Deep-well pump room for deep drainage tunnel

Abstract

The invention provides a deep well pump room for a deep drainage tunnel, and belongs to the field of urban drainage. The deep well pump room comprises a water collecting well and a pump room working area, wherein the water collecting well is rectangular, one end of the water collecting well is used for being connected with a deep drainage tunnel, and the other end of the water collecting well is connected with the pump room working area; the pump room working area is designed to be circular, a water inlet runner layer, an equipment layer and a ground layer are sequentially arranged in the pump room working area from bottom to top, one end of a water inlet main pipe in the water inlet runner layer is connected with a water collecting well, and the other end of the water inlet main pipe is connected with a water inlet runner which is connected with a lifting main pump in the equipment layer through a water pump shunting pipe, and meanwhile, the lifting main pump is connected with a water outlet channel of the ground layer through a water outlet pipe, so that rain sewage in the deep drainage tunnel is lifted and discharged. The rectangular catchment well and the large-diameter circular pump room working area are arranged in a racket shape, transition connection of the deep drainage tunnel and the deep well pump room is achieved, and the problem of multi-specialty cross interference caused by synchronous construction is avoided.

Description

technical field [0001] The invention belongs to the field of urban drainage, and more specifically relates to a deep well pump room for deep drainage tunnels. Background technique [0002] With the rapid development of the city, its requirements for the drainage capacity of the drainage system are getting higher and higher, and the shallow space on the ground surface has been occupied by various living facilities and pipelines. The existing shallow underground drainage system has problems such as complex pipelines, difficulty in expanding the drainage system, and difficulty in building a new drainage system. Moreover, the development of subways and underground complexes also leads to very limited shallow underground space. Using deep underground space to build large-scale drainage tunnels to solve drainage problems has become the choice of foreign developed cities. Deep drainage tunnels can avoid a large number of land acquisitions and demolition, avoid affecting the lives o...
