Detailed Description
The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.
As shown in fig. 1-8, a steel sleeve box device for reinforcing a bridge foundation pile comprises a bottom plate 1 arranged on the upper surface of a bearing platform a, 2 end plates 2 respectively arranged at two end positions of the bottom plate 1, an inner side plate 3 arranged on the bottom plate 1 and connected with the two end plates 2, and an outer side plate unit 4 arranged on the bottom plate 1 and connected with the two end plates 2 and used for being in threaded connection with the bearing platform a.
In this embodiment, the bottom plate 1, the end plate 2, the inner side plate 3, and the outer side plate unit 4 may be a complete single plate or a spliced composite plate, and the inner splicing mode and the splicing mode between the whole plates may be a combination of a hole plate, a sealing strip and a bolt, so that the steel box device is ensured to have sufficient structural stability and sufficient sealing waterproof performance.
In addition, this steel bushing box device directly erects on the upper surface of cushion cap a, and through outside board unit 4 again with cushion cap a spiro union, therefore this steel bushing box device still has the installation firm, be difficult for shifting the advantage that drops.
Finally, the rectangular steel sleeve box device can ensure that the new bearing platform c has enough water retaining and soil retaining effects when pouring. In addition, the new bearing platform c can be directly poured on the original bearing platform a, or can be connected with the original bearing platform a after the steel sleeve box device is removed.
The base plate 1 is arranged on at least 2 bearing platforms a.
In this embodiment, the steel box assembly, together with the new platform c formed last, can have sufficient installation stability when the base plate 1 is erected on at least 2 platforms a.
In addition, the more the number of the bearing platforms a spanned by the steel box device is, the longer the steel box device is, and finally, a new longer bearing platform c and a new pile foundation e can be formed.
The length direction of the original bearing platform a is the transverse bridge direction, and the length direction of the new bearing platform c is the longitudinal bridge direction.
The inner plate 3 is closer to the bridge pier b than the outer plate unit 4.
In this embodiment, the installation position of the steel box device needs to avoid the bridge pier b, so that the outer plate unit 4 can also be screwed to the end surface of the bearing platform a.
The outer panel unit 4 includes an upper rectangular plate 401 provided on the bottom plate 1 and the end plate 2, a lower protruding orifice plate 402 provided on the bottom side of the upper rectangular plate 401, and bolts 403 provided on the lower protruding orifice plate 402 and used for connecting the cap a.
In this embodiment, the number and positions of the lower projecting orifice plates 402 on the single outer plate unit 4 correspond to the bearing platform a across which they cross.
The outer panel unit 4 further includes a cross plate 404 disposed on the bottom side of the lower protruding orifice plate 402 and configured to engage the lower surface of the platform a.
In this embodiment, the lower protruding orifice plate 402 and the transverse plate 404 form an "L-shaped" plate, so that the steel box set has a vertical limiting function on the bearing platform a, and further provides the installation stability of the steel box set.
On the other hand, the cross plate 404 may be screwed to the base a.
The outer panel unit 4 further comprises a water stop strip 405 arranged on the bolts 403 and located between the platform a and the lower protruding orifice 402.
In this embodiment, a single water stop strip 405 is transversely disposed, and a vertical row of water stop strips 405 is disposed on an end surface of the bearing platform a, so that it is ensured that an external water body is more difficult to enter the steel sleeve box device.
In addition, the water stop strip 405 can also be used between the spliced veneers of the steel sleeve box device and at the spliced edges of the 5 box body side plates.
And the 2 inner side plates 3 on the two sides of the bridge pier b are also provided with middle support rods 5.
In this embodiment, the steel box device may be a single rectangular box body, or may be two rectangular box bodies respectively located at two sides of the bridge pier b.
Thus, the intermediate support bar 5 can be connected to reinforce two different rectangular boxes.
The inner side plate 3 and the upper rectangular plate 401 on the same side of the bridge pier b are also provided with an inner supporting rod 6.
In this embodiment, the inner support rods 6 are used to individually reinforce one of the rectangular boxes. But at the same time it should be noted that the new platform c needs to avoid the inner support bars 6 during casting, so that the inner support bars 6 need to be positioned relatively high in a rectangular box.
And an inclined supporting rod 7 is further arranged between the bottom plate 1 and the inner side plate 3 and between the bottom plate 1 and the upper rectangular plate 401 on the same side of the bridge pier b.
In this embodiment, the inclined support rod 7 and the inner support rod 6 may be used alternatively or both, and the final purpose of both are consistent, so as to reinforce a rectangular steel sleeve.
On the other hand, the inner support bar 6 has the disadvantage that the new platform c cannot be too wide, which also requires to avoid the inner support bar 6.
The bottom plate 1 is also provided with an opening 8 for connecting the bearing platform a and the new bearing platform c, and the opening 8 is arranged on a splicing seam 9 of the bottom plate 1.
In this embodiment, in the entire pile lifting structure for reinforcing the bridge foundation, the new platform c needs to be connected to the platform a, and when the connection mode is a casting integrated mode, the opening 8 needs to be used, so that the new platform c is directly cast on the original platform a.
In addition, the splicing seam 9 is a single board splicing position of the bottom board 1, so that the opening 8 spans across the splicing seam 9, and the bottom board 1 can be smoothly removed after the new bearing platform c is poured.
Finally, an annular water stop strip 405 is further arranged at a position outside the opening 8, namely between the bottom plate 1 and the bearing platform a, so that a large amount of water leakage is difficult to occur at the opening 8.
On the other hand, when the connection mode is to be the connection after pouring, the opening on the bottom plate 1 is not needed, but when the bottom plate 1 needs to be removed, a new bearing platform c may need to be lifted upwards appropriately, so that the bottom plate 1 is pulled out to be removed.
The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various modifications may be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model. These are all non-inventive modifications which are intended to be protected by the patent laws within the scope of the appended claims.
