Abstract
A filling nozzle used for grouting comprises a tube, the tube is provided with a first screw thread segment and a vertical injection hole, a spacing steel ring is arranged on the tube, the first screw thread segment is provided with an extruding nut, and at least one elastic sealing ring is arranged between the extruding nut and the spacing steel ring. A plurality of elastic sealing rings and gaskets are arranged between the extruding nut and the spacing steel ring in an interlaced manner. When the filling nozzle used for grouting adopting the above structure is used, the extruding nut is compacted to deform the elastic sealing ring having a rubber material in order to tightly combine a nozzle and the grouting hole, so a pressure slurry is pressed into a concrete slab in order to improve the strength of the substrate of a road concrete slag. A bent steel joint is connected with a high-pressure rubber tube, so the connection direction of the bent nozzle and the high-pressure rubber tube substantially reduces the break possibility of the high-pressure rubber tube. The filling nozzle used for grouting is easy to dismount, and improves the construction efficiency.
Description
Technical field
The present invention relates to the concrete grouting field, particularly a kind of filling mouth for grouting.
Background technology
The road of construction is cement concrete pavement mostly before several years, and these road surfaces use a period of time to transform owing to maintenance difficult, roadability are relatively poor.For reducing engineering cost, reduce waste simultaneously to environment damage, taked the former cement-concrete road of suitable repairing during most of road reformation engineering design after, directly brush the black mode of handling at cement concrete pavement.
In existing road reformation engineering, it is an important link that hollow plate is handled, and design adopts the high pressure grouting method to handle usually.Sealing between the concrete slab of high pressure grouting pipeline and road and the performance of connected mode directly influence grouting quality and efficient.Be difficult to combine closely between existing high pressure grouting nozzle and the grout hole, adopt mounting or dismounting inconvenience after other shutoff or the seal approach.Be vertical direction between existing high pressure grouting nozzle and the high-pressure rubber hose, the weight that rubber tube bears slurries during normal construction bends, and often fractures.
Summary of the invention
Technical problem to be solved by this invention provides a kind of filling mouth for grouting, high pressure grouting pipeline and road cement concrete slab sealingly can be coupled together, the pressure slurries are pressed under the concrete slab, reach the purpose that improves road concrete plate substrate intensity.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of filling mouth for grouting, comprise body, body is provided with first thread segment and vertical injected hole, body is provided with spacing steel ring, the extruding nut is installed on first thread segment, is provided with at least one elastic seal ring between extruding nut and the spacing steel ring.
Between extruding nut and spacing steel ring, a plurality of elastic seal rings and packing ring interlaced arrangement.
Described elastic seal ring is two or more.
Described extruding nut one side also is provided with movable steel ring.
Described body is connected with steel elbow type joint by first thread segment.
Described spacing steel ring is connected with body by spacing thread segment.
Also be provided with the nut handle on the described extruding nut.
Also be provided with at least one side injected hole on the body.
A kind of filling mouth for grouting provided by the invention, by adopting above-mentioned structure, compress the elastic seal ring distortion that the extruding nut makes the rubber material during use, thereby combination closely between nozzle and the grout hole, be convenient to the pressure slurries are pressed under the concrete slab, reach the purpose that improves road concrete plate substrate intensity.By being connected with high-pressure rubber hose behind the steel elbow type joint, the closure of bending nozzle and high-pressure rubber hose greatly reduces the possibility that high-pressure rubber hose fractures.The present invention is easy to dismounting, has improved efficiency of construction.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is overall structure schematic diagram of the present invention.
Among the figure: steel elbow type joint 1, the first thread segment 2, side injected hole 3, vertical injected hole 4, nut handle 5, extruding nut 6, movable steel ring 7, the first packing rings 8, the first elastic seal rings 9, second packing ring 10, second elastic seal ring, 11, the three packing rings 12, spacing steel ring 13, spacing thread segment 14, body 15.
The specific embodiment
In Fig. 1, a kind of filling mouth for grouting comprises body 15, and body 15 is provided with first thread segment 2 and vertical injected hole 4, also is provided with at least one side injected hole 3 on the body 15.
In the scheme of optimizing, a plurality of elastic seal rings and packing ring interlaced arrangement between extruding nut 6 and the spacing steel ring 13.In this example, elastic seal ring adopts two.
Further in the scheme of optimizing, described extruding nut 6 one sides also are provided with movable steel ring 7.In Fig. 1, set gradually movable steel ring 7, first packing ring 8, first elastic seal ring 9, second packing ring 10, second elastic seal ring 11 and the 3rd packing ring 12 in extruding nut 6 one sides, be that spacing steel ring 13 is spacing then, wherein spacing steel ring 13 is connected with body 15 by spacing thread segment 14.Stress raisers were damaged elastic seal ring when such structure can be used for preventing from pushing.Normal conditions lower limit steel ring 13 is fixedly mounted on the spacing thread segment 14, only just uses when changing packing ring and elastic seal ring.Packing ring adopts plastic material in this example.In this example, described elastic seal ring is two, but according to the length of grout hole or the requirement of sealing, also can adopt more structures.
Described body 15 is connected with steel elbow type joint 1 by first thread segment 2.Even be connected with high-pressure rubber hose by steel elbow type joint 1, for delivery of the pressure slurries.
Also be provided with nut handle 5 on the described extruding nut 6.
During grouting, after concrete slab is accomplished fluently grout hole, high-pressure rubber hose and steel elbow type joint 1 are connected, insert in the grout hole irritating mouth, in Fig. 1, rotating nut handle 5, thus tighten extruding nut 6, and extruding nut 6 moves to right, right pressure activity steel ring 7, and then first packing ring 8 is moved to right, thereby vertical when first elastic seal ring 9 is pushed become big, the hole wall of extruded concrete grout hole to the right, seal, second packing ring 10 also pushes to the right thereupon and makes second elastic seal ring, 11 vertical changes greatly, the hole wall of while extruded concrete grout hole, a further sealing function.
When changing the hole, backward rotation nut handle 5 unclamps extruding nut 6, because the retraction effect of first elastic seal ring 9 and 11 two rubber rings of second elastic seal ring, has reduced the friction with the grout hole hole wall, irritates mouth, the grouting that enters next hole again thereby transfer to.
