Embodiment Construction
[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0022] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0023] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations...

The invention discloses a water sealed connection device for splicing building cement pipes. The water sealed connection device comprises the cement pipes (1), a connecting sleeve (2), hexagonal arc section rubber rings (3), super absorbent resin (SAP) (4) and elastic permeable annular accommodation belts (5); and the SAP (4) is placed in the elastic permeable annular accommodation belts (5), a round of rectangular grooves (6) are formed in the inner wall, close to the ends, of the connecting sleeve (2), and a round of semi-circular grooves (7) are formed in the outer walls, close to the ends,of the cement pipes. The hexagonal arc section rubber rings are placed in the rectangular grooves, two annular voids are formed in two right angles of the rectangular grooves, and the elastic permeable annular accommodation belts are correspondingly placed in the voids. The elastic permeable annular accommodation belts are also correspondingly placed in the semi-circular grooves. When splicing isconducted, the connecting sleeve moves from the ends of the cement pipes to the middle of an inner pipe with the help of external force in the pipe axial direction until the semi-circular grooves inthe outer walls of the cement pipes are completely covered with the outer side arc surfaces of the hexagonal arc section rubber rings.
Description
technical field [0001] The invention relates to the field of engineering construction, in particular to a water-tight connection device used for splicing construction cement pipes. Background technique [0002] Construction cement pipe is the main material used in road and bridge engineering, power cable engineering and construction engineering. Cement pipes are usually buried directly in the ground and are used to pass cables and protect them; they can also be used for drainage and sewage. In order to facilitate transportation, cement pipes usually have a multi-section structure and are spliced during use. At present, most of the splicing methods are butt joints or connections. The sealing of the joints is often not guaranteed, and water and other liquids are easy to seep into the pipes. And the structure itself causes certain pollution and corrosion; if it is used for drainage and sewage, the sewage in the pipeline is easy to leak out, and the bearing capacity of each s...
