Description
Technical Field
The utility model belongs to the technical field of municipal engineering, and particularly relates to a pipe well connecting and sealing device.
Background
In view of the current municipal rainwater and sewage pipe network construction situation, the pipe material adopts an HDPE winding structure wall B-shaped pipe and a nano modified high-density polyethylene alloy pipe or other polyethylene pipe material, the inspection well adopts a prefabricated inspection well or a cast-in-situ inspection well, and the joint of the two is usually bonded by concrete or enveloped by concrete, and the expansion coefficients of the two are different, so that water leakage is caused; the plastic pipe is made of flexible materials, the concrete inspection well is made of rigid materials, the conditions of loose connection or end damage and the like can occur in the installation process, so that hidden danger of water leakage is formed, meanwhile, the quality of concrete used in bonding is difficult to control, so that the conditions of water leakage, concrete cracking, pipe damage and the like at the joint are caused, and the water closing test and acceptance qualification rate of pipe network engineering are greatly reduced; meanwhile, according to the fact that the sizes of the opening apertures of the prefabricated inspection wells are different, the prefabricated inspection wells cannot be perfectly matched with the pipe, and often the prefabricated inspection wells are required to be reamed, so that the operation efficiency is reduced, and the connection quality is correspondingly reduced after the reaming; pipe network leakage water and environmental pollution are caused by crack deformation and the like at rigid connection parts caused by sinking deformation and the like of pipes and inspection wells, so that a pipe well connection sealing device is required to be designed to solve the problems.
Disclosure of Invention
The utility model aims to solve the technical problem of providing the pipe well connecting and sealing device, which solves the problem of poor sealing performance of the pipe well connecting device in the prior art and has the characteristic of realizing good pipe well butt joint sealing.
In order to solve the technical problems, the utility model adopts the following technical scheme: the pipe well connecting and sealing device comprises a well side sealing ring, wherein the surface of the well side sealing ring is provided with an opening which is in plug-in fit with the spiral winding pipe; the upper surface of the well side sealing ring is integrally connected with a pipe side sealing ring, and the pipe side sealing ring is provided with an opening which is in splicing fit with the spiral winding pipe.
Preferably, the inner wall of the pipe side sealing ring is provided with an internal thread in threaded connection with the spiral winding pipe.
Preferably, an expansion water stop is connected to the open end of the tube-side seal ring.
Further, the pipe side sealing ring and the well side sealing ring are made of flexible rubber materials, so that certain elastic deformation can be generated when the pipe well is deformed, and sealing failure is avoided.
Further, the expansion water stop is a water stop which expands when meeting water.
The beneficial effects of the utility model are as follows:
the product can be closely attached to the pipe and the inspection well, so that the water leakage phenomenon is avoided; compared with the connection of mortar masonry, the product has the advantages that the connection quality of the pipe is easier to control, and only the qualification of rubber materials, the water resistance, the corrosion resistance, the water resistance of the sealing ring and the like are required to be controlled; the device is directly used for installation on an operation site, has low technical requirements, can greatly improve the qualification rate by slightly training operators, has uncomplicated technology and high safety performance; if the pipe and the inspection well subside to a certain extent after the post backfill, the rubber material of the product has certain elastic deformation, cannot crack, and avoids the water leakage phenomenon.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
the reference numerals in the drawings are: well side sealing ring 1, pipe side sealing ring 2, internal thread 3, expansion waterstop 4.
Detailed Description
Examples:
as shown in fig. 1, the pipe well connecting and sealing device comprises a well side sealing ring 1, wherein an opening is formed in the surface of the well side sealing ring 1 and is in plug-in fit with a spiral winding pipe; the upper surface of the well side sealing ring 1 is integrally connected with a pipe side sealing ring 2, and the pipe side sealing ring 2 is provided with an opening hole for being in plug-in connection with the spiral winding pipe.
Preferably, the inner wall of the pipe side sealing ring 2 is provided with an internal thread 3 which is in threaded connection with the spiral winding pipe.
Preferably, the open end of the tube-side seal ring 2 is connected with an expansion water stop 4.
Further, the pipe side sealing ring 2 and the well side sealing ring 1 are made of flexible rubber materials, so that certain elastic deformation can be generated when the pipe well is deformed, and sealing failure is avoided.
Further, the expansion water stop 4 is a water stop which expands when meeting water.
The working principle of the pipe well connecting and sealing device is as follows:
when the pipe is used, the inner thread 3 meshed with the HDPE spiral winding pipe is arranged in the pipe to ensure tight combination, and the outer part is tightly attached to the sewage well to ensure tight connection between the pipe and the inspection well.
The foregoing embodiments are merely preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without collision. The protection scope of the present utility model is defined by the claims, and the protection scope includes equivalent alternatives to the technical features of the claims. I.e., equivalent replacement modifications within the scope of this utility model are also within the scope of the utility model.
