Abstract
The invention relates to a production method of a heavy-load concrete turnout tie. The method comprises the following steps: A, placing a bottom plate in a mold to fix and strengthening the mold; B, cleaning the mold and spraying a release agent; C, arranging embedded parts in the mold in a combined mode of arranging an embedded iron seat and an embedded bushing; D, feeding reinforcing steel bars in the mold and tensioning; E, injecting concrete in the mold and performing vibratory molding; F, lifting the mold after molding in a curing pool and introducing steam to cure; G, demolding when required compressive strength is required and performing moisture curing after demolding. By using the production method, the mold is strengthened, so that the tension value can be improved; by arranging the embedded parts in the combined mode of arranging the embedded iron seat and the embedded bushing, the purpose of improving the load can be achieved.
Description
Technical field
The present invention relates to a kind of production method of heavily loaded concrete switch sleeper.
Background technology
At present, the production method of heavily loaded concrete switch sleeper is subject to mould stretch-draw value and the restriction of built-in fitting mode is installed, and can only produce the heavily loaded concrete switch sleeper of carrying 50kg/m, 60kg/m, and for the production of the heavily loaded concrete switch sleeper of 75kg/m, helpless.
Summary of the invention
The production method that the purpose of this invention is to provide a kind of heavily loaded concrete switch sleeper that can improve bearing capacity.
The technical scheme that the present invention takes is: a kind of production method of heavily loaded concrete switch sleeper is characterized in that it comprises the following steps: A, that base plate is put into to model is fixing, and model is carried out to consolidation process; B, model is cleaned out to rear spraying releasing agent; C, the mode combined by installation preburied iron base and service sleeve are installed built-in fitting in mould; D, reinforcing bar enter mould and carry out stretch-draw; E, inject concrete vibrating forming in mould; F, the model of forming is hung in to curing pool pass into steam curing; G, the demoulding when reaching needed compression strength, carry out moisture-keeping maintaining and get final product after the demoulding.
Adopt the present invention, because of model is carried out to consolidation process, can promote the stretch-draw value, and by the mode that preburied iron base and service sleeve combine is installed, built-in fitting is installed, just can realize the purpose of raising bearing capacity.
The specific embodiment
Below in conjunction with specific embodiment, invention is described further.It comprises the following steps:
1, base plate is put into to model according to rational arrangement mode fixing, guarantee that base plate is concordant with the face of model, and model is carried out to consolidation process;
2, after model is cleaned out, the spraying releasing agent, releasing agent will spray evenly;
3, the mode combined by installation preburied iron base and service sleeve is installed built-in fitting in mould;
4, reinforcing bar enters mould and carries out stretch-draw, and the stretch-draw value is 705kN ± 5kN;
5, the concrete of the C60 that mixes is injected in model, and vibrating forming, concrete compaction guaranteed;
6, after the clear groove in clear limit, the model of forming is hung in to curing pool and pass into steam curing;
7, carry out the demoulding during compression strength more than reaching needed 45MPa, after the demoulding, moisture-keeping maintaining is 3 days, and product can be used after product inspection is qualified.
