Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of drainage pipes, and particularly relates to a double-side glue injection embedded anti-cracking hollow wall winding reinforced plastic winding pipe. BACKGROUND
[0002] The winding pipe is generally formed by continuous winding, and has a hollow wall structure or a multi-layer structure. The hollow wall winding pipe has a hollow part in the middle, which can reduce the weight of the pipe material while ensuring a certain strength, and is convenient for transportation and construction. The multi-layer structure winding pipe is usually composed of layers with different materials or different properties. For example, the inner layer is a smooth polypropylene layer to ensure good water flow performance, and the outer layer is an anti-wear and anti-aging layer to improve the durability of the pipe material. The winding pipe is usually used as a drainage pipe and is applied to the fields of building drainage and municipal drainage.
[0003] The existing clamping embedded winding pipe is usually composed of a winding formed pipe body and a specially designed clamping structure. The pipe body is generally made by a continuous winding process and has a hollow wall structure or a multi-layer structure. The clamping structure is a special-shaped part, such as an annular clamping groove, a protrusion or a groove, which is arranged at the end or a specific position of the pipe material to realize the connection and sealing between the pipes.
[0004] However, the following problems still exist. The cooling formed mouth-shaped profile in the prior art relies on the molten filler during the winding process, and is bonded together circle by circle to form a pipe. Since the profile has been cooled, different crystallization states are generated with the filler, which makes it difficult to form a firm weld, and cracking is prone to occur during use. Content of the utility model

[0008] Preferably, the number of the pipe blank one is two, the two pipe blank ones are symmetrically arranged on the two sides of the pipe blank two with the vertical middle line of the side of the pipe blank two as the symmetric axis, the side of the pipe blank one close to the pipe blank two is provided with a side groove, the side groove is of the same shape and size as the glue injection groove one and the glue injection groove two, and the side groove corresponds to the glue injection groove one and the glue injection groove two respectively when the pipe blank one and the pipe blank two are wound, the side of the pipe blank one is provided with a single side groove, and the pipe blank one is located on the two sides of the plurality of pipe blank two, so that the side groove forms a cavity with the glue injection groove one and the glue injection groove two on the pipe blank two.
[0009] Preferably, the side groove, the glue injection groove one and the glue injection groove two form a cavity when the pipe blank one and the pipe blank two are wound, the glue injection groove one and the glue injection groove two are in the shape of a triangle, a thick cylinder, a semicircle and a barb, and the inner walls of the glue injection groove one and the glue injection groove two correspond to each other, the side groove, the glue injection groove one and the glue injection groove two are in the shape of a triangle, a thick cylinder, a semicircle and a barb and a missing-angle circle, and the cavity can increase the capacity of the sealing glue when buckling, and the connection between the pipe blank one and the pipe blank two and between the pipe blank two and the pipe blank two is enhanced.
