Example Embodiment

[0012] Combined with the SINO project in Western Australia, the present invention includes

[0013] (1) Cast-in-site 600mm thick culvert foundation slab

[0014] When constructing the cast-in-situ reinforced concrete bottom plate of the exit corridor, the L-shaped embedded parts connected and fixed with aluminum alloy corrugated plates are pre-embedded on the concrete foundation at the foot of the arched culvert. As all aluminum alloy corrugated plates are connected by bolts, appropriate fine adjustments can be made during installation. The installation deviation of embedded parts is required to be within ±16mm, which meets the installation accuracy requirements of aluminum alloy corrugated arched plates.

[0015] (2) Install aluminum alloy corrugated arc plate

[0016] The weight of a single piece of corrugated board is 310kg, and each corridor is installed with 84 pieces, a total of 26t, which is pre-made by the manufacturer and sent to the site. During installation, use lifting eq...

Abstract

The invention relates to construction of a concentration tank for a metallurgical mine project. A construction method for an underground outlet gallery of an assembled concentration tank of aluminum alloy corrugated plates comprises the following steps: 1, processing designated models of aluminum alloy arched corrugated plates in a factory, and transporting the corrugated plates to a site; 2, backfilling and compacting a bottom foundation of an outlet gallery bottom plate foundation, constructing the cast-in-situ concrete bottom plate foundation, and embedding arched corrugated plate embedding connectors into the bottom plate foundation; 3, assembling the aluminum alloy arched corrugated plates connected by bolts on a concrete bottom plate into an overall arched culvert structure by adopting hoisting equipment, and connecting and fixing the bottoms of the arched plates with the embedded parts of the bottom plate foundation; and 4, backfilling and compacting backfill earthworks on two sides and at the top of the arched culvert structure layer by layer. During backfilling, the two sides of the arched culvert should be stressed uniformly, to avoid deformation caused by high stress on a single side. The method can greatly shorten the construction period and reduce the cost.

Description

technical field [0001] The invention relates to the construction of a concentration pool for a metallurgical mine project, in particular to a construction method for an underground exit corridor of the concentration pool. Background technique [0002] The large thickening tank is an important equipment in metallurgical mine projects, and its structural main body generally includes three parts: bottom flow pump room, outlet corridor and thickening tank body. The exit corridor usually adopts cast-in-place reinforced concrete structure, which requires a large number of on-site construction workers to carry out reinforcement binding, formwork support, concrete pouring and maintenance. Especially for large concentration tanks, the amount of concrete work is large, the construction period is long, and the cost is relatively high. Taking the 90m-diameter floor-standing tailings thickening pond in the beneficiation area of ​​the SINO IRON iron ore project in Western Australia as an...
