Abstract
The utility model discloses a drainage pump station for underground line intervals of rail traffic. The drainage pump station is arranged in the middle of an integrated ballast bed, namely at the lowest point of a shield interval, and comprises a drainage pump and a water pumping pipe, wherein a drainage pipe opening of the drainage pump is connected with the water pumping pipe; a drainage pump body is fixed to the bottom of a water collection pit by a fixed pipe clamp; and the water collection pit is formed in a central drainage ditch, and the depth of the water collection pit is 600 millimeters. The drainage pump station has the advantages that the drainage pump station is arranged at the lowest point of the shield interval, so the drainage requirement of running tunnels is met, the safety requirement on the strength of the ballast bed during the running of trains is met, and the requirement of sewage discharge under the daily and fire-fighting working conditions also can be met; and high risks and high investment of the construction of interval connection channels are avoided effectively.
Description
Technical field
The utility model relates to a kind of drainage pumping plant; Particularly relate to a kind of interval drainage pumping plant of track traffic underground line that is suitable for.
Background technology
City track traffic engineering underground line running tunnel generally is " V " font gradient; Middle minimum point must be provided with drainage pumping plant; To get rid of the ponding in the tunnel, existing drainaging scheme is that service channel is provided with jointly between the land, and sump is arranged at minimum point between the two threaded list roads.But there is following defective in the drainaging scheme of existing city rail engineering: the firstth, and the construction risk of interval service channel and pumping plant is big, and buried depth is bigger, the engineering construction difficulty; The secondth, the freezing hidden construction process construction of domestic most employing, expense is high; The 3rd is long in time limit, controls and influence total duration of engineering.More than 3 be the enforcement difficult point that city rail engineering is generally acknowledged, once had a plurality of engineerings to cause the landslide accident because of the construction service channel.
Summary of the invention
The utility model technical problem to be solved is to provide a kind of track traffic underground line interval of satisfying shield structure running tunnel drainage requirement to use drainage pumping plant.
The technical scheme that the utility model adopted is: the interval drainage pumping plant of a kind of track traffic underground line, drainage pumping plant are arranged on the interval minimum point of middle part-shield structure of solid concrete roabed, comprise drainage pump and lifting pipe; The draining mouth of pipe of said drainage pump is connected with lifting pipe, and the drainage pump body fastens the bottom at sump through stationary pipes; Said sump is arranged in the central row ditch, and the degree of depth of sump is 600mm.
Said drainage pump comprises first drainage pump and second drainage pump; Said central row ditch is provided with along the track circuit direction, and the degree of depth in central row ditch is 480mm; Bottom and sidewall spray epoxy water-repellent paint at said sump.
Top, said central row ditch is provided with double-edged fine-toothed comb.
The output of said lifting pipe 30 is connected with elastomer connector, gate valve and flap valve in regular turn.
Also comprise being arranged on the two-layer reinforcing bar that solid concrete roabed distributes up and down between sleeper, the transverse reinforcement spacing is 200mm, and said sump bottom is provided with longitudinal reinforcement, and rebar spacing is 120mm.
The beneficial effect of the utility model is: owing in the interval minimum point of shield structure drainage pumping plant is installed, satisfy the drainage requirement of running tunnel, to the Strength Safety requirement of railway roadbed, also can satisfy the discharge of wastewater demand under daily and the fire-fighting operating mode simultaneously when reaching train operation; Effectively avoided the excessive risk of interval service channel construction and with high investment.
