There is provided a liquid injection apparatus (30) for use in a method of lining the internal surface of a pipe. The apparatus comprises a push car having a frame structure (31), a liquid tank (32) for storing a necessary amount of liquid to be injected into the pipe, a liquid pump (40) for pumping the necessary amount of liquid so as to inject the liquid into the pipe, and a liquid injection controlling device (20) for controlling the pressure of the liquid being supplied through the liquid pump (40), for stopping the liquid injection after a predetermined amount of liquid has been injected into the pipe, and for stopping the liquid injection if the liquid pressure in the pipe changes beyond a predetermined range. The liquid tank (32), the liquid pump (40) and the liquid injection controlling device (20) are installed together in the push car so as to be easily movable. <IMAGE> |
