Abstract
The utility model discloses a construction structures is moved to whole indulging of this line D roof beam, this construction structures is moved to whole indulging of this line D roof beam include that big coaster, steel sleeper, D roof beam, steel are shored, the jack, a plurality of big coasters are laid on existing railway line way, have placed a steel sleeper on every big coaster, assort sheeting caps, chuck, jimmy on the big coaster, and the installation steel sleeper is located according to a different intervals high position respectively in D roof beam both ends, and D roof beam both ends installation steel is shored, and the jack withstands the steel and shores. The utility model discloses a D roof beam is whole to be indulged and moves construction structures and can realize quick the indulging of D roof beam and move, reduces and blockades main points and construction process, reduces the instability and the risk of easily empting of D roof beam in removing, need not the contact net and has a power failure, has greatly released the railway transport capacity, not restricted by the station track, reduces and blockades main points, the saving engineering time.
Description
Technical field
The utility model belongs to construction of railways field, particularly relates to the overall vertical shift constructing structure of a kind of this line D beam.
Background technology
The prefabricated D beam of diplopore is divided hole-specifically in strengthening construction at railway frame structure, D type just beam hardened link is adopted according to designing requirement, under the condition of not interrupting railways train operation, 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, construction " skylight point " time is short, and the monolithic beam center of gravity of D type just beam is higher, bottom surface is narrow, is easy to topple in movement, directly there is potential safety hazard and risk tearing open in assembling construction, there is no larger security reliability.
Utility model content
The object of the utility model embodiment is to provide a kind of this line D beam overall vertical shift constructing structure, and be intended to solve traditional railway frame structure and divide diplopore prefabricated D beam hole-specifically strengthening construction operation is loaded down with trivial details, the engineering time is long, the problem of poor stability.
The utility model is achieved in that the overall vertical shift constructing structure of a kind of this line D beam comprises large coaster, steel sleeper, D beam, steel are shored, jack; Multiple large coaster is placed on existing railway circuit, each large coaster is placed with a steel sleeper, and D beam two ends install steel sleeper by different spacing at high level respectively, and D beam two ends are installed steel and shored, and jack withstands steel and shores.
Further, described large coaster is equipped with sleeper head, timber wedge, crowbar.
The overall vertical shift constructing structure of D beam of the present utility model can realize the quick vertical shift of D beam, reduce and block main points and working procedure, 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 structural representation of the overall vertical shift constructing structure of this line D beam that the utility model embodiment provides;
In figure: 1, large coaster; 2, steel sleeper; 3, steel is shored; 4, jack.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.There is not the innovation of method or software in the utility model.
Below in conjunction with drawings and the specific embodiments, application principle of the present utility model 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, 24mD 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 1, a steel sleeper 2 placed by each large coaster 1, 2.01m is respectively apart from D beam two ends, 4.69m, steel sleeper is installed at 7.37m place, connect bracket, after D beam promotes and puts in place, steel sleeper 2 above large coaster 1 and between large coaster 1 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 1, falling jack 4 makes D beam drop down onto and requires position, remove steel sleeper above circuit, connect fastening D beam.Concrete grammar is as follows:
Step one, according to work business " taking out one every six " rule request, be steel sleeper 2 by this line reinforcing place sleeper replacement;
Step 2, within the scope of the vertical shift of this line D beam, clear up D beam walk row of channels;
Step 3, outside circuit prepare 6 large coasters 1, a steel sleeper 2 placed by the large coaster 1 of every platform, large coaster assorted sheeting caps, timber wedge, crowbar;
Step 4, hydraulic jack 4 is transported to circuit D beam two ends in advance, D beam two ends are installed steel and are shored 3, and install oil pipe and oil pump, jack 4 withstands steel and shores 3;
Step 5, artificial being lifted by D beam two ends respectively put large coaster 1 in circuit, steel sleeper 2 is lifted and puts on large coaster, promote large coaster 1 respectively apart from 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;
Step 6, below D beam two ends steel shores 3 install join 4 700cm stroke hydraulic jack 4, make 2 D beam Integral liftings, make higher than flange of rail steel sleeper 5cm at the bottom of D beam, between large coaster 1 and steel sleeper 2, sheeting caps is filled in space, and timber wedge is urgent;
Step 7, remove large coaster 1 travelling wheel place timber wedge, promote large coaster 1 simultaneously, the vertical shift of D beam is reinforced position to this line, the urgent large coaster travelling wheel of timber wedge;
Step 8, below D beam two ends steel shores 3, hydraulic jack 4 is installed, overall jack-up D beam, large coaster 1 is not stressed, large coaster 1 is extracted out for 2 from steel sleeper above circuit, fall jack after rise, make D beam entirety drop down onto D beam-ends requirement position, remove steel sleeper 2, reinforcement by connection D beam above circuit.
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 utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
