Problems solved by technology
Existing water-stop capsule products are mostly molded by multiple parts and then hot-vulcanized joints or glue cold-bonded to realize the closed capsule structure, but this kind of molding process is complicated and cumbersome, and the product has weak performance areas, and the air pressure it can withstand is generally not high. more than 0.1MPa

Embodiment 1
[0046] A water-stopping capsule of the present invention, such as figure 1 with figure 2 As shown, the water-stop capsule has a ring-shaped structure (ring-shaped hollow), and the water-stop capsule is provided with an inflatable nozzle 14. The water-stop capsule includes an inner rubber layer 11, a reinforcement layer 12 and an outer rubber layer 13. The reinforcement layer 12 is located on Between the inner rubber layer 11 and the outer rubber layer 13 .
[0047] In this embodiment, the reinforcing layer is made of reinforcing material, and the reinforcing material is a cord (canvas is also acceptable) woven from reinforcing fiber PA66.
[0048] The appearance of the waterproof capsule product in this embodiment is similar to that of a tire inner tube, which is a fully enclosed structure. It is inflated when in use, but the tire inner tube is a pure rubber product, and the waterproof capsule is a rubber / reinforcing layer / rubber composite product. The outer rubber layer is 13...

Abstract
The invention discloses a waterproof rubber bag and a manufacture method thereof. The waterproof rubber bag is of an annular structure, wherein an inflation connector is arranged; the waterproof rubber bag comprises an inner rubber layer, a reinforcing layer and an outer rubber layer; and the reinforcing layer is arranged between the inner rubber layer and the outer rubber layer. The manufacture method of the waterproof rubber bag comprises the steps of (1) bag blank preforming; and (2) vulcanization forming. The waterproof rubber bag is large in bearing air pressure and limitation air pressure and low in air leakage risk; the manufacture method is simple in technology; the waterproof rubber bag can be formed in one step; and the pressure bearing performance of the waterproof rubber bag is effectively improved.
Description
technical field [0001] The invention relates to an underwater water-stopping device and a manufacturing method thereof, in particular to a water-stopping capsule and a manufacturing method thereof. Background technique [0002] At present, many water projects need to be operated by prefabricated piers. Among them, the water stop between the underwater cap and the steel pipe pile is the key process for the installation of the prefabricated piers. The water stop method can be divided into rigid water stop and flexible water stop. Commonly used rigid water-stop materials include cement mortar, epoxy resin and other composite materials. Rigid water-stop technology is relatively mature, but the relative movement between the cap and the pile may easily cause cracks on the occlusal surface between the mortar and the steel pipe wall, and between the mortar and the cap wall. And the quality of underwater mortar is not easy to control. Flexible waterstops mostly use large deformation...
