Description
Technical Field
The utility model relates to a bridge construction field, especially a quick plugging device of steel hanging box.
Background
In the deep water bridge construction process, a steel suspension box cofferdam is usually adopted to provide dry construction conditions for the abutment. The technical difficulty lies in that a certain gap needs to be reserved between the bottom plate and the steel casing for ensuring the smooth transfer of the steel hanging box, the gap is difficult to block in the construction process, and the blocking quality can directly influence the construction of the subsequent abutment.
The commonly used plugging modes at present are as follows: 1. after the steel hanging box is put down in place, an annular steel plate is used for plugging a gap between the bottom plate and the steel casing, and then bottom sealing concrete is poured. 2. Before the hanging box is transferred, an annular air bag is arranged on the bottom plate, and after the air bag is transferred to the designed elevation along with the hanging box, the air bag is inflated or filled with mortar for blocking. For the method 1, large-area underwater concrete pouring is needed, the thickness of the back cover is generally required to be at least 1m, and the cost is high; meanwhile, when pouring, the plugging plate topples or gaps are not tightly plugged, slurry leakage and the like are easy to occur, and plugging failure is caused. For scheme 2, the situations of air bag displacement or abrasion and the like are very easy to happen in the process of lowering the hanging box, air leakage and slurry leakage are caused during plugging, and therefore effective plugging cannot be formed. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed can improve the efficiency of construction greatly, reduces the quick plugging device of steel hanging box of the construction degree of difficulty and cost.
The technical solution of the utility model is that: the utility model provides a quick plugging device of steel hanging box which characterized in that: plugging device include an annular steel sheet 1, be connected with rubber circle 2 on annular steel sheet 1, 2 sections of rubber circle are right trapezoid shape, have seted up bolt hole 3 on annular steel sheet 1, and with bolt hole 3 is furnished with high strength bolt 4, then is provided with a plurality of rings 5 of evenly distributed on the circumferencial direction on the terminal surface of rubber circle 2, simultaneously the internal diameter and the external diameter of annular steel sheet 1 are greater than the internal diameter and the external diameter of rubber circle 2 respectively, just the bolt hole is seted up at annular steel sheet 1 and the non-overlapping part of rubber circle 2 department.
Compared with the prior art, the utility model, have following advantage:
the quick plugging device for the steel suspension box with the structural form is simple in structure, ingenious in design and reasonable in layout, and aims at solving the problem that the traditional plugging device or method for the steel suspension box leaks violently in the actual working process, a special plugging structure is designed, the special plugging structure mainly comprises an annular steel plate and a rubber ring which are connected with each other, after the device is sleeved outside a steel protective cylinder, the rubber ring with the special shape on the special plugging structure can be extruded at an annular gap between a bottom plate of the steel suspension box and the steel protective cylinder, and the plugging device can be extruded in the gap by utilizing water pressure or a high-strength bolt, so that quick and reliable plugging is realized. The plugging device has the advantages that the working efficiency can be improved and the overall labor capacity of workers can be reduced on the premise of ensuring the plugging effect, the manufacturing process is simple, and the manufacturing cost is low, so that the plugging device has various advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.

Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 to 3: the utility model provides a quick plugging device of steel hanging box, it includes an annular steel sheet 1, is connected with rubber circle 2 on annular steel sheet 1, 2 sections of rubber circle are right trapezoid shape, have seted up bolt hole 3 on annular steel sheet 1, and with bolt hole 3 is furnished with high strength bolt 4, then is provided with a plurality of rings 5 of evenly distributed on the circumferencial direction on the terminal surface of rubber circle 2, simultaneously the internal diameter and the external diameter of annular steel sheet 1 are greater than the internal diameter and the external diameter of rubber circle 2 respectively, just the bolt hole is seted up at annular steel sheet 1 and the non-overlapping part of rubber circle 2 and is located.
The utility model discloses quick plugging device of steel hanging box's working process as follows: when underwater construction is carried out (as shown in fig. 2), firstly, the whole steel hanging box is sleeved on the steel casing and is placed to the designed elevation, at the moment, a gap exists between the bottom plate 6 of the steel hanging box and the steel casing, the inner diameter of the inner hole of the bottom plate 6 is made into a shape matched with the section of the rubber ring 2 in advance, then the annular steel plate 1 is connected onto the bottom plate 6 through the high-strength bolts 4, the rubber ring 2 bears downward force in one direction along with the gradual screwing of the high-strength bolts 4, and is gradually extruded into the gap between the bottom plate 6 and the steel casing, namely, the sealing effect is ensured by the pressure applied to the rubber ring 2 by the bottom plate 6, and the purpose of rapid and reliable plugging is achieved.
When the water construction is carried out (as shown in fig. 3), firstly, the plugging device is sleeved on a steel protective cylinder, then a steel wire rope 7 is connected on a lifting ring 5 on the top end face of the steel protective cylinder, the top end of the steel wire rope 7 is connected on a steel corbel 9 on the top of the steel protective cylinder through a chain block 8, then a steel hanging box is placed to a designed elevation, a gap exists between a bottom plate 6 of the steel hanging box and the steel protective cylinder, the plugging device is positioned below the steel hanging box, the inner diameter of an inner hole of the bottom plate 6 is made into a shape matched with the section of the rubber ring 2 in advance, and then the device is lifted by the chain block 8 to enable the rubber ring 2 to be squeezed into the gap between the bottom plate 6 and the steel protective cylinder; along with pumping water in the cofferdam, the water body above the bottom plate 6 is gradually reduced until emptying, at the moment, the annular steel plate 1 bears upward water pressure in the direction, and the rubber ring 2 is pressed in a gap, so that the aim of rapid and reliable plugging is fulfilled.
