Problems solved by technology

[0004] 1. The production of centrifugal precast concrete pipe piles and hollow square piles requires concrete centrifugal forming equipment, which requires large investment, complicated manufacturing process, and difficult control of pile quality
Limited by the process method, a pile of one specification can only correspond to one formwork, and the utilization efficiency of the formwork is low
[0005] 2. For the production of centrifugal precast concrete pipe piles and hollow square piles, at most two piles can only be stretched together, which is less efficient
[0006] 3. The existing precast concrete square piles, precast concrete rectangular piles, prestressed precast concrete square piles, and prestresse

Example Embodiment

[0029] Embodiment 1: A manufacturing method of prestressed concrete precast piles, which includes the following steps:

[0030] 1. Concrete production (conventional process): build a concrete mixing station and prepare concrete according to the technical requirements of precast concrete piles;

[0031] 2. Pile-body reinforcement cage production (conventional process): Reinforcement lashing and welding reinforcement cages are made according to the design and technical requirements of precast concrete reinforcement cages. Reinforcement cages can be manufactured in batches by manual lashing and mechanical seam welding;

[0032] 3. Construction of steam curing pool and tensioning platform:

[0033] (1) The steam curing tank is composed of several steam curing units (see figure 1 , figure 2 ), each steaming unit includes steaming pond bottom 1, steaming pond bottom 1 is connected to steaming pond wall 2, steaming pond bottom 1 is evenly distributed with counter beams 3, steaming pond wall ...

Example Embodiment

[0047] Embodiment 2: A method for manufacturing non-prestressed concrete precast piles, which includes the following steps:

[0048] 1. Concrete production (conventional process): build a concrete mixing station and prepare concrete according to the technical requirements of precast concrete piles;

[0049] 2. Pile-body reinforcement cage production (conventional process): Reinforcement is made according to the design and technical requirements of precast concrete reinforcement cages, and lashed and welded reinforcement cages. Reinforcement cages can be manufactured in batches by manual lashing, mechanical roll welding, etc.;

[0050] 3. Construction of steam curing pool:

[0051] The steam curing tank is composed of several steam curing units (see figure 1 , figure 2 ), each steaming unit includes steaming pond bottom 1, steaming pond bottom 1 is connected to steaming pond wall 2, steaming pond bottom 1 is evenly distributed with counter beams 3, steaming pond wall 2 is equipped with...

Abstract

The invention relates to a manufacturing method of a concrete precast pile, comprising the following steps of: concrete manufacturing; pile body steel reinforcement cage manufacturing; steam curing pool constructing; pile template preparing and erecting; steel reinforcement cage lifting and mold entering; prestress steel reinforcement cage stretching and drawing; template finishing; concrete casting, vibrating and surface finishing; steam curing; pile body concrete quality inspecting; pile lifting demolding; and template finishing correcting; the manufacturing method is characterized in that a steam curing pool consists of a steam pool bottom, a steam pool wall, an upstanding beam, a steam pool cover, a catch pit and a steam pipeline; a bottom template is paved on the upstanding beam of the steam pool bottom, a side template is vertically paved on one side of the bottom template, and the templates are erected in a sequence of a side template, a bottom template, a side template and a bottom template; and the manufacturing method has the characteristics of being suitable for large-scale industrialized production, good in universality of production technology, little in productive investment, high in efficiency, good in product quality, and the like.

Description

[0001] Technical field: [0002] The invention relates to a method for manufacturing a concrete prefabricated pile, which belongs to the technical field of building materials. Background technique: [0003] At present, the existing precast concrete piles are: precast concrete square pile, precast concrete rectangular pile, prestressed precast concrete square pile, prestressed precast concrete rectangular pile, centrifugal prestressed concrete pipe pile, centrifugal prestressed concrete hollow square pile Wait. The industrial method of its production has the following disadvantages: [0004] 1. The production of centrifugal precast concrete pipe piles and hollow square piles requires concrete centrifugal forming equipment, which requires large investment, complicated manufacturing process, and difficult control of pile quality. Limited by the process method, a pile of one specification can only correspond to one formwork, and the formwork utilization efficiency is low. [...
