Description
[technical field]
The utility model relates to subway underground structure technical field, a kind of specifically subway tunnel ditch and railway roadbed primary concreting formwork structure.
[background technology]
Construction is accomplished in general railway roadbed of the domestic job practices of taking at present and ditch fluid concrete at twice.But the product of constructing like this, the water capacity in the ditch are prone to get into railway roadbed through the constuction joint of ditch and twice cast of railway roadbed, and railway roadbed is produced destruction, and be loosening to cause the railway roadbed concrete, directly has influence on the stable of subway line, for metro operation has brought potential safety hazard.
[summary of the invention]
The purpose of the utility model is to reduce concrete to run, leak phenomenon, avoids secondary pollution, provides a kind of rational in infrastructure, is convenient to the subway tunnel ditch and the railway roadbed primary concreting formwork structure of installing/dismounting.
For realizing that above-mentioned purpose designs a kind of subway tunnel ditch and railway roadbed primary concreting formwork structure; Comprise rail, transfer the rail support, rail is fixed through accent rail support after adjusting to standard state, it is characterized in that outer respectively several the semicircle ditch templates that hangs with in the rail left and right sides; The ditch template is provided with two shanks of bolt that firmly are connected with the ditch template; Described shank of bolt top connecting angle cross-arm, the described angle steel cross-arm other end is connected with the T type bolt of rail fastening, on nearly rail side angle steel cross-arm, is provided with the chute of scalable ditch template elongation; Also be provided with on the described cross-arm and heighten bolt, the bottom support point of heightening bolt is located at the sleeper end face.
Adopt U type card connection between the template of described ditch.
Described ditch template bottom shape can be designed to small semicircle or rectangle according to field condition.
The utility model is compared with prior art,
1, the ditch template choose making, technology is simple, material is light and handy, usage space is little, is convenient to installing/dismounting in the tunnel.
2, the ditch template is fixed on the fastener of the section of track, and stability is strong.
3, behind solid concrete roabed and the ditch concrete primary concreting, few race, stripping pattern phenomenon of occurring, the ditch is linear attractive in appearance neat.
4, avoided secondary pollution to railway roadbed.
5, railway roadbed and ditch once-cast concrete, people ditch and railway roadbed become a monolithic concrete member, and the water in the ditch just can not infiltrate railway roadbed, and railway roadbed is played destruction, thereby has improved workmanship, for train operation provides safety guarantee.
6, use amount and dismounting, the number of turnover of template have been practiced thrift; Reduced the cleaning work of the cement paste that produces in the work progress.The better economic result.
7, the duration has been practiced thrift in disposal pouring railway roadbed and ditch.
[description of drawings]
Fig. 1 ditch template and railway roadbed set up floor map
Fig. 2 ditch template and railway roadbed set up cross-sectional drawing;
Fig. 3 ditch template and railway roadbed section detail drawing;
Among the figure: 1.U type card 2. ditch templates 3. angle steel cross-arms 4. sleepers 5. are transferred rail support 6. chutes 7. to be fixedly connected shank of bolt 8. and are heightened bolt.
[specific embodiment]
In conjunction with accompanying drawing the utility model is further specified, the manufacturing technology of this device is very clearly concerning this professional people.
The location of ditch template: the center, railway roadbed ditch of underground solid concrete roabed and track circuit distance are definite value, so the method for attachment of template and fastener is proper, just can control the direction in ditch.Ditch absolute altitude and tread absolute altitude relative value are certain, have also confirmed the height in ditch accordingly.
Principle:, make light and handy firm and durable for conveniently transporting and set up the most handy certain thick iron sheet at first according to the good semicircle of apparatus processing (or smaller part garden, rectangle) shape ditch template (about twice sleeper pitch is long).The tread discrepancy in elevation according to ditch and underground railway track; Two bolts that firmly are connected with the ditch template are set, and the angle steel cross-arm through certain-length, thickness is connected with the T type bolt of rail fastening, the chute of the scalable ditch template elongation that on nearly rail side angle steel cross-arm, is provided with; Heightening bolt with a certain distance from the chute setting; Be convenient to control the height of ditch template, chute with heighten bolt and will be provided with flexibly, be convenient to adjusting.
The bolt that the ditch template firmly connects through template, angle steel cross-arm, be provided with heighten bolt and adjust to the right place after, connect through the T type bolt on the rail and to be fixed on the rail.
Rail is fixed through transferring the rail support.
Between the template of ditch with iron " U " type card connection.
Template angle steel cross-arm spacing, template length all be with sleeper pitch as modulus, convenient construction location and avoided the position conflict.
Railway roadbed and ditch once-cast concrete make ditch and railway roadbed become a monolithic concrete member, and the water in the ditch just can not infiltrate railway roadbed, railway roadbed is played a protective role, for train operation provides safety guarantee.The method is applicable to urban track traffic concrete integral construction, is specially adapted to the engineering that the scope of operation is little, construction environment is complicated, the duration is tight, and can guarantee workmanship.
