Description
Technical field
The present invention relates to the maintenance of the spray of U-shaped beam body, specifically U-shaped beam body integral type sprinkling curing system and side
Method.
Background technique
Urban track traffic is the important growth point of Chinese economic development, and one that Chinese big and medium-sized cities are developed
Mark.Urban Rail Transit Development is to solve urban road congestion, reduce that haze is most effective, the most fundamental method.U-shaped beam is
International advanced design concept is introduced, Stochastic FEM is designed to this new structure of the U-shaped beams of concrete of thin walled aperture, is arranged
Vehicle traveling is inside opening U beam.U beam not only good appearance, reduces overall structure height, and structural concrete is frivolous, at
This is relatively low, and all tool has great advantage in terms of noise reduction and damping.It is prefabricated with the development of the city with the progress of science and technology
U beam will be gradually applied to inter-city rail transit engineering field and obtain as a kind of novel large span prestressed concrete structure
It is the direction of Construction of Urban Rail Traffic development and application to all-round popularization.
Since the appearance and structure type of U-shaped beam are more special, the concrete of web and bottom plate is more frivolous, beam body by
Power performance box beam different from the past and T-type girder construction, and engineer application has strict requirements to the intensity of U-shaped beam.It is based on
Above-mentioned reason, it is necessary to prefabricated U-shaped beam is conserved, for example, by using spray water curing, avoid U-shaped beam occur cracking or intensity not
The problems such as up to standard, guarantees the prefabricated quality and construction safety of U-shaped beam.
Since U-shaped beam enters China soon, and at home, the application in terms of rail traffic and research are less, and current is U-shaped
Beam maintenance technology is still far from perfect, it is known that maintenance method also continue to use on the traditional artificial maintenance method of box beam, T beam etc..But people
The randomness and poor repeatability of work maintenance, time-consuming, labor intensity is big, conserves the problems such as low precision, can all cause U-shaped beam
Maintenance not in time, non-uniform spraying, spray it is not in place, influence the quality problems of prefabricated U beam.And prefabricated U-shaped girder construction is special, U
The maintenance of web position is more difficult inside and outside type beam body.
It is ability in conclusion inventing a kind of method for being able to solve the maintenance of current U beam to solve existing great number of issues
The problem of outstanding problem in domain and U-shaped beam promote and apply urgent need to resolve in urban track traffic.
Summary of the invention
In view of the above-mentioned problems, in order to solve the deficiencies in the prior art, spy's setting high degree of automation, maintenance it is with high accuracy
Integral type sprinkling curing system and method solve traditional box beam et al. work maintenance method institute to fill up the blank of U beam maintenance method
Existing maintenance is not in time, non-uniform spraying, spray not in place and randomness and poor repeatability, time-consuming, hand labor is strong
Degree is big, conserves the problems such as low precision.
U-shaped beam body integral type sprinkling curing system, including the water supply pipe being set in U-shaped beam, water supply pipe includes substantially

Multiple spray head outflows, realize to the spray of U-shaped beam body, avoid traditional artificial spray, not only save the time, but also spray more equal
Even, for the structure for being bonded U-shaped beam, the second pipeline is equipped with two sections.
Further, for the uniformity of spray, multiple second pipelines are symmetrical as center both sides using the first pipeline
Setting.
Further, in order to adapt to the shape of U-shaped beam body end face, second pipeline is L shape, and the second pipeline is along U-shaped
The end face of beam is arranged, the spray head rotatably with the second piping connection.
Further, the top of the second pipeline is equipped with third pipeline, and third pipeline is vertically arranged with the second pipeline, third pipe
Curb U-shaped beam length axis two sides upper surface setting, the spray head be set to third pipeline on.
Alternatively, in order to once spray broad covered area, meanwhile, spray time is saved, the third pipeline includes multiple branches
The 4th pipeline, the spray head be set to the 4th pipeline on, the spray head rotatably with the 4th piping connection.
Further, the 4th pipeline include with the vertically disposed horizontal tube of third pipeline, set in one end of horizontal tube
There is one section of vertical pipe, the vertical bottom of the tube of web outside is also connected with inclination broken pipe outside U-shaped beam, and the spray head is set to vertical pipe
And in inclination broken pipe.
Alternatively, the 4th pipeline include with the vertically disposed horizontal tube of third pipeline, in horizontal one end, one Duan Shuzhi is set
Pipe is equipped with the 5th pipeline in the bottom of vertical pipe, and the spray head is set on the 5th pipeline.
Further, it is equipped with geotextiles between the horizontal tube and U-shaped beam and carries out damping, must also adopt according to the actual situation
Take suitable fixation.
Further, the starting point of first pipeline passes through piping connection with the reservoir for filling ejecting liquid, in pipe
Road setting water management system, holds and is equipped with frequency-conversionbooster booster water pump, the water pump and water management system in the reservoir at water source
Connection, is achieved in automatic control, simple and convenient, as long as turning on the switch, controls upper water by water management system.
Another program provided by the invention is: the spray maintenance process to U-shaped beam body, and the spray maintenance system is arranged
System.
The beneficial effects of the present invention are:
1, by the way that water supply pipe is arranged in U-shaped beam, and by the on-off of water management system control water supply pipe, and by spraying
Head sprays maintenance liquid for the maintenance of U-shaped beam, is sprayed without man-hour manually hand-held pipeline, and spray is more uniform, time-consuming shorter.
2, third pipeline is cooperated by the 4th pipeline, realizes effective spray to outside in web outside U-shaped beam, meanwhile, spray
The maintenance liquid for pouring the outer web of U-shaped beam flows to lower from eminence, meets the flowing trend of liquid, reduces repetition spray, support
It is high to protect precision.
3, by the way that the second pipeline is set as L shape, it is more bonded the shape of U-shaped beam, while passing through vertical pipe and inclination broken pipe
Setting, be more in line with the shape of U-shaped beam body, further improve spray quality.
