Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings and description of the accompanying drawings.
[0016] In the present invention, the submersible sewage pump 4, the escalator 8 and the maintenance platform 9 are included in the pump cylinder 12 and the pump cylinder 12. The submersible sewage pump 4 is hoisted at the bottom of the pump cylinder 12, and the maintenance platform 9 is arranged in the pump cylinder 12 In the middle and upper part, the escalator 8 is set between the maintenance platform and the upper port of the pump barrel 12, the ventilation and exhaust holes 1 are set on the upper part of the pump barrel 12, the water inlet 10 is set on the wall of the pump barrel 12, and the submersible sewage pump 4 is connected to the outlet pipe 3, The water outlet pipe 3 leads to the outside of the pump barrel 12 .
[0017] In the present invention, the pump cylinder 12 is made of an upper cylindrical body and a cyli...

The invention relates to a water conservancy project facility, in particular to a method for rectification of the bottoms of Archimedean screw grid bars of an integrated pump station, and belongs to the technical field of water conservancy projects and municipal engineering. The method is characterized in that a pump cylinder is formed by an upper cylinder body and a cylinder bottom, the cylinder bottom is a curved surface cylinder bottom and formed by a spherical-crown-shaped curved surface and an annular curved surface, and the slope becomes smaller gradually; the upper edge of the annular curved surface is tangent to the cylinder body, and the lower edge of the annular curved surface is tangent to the edge of the spherical-crown-shaped curved surface; an Archimedean screw grid formed by the anticlockwise Archimedean screw grid bars is arranged in the bottom of the curved surface cylinder; a pulverizing screen is arranged in a water inlet, and impurities in water flow which flows in from a water inlet are smashed through the pulverizing screen and then enter the pump cylinder. According to the method for rectification of the bottoms of the Archimedean screw grid bars of the integrated pump station, the structure is reasonable and simple, production and manufacturing are easy, and the method is advanced and scientific.
Description
technical field [0001] The invention relates to a water conservancy project facility, in particular to a method for rectifying the bottom of the Archimedes spiral grid bar of an integrated pumping station, and belongs to the technical fields of water conservancy project and municipal project. Background technique [0002] At present, the domestic demand for buried prefabricated pumping stations is very large. With the acceleration of the country's urbanization process and the construction of various infrastructures across the country, more and more areas of wastewater cannot flow to the discharge pipes by themselves, which requires pumps. station to lift and convey. The traditional concrete pumping station is the current mainstream pumping station construction method. Its shortcomings such as huge investment, long construction period, consuming a lot of manpower and material resources, and inability to move are becoming more and more obvious. The integrated prefabricated p...
