AI Technical Summary
When traditional concrete wells are connected to pipelines, the construction space is small, resulting in the cement mortar not dense, and it is prone to hollowing. Due to soil settlement, groundwater floating and cement mortar fluidity, water seepage is prone to later on, causing environmental pollution and maintenance. Costs increase.
A combination device of sealing gasket, limiting ring and high-performance mortar is used. The sealing gasket is placed outside the pipe, and the limiting ring is close to the outside of the well wall. The filler uses high-performance mortar to enhance density and prevent the packing from shifting and loss.
The density of the concrete well and the pipeline connection is improved, the later maintenance costs are reduced, and the occurrence of water seepage is prevented.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete well and pipeline connection, in particular to a plugging device for connecting a concrete well and a pipeline. Background Art
[0002] When connecting the concrete well and the pipeline, a sealing structure is generally used at the connection between the two to make the connection between the two tighter and stronger.
[0003] When sealing the connection between the traditional concrete well and the pipeline, cement mortar is usually used to directly fill and smooth the connection between the two. However, this method has the following disadvantages: on the one hand, the small construction space will cause the cement mortar at the connection to be not densely poured, resulting in hollowing; on the other hand, due to soil settlement, groundwater buoyancy and the fluidity of the cement mortar itself, the connection is prone to water seepage in the later stage, causing environmental pollution, and the later maintenance requires secondary repairs, which increases the maintenance cost. Utility Model Content
[0004] The utility model aims to solve the above problem and provides a plugging device for connecting a concrete well and a pipeline.
[0005] The utility model is realized through the following technical scheme: a plugging device for connecting a concrete well and a pipeline, comprising an inspection well and a pipeline, a well hole is opened on the inspection well, the pipeline is inserted into the well hole, and a plugging device is arranged at the connection between the pipeline and the well hole, characterized in that the plugging device comprises a plugging gasket, a limiting ring and a filler, the plugging gasket is sleeved outside the pipeline, the outer wall of the plugging gasket is connected to the inner wall of the well hole, the plugging gasket is arranged in the middle position of the well hole, the front and rear sides of the plugging gasket are provided with fillers, the rear end of the rear side filler is provided with a limiting ring, and the limiting ring is arranged close to the outer side of the well wall.
[0006] Furthermore, the filler is high-performance mortar.
[0007] The beneficial effects of the utility model are as follows: the utility model makes the connection between the concrete well and the pipeline denser by setting a sealing gasket and a high-performance mortar for use together, and effectively prevents the filling material at the wellbore from shifting, misaligning and losing by setting a limit ring, thereby improving the density of the plugging and reducing the subsequent maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 It is a structural schematic diagram of the utility model.
[0009] Figure 2 This is a schematic diagram of a new type of installation structure used in this article.
[0010] In the attached drawings, 1 is an inspection well, 2 is a well hole, 3 is a pipeline, 4 is a limit ring, 5 is a filler, and 6 is a sealing gasket. DETAILED DESCRIPTION
[0011] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with embodiments.
[0012] like Figure 1 to Figure 2 As shown, a plugging device for connecting a concrete well and a pipeline 3 comprises an inspection well 1 and a pipeline 3, wherein a wellbore 2 is opened on the inspection well 1, the pipeline 3 is inserted into the wellbore 2, and a plugging device is provided at the connection between the pipeline 3 and the wellbore 2, characterized in that the plugging device comprises a plugging gasket 6, a limiting ring 4 and a filler 5, the plugging gasket 6 is sleeved outside the pipeline 3, the outer wall of the plugging gasket 6 is connected to the inner wall of the wellbore 2, the plugging gasket 6 is arranged in the middle position of the wellbore 2, the front and rear sides of the plugging gasket 6 are provided with fillers 5, the rear end of the rear side filler 5 is provided with a limiting ring 4, the limiting ring 4 is arranged close to the outer side of the wellbore wall, and the limiting ring 4 is used to prevent the plugging device from moving or misaligned.
[0013] In order to make the plugging more compact, filler 5 uses high-performance mortar.
[0014] When in use, first drill a wellbore 2 on the concrete well wall with a water drill, put the sealing gasket 6 on the outside of the pipe 3, then insert the pipe into the opened wellbore 2, and place the sealing gasket 6 between the wellbore 2 and the interlayer of the pipe 3, with the sealing gasket 6 in the middle of the wellbore 2, fill the front and side of the sealing gasket 6 with filler 5, and after filling, fix the limit ring 4 on the pipe 3 and set it close to the outer wall of the well.
[0015] Except for the technical features described in the specification, the other technical features are known to those skilled in the art.
