Embodiment 1

[0041] At least 20 bundles of non-metallic fiber wires impregnated with resin glue are wound to form a ring rib (3) and a group of ring ribs (5) to form a fiber rib skeleton (4). Ring ribs (3) are arranged, and the intersections of the ring ribs (3) and group ring ribs (5) are bound with wire rods to form the fiber rib skeleton (4) of the gate. The concrete wraps the fiber reinforcement skeleton (4) as a whole to form a gate, and the fiber cloth layer (1) and anti-corrosion coating layer (6) are arranged on the surface of the concrete, such as figure 1 , figure 2 , image 3 , Figure 4 shown.

Embodiment 2

[0043] Annular rib (3) is oblong circular closed ring, and the two ends of annular rib (3) are U-shaped, and the both sides middle part of annular rib (3) is straight, as figure 1 shown.

Embodiment 3

[0045] The group ring ribs (5) are wrapped by multiple parallel windings of several ring ribs, the inner side of the middle part of the ring ribs of the outer ring is connected with the outer winding of the ring ribs of the adjacent inner ring, and the two ring ribs of the outer ring The end is longer than the adjacent inner ring ribs, and several outer ring ribs are continuously arranged to wrap adjacent annular ribs. The straight parts on both sides of the inner ring ribs are aligned with the adjacent outer ring ribs The straight parts on both sides of the middle part of the ring rib are wound and connected together to form a group ring rib (5) connected by group rings, such as figure 2 shown.

Abstract

A method for preparing water gate made of fiber concrete includes structuring fiber rib frame by ring form rib and group ring-rib wound up with twenty nonmetal fiber threads dipped in resin paste, setting group ring-rib in equal distance horizontally and setting ring form rib in equal distance longitudinally the applying wire to bind joint point of two said ribs for forming fiber rib frame of water gate, covering concrete completely on said frame for forming water gate then setting fiber cloth layer on concrete surface and coating anticorrosion layer on said cloth layer.

Description

technical field [0001] The invention relates to a hydraulic gate of a water conservancy project, in particular to a fiber-reinforced concrete hydraulic gate and a manufacturing method thereof. Background technique [0002] At present, there are more than 2,300 large and medium-sized sluices in my country, mainly metal steel structure gates, in addition, there are some wooden structure gates, and a small amount of steel mesh cement gates. Due to the change of water level, it is often in the environment of alternating wet and dry, and various chemical media in air or water are prone to electrochemical effects, and the rust and corrosion of the gate are very serious. In particular, metal hydraulic gates are generally prone to corrosion of steel materials, resulting in serious corrosion of metal hydraulic gates, short service life, and high maintenance and renewal costs for metal hydraulic gates. Subsequently, the safety and reliability of metal hydraulic gates are greatly redu...
