The construction and maintenance of cast basalt pipe are introduced

Construction technology of cast basalt pipe

1. Inspect the shell before construction and clean up sundries and oil stains.

2. Apply epoxy slurry and sprinkle a small amount of quartz sand after brushing to increase adhesion.

3. The bonding surface of the used cast basalt slab shall be kept clean, and the sundries shall be wiped off to stick firmly.

4. The bonding method of cast basalt slab shall be kneading and squeezing method, and the mastic shall be full.

5. During the lining of cast basalt slab, the thickness of the bonding layer is generally 1-1.5cm and the width of the mud joint is 3-8mm. The higher points at the four corners shall be knocked with a rubber hammer to ensure the flatness. The mortar knocked out shall be scraped with an putty knife.

6. Workers shall wear rubber gloves during construction. During the installation and construction of cast basalt chute, masonry shall be carried out from low to high. There shall be no deficit at the joint between plates. First stick the bottom plate and then lay plates on both sides.

Construction maintenance

After construction, it can be put into use after 15 days of natural curing.
