Roughening device with spraying unit

Abstract

The invention provides a roughening device with a spraying unit. The roughening device comprises a connecting frame, and a spraying unit and a roughening unit which are arranged on the connecting frame. According to the roughening device, after the spraying unit communicates with a concrete pouring device, concrete pouring construction can be achieved, and meanwhile, the roughening unit can immediately conduct roughening treatment after concrete initial spraying pouring of the spraying unit, so that shoveling of over-sprayed concrete is achieved, the problem that the concrete is difficult to shovel after hardening due to untimely roughening is avoided, and the construction is convenient; and in addition, the roughening unit is fixedly connected with the spraying unit, and the roughening unit can conduct construction along with the spraying unit, so that the problems that at prior art, manual shoveling and a handheld roughening machine are difficult to cover the whole construction surface and large in labor consumption and roughening construction of an machine-mounted roughening machine is inconvenient to conduct and insufficient in construction space are effectively solved, the labor intensity of workers is greatly reduced, the construction efficiency is improved, and the construction is safe and reliable.

Description

technical field [0001] The present invention relates to a chiseling device, in particular to a chiseling device with a spray unit. Background technique [0002] In the process of concrete spraying, it is inevitable that concrete overspraying will occur in some places, which will affect the subsequent construction processes such as waterproofing board laying and secondary lining construction. It is usually necessary to immediately remove the overspray and the residual concrete on the arch frame manually or with the aid of a chisel machine. The traditional chiseling treatment on the concrete surface is done manually by on-site workers, which has a large workload and low efficiency, and the chisel quality is uneven, making it difficult to meet the engineering quality requirements; at present, some construction sites sometimes use chisel machines to achieve concrete removal. Some chisels include hand-held chisels and airborne chisels. Hand-held chisels are difficult to cover th...

The traditional chiseling treatment on the concrete surface is done manually by on-site workers, which has a large workload and low efficiency, and the chisel quality is uneven, making it difficult to meet the engineering quality requirements; at present, some construction sites sometimes use chisel machines to achieve concrete removal. Some chisels include hand-held chisels and airborne chisels. Hand-held chisels are difficult to cover the entire tunnel lining surface and consume a lot of manpower; airborne chisels usually use special trusses to support the chisel. Although the chisel machine can chisel the working surface at any angle, its structure is complex and is easily affected by the construction space; at the same time, the existing chisel machine can only realize its chisel function, and does not have the synchronization of concrete spraying construction. function, there is a problem that chiseling is not immediate and it is difficult to remove after the concrete hardens
