Abstract

The invention discloses a treatment method of a pump pit. The treatment method of the pump pit comprises the following steps that a foundation pit is excavated; the pit is backfilled with stone for throwing stones to squeeze sludge so as to form a backfill layer, and the stone is a combination of one or more of rubble, freestone and cobble; and a retaining wall is built at the side edge of the backfill layer to form the pump pit. According to the treatment method of the pump pit, the foundation pit is backfilled with the stone for throwing the stones to squeeze the sludge, the sludge in the foundation pit is squeezed out by the stone, and the pieces of stone are mutually squeezed to squeeze the sludge out of the foundation pit range, so that the backfill layer is dense to improve the bearing capacity of the foundation pit and decrease the settlement amount, accordingly, the strength of the pump pit is improved, the stability of the pump pit foundation is ensured, and the pump pit treated through the treatment method is high in brine corrosion resisting capability, not liable to landslide, settle or collapse and long in service life; and the treatment method is rapid in construction, simple in process and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of pump pit structures, in particular to a treatment method for a pump pit used for anti-corrosion in mining areas and the pump pit. Background technique [0002] At present, the Chaerhan Salt Lake area in the Qaidam Basin is the main mining area for the production of potassium chloride and other potassium fertilizers. The salt lake area is rich in underground brine, and the water level of the underground brine is relatively high. In order to facilitate the extraction and transportation of brine, usually in Chaer A pump pit is built on the Khan Salt Lake. The pump pit is a pit for placing a pump or a pumping station, and is generally constructed on the basis of concrete. [0003] However, the soil in the Chaerhan Salt Lake area is chlorine saline soil. Saline soil is a general term for saline soil, alkaline soil and various salinized and alkalized soils. Saline soil refers to the soluble salt content in the ...
