Material mouth connection.
Preferably, the discharge outlet of longitudinal diversion pipe is provided with shut-off valve.
Preferably, the discharge port of longitudinal isocon is provided with the gate spool that puts in storage；Meanwhile it being additionally provided on longitudinal isocon vertical
To flow divider.
Compared with prior art, the utility model has the beneficial effects that
Balance cloth part flow arrangement provided by the utility model for the casting of tunnel double-lining concrete, by the cross of concrete
Stringent differentiation has been carried out with longitudinal diverter function to shunting, multiple equilibrium cloth is realized in tunnel double-lining concrete placement
The gravity flow of material is put in storage, and the problem of the offset and concrete uniformity difference of trolley caused by single-point cloth is overcome, and is that tunnel double-lining is fast
Speed construction creates condition, and compared with prior art, it is excellent to have that easy for construction, quality controllable, labor intensity is low, work efficiency is high etc.
Point is suitable for the constructing tunnels occasions such as railway, highway, subway, has application value.
Further, pump concrete is accepted using lateral diverter feed bin single-point, and to the uniform multiple spot of longitudinal current divider
Concrete is distributed, disposable the lateral of concrete of completing shunts, and reduces height loss, is that longitudinally item is created in distribution to concrete
Part.
Further, concrete is accepted using longitudinal current divider splicing groove, and by several times to each casting window of different height
Mouth distribution concrete realizes that gravity flow balance is poured into storehouse；
Further, the harmony laterally shunted using lateral flow divider control concrete；
Further, the uniformity that each casting window concrete enters mould speed is controlled using longitudinal flow divider；
Further, longitudinal current divider is vertically connected using flange, realizes that layering is successively poured；
Further, the layer position of shut-off valve control concrete casting is utilized.
