Embodiment Construction

[0006] The technical solution provided by the present invention is a sprayed concrete construction process, including the following steps: 1) Check the size of the excavated section, remove the scum, and clean the surface to be sprayed; 2) Mix the sprayed mixture; transport the sprayed mixture; 3) 4cm of primary sprayed concrete; 4) Apply anchor rods, steel frames, and hanging steel mesh; 5) Clean up the powder dust of the initial spraying; 6) Re-spray to the design thickness; 7) Clean up construction equipment.

[0007] The sprayed rock surface should be treated before spraying. Generally, high-pressure water can be used to wash the floating dust and cuttings on the rock face sprayed. When the rock face is easily deliquified and muddy when it encounters water, it is advisable to use high-pressure wind to blow the rock face clean. If it is a muddy or sandy rock surface, thin steel mesh should be hung (the mesh should not be larger than 20×20cm, and the wire diameter should be ...

Abstract

The invention discloses a construction process for spraying concrete. The construction process is characterized by comprising steps of 1), inspecting the sizes of excavated sections, eliminating float residues and cleaning sprayed surfaces; 2), mixing sprayed mixtures and transporting the sprayed mixtures; 3), initially spraying the concrete with the size of 4 cm; 4), applying anchor rods and steel frames and hanging reinforcement nets; 5), eliminating dust on initially sprayed surfaces; 6), repeatedly spraying the concrete until requirements on designed thicknesses are met; 7), cleaning construction machines and tools. The construction process has the advantages that the construction efficiency can be improved, large quantities of repeated working procedures can be omitted, and the labor intensity can be relieved.

Description

technical field [0001] The invention relates to a sprayed concrete construction technology. Background technique [0002] Shotcrete is a construction method of spraying and pouring fine stone concrete with a pressure spray gun. It is often used to fill tunnel linings, walls, ceilings and other thin-walled structures or linings of other structures, as well as the protective layer of steel structures. The current shotcrete construction process is complicated, with many repeated processes, and the construction process is chaotic. Not targeted. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a sprayed concrete construction process, which is simple, eliminates many repetitive procedures, and improves work efficiency. [0004] In order to achieve the above purpose, the present invention provides a sprayed concrete construction process, which is characterized in...
