How To Save Material In Geomembrane Engineering Of Welding Construction
The application of seepage-proof geomembrane is very extensive. In many construction projects, while the quality of construction is required, the control of construction funds is also included in a very important aspect. So how to ensure that materials are not wasted in the construction process of seepage-proof geomembrane?
Improper cutting of impervious high quality environmental geomembrane will seriously affect work efficiency and cause waste of impervious geomembrane. In fact, 20 m width is suitable for each piece of anti-seepage geomembrane after stitching. If it is too narrow, the number of times of laying and erecting anti-seepage geomembrane is too many, which causes waste and does not meet the requirements of funds control.
1. According to the circumference formula c=2 PIR divided by 2, the circumference of the round head is calculated, that is, the length of the outer edge of the anti-seepage geomembrane laying.
2. According to the cutting width of the anti-seepage geomembrane, the number of geomembrane laying edges are drawn along the outer edge of the laying with the circular gauge at the scale of 1:100. Then, according to the number of the bottom, the edge of the anti-seepage geomembrane laying edge is laid along the top.
3. Determine the width of each top width. But special attention should be paid to the same number of amplitudes at the bottom and at the top. In addition, it should be noted that when cutting, the width of suture must be 15 cm. The width of the suture on the most edge is 15 cm, and the width of the suture on both sides of the middle is 30 cm. In addition to the anchorage end, the remaining three sides reserve 10 cm wide splicing seam band for the splicing of membrane and membrane during construction. This will contribute to the full use of geomembrane materials, and will not lead to waste.
