Description

Technical Field

[0001] The utility model belongs to the field of municipal engineering, in particular to a permeable pipe used for permeable brick paving. Background Art

[0002] Green, water conservation, water storage and reduction of surface runoff have gradually become hot topics in society. These elements have also been incorporated into the road construction process, involving the construction of many permeable sidewalks. The surface layer of permeable sidewalks mostly uses permeable bricks, which have good permeability. The sidewalk base layer uses permeable concrete, which also has good permeability. However, the mortar sandwiched between the permeable bricks and the permeable concrete base has poor permeability, which causes the overall permeability of the sidewalk to be weakened. Because the mortar needs a certain degree of looseness during construction and the permeable bricks must be firmly fixed after solidification, it is currently difficult to make the sidewalk into a completely permeable structure. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the background technology and provide a permeable pipe for permeable brick paving.

[0004] The present invention is achieved through the following technical solutions:

[0005] A permeable pipe for permeable brick paving comprises an upper pipe and a lower pipe, the combined length of which is greater than the thickness of the mortar. Saw teeth A are symmetrically provided on both sides of the lower outer wall of the upper pipe. Saw teeth A are located in the upper pipe at positions corresponding to the upper pipe, and a chute is provided within the chute. A spring is provided within the chute, one end of the spring being secured to serration A. The other end of the spring is secured to the inner wall of the chute, and serration A can be retracted into the chute. Saw teeth B are symmetrically provided on both sides of the upper inner wall of the lower pipe, and can be engaged with serration A. Saw teeth A can move downward relative to serration B, but cannot move upward relative to serration B.

[0006] Preferably, the upper end of the upper tube and the lower end of the lower tube are both bell-mouthed.

[0007] Preferably, the sawtooth A and sawtooth B are both triangular sawtooths, the upper surface of sawtooth A is a horizontal plane, the outer side surface is a downward inclined surface and the angle between it and the upper surface is an acute angle, and the lower surface of sawtooth B is a horizontal plane, the outer side surface is an upward inclined surface and the angle between it and the lower surface is an acute angle.

[0008] Beneficial effects of the present invention:

[0009] 1. The permeable pipe of the present invention can allow the water that permeates the permeable bricks to flow into the permeable concrete base, greatly increasing the overall permeability of the pedestrian road.

[0010] 2. The height of the permeable pipe of the present invention can be changed according to the thickness of the mortar and the laying process. It will not be submerged in the mortar and lose its effect, nor will it be higher than the mortar and cause the permeable bricks to be uneven, thereby ensuring that the permeable bricks are firmly paved.

[0011] 3. The water inlet and outlet of the water-permeable pipe of the present invention are both trumpet-shaped, which can increase the water collection area and the water outlet area, and ensure the smooth flow of water. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0017] This embodiment comprises an upper tube 1 and a lower tube 2 that can be nested together. The inner diameter of the lower tube 2 is larger than that of the upper tube 1, and the total length of the upper tube 1 and the lower tube 2 is greater than the thickness of the mortar. Saw teeth A3 are symmetrically provided on both sides of the lower outer wall of the upper tube 1. A chute 4 is provided in the upper tube 1 at the position of the upper tube 1 corresponding to the saw teeth A3. A spring 5 is provided in the chute 4. One end of the spring 5 is fixed to the saw teeth A3, and the other end of the spring 5 is fixed to the inner wall of the chute 4. When the spring 5 is compressed by an external force, the saw teeth A3 can be retracted into the chute 4. When the external force disappears, the spring force can cause the saw teeth A3 to extend out of the chute 4 and return to their original state.

[0018] Saw teeth B6 that can match and engage with saw teeth A3 are symmetrically provided on both sides of the upper inner wall of the lower tube 2. Due to the presence of the spring 5, the saw tooth A3 can move downward relative to the saw tooth B6, but the saw tooth A3 cannot move upward relative to the saw tooth B6. Preferably, both sawtooth A3 and sawtooth B6 are triangular sawtooths, wherein the upper surface of sawtooth A3 is a horizontal plane, the outer side surface is a downwardly inclined surface, and the angle between the outer side surface and the upper surface of sawtooth A3 is an acute angle, while the lower surface of sawtooth B6 is a horizontal plane, the outer side surface is an upwardly inclined surface, and the angle between the outer side surface and the lower surface of sawtooth B6 is an acute angle. Then, when sawtooth A3 slides downward relative to sawtooth B6, sawtooth A3 is squeezed by sawtooth B6 and can be retracted into the slide groove 4, so that sawtooth A3 can slide downward relative to sawtooth B6. Due to the elastic force of spring 5, sawtooth A3 extends from the slide groove 4 and can engage with sawtooth B6. At this time, since the horizontal upper surface of sawtooth A3 and the horizontal lower surface of sawtooth B6 are tightly attached to each other, sawtooth A3 can no longer slide upward.

[0019] In order to increase the water collection area, the upper end of the upper tube 1 is set as a bell mouth. Similarly, in order to ensure the water outlet area, the lower end of the lower tube 2 is also set as a bell mouth.

[0020] When the present invention is used, the permeable pipe of the present invention is first placed on the permeable concrete base, and one is placed per square meter. The number of pipes to be placed can be determined according to the situation. When placing, the upper pipe 1 is on the top and the lower pipe 2 is on the bottom. The upper pipe 1 is placed inside the lower pipe 2. At this time, the length of the permeable pipe is greater than the designed mortar virtual paving thickness, that is, the upper surface of the permeable pipe is higher than the upper surface of the mortar to be virtual paved. Then, mortar is laid, and permeable bricks are laid on the mortar. When laying mortar, the permeable pipe should be avoided when laying mortar at the position where there is a permeable pipe. After the mortar is laid, the permeable bricks are pressed on the upper surface of the permeable pipe, and then the mortar is laid according to the mortar. The normal construction method is to gently tap the permeable bricks with a rubber hammer to make them solid, so that the permeable bricks are tightly and firmly combined with the mortar, and the upper surface of the permeable pipe is close to the lower surface of the permeable bricks. When tapping, the permeable pipe will lower its height downward along with the permeable bricks. The tapping force of the rubber hammer causes the sawtooth A3 to slide downward, and finally the height of the upper surface of the permeable pipe is equal to the height of the upper surface of the mortar. The upper surface of the permeable pipe is close to the lower surface of the permeable bricks. In the later stage, the water that penetrates the permeable bricks will flow into the permeable pipe, and then flow into the permeable concrete base through the permeable pipe, which greatly improves the permeability of the overall structure.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
