Description

Technical Field

[0001] The present invention relates to the field of concrete square pile production, and specifically to a concrete raw material mixer for producing concrete square piles. Background Art

[0002] Concrete square piles have high strength and high bearing capacity. Made of steel bars and concrete, precast concrete square piles have high strength and durability and can withstand large loads. Prestressed concrete solid square piles further improve the strength and bearing capacity of the pile body concrete by applying prestress. Concrete square piles can be mass-produced in factories or prefabricated on site, which makes the construction process more convenient and can ensure the construction quality. The quality of prefabricated parts is easy to control, reducing the uncertainty in on-site construction. Good durability and seismic performance: Concrete square piles have good durability and seismic performance, and are suitable for foundation projects in earthquake-prone areas and large basements. The shear resistance of hollow square piles is several times that of equivalent pipe piles, showing superior seismic performance. Save resources and costs: Concrete square piles can save wood and steel, and the cost is relatively low. At the same time, the construction period is short, which helps to reduce the overall project cost. In addition, the highly mechanized production process also reduces the instability caused by manual operation and improves production efficiency. Concrete square piles have been widely used in modern construction projects due to their high strength, high bearing capacity, convenient construction, good durability, resource and cost saving, strong adaptability, environmental protection and energy saving, etc. The existing concrete raw material mixers for the production of concrete square piles cannot dissipate heat well during mixing, which affects the life of the machine.
