Description
Technical Field
The invention belongs to the technical field of drainage pipelines, and particularly relates to an anti-leakage and anti-blocking drainage pipeline.
Background
Municipal works are generally national infrastructures, which refer to infrastructures such as various public transportation facilities, water supply, drainage, gas, urban flood control, environmental sanitation and lighting in urban construction, are material foundations essential for urban survival and development, and are basic conditions for improving the living standard of people and opening the people to the outside. Present town road both sides, the mill, drainage pipe in the residential block is in actual operation, because the difference of different time quantums water consumption, lead to at the low peak period that the water consumption is less, the pipeline internal pressure is little, the velocity of flow is lower, and sewage in the pipeline contains impurity usually, silt, the leaf etc., produce the natural settlement in the pipeline, lead to the pipe blockage and unable normal use, simultaneously in municipal construction process, often can use the excavator, often can take place the condition that the scraper bowl damaged drainage pipe, sometimes only damage pipeline top a small part region, also need change whole pipeline.
Therefore, CN206829311U discloses an anti-clogging drainage pipe for municipal engineering, which is characterized in that a pipe body is assembled by arranging an upper half shell and a lower half shell which are spliced, and in a time period with low water consumption, because the inner diameter of the lower half shell is small, the flow velocity in the pipe is still kept in a high state, so as to achieve the effect of preventing clogging; in the time period of high water consumption, the upper half shell still has the function of providing enough drainage efficiency due to the larger inner diameter of the upper half shell.
However, the waterproof material is coated at the joint of the upper half shell and the lower half shell, when the upper half shell and the lower half shell are assembled, the waterproof coating is very easy to scrape off, the sealing performance of a drainage pipeline is poor, the road surface sinks due to leakage, soil and underground water on two sides of the pipeline are polluted, and the service life of the pipeline is seriously shortened. Moreover, it should be noted that although the anti-corrosion layer coated on the inner wall of the pipe can play a role of preventing leakage to some extent, the anti-corrosion layer can be scraped by particulate matters in sewage, and therefore, the sealing performance of the drainage pipe of the invention is poor.
Disclosure of Invention
In order to solve the problems, the invention provides the anti-leakage and anti-blocking drainage pipeline which has a good anti-leakage effect, can avoid the sinking of a road surface, prevents sewage from polluting the environment and has a long service life.
The invention is realized by adopting the following technical scheme:
the utility model provides an antiseep, prevent blockking up drainage pipe, includes that the appearance is the pipeline body of cylinder, the pipeline body is formed by first half casing and lower half casing concatenation, first half casing respectively is equipped with at least one upper groove along radial direction both ends, lower half casing respectively is equipped with the lower groove that corresponds and quantity equals with the upper groove along radial direction both ends, the upper groove forms the seal groove with the lower groove amalgamation, the inside of seal groove is equipped with the sealing strip.
Preferably, the shape of the sealing groove is a cuboid, and the width of the sealing groove is larger than 2 cm.
Preferably, the height of the upper groove is less than or equal to the height of the lower groove.
Preferably, the height of the upper groove is a, the height of the lower groove is b, and a and b satisfy 0.4b ≤ a ≤ 1 b.
Preferably, two ends of the upper half shell in the radial direction are respectively provided with two upper grooves, and two ends of the lower half shell in the radial direction are respectively provided with two lower grooves corresponding to the upper grooves.
Preferably, the sealing strip is made of fluororubber.
Preferably, the outer diameters of the upper half shell and the lower half shell are the same, and the inner diameter of the lower half shell is smaller than or equal to the inner diameter of the upper half shell.
The invention has the beneficial effects that:
1. the pipeline body is formed by splicing the upper half shell and the lower half shell, when the bucket damages the top area of the drainage pipeline, only the upper half shell needs to be replaced, so that the cost is saved, the replacement difficulty is reduced, and the maintenance efficiency is improved.
2. The sealing strip embedded between the upper half shell and the lower half shell can greatly improve the sealing property of the pipeline body, ensure that sewage in the pipeline body does not leak to erode the connecting surface of the upper half shell and the lower half shell and soil and concrete structures around the pipeline body, and greatly improve the service life of the pipeline body.
3. The sealing groove is in a cuboid shape, so that the sealing strip is easy to install, the installed sealing strip is filled in the sealing groove, the width of the sealing strip is at least 2cm, certain pressure resistance can be formed in the radial direction of the pipeline, a good compression effect can be formed between the sealing strip and the upper half shell and between the sealing strip and the lower half shell, and a good sealing effect can be obtained.
4. When the sealing strip is clamped into the lower groove, the lower groove can form a better positioning effect on the sealing strip because the height of the upper groove is less than or equal to that of the lower groove, the mounting difficulty of the sealing strip and the upper half shell on the lower half shell is reduced, the mounting efficiency is improved, and the sealing strip is not easy to shake after being positioned, so that the sealing effect of the sealing strip when the upper half shell is mounted is ensured, and the anti-leakage effect of a product is ensured.
5. The outer diameters of the upper half shell and the lower half shell are the same, and the inner diameter of the lower half shell is smaller than or equal to the inner diameter of the upper half shell. In the time period of low water consumption, such as night, the flow velocity in the pipeline still keeps a higher state due to the smaller inner diameter of the lower half shell, thereby playing the effect of preventing blockage; in the time period of high water consumption, the upper half shell still has the function of providing enough drainage efficiency due to the larger inner diameter of the upper half shell.
