The invention relates to a cast-in-place concrete filling tire body. The cast-in-place concrete filling tire body comprises a base body of the tire body and an annular inflation liner which is embedded into the base body of the tire body and is fixedly sealed in the bas body of the tire body. According to the cast-in-place concrete filling tire body, a supporting body is added in a box body of the base body of the tire body to improve the support between the top surface and the bottom surface of the base body of the tire body, and the annular inflation liner is embedded into the base body of the tire body and is capable of supporting each circumferential wall of the base body of the tire body, so that the whole supporting strength of the tire body is higher; once the inflation liner is directly contacted with open fire, the wall of the inflation liner can be burnt, therefore, the burning strength of the inflation liner is low, and the burning time of the inflation liner is short, and furthermore, the problem of the prior art that other objects can be ignited when fillers in the cast-in-place concrete filling tire body are burnt can be solved.
