The present application is described in further detail below with reference to figures 1-3.
Aiming at the existing floating body monitoring method, an operator needs to put the floating bodies 1 into the pre-dug holes 12 one by one, and before putting the floating bodies 1, the operator usually needs to fill soil 13 first to control the installation depth of the floating bodies 1 to be put; because the operation window is less, and the operation passageway is comparatively long and narrow, when the operator need put body 1 to accurate height, often need consume longer time and energy, have the higher problem of the operation degree of difficulty promptly.
The embodiment of the application discloses body installation device.
Example 1:
referring to fig. 1, the installation device of the floating body 1 comprises a sleeve 2, a base 3 abutting against the lower end of the sleeve 2, and a plurality of pull ropes 4 positioned outside the sleeve 2, wherein one end of each pull rope 4 is connected to the base 3, and the other end of each pull rope 4 extends to the upper end of the sleeve 2. The casing 2 comprises a plurality of sections of unit pipes 21 which are sequentially spliced along the axial direction of the casing 2.
An operator can stand the first unit pipe 21 on the upper surface of the base 3 and put the floating body 1 and the soil material 13 into the first unit pipe 21, and simultaneously control the height of the floating body 1 in the sleeve 2 to be a proper value by virtue of the filling property of the soil material 13; then, installing a second unit pipe 21 at the upper end of the first unit pipe 21, completing filling of the floating body 1 and the soil material 13 in the unit pipe 21, and completing installation and setting of the remaining unit pipes 21, the floating body 1 and the soil material 13 in the same way; then fixing the other ends of the pull ropes 4 at the upper end of the sleeve 2 in a binding manner and the like so as to realize the tight abutting of the base 3 and the sleeve 2; an operator digs out the pre-digging hole 12, conveys the sleeve 2 and the base 3 to the pre-digging hole 12, puts the sleeve into the pre-digging hole 12 and puts the base 3 at the lower end of the sleeve 2; after the insertion is completed, the pulling rope 4 is unfastened, and the sleeve 2 is taken out from the pre-dug hole 12.
Through the arrangement, one point is that all the floating bodies 1 and the soil 13 arranged among the floating bodies 1 can be integrally placed into the pre-dug holes 12, so that the placing efficiency is improved; more importantly, the sleeve 2 is spliced, so that the operation channel is shortened, and the floating body 1 can be accurately and easily placed to a proper height and a proper shape, so that the operation difficulty is reduced.
It is worth to be noted that the splicing mode between the adjacent unit pipes 21 can be a threaded connection, and can also be other detachable connection modes; when the adjacent unit pipes 21 are connected by threads, an annular groove is formed in the inner side of the upper port of the unit pipe 21 close to the lower end, a first thread is arranged on the wall of the annular groove, an annular groove is also formed in the outer side of the lower port of the adjacent unit pipe 21 close to the upper end, a second thread is arranged on the wall of the annular groove, and the first thread and the second thread can be in threaded fit; when two adjacent unit pipes 21 are spliced, the spliced part of the two adjacent unit pipes 21 has no obvious bulge or dent, so that the outer wall and the inner wall of the sleeve 2 are as flat as possible along the axial direction of the sleeve 2.
It should be noted that the soil 13 filled in the casing 2 should be selected to be a specific soil 13, so that after the casing 2 is embedded in the pre-dug hole 12, the soil 13 inside the casing 2 is matched with the soil 13 outside the casing 2 in height, so as to restore the soil quality at the position to the maximum extent and improve the accuracy of the flushing monitoring.
In this embodiment, the number of the pulling ropes 4 may be two, but is not limited to two, and the plurality of pulling ropes 4 extending to the upper end of the sleeve 2 may be bound to each other. The one end that base 3 was kept away from to stay cord 4 is connected with the counter weight body 5, and the value of counter weight body 5 lies in: when an operator unwinds the pull rope 4 and removes the sleeve 2, the counterweight body 5 can drive the end part of the pull rope 4 to descend to the lower position of the pre-dug hole 12, even the bottom of the pre-dug hole, and the pull rope 4 is not easy to float outwards along with the flow of the water body in the later stage of flushing, so that the probability that the pull rope 4 is wound with sundries flowing in the water body to pull the base 3 to deviate is reduced; the weight body 5 can be selected as a metal block with higher density.
Be provided with a plurality of groups wire ring group on the sleeve pipe 2 outer wall, the group number of wire ring 6 equals the quantity of stay cord 4 to the one-to-one, a set of wire ring group that stay cord 4 passed the correspondence, wire ring 6 are used for restricting the position of stay cord 4, and direction stay cord 4 makes the fixed sleeve pipe 2 upper end department that can be more stable of stay cord 4 upper end. The number of the wire rings 6 of each wire ring group can be selected to be multiple, and at least one wire ring 6 is arranged on the outer wall of each optional unit tube 21; the inner diameter of the wire guide ring 6 is larger than the outer diameter of the counterweight body 5 so as to allow the counterweight body 5 to pass through the wire guide ring 6; the wire loop 6 may be provided to protrude from the outer wall of the casing 2 or the wire loop 6 may be formed by making a hole in the outer wall of the casing 2.
The inner diameter of the sleeve 2 is gradually reduced from the lower end to the upper end, and is roughly in a tower shape, so that when an operator needs to take the sleeve 2 out of the pre-dug hole 12, the inner wall of the sleeve 2 in the tower shape can reduce the touch influence of the sleeve 2 on soil materials 13 and the floating body 1 in the sleeve 2, and meanwhile, the taking-out difficulty of the sleeve 2 is also reduced.
The outer fringe of base 3 upper surface is opened there is the ladder annular, and the lower extreme port inboard of sleeve pipe 2 is opened and have the cooperation annular with ladder annular complex, and under the cooperation of ladder annular and cooperation annular, sleeve pipe 2 and base 3 can the complex more accurate, stable.
