Embodiment Construction

[0012] Embodiment of the present invention: the comprehensive pipe ditch is connected with the upstream drainage channel (1), the upstream drainage channel (1) communicates with the front chamber of the water-sealed well (3), and the front chamber of the water-sealed well (3) is connected with the rear chamber of the water-sealed well ( 4) Separated by a water-sealed partition wall (5), the water level connection between each other is a conventional configuration; the back chamber of the water-sealed well (4) is connected with the downstream drainage pipe (2); at the lower part of the water-sealed partition wall (5) There is an overflow channel (6), and the total cross-section of the overflow is calculated and determined according to the design water volume; the overflow regulating plate (7) is set on the water-facing surface of the water-seal partition wall (5) in the front chamber (3) of the water-sealed well. The installation parts of the structural walls on both sides of th...

Abstract

This is a float-form regulate device use to regulate the section volume of flow in the watercourse. It contains: The upper reaches escape canal, lower reaches escape canal, water-proof well front room, water-proof well back room, water-proof separate wall, water course passage, and water course regulate plate. The upper reaches canal connect with the waterproof well front room, between the waterproof well front room and back room there are water-proof separated wall, on the water-proof separated wall's lower part have water course passage; on the water course regulate plate fixed air tight float-chest and regulate float.

Description

Technical field: [0001] The invention relates to an automatic adjustment device for the flow section of a gravity drainage pipe with large flow change. technical background: [0002] In the severe cold area, the project adopts the comprehensive pipe ditch to lay the pipeline. For the case where the rainwater and production wastewater are discharged in the integrated pipe ditch using the drainage ditch, the following problems must be solved at the connection between the integrated pipe ditch and the downstream drainage pipes and canals. Take measures to prevent the cold air from the outer part of the pipeline from entering the integrated pipe ditch and the integrated pipe communication gas well to form an air flow channel through the pipe channel, causing freezing damage; at the same time, try to reduce the gas flow in the outer part of the pipe channel to drain its own heat and avoid drainage pipes. It freezes. To solve the above problems, water seal wells can be used to cu...
