fourthly, sequentially installing the assembled standard frame body (4), the clamping damping assembly (6) and the top frame body (5) based on design, wherein a spring (65) in the clamping damping assembly (6) extends into the top vertical rod (51), and the diameter of the spring (65) is adapted to the inner diameter of the top vertical rod (51); the clamping vibration upper rod (63) and the clamping vibration top plate (64) which are connected with the spring (65) also extend into the top vertical rod (51);
wherein, the height and the expansion amount of the spring (65) are adapted to the upward impact force of the pouring of the pump pipe (7); the clamping vibration top plate (64) is a circular plate, the diameter of the clamping vibration top plate is larger than that of the clamping vibration top rod (63), and the clamping vibration top rod (63) and the bottom end of the top vertical rod (51) are detachably connected with a limiting plate; the limiting plate is an annular plate, and the inner diameter of the annular plate is larger than the diameter of the clamping vibration upper rod (63) and smaller than the diameter of the clamping vibration top plate (64)
Fifthly, during fine adjustment during installation, the fine adjustment is carried out through the standard vertical connecting cylinder (47) between the standard frame bodies (4) and/or the standard vertical connecting cylinder (47) between the standard frame bodies (4) and the bottom vertical rod (31);
sixthly, after the frame body is installed, the verticality and the position of the frame body are retested, and after the frame body is qualified or adjusted to be qualified, a transverse clamping rod (66), a transverse connecting hoop (67) and a clamping vibration pipe connecting hoop (68) are installed on the clamping damping assembly (6); wherein the two semi-arc plates of the clamping vibration pipe connecting hoop (68) are temporarily connected; after the transverse clamping rod (66) and the transverse connecting hoop (67) are installed and positioned, the pump pipe (7) is connected and fixed in the clamping vibration pipe connecting hoop (68) in a penetrating way, and then the position of the clamping vibration pipe connecting hoop (68) is retested;
seventhly, according to design requirements, inclined struts (9) are detachably mounted on the periphery of one or more standard frame bodies (4), and the inclined struts (9) are symmetrically connected and fixed with the base plate (2); and the stress sensor and the strain sensor are connected at the center of the bottom scissor supports (35) (35); after the whole frame body is stable, the height and the position of the pump pipe (7) are measured again before the pump pipe works, and concrete pouring construction of the pump pipe (7) is carried out after the requirement is met.
