Abstract
The utility model discloses a kind of Superfluid state concrete pile grouting device, and including the steel reinforcement cage being made of multiple groups collar tie beam and stringer, the stringer is fixed on collar tie beam, and Grouting Pipe is parallel with stringer and is fixed on collar tie beam；The lower section length of Grouting Pipe is more than lower end 200-300 millimeters of collar tie beam；Conus portion is arranged in the lower section of Grouting Pipe, and the maximum gauge of conus portion is greater than the outer diameter of Grouting Pipe；Multiple outfluxes are set to the tube wall of the Grouting Pipe between collar tie beam above conus portion；The support tube of oblique top is arranged in Grouting Pipe and lower part collar tie beam bearing, and the both ends of the support tube are fixed on collar tie beam.The utility model has the advantages that: since lower end is provided with Grouting Pipe, water is injected to the Soft Soil Layer of pile foundation bottom by Grouting Pipe and cement proportion is 1；The cement slurry of 1-2 solidifies pile foundation bottom, avoids sinking for pile foundation.
Description
Technical field
The utility model relates to building field, specifically a kind of grouting device.
Background technique
In construction, pile foundation generally uses long screw drill rod to tunnel to underground to projected depth back to lift drilling rod,
While drilling rod again hammers steel reinforcement cage in the pile foundation into shape after proposing by pouring channel poured concrete among drilling rod.Due to drilling rod
Bottom be an incomplete helical blade, therefore, the lowermost soil of pile foundation can not but have blade after being blended by blade
Output forms one 20-30 centimetres of Soft Soil Layer in the bottom of pile foundation, the axial bearing capacity of the presence of the Soft Soil Layer to pile foundation
It makes a big impact, pile foundation is be easy to cause to sink.
Utility model content
In order to solve the above-mentioned technical problem, the purpose of the utility model is to provide a kind of solution pile foundation the lowermost Soft Soil Layers
The sagging structure of caused pile foundation, specific technical solution are as follows:
A kind of Superfluid state concrete pile grouting device, it is described vertical including the steel reinforcement cage being made of multiple groups collar tie beam and stringer
Beam is fixed on collar tie beam, and Grouting Pipe is parallel with stringer and is fixed on collar tie beam；The lower section length of Grouting Pipe is more than the lower end of collar tie beam
200-300 millimeters；Conus portion is arranged in the lower section of Grouting Pipe, and the maximum gauge of conus portion is greater than the outer diameter of Grouting Pipe；On conus portion
Multiple outfluxes are arranged in the tube wall of side to the Grouting Pipe between collar tie beam；The branch of oblique top is arranged in Grouting Pipe and lower part collar tie beam bearing
The both ends of stay tube, the support tube are fixed on collar tie beam.
The Grouting Pipe is 2-6 root, and is distributed along collar tie beam even circumferential.
The cone angle of conus portion is 45-60 degree.
To save cost, Grouting Pipe replaces the stringer of position.
The utility model has the advantages that: since lower end is provided with Grouting Pipe, by Grouting Pipe to the Soft Soil Layer of pile foundation bottom
It injects water and cement proportion is 1；The cement slurry of 1-2 solidifies pile foundation bottom, avoids sinking for pile foundation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the top view of Fig. 1.
Specific embodiment
The utility model is illustrated with reference to the accompanying drawing, as shown, the utility model includes by multiple groups collar tie beam 1 and indulging
The steel reinforcement cage that beam 2 forms, the stringer 2 are fixed on collar tie beam 1, and Grouting Pipe 3 is parallel with stringer 2 and is fixed on collar tie beam 1；Slip casting
The lower section of pipe is more than that the length of collar tie beam part 4 is 200-300 millimeters；Conus portion 6 is arranged in the bottom of Grouting Pipe, and conus portion is most
Major diameter is greater than the outer diameter of Grouting Pipe, in this way, can be more than collar tie beam part 4 in the lower section of Grouting Pipe in Grouting Pipe folding process
Around formed a space 8, on the one hand the presence in the space 8 avoids blocking of the weak soil to Grouting Pipe tube wall outlet, another
Aspect, the space are convenient for the aggregation of cement slurry, form the cement stock tank an of entirety, preferably permeate around；
Multiple outfluxes 5 are arranged in the tube wall of conus portion 6 top to the Grouting Pipe between collar tie beam；
Biggish resistance is born other than the collar tie beam of lower part since the lower end of Grouting Pipe is prominent, which can be transferred to collar tie beam,
The deformation of collar tie beam is caused, to solve this problem, the support tube 7 of oblique top is arranged with lower part collar tie beam bearing for Grouting Pipe, described
The both ends of support tube 7 are fixed on collar tie beam by welding.
The Grouting Pipe is 2-6 root, and is distributed along collar tie beam even circumferential.
The cone angle of conus portion is 45-60 degree.
Grouting Pipe can also replace the stringer of position.
