Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of corrosion-resistant trench channel, in particular to a construction process of high-strength corrosion-resistant glass steel trench channel. BACKGROUND

[0002] The traditional anti-corrosion trench channel is often discharged with Na2SO4.10H2O liquid (temperature about 75~95℃) into the trench, and the trench is seriously corroded in less than one year after production, most of the original anti-corrosion layer cracks and falls off, causing the trench concrete matrix to be damaged.

[0003] 1. The original anti-corrosion layer of the trench and the corrosion phenomenon The original anti-corrosion layer of the trench: 30mm thick granite surface layer epoxy mortar joint, asphalt mortar combined layer, three cloth four oil "Jianbitel" isolation layer, concrete base.

[0004] The corrosion damage observed before the trench reconstruction: the joint of the granite plate has cracked and most of it has fallen off. The asphalt mortar of the combined layer has become a flowing state and some parts have aged and cracked. The "Jianbitel" isolation layer has also fallen off, and the exposed concrete is loose and deep to 3~5mm. The long-term use temperature of asphalt materials is below 70℃, while the temperature of NazS04·10H20 liquid is 75~95℃ and the viscosity is large, which is not suitable for heat dissipation. Under the repeated immersion of NazS0:10H20, the asphalt softens and flows, losing the bonding strength to the granite plate, which eventually leads to the plate falling off and exposing the concrete base, resulting in the corrosion and damage of the concrete.

[0005] Corrosion mechanism of NaSO:10H0 on concrete Concrete is a porous material, and NaS0·10H0 solution can easily penetrate into it and react inside due to the dry and wet environment as follows:

[0006] And the molecular volume of Na2SO4.10H20 is much larger than that of NaSO, which causes the concrete to be loose and lose strength.

[0007] In summary, to prevent the corrosion of Na2SO4.10H20 on concrete, the main point is to choose an anti-corrosion layer that can resist its penetration and temperature.

[0008] Therefore, a construction process of high-strength corrosion-resistant glass steel trench channel is needed. SUMMARY

[0022] Tool preparation: Prepare the tools required for construction, such as electric drill, wrench, screwdriver, level, steel tape, sealant gun, cutting machine (for glass steel sink size adjustment), etc., and ensure that the tools are in good condition and can be used normally.

[0023] Material transportation and storage: Transport the glass steel sink and other materials to the construction site, pay attention to protect the glass steel sink during transportation to avoid collision and scratching.
