Influence whether the bearing capacity of engineering pile and the normal use of structure.Common buildings filling pile construction, easily there are following several feelings
Condition：1st, during underwater gliders, conduit Transducers Embedded in Concrete depth deficiency；2nd, during tube drawing, conduit proposes concrete surface；3、
Concreting is discontinuous, pours overlong time；4th, borehole cleaning is not clean or do not carry out secondary pile hole cleaning；5th, conduit bottom is to bottom hole pitch
From excessive.These situations can all cause the concrete quality of bored concrete pile to decline, and have a strong impact on the bearing capacity of engineering pile.Also have at present
Such way：When colligation fills steel reinforcement cage, Grouting Pipe is reserved into colligation on steel reinforcement cage, after the completion for the treatment of concreting, needed
Stake detection is carried out, determines whether stake needs to carry out grouting treatment by examining report, makes up the mass defect of bored concrete pile.But this
The shortcomings that sample is done be：1st, the pulp hole site that Grouting Pipe leaves is fixed, and the position that can not judge grout outlet in advance is exactly concrete
The position of defect, reserved Grouting Pipe slurry outlet are not necessarily positioned to the position of mass defect；2nd, can not determine to work as during slip casting
The slip casting intensity of individual position, it is difficult to determine whether that slip casting should be stopped；3rd, slip casting intensity is difficult to control during slip casting, slip casting must not be determined
Amount；4th, slip casting process is to carry out slip casting to whole branch Grouting Pipe, it is difficult to determines the pressure of each slurry outlet, it is difficult to judge whether
Slip casting should be stopped, slip casting pressure skewness, slip casting effect is poor.
Utility model content
Deficiency, the technical problems to be solved in the utility model are to provide a kind of grouting device of bored concrete pile based on more than, protect
The grouting quality of each slip casting hole site is demonstrate,proved, pressure control quickly can be carried out to corresponding site, and controls injection rate, energy
Grouting pressure is enough improved, the quality and effect of slip casting is effectively ensured.
In order to solve the above technical problems, the utility model employs following technical scheme：
A kind of grouting device of bored concrete pile, including outer tube and inner tube, spacing is provided with slurry outlet on the outer tube, described
Position on outer tube positioned at slurry outlet is also arranged with rubber strip；Said inner tube is set in the outer tube, and said inner tube includes position
In being provided with injected hole in the first elastic portion of the nozzle position of said inner tube, said inner tube.
First elastic portion and the second elastic portion are made up of rubber.
The injected hole is arranged on the side wall of said inner tube.
The injected hole is oppositely arranged with the slurry outlet.
The bottom of said inner tube sets ferrule to seal.
Also include pipe shaft, first elastic portion, pipe shaft and the second elastic portion are sequentially communicated, the pipe shaft and described first
Elastic portion, the pipe shaft are connected with second elastic portion by metal joint.
The injected hole is arranged in the side wall or bottom wall of said inner tube.
Using above technical scheme, the utility model achieves following technique effect：
(1) grouting device of the utility model bored concrete pile can carry out slip casting to each injected hole in Grouting Pipe respectively,
Slip casting together is avoided to cause the slip casting pressure of each slip casting hole site to fully meet the pressure demand of the position, can be fine
Ground controls slip casting pressure, can effectively improve the quality of slip casting；And by setting the first elastic portion to strengthen the pressure of slurries
Power；
(2) slurry that the grouting device of the utility model bored concrete pile sprays in pulp hole site, can be pile body after curing
Strengthen frictional force, be advantageous to improve engineering pile bearing capacity.

Fig. 2 is Fig. 1 left view；
Fig. 3 is the structure chart of the inner tube of the grouting device of the utility model bored concrete pile.
Embodiment
As shown in Figure 1-Figure 3, the grouting device of bored concrete pile provided by the utility model includes outer tube 1 and inner tube 2, described outer
Spacing is provided with slurry outlet on pipe 1, and the position positioned at slurry outlet on the outer tube 1 is also arranged with rubber strip 11；Said inner tube 2
It is set in the outer tube 1, said inner tube 2 includes the first elastic portion 21 of the nozzle position positioned at said inner tube 2, said inner tube
Injected hole 25 is provided with 2.During slip casting, with the increase of the pressure of inner tube 2, the first elastic portion 21, which expands, blocks outer tube 1, outer tube
The space of opposing seal is formed in 1, with the further increase of slurry pressure in inner tube 2, slurries flow from the injected hole 25 of inner tube 2
Go out, and sprayed from slurry outlet.
Wherein, inner tube 2 also includes pipe shaft 23, and pipe shaft 23 connects with the first elastic portion 21, and in the present embodiment, inner tube 2 is also wrapped
The second elastic portion 22 is included, the first elastic portion 21, the elastic portion 22 of pipe shaft 23 and second are sequentially communicated, pipe shaft 23 and the described first elasticity
Portion 21, pipe shaft 23 are connected with second elastic portion 22 by metal joint 24.First elastic portion 21 and the second elastic portion 22
It is made up of rubber.The injected hole 25 is arranged on the side wall of said inner tube 2, and is located at the first elastic portion 21 and the second elastic portion 22
Between.The injected hole 25 is oppositely arranged with the slurry outlet.The bottom of said inner tube 2 sets ferrule to seal.When slip casting,
First elastic portion 21 and the second elastic portion 22 expand and block outer tube 1, and outer tube 1 is located at the first elastic portion 21 and the second elastic portion 22
Between space opposing seal, and whole inner tube 2 also opposing seal substantially increases grouting pressure, now the pressure of inner chamber
Constantly lifting, the rubber strip 11 on the slurry outlet of outer tube 1 is pressed off, cement mortar sprays from gap.In other specific embodiments,
Inner tube 2 can include the first elastic portion 21 and pipe shaft 23, and the first elastic portion 21 is connected with pipe shaft 23, and the first elastic portion 21 is located at
The nozzle position of inner tube 2, injected hole 25 are arranged on side wall or the bottom wall of inner tube 2.When injected hole 25 is arranged on the side wall of inner tube 2
When upper, injected hole 25 can also be oppositely arranged with slurry outlet.When slip casting, the first elastic portion 21, which expands, blocks outer tube 1, and first
Space opposing seal between elastic portion 21 and outer tube 1, and whole inner tube 2 also opposing seal, can also improve slip casting pressure
Power, now the pressure of inner chamber constantly lifted, the rubber strip 11 on the slurry outlet of outer tube 1 is pressed off, cement mortar sprays from gap.
The process of slip casting will pay close attention to the pressure value of inner chamber, treat that pressure value declines suddenly, then constant, last to rise to design pressure again
Power can stops slip casting, completes the mortar depositing construction of an injected hole 25.
Finally it should be noted that：Preferred embodiment of the present utility model is these are only, is not limited to this practicality
It is new, although the utility model is described in detail with reference to embodiment, for those skilled in the art, its according to
