Description
Technical field
The present invention relates to Shield Construction Method Used field, be specially a kind of shield driving and combine light-duty sleeper safely and fast.
Background technology
China's shield tunnel starts to long distance, little curve evolution, during shield driving, shield machine and construction haulage vehicle all need sleeper, tradition sleeper with pressing plate, rail is fixed on i iron, connect with pull bar between two one steel rails, to ensure track space, because driving distance is long, curve is little, i iron dislocation is serious, pressing plate and pull bar often loosen, rail is caused often to be shifted, after finally making shield machine, supporting roller and wheel-track type locomotive fall rail, special messenger is needed to carry out maintenance, not only shield driving potential safety hazard is large, construction cost is high, and effort is installed, maintain time-consuming in operation, rear bolt corrosion of having constructed is removed and is taken a lot of work, and major part needs to use destructiveness to cut off, cannot reuse, this is a shield driving urgent problem.
Summary of the invention
The present invention falling rail to solve in existing sleeper installation effort, operation, maintaining the difficult problems such as time-consuming, the rear dismounting of construction is taken a lot of work, and provides a kind of shield driving to combine light-duty sleeper safely and fast.
The present invention adopts following technical scheme to realize: light-duty sleeper is combined in shield driving safely and fast, comprise along the laying of interval, tunnel piercing direction, be positioned at the transport vehicle channel-section steel sleeper in centre position, tunnel bottom section of jurisdiction and shield driving sleeper assembled with transport vehicle channel-section steel sleeper two ends respectively, U-type groove is all offered in same position in adjacent transport vehicle channel-section steel sleeper two ends, places transport vehicle track respectively in the U-type groove of each transport vehicle channel-section steel sleeper both sides; Shield driving sleeper comprises to fit with tunnel bottom section of jurisdiction and the identical curved plate of radian and be fixed on the arc-shaped step sleeper at the high-end place of curved plate, curved plate lower end is provided with the protuberance with the grafting of transport vehicle channel-section steel sleeper, arc-shaped step sleeper is arranged the card rail groove formed by the card rail location-plate that two positions are relative, in the card rail groove on each shield driving sleeper, place shield driving track.
In the middle part of described transport vehicle channel-section steel sleeper, lower end is fixed with the junction plate in strap bolt hole, and available bolt plate is fixed on tunnel bottom section of jurisdiction, has stopped shield driving and transported battery truck not fall rail, ensure that construction safety.
Described transport vehicle channel-section steel sleeper two ends and be positioned at U-type groove place and curved plate rounding off, ensure that transport vehicle channel-section steel sleeper and curved plate are all well fitted with tunnel bottom section of jurisdiction, guarantee reliably connects between the two.
Adopt structure design of the present invention, first adopt 100# channel-section steel to do haulage vehicle sleeper, be placed on by rail in the groove of channel-section steel two ends well cutting, channel-section steel two coxostermum just in time plays the effect of clip rail; Then use steel plate processing belt radian steel plate, curved plate is fixed arc-shaped step sleeper, the protuberance of curved plate is inserted on channel-section steel sleeper, and channel-section steel two coxostermum just in time plays the effect of clip curved plate.The last junction plate welded in the middle part of channel-section steel with bolt hole, and be fixed on segment bolt at the bottom of tunnel.Not only realize convenient and flexible installation, ensure shield driving and haulage vehicle security of operation, and realize intact fast dismantling and remove.
Compared with prior art, shield driving combine safely and fast light-duty sleeper invention have the following advantages:
1) in the U-type groove of channel-section steel two ends well cutting, install transport vehicle rail, not only reduce pressing plate and junction plate, and reduce operating maintenance maintenance;
2) insert arc-shaped step shield driving sleeper at channel-section steel two ends, not only realize peace and tear open flexibly and easily, and realize shield driving sleeper turnover use, reduce construction cost;
3) be connected on segment bolt at the bottom of tunnel with bolt weld the junction plate with bolt hole in the middle part of channel-section steel after, stopped shield driving and transported battery truck not fall rail, ensure that construction safety;
In a word, the present invention makes full use of the advantage of thin-wall channel, self U-type groove and plug-in type arc-shaped step shield driving sleeper, not only reduces special messenger and maintains track, decrease the impact of rail on shield driving, ensure that construction safety.And achieve by tearing open conveniently, improve shield driving work efficiency, reduce construction cost.Have that technique is simple, advanced technology, the advantage such as practical.
Adopt this technology to have successfully completed Shenyang Metro No. 9 lines 7 and mark the interval 4400m driving of shield structure, filled up the blank of China's shield driving composite sleeper technology safely and fast, achieved good economic benefit and social benefit.The present invention is applicable to all shield tunnels driving sleeper.
