[0002] During the concrete pouring construction of the main body of a high-rise building, the poured concrete is pumped to the higher concrete pouring layer by a ground pump. The ground pump is installed on the ground. A 300×300 mm hole is opened on the finished floor slab. The pump pipe of the ground pump passes through the hole and is connected from bottom to top to the working layer. When the ground pump is transporting concrete, it will generate a large pressure, which will cause the entire ground pump pipe to shake violently.

[0003] In the prior art, in order to maintain the stability of the ground pump pipe and reduce its shaking degree, so as to prevent the interface position of the pump pipe from being misaligned and causing slurry leakage, some wooden wedges are usually inserted into the reserved holes of the floor slab to fix the pump pipe; however, since this fixing method adopts a rigid connection fixing method, during the concrete pouring process, the pump pipe and the wooden planks will collide violently, and the wooden planks will collide with the floor slabs, making a huge noise, which is easy to damage the pump pipe, reducing the service life of the pump pipe, and is also easy to damage the surrounding floor slabs. Utility Model Content

[0004] In response to the problems raised by the above background technology, the purpose of this utility model is to provide a vertical fixed shock-absorbing device for concrete delivery pump pipes to solve the problems raised in the above background technology that the pump pipes violently collide with the floor slabs during concrete pouring, reducing the service life of the pump pipes, causing noise, and damaging the floor slabs.
