Embodiment

[0019] The implementation process of this example is as follows: first adopt the autoclaved aerated concrete blocks of 200 * 200 * 600mm to build a long 3.8 meters, a width of 2.0 meters, and a sedimentation tank 8 of 0.9 meters high on the ground 7 near the elevator shaft 1. Two partition walls 14 are built with autoclaved aerated concrete blocks in the sedimentation tank 8, and the sedimentation tank 8 is divided into a primary sedimentation tank 11, a secondary sedimentation tank 12 and a tertiary sedimentation tank 13 through the partition walls 14. An overflow hole 15 is left on each partition wall 14 . The two overflow holes 15 are arranged diagonally to increase the residence time of the sewage in the sedimentation tank 8, so that the sewage can be more fully settled. The surfaces of the sedimentation tank 8 and the partition wall 14 should be smoothed, and waterproof treatment should be done in the sedimentation tank 8 .

Abstract

The invention discloses a method and device for recycling pump washing water in floor construction. The method comprises the following steps: firstly, building a sedimentation tank on the ground nearan elevator shaft of a building; fixing an upper corrugated pipe on a steel pipe bracket in the elevator shaft of the building; allowing a water outlet of the corrugated pipe to be led into a sedimentation tank; and then placing a funnel at the water inlet of the corrugated pipe of an operation floor. Thus, pump lubricating mortar or the pump washing water can be directly discharged into the waterinlet of the corrugated pipe through a water discharging pipe and the funnel and flows into the sedimentation tank, and clear water obtained after the pump lubricating mortar or the pump washing water is settled in the sedimentation tank is used as water for cement maintenance or construction. The method overcomes the technical problem that pump lubricating mortar and waste water produced after cleaning of a pump pipe have nowhere to be discharged and are directly discharged to an elevator shaft during high-rise building construction and consequently cause environmental pollution. The deviceis simple in structure and easy to implement, overcomes the problem of environmental pollution in the prior art, lowers the consumption of construction water, and reduces construction cost.

Description

technical field [0001] The invention relates to a method and a device for reusing washing pump water for floor construction, and belongs to the technical field of construction environment protection. Background technique [0002] In the concrete pouring construction of buildings, the pouring method of ground pump and distribution machine is usually used, and the concrete is conveyed by the pump pipe from the ground to the construction floor. For the standard floor and higher floors, it is a relatively mature set. pouring method. With the increase of the floor, the cleaning of the pump mortar and the pump pipe has become a long-standing and difficult problem. Many construction units poured the pump moistening mortar and pump washing water into the elevator shaft for convenience, resulting in the accumulation of concrete slag in the elevator shaft in the later stage and it was difficult to clean up. It does not meet the requirements of environmental protection and green cons...
