Abstract
The utility model discloses a reinforced spiral corrugated pipe which comprises a pipe body formed by spirally winding and bonding strip-shaped plates, wherein each strip-shaped plate comprises a base plate and three closed cavities arranged at the left, middle and right parts of the base plate, reinforcing ribs are arranged in the closed cavities, and a reinforcing cavity is arranged between every two adjacent closed cavities. The utility model greatly improves the ring stiffness of the corrugated pipe and enhances the bearing capacity by optimizing the shapes of the reinforcing rib, the reinforcing cavity and the closed cavity, thereby ensuring the construction progress and normal use.
Description
Technical Field
The utility model belongs to the technical field of pipes, and particularly relates to a reinforced spiral corrugated pipe.
Background
The polyethylene spiral corrugated pipe is a novel light pipe, has excellent performances of high pressure resistance, light weight, good toughness and the like, and is widely applied to municipal sewage pipeline engineering construction due to good pipe-soil combined action.
The ring stiffness is an important index for measuring the spiral corrugated pipe, if the ring stiffness of the corrugated pipe is not enough, the bearing capacity of the corrugated pipe is not enough, deformation can be caused in the construction or working process due to the fact that external pressure cannot be borne, and then the pipe body can be cracked or damaged seriously, so that the construction progress and normal use are influenced.
Therefore, how to solve the above-mentioned drawbacks of the prior art becomes the direction of efforts of those skilled in the art.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a reinforced spiral corrugated pipe which can completely solve the defects of the prior art.
The purpose of the utility model is realized by the following technical scheme:
the utility model provides a strenghthened type helical bellows, includes the body that banded panel spiral winding bonding formed, banded panel includes the base plate and sets up in three closed chamber about the base plate, is equipped with the stiffening rib in closed chamber, is equipped with the reinforcing chamber between two adjacent closed chambers.
Furthermore, the left closed cavity and the right closed cavity are symmetrically arranged, the outer side wall of each closed cavity is a vertical surface, and the inner side wall of each closed cavity is an arc-shaped surface.
Further, the middle closed cavity comprises a left side wall and a right side wall, and the left side wall and the right side wall are symmetrical to each other.
Furthermore, a vertical reinforcing rib is arranged in the middle of the reinforcing cavity.
Furthermore, horizontal reinforcing ribs are arranged in the left closed cavity and the right closed cavity, and cross reinforcing ribs are arranged in the middle closed cavity.
Furthermore, T-shaped reinforcing ribs are arranged in the left closed cavity and the right closed cavity, the top surfaces of the T-shaped reinforcing ribs are flush with the top surfaces of the reinforcing cavities, and vertical reinforcing ribs are arranged in the middle closed cavity.
Compared with the prior art, the utility model has the beneficial effects that: simple structure, reasonable in design have improved the ring rigidity of bellows by a wide margin through optimizing to set up stiffening rib, reinforcing chamber and closed chamber shape, have strengthened the bearing capacity, and then guarantee construction progress and normal use.
Drawings
FIG. 1 is a schematic diagram of an embodiment of the present invention;
fig. 2 is another structural schematic diagram of the pipe body of the present invention.
Detailed Description
The utility model will be further described with reference to specific embodiments and the accompanying drawings.
Example one
As shown in fig. 1, a reinforced helical bellows comprises a tube body formed by spirally winding and bonding strip-shaped plates, wherein each strip-shaped plate comprises a substrate 1 and three closed cavities arranged on the left, the middle and the right of the substrate, reinforcing ribs are arranged in the closed cavities, and a reinforcing cavity 2 is arranged between every two adjacent closed cavities. The base plate 1, the closed cavity, the reinforcing rib and the reinforcing cavity 2 are integrally formed. The cross section of the reinforcing cavity 2 is rectangular.
The left closed cavity and the right closed cavity 3 are symmetrically arranged, the outer side wall 31 of the closed cavity is a vertical surface, and the inner side wall 32 of the closed cavity is an arc-shaped surface.
The middle closed cavity 4 comprises a left side wall 41 and a right side wall 42, the left and right side walls 41, 42 are symmetrical to each other, and both the left side wall 41 and the right side wall 42 are arc-shaped walls. And a vertical reinforcing rib 5 is arranged in the middle of the reinforcing cavity 2.
The corrugated pipe has the advantages that the shape of the closed cavity is optimized through the arrangement of the reinforcing ribs and the reinforcing cavity, so that the ring stiffness of the corrugated pipe is greatly improved, the bearing capacity of the corrugated pipe is enhanced, and the construction progress and the normal use are further ensured.
Example two
As shown in fig. 1, the present embodiment is different from the first embodiment in that horizontal reinforcing ribs 6 are provided in the left and right closed chambers 3, and cross-shaped reinforcing ribs 7 are provided in the middle closed chamber 4.
EXAMPLE III
Referring to fig. 2, the difference between the present embodiment and the first or second embodiment is that T-shaped reinforcing ribs 8 are disposed in the left and right closed cavities 3, the top surfaces of the T-shaped reinforcing ribs 8 are flush with the top surface of the reinforcing cavity 2, and vertical reinforcing ribs 9 are disposed in the middle closed cavity 4.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
