Description
Technical Field
The invention relates to the technical field of assembled buildings, in particular to a method for adjusting the extending position of a grouting pipe for repairing a semi-grouting sleeve.
Background
In fabricated concrete structures, reliable connection of components is critical to ensuring structural safety. The steel bar sleeve grouting connection is a common steel bar connection form in an assembled concrete structure. In order to ensure that the effective anchoring length of the connecting steel bars meets the design requirement, the grouting material in the sleeve is fully filled. However, due to factors such as component machining precision and site construction level, leakage and less filling of slurry may occur in the sleeve. If the grouting inside the sleeve is not full, the grouting connection of the reinforced sleeve cannot reach the expected performance, and potential safety hazards are brought. How to repair and repair the grouting defects of the sleeve becomes a technical focus to be solved urgently in the current assembly type concrete structure, and the problem of the repair and repair of the grouting defects of the sleeve is urgently needed.
When repairing the grouting defect of the sleeve, the inside of the sleeve is always in a half-empty and half-full state, so that the single-hole repairing filling can only be carried out from the slurry outlet hole of the sleeve. The principle of single-hole filling from the grout outlet is that grouting material flows downwards along the grout filling gap between the inner wall of the sleeve and the connecting steel bars under the action of dead weight to fill the grouting defect, air in the grouting defect is discharged through the residual gap between the grout filling pipe and the grout outlet, and the grouting material overflows from the grout outlet after filling the whole grouting defect, so as to complete grouting. However, in the repair process of the filling, the phenomenon of early back flushing caused by that the slurry is not enough to flow downwards due to unreasonable utilization of the slurry filling gap and improper extending position of the slurry filling pipe often occurs, and the slurry overflows from the slurry outlet hole before filling, so that on-site constructors mistakenly fill the slurry, and the slurry filling is finished in advance, and finally the filling failure is caused.
To solve the above problems, a reasonable slurry compensating gap is first sought, and the slurry compensating gap is mainly determined by the relative position between the connecting steel bars in the sleeve and the inner wall of the sleeve. Because the repair of the filling is to carry out single-hole filling from the sleeve slurry outlet, the slurry filling pipe extends into the sleeve from the sleeve slurry outlet through the sleeve slurry outlet, and the relative position relationship between the connecting steel bar in the sleeve and the sleeve slurry outlet is particularly critical. Secondly, the position of the feeding pipe in the feeding gap is determined by the feeding position of the discharge end, and if the feeding position is not proper, even if a reasonable feeding gap is not fully utilized, the possibility of back flushing in advance still exists.
The grouting sleeve may be classified into a full grouting sleeve and a half grouting sleeve according to its form. The full grouting sleeve is a grouting sleeve with sleeve grouting mode for connecting steel bars at two ends of the cylinder, when the full grouting sleeve is used, the upper section steel bars in the sleeve are inserted in the process of manufacturing the component, the top of the sleeve is provided with a limit sealing ring with the thickness of about 20 mm, the upper section steel bars penetrate through the limit sealing ring and then are inserted into the sleeve, and the upper section steel bars basically have no deviation after being inserted. Therefore, the blocking object encountered by the slurry supplementing pipe after extending into the sleeve from the slurry outlet of the full grouting sleeve can only be the upper section of steel bars, the gap between the upper section of steel bars and the slurry outlet is relatively fixed, and the slurry supplementing pipe is usually 8-10 mm, so that the requirement of the slurry supplementing gap is completely met. The adjustment of the extending position of the slurry supplementing pipe is relatively easy to realize, and the slurry supplementing pipe can be firstly extended to prop against the upper section of steel bars and then is retracted backwards for 5-8 mm, so that the discharging end of the slurry supplementing pipe is positioned at a proper position.
The half grouting sleeve is a grouting sleeve with one end connected in sleeve grouting mode and the other end connected to steel bar in mechanical connection mode. Unlike a full grouting sleeve, the upper section of steel bars in a mechanical connection mode are not inserted into the inner cavity of the sleeve, and the lower section of steel bars are inserted into the inner cavity of the sleeve and determine the relative position relationship between the inner connection steel bars of the sleeve and the grout outlet of the sleeve. The design anchor (insert) length of the lower section steel bar is usually 8d, d is the diameter of the lower section steel bar, in an ideal state, based on reasonable design of the sleeve, the tail end of the lower section steel bar insert section is positioned close to the lower edge of the sleeve grout outlet, the positions are slightly different for different sleeve brands and sleeve specifications, but the tail ends of the connecting steel bars are basically positioned in the range of 5mm above and below the lower edge of the grout outlet. That is, the end of the lower section of reinforcing steel bar is not blocked from extending into the slurry compensating pipe in ideal condition. However, the lower section of steel bar is a mounting end, and the reserved steel bar at the top of the adjacent lower layer component is actually inserted into the half grouting sleeve at the bottom of the component, and due to the reasons of component manufacturing deviation, construction and mounting deviation, construction thickness deviation of joints at the bottom of the composite floor slab and the vertical component, and the like, when the lower section of steel bar is inserted into the inner cavity of the sleeve, the problems of deviation, inconsistent actual insertion length and design length and the like exist, so that the relative position relation between the sleeve grout outlet and the tail end of the lower section of connecting steel bar becomes complex working condition. The tail end of the lower section connecting steel bar is possibly higher than the sleeve grout outlet and possibly lower than the sleeve grout outlet, the lower section steel bar is possibly deviated close to the sleeve grout outlet and possibly deviated far away from the sleeve grout outlet, and even the sleeve grout outlet is completely blocked under two conditions simultaneously, so that no grout supplementing gap exists between the sleeve grout outlet and the lower section steel bar.
In summary, it is necessary to design a method for adjusting the insertion position of the grout pipe for repairing the grouting sleeve.
