Description
Technical field
The utility model relates to a kind of post-tensioned prestressing beam overall process monitoring grouting system, overall process monitoring while being specially adapted to utilize rear tension prestress technology Construction Highway bridge, house reinforced concrete beam.
Background technology
Post-tensioned prestressing is widely used in industry and civilian construction, particularly longspan structure member.Post stressed concrete can be given full play to reinforcing bar and concrete characteristic separately, can improve rigidity, crack resistance and the durability of reinforced concrete member, can effectively utilize the concrete of high strength cast iron and high strength grade.Compared with ordinary concrete, under similarity condition, have that member section is little, good from heavy and light, quality, material economizes (can saving steel 40%～50%, concrete 20%～40%), and can expand the advantage of prefabrication and assembly construction degree.Grouting in post stretching technology refers to after tensioned prestressing bar by reserving hole to the process that pours into cement paste in duct.Cement paste can play protection presstressed reinforcing steel and do not corroded and strengthen the cementation between presstressed reinforcing steel and member, thereby filling process becomes the important control procedure of utilizing in the construction of post stretching technology.
Current prestressed grouting technique exists quality control on construction, and mainly such as, by existing in workman's experience and professional personal integrity (grouting pressure, screen slurry time, grouting quantity), filling process, uncertain factor is more, in seriously lagging behind, constructing, cannot find timely and effectively that without directly management means, existing management method quality problems, construction note exist the problems such as artificial modifications in construction, thereby develops development and the popularization to post-tensioned prestressing technology of grouting method that a kind of overall process monitors and be significant.
Summary of the invention
Be difficult to the shortcoming guaranteeing in order to overcome in existing post-tensioned prestressing filling process because of artificial subjective factor and more the caused grouting quality of uncertain factor, the utility model provides a kind of post-tensioned prestressing overall process monitoring grouting system, this monitoring grouting system, for full weight, compactness and the intensity of prestressed structure grouting provide safeguard measure, can improve the total quality of prestressed structure construction.
The technical solution adopted in the utility model is:
Post-tensioned prestressing beam overall process monitoring grouting system, comprise grouting equipment, described grouting equipment is tightly connected by high pressure grouting pipeline and by the one end in presstressed reinforcing steel duct reserved in construction concrete beam beam body, the other end in described presstressed reinforcing steel duct is connected with high pressure grouting seal for pipe joints, the two ends in described presstressed reinforcing steel duct form two cement mortar matter anchor plates, it is characterized in that: the one end in described presstressed reinforcing steel duct is stock inlet, the other end is grout outlet, install and be provided with the first pressure sensor and flow meter at described stock inlet, install and be provided with the second pressure sensor at described grout outlet, the first described pressure sensor is connected with flow meter, described flow meter is connected with grouting equipment, the first described pressure sensor, flow meter is arranged between stock inlet and grouting equipment, and the first described pressure sensor, the second pressure sensor and flow meter are connected with a recorder respectively.
Further, described recorder comprises data acquisition controller and display screen, and described the first pressure sensor, the second pressure sensor and flow meter are connected with described data acquisition controller respectively, and described data acquisition controller is connected with display screen.
Further, described flow meter is electrically connected with a power supply.
Further, on described high pressure grouting pipeline, ball valve is installed.
The utility model is in filling process, and grouting stock inlet and grout outlet pressure, the instant flow that is in the milk directly read in by sensor, and by cable, data signal are inputted to recorder, is recorded and is directly shown on recorder display screen by recorder.Administrative staff can directly observe on-the-spot True Data, have avoided adopting the error that visually observes existence, have also reduced management workload.Recorder is by the record to the instant flow that is in the milk and gather, can obtain the total flow of grouting in phases-time and the total flow of being in the milk in rear duct, and recorder can record the total flow in each duct by number by setting operation, administrative staff can directly transfer recorder internal record and check every grouting parameter in each duct, stop at the scene few filling and leak the phenomenon of filling with in construction.The operation of screen slurry is the critical process in grouting construction, in the utility model, the operation of screen slurry will directly be monitored by grouting stock inlet and grout outlet pressure sensor, and directly record the screen slurry duration by recorder, screen slurry force value and the record of duration complete by recorder completely, administrative staff can directly monitor or indirect call recorder data, check implementation status and the implementation effect of this operation, guaranteed implementation dynamics and the implementation result of working procedure.
The beneficial effects of the utility model are embodied in: by the overall process monitoring to filling process, the construction quality of controlled grouting and grouting time exactly, the engineering real data of grouting each time can be recorded and preserves again, for the later control of grouting construction and the development of grouting technique provide strong engineering practical basis.
