For further specifying above-mentioned purpose of the present utility model, design feature and effect, the utility model is described in detail below with reference to accompanying drawing.
Description of drawings
Fig. 1 is the cross-sectional view strength of first embodiment of box culvert deviation correcting device of the present utility model;
Fig. 2 is the vertical view of the box culvert deviation correcting device among Fig. 1;
Fig. 3 is the cross-sectional view strength of second embodiment of box culvert deviation correcting device of the present utility model.
The specific embodiment
To describe preferred embodiment of the present utility model in detail now, although the employed term in back is to select from public term, but some term then is the applicant to be judged by it and selects, and its detailed meanings should be understood according to the spirit that the application's desire discloses.
As depicted in figs. 1 and 2, the existing median plane 901 off-design median planes 902 of box culvert 90, box culvert deviation correcting device 1 among first embodiment of the present utility model is used for box culvert 90 is passed to design centre face 902 from existing median plane 901, and it comprises the first Larsen stake 10, back beam 20, a plurality of oil top 50, at least one first pad 40.The first Larsen stake 10 be arranged on box culvert 90 away from first side of design centre face 902 and with first side at a distance of predetermined distance.Back beam 20 is parallel to first side 910 of box culvert 90 and is close to the first Larsen stake 10, and is fixed in the bottom surface, ground.A plurality of oil top 50 is a brace foundation with back beam 20 all, can be flexible to first side 910 of box culvert 90.First pad 40 is close to first side 910 of box culvert 90.When box culvert was passed, a plurality of oil top 50 was stretched to first pad 40 and box culvert 90 is passed to design centre face 902 from existing median plane 901.
When finding box culvert 90 off normals, the first Larsen stake 10 is inserted earlier and is beaten near first side 910 of box culvert 90, excavate the earthwork between the box culvert 90 and the first Larsen stake 10 then, other component and fitting of the last space mounting box culvert deviation correcting device 1 that forms in the earthwork back of excavating, the first Larsen stake 10 both can be the stake of original bracing of foundation pit Larsen, also can be to insert the Larsen steel sheet pile of beating again.
Change example as one of present embodiment, box culvert deviation correcting device 1 can not comprise steel I-beam 30, but back beam 20 should be enough thick.At this moment, for oil top 50 more abundant with contacting of back beam 20, can oil push up 50 and back beam 20 between second pad is set, each oil top 50 corresponding one second pad, perhaps all second microscler pads of oil top 50 correspondences.
As shown in Figure 2, all oil tops 50 are arranged in parallel based on steel I-beam 30 and are controlled by same hydraulic cabinet 51, and in the present embodiment, hydraulic cabinet 51 is by all oil tops 50 of oil pipe line 501 controls.Each oil top 50 corresponding one first pad 40, in fact, first pad, 40, the first pads 40 that a plurality of first pads 40 in Fig. 2 can be merged into a strip can be the thick steel plates of 10mm.
Protect the building on the ground surface of second side of box culvert 90 if desired, second Larsen stake 10 ', the second Larsen stake 10 ' and second side 911 can also be set in second side 911 of the contiguous design centre of box culvert 90 face 902 at a distance of default distance.
Fig. 3 shows second embodiment of box culvert deviation correcting device of the present utility model, maximum different being included between oil top 50 and the back beam 20 of box culvert deviation correcting device 2 and box culvert deviation correcting device 1 is provided with a plurality of parallels 60, the situation when the top journey that box culvert deviation correcting device 2 is mainly used in oil top 50 is not enough to finish the correction of box culvert 90.
Going on to say the mounting means of a kind of above-mentioned box culvert deviation correcting device 1 and/or 2 below, but it should be noted that, is in order to make those skilled in the art understand the utility model rather than in order to limit the utility model to the explanation of this mounting means.
At first, insert in first side 910 of box culvert 90 and to play the first Larsen stake 10 (or utilizing the stake of original bracing of foundation pit Larsen), if necessary, also should be simultaneously play the second Larsen stake 10 ' in that second side 911 is slotting.
Then, excavate the earthwork between box culvert 90 and Larsen stake 10 or 10 ', at Larsen stake 10 limit fluid concrete back beams 20 or other beam body is installed, separate with asphaltic felt between back beam 20 and the Larsen stake 10.
Secondly, oil top 50 and operation panel 51 are installed, are laid steel I-beam 30 (if necessary) between oil top 50 and back beam 20, lay steel plate (first pad 40) between oil top 50 and box culvert 90, oil top 50 all is arranged in parallel.
At last, start oil top 50, push up the correction that 50 1 top journeys are not enough to finish box culvert 90 as oil, behind 50 retractions of oil top, push up 50 behind top iron 60 at oil, the oil top 50 that reruns arrives design attitude until box culvert 90.
Though the utility model discloses as above with preferred embodiment; yet it is not in order to limit the utility model; anyly be familiar with one of ordinary skill in the art; in not breaking away from spirit and scope of the present utility model; therefore should make the variation or the replacement of all equivalences, protection domain of the present utility model is when looking accompanying being as the criterion that the application's claim scope defined.
