Detailed Description
As shown in fig. 1, a grouting gun for emergency plugging is used for plugging when an envelope of an underground engineering leaks; the liquid injection gun comprises a gun barrel 11, a gun head 12 and a piston 13 in the gun barrel 11, wherein a liquid bag 2 is arranged in a cavity between the piston 13 and the gun head 12 in the gun barrel 11;
the gun barrel 11 is filled with epoxy AB glue, and the liquid A and the liquid B of the epoxy AB glue are separated by the wall of the liquid bag 2. In this embodiment, the liquid B of the epoxy AB glue is disposed in the liquid bag 2, and the liquid a is disposed in the cavity between the liquid bag 2 and the gun barrel 11. The liquid A of epoxy AB glue is comparatively thick, is the resin of cream usually, and liquid B is the curing agent that viscosity is slightly low, if set up the liquid A of cream in liquid bag 2, can appear in the in-service use that liquid bag 2 breaks and plug up whole barrel 11, leads to the problem that can't extrude the liquid in barrel 11 smoothly, consequently need set up liquid A in the position that is close to barrel 11, and liquid B sets up in liquid bag 2. In addition, for the rapid curing of epoxy AB adhesives, fatty amine-based curing agents are preferably used here.
The tail of the gun head 12 is wrapped with an expansion water stop strip 121 for preventing the injected epoxy AB glue from overflowing, and the expansion water stop strip 121 is plugged at the split after the gun head 12 is inserted, so that the epoxy AB glue is prevented from overflowing. The lance tip 12 in this embodiment is a flat lance tip 12.
As shown in fig. 2, the liquid injection gun is a pneumatic liquid injection gun, and further comprises a compressed gas cylinder 14 and a valve 15; the end of the gun barrel 11 far away from the gun head 12 is closed, the end of the compressed gas cylinder 14 far away from the gun head 12 penetrates through the gun barrel 11 and is communicated with the inner space of the gun barrel 11, and the valve 15 is arranged on the outlet pipe of the compressed gas cylinder 14. For plugging work. The compressed air cylinder 14 should store compressed air with a pressure of 2-3 mpa to allow the epoxy AB glue to be extruded out quickly to the place where the leakage occurs. Of course, the liquid injection gun can also be a conventional manual liquid injection gun, but the injection is slow and the epoxy AB glue is difficult to be injected into the deep part of the leakage point.
The liquid bag 2 is cylindrical and is coaxially arranged with the gun barrel 11, one end of the liquid bag 2 is arranged by being attached to the piston 13, the other end of the liquid bag is anchored on the inner wall of the gun barrel 11, and a gap is reserved between the anchoring position and the gun head 12. The purpose of the gap here is to avoid that the ruptured sac 2 blocks the lance tip 12.
As shown in fig. 1, 3 and 4, a fixed orifice plate 3 with a plate surface perpendicular to the axis of the gun barrel 11 is anchored in a cavity between the piston 13 and the gun head 12 in the gun barrel 11, and one end of the liquid bag 2 close to the gun head 12 is inserted on the fixed orifice plate 3 and is fixedly connected with the fixed orifice plate 3. The function of the fixed orifice plate 3 is to mix the liquid A and the liquid B after passing through the holes on the fixed orifice plate 3 after the liquid capsule 2 is broken.
In the present embodiment, as shown in fig. 4, the fixed orifice plate 3 is a grid plate, and the liquid sac 2 is inserted into a grid on the fixed orifice plate 3, so that the fixation is convenient.
The utility model relates to a slip casting rifle for emergent leaking stoppage, its use includes following step:
the method comprises the following steps: taking a piece of the utility model, inserting the gun head 12 at the position where leakage occurs and enabling the expansion water stop strip 121 at the tail part of the gun head 12 to block the leakage point; if the location of the leak is difficult to reach or insert the lance tip 12, the lance tip 12 may also be inserted by drilling around the location of the leak;
step two: the valve 15 is opened and epoxy AB glue is injected.
