Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water supply and drainage, and particularly refers to a drain pipe with shear and compression resistance. Background Art
[0002] Among the buried pipes designed with wave crests on the market, there are double-wall steel belt corrugated pipes, inner rib pipes and Klargester pipes. The double-wall steel belt corrugated pipes use steel sheets to enhance the wave crests and the pipe body to improve the overall strength. However, the specific gravity difference between the steel sheet and the plastic is too large and they do not fuse with each other, resulting in separation during operation, short service life and high cost; the inner rib pipe and other methods mainly aim to enhance the wave crests and do not solve the problem of shear resistance of the blank pipe body between the wave crests; the Klargester pipe winds a whole small pipe spirally around the pipe body to enhance the connection between the wave crests and play a role of mutual force. The spiral structure has a telescopic movement amount. This structure enhances the connection between the wave crests but does not completely solve the problem that the pipe body between the wave crests is vulnerable to shear force and needs to be improved. Content of the Utility Model
[0003] In view of the above problems, the utility model provides a drain pipe with shear and compression resistance to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0005] A drain pipe with shear and compression resistance includes a pipe body. A plurality of groups of reinforcing rib groups are arranged on the outer wall of the pipe body. Two adjacent groups of reinforcing rib groups are in contact with each other and form a plurality of contact points. The plurality of contact points on the same group of reinforcing rib groups are not on the same cross-section of the pipe body.
[0006] Preferably, each group of the reinforcing rib groups is composed of one or more reinforcing ribs of the same shape arranged side by side.
[0007] Preferably, each group of the reinforcing rib groups is annular.
[0008] Preferably, the connection line of the plurality of contact points along the axial direction of the pipe body is not parallel to the axis of the pipe body.
[0009] Preferably, the connection line of the plurality of contact points along the axial direction of the pipe body is spiral.
[0010] Preferably, the reinforcing rib and the pipe body are integrally formed plastic pipes.
[0011] Preferably, the cross-section of the reinforcing rib is semi-circular or semi-elliptical.
[0012] Preferably, a reinforcing framework is added to the reinforcing rib at a position close to the contact point.
[0013] Advantages of the Utility Model
[0014] 1. The utility model improves the technical problem of poor shear and compressive resistance between the wave crests of the corrugated pipe by providing multiple contact points between adjacent reinforcing rib groups, and improves the compressive and shear resistance of the pipe.
[0015] 2. By making the connecting line of the contact points along the axial direction of the pipe body spiral, the shear and compressive resistance of the pipe is improved.
[0016] 3. By making the connecting line of the multiple contact points in the axial direction of the pipe body not parallel to the cross-section of the pipe body, the shear resistance of the pipe is improved.
[0017] 4. By providing more than one reinforcing rib with the same shape and arranged in parallel in the reinforcing rib group, the compressive and shear resistance of the reinforcing rib group is improved.

[0023] The technical solution of the utility model will be described below in conjunction with the drawings and embodiments.
[0024] Referring to Figures 1 to 2 , a shear and compression resistant drain pipe according to the utility model includes a pipe body 1, and a reinforcing rib group composed of reinforcing ribs 2 is annularly provided on the outer wall of the pipe body 1. Multiple contact points 3 are formed by the abutment between adjacent reinforcing rib groups, so that the reinforcing rib group is approximately wave-shaped and annularly provided on the outer wall of the pipe body 1. The reinforcing rib group has wave crests 5 and wave valleys 4 along the axial direction of the pipe body 1. The wave valley 4 of the previous reinforcing rib group abuts against the wave crest 5 of the next reinforcing rib group. By providing the reinforcing rib 2, the shear resistance in the radial direction of the pipe body 1 is improved. By providing multiple contact points 3 between adjacent reinforcing rib groups, the pressure received by the pipe body 1 can be sequentially conducted from the front end to the rear end to the reinforcing rib 2. The reinforcing ribs 2 on both sides of the wave crest 5 and the wave valley 4 of the reinforcing rib 2 are inclined, and part of the pressure borne by the reinforcing rib 2 is converted into the pressure of the reinforcing ribs 2 on both sides of the wave crest 5 and the wave valley 4, improving the compressive capacity in the axial direction of the pipe body 1, and at the same time solving the problem of poor shear resistance between the wave crests of the existing corrugated pipe.
[0025] Specifically, the reinforcing rib group is composed of more than one reinforcing rib 2 with the same shape arranged side by side. The reinforcing rib group composed of multiple reinforcing ribs 2 with the same shape arranged side by side has stronger compressive and shear resistance capabilities.
[0026] Specifically, the connection lines of multiple contact points 3 in the axial direction of the pipe body 1 are not parallel to the axis of the pipe body 1, which is conducive to dispersing the axial force of the pipe body 1 and improving the axial compressive capacity of the pipe body 1.
[0027] Specifically, the connection lines of multiple contact points 3 in the axial direction of the pipe body 1 are spiral, which is conducive to dispersing the axial force of the pipe body 1 and improving the axial compressive capacity of the pipe body 1.
[0028] Specifically, the reinforcing rib 2 and the pipe body 1 are integrally formed plastic pipes. Integrally forming the reinforcing rib 2 and the pipe body 1 improves the compressive and shear resistance capabilities of the pipeline.
[0029] Specifically, the cross-section of the reinforcing rib 2 is semi-circular or semi-elliptical. During construction, the frictional force of the soil on the surface of the semi-circular or elliptical reinforcing rib 2 is smaller, and the shear force on the reinforcing rib 2 is smaller.
[0030] Specifically, a reinforcing framework is added to the reinforcing rib 2 at a position close to the contact point 3 to improve the strength of the reinforcing rib at the contact point 3 and its compressive strength.
