thirdly, further fixing a telescopic protection mechanism:
the inner side filler 4 and the outer side filler 5 are synchronously and respectively filled in the foundation pit 10 on the inner side and the outer side of the protective bag belt 201, the outer side filler 5 of the inner side filler 4 extrudes two outer side walls of the protective bag belt 201 to enable the two side walls of the protective bag belt 201 to be close to each other, and in the process that the first reinforcing rib 215 and the second reinforcing rib 216 arranged in the protective bag belt are close to each other, the air cavity 214 inside the protective bag belt 201 is extruded, as shown in fig. 8, air in the air cavity 214 enters the sealed air bag 205 through the air holes 211 to enable the sealed air bag 205 to be propped open and is propped against the groove walls of the limiting groove enclosed among the reinforcement cage 102, the positioning pile 1 and the two separation plates 103, so that the sealed connection between the end part of the protective bag belt 201 and the positioning pile 1 is realized.
The protective bag belt 201 is further adopted to strengthen the sealing, because as shown in fig. 10, when the slot 101 of the positioning pile 1 is not aligned to the axis, under the pulling force of the protective bag belt 201 with the elastic function, the inserting part 204 can rotate around, for example, a in the figure as the center of a circle, so that the side of the arc inner supporting block 212 close to the positioning pile 1 is tilted to be difficult to realize the sealing, and the sealing air bag 205 can strengthen the sealing effect on the basis;
fourthly, recovering the device:
the water pipe is used again to connect the water filling port 304 on the protective bag belt 201, and water is filled into the water bag 301. At this time, the front and rear of the protective bag belt 201 are pressed by the inner packing 4 and the outer packing 5, and the water bag 301 inside thereof is hard to move up and down. Therefore, in the process of expanding the water bag 301, as shown in fig. 9, the front and rear side walls of the protective bag strip 201 are spread, so that the volume of the air chamber 214 is increased, the air flows out through the sealed air bag 205, the sealing of the sealed air bag 205 on the connecting part of the spud 1 is eliminated, and the lifting of the telescopic protective mechanism 2 is easier due to the reduction of friction.
According to the invention, through the matching among the positioning pile 1, the telescopic protection mechanism 2 and the side support mechanism 3, the telescopic protection mechanism 2 can be quickly installed between the slots 101 of the positioning pile 1 which is roughly positioned by injecting water into the water bag 301, and vertical support can be formed automatically after water drainage; after filling materials are filled into the two sides of the telescopic protection mechanism 2, the air chamber 214 in the protection bag belt 201 is extruded to inflate the sealing air bag 205 of the inserting part 204, so that the sealing between the inserting part 204 and the positioning pile 1 is further realized, the installation and recovery efficiency of the water stopping device is improved on the whole, and the water stopping effect is good.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention.
