Step one, the outer preparation of point:
The first step, according to work business " taking out one every six " rule request, be steel sleeper by this line reinforcing place sleeper replacement;
Second step, within the scope of the vertical shift of this line D beam, clear up D beam walk row of channels;
3rd step, outside circuit, prepare large coaster, a steel sleeper placed by the large coaster of every platform, large coaster assorted sheeting caps, timber wedge, crowbar;
4th step, hydraulic jack is transported to circuit D beam two ends in advance, D beam two ends are installed steel and are shored, and install oil pipe and oil pump, jack withstands steel and shores;
Operation in step 2, point:
The first step, upper installation connect steel sleeper above former D beam hardened link;
Second step, D beam two ends steel shore below install hydraulic jack, overall jack-up D beam, make higher than flange of rail steel sleeper at the bottom of D beam, between large coaster and steel sleeper, sheeting caps is filled in space, the urgent large coaster travelling wheel of timber wedge;
3rd step, remove large coaster travelling wheel place timber wedge, promote large coaster simultaneously, the vertical shift of D beam is reinforced position to this line, the urgent large coaster travelling wheel of timber wedge;
4th step, falling D beam.
The first step, above described connection former D beam hardened link, the concrete grammar of steel sleeper is:
Artificial being lifted by D beam two ends respectively puts large coaster in circuit, is lifted by steel sleeper and puts on large coaster, promote large coaster respectively to specified location, the urgent large coaster travelling wheel of timber wedge, fixed lateral position, connection steel sleeper, fastening bracket.
4th step, the concrete grammar of described falling D beam is:
Shore below at D beam two ends steel and install hydraulic jack, overall jack-up D beam, makes large coaster not stress, and is extracted out by large coaster from steel sleeper above circuit, falls jack after rise, makes D beam entirety drop down onto D beam-ends requirement position, removes steel sleeper above circuit, reinforcement by connection D beam.
Construction method of the present invention can realize the quick vertical shift of D beam, reduces and blocks main points and working procedure, the unstability during reduction D beam moves and the risk of easily toppling over, have a power failure without the need to contact net, greatly release railway transport capacity, do not limit by station track, reduce and block main points, save the engineering time.
Accompanying drawing explanation
Fig. 1 is the overall longitudinal shift construction method flow chart of this line D beam that the embodiment of the present invention provides.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Below in conjunction with drawings and the specific embodiments, application principle of the present invention is further described.
In the 2-16m frame structure jacking construction of Xinzhou City peace East Street, divide holes prefabricated in existing railway west side, cross north with Pu up-downgoing, Xin river line, shunting neck, amount to 4 station tracks, 24m D beam hardened link is adopted in construction, arrange that calculating D beam need promote 45cm and exceed flange of rail steel sleeper according to on-the-spot D deck-molding position, existing line is put six large coasters, a steel sleeper placed by each large coaster, 2.01m is respectively apart from D beam two ends, 4.69m, steel sleeper is installed at 7.37m place, connect bracket, steel sleeper after D beam promotes and puts in place above large coaster and between large coaster with sheeting caps stuff up a crack and urgent timber wedge, vertical shift reinforces position to this line, slightly play D beam, remove large coaster, falling jack makes D beam drop down onto and requires position, remove steel sleeper above circuit, connect fastening D beam.Concrete grammar is as follows:
S101, according to work business " taking out one every six " rule request, be steel sleeper by this line reinforcing place sleeper replacement;
S102, within the scope of the vertical shift of this line D beam, clear up D beam walk row of channels;
S103, outside circuit prepare 6 large coasters, a steel sleeper placed by the large coaster of every platform, large coaster assorted sheeting caps, timber wedge, crowbar;
S104, hydraulic jack is transported to circuit D beam two ends in advance, D beam two ends are installed steel and are shored, and install oil pipe and oil pump, jack withstands steel and shores;
S105, artificial being lifted by D beam two ends respectively put large coaster in circuit, steel sleeper is lifted and puts on large coaster, promote large coaster respectively to distance 2.01m, 4.69m, 7.37m place, D beam two ends, the urgent large coaster travelling wheel of timber wedge, fixed lateral position, connection steel sleeper, fastening bracket;
S106, D beam two ends steel shore below install join 4 70cm stroke hydraulic jack, make 2 D beam Integral liftings, make higher than flange of rail steel sleeper 5cm at the bottom of D beam, between large coaster and circuit, sheeting caps is filled in space, the urgent large coaster travelling wheel of timber wedge;
S107, remove large coaster travelling wheel place timber wedge, promote large coaster simultaneously, the vertical shift of D beam is reinforced position to this line, and large coaster travelling wheel killed by timber wedge;
S108, D beam two ends steel shore below install hydraulic jack, overall jack-up D beam, makes large coaster not stress, large coaster is extracted out from steel sleeper above circuit, fall jack after rise, D beam entirety dropped down onto require position, remove steel sleeper above circuit, reinforcement by connection D beam.
Note in construction:
1. ensure that the large coaster wheel of every platform normally runs.
2. above circuit, steel sleeper requires to be connected fastening with D beam, adopts electric wrench fastening.
3. measure good large coaster in advance and fall position after rise, guarantee that contraposition is accurate, carry out next procedure fast.
When 4. adopting hydraulic jack jack-up D beam, require the overall jack-up of D beam, steady, safety.
5. after D back rises and is connected with steel sleeper above circuit, D beam lower end uses 4m they sup-port, does not conflict during to guarantee to fall D beam after rise with reinforcing position steel sleeper.
6. D back rises, slippage, whereabouts will assume unified command of, act in agreement and guarantee safety.
Conventional construction method need adopt the large coaster of slide rail, and the defeated D beam of movement is to reinforcing position in length and breadth, and working procedure is loaded down with trivial details, and construction " skylight point " time is short, and the monolithic beam center of gravity of D type just beam is higher, and bottom surface is narrow, is easy to topple in movement.Especially the D24m just long 24.5m of beam girder, wide 45cm, high 130cm, height is 3 times of bottom width, and such configuration is stability extreme difference in monolithic is directly mobile, directly there is potential safety hazard and risk tearing open in assembling construction, does not have larger security reliability.Adopt overall D beam to connect and coordinate large coaster straight skidding, the resistance to overturning of D beam can be ensured, save working procedure, ensure open-minded on schedule.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
