Description
Technical Field
The utility model relates to an underwater construction field especially relates to a stride sea or river bridge stagnant water capsule of being under water under construction.
Background
When the cross-sea or river bridge is constructed underwater, pile foundations need to be built to support the bridge; firstly, placing a caisson on a riverbed and placing a steel casing in a middle hole of the caisson on the pile foundation; then, a steel reinforcement cage is placed between the steel casing and the caisson, and concrete is poured. After the pile foundation is firmly fixed in water, a bearing platform and a pier can be built. Because the sealing performance between the steel casing and the caisson is poor, the reliability of subsequent construction is reduced.

The utility model provides a to above problem, provide a simple structure, convenient processing improves the sea of striding of leakproofness or river bridge stagnant water capsule of being under water construction.
The technical scheme of the utility model is that: comprises a ring-shaped bag body, one side of the bag body is provided with a metal nozzle,
the bag body is arranged between the caisson and the steel casing, the top of the caisson is open, a bottom plate of the caisson is provided with a middle hole, the caisson is arranged on a river bed, and the steel casing is arranged in the middle hole of the caisson;
the inner wall of the middle hole of the caisson is provided with an annular groove, the bag body is positioned in the annular groove,
the caisson is provided with a pipe cavity communicated with the annular groove, and a pipeline used for placing a metal nozzle communicated with the capsule body is arranged in the pipe cavity.
The steel casing penetrates through the middle hole of the caisson and extends into the riverbed.
The steel protects a section of thick bamboo and has a plurality of sections, and a plurality of sections steel protect a section of thick bamboo from the top down and pile up the setting in proper order.
Convex sealing ribs are arranged at the inner side and the outer side of the bag body at intervals.
The pipeline is used for inflating or filling water.
In the work of the utility model, a water-stopping capsule is arranged between the caisson and the steel casing to play the role of water-stopping and sealing; the gap water stopping is completed by inflating the bag body or expanding the volume before and after water filling, so that the subsequent reliable construction is facilitated.
During specific operation, when the bottom plate of the caisson is prefabricated, a water-stopping capsule placing space is reserved, and meanwhile, a capsule inflation or water filling path (namely a pipe cavity) is reserved; placing a water stopping capsule at a prefabricated position of the bottom plate, connecting a hose with an air or water way, and then placing the caisson to the water bottom; after the caisson is in place, the water stopping capsule is inflated or filled with water to realize expansion of the capsule, and the steel casing is attached to realize sealing. And pumping water in the caisson to finally realize normal construction operation in the caisson.
The utility model discloses easy to assemble, it is with low costs.
