A slip head assembly according to some embodiments of the present application is described below with reference to fig. 1-4.
Referring to fig. 1 to 3, an embodiment of the present application provides a grouting head assembly including: a grouting head body 1 and an elastic expansion member 2; wherein, the elastic expansion component 2 is arranged outside the grouting head body 1;
the elastic expansion member 2 has a hollow structure inside, and the hollow volume inside is variable;
the elastic expansion member 2 is formed with an inlet end to which a pressurizing device 5 (being a pressure source) can be connected.
When in use, the grouting head body 1 is connected with a grouting pipe, the inlet end of the elastic expansion member 2 is connected with a pressurizing device 5 through a pipe fitting (for example, the pressurizing device 5 can be a hydraulic device, and the pressurizing device 5 will be exemplified as a hydraulic device later, but the pressurizing device 5 is not limited to a hydraulic device, the pressurizing device 5 can also be an air charging and discharging device, gas is charged into the elastic expansion member 2, and it is noted that the pressurizing device 5 can be a component contained in the grouting head assembly and can not belong to the grouting head assembly), the grouting head body 1 is placed into a drill hole, after hydraulic oil is charged into the elastic expansion member 2, the elastic expansion member 2 is expanded to block the drill hole, the pressure in the elastic expansion member 2 is recorded by a pressure gauge of the hydraulic device, the larger the pressure is, the closer the elastic expansion member 2 is contacted with the drill hole is, the better blocking effect is obtained, the slurry is not easy to leak, and the grouting head body 1 is not easy to shake, so that the grouting pressure is stable.
After grouting is completed, hydraulic oil can be extracted from the elastic expansion member 2 through hydraulic equipment, the elastic expansion member 2 contracts, and the grouting head body 1 can be conveniently taken out from a drilled hole.
It can be seen that, owing to add elastic expansion component 2 in the outside of slip casting head body 1, its inside can fill dress hydraulic oil etc. makes its inflation, and then plugs up the drilling, plays the effect that prevents to leak the thick liquid, makes slip casting head body 1 be difficult for rocking moreover, guarantees that slip casting pressure is stable.
In this embodiment, preferably, as shown in fig. 1 and 2, the elastic expansion member 2 is an elastic pipe, and the elastic pipe is wound around the outside of the grouting head body 1, one end of the elastic pipe is formed as an inlet end, and the opposite other end of the elastic expansion member 2 is formed as a closed end.
According to the structure described above, the elastic pipe is wound outside the grouting head body 1, and expands uniformly in the circumferential direction of the grouting head body 1, so that the plugging effect is improved.
Of course, not limited to this, as shown in fig. 3, the elastic expansion member 2 may also have a ring structure, and it is sleeved outside the grouting head body 1 and still able to expand to block the drilled hole.
In this embodiment, preferably, the elastic expansion member 2 is adhered to the outside of the grouting head body 1, so that the elastic expansion member 2 forms a stable connection with the grouting head body 1.
Certainly, not only be limited to sticky fixed, still can adopt following mode fixed elastic expansion component 2, the slip casting head subassembly still includes solid fixed ring, and solid fixed ring cover is located the outside of slip casting head body 1, and elastic expansion component 2's part is pressed and is located between solid fixed ring and the slip casting head body 1.
In this embodiment, preferably, as shown in fig. 1 to 3, the grouting head body 1 includes a support pipe 11, a grouting pipe 12, and a grouting head 13 connected to the grouting pipe 12;
the grouting pipe fitting 12 is arranged inside the supporting pipe fitting 11, the grouting pipe fitting 12 is rotatably connected with the supporting pipe fitting 11, and the grouting head 13 can extend out of the supporting pipe fitting 11; the elastic expansion member 2 is provided outside the support tube 11.
According to the above-described structure, the grouting pipe member 12 is used to connect a grout inlet pipe for supplying grout to the grouting head 13, the grouting head 13 performs grouting operation, and the support pipe member 11 serves to support the grouting pipe member 12.
Wherein, preferably, as shown in fig. 1 to 3, the grouting pipe fitting 12 is in threaded connection with the supporting pipe fitting 11, so as to facilitate later disassembly, maintenance or replacement.
In this embodiment, preferably, as shown in fig. 1 to 4, the grouting head assembly further includes an elastic ring 3 and a support bar 4; wherein, the elastic ring 3 is sleeved outside the supporting pipe 11 and connected with the supporting pipe 11;
one end of the support rod member 4 is fixedly connected to the grouting head 13, and the other opposite end of the support rod member 4 is inserted into an installation space formed by the elastic ring 3 and the outer wall surface of the support rod member 4.
As can be seen from the above-described structure, in using the present grouting head assembly, the grouting pipe member 12 is connected to the grout inlet pipe, the inlet end of the elastic expansion member 2 is connected to the pressurizing device 5 through the pipe member, the support pipe member 11 is put into the borehole, after the hydraulic oil is injected into the elastic expansion member 2, the elastic expansion member 2 is expanded to block the drilled hole, then the grouting pipe 12 is lifted in a rotating way, the grouting pipe 12 drives the grouting head 13 and the support rod 4 to move upwards, the end part of the support pipe 11 close to the grouting head 13 interferes with the support rod 4, the support rod 4 is forced to be opened by taking the grouting head 13 as the center until the end part of the support rod 4 far away from the grouting head 13 is abutted against the lower surface of the cement concrete slab 6, so that the grouting head body 1 is further fixed, and then avoid the slip casting in-process to appear rocking to guarantee slip casting pressure stability, improve slip casting efficiency. Of course, not limited to the above-described operating steps, it is also possible to open the support rods 4 first, making them abut against the lower surface of the cement concrete slab 6, and then to press the elastic expansion members 2, making them expand and block the drilled holes.
After grouting is finished, the grouting pipe fitting 12 can be moved downwards, the grouting pipe fitting 12 drives the grouting head 13 to move downwards together with the support rod piece 4, the support rod piece 4 is gradually close to the support pipe fitting 11 to be stored under the compression action of the elastic ring, the end part, far away from the grouting head 13, of the support rod piece 4 is also separated from the lower surface of the cement concrete slab 6, then or simultaneously, the pressure of the elastic expansion member 2 is released, so that the elastic expansion member 2 contracts, the grouting hole is not blocked by the elastic expansion member 2, and finally, the grouting head assembly can be completely taken out from the grouting hole smoothly.
It can be seen that the structural design of the support rod 4 and the elastic ring 3 plays a role in reinforcing the grouting head body 1 and a role in double insurance on the basis of the elastic expansion member 2.
Wherein, optionally, the support rod 4 can be a stainless steel metal rod with high strength and corrosion resistance.
Here, preferably, as shown in fig. 4, the number of the support bars 4 is plural, and the plural support bars 4 are arranged at regular intervals around the circumference of the grouting head 13.
According to the structure described above, the structural arrangement enables the grouting head body 1 to be fixed more stably.
Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
