Description
Technical field
The utility model relates to the metro station construction field, is specially rail air channel, a kind of subway station.
Background technology
Tread air channel, subway station is to get rid of heat that the air conditioner of subway vehicle system distributes, satisfy passenger's constructional device that comfortable institute must setting of riding, and adopts the two kinds of methods in iron sheet airduct and steel concrete air channel usually.Though iron sheet air channel construction is simple, there are shortcomings such as antirust, anticorrosion in it, and there is potential threat in traffic safety; The steel concrete air channel is durable in use, and helps eliminating the noise, and in subway station design at present, adopts more.When construct in the air channel of employing concrete structure form; Conventional way is below middle template die frame system, to build the tread air channel earlier before the middle plate construction; Reserve and middle plate anchor bar; Air channel intensity satisfies after the construction intensity requirement in the air channel formwork and builds middle plate, and construction period is longer, need be with the air channel separately as the operation of a flowing water section.A kind of in addition conventional way is for building middle plate earlier; Reserve the air channel anchor bar in middle plate bottom, middle plate scaffold is removed the back employing and is hung method constructing and overhanging model tread air channel, and this method need be carried out work high above the ground; Construction danger is bigger; And need carry out the internal mold external mold and reinforce, construction technology is complicated, and the quality control on construction difficulty is big.
Summary of the invention
When the utility model adopts iron sheet airduct and steel concrete air channel to construct in order to solve existing tread air channel, subway station; Have long construction period, construction is dangerous big, construction technology is complicated; Problems such as the quality control on construction difficulty is big provide tread air channel, a kind of subway station.
The utility model is to adopt following technical scheme to realize: tread air channel, subway station, said tread air channel is made up of the mutual assembly unit in unit, the prefabricated air channel of the concrete prefabricated plurality of sections that forms.
Unit, described contiguous prefabricated air channel is to connect through bell and spigot, and is simple in structure, connect reliably, uses neoprene latex cement filleting simultaneously, can guarantee the sealing in air channel.
Adopt the structure design of the utility model, as an independent member, adopt concrete to carry out prefabricate tread air channel in the tread air channel; Process unit, the prefabricated air channel of plurality of sections earlier, maintenance is after design strength, in treating at the bottom of timbering to the air channel behind the absolute altitude; Unit, the prefabricated air channel of segmental hoisting reinforces in place; Take template die plate in the installation of full hall scaffold in inside, air channel, adopt the tread air channel of this form of structure to construct, have the following advantages:
1, centering plate construction infection is little, and construction precision is controlled easily, improves construction quality greatly;
2, avoid conversion station effective durations of agent structure such as construction of tread air channel and air channel, shortened construction period greatly;
3, prefabricated tread air channel installation has avoided hanging the mould work high above the ground, and safety factor is higher;
4, technology is simple, and unit, prefabricated air channel adopts the combined steel factory operation, and construction quality is controlled, and built-in fitting installation and reserving hole stay to be established simply, and prefabricated air channel has advantages such as high accuracy, high uniformity, high production rate.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of unit, the said prefabricated air channel of the utility model;
Fig. 3 is the mounting structure sketch map of the utility model;
Among the figure: unit, the prefabricated air channel of 1-; The 2-bell and spigot; Plate in the 3-station; 4-station side wall; 5-tread air channel.
The specific embodiment
Tread air channel, subway station, said tread air channel is made up of the 1 mutual assembly unit of unit, the prefabricated air channel of the concrete prefabricated plurality of sections that forms, and unit, contiguous prefabricated air channel 1 is to connect through bell and spigot 2.
Prefabricated air channel element length mainly consider to avoid as far as possible built-in fitting installation site and reserving hole the position is set, and the convenience of construction operation, general section length 1.5～2m, and every section numbered.During making; At first require to carry out reinforcing bar binding according to design drawing; Before installing, installation mold, template to confirm the accuracy that quantity and position are set of built-in fitting and reserving hole, after the reinforcing bar binding completion; The topping locator is installed on the master's muscle of air channel, and the control protective layer thickness is in the designing requirement scope.During matched moulds, the medial and lateral template is installed earlier, installs and reserve anchor rib position bamboo offset plate, bolt can carry out concreting after tightening and reinforce completion.Control concreting speed is divided and is built completion three times, vibrates in blanking limit, limit, and the surface is not emitting bubble, bleeding occurs and gets final product.After concreting finishes, receive light to the concrete exposed surface and handle, wipe off with nose bar earlier and remove unnecessary concrete or fill up recess, with trowel rubbing and pressure flat surface repeatedly.
During concrete the construction, can lift the air channel after the full hall of central plate scaffold building is accomplished, lift piecemeal according to the air channel numbering; Every section prefabricated air channel unit weight is 2.7～3.6T, and lifting can be adopted mobile crane or straddle truck, with the neoprene latex cement air channel inwall seam crossing is carried out shutoff behind the hoisted in position of air channel and handles; Realized the prefabricated construction in tread air channel, subway station; Reduce construction period, technology is simple, avoids work high above the ground; Safety factor is high, can guarantee the construction quality in tread air channel simultaneously.Performance analysis sees the following form:
| Performance analysis | Cast-in-place method | Hang modulus method | Prefabrication |
| Direct economic benefit | 720,000 | 1,240,000 | 740,000 |
| Society's (duration) benefit | Each construction section need take 10 days durations, and total duration increases by 60 days | Influence the station secondary structure, dynamo-electric install, decorations 40 days. | Do not influence the construction of structure flowing water section, do not take total duration. |
| The safe mass benefit | Template is installed strengthening quality require height, concrete apparent mass control difficulty is big in the construction. | Work high above the ground, security risk is big, and interior external mold strengthening quality control difficulty is big. | Technology is simple, and control construction quality is avoided work high above the ground easily. |
Adopt the prefabricated tread air channel of the utility model to construct, can practice thrift 40 day duration at least than conventional job practices, reduce project operation cost 1,200,000, economic benefit and social benefit effect are remarkable.
