Abstract
The invention discloses a production method of a concrete pipe pile. The method sequentially comprises the following steps of: (A) loading cage ribs required for producing a pipe pile into a mould, then closing an upper mould and a lower mould and tightening screws; (B) conveying a prepared concrete material into the cavity of the mould; (C) stretching the cage ribs in the mould and applying prestress; and (D) hanging the mould onto a centrifugal machine for centrifuging and molding. The method aims to overcome the defects in the prior art and provide a production method of a concrete pipe pile having simple process, convenient processing, relatively lower cost, stable product quality and higher production efficiency.
Description
Technical field
The present invention relates to the production method of concrete tubular pile.
Background technology
In the prior art, producing the concrete tubular pile order generally is to adopt dress steel reinforcement cage, cloth concrete material, matched moulds, post-stretching, centrifugal forming more earlier.The concrete tubular pile that the method is produced mainly contains following defective:
1, quality aspect: the concrete tubular pile of producing commissure spillage, joint close occur than phenomenons such as broads, causes pile tube the time to batter down easily and influence its useful life in construction simultaneously;
2, equipment aspect: when punching block carries out matched moulds, be difficult to close tight, cause between the upper and lower mould running wheel gap bigger, thereby cause punching block when centrifugal, to beat, damage punching block and centrifuge because of concrete particle drops;
3, secure context: drop because of concrete particle is arranged, the wind gunner hinders hand when the matched moulds of punching block is cleared up easily, has great potential safety hazard;
4, required labour aspect: because of when the concrete distributing, have a large amount of particles to drop, need personnel in time clear up and insert and smash, per tour needs 4～6 people to clear up the concrete particle that these drop, waste of manpower at least;
5, auxiliary material aspect:, need a large amount of spades and besom because concrete particle is scattered on flatcar and the ground easily when concrete carries out cloth;
Summary of the invention
The objective of the invention is provides a kind of technology simple, easy to process in order to overcome weak point of the prior art, relatively low, the constant product quality of cost, the production method of the concrete tubular pile that production efficiency is higher.
In order to achieve the above object, the present invention adopts following scheme:
The production method of concrete tubular pile may further comprise the steps successively:
A, will produce the needed cage muscle of pile tube and pack into behind the mould, the upper and lower mould that closes tightens the screw;
B, pre-assigned concrete material is transported to dies cavity;
C, the cage muscle in the above-mentioned mould is carried out stretch-draw, apply prestressing force;
D, mould is hung centrifugal forming on centrifuge.
The production method of aforesaid concrete tubular pile, it is characterized in that adopting among the step C stretch-draw machine that the cage muscle in the mould is carried out stretch-draw, concrete operation is that the cage muscle with the pipe die head end is fixed on the stretch-draw machine with ground tackle, open the stretch-draw machine, the 0.5-0.8 that regulates stretch-draw intensity and be cage muscle overall strength doubly, stretch-draw 10-60 second;
The production method of aforesaid concrete tubular pile is characterized in that stretch-draw intensity among the step C is 0.7 times of cage muscle overall strength
In sum, beneficial effect of the present invention:
One, quality assurance
Because the concrete tubular pile that the method is produced is to adopt first matched moulds, tightens the screw earlier, closes tightlyer between the upper and lower mould, has solved the problem of concrete tubular pile joint close spillage, thereby has ensured the pile tube quality.
Two, equipment fault reduces
Because of what adopt is first matched moulds, and the gap is less between the upper and lower mould, and beating when centrifugal has not had, and the wearing and tearing of punching block and centrifuge running wheel reduce, impaired the reducing of bearing of centrifuge.Thereby reduced equipment failure rate, improved production efficiency and reduced the maintenance of equipment expense.
Three, reduced the labour
Because what adopt is first matched moulds, the direct cloth of concrete is to the inner chamber of punching block, and the existing picture that does not exist concrete particle to drop has reduced cleaning mould limit and smash personnel with slotting, thereby reduced recruitment, saves the work people.
Four, reduce production costs
Because of what adopt is first matched moulds, need not spades and instrument such as besom, reduced production cost.
