Description
Technical field
The utility model relates to the secondary punching technical fields in bored pile construction, and in particular to a kind of dichotomous brill
The efficient punching conduit of hole pouring pile.
Background technique
Cast-in-situ bored pile is common pile foundation form in modern construction, in its formation of pile, secondary pile hole cleaning effect
It is most important for pile quality.Bottom hole sediment can seriously affect the bearing capacity of cast-in-situ bored pile, need to be by way of borehole cleaning
It removes.
Currently, mostly using traditional straight barrel type conduit to carry out secondary punching, this kind of mode during bored pile construction
So that mud is rushed at bottom hole straight down, is back to aperture then up.Its mud flow is straight up and down, it is easy to form laminar flow
Phenomenon causes the sediment of other positions in hole that cannot all remove.
Summary of the invention
To overcome the deficiency, the purpose of this utility model is to provide a kind of dichotomous efficient punchings of cast-in-situ bored pile to lead
Pipe, the bootable mud flow of the device make inner hole deposition slag obtain comprehensive removing.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of dichotomous cast-in-situ bored pile efficiently rushes
Hole conduit, including main pipe, bifurcated catheter, the leading bottom of the tube are connected with bifurcated catheter, the inside of main pipe and bifurcated
The inside of conduit is connected, and the bifurcated catheter includes a bifurcated straight catheter, two bifurcated bending conduits.
Specifically, the main pipe is vertically connect with bifurcated straight catheter, and main pipe and bifurcated straight catheter are in same straight line
On, two bifurcated bending conduits are located at the two sides of bifurcated straight catheter, one end of two bifurcated swan-necks and bifurcated straight catheter
It is connected, the other end of bifurcated swan-neck is in horizontality, and the direction being open is opposite.
Specifically, the bifurcated bending conduit is set as a quarter annular shape.
The utility model has the following beneficial effects: the efficient punching conduit of the dichotomous cast-in-situ bored pile of (1) the utility model,
Original working procedure is varied without, only need to replace original bottom conduit with the device, it is easy to operate, it is easy for construction；(2) originally
The bootable mud flow of utility model, rises it in the shape of a spiral, and inner hole deposition slag is made to obtain comprehensive removing, punching effect is good,
It is high-efficient；(3) utility model device principle simplicity, low manufacture cost, installation procedure are simple and convenient to operate, and are greatly improved
Secondary punching efficiency in bored pile construction.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
1 stake holes in figure, 2 main pipes, 3 bifurcated bending conduits, 4 bifurcated straight catheters, 5 sediments, 6 mud flows.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.
A kind of dichotomous efficient punching conduit of cast-in-situ bored pile as shown in Figure 1, including main pipe 2, bifurcated catheter, it is described
2 bottom of main pipe is connected with bifurcated catheter, and the inside of main pipe 2 and the inside of bifurcated catheter are connected, the bifurcated catheter
Including 4, two bifurcated bending conduits 3 of a bifurcated straight catheter.
Specifically, the main pipe 2 is vertically connect with bifurcated straight catheter 4, and main pipe 2 and bifurcated straight catheter 4 are in same
On straight line, two bifurcated bending conduits 3 are located at the two sides of bifurcated straight catheter 4, one end of two bifurcated swan-necks 3 and bifurcated
Straight catheter 4 is connected, and the other end of bifurcated swan-neck 3 is in horizontality, and the direction being open is opposite.
Specifically, the bifurcated bending conduit 3 is set as a quarter annular shape.
The efficient punching conduit of the dichotomous cast-in-situ bored pile of the utility model, working method are as follows: decentralization is completed in the construction of stake holes 1
After steel reinforcement cage, merogenesis transfers conduit, and bifurcated catheter is located at lowermost end, bifurcated catheter is transferred to 1 bottom of stake holes, bifurcated is directly led at this time
Pipe 4 is blocked by 1 bottom of stake holes；It opens slush pump and starts punching, mud enters bifurcated bending conduit 3 by main pipe 2, is dividing
Under the water conservancy diversion for pitching bending conduit 3, mud rises in the shape of a spiral in hole, by the punching of sediment 5 at each position in stake holes 1 to aperture；Punching
Conduit is rotated clockwise 90 degree every 2-5 minutes during hole, guarantees that the sediment 5 of 1 bottom all directions of stake holes is rushed；
After the completion of punching, closes slush pump and carry out subsequent processing construction.
The utility model is not limited to the embodiment, anyone, which should learn, makes under the enlightenment of the utility model
Structure change, it is all that there is same or similar technical solution with the utility model, each fall within the protection scope of the utility model
Within.
Technology that the utility model is not described in detail, shape, construction portion are well-known technique.
