Description

Technical Field

[0001] The utility model relates to a rubber dam body with buttonhole type anchor holes and a rubber air bag of a buttonhole type anchor hole air shield dam, belonging to the technical field of water-blocking water conservancy facilities. Background Art

[0002] Dams are important facilities of modern water conservancy, which play an important role and benefit the national economy and people's livelihood. From earth dams, concrete dams, steel dams (gates) to today's movable dams, rubber dams and air shield dams.

[0003] The rubber airbag, the key core component of the rubber dam and air shield dam, is a large rubber composite product made of high-strength fiber as the load-bearing skeleton and processed into a multi-layer skeleton. The rubber dam and rubber airbag are firmly fixed to the concrete foundation of the dam bottom by anchor bolts, and then the air (water) is filled through the pipe to complete the lifting and lowering of the dam body to control the water retaining.

[0004] At present, the anchoring method for most rubber dams and air shield dam rubber airbags is: directly punch holes on the vulcanized finished products, then pass the anchor bolts through the eyelet anchor holes on the rubber dams and air shield dam rubber airbags, and then press and seal them through upper and lower pressure plates.

[0005] Punching holes in rubber dams and rubber airbags of air shield dams will break the fibers of the internal skeleton layer, causing loss of their strength. Engineering accidents of tearing rubber dams and rubber airbags of air shield dams often occur, causing harm to people's lives and property.

[0006] In order to solve the above problems, CN105178247 B discloses "a dam bag and airbag for a water retaining dam and a production method thereof", comprising a dam bag body (1), wherein a plurality of skeleton layers (2) are arranged inside the dam bag body (1), wherein each skeleton layer (2) is composed of a plurality of spaced and inclined cords (3), wherein the cords (3) of adjacent skeleton layers are inclined in symmetrical directions, wherein the dam bag body (1) and the skeleton layer (2) are integrated into one body through a vulcanization process, wherein an upper rubber surface (4) is arranged above the skeleton layer (2), and a lower rubber surface (5) is arranged below the skeleton layer (2), and a hole (6) penetrating the bag body is provided on the dam bag body; in the process of forming the hole penetrating the bag body, a "placeholder column" must be preset, and in each step of laying the surface rubber, each skeleton layer and the inner rubber, the "placeholder column" must be carefully bypassed, and the process is relatively complicated, inefficient and has a high manufacturing cost; the hole formed on the body can be regarded as a "defect" and still causes the rubber dam and the rubber airbag to be torn.

[0007] CN 209178937 U discloses “an airbag for an air shield dam with a reserved hole”, comprising an airbag bag (1), characterized in that one end of the airbag bag (1) is provided with an airbag extension part (2) which is integrated with the airbag bag (1) and used for fixing to the dam surface, the airbag extension part (2) is provided with a frame inside, the frame is a mesh frame formed by crossing multiple layers of horizontal cord wire nets (201) and multiple layers of vertical cord wire nets (204), and the mesh frame and the airbag extension part (2) are vulcanized into an integrated structure; the airbag extension part (2) is provided with an extension layer (201) parallel to the upper surface of the airbag extension part (2) inside 202), the extension layer (202) and the airbag extension part (2) are vulcanized into one, a plurality of fixing holes (203) penetrating the airbag extension part (2) are reserved on the airbag extension part (2), and the cords in the horizontal cord network (201) bypass the fixing holes (203) and are cross-arranged; a connecting sleeve (205) is embedded in the fixing hole (203), the outer wall of the connecting sleeve (205) and the inner wall of the fixing hole (203) are vulcanized into one, and the cords in the horizontal cord network (201) bypass the connecting sleeve (205) and are cross-arranged to form a water The flat mesh structure; the extension layer (202) is made of an extension steel plate, and the connecting sleeve (205) passes through the extension layer (202) made of the extension steel plate and is fixedly connected to the extension layer (202) made of the extension steel plate; the connecting sleeve (205) and the extension layer (202) are fixedly connected by welding; the connecting sleeve (205) is used to make the fixing hole (203) more conducive to dispersing the pulling force, but the preforming process steps of the main body are complicated. When laying each functional layer, it is necessary not only to carefully bypass the connecting sleeve (205), but also to avoid the extension steel plate, and during the integral vulcanization, the vertical The pressure on the airbag surface will cause the extended steel plate parallel to the airbag surface to deform and pull apart its welded connection with the connecting sleeve (205). Furthermore, during the simultaneous integrated vulcanization, the airbag extension part (2) has an extended steel plate (rigidity) and the airbag body (elasticity) made of homogeneous rubber material, and the two parallel hot plates of the flat vulcanizer are subjected to uneven force, resulting in different vulcanization effects of the airbag extension part (2) and the airbag body, generating internal stress, affecting the performance and quality of the airbag, and further causing the two parallel hot plates of the flat vulcanizer to deform and damage the processing equipment. This method has complicated process steps and requires manual operation, low efficiency and high manufacturing cost. Utility Model Content
