The utility model relates to the field of foundation pit drainage, specifically relates to a foundation pit drainage
system, including drain
pipe, set up in the periphery of foundation pit, by a plurality of
pipe sections detachable connection is formed,
precipitation well, along the periphery of foundation pit interval sets up a plurality, is equipped with
precipitation water pump and is connected to drain
pipe through first connecting
water pipe, water collecting pit, set up in the foundation pit, and are connected to drain pipe through second connecting
water pipe. Through setting up drain pipe and
precipitation well realizes pit outer pipe well precipitation, realizes pit inner open drainage through setting up water collecting pit, adopts the form that both are combined, can realize the efficient drainage of foundation pit. Through connecting water collecting pit to drain pipe through second connecting
water pipe, the quick
discharge of
sewage in water collecting pit is convenient. Through setting up drain pipe as by a plurality of pipe sections detachable connection is formed, can be reused after the completion of
engineering, reduces construction cost, and need not on -the -spot excavation
drainage ditch, only needs on -the -spot in the on -the -spot assembling pipe section can realize the quick laying of drain pipe, has greatly shortened construction period.
