Description
Technical field
The utility model is related to the casing dress of the foundation basic construction in construction project, more particularly to a kind of slip casting and pore-forming
Put.
Background technology
In the dealing with foundation construction of architectural engineering, casing is a kind of tool device being commonly used, and its effect is
Retaining wall is played in foundation soil body to act on and protect the pile body of its inside in work progress, but the effect of casing at present
Also it is only limitted to this.
Slip casting method is a kind of general construction that will be injected into using compression pump with the slurries for reinforcing property in foundation soil body
Technology, the purpose is to make the slurries of injection permeate and spread in the soil body, reached after certain time solidifies strengthening stratum and
The purposes such as impervious waterproof, its reinforcing to underground structure, the effect of waterproof are obvious.But current slip casting method is usually
After pile body construction completely, then the consolidation process individually carried out, the quality and slip casting efficiency of slip casting can not ensure.
The content of the invention
The application is directed to issue noted above, the shortcoming of prior art is overcome, by slip casting method and the ingenious knot of casing function
There is provided a kind of casing device that slip casting and pore-forming dual-use function are realized in foundation basic construction after conjunction, it is characterised in that described
The outer wall of the stack shell of casing device is fixed with the Grouting Pipe of more than two, the bottom of Grouting Pipe or and bottom surrounded provided with multiple
The vertical nozzle Huo of stack shell and horizontal nozzle, the casing device, to when being lowered into and proposing upwards, can in foundation soil body
Impacted to Grouting Pipe inner high voltage slip casting formation impact jet flow and lubricate the soil body, realize the dual raising of efficiency of construction and quality.
In above-mentioned casing device, the bottom of Grouting Pipe or and bottom be set to annular tube shaped around stack shell, it is above-mentioned vertical
Nozzle Huo and horizontal nozzle are on ring pipe.
In above-mentioned casing device, vertical nozzle Huo and horizontal nozzle are connected from different Grouting Pipes respectively, and slip casting
The upper end of pipe is respectively equipped with controlling switch, and vertical nozzle Huo and horizontal nozzle can be controlled individually to spray or while spray.
In the foundation basic construction of the casing device, injecting treatment can be carried out in pore forming process, i.e. the casing device
To when being lowered into foundation soil body, if running into the relatively hard stratum of the unfavorable pore-forming of such as layer of sand, it can be sprayed using slip casting
Method make cement grout spray the soil body, serve the double action of the impact grinding soil body and lubrication cooling, make pore forming process efficiently,
Rapidly；Likewise, after the pile body construction in casing device is finished, when proposing the casing device upwards in foundation soil body,
Also the method that can be sprayed using slip casting makes cement grout spray the soil body, fills up cement grout empty between pile body and the side wall soil body
Gap, and the foundation soil body around pile body is reinforced, serve the dual work for improving efficiency of construction and increase lateral frictional force
With；Meanwhile, the casing device, by vertical nozzle and horizontal nozzle, can carry out twocouese during slip casting to surrounding soil
Injection, so as to be obviously improved jeting effect, and by the regulation to controlling switch in Grouting Pipe, can select to carry out list at any time
Only vertical injection or transverse injection, or sprayed while twocouese, form of construction work is flexible and changeable.
Brief description of the drawings
Fig. 1 is the structural representation of a preferred embodiment of casing device of the present utility model；Fig. 2 is the embodiment
The structural representation of bottom amplification.
Embodiment
As depicted in figs. 1 and 2, the stack shell 1 of casing device is leptosomatic circular steel cylinder, the outer wall both sides of stack shell 1 along its
Length direction is fixed with Grouting Pipe 2 and Grouting Pipe 3, and the bottom of Grouting Pipe 2 is to be pressed on the ring pipe 4 around stack shell 1, ring pipe 4
Identical spacing is provided with four horizontal nozzles 5, and the spray angle of horizontal nozzle 5 is horizontal direction, and the bottom of Grouting Pipe 3 is around cylinder
By identical spacing provided with four vertical nozzles 7 on the ring pipe 6 of body 1, ring pipe 6, the spray angle of vertical nozzle 7 is Vertical Square
To the upper end of Grouting Pipe 2 and Grouting Pipe 3 is equipped with controlling switch 8, and Grouting Pipe 2 and Grouting Pipe can be controlled by controlling switch 8
3 slip casting quantity or pressure value, that is to say that control nozzle 5 and nozzle 7 individually spray or while sprayed.
