Tunnel slag tapping, sand and gravel processing and concrete processing and conveying integrated equipment and process

Abstract

The invention discloses a tunnel slag tapping, sand and gravel processing and concrete processing and conveying integrated equipment and process. The tunnel slag tapping, sand and gravel processing and concrete processing and conveying integrated equipment comprises mobile crushing equipment, wherein a discharging port of the mobile crushing equipment is sequentially connected with a material pre-sorting system, an aggregate processing system and a concrete processing system through a telescopic conveying belt group, and a discharging port of the concrete processing system is connected with aconcrete belt conveying system; after materials in a tunnel blasting area B are preliminarily crushed by the moving crushing equipment, the materials are transported into the pre-sorting system and the aggregate processing system to prepare fine aggregates and fine sand with different gradations, finally transported into the concrete processing system to prepare concrete, and transported to a tunnel construction area through the concrete belt conveying system for concrete construction after penetrating through a lining trolley. The manpower and material resources are reasonably utilized and distributed, the automatic construction of a tunnel is achieved, high flexibility and good safety performance are achieved, and the construction efficiency and quality of the tunnel are greatly improved.

Description

technical field [0001] The invention discloses an integrated equipment and technology for tunnel slag discharge, sand and gravel processing, and concrete processing and transportation, which belong to tunnel construction, tunnel slag transportation, tunnel concrete transportation, long-distance retractable belt, sand and gravel aggregate sorting and sand and gravel Aggregate processing technology field. Background technique [0002] Tunnel construction is a world-class problem. [0003] At present, the commonly used tunnel construction methods include TBM, shield machine, mining method and other technological methods; among them, TMB is mainly used for hard rock tunnel excavation, while shield machine is used for soil tunnel excavation; these two construction methods have high cost and maintenance Difficulties, the equipment can only move forward but not backward, and the implementation of the construction method is limited by rocks. The mine processing method is relativel...

Problems solved by technology

[0003] At present, the commonly used tunnel construction methods include TBM, shield machine, mining method and other technological methods; among them, TMB is mainly used for hard rock tunnel excavation, while shield machine is used for soil tunnel excavation; these two construction methods have high cost and maintenance Difficulties, the equipment can only move forward but not backward, and the implementation of the construction method is limited by rocks, etc.

The mine processing method is relatively simple, and there are more mature Norwegian methods and new Austrian methods from the face to the construction; the transportation of materials is usually carried by rail battery vehicles; its advantages are simple and flexible, but its disadvantages are also very Obviously; there are a large number of construction personnel, and they are interspersed with each other. The safety production problems caused by this are very prominent, the ventilation cost is high, and the transportation energy consumption is high, especially in the alpine plateau area. The impact of construction is more obvious; The construction of medium concrete and the transportation of slag are carried out simultaneously. Tunnel construction usually has a tight schedule, and there is no time to wait for the concrete to be cured for 28 days. Vehicles must start rolling after two or three days. Repeated rolling of road transport vehicles cannot guarantee the normal maintenance of concrete. Cause the inverted arch to be crushed, leaving permanent damage and defects to the tunnel; it is difficult to guarantee the quality of the project
