Abstract
The invention relates to a protection method for a conducting wire of an embedded instrument, which comprises the following steps: first, vertically inserting a steel bar into the exporting position of the conducting wire of a reinforcing cage, binding the steel bar together with the reinforcing cage, and sleeving a corrugated tube onto the steel bar; and then, outputting the conducting wire out of the reinforcing cage along the steel bar and winding the conducting wire around the steel bar. According to the invention, a groove is formed in the bottom of the corrugated tube, the corrugated tube is clamped in the steel bar of the reinforcing cage through the groove; and the width of the groove at the bottom of the corrugated tube is the diameter of the steel bar of the reinforcing cage, and the depth of the groove is 10-15 mm. Due to the adoption of the protection method, the conducting wire of the instrument can be effectively protected to be in a safe and sound state during the construction process, which ensures the safety output of the data and lays the foundation of data accuracy. The protection method has the advantages of simplicity and convenience in material obtaining, and wide application, and barely has any influence on construction.
Description
Technical field
The present invention relates to the guard method of flush type instrument lead in a kind of building operations.
Background technology
Along with the development of bridge cause, Prestressed Concrete Bridges is used widely, and the Prestressed Concrete Bridges of different bridge-types is in continuous construction, and span progressively strengthens, and also to the light-duty development of thin-walled, unsafe factor increases structure thereupon in the cantilever construction.Especially in construction operating mode, the sunshine temperature difference, concrete shrinkage, creep, under the multiple external cause combined influence such as prestressed stretch-draw, the stress state of bridge is in continuous change and progress, yet how can guarantee in the whole process of construction that the precision of Stress Control and accuracy are a great problems in the surveying work always.
Owing to the construction plant circumstance complication, guarantee the accuracy of data, to protect the integrality of instrument at first exactly, therefore this safeguard measure is proposed, effectively protected the safety of instrument, be not subjected to the influence of construction factor.
Summary of the invention
The present invention is the safety that will solve flush type instrument lead in the building operations, is not subjected to construction environment and destroys, and causes the technical problem of data acquisition failure, and a kind of guard method of flush type instrument lead is provided.
For solving the problems of the technologies described above; technical scheme of the present invention is: a kind of guard method of flush type instrument lead; at first a steel bar vertical is inserted the reinforcing cage lead and derive the position; and with the reinforcing cage colligation together; above reinforcing bar, be inserted in bellows again; lead is derived from reinforcing cage along reinforcing bar then, and is wound on the reinforcing bar.
The bellows bottom slot, bellows snaps in the reinforcing cage reinforcing bar by the groove on it; Bellows bottom slot width is the reinforcing cage bar diameter, and groove depth is 10mm ~ 15mm.
The invention has the beneficial effects as follows:
(1) derives lead with vertical reinforcement, can fix lead preferably, be convenient to the daily management of data acquisition and instrument.
(2) owing to the polishing concrete surface, the destruction that bellows has protected lead not to be subjected to lateral force, the safety of assurance lead.
Description of drawings
Fig. 1 is that vertical reinforcement of the present invention is arranged sectional drawing;
Fig. 2 is the stereogram of bellows;
Fig. 3 is vertical reinforcement and bellows combination section.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.
The guard method of flush type instrument lead of the present invention comprises:
(1) determine instrument lead burial place after, can adopt method of the present invention in nigh position.
(2) insert reinforcing cage 1 with vertical reinforcement 2 earlier, firm with reinforcing cage 1 colligation, draw reinforcing cage 1 by vertical reinforcement 2.
(3) put bellows 3 on the vertical reinforcement 2, and by the fluting 4 of bellows 3 bottoms bellows 3 and reinforcing cage 1 reinforcing bar are fixed together.
Wherein: bellows 3 bottom slots 4 width are reinforcing cage 1 bar diameter, and 4 degree of depth of slotting are 10mm ~ 15mm, are as the criterion can snap in reinforcing cage 1 reinforcing bar fully.
The flush type instrument generally be embedded in concrete or with the reinforcing cage colligation at instrument recording data such as stress, temperature, therefore have lead to draw, so that instrument is exported data by lead.By the combination with bellows and reinforcing bar; the take measures safety of guardwire; tie up on reinforcing cage reinforcing bar is endways; be used for lead is twined around it; height will surpass concrete surface; consider the concrete surface of in the future will polishing, thus be enclosed within on the reinforcing bar with bellows again, can be by transversely cutting with guardwire.Because bellows can not well be fixed, thus a little grooves will be opened in bellows one side, in order to can be stuck on the reinforcing cage.
Claims (3)
1. the guard method of a flush type instrument lead; it is characterized in that: at first a reinforcing bar (2) is vertically inserted reinforcing cage (1) lead and derive the position; and with reinforcing cage (1) colligation together; be inserted in bellows (3) in reinforcing bar (1) top again; lead is derived from reinforcing cage (1) along reinforcing bar (2) then, and is wound on the reinforcing bar (2).
2. the guard method of flush type instrument lead according to claim 1 is characterized in that: described bellows (3) bottom slot (4), bellows (3) snaps in reinforcing cage (1) reinforcing bar by the groove on it (4).
