The specific embodiment
The principle of this end head formwork design is as shown in Fig. 1-Fig. 6, calibrated bolck 1 is provided with locator slide 4, the length of described calibrated bolck 1 and width can be adjusted according to Tunnel Second Lining thickness, on locator slide 4, connect hanger bar, hanger bar 5 can make calibrated bolck fix, dead bolt 3 is made up of oil pressure a thousand pieces of gold top 7, pressure-bearing steel plate 8 and propulsion arm 6, hydraulic jack 7 is provided with multiple, every two hydraulic jacks 7 connect by pressure-bearing steel plate 8, wherein, the length of pressure-bearing steel plate 8 can be determined according to bearing pressure size, and then the quantity of definite hydraulic jack 7.Gap between pressure-bearing steel plate 8 and secondary lining termination steel plate 9 can be obtained and be controlled by the piston rod movement on oil pressure a thousand pieces of gold top 7.Hanger bar 5 is connected with propulsion arm 6, and hydraulic jack 7 one end are connected with secondary lining chassis termination steel plate 9, and the oil hydraulic system on oil pressure a thousand pieces of gold top 7 is connected with the oil hydraulic system on secondary lining chassis, and adjustment block 2 need specifically be made according to void size in work progress.
The skin of waterstop 10 has waterproofing course 13.
Sawtooth is triangle sawtooth.
Brake bar 14 is vertical connects hanger bar 5, and between hanger bar 5 for being rotationally connected.
Erection stage, unit in charge of construction can be according to the quantity of required calibrated bolck 1 and the quantity of hydraulic jack under profile radius primary Calculation in tunnel, when concrete 12 is built, the pressure of arch crown part is little, the interval design of hydraulic jack can suitably strengthen, abutment wall site pressure is large, and the interval of hydraulic jack can suitably reduce.First should be according to the position of determining that hydraulic jack is marked in interval on the steel plate of secondary lining chassis termination, the line of the center on oil pressure a thousand pieces of gold top 7 should be parallel with tunnel inner outline.Then hydraulic jack 7 bases are welded on the position of having demarcated, then pressure-bearing steel plate 8 are soldered on the fore-set of hydraulic jack.Then the hanger bar of calibrated bolck 1 is connected with the propulsion arm on pressure-bearing steel plate 8, and propulsion arm 6 is soldered on pressure-bearing steel plate 8, one end of calibrated bolck 1 is put into the space of pressure-bearing steel plate 8 and secondary lining chassis termination steel plate 9, installation work has just completed.When use, secondary lining chassis is carried out to assigned address, from a side wall in tunnel, a mobile calibrated bolck pushes up to waterstop 10 its one end, depress hanger bar 5, fixed standard piece 1, then mobile another calibrated bolck 1 makes it be close to previous calibrated bolck fixing, successively fixed standard piece 1 until all calibrated bolcks fixedly complete, then make adjustment block 2 with plank, according to the size of each jack position shortcoming template, according to its size, plank is cut and is embedded in corresponding position, then shrink hydraulic jack 7, oil pressure a thousand pieces of gold top 7 pressure that provide make calibrated bolck 1 and the adjustment block cannot mobile fixing compact, propulsion arm makes it press closer waterstop to hanger bar to the power of waterstop direction simultaneously, formwork work completes, can concreting.In the time of detachable template, extend hydraulic jack and make pressure-bearing steel plate disengage calibrated bolck, hammering, vibrations calibrated bolck make it depart from concrete 12, remove adjustment block.This device is forever connected on lining trolley, need not manually transport.
The specific embodiment of the present invention does not form the restriction to the application's scope; every within the spirit and principle of the present invention design, any modification that one of skill in the art can make, be equal to and replace and within improvement etc. all should be included in protection scope of the present invention.
