Embodiment 1
[0032] Embodiment 1, the reinforcement of carbon fiber cloth 2+carbon fiber plate 3 specifically includes the following steps:
[0033] Step 1: First, use an angle grinder to smooth the inner wall of the pipe 1, then use oil-free compressed air to blow off the dust in the pipe 1; dry.
[0034] Step 2: Prepare the bottom glue, and then apply the bottom glue evenly on the inner wall of the pipe 1 with a roller brush or a brush, so that the thickness of the bottom glue meets the design requirements. When preparing the bottom glue, the main agent and curing agent of the bottom glue should be placed in a clean container according to the formula ratio specified for the bottom glue, and stirred evenly; at the same time, depending on the actual situation on site, ensure that the bottom glue is used up once within the applicable period.
[0035] Step 3: After the surface of the bottom layer is dry to the touch, if the surface of the bottom layer is flat, proceed to step 4; if the surf...
Embodiment 2
[0041] Embodiment two, two layers of carbon fiber cloth 2 reinforcement, then specifically include the following steps:
[0042] Step 1: First, use an angle grinder to smooth the inner wall of the pipe 1, then use oil-free compressed air to blow off the dust in the pipe 1; dry.
[0043] Step 2: Prepare the bottom glue, and then apply the bottom glue evenly on the inner wall of the pipe 1 with a roller brush or a brush, so that the thickness of the bottom glue meets the design requirements. When preparing the bottom glue, the main agent and curing agent of the bottom glue should be placed in a clean container according to the formula ratio specified for the bottom glue, and stirred evenly; at the same time, depending on the actual situation on site, ensure that the bottom glue is used up once within the applicable period.
[0044]Step 3: After the surface of the bottom layer is dry to the touch, if the surface of the bottom layer is flat, proceed to step 4; if the surface of t...
