Description

Connection device of concrete fume pipe

The present invention relates to a concrete fume pipe connecting device for efficiently constructing each concrete fume pipe in the concrete fume pipe used for draining the ground.

In general, concrete fume pipes used for drainage by laying on the ground during civil works are manufactured to a certain length for transportation or construction, and are used by connecting concrete fume pipes at the construction site, respectively. Is as follows.

Ring joints or splicing joints, which have been widely used in the past, are difficult to join cement mortar, and construction work is performed when the connection part of the concrete fume pipe is placed on the ground. It is possible, but the lower part in close contact with the ground was difficult to join, so in the concrete fume pipe, because the joint work is not made in the lower part where the sewage flows intensively, it was a direct cause of leakage.

In addition, since the connection methods of the concrete fume pipes are connected only when the connection parts of the concrete fume pipes are kept in a straight line in the correct state, careful care is required when placing the concrete fume pipes on the ground or placing each concrete fume pipe in the connection position. In addition, the utility model registration No. 98-442 filed in my proposal filed the reinforcement of the strength of the connection device that fills the cement mortar is not effective because of the weak or narrow space, causing a delay in the working time.

The present invention was devised to solve the above problems, and this conventional synthetic resin made of the connection part of the concrete fume pipe is connected to a rigid cylindrical connector by inserting a rigid cylindrical connector because it lacks the support for fluidity when the cement mortar is injected. It is a construction by filling cement mortar in the inside of the building. Since the height of the conventional side prevention zone is limited in the production process, it is easy to construct by forming a separate auxiliary hollow part and the connection part by fluidity or external impact of the connection part. Its purpose is to be able to use safely without being deformed or damaged, and in the case of large diameter, it is a design that the repair work is smoothly provided by assembling the formwork of the present design on the inner surface.
