Abstract
The utility model discloses a kind of bridge prestress pipeline and mend sizing device, comprise precast beam body, it is characterized in that described precast beam body being equipped with vacuum mends sizing device, described vacuum is mended sizing device and is comprised vacuum pump, pre-buried pipeline, pipeline contiguous block, benefit slurry funnel, described benefit slurry funnel is connected with pipeline contiguous block by flexible pipe, and vacuum pump is connected with flexible pipe by three-way valve.The utility model reasonable in design, by the benefit sizing device arranged, benefit slurry is carried out in the cavity that precast beam body after can solidifying grouting occurs, through mending sizing device, the benefit sizing device in vacuum is set, be convenient to the gas in cavity to discharge, then carry out benefit slurry, improve grouting plumpness further, guarantee bridge prestress Structural Engineering quality, greatly improve the safe operating life of bridge.
Description
Technical field
The utility model belongs to construction engineering technical field, is specifically related to a kind of bridge prestress pipeline and mends sizing device.
Background technology
Flourish along with China's infrastructure facility, prestressed reinforced concrete construction is because of its significant technology economy advantage, and extensive use in the defeating completely of major works, towering, mammoth structure.Especially in the building of bridge, traditional bridge grouting is owing to adopting higher water-cement ratio, cause prestressed pore passage grouting bleeding, leakiness, form hole etc., thus cause prestress wire corrosion, cause post-tensioned prestressing structure engineering safety coefficient to reduce, once repeatedly occurred both at home and abroad because prestressed reinforcement corrosion causes bearing cross-section to amass the bridge collapse event of losing and causing.At present, not intensive problem is all there is in bridge in filling process, affect the safe operation of bridge, especially after grouting solidifies 3-4 days, slurries can flow to the both sides of precast beam body under gravity, the position of precast beam body highest point is caused to occur cavity, at present, in precast beam body filling process, be usually in the milk after coagulation after 3-4 days, just finish the grouting of this precast beam body, then effectively do not mend sizing device for the cavity of solidifying rear appearance.
Utility model content
For problems of the prior art, the purpose of this utility model is that design provides a kind of bridge prestress pipeline to mend sizing device.
Sizing device mended by described a kind of bridge prestress pipeline, comprise precast beam body, it is characterized in that described precast beam body being equipped with vacuum mends sizing device, described vacuum is mended sizing device and is comprised vacuum pump, pre-buried pipeline, pipeline contiguous block, benefit slurry funnel, described benefit slurry funnel is connected with pipeline contiguous block by flexible pipe.
Sizing device mended by described a kind of bridge prestress pipeline, it is characterized in that described pre-buried pipeline is arranged on the highest position of precast bridge.
Sizing device mended by described a kind of bridge prestress pipeline, it is characterized in that described pipeline contiguous block is hollow pipeline, and hollow pipeline two ends are arranged respectively at pre-buried pipeline and tube socket.
Sizing device mended by a kind of bridge prestress pipeline, and it is characterized in that described three-way valve leaks respectively at flexible pipe, benefit slurry and vacuum pump is connected, vacuum pump is connected with flexible pipe by three-way valve.
The utility model reasonable in design, by the benefit sizing device arranged, benefit slurry is carried out in the cavity that precast beam body after can solidifying grouting occurs, through mending sizing device, the benefit sizing device in vacuum is set, be convenient to the gas in cavity to discharge, then carry out benefit slurry, improve grouting plumpness further, guarantee bridge prestress Structural Engineering quality, greatly improve the safe operating life of bridge.
Accompanying drawing explanation
Fig. 1 is that the utility model mends sizing device structural representation;
In figure: 1-precast beam body, 2-vacuum mends sizing device, 3-vacuum pump, the pre-buried pipeline of 4-, 5-pipeline contiguous block, and 6-mends slurry funnel, 7-flexible pipe, 8-three-way valve.
Detailed description of the invention
The utility model is further illustrated below in conjunction with Figure of description.
As shown in Figure 1, sizing device mended by a kind of bridge prestress pipeline of the utility model, benefit slurry is carried out in cavity for solidifying rear appearance to the grouting of precast beam body, comprise precast beam body 1, precast beam body 1 is equipped with vacuum and mends sizing device 2, vacuum is mended sizing device 2 and is comprised vacuum pump 3, pre-buried pipeline 4, pipeline contiguous block 5, benefit slurry funnel 6, mended slurry funnel 6 and be connected with pipeline contiguous block 5 by flexible pipe 7, and vacuum pump 3 passes through three-way valve 8 and is connected with flexible pipe 7.Due in the process of solidifying again after grouting, slurries under gravity, can flow to precast beam body 1 both sides, the highest position of precast beam body 1 is caused to occur cavity, therefore, pre-buried pipeline is arranged on the highest position of precast bridge 1, the pipeline contiguous block 5 be connected with pre-buried pipeline 4 is hollow pipeline, hollow pipeline two ends are socketed with pre-buried pipeline 4 and flexible pipe 7 respectively and arrange, the concrete annexation of three-way valve 8 is, three-way valve 8 is respectively at flexible pipe 7, benefit slurry funnel 6 and vacuum pump 3 are connected, the volume of this benefit sizing device is arranged, be convenient to the tight ness rating improving grouting, plumpness.
Utility model works process is, pre-buried corrugated conduit, steel strand are installed stretch-draw, after grouting completes and solidifies 3-5 days, open vacuum pump 3, the cavity appearing at precast beam body 1 most significant end is vacuumized, after vacuumizing, carrying out benefit slurry by mending slurry funnel, continuing to vacuumize after mending slurry, guaranteeing the tight ness rating of being in the milk.
Mend slurry principle, find time need mend the air starching pipeline, foreign material, supplement prestress pipe special sizing agent enter and compacting pipeline after changeover switch by the principle of vacuum, protection prestress wire, prevents the generation of the problems such as steel strand corrosion, the safe operation of protection bridge.
