Method for Saving Construction Cost when Laying Anti-seepage Film
Those who have experience in construction of impermeable membranes know that reasonable application can save a lot of costs when laying, so when laying impermeable membranes produced by aquaculture geomembrane manufacturers, we are required to lay them according to certain principles. How should the cost of construction be laid?
The cutting of the round head part first calculates the half-circle length of the round head according to the circumferential formula c = 2πr divided by 2. Lay the line along the top impermeable membrane to determine the width of each top. In addition, it is necessary to pay attention to the 15cm suture width when cutting. If it is too narrow, the number of laps of the impermeable membrane will cause waste, and it does not meet the requirements for funding control.
The length of the outer line is laid according to the cutting width of the impermeable membrane, except for the anchoring end, the remaining three sides are reserved with 10cm wide splicing seam tape, and the outer line is laid along the scale of 1: 100 with a compass. The width of the bottom and the width of the top must be the same. After each impermeable membrane is sutured, it is more suitable to be 20m wide. The one on the side is left with a width of 15cm, and the middle is left with a width of 30cm.
Improper cutting during the use of the impermeable membrane will seriously affect the work efficiency and cause waste of the impervious membrane. In order to prevent unnecessary waste when using the impermeable construction of geomembrane on top of slag yard, we should lay the impermeable membrane according to the above standards.
We also need to consider the deviation of products when producing geotextiles. Generally speaking, the standard deviation of geotextiles includes two types of geotextile mass deviation and width deviation, then how is the standard deviation of geotextiles carried out? Calculated?
Determination method of mass deviation per unit area: randomly sample 6 to 10 pieces of geotextiles of the same batch in the same batch for weighing, and the average of the actual weights is the actual mass per unit area of the batch of products. Mass minus the mass per unit area, and using this value to remove the mass per unit area is the mass deviation per unit area.
The measurement method of width deviation is almost the same as that of quality deviation: in the same batch of products of the same specification, draw 6 to 10 volumes of soil for corresponding measurement, and the measured width is added to the average to get the actual width, the actual The width obtained by subtracting the specified width and divided by the specified width is the deviation of the width.
