Problems solved by technology

In addition, due to a large amount of groundwater pumping, the ground collapses, cracks appear on the ground, and buildings crack and collapse, seriously affecting the safety and development of the city.
In some places, reservoirs are opened up as "second water sources", but due to the shortcomings of huge projects, large investments, and complicated water supply systems, it is not a good measure.

Embodiment Construction

[0017] Choose a suitable place to dig a well, enclose the area to be constructed with a dam, the size of the enclosed area is convenient for construction, drain the water in the dam, insert the emergency pipeline 5 into the well, fill the surrounding area with soil and tamp it; The pipeline in the direction of the waterworks is connected with the tee pipeline 3, and the angle of the tee pipeline is adjusted so that the emergency pipeline can be connected with the tee pipeline, and the second valve 4 is set near the emergency pipeline near the tee pipeline; The water intake head 1 is connected to the three interfaces, and the first valve 2 is arranged between the water intake head and the three-way pipe. Clean up the site after all the work is done and remove the embankment. The entire water intake head should be below the water surface during the dry season.

[0018] Under normal circumstances, it is necessary to close the second valve 4 and open the first valve 2; when a sud...

Abstract

The invention relates to a bidirectional water taking device for emergency contamination accidents. The bidirectional water taking device comprises an emergency pipeline perpendicular to the horizontal plane, the upper end of the emergency pipeline is connected with a three-way pipeline, a first pipeline body of the three-way pipeline is connected with the emergency pipeline, a second pipeline body of the three-way pipeline is connected with a water supply pipeline, a third pipeline body of the three-way pipeline is connected with a water taking head, a first valve is disposed between the water taking head and the third pipeline body, and a second valve is arranged between the first pipeline body and the emergency pipeline. Further, the water taking head is in a cuboid structure with grids on four sides. By means of the bidirectional water taking device, conventional water taking and normal water taking when water source emergency contamination accidents occur can be achieved.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a water device, in particular to a two-way water intake device for emergency sudden pollution accidents. Background technique [0002] Water resources have a fundamental and irreplaceable status and role for human survival and development. The sustainable, effective, safe and environmentally friendly supply of urban water resources is the lifeline of urban population survival and social and economic development. However, many water sources are open and pose a potential threat to their own safety. [0003] Due to historical reasons and the gradual advancement of urban construction, water sources are intertwined with docks, chemical industry parks, and sewage outlets. 50%-80% of the water sources in cities along the river have hidden dangers to varying degrees. There are wharves or other enterprises, or the water intake is too close to the waterway, etc. The potential problem...
