Abstract

The invention discloses a conveying system and method capable of adjusting the blanking speed at a constant speed for steel shell concrete. The system comprises a pouring trolley frame, a hopper and aconstant-speed blanking system, the hopper is fixed on the pouring trolley frame, and the constant-speed blanking system is connected with a hopper discharge port. The constant-speed blanking systemis composed of a blanking valve, a gear blanking device, a speed reduction frequency converter, a lead screw lifter and two motors, the inner structure of the blanking valve comprises a blanking baffle and a driving shaft, one motor is arranged at the top end of the lead screw lifter, the lead screw lifter is hinged to a driving shaft, and the driving shaft is connected with the blanking baffle. By means of the system and method, the defects that a concrete surface layer is uneven and air is difficult to remove in a later period of pouring are overcome. And the working efficiency and the capacity are improved, the production cost is reduced, the construction qualification rate is improved, local cavities, large-area air holes and honeycomb pitted surfaces of a steel shell and the concretesurface layer are prevented from being generated during pouring, and the engineering quality is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of civil engineering equipment, in particular to a steel-shell concrete conveying system and method capable of adjusting the feeding speed at a constant speed. Background technique [0002] The Shenzhong Channel is a strategic cross-river channel connecting the two sides of the Pearl River. It is a cluster project integrating the "four-in-one" super-wide submarine tunnel, super-long-span bridge, deep-water artificial island, and underwater intercommunication. It has an unprecedented scale and extremely complex construction conditions. The technical difficulty has reached a new high, and it is another world-class major cross-sea transportation project in my country after the Hong Kong-Zhuhai-Macao Bridge. [0003] The deep-middle channel will adopt a "sandwich" structure steel shell concrete immersed tube (hereinafter referred to as steel shell concrete immersed tube), with a total length of 5035m, which is pl...
