Pipe clamp of lost foam

Abstract

The invention relates to a pipe clamp of a lost foam. The pipe clamp is provided with a pipe clamp matrix which is constituted by a spigot pipe clamp and a socket pipe clamp, wherein the spigot pipe clamp is provided with a first and a second semicircle spigot pipe clamp units; one end and the other end of the first semicircle spigot pipe clamp unit are both provided with a first spigot bolt connecting hole; the side wall of the first semicircle spigot pipe clamp unit is provided with a first fixed bolt connecting hole; one end and the other end of the second semicircle spigot pipe clamp unit are both provided with a second spigot bolt connecting hole; and the side wall of the second semicircle spigot pipe clamp unit is provided with a second fixed bolt connecting hole. The socket pipe clamp is provided with a first and a second semicircle socket pipe clamp units; one end and the other end of the first semicircle socket pipe clamp unit are both provided with a first socket bolt connecting hole; the side wall of the first semicircle socket pipe clamp unit is provided with a third fixed bolt connecting hole; one end and the other end of the second semicircle socket pipe clamp unit are both provided with a second socket bolt connecting hole; and the side wall of the second semicircle socket pipe clamp unit is provided with a fourth fixed bolt connecting hole.

Description

technical field [0001] The invention relates to a quick installation device for a water supply pipeline, in particular to a lost foam pipe collar. Background technique [0002] The existing pipe collar is mainly used for fixing the position of the pipe fitting or temporarily sealing the leakage of the pipe fitting during emergency repair. For example, Chinese invention patent application No. 200610068621.9 discloses a quick repair method for tap water pipelines and its special pipe collar. At the leakage place, just tighten the flanges on both sides of the pipe clamp evenly. The special pipe clamp is provided with flanges on both sides of the pipe clamp body, and there is an integrated Γ-shaped groove on the periphery of the butt joint surface of the flange and the pipe clamp body. , The Γ-shaped sealing strip slides in and is embedded in the groove. The vertical side of the Γ-shaped sealing strip is oval. Another example is a pipe collar disclosed in Chinese invention pat...

Problems solved by technology

[0003] However, large-diameter cast iron pipes are used in the installation process of existing urban water supply pipes, and the connection or fixation of urban water supply pipes, pipe fittings and corners is usually only directly connected by flanges. Due to the weight of large-diameter cast iron pipes Huge, the joints of pipes, pipe fittings and turns often need to make buttresses to support the weight of the pipe itself and the weight of the internal fluid, so as to prevent the pipes from falling due to their own weight and cause the joints to loosen and cause leakage accidents. It takes a lot of manpower and material resources to make the buttresses And it is necessary to increase the excavation area of ​​the pipeline connection; and because of the intricate design of the urban underground pipeline network, it is impossible to make too much careful consideration in advance, the geological conditions at the installation pipeline are harsh, the construction scope is limited by the excavation conditions, and there is no difficulty in making temporary buttresses. The large excavation space often makes it impossible to have a buttress at the connection of the pipeline, which makes the connection of the urban water supply pipeline a potential leak
