Example Embodiment
[0044] Example one.
[0045] Such as figure 1 Shown.
[0046] A composite material bridge pier reinforcement method, which includes the following steps:
[0047] (1) The fiber material is three-dimensionally knitted into a round or rounded rectangular sleeve with a height of not less than 10 cm (preferably 10-50 cm) with an opening. The inner wall of the sleeve is a ring-shaped reinforcing rib 9, which can be It can be arranged longitudinally or horizontally along the inner wall, and can also be arranged irregularly. The height and spacing of the reinforcing ribs can be designed according to the stress situation to maximize the actual requirements.
[0048] (2) Sleeve the composite material sleeve as a permanent template on the surface of the bridge pier, pour concrete (preferably epoxy mortar) between the sleeve and the outer wall of the existing bridge pier, so that the sleeve and the pier are connected as a whole, and the sleeve is strengthened Ribs can greatly improve the adhesio...
Example Embodiment
[0054] Example two.
[0055] Such as Figure 2-6 , As shown in 12.
[0056] A bridge pier reinforcement device, which includes a plurality of circular hoop type composite material sleeves 2 (such as figure 2 ), the composite material can be a single glass fiber, carbon fiber, basalt fiber, aramid fiber, etc., or a hybrid woven of the above fibers. Different angles and colors can be used when weaving. The sleeve 2 is sleeved on the pier 1, and an epoxy mortar protective layer 10 is cast between the pier 1 and the sleeve 2 ( figure 1 b) The composite material sleeve 2 is woven by a three-dimensional weaving process, and it has an opening 3 that is convenient to fit on the pier (such as image 3 ), the opening 3 of each sleeve 2 should be provided with lap edges ( figure 1 b) The width of the overlapping edges is about 5 cm. The overlapping edges can be connected by bonding so that the sleeve forms an integral annular structure. The inner wall of each sleeve 2 is provided with a conv...
Example Embodiment
[0062] Example three.
[0063] Such as Figure 7-12 Shown.
[0064] A bridge pier reinforcement device, which includes a plurality of rectangular hoop-type composite material sleeves 5 (such as Figure 7 ), the composite material can be a single glass fiber, carbon fiber, basalt fiber, aramid fiber, etc., or a hybrid woven of the above fibers. Different angles and colors can be used when weaving. The sleeve 5 is sleeved on the rectangular pier 4 ( Picture 8 ), an epoxy mortar protective layer 10 is cast between the pier 4 and the sleeve 5 ( figure 1 a. Picture 8 ), the composite material sleeve 5 is woven by a three-dimensional weaving process, and it has an opening 6 (such as Figure 7 , 8 ), the opening 6 of each sleeve 5 should be provided with lap edges ( figure 1 a, 8) The width of the overlapping edges is about 5 cm. The overlapping edges can be connected by bonding so that the sleeves form an integral ring structure. The inner wall of each sleeve 5 is provided with a rais...
