Description

Technical Field

[0001] The utility model belongs to the technical field of municipal pipeline grooving construction, and more specifically relates to a template device used for pipeline plugging construction. Background Art

[0002] There are many existing methods for permanent pipe plugging, including brickwork plugging, cast-in-place concrete plugging, etc. During the plugging period, the water in the pipe needs to be pumped out and temporarily plugged with air bags, and water can only be passed after the brick wall and concrete reach the designed strength. When part of the pipeline network does not meet the conditions for temporary plugging and the pipeline still needs to be kept running during construction, the above methods will no longer be feasible. Therefore, it is necessary to design a template device for pipeline plugging construction to solve the above problems. Summary of the invention

[0003] The purpose of the utility model is to provide a template device for pipeline plugging construction, which has fast on-site construction speed and is processed in a processing plant before plugging. There is no need to set up the template on site, and the template's own rigidity can be relied on to support the lateral pressure of concrete; when the water level in the pipeline is not higher than the template, water can be used for operation without pumping and temporary plugging; when the water level in the pipeline is higher than the template, it only needs to be pumped down to below the template elevation line, and the original pipeline can still maintain operation; there is no need to wait for the concrete strength to reach the designed strength, and the water scouring surface is the steel plate surface; at the same time, it can save costs, reduce losses such as plugging, backflow, and shutdown compensation, reduce the investment of construction personnel, and reduce the difficulty of coordination.

[0004] In order to realize the above technical features, the technical solution adopted by the utility model is:

[0005] A template device for pipeline plugging construction includes a first steel mold, the first steel mold includes a back plate, and a plurality of side wing plates are vertically connected to the side of the back plate; a second steel mold is connected to a side surface of the first steel mold through a screw rod, and the second steel mold extends into the interior of the pipeline to cooperate with the pipeline.

[0006] Preferably, the back plate of the first steel mold is a rectangular structure, and the side length of the back plate is greater than the diameter of the pipe; the side wing plates are rectangular structures; and the side wing plates at the bottom are in contact with and cooperate with the bottom of the well chamber.

[0007] Preferably, an armpit corner brace is connected between the back panel and the side wing panels.

[0008] Preferably, a plurality of first bolt holes with oblong hole structures are provided on the surface of the back plate.

[0009] Preferably, the second steel mold is a circular structure with a diameter smaller than the diameter of the pipe.

[0010] Preferably, a plurality of second bolt holes with circular hole structures are opened on the surface of the second steel mold, and the second bolt holes are connected to the first bolt holes of the first steel mold through screw rods.

[0011] The beneficial effects of the utility model are:

[0012] The utility model has a fast on-site construction speed, and is processed in the processing plant before plugging. There is no need to set up templates on site, and the template's own rigidity can be relied on to support the concrete lateral pressure. When the water level in the pipeline is not higher than the template, it can be operated with water, without pumping and temporary plugging. When the water level in the pipeline is higher than the template, it only needs to be pumped down to below the template elevation line, and the original pipeline can still maintain operation. There is no need to wait for the concrete strength to reach the design strength, and the water flushing surface is the steel plate surface. It saves costs, reduces losses such as plugging, reverse discharge, and shutdown compensation, and reduces the investment of construction personnel; it also reduces the difficulty of coordination.
