Specific embodiment
The embodiment of the present invention is described in further detail below in conjunction with attached drawing.
Referring to shown in Fig. 1-Fig. 2, the embodiment of the present invention provides the dredger and dredging method of a kind of filling concrete pipe,
Including mounting base 1, mounting base 1 includes main body 10 and the pipe joint component being installed in main body 10, and pipe joint component is used
It is connected in the sealing of filling concrete pipe 4, pipe joint component one end is installed in main body 10, the other end and filling concrete pipe
4 sealings are connected.From the angle of structure design and air-tightness, since filling concrete pipe 4 is circular section, lead
The preferably cylindrical structure of tube joint assembly, and in order to guarantee to be connected to, pipe joint component is hollow cylindrical structure.Due to
It in the prior art, may be the pipe of various different size bores for the intrusion pipe of concrete perfusion 4, in order to guarantee dredging dress
The universal and practicability of itself is set, pipe joint component includes the pipe joint 11 of multiple and different nozzle diameters, multiple conduits
Connector 11 can select one and removably be connected with the sealing of filling concrete pipe 4, when using dredger, according to construction site
The practical caliber of filling concrete pipe 4 selects matching pipe joint 11.Wherein pipe joint 11 and main body 10 and coagulation
Native intrusion pipe 4 can connect by any suitable means, due to when intrusion pipe 4 concrete blocking after, such as not in time quickly
It dredges, the concrete in pipe is easy to solidify, and the difficulty of dredging can be greatly increased after solidifying, therefore Fast Installation for convenience
With disassembly pipe joint 11, it is connected through a screw thread between pipe joint 11 and main body 10 and filling concrete pipe 4, facilitates installation
Air-tightness is good while disassembly.In order to further ensure the gas of pipe joint 11 and 4 junction of main body 10 and filling concrete pipe
Close property is equipped with seal rubber cushion on the both ends end of pipe joint 11, can guarantee the leakproofness of junction well, keep away
Exempt from because air pressure inside is excessive and there is a situation where gas leakage, influence the performance of device.
Referring to shown in Fig. 1-Fig. 2, further including supercharging device 2, supercharging device 2 include the air inlet pipe 20 in main body 10 with
And the air compressor 21 being connected with air inlet pipe 20, the angle designed from structure, in order to guarantee the air-tightness of device, air inlet
Pipe 20 and main body 10 are integrally formed, and air inlet pipe 20 is connected with air compressor 21 by hose 22, in order to guarantee air inlet pipe 20 and
The air-tightness of 22 junction of high-pressure hose, hose 22 are preferably high-pressure hose 22, while being connected in air inlet pipe 20 and high-pressure hose 22
It meets place and is equipped with clip, can guarantee and form one between air compressor 21, hose 22, air inlet pipe 20, mounting base 1 and intrusion pipe 4
A closed inlet channel that is isolated from the outside world.Then the compressed air in a short time of air compressor 21 passes through high-pressure hose 22
By compressed air via entering the filling concrete pipe that is blocked by concrete after air inlet pipe 20, main body 10 and pipe joint 11
In 4, due to completely cutting off completely with extraneous, the pressure in filling concrete pipe 4 is gradually risen, when pressure rise to a certain fixed value
When, the concrete of plugging is gradually pushed out to outside nozzle under high pressure and air-flow with certain flow rate, completes coagulation in tube body
The dredging of native intrusion pipe 4.
It further include safety valve 3, safety valve 3 is set to guarantee the safety problem during dredging referring to shown in Fig. 1-Fig. 2
In in main body 10, safety valve 3 is mainly used for the pressure release of filling concrete pipe 4, prevents during dredging since hypertonia is made
At accident.During dredging, when the pressure value in filling concrete pipe 4 is more than the setting value of safety valve 3, safety valve 3 is certainly
It is dynamic to open, to reduce the pressure in filling concrete pipe 4.Further, it is additionally provided with exhaust valve 12 in main body 10, when dredging work
After the completion, before dismantling dredger, it is consistent with atmospheric pressure by 4 pressure release of filling concrete pipe to first pass through exhaust valve 12, guarantees peace
Quan Xing.Further, it is additionally provided with pressure gauge 13 in main body 10, facilitates the pressure value inside real-time monitoring filling concrete pipe 4, just
It is adjusted in real time according to the actual situation in operator, it is convenient and practical.
The embodiment of the invention also provides the dredging methods of filling concrete pipe 4, using above-mentioned dredger to coagulation
Native intrusion pipe 4 is dredged, and dredging method includes: the nozzle diameter of intrusion pipe 4 determining first, and selection matches with nozzle diameter
Pipe joint 11, first one end of pipe joint 11 is connected with main body 10 by the way of threaded connection, similarly use screw thread
Another section of pipe joint 11 connect by the mode of connection with intrusion pipe 4 again；It then will be with main body 10 1 by high-pressure hose 22
Body formed air inlet pipe 20 is connected with air compressor 21, soft in air inlet pipe 20 and high pressure in order to ensure the leakproofness of junction
The junction setting one of pipe 22 is for fastening the clip of tightening.After the completion of connection, intrusion pipe 4, mounting base 1, supercharging device 2 it
Between form the venting channels for being isolated from the outside world sealing, the secure threshold of safety valve 3 is set, open air compressor 21 start it is past
Compressed gas is inputted in intrusion pipe 4, with the input of gas, pressure is constantly increased in intrusion pipe 4, the pressure generated using gas
The concrete being blocked in intrusion pipe 4 is pushed out to nozzle with the flow velocity of gas itself.During dredging, if in intrusion pipe 4
Pressure is more than the threshold value of safety valve 3, then open the safety-valve 3 pressure releases, and the appropriate pressure value reduced in intrusion pipe 4, guarantee was dredged
Safety in journey；Before dredging terminates to remove device, exhaust valve 12 is first opened, using exhaust valve 12 first by the pressure in intrusion pipe 4
Force value drops to consistent with atmospheric pressure, and the atmospheric pressure value in the real-time sighting tube of pressure gauge 13 is utilized when pressure release, will when atmospheric pressure value is 0
Pipe joint 11 is removed from intrusion pipe 4, and dredger and intrusion pipe 4 are separated, and completes the dredging of intrusion pipe 4.
The present invention is not only limited to above-mentioned preferred forms, anyone can show that other are each under the inspiration of the present invention
The product of kind form, however, make any variation in its shape or structure, it is all with identical or similar with the present invention
Technical solution, within its protection scope.
