Device and method for flushing gravel using recirculated water at construction site

Abstract

The invention relates to a device for flushing stones with circulating water at a construction site and a method thereof. The device comprises a filtering system, a settling system and a flushing system, wherein, the filtering system consists of a gradient rising table and a filter basin which forms a filter channel by a fence and is provided with a filler; a settling basin and a collecting well of the settling system are communicated with each other by a blind ditch; and the flushing system is provided with a water pump and a rotatable water gun. The flushing steps are as follows: the stones are flushed with a common tapping pipe, when the settling basin and the collecting well are filled with water, the tapping pipe is closed, the water pump is turned on, then the flushing is carried out when the rotatable water gun aims at a car hopper; the muddy water from flushing the stones flows into the filtering basin, most silt settles at the bottom of the filtering basin when the muddy water flows through the filtering basin, then the muddy water flows into the settling basin by the filtering channel for settling, after settling, the water at the upper section of the settling basin is relatively clear and runs into the collecting well by the blind ditch, and then the water is pumped by a water pump for recycling. The device has low cost, and the method is easily achieved and has good effect, which are favorable for settling and silt discharging.

Description

technical field [0001] The invention relates to a device and method for washing stones with circulating water at a building construction site through filtration and sedimentation so that the water for washing stones can be recycled. Background technique [0002] For the frame structure of construction engineering, the amount of concrete is relatively large, such as 5600m 3 The amount of concrete in the frame structure above, in order to improve the quality of the project, the construction often requires that all the concrete of the project need to be mixed on site. If the local stones contain a lot of mud, the stones need to be washed with water to meet the requirements of the construction quality before they can be mixed with cement. Qualified concrete is made. In this case, the washing of stones for concrete mixing has become one of the key monitoring of project quality. [0003] According to the traditional method in the past, the washing of the stones is directly washed...

Problems solved by technology

[0003] According to the traditional method in the past, the stones are washed directly with tap water, and the water after washing the stones is allowed to flow away. At this time, the water consumption is large and the waste is more prominent.

Another way is to use the sump to collect the used water. The washing process is carried out directly above the sump, and the water in the sump is recycled to wash the stones. Although this method can use circulating water to wash the stones, it is not purified device, the effect of washing stones is not ideal, and the water pump set in the sump is easily blocked by sedimented mud

The flushing operation is difficult to perform as the flushing process takes place directly above the sump

At the same time, it is not convenient to clean up the mud after washing for a period of time
