Abstract
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
The present invention relates to a kind of rubber dam bag and manufacturing technique method thereof of latitudinal lap-seam.
Background technology
The rubber dam accumbency is on the river course, and as the dam body broadwise, then the direction of road length is as dam body radially along the river with the river width direction.Existing rubber dam bag mostly adopts the radially production technology of whip stitch, and the cloth that is about to a width of cloth width of cloth length and is dam bag perimeter of section is along dam body broadwise overlap joint, finally overlaps out the rubber dam bag of the length that conforms to river width.The shortcoming of this production technology is:
1, the rubber dam bag overlapping the slot is many, the manufacturing process more complicated;
2, repeatedly block the cloth width of cloth, radially whip stitch increases waste of material and cost again;
3, on the anchor line of rubber dam bag, the rubber dam bag uneven thickness of the anchor line position of causing because of whip stitch radially easily causes the anchor line place seepage to occur;
4, the rubber dam bag surface irregularity of producing, the linearity of dam body on the river width direction that installation is come out is poor, and the globality of anti-upper water thrust is poor.
Summary of the invention
The rubber dam bag that the purpose of this invention is to provide a kind of latitudinal lap-seam, this rubber dam bag has reduced investment, processes easyly, can overcome the above-mentioned shortcoming of existing rubber dam bag.Another object of the present invention provides the production technology of this rubber dam bag latitudinal lap-seam.A kind of rubber dam bag of latitudinal lap-seam comprises the rubber dam bag that is formed by 1-100 width of cloth adhesive tape overlap joint, it is characterized in that whip stitch between each adhesive tape is in the broadwise of rubber dam bag.Latitudinal lap-seam comprises following processing step:
1, reduce: the adhesive tape that applies interior covering glue layer, outer covering glue layer and intermediate gelatine layer on the stress frame layer and vulcanizate is reduced according to the size of rubber dam length, and the width of adhesive tape is according to the fabric width of former cloth;
2, whip stitch:,, promptly make finished product with several width of cloth adhesive tape broad ways overlap joints according to the rubber dam bag perimeter of section.
The present invention has the following advantages compared with the prior art:
1, the rubber dam latitudinal lap-seam reduces whip stitch length in the whip stitch manufacturing process, reduces production costs, and shortens the production cycle;
2, the rubber dam latitudinal lap-seam can be eliminated the uneven thickness that the radial overlap of dam bag on anchor line causes, and no longer needs to level up the attached materials of installation such as sheet when therefore installing, and reduces installation cost, improves the reliability that antiseepage is installed;
3, the rubber dam latitudinal lap-seam can be avoided causing the ripple glaze in broadwise of dam body because of whip stitch radially, and the linearity of dam body length direction is poor, and the globality of anti-upper water thrust is poor.
Description of drawings
Accompanying drawing is the structural representation of the embodiment of the invention.
The specific embodiment
With the adhesive tape 2 that covering glue layer, outer covering glue layer and intermediate gelatine layer in applying on the stress frame material of 2 ~ 3 layers of polyamide fibre class are made, to reduce according to the broadwise length of the rubber dam 1 that will produce, the fabric width of adhesive tape 2 is not limit, generally according to the original fabric width of framework material; With adhesive tape 2 broad ways overlap joint, whip stitch 3 until the width that obtains rubber dam perimeter of section size, can obtain the rubber dam bag finished product in the broadwise of rubber dam.
Claims (2)
1, a kind of rubber dam bag of latitudinal lap-seam comprises the rubber dam bag (1) that is formed by 1-100 width of cloth adhesive tape (2) overlap joint, it is characterized in that whip stitch (3) between each adhesive tape (2) is in the broadwise of rubber dam bag (1)
2, the production technology of the rubber dam bag of a kind of latitudinal lap-seam according to claim 1 comprises the following steps: successively
A, reduction: adhesive tape is reduced according to the dam bag length.
B, whip stitch: with 1-100 width of cloth adhesive tape broad ways whip stitch, until the length that obtains the rubber dam bag perimeter of section.Can make finished product.
