Embodiment 1Pa

[0024] Embodiment 1Par class repair block

[0025] Figure 1A , 1B Shown is the bamboo composite pressure pipe whose gap matches the shape of the Par type repair block (the damaged part of the bamboo composite pressure pipe can be treated with a hole opener to form a qualified gap); Figure 1C The Par patch is shown, which is a curved ellipse, with the major axis of the ellipse on a straight line and the minor axis on the curved surface.

[0026] The outer surface of the repair block consists of a protruding ellipse (i.e. a protruding arc surface, at this time the outline of the repair block is elliptical), a concave ellipse (i.e. a concave arc surface, at this time the outline of the repair block is elliptical) and the side curved surface, wherein, the protruding ellipse and the concave ellipse are respectively located on two coaxial cylindrical surfaces (corresponding to the outer surface and the inner surface of the bamboo composite pressure pipe respectively), and the pro...

Embodiment 2

[0027] Embodiment 2Per class repair block

[0028] Figure 2A ,2B Shown is a bamboo composite pressure pipe whose gap matches the shape of the Per repair block (a hole opener can be used to treat the damaged part of the bamboo composite pressure pipe to form a qualified gap); Figure 2C Shown is a Per-type repair block, which is a curved ellipse, with the short axis of the ellipse on a straight line and the long axis on the curved surface.

[0029] The outer surface of the repair block is composed of a convex ellipse, a concave ellipse and a side curved surface, wherein the convex ellipse and the concave ellipse are respectively located on two coaxial cylindrical surfaces (respectively combined with bamboo composite pressure The outer surface of the tube corresponds to the inner surface), the ellipse center of the protruding ellipse, the ellipse center of the concave ellipse and the axis of the cylindrical surface are located in the same plane; any point on the edge of the pr...

Embodiment 3

[0036] The repair of embodiment 3 bamboo composite pressure pipes

[0037] The bamboo composite pressure pipe with a nominal pipe diameter of 150 mm was repaired with the modified block in Example 1 (long axis 2a of the ellipse=120 mm).

[0038] First, process the damaged part of the bamboo composite pressure pipe to be repaired with a hole opener to form a gap matching the shape of the repair block; then, apply glue on the side surface of the repair block (the glue is preferably the bamboo Composite pressure pipe structure layer used resin), then put the repair block into the gap of the bamboo composite pressure pipe (make the protruding oval surface of the repair block fit with the outer surface of the bamboo composite pressure pipe to form a complete the cylindrical surface; make the concave elliptical surface of the repair block fit with the inner surface of the bamboo composite pressure pipe to form a complete cylindrical surface), after curing (according to the differenc...

Abstract

The invention discloses a repairing block special for a bamboo compound pressure product and a damage repairing method for the repairing block. The repairing block is in an arc-shaped plate shape, and the outline of the repairing block is round or ellipsoidal; the outside surface of the repairing block is composed of a convex arc face, a concave arc face opposite to the convex arc face and a lateral hook face around the position between the convex arc face and the concave arc face in the circumferential direction; the convex arc face and the concave arc face are located on two coaxial cylindrical faces respectively; and the thickness of the repairing block is the same as the wall thickness of the bamboo compound pressure product. The key shape and structure of the repairing block, the key connecting fixing mode in the repairing method and the like are improved, and compared with the prior art, the problem that the mechanical property of the repaired bamboo compound pressure pipe is reduced is effectively solved; and in addition, according to the repairing method, as conditions in the repairing operation process are controlled, the repaired bamboo compound pressure pipe can achieve application the same as that of an original complete bamboo compound pressure pipe.

Description

technical field [0001] The invention belongs to the technical field of bamboo composite pressure products, and more specifically relates to a special repair block for bamboo composite pressure products and a damage repair method thereof. Background technique [0002] Bamboo composite pressure products are cylindrical products made of green and environmentally friendly bamboo materials with winding technology, such as bamboo winding composite pressure pipes, bamboo winding storage tanks, bamboo winding poles, bamboo winding silos, etc. During the use of bamboo composite pressure products, the wall of the cylinder may be damaged due to environmental and human factors, which greatly reduces the use function. In the prior art, when the bamboo composite pressure product is damaged, the damaged area is often cut off or the damaged product is discarded directly, which is a waste of resources. Repairing can also be used, but at present the repairing work often relies on manual oper...
