A frame type drainage well and its construction method

Abstract

The invention discloses a framework type drainage well and a construction method of the framework type drainage well. The framework type drainage well comprises a well base. An oil derrick is arranged at the top of the well base and comprises well columns and ring beams. Pin shaft holes are formed in the perpendicular direction of the well columns. Pin shafts are inserted in the pin shaft holes. The ring beams are arranged between the adjacent well columns. Annular baffles are perpendicularly overlapped and installed in the internal space defined by the well columns and the ring beams. The annular baffles are cylindrical. The inner wall of each annular baffle is provided with a lifting lug. The outer wall of each annular baffle is in fit with the inner walls of the well columns and the inner walls of the ring beams. The annular baffles are supported by the pin shafts of the same height. An annular supporting platform is arranged at the top end of the well base. A drainage channel is formed between the bottom end of the annular baffle at the bottommost end and the supporting platform. The construction method includes the steps of excavating a well base foundation, manufacturing the well base and the well columns, manufacturing the annular baffles, overlapping the annular baffles, inserting the pin shafts into the holes and lifting the annular baffles. The later operation is convenient and rapid, time and labor are saved, and the framework type drainage well is safe, reliable, good in integration, firm and durable.

Description

technical field [0001] The invention relates to a drainage well and a construction method thereof, in particular to a mine tailings frame-type drainage well and a construction method thereof. Background technique [0002] Drainage wells are one of the important structures of mine tailings facilities. Most of the rain, snow and tailings clarification water that falls in the catchment area of ​​the tailings pond pass through it, and then are discharged out of the pond through structures such as drainage culverts or tunnels to ensure that the tailings dam will not be flooded and the tailings will be clarified. Return to the concentrator for reuse. [0003] At present, the commonly used drainage wells in China include window drainage wells, semicircular baffle (double-column) drainage wells, frame baffle drainage wells, block drainage wells and well ring stacked drainage wells. The window-type drainage well is built at one time, and there are round or square windows at differe...
