Background technology
In tunnel double-lining concrete construction, pours the general mould that pours for using 12m long and build trolley, according to tunnel side wall height
It pours to be reserved at left and right sides of trolley when mould builds trolley in manufacture and pours skylight, per 3 layers of side, 3 every layer, totally 18 skylights,
When carrying out tunnel double-lining concreting, concrete pump is sent to the master for being mounted on and pouring mould and building trolley top platform by delivery pump
Feed bin, by main chute by the concrete conveyance in major ingredient storehouse to subordinate's feed bin, then by dividing chute will be mixed in subordinate's feed bin
Solidifying soil is transported to string bucket, finally divides sliding slot by concrete by pouring skylight under between skylight through being connected to string bucket and pouring again
Upward laminated pouring operation, left and right alternately pours between two lining templates and the hole wall just served as a contrast one by one, to complete concreting.
It is this to pour mode speed slowly and be susceptible to open roof common fault in casting process, it is poured when carrying out two lining concrete
When building construction, usually according to sequence first one task that pours for pouring skylight of completion is poured, it then can just be moved to next pour
It builds skylight and carries out pouring construction, each pour between skylight that there are construction time intervals in this way, and pour into each skylight that pours
The setting time of concrete will have that setting time is poor, the concrete that the meeting of the concrete first poured into is poured into earlier than after and coagulate
Gu therefore from when solidification of the different joining places for pouring the concrete that skylight pours into because of concrete after entire pouring construction
Between difference it is possible that fusion is bad, open roof common fault or apparent concrete watermark are easily formed after form removal, these all will
Influence final construction quality, it is also possible to the problems such as causing the tunnel double-lining poured there are safe mass hidden danger.

The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figure 1, being the feeding-distribution device of tunnel double-lining concreting provided by the utility model, the feeding-distribution device
Including feed bin 10, silo support 30 and two chutes 20, the silo support 30 is used for from described in the support of 10 bottom of the feed bin
Feed bin 10, the top of the feed bin 10 are provided with concrete feeding mouth 101, and the side wall of the feed bin 10 opens up that there are two opposite
Concrete discharge port 102, two concrete discharge ports 102 respectively with 20 seamless connection of corresponding chute, the chute 20
For will be from the concrete conveyance that the concrete discharge port 102 flows out to corresponding low-level device (such as go here and there bucket).
Wherein, the feed bin 10 is welded by plurality of steel plates, and the steel plate of welding feed bin 10 can be made using construction site
Used waste and old steel plate not only can be salvaged but also can save production cost, and the steel plate thickness for welding the feed bin 10 is 3mm
~5mm, it is preferable that the steel plate thickness is 4mm, and the material of the feed bin 10 can be steel alloy, stainless steel, tool steel, bullet
Any one in spring steel, silicon steel, in one embodiment, construction site is possible to the waste and old steel with a variety of unlike materials
Plate, such as have steel alloy steel plate and stainless-steel sheet, it, can also if one of which material not enough makes a feed bin 10
It is used as the material of a feed bin 10 using both materials simultaneously.
In order to ensure pouring quality and pour efficiency, the volume of the feed bin 10 is 0.5m3~0.8m3, in casting process
In, the volume of feed bin 10 should not be too large or too small, if 10 volume of feed bin is excessive, be easy to cause 10 inner concrete of feed bin and overflows
Go out, if volume is too small, and be easy to cause under feeding in casting process, frequently occurs and pour time interval and cause open roof
Phenomenon occurs.Opposite concrete discharge port 102 there are two being opened up on 10 side wall of the feed bin, the concrete discharge port
102 position is opened on the side wall of the side wall of feed bin 10 and the feed bin 10 of the bottom intersection of feed bin 10, contributes to expect in this way
Concrete in storehouse 10 flows out and is not easy to accumulate in the bottom of feed bin 10.
The feed bin 10 is supported by silo support 30.As shown in Figure 2, it is preferable that the silo support 30 is by more steel
Muscle is welded.According to a kind of embodiment, the silo support 30 have four equal lengths support leg and with four branch
The support ring support of support leg welding, the setting of the feed bin 10, can be by welding by feed bin 10 and feed bins on support ring support
Holder 30 is fixedly connected, and feed bin 10 can be also directly placed in support ring support according to the contour structures of feed bin 10, the feed bin
10 can be designed as the infundibulate that size from the top to the bottom is gradually reduced, this shape stream out of feed bin 10 convenient for concrete
Go out.
In order to ensure production safety, contingency is prevented, as shown in Figure 1, the feeding-distribution device further includes supporting rod
40, the feed bin 10 is reinforced for the side wall from the feed bin 10 and is supported, supporting rod 40 is installed additional in the side wall of feed bin 10 so that
Feed bin 10 is more firm safe in use.
According to a kind of embodiment, silo support 30 is formed by more reinforcement weldings, and coagulation is filled in the feed bin 10
After soil, the weight of entire feed bin 10 and concrete is very heavy, therefore in order to ensure silo support 30 by enough support strengths, weldering
The bar diameter d for connecing the silo support 30 is：20mm≤d≤28mm, if reinforcing bar is too thin, it is possible to cannot support and fill
The feed bin 10 of concrete and cause construction accident, and if reinforcing bar is too thick, and cause the unnecessary wasting of resources.
Technical solution according to the present utility model, it is preferable that the chute 20 is arc chute.The both ends of the chute 20
