Described grout pipe goes out concrete component sectional position rubber ring is set one.Rubber ring is set and is convenient to after grouting, grout pipe be cut off from rubber washer bottom, the groove that utilizes rubber washer to form seals, and avoids shutoff post-grouting pipe to expose.
On described grout pipe, valve is set.In the time of concreting, closed, avoid concrete or other foreign material to enter grout pipe, cause line clogging and cannot use; In the time being in the milk, opening and be in the milk, in the time having multiple grout pipe on helical corrugation pipeline, while carrying out follow-up grouting by grouting pipeline valve closing above, avoid the backflow of slurry of being in the milk, can avoid waste, can make again front end sealing, more be conducive to the grouting of follow-up pipeline.
The upper foam-rubber cushion of pad between described arc pressuring plate and bellows.
The construction method of prestressed structure duct grouting device of the present invention, comprises the following steps,
(1) bellows is set to waveform, and each certain distance is established a high point;
(2) punching on height point, as grout hole;
(3) prefabricated arc pressuring plate is installed on the position of grout hole;
(4) grout pipe is arranged on the tube connector of arc pressuring plate, uses iron wire tighten;
(5) concreting, finishes after prestressed stretch-draw, is in the milk with being arranged on the high grout pipe of putting of bellows at the two ends in duct.
Grout pipe goes out concrete component sectional position rubber ring is set one, after grouting, grout pipe is cut off from rubber washer bottom, and the groove that utilizes rubber washer to form seals, and avoids shutoff post-grouting pipe to expose.
In the time of concreting by the valve closing being arranged on grout pipe, when grouting by the complete grouting pipeline valve closing that is in the milk above.
Adopt after such structure, built after concrete, on the grout pipe that is arranged on the high point of bellows, be in the milk, can segmentation be in the milk to bellows, the gas in bellows can be discharged smoothly, has avoided the discontented situation of being in the milk.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of prestressed structure duct grouting device of the present invention.
Fig. 2 is the sectional view along A-A line in Fig. 1.
Fig. 3 is the structural perspective of arc pressuring plate and grout pipe.
Detailed description of the invention
As shown in Figure 1 to Figure 3, prestressed structure duct grouting device of the present invention, comprise the bellows 2 being embedded in concrete 1, the waveform that is shaped as dipping and heaving of bellows 2, in the eminence of waveform bellows, grout hole 3 is set, prefabricated plastics arc pressuring plate 5 is installed on grout hole 3, radian and the caliber of arc pressuring plate 5 match, arc pressuring plate 5 is provided with the tube connector 6 mating with grout hole 3, grout pipe 4 is installed on tube connector 6, the upper foam-rubber cushion 7 of pad between arc pressuring plate 5 and bellows 2, obturages with adhesive tape in end.Grout pipe 4 exceeds concrete surface 8 and is not less than 300mm, closely knit in order to hole path pressure grouting.Tube sealing position is closely knit with foaming plugging.
Grout pipe is PPR material, goes out concrete surface 8 positions set up rubber ring 10 one at grout pipe, is convenient to after grouting, grout pipe 4 be cut off from rubber washer 10 bottoms, and the groove that utilizes rubber washer 10 to form seals, and avoids shutoff post-grouting pipe 4 to expose; Encapsulant can adopt than the grouting material of the high label of concrete and carry out shutoff.On grout pipe 4, set up 9 one of PPR Plastic valves, in the time of concreting, closed, avoid concrete or other foreign material to enter grout pipe 4, cause line clogging and cannot use; In the time being in the milk, opening and be in the milk, in the time having multiple grout pipe on helical corrugation pipeline, while carrying out follow-up grouting, grouting pipeline valve 10 is above closed, avoid the backflow of slurry of being in the milk, can avoid waste, can make again front end sealing, more be conducive to the grouting of follow-up pipeline; Valve 10 is same material material with grout pipe 4, and available hot melt connects.
