Go up support frame 1 including last tripod body 11, the three edge of going up tripod body 11 all is provided with support tube 12, go up the first slide of support tube 12's bottom seted up with 3 looks adaptations of telescopic link. Lower carriage 2 includes tripod body 21 down, the three edge of tripod body 21 all is provided with bottom suspension stay 22 down, the second slide with 3 looks adaptations of telescopic link is seted up at bottom suspension stay 22's top. As shown in fig. 1, the overall structure of the lower support frame 2 is substantially the same as that of the upper support frame 1, because the lower support frame 2 is installed at the bottom of the corrugated pipe, it is necessary to weld a frame body at the bottom of the lower support frame 2, so that the bottoms of the three lower support pipes 22 are welded together, and the bottom surface is flat and can stand vertically. The triangular frame bodies of the upper support frame 1 and the lower support frame 2 can be fixed and propped against the inner wall of the corrugated pipe through three positions, and can also be directly used when the top plate mechanism 4 is not used, the positions of the three upper support pipes 12 correspond to those of the three lower support pipes 22, and as shown in fig. 2 and 3, the three outer walls of the support pipes just contact with the inner wall of the corrugated pipe.

The both ends of telescopic link 3 are connected, three with last supporting tube 12 and bottom suspension fagging pipe 22 respectively the surface of telescopic link 3 all is provided with a plurality of locating holes 31, the surface of going up supporting tube 12 and bottom suspension fagging pipe 22 is provided with the countersunk head screw hole 32 with locating hole 31 looks adaptation, the inside of countersunk head screw hole is provided with the bolt of fixed telescopic link 3. The both ends of telescopic link 3 are inserted respectively in the first slide of upper support tube 12 and the second slide of lower support tube 22, make upper support tube 12 and lower support tube 22 connect, as shown in fig. 1, bolt fastening telescopic link 3 is passed through to the inside of countersunk head screw hole 32, when adjusting length, can pass through the locating hole 31 of bolt fastening different positions. The countersunk holes 32 may prevent the bolts from rising above the surface of the upper and lower support tubes 12, 22 and may prevent the bolts from jamming when installed in the bellows.

The top of the three upper supporting tubes 12 is provided with a connecting block 14, and the bottom of the three lower supporting tubes 22 is provided with a connecting groove 15 matched with the connecting block 14. When the corrugated pipe is longer and is larger than the extension range of the telescopic rod 3, the two brackets can be integrally fixed through the connecting block 14 and the connecting groove 15, and the use can be lengthened.

The top plate mechanism 4 comprises three arc-shaped plates 41 which are arranged up and down, the back surfaces of the arc-shaped plates 41 are provided with symmetrical tension springs 42, the middle position of the back surfaces of the arc-shaped plates 41 is provided with an ejector rod 43, the ejector rod 43 penetrates through the upper support frame 1 and extends to the inside of the adjusting hole 13, and the inside of the adjusting hole 13 is further provided with a T-shaped limiting block 16. The loop bar 5 comprises an outer bar 51, an inner bar 52 is inserted into the outer bar 51, a positioning bar 53 is inserted into the inner bar 52, and a positioning groove 54 matched with the T-shaped limiting block 16 is formed in the positioning bar 53. The extension spring 42 will pull the arc plate 41 to approach the adjusting hole 13, as shown in fig. 3, when the loop bar 5 is not used, two ends of the arc plate 41 will butt against the upper supporting tube 12, the arc plate 41 will not contact the inner wall of the corrugated tube, only three upper supporting tubes 12 will contact the inner wall of the corrugated tube, at this time, the bracket is convenient to take out and install, when the loop bar 5 is inserted, the loop bar 5 will butt against the ejector rod 43, the ejector rod 43 will be pushed outwards, the arc plate 41 will approach the inner wall of the corrugated tube, the diameter of the positioning rod 53 is minimum and the distance of the ejector rod 43 is also minimum, next, the inner rod 52, and finally, the outer rod 51 is slightly smaller than the diameter of the adjusting hole 13, the ejector rod 43 can be completely pushed out, at this time, the arc plate 41 just contacts the inner wall of the corrugated tube, and the three arc plates 41 and the three upper supporting tubes 12 can form a circle similar to the inner wall of the corrugated tube. After the inner rod 52 and the positioning rod 53 are used, the three arc-shaped plates 41 do not contact with the inner wall of the corrugated pipe, a certain distance is reserved, the support can be taken out conveniently in actual use, and deformation of the corrugated pipe can be controlled when cement is poured on the outer side.

When the loop bar 5 is used, the positioning rod 53 is used, the inner rod 52 is added to the positioning rod 53, and the outer rod 51 is added to the positioning rod 53 and the inner rod 52, and the number of the arc plates 41 is three for each surface, so that the end of the push rod 43 needs to be an inclined surface or a tapered surface in order to prevent the push rod 43 from pushing against the loop bar 5, and when the loop bar 5 is downward, the push rod 43 can be pushed outward by contacting the inclined surface or the tapered surface. In order to adjust the overall length of the support conveniently, standard distance scales need to be added on the telescopic rod 3.

When the simple support suitable for the prestressed continuous box girder corrugated pipe is used, the length of the whole support is adjusted according to the length of the corrugated pipe, the length of the support is slightly larger than that of the corrugated pipe, then the support is integrally installed in the corrugated pipe, the loop bar 5 needs to be taken out during installation, the lower supporting pipe 22 is arranged at the bottom, and then the loop bar 5 is used according to requirements.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
