[0002] In modern construction projects, with the development of urban construction, there are more and more underground structures such as high-rise buildings, large underground shopping malls, underground parking lots and subway stations. These underground structures often require deep foundation pits as the foundation space. Concrete pouring in deep foundation pits, especially large-volume concrete pouring, has become a key link. For example, on the raft foundation of a super-high-rise building, in order to meet the huge load transfer requirements of the superstructure, the raft foundation thickness may reach several meters and the area may reach thousands of square meters. The quality of this large-volume concrete pouring is directly related to the stability of the entire building.
[0003] At present, the methods for pouring large-volume concrete in deep foundation pits include tower crane hoisting, ground pump pouring, automobile pump pouring and chute pouring. Among them, automobile pump and chute pouring are common construction methods, but both methods are subject to certain limitations or have certain disadvantages. Automobile cranes are affected by the site and pouring position and may not be able to cover the pouring range. When setting up a chute, due to the deep foundation pit, it is necessary to set up pouring support lattice columns, which has high cost and long erection time. At the same time, due to the limitation of the chute, the pouring range is not flexible, and it is necessary to pour a section of concrete and dismantle a section of the chute, which makes the construction cumbersome.
