Description
Technical field
The utility model belongs to the manufacturing technology field of high speed railway fragments-free track slab.More particularly, the utility model relates to a kind of bidirectional pre-tensioned prestressed concrete railway board long-surface pedestal production chain.
Background technology
Continuous development along with science and technology; There is tiny fragments of stone, coal, etc. track progressively to be eliminated because of its all drawback; And non-fragment orbit is because of its high reliability, high ride, high-durability and almost do not have characteristics such as track maintenance and in the construction of high-speed railway, progressively adopted, but the key technology of non-fragment orbit is track plate and manufacturing process thereof.
The track plate that is laid on above the roadbed bears the pressure from two rail because of it, along with the prolongation of time, often because of receiving external force deformation to cause that the phenomenon of crack or fracture appears in the track plate, therefore causes unnecessary loss.Simultaneously, safeguard also very inconvenience.For this reason, in the manufacture process of track plate,, and it is applied prestressing force, reduce the distortion that the track plate is caused by external force with this often to reinforcing bar or steel strand wires or rod iron or steel wire are set in the track plate.Applying of track slab prestress can be adopted pre-tensioning system and post stretching.In practical application, mostly existing track plate is post-tensioned prestressed concrete railway board, and its manufacturing process is very complicated, and production efficiency is low, and needs a large amount of ground tackles for the anchoring presstressed reinforcing steel.In addition; Current external various types of track plates all are arranged in prestressed steel bar on the kernel of section line; So must dispose the regular reinforcement cage in addition; Strengthen the intensity of track plate with this, this makes the cost of track plate increase greatly, and has brought in the upper and lower net sheet of steel reinforcement cage in length and breadth problem such as reinforcing bar insulation difficulty then.
Based on above reason, the scientific research personnel is carrying out unremitting effort always, and constantly seeks new, practical method to solve problems such as the concrete railway board manufacturing process is complicated, cost is high, track circuit is undesirable.Particularly; The present inventor has proposed a kind of bidirectional pre-tensioned prestressed concrete railway board and manufacturing process thereof respectively in one Chinese patent application No.200610017788.2 and one Chinese patent application No.201010136938.8, the full content in above-mentioned two patent applications combines in this application by reference.
Compare with common track plate of the prior art, above-mentioned bidirectional pre-tensioned prestressed concrete railway board has following feature and advantage:
(1) bidirectional pre-tensioned prestressed concrete railway board is symmetrically arranged in the both sides, cross section of track plate with the two dimension prestressing steel wire, can bear the multiple effect of cracking resistance, bending resistance and distributing bar simultaneously, and longitudinal reinforcement can also directly be used for vertical the couplet, and a muscle is used more.
(2) the vertical, horizontal steel wire of bidirectional pre-tensioned prestressed concrete railway board is in heavily stressed tensioned state, can keep the for example gap of 6mm, does not contact mutually.There is not any metallic closed loop in the track plate, on structural configuration, realizes insulation between the steel wire.
(3) the compressor wire cloth muscle of bidirectional pre-tensioned prestressed concrete railway board disperses, and the effective compressive pre-stress of concrete is more even, thereby has higher cracking resistance.
(4) because compressor wire is arranged in the natural axis both sides; Reduced the prestressing force eccentricity value of some pair cross-section with joint efforts; Simultaneously the steel wire arranged of both sides has certain inhibitory action to track slab warping distortion, thus bidirectional pre-tensioned pre-stress rail plate because of concrete shrinkage and creep or plate at the bottom of, the buckling deformation that produces of the plate face temperature difference is less.
(5) because bidirectional pre-tensioned prestressed concrete railway board steel content is lower; And no any metallic closed loop exists in the plate; The steel wire apart arrangement has good insulation, therefore need not add any insulation measures, can satisfy the track circuit demand of various signaling modes.
(6) bidirectional pre-tensioned prestressed concrete railway board structure has the high cracking resistance ability, is guaranteeing that the durability of pre-tensioned prestressed concrete track plate is fine under the condition that concrete batching, construction, maintenance require in strict conformity with durability concrete.
(7) owing to cancelled regular reinforcement cage, anchor plate and posttension ground tackle and saved insulation expense etc., compare with posttension track plate, the cost of bidirectional pre-tensioned prestressed concrete railway board is very cheap.
(8) bidirectional pre-tensioned prestressed concrete railway board is not only applicable to the spacing cell board of round boss, is applicable to the vertical spacing vertical yoke plate that joins yet.In addition, pre-tensioned prestressed concrete track plate can be used for cell board and vertical yoke plate, even the two ends of same block of track plate can adopt different limit methods, this for line get on the right track plate type selecting, arrange great flexibility be provided.
At present, a kind of technology that is used for the batch process of bidirectional pre-tensioned prestressed concrete railway board is the flowing water machine sets method production process.For example, the flowing water machine sets method production process that a kind of streamline that is suitable for above-mentioned bidirectional pre-tensioned prestressed concrete railway board is produced is disclosed among the aforementioned one Chinese patent application No.201010136938.8.In this technology, the pulling force that the prestressing force steel hinge line of the pulling force of the compressor wire that bear on steel model top and steel model bottom produces reaches equilibrium of forces through steel model under(-)chassis and template, and guarantees the flatness of product with this.Yet, in the long-term production practice, find that the prestressing force of steel model bottom is difficult to obtain effective monitoring and adjustment, so the flatness of product is difficult to guarantee.
Another kind of admissible track plate producing process is the long-line pedestal working system.Yet, need around steel model, all implement stretch-draw when producing and put Zhang Zuoye owing to bidirectional pre-tensioned prestressed concrete railway board, tensioning system that need be a large amount of, this causes the rapid rising of production line cost.And; Long-line pedestal method is along the unidirectional stretch-draw of pedestal direction; If use jack tension vertical direction reinforcing bar in its pedestal both sides, also can realize the production of existing product, but being exactly every mould, the problem that occurs needs one group of jack; Along with the increase of jack quantity, expense significantly rising, complicated operation, problem that effect is very low have been brought.In addition; With regard to high-speed railway developed country in the world; High-speed railway mainly adopts the I type track plate of Japan and the II type track plate of Germany in the world at present; Wherein the I type track plate of Japan adopts monolithic mould post stretching production technology, and the II template of Germany adopts unidirectional first Zhang Gong productions of planting, owing to bidirectional pre-tensioned prestressed concrete railway board is different fully with above two kinds of track intralamellar part structures; Therefore above two kinds of production technologies all can not simply be overlapped in the production of using the bidirectional pre-tensioned concrete railway board of prestressing force, can only be as a reference.And, up to now, do not find to have the precedent of producing bidirectional pre-tensioned concrete prefabricated element in batches as yet.
