Specific embodiment
Load box structure of the present invention is further described in conjunction with Fig. 1 to Fig. 5.
It is a kind of improve pile foundation autobalanced detection after strength of pile body load box structure, including loading unit assembly 1, weldering
The bottom offset for connecing the upper displacement bar assembly 2 for being fixed on 1 top of loading unit assembly and being fixedly welded on 1 lower part of loading unit assembly
Bar assembly 3, it is characterized in that: further including having retractable rod 4 and slip casting component.
The loading unit assembly 1 includes loading unit 11, upper inner ring 13, lower inner ring 14 and upper outer ring 12.
There are five the tools of loading unit 11 and circumferentially evenly distributed setting, and loading unit 11 is the prior art, because
This its specific structure the present embodiment is not described in detail.
The upper inner ring 13 and lower inner ring 14 are between multiple loading units 11, and the setting that is arranged above and below, and on
Inner ring 13 is connect by upper junction plate 15 with the upper part of each loading unit 11, i.e. the upper part of loading unit, upper junction plate
Be welding between upper inner ring 13, lower inner ring 14 is connect by lower connecting plate 16 with the lower part of each loading unit 11, i.e., plus
It is welding between the lower part of carrier unit, lower connecting plate and lower inner ring 14；The upper and bottom section of loading unit 11 is to open
Subject to face, i.e., upper and bottom section refers to down each other, and moving relatively upward is upper part, relative under moving down and being
Part；
The upper outer ring 12 is located at the periphery of multiple loading units and welds simultaneously with the upper part of multiple loading units 11
It is fixed；
The slip casting component includes annular slip casting channel 5 and grouting pipe；The annular slip casting channel 5 is located at multiple loads
The periphery of unit is simultaneously welded and fixed with the lower part of multiple loading units 11 simultaneously；
The retractable rod 4 have it is multiple, each retractable rod 4 include interior bar 41 and outer tube 42, it is described in
The portion of bar 41 is located in outer tube 42, and interior bar 41 is located at the outer wall of 42 part of outer tube and the inner wall of outer tube 42
Between form serous cavity 43, there is on the outer tube 42 pulp inlet；Multiple retractable rods 4 connect with annular slip casting channel 5
It connects, and the loading direction of the telescopic direction of retractable rod 4 and loading unit assembly 1 is arranged in parallel and each outer tube
42 pulp inlet is respectively positioned in annular slip casting channel 5；One end of the grouting pipe is connect with annular slip casting channel 5, the other end
For stock inlet, to each 43 slip casting of serous cavity.
When engineering pile in-site installation, the upper steel reinforcement cage of interior bar 41 and engineering pile is welded and taken up with steel wire, outer tube 42
It welds with descending reinforcing cage and is taken up with steel wire；When self-balancing approach detects, by preset load pipeline toward each loading unit 11
Slip casting, so that the upper and bottom section of each loading unit relatively moves, to drive upper descending reinforcing cage to move up and down, engineering pile
Face is produced fracture, while interior bar 41 relatively moves in outer tube 42；After the completion of autobalanced detection, pass through grouting pipe and ring
