A water stopping mechanism 4 is arranged in the mounting groove 3, and a wall scraping mechanism 5 is movably arranged below the water stopping mechanism 4. The wall scraping mechanism 5 clears the outer surface of the pile foundation casing 1, and meanwhile, the water stopping mechanism 4 is driven to seal a gap between the pile foundation casing 1 and the prefabricated bearing platform sleeve box 2. According to the invention, the water stopping mechanism 4 and the wall scraping mechanism 5 are arranged before hoisting, and the wall scraping mechanism 5 is used for scraping particles on the surface of the pile foundation pile casing 1 during hoisting, so that the friction between the pile foundation pile casing 1 and the water stopping mechanism 4 during working is reduced, and the water stopping function is continuously realized in the hoisting process by matching with the water stopping mechanism 4. After reaching appointed hoisting position, the inside of prefabricated cushion cap pouring box 2 remains dry construction environment all the time, and the prefabricated cushion cap pouring box can not gush water in, consequently need not to carry out the action of drawing water again, has saved time and the pouring quality of follow-up concrete pouring.
Further, the upper end and the lower end of the mounting groove 3 are provided with step surfaces, and the diameter of the mounting groove 3 is larger at two ends and smaller in the middle.
The water stop mechanism 4 comprises an elastic capsule 41, the elastic capsule 41 is installed in the installation groove 3 and is matched with the installation groove 3 in shape, annular limiting plates 42 are fixed on the upper end face bolt or the lower end face bolt or the screw of the installation groove 3, the outer diameter of the limiting plate 42 located below is larger than that of the limiting plate 42 located above, a limiting groove 43 is formed in the limiting plate 42 located below, and the bottom of the elastic capsule 41 is filled in the limiting groove 43. The limiting plate 42 is formed by splicing two halves and fixing the two halves through bolts, so that the follow-up dismantling work is facilitated.
The wall scraping mechanism 5 is positioned in the limiting groove 43 to seal the bottom of the elastic capsule 41.
Further, the wall scraping mechanism 5 comprises an annular cutter 51, the annular cutter 51 is fixed on an annular seat 52 through bolts or screws, and the annular cutter 51 is sleeved on the outer surface of the pile foundation casing 1. The annular seat 52 is fixedly connected with a protrusion 53, the protrusion 53 is embedded with balls for reducing friction force with the spiral groove 54, the inner wall of the limit groove 43 is provided with the spiral groove 54, and the protrusion 53 is matched with the spiral groove 54. The annular cutter 51 and the annular seat 52 are formed by splicing two halves and fixing the two halves through bolts, so that the subsequent dismantling work is facilitated.
When the annular cutter 51 moves up against resistance, the annular seat 52 and the protrusion 53 are in spiral rising movement under the action of the matched spiral groove 54, and the annular seat 52, the protrusion 53 and the annular cutter 51 are in spiral rising movement.
In the invention, during installation, the formed elastic capsule 41 is firstly placed in the installation groove 3, and then two limiting plates 42 are respectively fixed on the upper surface and the lower surface of the prefabricated bearing platform sleeve box 2 through screws or bolts, so as to limit the elastic capsule 41. The lower limiting plate 42 has a larger size, and the limiting groove 43 is formed in the lower limiting plate, so that the annular seat 52 and the annular cutter 51 penetrate out of the limiting groove 43, and the annular cutter 51 extends out. And pressurized liquid or gas is input into the elastic capsule 41 through a liquid inlet pipe communicated with the elastic capsule 41, so that the elastic capsule 41 is expanded. Due to the limitation of the limiting plate 42 and the annular seat 52, the elastic capsule 41 firstly pushes the annular seat 52 to the bottommost part until the annular seat cannot be pushed, and then extends to the gap between the pile foundation casing and the prefabricated bearing platform sleeve 2 to form a primary sealing state. During hoisting, the annular cutter 51 is sleeved with the pile foundation casing 1 after being aligned, then the annular cutter 51 starts to descend under the dead weight of the prefabricated bearing platform sleeve box 2, the annular cutter 51 descends along the pile foundation casing 1 and shovels particulate matters on the surface of the pile foundation casing 1, the outer surface of the pile foundation casing 1 becomes smooth again, and friction between the elastic capsule 41 and the pile foundation casing 1 is reduced. Therefore, the elastic capsule 41 cannot be easily rubbed and damaged, and a lasting water stopping effect is maintained, so that the inside of the prefabricated bearing platform sleeve box 2 is always in a dry construction environment, bearing platform concrete pouring can be performed after the installation of the specified position is completed, and the construction time is saved.
The limiting groove 43 and the mounting groove 3 are communicated to form a larger L-shaped section, so that the deformation allowance of the elastic capsule 41 is increased.
The particulate matter encountered by the annular cutter 51 will cause a certain resistance thereto, and the seawater will also cause a certain resistance and act on the annular seat 52 during the entire downward movement. Therefore, the annular cutter 51 and the annular seat 52 can move upwards to squeeze the elastic capsule 41 after being blocked, the upper and lower positions of the elastic capsule 41 are limited by the limiting plate 42 and the annular seat 52 and can only be tightly deformed towards the pile foundation casing 1, so that the contact area with the pile foundation casing 1 is increased, and the water stopping effect is further enhanced. The wall scraping mechanism 5 is matched with the water stopping mechanism to enhance the water stopping performance of the wall scraping mechanism, the inside of the prefabricated bearing platform sleeve box 2 is always in a dry construction environment, bearing platform concrete pouring can be carried out after the installation of the specified position is completed, and the construction time is saved.
Because the bulge 53 on the annular seat 52 and the spiral groove 54 arranged in the limit groove 43 are matched with each other, the track of the annular cutter 51 and the annular seat 52 moves upwards under the action of resistance is spiral, and the spiral annular cutter 51 has a stronger shoveling effect on the particulate matters on the pile foundation casing 1.
If the resistance is lost or reduced, the elastic capsule 41 pushes the annular seat 52 and the annular cutter 51 to reset, and the process is repeated.
Further, the outer wall surface of the annular cutter 51 forms an arc transition surface 55, and the wall thickness of the annular cutter 51 gradually decreases from top to bottom.
A plurality of obliquely arranged scrapers 56 are welded on the inner side surface of the annular cutter 51. The scraper 56 that the slope set up can carry out the secondary and eradicate after annular cutter 51's edge of a knife eradicates to strengthen the eradicate effect on pile foundation pile casing 1 surface, make pile foundation pile casing 1 surface smoother, thereby reduce the resistance between elastic capsule 41 and the pile foundation pile casing 1, further guaranteed the stagnant water effect of elastic capsule 41, thereby make prefabricated cushion cap case 2 inside be in dry construction environment always, can carry out cushion cap concrete casting after reaching the assigned position installation, further saved the engineering time. The particulate matter scraped off by the annular cutter 51 can be guided to the outside by the arcuate transition surface 55.
Further, the pressurized liquid injected into the elastic capsule 41 is lubricating oil.
The intersection zone of the elastic capsule 41, the annular seat 52 and the pile foundation casing 1 is provided with a plurality of one-way liquid outlets 6, and one-way valves are arranged in the one-way liquid outlets 6. The elastic capsule 41 extrudes and sprays the liquid with pressure inside to the junction of the annular seat 52 and the pile casing 1 under the extrusion of the annular seat 52.
The elastic capsule 41 is extruded when the annular seat 52 is spirally lifted, and when the pressure inside the elastic capsule 41 exceeds the limit, the unidirectional liquid outlet 6 can spray a certain amount of lubricating oil. On the one hand, the pressure release effect is realized, the elastic capsule 41 is prevented from being broken due to overlarge pressure, and the water stop is invalid. On the other hand, because the unidirectional liquid outlet 6 is just in time arranged on the junction zone of the elastic capsule 41, the annular seat 52 and the pile foundation casing 1, the sprayed lubricating oil just in time lubricates the junction of the annular seat 52 and the pile foundation casing 1, and can circumferentially lubricate along with the action of spiral ascending, the lubrication area is increased, the sliding friction force between the elastic capsule 41 and the pile foundation casing 1 is further reduced, the water stopping effect of the elastic capsule 41 continuously acts, the dry construction environment inside the prefabricated bearing platform sleeve box 2 is ensured, and the time is saved for subsequent construction.
When the pressure of the lubricating oil in the elastic capsule 41 is insufficient, the lubricating oil can be replenished by a liquid supply pump (the replenishing is the prior art and will not be described in detail).
