What should be paid attention to when laying cement blanket?

Date of release:2020-02-19 Author: Click:

Although the cement blanket products are easy to use, there are still some problems that need to be paid attention to during the construction. Today, the cement blanket manufacturer will introduce the problems that should be paid attention to in the construction of cement blanket!

Cement blanket products

1、 Preparatory work

First of all, planning and measurement should be carried out to ensure a certain slope, so that the water can flow smoothly from the upper end to the lower end; second, after the construction site is cleaned and leveled, the construction line is set according to the design drawing, and the drainage slope is retested.

2、 Excavation

The construction line shall be set up according to the design requirements, both sides of the ditch shall be leveled, and there shall be no empty soil and cavity on the slope surface of the ditch. To tamp the water damaged parts, in addition to the debris and gravel in the slope, if necessary, use Panax notoginseng lime soil compaction treatment, or grouting reinforcement after sealing, which requires that the treated parts have good stability!

3、 Laying

The material can be laid vertically and horizontally. Please make sure that the base is smooth, otherwise it will affect the appearance quality!

4、 Joint treatment

① A pit with a width of 10 cm and a depth of one time of the cement blanket shall be excavated horizontally at the overlapped position of two adjacent cement blankets, and the joint of cement blanket at the overlapping place shall be put into place and flattened.

② Press the upper cement blanket on the lower cement blanket along the water flow direction, and the overlapping position shall not be less than 10cm.

③ Apply sealant evenly at the joint.

④ Fix two pieces of cement blanket with Φ 5 * 38mm stainless steel screws.

⑤ The edge of the material is fixed on the edge of the trench with rivets, and the overlapped part is also fixed with rivets. After fixing, the edge can be covered with soil

⑥ Before watering and solidifying, it is necessary to check and accept the whole laying before watering. Watering can be carried out only after it is qualified! Water 9kg per square meter (the thickness is calculated as 10 mm) should be thoroughly watered, and no less watering is allowed. Water should be evenly sprinkled from the edge to the middle. The best way is to spray the water with the flow rate of 4000ml / min until the color of the cement blanket becomes dark. Do not use high pressure water column! When the temperature is less than or equal to 5 ℃, insulation measures should be taken; when the average temperature of day and night is higher than 30 ℃, the surface should be covered with plastic film or geotextile and other materials to keep moist, and the watering curing time should not be less than 3 days
