What are the applications of cement blanket in canals

Concrete canvas is a kind of soft cloth impregnated with cement. It will react with water and harden into a very thin waterproof and fireproof durable concrete layer. It is a combination of traditional cement and textile fiber technology, in which anti-seepage and multi-functional concrete powder are integrated into the fiber skeleton. It has the characteristics of water-proof, moisture-proof, fire-proof and durable, and completely solves the problem of concrete cracking. It's only 15 kilograms per square meter. It's really light for traditional concrete. Most importantly, the high-quality cement blanket can not only save 90% of the material, but also shorten the construction period by 60%. Simply put, it is a fiber skeleton into the special concrete powder! At the same time, it makes this cement waterproof, moisture-proof, fireproof and durable! Before watering, it has the softness and toughness of textiles! After pouring water, it has the hardness and strength of concrete!

Today, Huai'an cement blanket manufacturer will introduce the problems of cement blanket laying construction.

Place and flatten the cement blanket joint at the overlap. 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

a. 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.

b. 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.

c. Apply sealant evenly at the joint.

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

⑤ Ditch edge treatment

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

⑥ Water curing

Before watering, it is necessary to check and accept the whole laying before watering. Watering can only be carried out after it is qualified! Water 9kg per square meter (the thickness is calculated as 10 mm) should be thoroughly watered, and no less water should be poured. Spray water evenly from the edge to the middle. The flow rate is 4000ml / min until the color of cement blanket becomes dark. Do not use high pressure water column! When the temperature is less than or equal to 5 ℃, insulation measures shall be taken; when the average temperature is higher than 30 ℃, the surface shall be covered with plastic film or geotextile and other materials to keep it moist, and the watering curing time shall not be less than 3 days. The PVC drain pipe of drainage hole shall be arranged in plum blossom shape of 2m × 2m, which shall not be omitted and installed firmly.

Inspection quantity: total inspection

Inspection method: observation and measurement with steel ruler.

The reserved size of the end face shall meet the requirements: 1-2m width of the slope length reserved on the top of the slope, and 50cm of the reserved length of the bottom surface.

Inspection quantity: total inspection

Method of measurement and inspection with steel ruler.
