Description
Technical Field
[0001] The utility model relates to the technical field of concrete delivery pump pipe cleaning, in particular to a movable concrete pump pipe wastewater filtering pool. Background Art
[0002] After using pump pipes to pour concrete on the floor slabs of high-rise buildings, the pump pipes need to be cleaned in time, otherwise the residual concrete in the pump pipes will solidify, causing the pump pipes to be blocked or even scrapped. Pump pipe flushing wastewater is usually discharged to sedimentation tanks through pipes or drains. Because the flow path of sewage is very long, and pipes and drains are often narrow and restricted by the terrain, flushing wastewater can easily cause pipes and drains to be blocked, and cleaning them up consumes a lot of manpower and financial resources. Especially for buildings in the middle of group projects, there are no conditions for repairing drains, and the concrete residues and sewage washed out are discharged in an unorganized manner, which not only wastes materials, but also seriously affects the cleaning of the floors. A lot of manpower and material resources will be required for cleaning in the later stage.
[0003] Therefore, the Chinese utility model patent with the authorization announcement date of 2012.10.03 and the authorization announcement number CN 202466720 U discloses a discharge device for cleaning materials of concrete delivery pump pipes in high-rise building construction, including a cleaning pool arranged on the poured concrete floor slab of the high-rise building, and a fixed filter screen is arranged in the cleaning pool. The filter screen divides the cleaning pool into a cleaning area and a drainage area. The larger stones are filtered through the filter screen to remain in the cleaning area and then settle at the bottom of the pool. The filtered sewage flows along the drainage pipe on the pool wall of the drainage area through the vertical drainage pipe of the building to the sewage ditch or sewage pipe on the ground.
[0004] The above-mentioned discharge device has changed the current situation of disorderly discharge of pump pipe cleaning wastewater, but the filter screen only filters larger stones, and the fine sand in the sewage may still block the pipes or drains. Moreover, the filtered concrete stones are deposited in the cleaning area, and the cleaning pool is set on the floor, which causes inconvenience to the recycling of concrete stones.
