Description

Expansion joint for sewage pipe

Technical Field

The utility model relates to a construction field especially relates to an expansion joint for blowdown pipe.

Background

When the high-rise building is constructed, a ground pump and a distributing machine are required to be used for pouring concrete, after the pouring is completed, the ground pump and the distributing machine are required to be flushed by pressurized water, and sewage after flushing is discharged outwards from a hose of the distributing machine and flows into a collecting device on the ground through a sewage discharge pipeline.

The sewage draining pipeline is a pipeline for draining sewage generated during the construction of a high-rise building to the ground, the sewage draining pipeline is formed by serially splicing a plurality of sewage draining pipes according to the height of the high-rise building, the height standard of a single-section sewage draining pipe is 3 meters, the floor height of different projects is not 3 meters, if the height of a certain project floor is 2.9 meters, after the sewage draining pipes are serially spliced, the height potential of the sewage draining pipe at the topmost layer is necessarily higher than that of the topmost layer floor, because a material distributor drives a hose to swing in the washing process, the hose needs to be moved up by constructors, and the hose is connected to the outlet of the sewage draining pipe in a labor-consuming manner, the operation is time-consuming and labor-consuming, the sewage is extremely easy to overflow, and the scaffold is seriously polluted.

The existing solutions are of two types, one mode is to cut off a single sewage draining pipe to enable the height of the sewage draining pipe to be consistent with the height of each floor, and to enable the sewage draining pipe at the top floor and the floor level of the top floor to keep horizontal positions, but the mode can cause the sewage draining pipe to be incapable of being reused, thereby causing waste and increasing the construction cost; the other mode is that the funnel is installed at the top of the top-layer blow-off pipe, the butt joint diameter of the funnel and the hose is increased, the butt joint of the hose of the distributing machine is facilitated, however, due to the fact that the height difference still exists, the overflow of sewage cannot be avoided.
