Abstract
A non-return type grouting nozzle comprises a nozzle body, a steel ball and an inserted pin. An inlet hole and an outlet hole are formed in the nozzle body and adopt a through hole, and the aperture of the outlet hole is larger than that of the inlet hole. An inserted pin is arranged on one side of the outlet hole of the nozzle body, and is embedded on a drilling hole of the nozzle body wall, and a steel ball is arranged in the outlet hole inside the inserted pin. The diameter of the steel ball is larger than the aperture of the inlet hole; and the diameter of the steel ball is smaller than the aperture of the outlet hole. The non-return type grouting nozzle can guarantee project quality and safeguard personnel safety and enhance work efficiency, and can be widely applied to various types of slurries, such as chemical grouting slurry and cement grouting slurry.
Description
Technical field
The utility model relates to a kind of grout nipple, the engineering processing that particularly is related to antiseep or improves supporting capacity, and for leak stopping or increase the concrete structure crack treatment of building stability performance, and during the grouting method that adopts, the inverse-stopping type grout nipple that on grouting equipment, is provided with.
Background technology
For antiseep or improve supporting capacity and for leak stopping or increase the concrete structure crack treatment of building stability performance, in the time of must taking grouting method to handle, in grouting equipment, grout nipple in the past only works to connect sebific duct.In filling process, after being full of slurries in the crack, the grouting sebific duct must be extracted from the mouth mouth, being the slurries that pressure condition is arranged in the crack this moment will spray thereupon, the ejection of slurries has not only influenced workmanship, and cause personal injury (slurries that have are toxic) easily, traditional method of preventing and treating is, after extracting sebific duct from the mouth mouth, use immediately with the bore waddy and insert the mouth mouth, after slurries solidify in waiting crack, waddy could be extracted (generally must 24 hours), therefore traditional method affect workmanship and dangerous, efficient is low, not scientific and reasonable.
Summary of the invention
The technical problems to be solved in the utility model is, provide a kind of in the concrete structure crack in the filling process, after being full of slurries in the crack, to be in the milk sebific duct when the mouth mouth is extracted, can block the slurries ejection automatically, and make slurries bonding more closely and solidify with the concrete of periphery or rock in the crack, improve workmanship and safety, efficient height, scientific and reasonable inverse-stopping type grout nipple.
The technical scheme that adopts is:
The inverse-stopping type grout nipple comprises mouth body, steel ball and latch.In the described mouth body steel ball is set, steel ball size is greater than mouth body import department diameter, and less than mouth body exit diameter, steel ball is stopped and can not be dropped out by the latch that is arranged on the mouth wall, and when grouting, slurries enter in the crack by space between steel ball and mouth wall.After being full of slurries in the crack, extract sebific duct from the mouth mouth, be slurries that pressure condition is arranged this moment in the crack steel ball is pushed up import department to the mouth body, block slurries ejections (seeing Fig. 1, Fig. 2).
Above-mentioned steel ball size is greater than the aperture less than mouth body cutout hole, the aperture of mouth body inlet hole.
The utility model can guarantee workmanship, guarantees personal safety and increase work efficiency, and can be widely used in all types of slurries, as chemical grouting slurries, cementation slurries etc.

The specific embodiment
The inverse-stopping type grout nipple comprises mouth body 1, steel ball 2 and latch 3.Establish inlet hole 4 and outlet opening 5 in the described mouth body 1, and inlet hole 4 is a through hole with outlet opening 5, the aperture of outlet opening 5 is greater than the aperture of inlet hole 4.Outlet opening one side of mouth body 1 is provided with latch 3, and latch 3 is embedded in the boring of mouth body wall, and steel ball 2 is arranged in the outlet opening 5 of latch 3 inboards, constitutes the inverse-stopping type grout nipple.This example is established Φ 5 steel balls, Φ 4 inlet holes, Φ 8 outlet openings, and steel ball 2 diameters are greater than the aperture of inlet hole 4; Steel ball 2 diameters are less than the aperture of outlet opening 5.The utility model material source is wide, and cost is low, can design and produce according to the requirement and the commercially available steel ball size of grouting equipment gauge size.
Operating principle
Inverse-stopping type grout nipple two ends connect high-pressure rubber pipe 12 and grout pipe 13, see shown in Figure 3.When grouting slurries 9 pressurize in grouting cylinder 8 by forcing pipe 10, by high-pressure rubber pipe 12 with slurries 9 by the slip casting of in the distress in concrete 7 of concrete bodies 6, pressurizeing of this inverse-stopping type grout nipple, slurries are from without hindrance crack 7 (see figure 1)s that enter in space between steel ball 2 and mouth body 1 wall, when slurries are saturated in the crack, (there is instrument 11 to show), stop grouting, high-pressure rubber pipe 12 is extracted from the mouth mouth, this moment, mouth mouth place pressure was zero, but being the steel ball 2 that has the slurries of pressure condition moments to be about in the inverse-stopping type grout nipple in the crack pushes up to inlet hole 4 aperture (see figure 2)s, block the slurries ejection, and make slurries bonding more closely and solidify with the concrete of crack periphery or rock in the crack, reached the grouting purpose.
