(4) installing a newly-built canopy supporting upright post and a temporary supporting structure, and installing an upper steel structure of the newly-built canopy;
(5) landscape platforms are arranged on two sides of the station;
(6) dismantling the temporary support of the newly-built canopy, and installing and decorating the roof panel of the newly-built canopy;
(7) and (4) dismantling the existing canopy, the movable protection canopy and the extension platform.
Each movable shed protecting unit consists of a front portal structure and a rear portal structure through a connection rod piece, each portal structure consists of a left upright post, a right upright post, a left cross beam and a right cross beam, the two cross beams are inclined upwards by a certain angle, and a longitudinal hanging rail is arranged below the front cross beam and the rear cross beam in a top structure which is connected at the end to form a slope top shape.
In the step (4), the newly-built canopy is in a cross-star shape and is divided into five parts, namely a left part, a middle part, a right part, an upper part and a lower part, firstly the canopy frameworks at the two ends of the track are installed, then the canopy frameworks at the two ends are connected by the main truss, then the canopy framework at the middle part is installed, and finally the canopy frameworks at the two sides of the track are installed.
In the step (2), a movable protective shed reverse support, a station pillar and a station reverse support are arranged below the side type station platform, and the movable protective shed reverse support and the station reverse support are detached after the step (7) is completed.
In step (3), after the movable shed protecting unit slides to a preset position above the existing station canopy, the roller supports of the movable shed protecting unit are converted into fixed supports, isolation structures on two sides of the movable shed protecting unit are installed, and meanwhile, the outer side of the platform is protected by facing edges.
The installation and decoration of the rainshed roof panel in the step (6) comprises the following steps: the rain shed main body steel structure and the steel base recheck and correct, the positioning of the adapter piece, the round pipe main keel and the secondary keel is realized, the installation of the ribbon and the water channel keel is realized, the processing of the special-shaped aluminum plate is realized, the installation of the bottom plate, the special-shaped aluminum plate and the glass rock wool is realized, the installation of the waterproof aluminum plate and the panel is realized, the installation of the ribbon and the float grass aluminum plate is realized, the installation of the transparent daylighting plate is realized, and the thin part is collected and glued and bottomed.
The step of dismantling the existing canopy and the movable protection canopy in the step (7) is as follows: install the lighting fixture and pass through to the lighting fixture with the equipment on the existing canopy in existing canopy below, remove the fixed stay who protects the canopy and convert the gyro wheel into and support, divide the segmentation to existing canopy, carry out structural connection with existing canopy and removal canopy unit, demolish the tie rod between existing canopy segmentation, the connection structure between disconnection existing canopy and the platform, will remove canopy unit and existing canopy segmentation slip to extend the platform and hang from.
And (4) performing patching construction on the landscape platform after the movable protection shed reverse support and the platform reverse support are removed.
And (7) after the step (7) is finished, installing the side type platform and decorating.
And after the installation of the side type platform and decoration and renovation are finished, equipment and decoration and renovation are carried out on the original platform.
The invention has the beneficial effects that:
the construction method of the invention concentrates continuous operation of dominant resources, fully compresses duration of key lines, carries out professional and partition organization according to the principle of first structure, later electromechanical, decoration, multiple parallels, multiple interpenetration and less running water, synchronously carries out construction of the canopy structure from the station house size mileage two ends to the center in parallel after the construction of the side type station structure is completed, simultaneously carries out interpenetration construction of landscape platform layers of the east-west side station house, fully utilizes the radius of an automobile crane and a crawler crane, and saves the middle transfer flow to the maximum extent.
The movable protection shed is used for supporting the newly-built canopy unit blocks in the rail-mounted area, the newly-built canopy unit blocks can be directly transported to the required design positions through the longitudinal movement of the movable protection shed units, the necessary support of the rail-mounted area canopy units and the top of the movable protection shed units of the transportation channel are fully closed, and necessary protection measures of an existing platform and a rail area are formed during the construction of the newly-built canopy unit blocks. After a plurality of movable shed protecting units are connected into a whole, necessary means and passages for hoisting and transporting the existing canopy in blocks can be formed by the aid of the lower hanging type rails attached to the movable shed protecting units. The movable protection shed integrates the functions of new and old canopy unit blocks stressed and supported, a transportation channel and a protection shed, avoids the repeated investment and the installation and dismantling workload of the supporting structure, saves the material and labor cost, and effectively saves the construction time.
Set up the transfer platform of extension platform as various machinery and material at old canopy both ends to the solution is smooth and easy and the narrow and small problem of construction space that leads to for satisfying the traffic, removes canopy unit and new, old canopy and all transports the hoist and mount on extending the platform, has reduced the material and has stacked the place.
Old canopy is not demolishd when newly-built canopy, does not influence the normal use originally at station, protects the protective structure of canopy unit concatenation for old canopy through a plurality of removals, guarantees construction safety. And after the new canopy is installed, the old canopy is dismantled, so that seamless connection of the new canopy and the old canopy is realized. The construction can be synchronously carried out at the two ends of the track, and the construction period is saved.
