Problems solved by technology

[0003] Existing water conservancy projects usually use cement pipes when pre-burying water diversion pipes. When the spliced ​​cement pipes are not tightly sealed, water will leak from the gap for a long time and pipe surges will occur. The existing sealing method is to apply sealing materials at the joints. more inconvenient

Embodiment 1

[0024] Example one, as Figure 1-6 As shown, it includes two cement pipes 1 spliced ​​in sequence, the outer surface of the joint of the cement pipes 1 is sleeved with a rubber gasket 2, and the surface of the rubber gasket 2 is provided with a through hole 3 that penetrates the rubber gasket 2, and the number of the through holes 3 is Two, one of the through holes 3 is located at the top of the middle of the rubber gasket 2 and the other through holes 3 are located on one side. Through this setting, the through hole 3 at the lower end can be used for injection, and the through hole 3 at the uppermost end is exhausted so that the interior is filled. The sealant can be evenly distributed, and it is ensured that the gap is filled when the sealant is discharged from the through hole 3 at the upper end.

[0025] The interior of the cement pipe 1 is clamped with a fixing mechanism 4, and one end of the fixing mechanism 4 located inside the cement pipe 1 is clamped with a sealing me...

Abstract

The invention provides a cement pipeline attaching device for a water conservancy project, and relates to the field of water conservancy projects. The cement pipeline attaching device for the water conservancy project comprises two cement pipes which are sequentially spliced, the outer surfaces of the connecting positions of the cement pipes are sleeved with rubber gaskets, through holes penetrating through the rubber gaskets are formed in the surfaces of the rubber gaskets, fixing mechanisms are clamped into the cement pipes, and sealing mechanisms are clamped to the ends, located in the cement pipes, of the fixing mechanisms. Every two adjacent sealing mechanisms are connected in a clamped mode through a connecting mechanism, the fixing mechanism comprises a fixing sleeve, and a gear ring is rotationally connected to the middle of the fixing sleeve. According to the cement pipeline attaching device for the water conservancy project, a control shaft is pushed to inject gas in a piston sleeve into an air bag ring so that the air bag ring can expand to be attached to the inner wall of a cement pipe, a sealant is injected into the cement pipe through a through hole in the lower portion, and the whole gap is filled with the sealant; the problem that sealant injection is inconvenient in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of water conservancy projects, in particular to a cement pipeline bonding device for water conservancy projects. Background technique [0002] A water conservancy project is a project built for the purpose of controlling and deploying natural surface water and groundwater to achieve the purpose of eliminating harm and increasing profits. Also known as water engineering. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent flood disasters, and adjust and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, embankments, spillways, sluice gates, water inlets, channels, ferries, rafts, fishways, etc., to achiev...
