Description
Technical field
The present invention relates to a kind of technology for bridge under running line in bridge bridge cable engineering, particularly a kind of built-up type transition running line cage based on bridge running line under cable.
Background technology
In bridge bridge cable engineering, it is fixing that cable testing bridge is positioned at the bridge abdomen hanging of bridge both sides, cable causes from bridge floor must by one section of free face bridge abdomen cable testing bridge below bridge floor, site operation is except arranging except lower bridge service platform at free face, for control difficult problems such as bending radius when bridge lays under solution cable, wall pressure, damages, generic way adopts to set up steel pipe frame on lower bridge service platform, and in frame body, multiple spot installing annular coaster controls. But described annular coaster needs to be arranged by calculating and the in-site modeling of complexity, in the provisioning process if there is local deviation, it is easy to cause that radius of cable bends is excessively little, wall pressure increases, damage cable; In addition, annular coaster owing to cable is not located, must adjust position in real time in cable running process, waste time and energy after arranging, and efficiency is low, and subsequent construction is numerous and diverse.
Summary of the invention
It is an object of the invention to provide the built-up type transition running line cage based on bridge running line under cable of a kind of time saving and energy saving, efficiency height, non-easy damaged cable according to the deficiencies in the prior art part.
It is an object of the invention to be realized by following approach:
Based on the built-up type transition running line cage of bridge running line under cable, its structure main points are, include first section of running line cage, tail section running line cage and a plurality of middle section running line cage, wherein, the constitution element of first section of running line cage, tail section running line cage and each middle section running line cage has included guide roller frame, angle steel framework and steel pipe; Described guide roller frame is trilateral or square planar framework, every bar limit of framework is all provided with the waist drum shape pulley of a waist line indent, the pulley waist line on every bar limit forms the space of a similar round in framework, and this spatial area is adaptive with the cable cross section to be passed through; Described angle steel framework and guide roller frame are adaptive, are also trilateral or square framework, are that limit is formed taking angle steel, each angle steel is reserved with connecting screw hole; The two then is connected to get up by steel pipe by connecting the corresponding vertex of guide roller frame and angle steel framework, thus forms a kind of caged framework structure;
Concrete, first section of running line cage is identical with tail section running line basket structure, the steel pipe adopted is straight shape steel tube, and this first section of running line cage and tail section running line cage are by straight shape steel tube and lay respectively at straight shape steel tube two ends and a guide roller frame being connected of shape steel tube straight with this, an angle steel framework form; The steel pipe that middle section running line cage adopts is fan-shaped steel pipe, and the both ends of this sector steel pipe are connected to an angle steel framework, and guide roller frame is then positioned at the mid-way of fan-shaped steel pipe;
The angle steel framework of first section of running line cage is screwed into connecting screw hole by bolt and be fixedly connected with the angle steel framework of middle section running line cage one end, transition running line cage adopts multiple middle section running line cage head and the tail to be connected to form section in the middle of arc, the angle steel framework of the other end of last middle section running line cage then angle steel framework with tail section running line cage be bolted to connection.
Section and tail section running line cage in the middle of first section of running line cage, arc are just constituted the built-up type transition running line cage for bridge running line under cable of the present invention after sequentially connecting. Wherein, it is possible to adjust the quantity of the middle section running line cage of arc intermediate stage as required, when making, it is also possible to according to the radian size of steel pipe fan-shaped on section running line cage in the middle of the processing of the structure of concrete bridge. During use, cable is introduced the guide roller frame of first section of running line cage, under the drive of waist drum shape pulley and under action of gravity, cable sequentially passes the guide roller frame of multiple middle section running line cage in built-up type transition running line cage, last draw from the guide roller frame of tail section running line cage, complete bridge running line under cable.
First section of running line cage of the present invention, tail section running line cage and middle section running line cage are all the component units of built-up type transition running line cage; produce with the structure of modularization; arbitrary combination can be carried out according to actual needs during installation; lower bridge Piecemeal erection can be completed by manpower to fix; or adopt after bridge floor segmentation series connection assembling; utilize the auxiliary lifting of crane fixing on the operational platform; forming a full guard at lower bridge free face and lay passage, cable can be worn running line cage from bridge floor and cause the crane span structure below bridge abdomen. Constructing operation is simple and convenient, time saving and energy saving, efficiency height, and cable all primings in caged framework, and cable is played the effect of four directions encirclement by running line cage, is therefore not easily damaged to cable.
Described angle steel framework is fixedly connected with steel pipe by welding. Described guide roller frame is fixedly connected with steel pipe by welding.
Owing to the top of each angle steel framework and guide roller frame can be connected to steel pipe, every root steel pipe all needs to connect a summit of a framework, owing to adopting modular design, therefore each module can be fixed connection by welding, to reach most stable structure. And only need between module with module to be undertaken being connected by bolt.
In sum, the technology feature of the present invention is:
1, owing to adopting modular point to install, it is possible to integrated molding installation, eliminating complicated construction and calculate and in-site modeling operation, under effectively solving cable, bridge bending radius, wall pressure, damage etc. control a difficult problem; Simultaneously can also cost saving: adopt segmentation, built-up type, trucking costs can be reduced while solving a long part transport difficult problem and crane uses platform class rental expenses.
2, simplicity is installed. It is simple to operate that section is connected the common zinc coated bolt of employing with section, it is not necessary to by external impetus, equipment, also can complete to install fixing, time saving and energy saving by means of only manpower.
3, use safety. Once shaped can be installed, cable running process need not carry out two sub-band load adjustments by workmen again, ensure construction safety; Improve construction operation efficiency simultaneously, reduce and manually work.
4, use range is wide. The present invention can use in tunnel, underground or similar engineering.
