CASE STUDY

  • Location – Kenya
  • Product(s) –  Large Pond Lines for Sale
  • Application – Dam Project

Issue

The dam slope is a rockfill slope. The upstream of the rockfill dam is paved with stones, which can effectively prevent the damage of upstream sediment to the dam, and the surface is troweled with simple cement. Then the customer in Kenya decided to lay HDPE high-density ethylene film on it.

Solution

Large pond lines for sale are the kind of impervious geosynthetics, which are widely used for landfill, dam, aquaculture, industrial engineering, energy engineering, mining engineering projects and so on. Large pond lines for sale have the characteristics of excellent anti-seepage performance, good chemical corrosion resistance, excellent stress cracking ability, low permeability, good UV resistance and low-temperature brittleness.

In this regard, BPM engineers used HDP geomembrane slope protection and reinforcement technology. The application principle of HDPE geomembrane slope protection and reinforcement technology in complex broken open-air slope is as follows: the anti-seepage membrane can prevent rainwater from entering the soil, prevent loose soil from affecting the strength and stability of the soil under the action of rainwater, and prevent the overall sliding caused by the reduction of mechanical parameters of sliding surface or the increase of self weight. By applying HDPE impervious membrane slope protection and reinforcement technology to the complex broken open-air slope, even if a large range of through cracks appear on the slope under the action of rain, the problem of slope sliding can be prevented.

Benefits

High density polyethylene (HDPE) large pond lines for sale has good stability, interface friction coefficient and inherent flexibility. The application of full reservoir plate waterproof in hydraulic engineering can not only make up for the deficiencies in hydraulic engineering in time, but also provide a safety guarantee for people’s life. According to the above analysis of the overall anti-seepage technology, there are many reasons for the defects of geomembrane anti-seepage technology, but in the final analysis, it is because the current technical level is not perfect, as well as the unscientific application and unprofessional personnel and other factors that the whole reservoir anti-seepage technology of geomembrane pond liner can not be well implemented. We should also avoid the quality problems caused by improper operation in the anti-seepage construction of water conservancy projects. In the specific practical application, we should select reasonable anti-seepage technology according to different geological conditions, achieve the perfect integration of materials and technology, give full play to the maximum potential of geomembrane anti-seepage technology, and make sufficient preparations for the smooth progress of water conservancy projects.

Construction method of HDPE Geomembrane Pond Liner

Before applying impermeable large pond lines for sale, the slope surface should be leveled to prevent sharp outburst, and then the loose soil should be covered with impermeable membrane.

1) It should be extended from the bottom to the high position, not too tight, and 1.50% margin should be reserved for local sinking and stretching. Considering the actual situation of the project, the slope is laid from top to bottom.

2) The two adjacent longitudinal joints shall not be in a horizontal line, and shall be staggered by more than 1m.

3) The longitudinal joint shall be more than 1.50M away from the dam foot and bending foot, and shall be set on the plane.

4) Slope first and then bottom.

5) When the slope is laid, the film spreading direction should be basically parallel to the maximum slope line.

Slope laying: before laying the anti-seepage geomembrane on the slope, the laying area shall be inspected and measured. According to the measured size, the anti-seepage geomembrane with matching size in the warehouse shall be transported to the anchorage ditch platform of phase I. during laying, the convenient way of “pushing” from top to bottom shall be adopted according to the actual site conditions. In the sector area, it should be cut reasonably to make the upper and lower ends firmly anchored.

Site bottom laying: before laying the anti-seepage geomembrane, the laying area shall be inspected and measured, and the anti-seepage membrane matched with the size in the warehouse shall be transported to the corresponding position according to the measured size. During laying, the anti-seepage membrane shall be pushed manually in a certain direction.

Alignment and alignment：The paving of BPM HDPE textured geomembrane, no matter the side slope or the bottom of the field, should be flat and straight to avoid wrinkles and ripples, so as to make the two geomembranes aligned and aligned. According to the design requirements, the lap width is generally about 10 cm.

Pressing: press the aligned and aligned BPM HDPE textured geomembrane with sand bags in time to prevent the wind from blowing and pulling. Laying in Anchorage ditch: at the top of anchorage ditch, a certain amount of impervious membrane shall be reserved according to the design requirements for local sinking and stretching.

Longitudinal joint: the uphill section is on the upper side and the downhill section is on the lower side, and sufficient lap length ≥ 15cm shall be reserved. The bentonite pad shall be laid in the area after passing the acceptance, and the manual “push paving” shall be carried out in a certain direction.
