A screening slag loading building

Abstract

The invention discloses a screening slag loading building, comprising a vibration vibrating screen, an aggregate box, a slag collecting box, a first slag separator and a second slag separator; the aggregate outlet of the vibration vibrating screen is connected with the aggregate box; a waste slag outlet of the vibration vibrating screen is connected with the charging port of the first slag separator; the first slag separator comprises a first slag separation drum connected with the slag collecting box and a second slag separation drum connected with the charging port of the second slag separator; the second slag separator comprises a third slag separation drum and a fourth slag separation drum which are used for loading materials to a transfer vehicle; a switching device for controlling the flow direction of waste slag is arranged in each of the first slag separator and the second slag separator. The screening slag loading building effectively realizes the seamless jointing for transferring the waste slag and aggregate, so the transferring efficiency of the waste slag and the aggregate is improved, and the aggregate in the slag material can be used and taken on site and used as the sand aggregate for lining a channel.

Description

technical field [0001] The invention relates to the technical field of slag material transfer in tunnel construction, in particular to a screening slag loading building. Background technique [0002] When the TBM method is used for tunnel construction, long-distance tunnel slag discharge is one of the main factors restricting the total project duration. Due to the limited space, the slag transported by the belt conveyor to the outside of the cave must be efficiently reversed. The slag is directly transported to the entrance of the cave through the belt conveyor, and a lot of construction equipment needs to be invested in the secondary transport, which is costly and inefficient. [0003] At present, a slag separator is adopted in the prior art, which loads the slag material onto the transfer vehicle through the main slag separator and the sub-slag separator. However, in the actual use process, when the transfer vehicle breaks down or cannot be put in place, the slag can only...

AI Technical Summary

Problems solved by technology

However, in the actual use process, when the transfer vehicle breaks down or cannot be put in place, the slag can only be unloaded on the ground, and a second dumping is required, which has not fundamentally overcome the problem of dumping the slag

In addition, the tunnel lining is a reinforced concrete structure with high quality requirements and a large demand for sand and gravel aggregates. It is difficult to meet the requirements in terms of quantity and quality of locally purchased aggregates, and considering economic issues, it is necessary to make full use of TBM excavation slag for aggregate production. Screening and processing

This kind of slag separator directly separates and transports the slag, and cannot screen the aggregate in the slag
