Two springs 53, the fixed block 52 is through inside the second spring 53；In order to by the first steel pipe pile body 13
After inside injection cement slurry, it is flowed by cement slurry self gravity from the slurry-feeding hole 44 of the 41 top side wall of fixing sleeve
Behind 51 inside of fixing pipe, after cement slurry inside the fixing pipe 51 is cumulative, start to push two fixed blocks
52, it shrinks the second spring 53 and generates elastic force, two fixed blocks 52 are pushed into the first steel-pipe pile sheet respectively
Inside the limiting slot 15 inside body 13 and the second steel pipe pile body 31, the fixed block 52 is made to start to squeeze the limit
Two elastic pieces 14 inside the slot 15 of position make two elastic pieces 14 generate elastic force, enter in the fixed block 52
Behind 15 inside of limiting slot, is squeezed by the clamping of two elastic pieces 14 and the elastic force of the second spring 53, make institute
It states fixed block 52 to be well fixed on inside the limiting slot 15, to make the first steel pipe pile body 13 and second steel
Tubular pole ontology 31 can be more stably fixed on the connector 2, and the cement slurry inside the fixing pipe 51 is gradually solid
After change, the expansion force after cement solidification is slowed down by the elastic force of the second spring 53, the cement after solidification continues to squeeze
The fixed block 52 is pushed, makes the fixed block 52 without departing from the limiting slot 15, the connector 2 is enable preferably to consolidate
The fixed first steel pipe pile body 13 and the second steel pipe pile body 31.
Specifically, the support construction 4 includes fixing sleeve 41, supporting block 42, the first spring 43 and slurry-feeding hole 44, two institutes
The fixing sleeve 41 that fixing pipe 51 is respectively and fixedly provided with inner hollow is stated, two fixing sleeves 41 are respectively communicated with two fixations
Pipe 51, two fixing sleeves 41 are respectively positioned on inside the connector 2, and two fixing sleeves 41 slidably connect T-shaped
The supporting block 42 of structure, the supporting block 42 are located at outside the fixing sleeve 41 for arcuate structure, two supporting blocks
Minimum range between 42 is less than the distance between two described fixing sleeves 41, between the supporting block 42 and the fixing sleeve 41
It is fixed with first spring 43, through inside first spring 43, two fixing sleeves 41 push up the supporting block 42
End side wall offers the slurry-feeding hole 44, and two slurry-feeding holes 44 are respectively communicated with two fixing pipes 51, described into slurry
Internal diameter of the hole 44 from top to bottom end is gradually reduced；In order to which cement slurry is injected into the first steel pipe pile body 13 interrupted
Behind inside, cement slurry is entered inside the fixing pipe 51 during falling from the slurry-feeding hole 44, while cement slurry falls
During hit two 42 sides of supporting block arcuate structure, the supporting block 42 is pushed into the fixing sleeve 41
Behind portion, shrinks first spring 43 and generate elastic force, while the mistake that the supporting block 42 is slided to 51 direction of fixing pipe
It will further be pushed inside the fixing pipe 51 from the cement slurry that the slurry-feeding hole 44 is fallen into journey, in the first steel-pipe pile sheet
When the cement slurry injected in body 13 is reduced, the cement slurry for dropping into 42 arcuate structure of supporting block is reduced through first bullet
The elastic force of spring 43 makes the supporting block 42 set back, and a large amount of cement slurries are injected into the first steel pipe pile body 13 again
Afterwards, a part of cement slurry is flowed into inside the fixing pipe 51 from the slurry-feeding hole 44, and another part cement slurry, which falls, pushes institute
It states supporting block 42 and is flowed into 31 bottom end of the second steel pipe pile body, slide the supporting block 42 back and forth on the fixing sleeve 41
It is dynamic to be pushed into inside the fixing pipe 51 from the cement slurry that the slurry-feeding hole is fallen into, make the cement slurry inside the fixing pipe 51
It measures more and more, increases the intensity inside the fixing pipe 51.
When in use, it is inserted into and beats after first connecting the first steel pipe pile body by connector with the second steel pipe pile body
Inside stake holes after good, by discontinuously injecting cement slurry to the first steel-pipe pile body interior, inject cement slurry step by step
To the first steel pipe pile body and the second steel-pipe pile body interior, cement slurry enters solid from slurry-feeding hole 44 during falling
Determine inside pipe 51, while hitting the arcuate structure of two 42 sides of supporting block during cement slurry falls, supporting block 42 is pushed away
Enter to after 41 inside of fixing sleeve, shrinks the first spring 43 and generate elastic force, while supporting block 42 is slided to 51 direction of fixing pipe
It will further push inside fixing pipe 51 from the cement slurry that slurry-feeding hole 44 is fallen into, injected in the first steel pipe pile body 13 in the process
Cement slurry when reducing, the cement slurry for dropping into 42 arcuate structure of supporting block, which is reduced, by the elastic force of the first spring 43 makes supporting block
42 set back, and after a large amount of cement slurries are injected into the first steel pipe pile body 13 again, a part of cement slurry is from slurry-feeding hole 44
It being flowed into inside fixing pipe 51, another part cement slurry, which falls, pushes supporting block 42 to be flowed into 31 bottom end of the second steel pipe pile body,
Make supporting block 42 reciprocatingly slide on fixing sleeve 41 cement slurry fallen into from slurry-feeding hole is pushed into inside fixing pipe 51, makes to fix
Cement slurry volume inside pipe 51 is more and more, increases the intensity inside fixing pipe 51, the cement slurry inside fixing pipe 51 it is more long-pending more
After mostly, start to push two fixed blocks 52, shrink second spring 53 and generate elastic force, two fixed blocks 52 are pushed into the respectively
Inside limiting slot 15 inside one steel pipe pile body 13 and the second steel pipe pile body 31, fixed block 52 is made to start to squeeze limiting slot 15
Two internal elastic pieces 14 make two elastic pieces 14 generate elastic force and pass through after fixed block 52 enters 15 inside of limiting slot
The clamping of two elastic pieces 14 and the elastic force of second spring 53 squeeze, and are well fixed on fixed block 52 inside limiting slot 15,
To enable the first steel pipe pile body 13 and the second steel pipe pile body 31 to be more stably fixed on connector 2, in fixation
After cement slurry inside pipe 51 gradually solidifies, slow down the expansion force after cement solidification by the elastic force of second spring 53, Gu
Cement after change, which continues to squeeze, pushes fixed block 52, makes fixed block 52 without departing from limiting slot 15, keeps connector 2 better
Fix the first steel pipe pile body 13 and the second steel pipe pile body 31, after being filled up inside fixing pipe 51 by cement slurry, fixing pipe 51
Internal cement slurry starts to push two supporting blocks 42, and making two supporting blocks 42, sliding mutually contradicts in the same direction, to make connector 2
Inside is supported after the cement solidification inside two fixing pipes 51 with two supporting blocks 42, is further increased inside connector 2
Intensity avoids connector 2 from being squeezed and damaged by the soil and rock around stake holes, finally continues to inside the first steel pipe pile body 13
Cement slurry is injected, after the first steel pipe pile body 13 and the solid cement slurry of the second steel pipe pile body 31, completes steel-pipe pile
It is inserted into stake holes.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the description in above embodiment and specification only illustrates the present invention
Principle, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these variation and
Improvement is both fallen in the scope of protection of present invention.The claimed scope of the invention is by appended claims and its equivalent
Object defines.
