Hollow prefabricated concrete pile and machining method thereof

Abstract

The invention relates to a hollow prefabricated concrete pile and a machining method thereof. The concrete pile comprises a pile body, a plurality of main ribs and a core pipe; the plurality of main ribs are arranged and bound into a reinforcement cage through spiral ribs; the distance between the main ribs and the outer surface of the pile body is 0-10mm larger than that of the existing standard; the main ribs are provided with pier heads and limited through end plates; the core pipe is connected with the reinforcement cage and then fixed to the center of the pile body; the core pipe is a hollow round pipe or a hollow square pipe; the two ends of the core pipe are closed; and the pile body is provided with a cavity with the section being round or square due to the core pipe. The machining method comprises the steps of concrete preparing, reinforcement cage manufacturing, core pipe installing, tensioning, pouring, steam curing and demolding. Compared with a hollow pile, the hollow prefabricated concrete pile can be used for corrosive geology, and the impact resistance of the end of the pile is improved during pile sinking; and compared with a solid pile, the usage amount of concrete is reduced, the weight of the concrete pile is reduced, cost is saved, transportation and construction are convenient, and meanwhile the difficulty of the manufacturing method is lowered.

Description

technical field [0001] The invention belongs to the field of concrete pile manufacture, and in particular relates to a hollow prefabricated concrete pile and a processing method thereof. Background technique [0002] Concrete piles have the advantages of saving wood and steel, durable, and low cost. They have been widely used in the foundation engineering of hydraulic construction, industrial construction, civil construction and bridges, and are also often used for anti-skid or isolation of slope and foundation pit support. water. [0003] At present, prefabricated concrete piles include hollow piles and solid piles. Compared with solid piles, the unit bearing capacity of hollow piles is lower. Due to its hollowness, shallow bearing layer and small diameter, the cost per unit bearing capacity is generally lower. Secondly, transportation, hoisting and pile sinking are convenient, and the construction speed is fast. However, for corrosive geology, the central hole of the ho...
