Description
Technical field
The utility model technology is related to urban rail transit elevated station construction technical field, is particularly suitable for use in and is runing
The situation of overhead station is built on railroad section.The protecting platform car that the utility model technology is used is that one kind can effectively ensure that
Station construction safety, the measure for improving efficiency of construction.
Background technology
With the urbanization of modern metropolitan cities surrounding area and continuing to develop for Construction of Urban Rail Traffic, the fast of city is covered
Fast traffic system gradually extends to suburbs, with the underground station by factor controllings such as downtown surface structures, road network, construction costs
Compare, the advantage of elevated station is clearly：Construction cost is low, and construction speed is fast, broad view, and passenger's perception is good, comfort level is good,
Fire-fighting and rescue condition is good during accident, without ventilating system, and air-conditioning and lighting energy consumption are small, run energy consumption greatlys save.Therefore,
As urban transportation is improved, City Green, low-carbon, the accessory substance of the effective measures of sustainable development, urban track traffic are promoted
The planning and design of elevated station are got growing concern for.
In subway line process of construction, part overhead station is present because planning reason wouldn't construct, and erect-position is reserved, and treats it
Surrounding enviroment reach situation about implementing again after planning requirement.In these reserved overhead stations, with the middle of existing operating line
The situation for setting up station is the most complicated.Because operation has been put into the railroad section opened in advance, the station such as set up is not taken
Corresponding safeguard measure, the then waste and debris that construction period produces may fall into and run interval, so as to have influence on train
Normal operation even threaten the personal safety of passenger.On the other hand, the interval safeguard measure of operating line is belonged to and faced
When measure, its protectiving scheme should match with setting up the form and scale at station, on the premise of subway traffic safety is ensured, to the greatest extent
Amount reduction investment, and reduce the influence to setting up station construction.Therefore, overhead station is set up on the existing operation line of subway, it is right
Design and construction requirement are higher, and its construction safeguard measure and scheme need to suit measures to local conditions, with reference to on-site actual situations and surrounding enviroment
Consider, on the premise of traffic safety is ensured, take into account station construction progress and quality.
In the case where not using the utility model technology, due to the no any resistance in construction working face and circuit rail row interval
Gear and barrier, building materials and equipment very likely fall into Gui Hang areas in construction period, so as to cause potential risks and potential safety hazard；
On the other hand, to avoid influencing each other between station construction and train operation, unit in charge of construction must treat that overnight train is stopped transport and overhaul
Shi Fangke marches into the arena construction, and must catch up with and withdrawn at second day before railroad embankment, and the engineering time is short, and job placement is difficult, cost compared with
It is high.
The content of the invention
The purpose of this utility model is to provide a kind of subway overhead station construction protecting platform car.The letter of the utility model structure
Single, workable, reliability is high, and efficiency of construction is higher, and structure stress clearly, and can realize that train operation and station construction are same
Shi Jinhang, between be independent of each other, fully ensure train operation safety and station construction efficiency.
The purpose of the utility model technology is to be achieved by the following technical programs：Subway overhead vehicle of the present utility model
Stand construction protecting platform car, include platform car crossbeam, two platform stays, platform truck diagonal brace, platform pulley sheave, platform trucks
Track girder, platform slab track built-in fitting, underground railway track both sides are equipped with platform slab track built-in fitting or are equiped with two interim branch
Support column, two platform truck upright supports on platform slab built-in fitting or temporary support column, platform car crossbeam and both sides it is flat
Chassis column is connected, and platform truck diagonal brace is provided between platform car crossbeam and platform stay and is supported reinforcing
The utility model technology has the advantages that：
（1）Protecting platform is simple in construction, workable, and reliability is high, and main member is prefabricated in factory, then transports
To building site assembly, welding and lifting, efficiency of construction is higher, and speed of application can be completed up to 3 ~ 4 Pin/day within the most short time
Whole protecting platform construction.
（2）Protecting platform uses steel structure system, and structure stress is clear and definite, load bang path is clear, structural bearing capacity height,
Rigidity is big, and station construction efficiency and the safety of train operation can be taken into account simultaneously, facilitates on-site hoisting.
（3）Protecting platform by station construction working face and circuit rail row separate from, it is ensured that train operation and station construction are same
Shi Jinhang, between be independent of each other, because day and night can construct, therefore can effectively shorten the construction period.
（4）It is advantageously implemented saving, green, the engineering concept of environmental protection.The steel structure system that protecting platform is used is AT STATION
Construction can be dismantled after finishing, and can reduce the use of construction material repeatedly using simultaneously final recyclable.
In order to reduce the risk brought during the newly-built station on operating line and improve station construction efficiency.By adopting
With stress clearly, load bang path clearly protecting platform structure, by station construction working face and circuit rail row separate from, with
Realize that train operation and station construction are carried out simultaneously, between be independent of each other, fully ensure train operation safety and station construction effect
Rate.
