Abstract

The invention relates to a method for producing a centrifugal concrete pipe pile. Concrete is placed into a depiler; and a reinforcement cage and end plates at the two ends of the reinforcement cage are assembled into a whole and then placed into a lower semi-mould which is cleaned up and coated with a separant. The method is characterized by also comprising the following steps of: after combining the upper semi-mould and the lower semi-mould which are cleaned up and coated with the separant, stretching the mould; hanging and placing the stretched mould on a distributing trolley, and moving the distributing trolley and pumping the concrete into the mould through a delivery pump at the same time; and performing centrifugal molding, curing, removing the mould, cleaning, and finally coating the separant. The method has the advantages of improving degree of mechanization, reducing the labor intensity, increasing the production efficiency, improving the integrity and the durability of a pile head of the pipe pile, along with no dripping of the concrete, no leakage at commissure, smooth appearance, and contribution to improving the product quality.

Description

A kind of production method of centrifugal concrete pipe pile

Technical field

The present invention relates to the production method of centrifugal concrete pipe pile.

Background technology

Existing pile tube production craft step is:

1, yellow ground, stone, cement, additive and water are stirred by reasonable proportioning, form concrete;

2, the concrete that stirs is put into depiler, prepare stand-by;

3, spiral bar and PC rod iron are weaved into steel reinforcement cage through automatic seam welder, make reinforcing bar form skeleton;

4, after being assembled into one, the end plate at two ends and steel reinforcement cage put into the lower mold half of cleaning out and coat interleaving agent;

5, the lower mold half that will be placed with steel reinforcement cage hangs on the cloth chassis, then the concrete in the depiler is put into material distributing machine by the needed amount of preparing on the chassis to produce of pile tube;

6, on one side mould on the chassis is put into the concrete in the material distributing machine in mobile trolley used one side;

7, after the coagulation handwoven cloth is finished, the concrete of shedding of mould both sides is cleaned out;

8, the upper mold half that will clean out and scribble interleaving agent hang and the lower mold half of cloth honest material close;

9, the mould that is folded carries out stretch-draw;

10, the mould that stretch-draw is good is placed on and carries out centrifugal forming on the centrifuge;

11, the stake after the forming is put into the maintenance pond and is carried out maintenance;

12, maintenance is carried out form removal after reaching design strength;

13, torn that mould is cleared up and to coat interleaving agent stand-by open, put into the stockyard splitting out the stake that comes.

The defective that above production technology exists is:

1, concrete is shed during cloth, and the cleaning mould is caused difficulty, and is time-consuming, reduces production efficiency.

2, be difficult to clean out when the cleaning die orifice, cause the joint close spillage when centrifugal, the product quality qualification rate is low.

3, because first cloth post-stretching, because of stretching extension causes spiral bar and PC rod iron solder joint sealing-off, particularly stretch-draw end movement maximum, sealing-off is serious, so pile crown often breaks during piling construction.

4, time-consuming because of cloth, usually the employee much concentrates on the zonule of cloth, the normal security incident that takes place in the production.

Summary of the invention

The object of the invention is to propose a kind of production method of the pump concrete formula centrifugal concrete pipe pile that reduces productive labor intensity, raises the efficiency, improves the quality of products.

Processing step of the present invention comprises: concrete is put into depiler, put into the lower mold half of cleaning out and coat interleaving agent after the end plate at framework of steel reinforcement and two ends is assembled into one, carry out stretch-draw after it is characterized in that to clean out and to scribble the upper mold half of interleaving agent and lower mold half matched moulds, to hang through the mould of stretch-draw on the cloth chassis then, the moving cloth chassis pumps into concrete in the mould through delivery pump on one side on one side, through centrifugal forming, maintenance, form removal, cleaning, coat interleaving agent at last again.

Advantage of the present invention:

1, the present invention is because of adopting the concrete pump pump concrete, and the thing that does not have concrete to shed takes place, and has improved mechanization degree, and the minimizing personnel enhance productivity, and have solved and have produced the low problem of pile tube process efficiency in the past.

2, because the die orifice of mould is a matched moulds when not having concrete, no longer include the problem of joint close spillage, smooth in appearance can reduce the labour intensity of trimming.

3, because of the technology of placing concrete behind the employing pretensioning,, can improve the integrality and the durable resistance of tubular pile head, be beneficial to the raising of product quality so the elongation of stretch-draw can not cause spiral bar and PC rod iron solder joint sealing-off phenomenon.

4,, can reduce personnel, reduce labour intensity, the security that can improve production process greatly because of mechanization degree height of the present invention.

The specific embodiment

The pile tube production craft step:

2, the concrete that stirs is put into depiler, prepare stand-by;

5, the upper mold half that will clean out and scribble interleaving agent hangs and lower mold half is closed;

6, the mould that is folded carries out stretch-draw;

7, the good mould of stretch-draw is hung be placed on the cloth chassis, simultaneously the concrete in the depiler is put into concrete pump by the required concrete of preparing on the chassis to produce of pile tube;

8, on one side mobile trolley used one side pumps into the concrete pump inner concrete in the mould on the chassis;

9, the good concrete mould of pump is placed on and carries out centrifugal forming on the centrifuge;

10, the stake after the forming is put into the maintenance pond and is carried out maintenance;

11, maintenance is carried out form removal after reaching design strength;

12, torn that mould is cleared up and to coat interleaving agent stand-by open, put into the stockyard splitting out the stake that comes.

Claims

1. the production method of a centrifugal concrete pipe pile, comprise: concrete is put into depiler, put into the lower mold half of cleaning out and coat interleaving agent after the end plate at framework of steel reinforcement and two ends is assembled into one, carry out stretch-draw after it is characterized in that to clean out and to scribble the upper mold half of interleaving agent and lower mold half matched moulds, to hang through the mould of stretch-draw on the cloth chassis then, the moving cloth chassis pumps into concrete in the mould through delivery pump on one side on one side, through centrifugal forming, maintenance, form removal, cleaning, coat interleaving agent at last again.
