Problems solved by technology

[0002] At present, the production and installation method of the straight wall slope dam is based on the length of the foundation plus the height of the wall. After the dam bag is produced, it is anchored from the straight wall on one side to the straight wall on the other side. The production and installation of the dam bag The problem in the installation form is that the dam bag is seriously discounted at the transition position between the straight line section and the straight wall. This part is prone to stress concentration points of the dam bag, which will cause the dam bag to be easily aged and damaged, and the service life will be affected. At the same time, the dam bag will be discounted after being filled. The phenomenon obviously leads to the unattractive shape of the dam and poor water retaining effect at the discounted position

Embodiment 1

[0031] The cord fabric rubber dam bag of this embodiment is suitable for water-filled rubber dams. The dam height is 1.5m, the dam bottom length is 16.9m, the internal pressure ratio is 1.25, and the slope ratio is 1:0.5. The size of the dam bag in this embodiment is: 6.084m×21.3m, dam bag thickness is 10mm; among them, according to the dam bag size 6.084m×21.3m, width plus 1%-2% shrinkage, length plus 5%-10% shrinkage, the design size is: 6.2m×22.3m.

[0032] The cord fabric rubber dam bag includes a dam bag body 1, and the inside of the dam bag body 1 is provided with a multi-layer skeleton layer 7, and each skeleton layer 7 is composed of a plurality of cords 2 spaced apart and arranged obliquely. The cords 2 of the adjacent skeleton layers are symmetrical in slanting directions. The dam bag body 1 and the skeleton layer are combined into one body through a vulcanization process. Both sides of the dam bag body 1 are provided with side glue 3, and the dam bag body 1 and the sid...

Embodiment 2

[0047] The cord fabric rubber dam bag of this embodiment includes a dam bag body 1, and the inside of the dam bag body 1 is provided with a multi-layer skeleton layer 7, and each layer of skeleton layer 7 is composed of a plurality of spaced and inclined curtains. The cord 2 of the adjacent skeleton layer is symmetrical in the direction of the cord 2, the dam bag body 1 and the skeleton layer are combined into one body through a vulcanization process. Both sides of the dam bag body 1 are provided with side glue 3, and the dam bag bag A reinforcing layer 4 is provided between the body 1 and the side glue 3 to combine the two into one body; the inclination angle of the cord 2 is 45 degrees;

[0048] The processing technology of the cord cloth rubber dam bag of this embodiment includes the following processing steps:

[0049] 1). Lay a plurality of cords 2 at intervals and obliquely on the bottom rubber surface 5. After laying the first layer, lay the second layer in a direction symme...

Abstract

The invention belongs to a rubber dam bag and a processing technique thereof, in particular to a cord fabric rubber dam bag and a processing technique thereof. The cord fabric rubber dam bag comprises a bag body; multiple frame layers are arranged within the bag body; each frame layer is composed of a plurality of cords obliquely arranged at intervals; the cords of every two frame layers incline in symmetric directions; the bag body is integrally combined with the frame layers by the vulcanizing process. The cord fabric dam bag is long in service life and good in flexibility; the strength of the frame layers can be decreased; the problem that the linear segment of the bag and a straight wall fold is solved; anchoring the bag to the straight wall is not required during mounting; airtightness is improved, and waterproofing effect is improved.

Description

Technical field [0001] The invention belongs to a rubber dam bag and its processing technology, in particular to a cord cloth rubber dam bag and its processing technology. Background technique [0002] At present, the production and installation method of straight-wall slope dams is based on the foundation length plus the wall height. After the production of the dam bag is completed, anchor the dam bag from one straight wall to the other straight wall. The problem of the installation form is that the dam bag is seriously discounted at the transition position between the straight section and the straight wall, and the stress concentration point of the dam bag is prone to appear in this position, which causes the dam bag to be easily aging and damaged, and its service life is affected. Obviously, the dam shape is not beautiful enough and the water retaining effect of the discount position is poor. Summary of the invention [0003] The purpose of the present invention is to solve ...
