Further optimization and improvement of the scheme are as follows: and the connecting sides of the supporting member, the floor slab and the side baffle are all n-shaped structures with two overhanging sides. The n-shaped structure with overhanging two sides ensures that the whole system is reasonable in stress, few in reinforcing bars, convenient to adjust the length and the size of the prefabricated part, flexible and variable. The overhanging pi-shaped structure makes the connection more stable and enhances the stability of the whole system.

Further optimization and improvement of the scheme are as follows: the prefabricated parts are all prefabricated from cement-based materials.

Further optimization and improvement of the scheme: the supporting member and the floor slab are both prefabricated by adopting common concrete. The platform is not heavy and mainly bears the load from the vertical direction, so that the common concrete can meet the requirement.

Further optimization and improvement of the scheme are as follows: the side baffle is prefabricated by UHPC material. The UHPC material has the characteristics of high strength, no need of reinforcement and suitability for a humid environment under a platform, and meanwhile, the UHPC material can be made to be very thin, has small self weight of the structure and is convenient to transport and install.

Further optimization and improvement of the scheme are as follows: the connecting angle code of the side baffle is UPHC, and stainless steel bolts are respectively fixed with the floor slab and the platform bottom plate.

Compared with the prior art, the utility model discloses the beneficial effect who brings does: the whole system has reasonable structural stress, is convenient to install and construct, avoids the reservation and the embedment of a station bottom plate, can adapt to the moist environment of an underground space, does not need later maintenance, has controllable construction cost and the like; the rigid connection is formed by pouring concrete, a stable and firm assembled platform system can be obtained, on-site formwork erection is not needed, the problems that the construction efficiency is low, the process is complex, the construction quality of components is difficult to guarantee and the like in the traditional cast-in-place operation can be solved, the stability of an assembled structure and the strength and construction quality of a connecting joint are improved, and the construction period is shortened; in addition, the size standardization of prefab is favorable to the utility model discloses an industrialization.
