混凝土喷射机选型是否合理直接影响施工进度和工程质量. 所以, 应根据工程规模正确选择喷浆机的型号和数量, 施工期长短, 以及具体建设条件.
The specific selection should be carried out according to the following principles:
(1) It is compatible with the size of the engineering quantity and the length of the construction period. If the amount of concrete is not large and the construction period is not too long, a small mobile concrete mixer can be used. If the concrete volume is large and the construction period is long, medium and large concrete jet groups (groups) should be used.
(2) Meet the requirements of the transport distance. If the conveying distance is long, the working wind pressure is low. It is suitable for dry jet machines.
(3) When the spray working face has water seepage or wet base surface, dry jet machine should be used.
(4) Meet the dust requirements. When the construction site requires high dust, wet or tidal concrete jetting machine should be used; when there is no requirement for dust, dry concrete jet can be selected.
