Description

A kind of prestressing force prefabricated pile production technology

Technical field

The present invention relates to a kind of tubular pole manufacturing process, especially a kind of prestressing force prefabricated pile production technology.

Background technique

With the development of concrete technology, the technology of concrete tubular pile also reaches its maturity, except applied to industry, civil buildings Outside, it is also widely used for each field such as bridge, harbour, railway or hydraulic engineering, tubular pole is by strength grade of concrete and wall thickness point For prestressed concrete pipe pile (PC tubular pole), thin tubular piles produced by prestressed concrete (PTC tubular pole) and prestressed high-strength coagulation Native tubular pole (PHC tubular pole), also whether there is or not pile for prestressed pipe, such as thin wall steel tube concrete tubular pole (TSC tubular pole)；It is general pre- Stress prefabricated pile production technology, it is no or not reasonable to the recycling design with material, and it is unfavorable for the guarantor of environment Shield.

Summary of the invention

Technical problem to be solved by the present invention lies in provide a kind of prestressing force prefabricated pile production technology.

In order to solve the above-mentioned prior art problems, the present invention uses a kind of following scheme: prestressing force prefabricated pile production technology, The step are as follows:

Step S1: carrying out fixed length cutting processing to PC rod iron first, then carries out pier nose to the end of the PC rod iron after cutting Processing, the then cold-drawn good PC rod iron of pier nose again, finally by these PC rod iron roll weldings at steel reinforcement cage；

Step S2: after steel cage and end plate, mold cooperation, the concrete for measuring and stirring by facilities of mix storied building being distributed in mold, It after being post-processed using tensioning, will be put into centrifuge after mold, by certain parameter of noncentricity centrifugal forming；

Step S3: the mold after the completion of being centrifuged is put into steam-cured pond and carries out steam-cured processing, and steam-cured processing includes that normal pressure is steam-cured and steam pressure Maintenance；

Step S4: becoming steam for water after the burning of compressed biomass shaped granule in boiler, is sent into steam-cured pond maintenance stake；

Step S5: after stake maintenance reaches demoulding tonicity, so that it may which demoulding is put into warehouse for finished product stacking after detection is qualified.

Preferably, material source needed for making concrete: passing through jaw by the bulk stone of outsourcing in the S2 step Formula crusher is crushed after being broken into fritter stone, cleaning by conical breaker, and sand material and stone are made after vibrating screen sieves Material, the sand material of outsourcing and the sand material, the building stones that process are cleaned clean rear as raw material, and the waste water that sand, stone cleaning generate is through sinking Fine sand process is back to behind the pond of shallow lake.

Preferably, bulky grain sinking speed is most fast in the S2 step, it is settled down to outermost layer first, cement mortar is filled out It fills in the gap between bulky grain, forms closely knit concrete layer, remaining cement mortar and part of cement net slurry are deposited on system Product inner wall, forms screed and net slurry layer, extra moisture are extruded.

Preferably, normal pressure is steam-cured to be divided into 4 stages in the S3 step: it is quiet stop, heat up, constant temperature and cooling, normal pressure steams Supporting the time is 10 hours, and steam press maintenance is divided into 3 stages: heating, constant temperature and cooling, the time of steam press maintenance is about 10 ~ 12 hours.

The utility model has the advantages that

Present invention employs above-mentioned technical proposals to provide a kind of prestressing force prefabricated pile production technology, compensates for the prior art not Foot, design rationally, can be salvaged, energy saving, protect environment.

Detailed description of the invention

Fig. 1 is process flow chart of the invention.

Fig. 2 is technique for producing raw material flow chart of the present invention.

Specific embodiment

As shown in Figure 1, a kind of prestressing force prefabricated pile production technology, it is characterised in that the step are as follows:

Step S1: carrying out fixed length cutting processing to PC rod iron first, then carries out pier nose to the end of the PC rod iron after cutting Processing, the then cold-drawn good PC rod iron of pier nose again, finally by these PC rod iron roll weldings at steel reinforcement cage, step S2: steel cage After end plate, mold cooperation, the concrete for measuring and stirring by facilities of mix storied building is distributed in mold, is post-processed using tensioning Afterwards, it will be put into centrifuge after mold, by certain parameter of noncentricity centrifugal forming, in centrifugal process, bulky grain sinking speed It is most fast, it is settled down to outermost layer first, cement mortar is filled in the gap between bulky grain, forms closely knit concrete layer, remaining Cement mortar and part of cement net slurry be deposited on product inner wall, form screed and net slurry layer, extra moisture be extruded, walk Rapid S3: the mold after the completion of being centrifuged is put into steam-cured pond and carries out steam-cured processing, and steam-cured processing includes that normal pressure is steam-cured and steam press maintenance, In the S3 step, normal pressure is steam-cured to be divided into 4 stages: it is quiet stop, heat up, constant temperature and cooling, the normal pressure steam-cured time is 10 hours, And steam press maintenance is divided into 3 stages: heating, constant temperature and cooling, the time of steam press maintenance are about 10 ~ 12 hours, steam press maintenance work The task of sequence is exactly scientifically and rationally to send out the hydro-thermal reaction of inside concrete sufficiently using the wet heat condition of steam press maintenance It waves, achievees the purpose that make concrete that there is some strength, while obtaining some strength, be effectively prevented from supported in steam pressure again What shield was likely to occur in the process is unfavorable for hydro-thermal reaction or has the case where damage maintenance effect and quality of item, step S4: boiler Water is become into steam after middle compressed biomass shaped granule burning, be sent into steam-cured pond maintenance stake, step S5: stake maintenance reaches de- After mould tonicity, so that it may which demoulding is put into warehouse for finished product stacking after detection is qualified.

As shown in Fig. 2, being technique for producing raw material flow chart of the present invention, material source needed for making concrete: by outsourcing Bulk stone it is broken by conical breaker after jaw crusher is broken into fritter stone, cleaning, by Vibration Screen Be made sand material and building stones after point, the sand material of outsourcing and the sand material, the building stones that process it is cleaned it is clean after be used as raw material, wherein sand, The waste water that stone cleaning generates is back to fine sand process after sedimentation basin, discharge of wastewater is not fallen, and waste water is carried out again It utilizes, saving material can be played the role of, protect environment.

Those skilled in the art can make various modifications to described specific embodiment Or supplement or be substituted in a similar manner, however, it does not deviate from the spirit of the invention or surmounts the appended claims determines The range of justice.
