Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 5, in an embodiment of the present invention, a grouting flexible conduit for grouting and repairing a minimally invasive crack of a bridge includes a first conduit 1 and a second conduit 2 located at one end of the first conduit 1, where the first conduit 1 and the second conduit 2 are both the same conduit, and the number of the conduits may be multiple, because the length of the whole conduit is extended. The surface activity cover of second pipe 2 is equipped with annular piece 3, spout 4 has been seted up to one side of annular piece 3, the top of annular piece 3 has been seted up and has been changeed the hole, it is linked together with spout 4 to change the hole, annular piece 3 rotates through changeing the hole and is connected with threaded rod 5, annular piece 3 has slider 6 through 4 sliding connection of spout, the thread groove has been seted up on slider 6, threaded rod 5 passes through thread groove and 6 threaded connection of slider, rotate threaded rod 5 this moment, can drive slider 6 upwards or remove downwards. One side of the sliding block 6 is fixedly connected with a moving plate 7, and the moving plate 7 is used for extruding the second guide pipe 2, so that the second guide pipe 2 is pressed to deform, and the second guide pipe 2 can be conveniently inserted into a bridge crack.

Two fixed plates 8 of one side fixedly connected with that the movable plate 7 is close to second pipe 2, fixedly connected with dead lever 9 between the relative one side of two fixed plates 8, the movable sleeve is equipped with rotating pipe 10 on the dead lever 9, rotating pipe 10 is located between movable plate 7 and the second pipe 2, when movable plate 7 moves down, movable plate 7 can drive rotating pipe 10 and extrude second pipe 2, thereby make second pipe 2 flatten, drag second pipe 2 this moment, rotating pipe 10 also can follow the rotation when making second pipe 2 remove, and then reached the effect that reduces the frictional force that second pipe 2 received at the removal in-process.

The first sealing sleeve 11 is movably sleeved on the first guide pipe 1 and the second guide pipe 2, and the first sealing sleeve 11 is utilized to help prevent cement paste in the first guide pipe 1 and the second guide pipe 2 from seeping out through the joint of the first guide pipe 1 and the second guide pipe 2. The equal fixedly connected with a plurality of annular plates 12 in one side opposite of first pipe 1 and second pipe 2, and the equal one-to-one of annular plate 12 on first pipe 1 and the second pipe 2, equal fixedly connected with buckle 13 on the annular plate 12 that corresponds on first pipe 1 and the second pipe 2 utilizes buckle 13 to connect first pipe 1 and second pipe 2. The movable sleeve is equipped with second seal cover 14 on buckle 13, and second seal cover 14 is used for protecting buckle 13, avoids as far as possible when the junction of first pipe 1 and second pipe 2 gets into the bridge crack inside, and buckle 13 is scraped by the pontic, helps avoiding buckle 13 to break off, has avoided second pipe 2 to break away from first pipe 1 as far as possible and is inconvenient to take out from the bridge crack inside.
