from the mixing station to the construction site or other destinations. The conveyor belt has the characteristics of long conveying distance and large conveying capacity, and is suitable for long-distance and large-scale concrete conveying.
Cranes: Generally, tower cranes are used to periodically lift concrete hanging tanks, and at the same time, cranes also need to lift various building materials, components, and formwork; this method of transportation can directly distribute materials, but the cranes are too busy, and the efficiency is relatively high Low; cross-operation and reasonable arrangement of construction organization design are required.
Different types of concrete conveying equipment have their own characteristics and scope of application. When selecting and using, it is necessary to make a reasonable choice according to factors such as project scale, conveying distance, conveying volume, and construction conditions, manufacturer and pay attention to the maintenance and maintenance of the equipment to ensure its normal operation and conveying effect.
