specific Embodiment approach

[0016] A method for pumping concrete to pour thin-walled steel pipe centrifugal concrete pipe piles; it includes a concrete mixer and a thin-walled steel pipe with one end closed, and the pouring method also includes a concrete delivery pump truck and a platform truck and a steel pipe mounted on it Molded pouring trolley, and implemented in accordance with the following steps:

[0017] A. Select the corresponding concrete mixer according to the concrete design requirements of the pipe pile structure to mix the desired ratio of concrete materials;

[0018] B. Select concrete with fixed pump according to production capacity, pile type and concrete strength

[0019] C. Place the thin-walled steel pipe horizontally on the steel mold of the platform truck, and move the platform truck so that the conveying steel pipe enters the inner cavity from the open end of the thin-walled steel pipe;

[0020] D. Enter the concrete that meets the requirements after mixing into the delivery pump...

Abstract

The invention relates to the concrete thin wall steel tube centrifugal tube plug. It comprises the concrete blender, one end sealed thin wall steel tube, a casting table cart, blending the concrete material, selecting delivery pump car with output connected to a delivery pipe, setting the thin wall steel tube on the table cart to send steel tube to the inner cavity, blended concrete delivered to the thin wall steel tube inner cavity through the steel tube pump, casting the table car according to the casting direction of the concrete, till the opening of the steel tube to stop the delivery pumpcar, to the centrifugal forming of the thin wall steel tube. It is reduced in labor, and improved in efficiency.

Description

technical field [0001] The invention relates to a method for making steel pipe piles for piling in the construction field, in particular to a method for pumping concrete to pour thin-walled steel pipe centrifugal concrete pipe piles. Background technique [0002] At present, many industrial and civil buildings in coastal areas choose super-long steel pipe piles as their foundations. Due to the large amount of pile foundation and the large sideways movement caused by the excavation of the foundation pit, if the method of driving steel pipe piles into concrete is used for reinforcement, the steel pipe must ensure sufficient wall thickness, otherwise it will be damaged during drilling. When entering the steel pipe, the steel pipe yields due to excessive hammering force. At the same time pouring concrete on site will also bring inconvenience to the construction and increase the cost. Therefore, people consider pouring concrete in steel pipes and then centrifugally forming thin...
