Problems solved by technology
[0003] 1. There are many lap seams in the rubber dam bag, and the production process is more complicated;
[0004] 2. Cutting off the cloth width many times, and then seaming radially will waste materials and increase costs;
[0005] 3. On the anchoring line of the rubber dam bag, the thickness of the rubber dam bag at the anchoring line position caused by the radial seam is uneven, which may easily cause leakage at the anchoring line;
[0006] 4. The surface of the produced rubber dam bag is uneven, and the straightness of the installed dam body in the width direction of the river channel is poor, and the integrity of resisting upstream water thrust is poor

Embodiment Construction
[0015] The adhesive tape 2 made by coating the inner covering rubber layer, the outer covering rubber layer and the intermediate adhesive layer on the stressed skeleton material of 2~3 layers of nylon is cut according to the latitudinal length of the rubber dam 1 to be produced, and the length of the adhesive tape 2 is The width is not limited, generally according to the original width of the skeleton material; the tape 2 is lapped along the width direction, and the seam 3 is in the latitudinal direction of the rubber dam, until the width of the perimeter dimension of the rubber dam section is obtained, and the rubber dam can be obtained Bag finished.

The invention relates to a latitudinal lap-seam rubber dam bag and a production technology method thereof. The latitudinal lap-seam rubber dam bag comprises a rubber dam bag and is characterized in that the lap seam of the rubber dam bag is arranged in the latitudinal direction of the rubber dam bag. The production technology comprises the cutting step according to the length of the rubber dam bag and the latitudinal lap-seam step according to the cross section circumference of the rubber dam bag. The invention can reduce the length of the lap seam in the lap-seam production process of the rubber dam bag, decrease the production cost and the installation cost, shorten the production period, improve the installation anti-seepage reliability, improve the linearity of a bam body in the length direction and improve the integrity for resisting the pushing force of upstream water.
Description
technical field [0001] The invention relates to a rubber dam bag seamed in a weft direction and a production process thereof. Background technique [0002] The rubber dam lies on the river channel, the width direction of the river channel is regarded as the latitudinal direction of the dam body, and the direction along the length of the river channel is regarded as the radial direction of the dam body. Most of the existing rubber dam bags adopt the production process of radial seaming, that is, a piece of cloth whose length is the circumference of the section of the dam bag is lapped along the latitudinal direction of the dam body, and finally a rubber dam bag with a length matching the width of the river channel is lapped. The disadvantages of this production process are: [0003] 1. There are many lap seams in the rubber dam bag, and the production process is more complicated; [0004] 2. Cutting off the cloth width many times, and then seaming radially will waste materi...
