Description
Technical Field
The utility model relates to a cushion cap construction technical field under water specifically indicates a quick plugging device of steel hanging box bottom plate.
Background
The construction of the bridge deepwater bearing platform usually adopts a steel hanging box cofferdam, the core technology and the difficulty are that the sealing and water stopping of a gap between a steel hanging box bottom plate and a steel protecting cylinder are realized, at present, two conventional methods are adopted, one is that after the steel hanging box is put in place, a layer of bottom sealing concrete is poured on the steel hanging box bottom plate; and in the other type, an annular air bag is designed between the steel casing and the bottom plate, and the air bag is inflated after the hanging box is put in place, so that the gap is sealed. However, both the two methods have certain problems, the volume of the plugging concrete needed when the bottom sealing concrete is poured and plugged is large, the cost is high, and the concrete equal strength time is needed to be longer; by adopting the air bag plugging method, the air bag is easy to slide under the action of buoyancy, and meanwhile, the air bag is easy to leak air due to self or external factors, so that the sealing property is poor and the process is complex.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the deficiencies of the prior art, providing a realize quick sealing and the quick plugging device of steel crane bottom plate that sealing performance is good.
In order to achieve the above object, the utility model provides a quick plugging device of steel hanging box bottom plate, its characterized in that: the sealing ring plate comprises a second ring plate and a first ring plate, wherein the second ring plate is in compression fit with the steel casing, the first ring plate is in compression fit with a bottom plate of a steel crane, and flexible sealing gaskets are arranged between the second ring plate and the steel casing and between the first ring plate and the bottom plate of the steel crane.
Further, the sealing ring plate is formed by splicing a plurality of sections of sector plates in sequence, each sector plate comprises a first sector plate in press fit with the bottom plate of the steel crane, and the first sector plate is close to one end of the steel protective cylinder and is fixedly connected with an arc plate.
Furthermore, the two ends of each first sector plate are fixedly connected with connecting lug plates, and the connecting lug plates between the adjacent first sector plates are fixedly connected through connecting bolts.
Further, be equipped with on the steel overhead bin bottom plate with the backing plate of first sector plate isotachy, the backing plate with first sector plate upper end is equipped with the clamp plate, it has the regulation hole to open on the clamp plate, be located on the steel overhead bin bottom plate first sector plate with still fixed the fastener bolt of having buried underground between the backing plate, the fastener bolt other end passes regulation hole and adjusting nut screw-thread fit.
The utility model has the advantages that: realize quick sealed and sealing performance is good. The utility model discloses a set up the sealed crown plate and protect a section of thick bamboo and steel crane bottom plate tight fit with the steel respectively, all be equipped with waterproof flexible sealing pad between a section of thick bamboo and steel are protected to first sector plate and steel and between arc plate and the steel crane bottom plate. Therefore, the possibility that water passes through a gap between the steel casing and the bottom plate of the steel crane box is completely prevented from both radial and axial directions, the sealing performance is good, the structure is simple, and sealing can be realized after field installation is completed.
Drawings

Fig. 2 is a top view of the present invention.
Fig. 3 is a structural schematic diagram of a sector plate.
The components in the figures are numbered as follows: the steel protects a 1, steel hanging box bottom plate 2, sealing ring plate 3, first crown plate 31, second crown plate 32, first sector plate 301, circular arc board 302, connection otic placode 303, backing plate 4, clamp plate 5, regulation hole 501, flexible sealing pad 6, connecting bolt 7, fastening bolt 8, adjusting nut 9.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, which are not intended to limit the scope of the present invention.
As shown in figures 1-3, a quick plugging device of steel hanging box bottom plate, its characterized in that: including the overcoat sealed crown plate 3 on steel protects a 1, sealed crown plate 3 includes and protects a 1 bearing fit's second crown plate 32 with the steel, still includes and protects a 1 bearing fit's first crown plate 31 with steel hanger bottom plate 2, all is equipped with flexible sealing gasket 6 between second crown plate 32 and the steel and protects between 1 and between first crown plate 31 and the steel hanger bottom plate 2, and flexible sealing gasket is the rubber pad, and waterproof performance is good. Therefore, the flexible sealing gasket is compressed by the first annular plate in the axial direction and is compressed by the second annular plate in the radial direction, and the gap between the steel casing and the bottom plate of the steel crane is respectively blocked by the flexible sealing gasket in the radial direction and the axial direction, so that the waterproof performance is good.
Among the above-mentioned technical scheme, seal ring board 3 is formed by the concatenation in proper order of multistage sector plate, and the sector plate includes the first sector plate 301 with steel crane bottom plate 2 press fit, and first sector plate 301 leans on steel to protect 1 one end fixedly connected with circular arc board 302 of a section of thick bamboo. The two ends of the first sector plates 301 are fixedly connected with connecting lug plates 303, and the connecting lug plates 303 between the adjacent first sector plates 301 are fixedly connected through connecting bolts 7. Like this, the concatenation of whole seal ring board is realized through the connection of connecting the otic placode on the adjacent first sector plate, simultaneously, can make circular arc board and flexible sealing pad and steel protect a section of thick bamboo outer wall to compress tightly through adjusting connecting bolt's fastening degree.
