Description
Technical Field
The invention relates to a platform plate of a subway station and a construction technology thereof, in particular to a prefabricated platform plate of the subway station and a lifting installation method thereof.
Background
In order to facilitate passengers to get on or off, a station board is required to be arranged at a subway station. Because of the particularity of the position of the platform, the platform plate is generally not poured simultaneously with a main body of a station, and particularly, the platform plate needs to be poured at the later stage at the station which needs to be passed by shield construction.
The subway station generally needs to be used as a shield interval work starting or arrival site in a construction stage, so that the construction of a platform structure can be carried out when the construction of a main structure is completed and the construction of intervals at two ends of the station does not need to occupy a platform structure area. The construction method is characterized in that air duct reinforcing steel bars are reserved during the construction period of a main structure of the subway station, and after the main structure is finished, a platform plate is poured in a mode of binding the reinforcing steel bars and pouring concrete on a construction site and is connected with the main structure of the subway station into a whole. However, the construction method of the cast-in-place platform slab in the subway station has some problems, mainly including: firstly, more manpower and material resources are required to be invested in a construction site for construction, the construction procedures are more, all structural components need to be manufactured and completed in the construction site, and the concrete needs to wait for the age of the concrete, so that the production mode has low industrialization degree, low construction efficiency and long construction period; secondly, the existing construction method of the platform plate cast-in-place method in the subway station also has the problems of large material, resource and energy consumption, large quantity of construction waste, poor construction environment, large on-site dust pollution, cross operation with interval construction, mutual restriction of construction periods and the like; can not meet the requirements of high quality, high efficiency, energy conservation and environmental protection for sustainable development and construction; thirdly, due to the structural and positional particularity of the station bedplate, the construction space is narrow, concrete vibration and surface floating are difficult, and the construction quality is not easy to guarantee; fourthly, the construction of the platform plate inside the subway station by adopting a cast-in-place method means that civil engineering construction needs secondary approach, and later electromechanical installation and decoration time are often occupied, so that the whole opening period is directly influenced.
Although the problem caused by the cast-in-place construction method is solved in the Chinese utility model patent (publication No. CN 208933841U), in the utility model patent, two supporting arms 5 are respectively arranged on two sides of the top of the upright post 2; the prefabricated station board 1 is erected on the supporting arm 5; the section of each supporting arm 5 is I-shaped, the two supporting arms 5 are symmetrically distributed on two sides of the upright post 2, and the end parts of the two supporting arms 5 are respectively connected with the outer side surfaces of the two wing plates 6 of the upright post 2 in a welding mode; the support arm 5 comprises a web 7, a top plate 8 and a bottom plate 9. The web plate 7 of the support arm 5 is arranged along the vertical direction, and the web plate 7 is connected between the bottom plate 9 and the top plate 8; the top plate 8 is arranged along the horizontal direction and is used for supporting the prefabrication station plate 1; a reinforcing plate 10 is arranged between the two wing plates 6 of the upright post 2; the joint of the bottom plate 9 and the wing plate 6 of the supporting arm 5 is flush with the reinforcing plate 10; the two sides of the reinforcing plate 10 are respectively connected with the inner side surfaces of the two wing plates 6 of the upright post 2 in a welding mode; therefore, the utility model discloses a bearing structure is complicated, and the cost of manufacture is higher. In addition, in the utility model, the bottom end of the upright post 2 is fixedly arranged on the ground 3, the ground 3 is a station bottom plate or a railway bed edge, the upright post 2 is made of I-shaped steel, a support plate 4 is welded at the bottom end of the upright post, and an inclined strut 13 is arranged between the support plate 4 and the upright post 2; the supporting plate 4 is fixedly arranged on the ground 3 through a chemical bolt 12; a post-cast concrete protection pier 11 is arranged at the joint of the bottom end of the upright post 2 and the ground 3; the bottom surface of the post-cast concrete protection pier 11 is tightly attached to the ground, and the post-cast concrete protection pier 11 wraps the bottom end of the stand column 2 and the support plate 4; therefore, the upright post 2 is complex to install, time-consuming and labor-consuming to install and high in construction cost. In addition, in the utility model, the upright post 2 is installed at a preset position of the station, the post-cast concrete protection pier 11 is poured, and then each prefabricated station plate 1 is laid on the top of the upright post 2; it can be seen that the prefabricated station board 1 is laid on the top of the upright post 2, and during laying, the prefabricated station board 1 is not easy to position, installation is complex, installation wastes time and labor, construction cost is increased, and the prefabricated station board 1 slides on the upright post 2 easily in the using process, so that the stability of the whole structure is poor.
