Abstract
The utility model relates to a book spine strong rubber dam, which is an improved structure for rubber dam and a new rubber product for hydraulic architecture, and comprises a book spine 1 with a top, an inner rubber liner 2 on the inner side, an intermediate rubber liner 3 in the middle, a cloth layer 4, an outer rubber liner 5 on the outer side and a side rubber liner 6 at the bottom. The utility model is characterized in that a metal reinforcing layer 7 is arranged between the intermediate rubber liner 3 and the cloth layer 4. The utility model has the advantages that the transverse rigidity, overall tearing resistance, bending resistance and puncture resistance are enhanced, and the book spine rubber dam can completely fit on the ground, mitigate the problem that the tobacco-pipe-shaped water collecting zone is present downstream of the dam sack, thus improving the overall performance of the book spine strong rubber dam and saving the cost, and fast effectiveness is available and the dam can be widely used in small hydropower projects.
Description
(1) technical field
The utility model relates to a kind of improvement of rubber dam structure, belongs to the hydraulic architecture product, is the powerful rubber dam of a kind of spine formula specifically.
(2) background technology
Rubber dam is a kind of novel hydraulic architecture product, can either satisfy the flood control requirement, saves 1/3rd to 2/3rds investment again than other type dam, and instant effect.Chemical ﹠ blended fabrics such as the inner general usefulness polyamide fibre canvas of existing rubber dam are as skeleton, and the major defect of existence is that lateral stiffness is relatively poor, thereby the whole impact resistance of rubber dam is poor.When running into powerful the impact, can produce certain amount of deflection, also rubber dam may be drawn and split; Existing rubber dam majority has whip stitch to connect, and the whip stitch place is infiltration and ventilative easily, increases maintenance cost, influences the performance of rubber dam allomeric function.
(3) summary of the invention
The utility model purpose is to overcome the shortcoming in the above-mentioned technology, proposes the powerful rubber dam of a kind of spine formula, makes it can increase lateral stiffness, makes its integral body tear-resistant.
The utility model purpose is realized by following technical scheme: the powerful rubber dam of this spine formula, include the spine 1 at top, inboard inner glue layer 2, the mesoglea 3 and the layer of cloth 4 at middle part, the outer glue-line 5 in the outside, the limit glue-line 6 of bottom is characterized in that accompanying layer of metal enhancement Layer 7 between mesoglea 3 and layer of cloth 4.
The metal shielding 7 of the powerful rubber dam of spine formula is the layer of steel wire cord.
Wirecord fabric is horizontal evenly distributed steel wire, and steel wire diameter is the 0.5-0.7 millimeter, and the steel wire spacing is the 3-7 millimeter.The steel wire spacing is determined according to the requirement of the concrete condition of work of rubber dam.
Each root steel wire is twisted with the fingers by 2-5 thigh all-steel cord 71, and the diameter of all-steel cord is the 0.3-0.4 millimeter, and the lay pitch is the 15-17 millimeter, twists with the fingers to twisting with the fingers for S or the Z sth. made by twisting.Because the diameter of steel wire strand cord is littler, increased with the contact area of sizing material, increased the bond strength of all-steel cord and sizing material, the application life of prolongation rubber dam.
The utility model advantage is: owing to accompany layer of metal enhancement Layer 7 between mesoglea 3 and layer of cloth 4, it is horizontal evenly distributed steel wire, lateral stiffness, whole tear-resistant ability and the anti-ability of subduing of the powerful rubber dam of spine formula have been increased, increased the anti-ability of exposing, the spine rubber dam can fall flat fully, the problem in tobacco pipe shape water district appears in the downstream that can also alleviate the dam bag, has improved the overall performance of the powerful rubber dam of spine formula; And can realize not having whip stitch and connect; Producing the utility model product does not need special installation, all can produce in general conveyer belt Production Regional, saves investment, and instant effect can be widely used in small hydraulic project.
(4) description of drawings
Fig. 1 is the cross-section structure of the powerful rubber dam of a kind of spine formula,
Fig. 2 is an all-steel cord end face partial enlarged drawing,
Fig. 3 is an all-steel cord braiding structure schematic diagram.
(5) specific embodiment
Embodiment of accompanying drawings.Fig. 1 is the cross-section structure of the powerful rubber dam of a kind of spine formula.Model is 2500 * (3+1) * (6+3) 100 meters.The powerful rubber dam of this spine formula, integral width is 2500 millimeters, (3+1) expression layer of cloth 4 by three layers of canvas forms with the layer of steel wire cord as metal shielding 7; (6+3) the outer glue-line 5 of expression is 6 millimeters with General Logistics Department's degree of mesoglea 3, and the thickness of inner glue layer 2 is 3 millimeters; 100 meters expression length are 100 meters.The top is a spine 1, and the bottom is a limit glue-line 6.Metal shielding 7 is layer of steel wire cords.Wirecord fabric is horizontal evenly distributed steel wire, and each root steel wire is that 0.32 millimeter all-steel cord 71 is twisted with the fingers by 3 diameters, and the lay pitch is 16 millimeters, twists with the fingers to S and twists with the fingers, and the diameter after the braiding is 0.7 millimeter.Represent by Fig. 2, Fig. 3.
During production, to begin moulding after the requirement calendering in accordance with regulations of canvas, wirecord fabric and film, during moulding, earlier canvas is fit together, paste inner glue layer again, then along the center to the doubling of inner glue layer direction, the middle part pad is with separation layer, spread wirecord fabric and mesoglea, outer glue-line in the canvas outside, again spine partly can be vulcanized with the sizing material polishing.The gross thickness of cure time after according to moulding calculates.
Claims (4)
