Description
Technical field
The utility model relates to a kind of building operations shower nozzle, is specifically related to a kind of for the scalable slip casting shower nozzle in slip casting method construction technology.
Background technology
Slip casting method utilizes hydraulic pressure, air pressure or electrochemical principle; by Grouting Pipe, slurries are injected stratum uniformly; slurries are in modes such as filling, permeate and be compacted; its position is occupied after driving moisture between soil particle or in rock fracture and air away; after Artificial Control certain hour; originally loose grogs or crack are cemented to an entirety by slurries, form " a solid body " that structure is new, intensity is large, water resistance is good and chemical stability is good.
On-the-spot Normal practice uses voluntarily with the floral tube of steel pipe processing usually, injected hole adopts the mode that adhesive tape swathes or cushion rubber wraps up, adhesive tape can be caused after Grouting Pipe is driven underground, cushion rubber breakage causes injected hole to block or adhesive tape is wound around the blocked up phenomenon such as cannot to open, have impact on the effect of slip casting, the thing of doing over again is caused often to occur, greatly reduce effect of slip casting, workmanship and cost are affected all to some extent.
Utility model content

Fig. 2 for described in embodiment 2 for the structural representation of scalable shower nozzle of slip casting method construction.
In figure: the thick section of 1-pier, 2-links cap, 3-straight trough hole, 4-free segment, 5-cone, 6-circular hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.
Embodiment 1: as shown in Figure 1, a kind of scalable shower nozzle for slip casting method construction, comprise cone 5, shotcrete pipe and link cap 2, the described tail end of cone 5 is fixedly connected with the head end of shotcrete pipe, the tail end of described shotcrete pipe is the thick section 1 of pier, part between described shotcrete pipe head end and tail end is free segment 4, described link cap 2 is set on the free segment 4 of shotcrete pipe, the internal diameter of described link cap 2 equals the external diameter of shotcrete pipe free segment 4, can be free to slide between cone 5 and the thick section 1 of pier, described attachment cap 2 can be fixedly connected with the grout outlet of Grouting Pipe, the external diameter of the thick section 1 of described pier is less than the internal diameter of Grouting Pipe, the diameter of described cone 5 breech face is greater than the internal diameter of Grouting Pipe, described shotcrete pipe has some gunniting holes.
Described cone 5 is solid plummet, cone diameter 42mm, long 86mm, and the breech face center of cone 5 has internal thread screwed hole, and for connecting shotcrete pipe, cone can ensure that shotcrete pipe is delivered at the bottom of hole smoothly, and has guide effect.
The head end of described shotcrete pipe is the male end matched with internal thread screwed hole.
Described shotcrete pipe total length 245mm, middle free segment length is 190mm, and described gunniting hole is straight trough hole 3, the long 50mm in straight trough hole, wide 9mm, and described gunniting hole is quincuncial arrangement on shotcrete pipe sidewall.
Described attachment cap 2 is screwed connection cap; it is threaded with Grouting Pipe; screwed connection cap moves between cone 5 and the thick section two-end-point of pier; then gunniting hole is protected in slip casting steel pipe when moving to cone segments; in case gunniting hole is blocked; during pressurization whitewashing, first open injected hole by Grouting Pipe being pulled out 190mm, slurries spray from gunniting hole.
Concrete work progress is:
1, first scalable shower nozzle and Grouting Pipe are linked to be entirety, then shower nozzle cone point are aimed at surveying and locating point position, in shotcrete pipe indentation Grouting Pipe, the insertion angle of Grouting Pipe is according to its design and code requirement adjustment.
2, Grouting Pipe carries out piping length according to its slip casting degree of depth, and segmentation squeezes into Grouting Pipe to compacted soil layer depth.
3, after shower nozzle is squeezed into and reinforced soil layer desired depth, after Grouting Pipe is pulled out 190mm on the whole, top shower nozzle injected hole is opened, and Grouting Pipe upper end connects grouting equipment, carries out operation according to the grouting pressure of design and specification.
4, be in the milk in soil layer according to 20cm mono-layer method during slip casting, lower floor has noted and Grouting Pipe has been pulled out 20cm on the whole, and top shower nozzle moves 20cm, until whole soil layer has been reinforced move to next hole on also following.
Embodiment 2: as shown in Figure 2, the present embodiment provides a kind of scalable shower nozzle for slip casting method construction, and its structure is substantially identical with the scalable shower nozzle described in embodiment 1, and difference is: described gunniting hole is circular hole 6, and aperture is 9mm.
As mentioned above, although represented with reference to specific preferred embodiment and described the utility model, it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model not departing from claims definition, various change can be made in the form and details to it.
