[0042] In a specific embodiment of the present invention, the early dismantling formwork system is to first set up an early dismantling support formwork system in the trolley formwork area, and after the concrete strength reaches 75%, separate the connection between the formwork at the early dismantling support and the integral steel formwork. The quick dismantling function of the integral steel formwork of the platform canopy is realized, thereby achieving rapid turnover of the formwork and rapid formwork and assembly line construction.

[0043] In a specific embodiment of the present invention, the early dismantling support is composed of an adjustable support, a square column and an early dismantling formwork adapter. The square column is made of a 150×150×8mm square tube, and the adjustable support uses a trailer support device. The early dismantling formwork can be quickly disassembled by connecting pins with the integral steel formwork. The design spacing of the early dismantling support is not more than 4m. The remaining early dismantling support system plays a fixed supporting role for the cantilever structure that has been poured. The early dismantling support system can be dismantled only when the concrete strength reaches 100%, and it can be used for turnover of the next section.

[0044] In a specific implementation of the present invention, in S4, the canopy reinforcement is tied and the canopy structure column combined steel formwork is installed, and the column bottom steel formwork is directly placed vertically and closely on the platform support layer. The above formwork is supported by loose formwork.

[0045] In a specific embodiment of the present invention, in S6, the demolding step is: removing the upper loose mold part, removing the connection between the templates at the early support, removing the cross beam support at the bottom of the beam, withdrawing the large template system of the canopy as a whole, folding the large template and adjusting the trolley to the ground support.

[0046] In a specific implementation of the present invention, in S1, the size, shape and material of the canopy are determined according to actual needs and site conditions.

[0047] In a specific embodiment of the present invention, the following steps are also included

[0048] Foundation construction: According to the design requirements, the canopy foundation is constructed, including digging the foundation pit and pouring the concrete foundation;

[0049] Sealing treatment: Seal the connecting parts of the awning to prevent rainwater leakage.

[0050] Surface treatment: Treat the surface of the awning to improve its appearance and durability.

[0051] In a specific embodiment of the present invention, the surface of the awning is processed, including painting and coating.

[0052] In a specific embodiment of the present invention, the following operations are performed after the construction is completed.

[0053] Quality inspection: Carry out quality inspection on the awning to ensure that the awning meets the relevant standards and requirements.

[0054] Cleaning and acceptance: Clean up the construction site and conduct final acceptance of the awning to ensure the construction quality and use effect of the awning.

[0055] In a specific implementation of the present invention, the canopy is subjected to quality inspection, including structural strength, sealing performance and appearance quality.

[0056] Also included is a rain canopy drainage method, comprising the following steps:

[0057] 1. A water collecting trough is arranged at the edge of the canopy, and the water collecting trough is sealed and connected to the edge of the canopy;

[0058] 2. A drainage hole is provided at the bottom of the water collection tank, and the drainage hole is connected to a drainage pipe;

[0059] 3. A water seal device is provided at the outlet of the drain pipe, and the height of the water seal device is greater than the diameter of the drain pipe.

[0060] The width of the water collecting trough is 10-20 cm, the diameter of the drainage hole is 10-15 mm, the diameter of the drainage pipe is 10 cm, and the height of the water sealing device is 5-10 cm.

[0061] The canopy drainage method of the present invention can effectively collect rainwater by setting a water collection trough at the edge of the canopy to prevent rainwater from accumulating on the canopy. By setting a drainage hole at the bottom of the water collection trough, rainwater can be quickly discharged. By setting a water sealing device at the outlet of the drainage pipe, rainwater backflow can be effectively prevented, thereby improving the drainage efficiency of the canopy.

[0062] The water collecting trough is arranged at the edge of the canopy body to collect rainwater; the drainage pipe connects the water collecting trough and the drainage outlet to discharge the collected rainwater.

[0063] In this embodiment, the depth of the water collection tank is 5-10 cm, the diameter of the drainage pipe is 5-10 cm, the drainage port is arranged on the ground, and the water collection tank and the drainage pipe are both made of PVC material.

[0064] When rain falls on the canopy body, it will flow into the water collection tank along the edge of the canopy body. The rainwater in the water collection tank will flow into the drain outlet through the drain pipe, and finally the canopy rainwater will be led out of the platform and discharged into the surrounding station drainage ditch. The canopy drainage system of this solution has a simple structure and good drainage effect, which can effectively prevent rainwater from accumulating on the canopy and ensure the normal use of the canopy.

[0065] During the construction of the platform canopy, it is necessary to lay various pipelines, such as cables, communication optical cables, water pipes, drainage pipes, etc. These pipelines usually need to be pre-buried under the platform canopy to ensure the flatness and aesthetics of the platform canopy. However, the traditional pipeline pre-buried method has some problems, such as the pipeline is easily damaged, and the flatness and aesthetics of the platform canopy are difficult to ensure.

[0066] In order to solve the above problems, the present invention provides a method for pre-burying pipelines on the ground of a platform canopy. The method comprises the following steps:

[0067] 1. Dig a trench on the platform canopy floor with a depth of 0.5 meters and a width of 0.3 meters;

[0068] 2. Laying cables, communication optical cables, water pipes, drainage pipes and other pipelines in the trench;

[0069] 3. Lay a 0.1-meter-thick sand layer above the pipeline as a protective layer;

[0070] 4. Backfill soil above the protective layer. The height of the backfill soil should be the same as the height of the platform canopy ground.

[0071] It can effectively protect pipelines and prevent them from being damaged, and at the same time it can improve the flatness and aesthetics of the platform canopy floor.

[0072] The platform canopy construction design process can reduce construction costs, and modular assembly on site can reduce construction costs; it has the advantages of high construction efficiency, reliable quality, good aesthetics, etc., which can meet the needs of different users;

[0074] Controllability of construction period: The construction efficiency is 11 days / section, and there are few factors affecting the construction period.

[0075] Technical reliability: mechanized and intelligent construction, controllable construction quality and reliable technology.

[0076] Economical: Total construction cost is 215.55 yuan / ㎡.

[0077] Safety: The construction trolley is equipped with standard working stairs and standardized edge protection, which reduces safety risks. There are fewer turnover materials and less workload for safe and civilized construction.

[0078] The platform canopy of Guiping North Station is 550m long, with 62 axes and 6 expansion joints, each with a width of 100mm. The parallel track direction is a frame structure system, and the vertical track direction is a partial single-column Y-shaped cantilever structure, which is a single-column cantilever structure. The maximum beam section size is 1000*300mm, the plate thickness is 130mm, and the concrete strength is C35.
